Hi, Oleg

Please refer to this link
(http://xml.apache.org/xalan-j/commandline_xsltc.html#trax) for
information.

You can use the following sample code for your purpose:

TransformerFactory tf;
tf.setAttribute("use-classpath", "true");
tf.setAttribute("translet-name", "myTranslet");
tf.newTemplates(new StreamSource());

You need to put your translet jar on your classpath. If the "use-classpath"
attribute is set to true, the Templates object is created from the translet
instead of the input Source object. Hence we can pass in an empty
StreamSource to the TransformerFactory.newTemplates() call.  Also note that
you have to provide the name of the translet by setting the "translet-name"
attribute.

Oh I think I know where the confusion is.

I don't want to ship stylesheets along with translets. That's all. I just
want to ship translets, xalan and xsltc, but not XSL stylesheet files.

Am I making any sense ?

Oleg

Then you can  instruct users to have xalan.jar
from somewhere else.  They also can use Java 1.4 JDK (xml.jar)
but the IBM JDK has only the interpretive XSLT processor.
I am not sure if SUN JDK has XSLTC.

I don't have a problem with the translet referring to xsltc processor
classes.

I just don't want to ship the XSL itself along with the translet.

Is it possible to do something like:

FooTranslet foo=new FooTranslet();
foo.transform(source, result);

?

Kind regards,
Oleg

I am not sure I understood your question completely.
As far as I understand you want just take a compiled xsl file (translet).
and use it in your  application. It is not possible because the translet
has references
to XSLTC processor classes.The translet is just a binary representation of
the xsl file
which can be processed by the XSLTC.

Ah, here is the problem.

I am not going to ship the XSL itself, only the classes.

In other words, Templates translet = tFactory.newTemplates(new
StreamSource(xslInURI)); will fail because xslInURI is nonexistent.

I need it to go directly to the class...


Any thoughts ?

Oleg

You can take a look at
http://xml.apache.org/xalan-j/xsltc_usage.html
I think you will find an answer to your question  in
XSLTC TransformerFactory attributes
(attribute use-classpath ).

                                       Java


Dear Distinguished Colleagues:

I need to package my XSLs as precompiled translets.

However, I can?t figure out how to actually use the precompiled translets
(load the class, instantiate and use) from Java.

I am using the latest Xalan-J. Any thoughts, and code fragments are greatly
appreciated.


Regards,
Oleg
