Subject Re: JspcC task classpath problem
Date Thu, 27 Jun 2002 17:45:59 GMT

I got it working.
There must have been a problem with how I set the classpath.

First I managed to get working this :

<java classname="org.apache.jasper.JspC" 
classpath="${basedir}/tools/common/lib/servlet.jar;${basedir}/tools/lib/jasper-runtime.jar;${basedir}/tools/lib/jasper-compiler.jar"

fork="true" dir="${deploy.home}">
      <arg line="-d ${workdir} -webapp web"/>
 </java>

And then I tried a similar thing with jspc :

<jspc srcdir="${deploy.home}/web" destdir="${work.dir}" 
classpath="${toollib.dir}/jasper-runtime.jar;${toollib.dir}/jasper-compiler.jar;${servletlib.dir}/servlet.jar">
      <include name="**/*.jsp"/>
</jspc>

which also works fine.


I have noticed that jspc has a nested webapp tag, but I didn't get it working. 
E.g. I cannot specify it alone, I have to keep "include" tag as well, which 
is somehow strange.

Another problem is with using javac to compile generated *.java files :

<javac srcdir="${work.dir}" destdir="${work.dir}" 
classpath="${basedir}/classes:${toollib.dir}/Apollo.jar:${toollib.dir}/jdom.jar:${toollib.dir}/jspsmartupload.jar:${toollib.dir}/ant.jar:${toollib.dir}/velocity.jar:${toollib.dir}/commons-collections.jar:${servletlib.dir}/servlet.jar"

debug="on" />

It looks like tomcat ignores the compiled files, i.e. it doesn't load them 
faster.
Seems like tomcat somehow recompiles them again, and for some reason it 
creates more *.class files then when I compiled them with javac.
Anybody knows what does it mean ?


Thanks for the help

Cheers

Matt
