Startup.bat calls catalina.bat which calls tomcat5.exe

bump!

Can anyone explain what are the differences between tomcat5.exe and
startup.bat?

cheers,

Hi,

We're trying to instrument a war file using Cobertura, and gather the
coverage details when deployed and used under Tomcat.

Below is a thread from the Cobertura list - I'm having problems when I
run tomcat5.exe (which we use in our product) with the instrumented jar.
In this mode, Cobertura saves the instrumented data when the web server
is shutdown.  If I run tomcat using startup.bat, everything works great.
With tomcat5.exe, no data is saved when tomcat shuts down.

Does anyone know what is causing this, and how I might work around it?

cheers,

David

                                       instrumented war










This code runs during Cobertura initialization:

 private static void initialize()
 {
  // Hack for Tomcat - by saving project data right now we force loading
  // of classes involved in this process (like ObjectOutputStream)
  // so that it won't be necessary to load them on JVM shutdown
  if (System.getProperty("catalina.home") != null)
  {
   saveGlobalProjectData();

   // Force the class loader to load some classes that are
   // required by our JVM shutdown hook.
   // TODO: Use ClassLoader.loadClass("whatever"); instead
   ClassData.class.toString();
   CoverageData.class.toString();
   CoverageDataContainer.class.toString();
   FileLocker.class.toString();
   HasBeenInstrumented.class.toString();
   LineData.class.toString();
   PackageData.class.toString();
   SourceFileData.class.toString();
  }

I'm wondering if catalina.home is not set when you run as a service?

Hi John,

I see cobertura.ser in the ...\tomcat\bin dir getting updated on startup
(timestamp changes) and log shows it found it too.  Just not on
shutdown.
Delay doesn't help.

If you could look for tomcat special case I'd appreciate it.

cheers,

David

It might be due to a different working directory while running as a
service.  Unless you are starting the tomcat jvm while passing in the
java property that tells where the cobertura.ser file is, the file will
end up in the working directory.  I would search the entire hard drive
for a cobertura.ser file.  If you see two, it may be that one was
written by the service.  That would be the working directory.

The other thing is that I would try putting in a delay of about a minute
before calling cobertura-report just to give the java process enough
time to exit.

The other thing is that I do remember some kind of special case code for
tomcat.  I can look for that if the other two things above do not help.

Another thing is that are you sure the instrumented war is in use when
you start it up as a service?

Thanks!  That works - I'd overlooked it.

However, I am running into an issue with Tomcat not updating the
cobertura.ser when it shuts down.  We install it as a service, and when
the service is stopped, nothing gets updated.  Same thing if I start it
from the command line using tomcat5.exe.  However, if I copy the other
files across in the bin directory and start it using "startup.bat", it
does update cobertura.ser.

We'd like to run our acceptance tests on as close as install as
possible, so we'd like to avoid the last option if possible.  Does
anyone know why the service doesn't update the ser file?

cheers,

David

Cobertura 1.8 has support for instrumenting a war file.   Try creating
the
war, then instrumenting it.

I'm not sure this has been tried with maven though.

Subject: [Cobertura-devel] creating instrumented war

Hi,

I'm trying to create an instrumented war file that I can deploy and run
tests against.

I'm using maven, so I am calling the cobertura:on goal in the plugin.
However, this only instruments the non-interface classes, and so when I
jar up this directory, it doesn't contain any interfaces.

I'm trying to avoid having to copy the instrumented files over the
non-instrumented ones to get all the files I need.

Is there a way to get cobertura to include the interface classes (I
understand they're not instrumented, but I would have thought it would
make sense to take a set of java classes and produce a copy of those
classes where all the classes exist and the non-interface classes are
instrumented)?

cheers,

David
