No, it would need to be implemented into the Jython engine.

No, as this should be done with the means jython allows for, if any.

Hence, what you could do is the following: try to research jython itself
for the means it offers for terminating running jython threads
(forcefully) and then implement that in the Jython engine. If you think
that you were able to find a generic solution that adheres to the Jython
philosophy then please make your patch available via Issuezilla.

Having said all of this (which also means, that I admit of not having a
working knowledge about the inner workings of Jython), maybe there are
others on this list who may have already done that or have an advice
that could help you. (One idea could be to somehow get at the Thread
object on which the jython script executes and invoke interrupt() on it.)

HTH,

regarding BSFEngine.terminate

2009-10-28T20:20:35Z

Hi guys,
 
If I run infinite loop in a jython script (in separate thread) and call BSFEninge.terminate
from a separate thread it does not seem to terminate the jython script.
 
I see that the JythonEngine which is a BSFEngine implementation for the jython script does
not override the terminate method 
to actually terminate the jython script. We are using the 2.4 version of bsf and 2.1 version
of jython.
 
Is this feature provided in the newer releases of BSF? 
 
If not is there any other mechanism to kill the jython script running within the bean shell.
 
 
Thanks
Suresh

In the move of some taglibs to Tomcat, the BSF taglib got retired

2009-10-09T10:18:31Z

Hi there,

just learned from the announcement that in the process of moving taglibs
from Jakarta to Tomcat a lot of taglibs got retired, among them the BSF
taglib.

Not sure at the moment how Tomcat will allow for creating JSPs that
embed code in scripting languages, which was one of the original
applications of BSF, when it was originally developed at IBM (as a
matter of fact, IBM's WebSphere distributed BSF in order to enable Java
Server Page authors to embed scripts in any of its supported scripting
languages, very much like MS allows for in their ASPs).

So for those who have a need for the BSF taglib, here the relevant links:

Information about BSF taglib and examples on how to use it:

    

Download BSF taglib from:

    

Retired taglibs as of 2009-10:

Thanks Ant, I downloaded the release and tried it out and it seems like the
issue is now resolved. Thanks for the help.

Thanks,
Keith.

Re: Can JRuby 1.1.2 be used with BSF?

2009-04-19T18:03:54Z

Just an FYI on the BSF 2.0 beta3 release, its taking a while to work out 
how to get the website updated but the artifacts are now released and 
available in the maven repository and distribution area if anyone needs to 
start using them before the release announcement is made when the website 
is updated.

There's been no discussion on the next release. If you need one with that 
fix i guess we could do one, though i'm off on vacation today so I 
wouldn't be able to help with that till after March 15th.

Hi Ant,

Yes I feared so. Is there any timeline as to when this would happen?

Looks like no, the JRuby engine used by BSF 3.0-beta2 doesn't work with 
JRuby 1.1.2 or 1.1.3 as there have been some non-compatible changes. We 
need to upgrade BSF to the latest engine which works with JRuby 1.1.3 and 
the earlier JRuby releases.

Not quite sure, what you would like to achieve and what obstacles you
foresee at the moment. Could you elaborate a little bit more, what you
would like to achieve?

Rony,

This is not quite what I want to do though.  From your example below, I 
need to identify all the places in the script that do a 
bsf.lookupBean(...) and get the value of the string being passed in. Given 
that this could be a variable, it may be very difficult, but I may be 
willing to restrict our usage such that the value would always be an 
inlined constant.  Also, I'd really like to know the type of the object 
being set on the lhs.   Any hopes for any of that?  Thanks.

In BSF 2.4 you would first register those Java objects with the
BSFRegistry using the BSFManager's declareBean() or registerBean() that
the script should have access to. Then in the script you would use
BSFLookup() to gain access to the Java object stored in the BSFRegistry.

Here's a starting point to study BSFManager's members online:

Here's an example from the BSF samples in which "ScriptedUI.java"
creates an awt based user-interface, registers some (GUI) Java objects,
invokes a JavaScript script depending on the filetype (e.g. "ui.js" will
invoke JavaScript) which then runs and retrieves the registered object
and interacts with it. To use this you need to issue "java ScriptedUI
ui.js".

Identifying required properities

2009-02-09T14:34:03Z

I'm new to BSF, so be gentle...I'm wondering if, given an arbitrary 
script, there is a way to determine the beans that need to be declared for 
the script to execute without throwing 'undefined' exceptions.  For 
example, 


String s;
System.out.printl(s);


I'm assuming that 's' must be declared before the script will execute 
properly, but how can I figure out whether it is 's' or some other symbol. 
I'd also like to understand the type of the required symbol.  Thanks for 
any help.

BSF to add a scripting language to OpenOffice.org ...

2008-11-20T17:08:04Z

Hi there,

this year's OpenOffice conference took place in Beijing/Peking at the
beginning of November (at the same time the US Apache conference took
place).

Among the many talks there was one about adding a scripting language to
OpenOffice org (a.k.a. "OOo") using BSF by me, for which the slides are
available online already. [OOo's scripting framework itself is not
implemented in C++ but in Java, therefore BSF fits very nicely into it.]
All the presentations were videotaped and the tapes are supposed to be
made available at the end of November.

Cf. , resp.

Thursday presenatations, resp.

the presentation introducing BSF.

Should you contemplate to add your favorite scripting language to OOo
using BSF, you should also look into what you could/should do to ease
programming/scripting OOo. The presentation

stresses the areas in the OOo UNO ("Universal Network Objects", a
coarsley CORBA-like) component architecture for which one should/could
create specific support for a scripting language.

Should you have any questions in this context, just come forward and ask
them.

As you can see, ASF's BSF being a "matured" technology has many
interesting applications...

Missing java engine et.al (Re: evaluating simple string "2 == 2"

No, not really. Supposedly the "java" and "javaclass" engines, as their
source is in the BSF 2.4 archive, should be built and distributed with
BSF 2.4 (as well as the "jexl" engine). Looking at the engines in the
current distribution

reveals the following engines are already part of it: "jacl",
"javascript", "jython", "netrexx", and "xslt".

Please open a JIRA issue for this (as well as for the missing "BSF_Log"
and "BSF_LogFactory").

---

In the meantime, you can get a binary distribution with all BSF engines
for BSF 2.4 (as well as a slightly advanced version of BSF 2.4) from
.
After unpacking that zip-archive, you will find a jar-file named
"bsf-v244-20080704.jar". Just replace the official BSF 2.4 with that
version (which contains all official engines as well as "BSF_Log" and
"BSF_LogFactory").

HTH,

---rony

P.S.: Will become able to (finally!) start to tackle all open BSF-JIRA
issues in the next weeks, such that I would be able to go over these two
JIRA issues of yours as well.

Re: evaluating simple string "2 == 2"

2008-10-16T13:51:50Z

Hi Raza,

firstly, Jack is right, of course, there needs to be a Logger utility.

However, BSF 2.4 is supposed to be delivered with a minimal Logger named
"BSF_Log" (with "BSF_LogFactory"), but this class is not part of the
official BSF 2.4 binary distribution
.
The purpose of it would be to have the logging facility operational,
even if you would not have any other logging facilitiy at hand; not
distributing it, of course, is countering the (good) intention...

In the meantime Jack's advice will help you.

Regards,

---rony

No. But you may be missing some stuff. BSF is a framework. The Engines 
link into the Framework.

Suggestion: sit down and read the BSF documentation for an hour or two :)

Page 1 of the BSF manual says:

    The two primary components of BSF are the |BSFManager| and the
    |BSFEngine|.

    The |BSFManager| handles all scripting execution engines running
    under its control, and maintains the object registry that permits
    scripts access to Java objects. By creating an instance of the
    |BSFManager| class, a Java application can gain access to scripting
    services.

    The |BSFEngine| provides an interface that must be implemented for a
    language to be used by BSF ...

I guess it is failing at the following code location in BSFManager.java

private Log logger = LogFactory.getLog(this.getClass().getName());

Hi Raza,

also, make sure that the Java statement is syntactically correct.

In your example you obviously want to execute the following Java

read:

	Object o = manager.eval("java","",0,0,"return (2==2);");

Site with AJAX load time analysis

2008-04-28T00:22:14Z

Hi,

I've been using jmeter to run some page load times for a few sites, but I've
run into a bit of a problem. Basically I want to get stats of how long whole
pages (page + resources) take to load over a period of time, with differing
number of users hitting the site.

I realise that there is the 'Download all HTML content' checkbox which will
do just this, but unfortunately it does not execute all the AJAX components
of the website (of which there are many - basically the whole site). So this
gives a deceptively low impression of the load time of pages.

When you record a page load with the HTTP proxy (to capture all the
resources, including the AJAX elements), and then run a test with it - it
seems to treat each resource separately in a Aggregate / Summary report, so
its difficult to get this sort of information (many of the images / AJAX
resources all run the same server-side script so appear as the same entry in
the report when they are in reality different resources [e.g. "image.php"
where the requests were image.php?id=1234 and image.php?id=5678]).

Is there any kind of mechanism to roll-up/group a set of resources into one
transaction element to achieve this sort of reporting?

Oh and is there an out-of-the box mechanism to limit bandwidth of what
jmeter allows each 'user' to use?

Many thanks.

Accessing classes defined in a script

2008-02-18T09:53:17Z

Hi,

I am pretty new to BSF and I ran into a problem.
I have a java class "JavaClassA" and I want to extend it in a script, 
Groovy or BeanShell.

...
public class BSHClassA extends JavaClassA {
    public run() {
       ...
    }
}

Without BSF and with Beanshell only, I was able to "source" the script 
and access the class BSHClassA  via Beanshells' classmanager and 
instantiate it in Java like this:
...
beanShell.source(scriptFile);
classLoader = beanShell.getClassManager();
Class clazz = classLoader.classForName( bshClass );
bshObj = (JavaClassA) clazz.newInstance();

How do I instantiate a class defined in a script language via BSF?
I don't know what to do after:

theBsfManager.exec(scriptLang, scriptFile, 0, 0, 
IOUtils.getStringFromReader(scriptFileReader));

Thanks in advance

Mirko

As you'll see with the chart on the home page, one of our goals with
the site has been to focus heavily on analytics.  We have lots of
graphs and counts, and you're able to use them to watch Apache's
historical growth and each individual project's growth.  Every query
you write gets its own histogram chart.

Another goal has been interactivity.  Every search result screen gives
you lots of ways to refine your search (by sender, list, attachment
type, etc).  Plus we did a lot with keyboard shortcuts.  You can hit
"n" and "p" to move to the next and previous result and "j" and "k" to
move up and down the thread view.  There's a lot of little things like
this.  Plus if your result message includes Office or PDF files
they're in-line interactive too.

http://apache.markmail.org/search/ext:ppt+axis

Another goal has been to focus on community.  We could have launched
MarkMail with 50,000,000 emails from many sources but I think it's
better to start with focus.  In fact, I'll be at ApacheCon and the
Hackathon next week, along with my co-developer Ryan Grimm,
looking for people's suggestions and maybe on the spot adding in a
few of them.  There's also potential to explore some fun one-off
analytics, too.

As part of the focus on communities, we setup MarkMail so it
recognizes that Apache itself consists of many communities.  If you go
to http://apache.markmail.org you search all Apache emails, but if you
go to http://struts.markmail.org then you're auto-limited to just
Struts lists.  Same for tomcat, spamassassin, httpd, and so on.  You
can always limit your search using "list:struts" in your query, but
using the domain handles that a bit more elegantly.

I've been working on this a long time, and I'm so happy to be able to
share it with everyone.  I hope you all find this useful!

Notes on using the site:

* Search using keywords as well as from:, subject:, extension:, and
  list: constraints

* The GUI doesn't yet expose it, but you can negate any search item,
  like -subject:jira.

* You can sort results by date by adding order:date-forward or
  order:date-backward to your query

* Remember to use "n" and "p" keyboard shortcuts to navigate the search
  results

* You're going to want JavaScript enabled

If you'd like to send me private feedback I'm jhunter at apache dot org.

Bugzilla # 41549: Anyone Interested on Doing Some Work on the Jython BSF 2.4 engine ?

2007-10-29T15:04:17Z

Hi there,

in  a request
was made to change the jython engine in BSF 2.4 such that the apply()
method would forward the arguments.

Would there be any takers on doing the necessary work on this?

BSFManager.compileScript should do what you need.

Script validation

2007-10-26T10:06:47Z

Hello all,

I'm a noob currently using BSF to run user entered Groovy script, and potentially
other scripting languages, within a Java application and am looking for a way to
validate the script syntax via BSF before actual execution. Can anyone tell me if
this is possible.

Cheers

Please use JIRA when reporting bugs

2007-08-16T04:48:19Z

Please use JIRA[1] when reporting bugs since it helps a lot to track,
prioritize and assign them so that they will get fixed somewhere down the
wire.

Thanks,

Yes, the question would be whether this consumption can be felt at all,
or - in the other extreme - whether it would render the application  to
be unusable.

Unfortunately, I do not know what architecture/limitation Rhino would
have and if it was possible to invoke it differently, such that one
Rhino instance executes scripts concurrently (e.g. not sure what 
"org.mozilla.javascript.Context" does/allows for) . Maybe one of the
Rhino/Javascript BSF engine creators could help (* @author   Adam Peller
,  * @author   Sanjiva Weerawarana,  * @author  
Matthew J. Duftler,  * @author   Norris Boyd)?

Short of that one would have to study that particular aspect of
Rhino/Javascript, maybe there are even threads on the Mozilla newsgroups
about this topic?

Again, not sure at all what 'global' encompasses. One would need to dig
into the Rhino/Javascript interpreter.

Maybe, you should not be preoccupied too much ?

Having a pool of BSFManagers used to deploy scripts with the help of
Rhino engines, what would be the maximum amount of instances you have to
deal with? Do you have any profilings that you could gather and share
with us?

Re: Issue when run multiple script files simultaneously

2007-07-05T16:58:55Z

Yes, I can do that.

  In fact, at my first round of experiment, I created one new BSFManager every time when I
need to run a script. By doing this the script all run correctly. Essentially, this is similar
to having a pool because they have the pros that each script is executed in its own Rhino
instance, but the cons is that I loaded different Rhino instance for each script runtime,
that could consume more memory. 

  So my question is: What's the final reason of the script interfere with each other when
they are run in different thread but using the same Rhino instance. 

  I looked at the 
  org.apache.bsf.engines.javascript.JavaScriptEngine.java.  It looks that the reason maybe
in the initialize method. Every JavaScriptEngine is initialized with a Scriptable object 'global',
then when the eval() method is called, it's always called using
  cx.evaluateString(global, scriptText,source, lineNo,null);

  But I am not sure what's stored in the 'global', and why finally two scripts interfere with
each other. 

  Is it conceptually correct to use the same 'global' for evaluating different script files?
 And besides the way of using separate BSFManager instance for each thread, is there any way
I still share the same BSFManager and Rhino instance but use different 'global' value for
each thread? Because I am really concerned about the memory issue of instanciating multiple
BSFManager and Rhino engine.

  Thanks

  Linda

How about creating a pool of BSFManager instances and (re-)using the
instances to deploy the scripts such, that each BSFManager instance
serves one script executing in the same thread?
