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=3D"org.apache.jasper.JspC"=20
classpath=3D"${basedir}/tools/common/lib/servlet.jar;${basedir}/tools/lib=
/jasper-runtime.jar;${basedir}/tools/lib/jasper-compiler.jar"=20
fork=3D"true" dir=3D"${deploy.home}">
      <arg line=3D"-d ${workdir} -webapp web"/>
 </java>

And then I tried a similar thing with jspc :

<jspc srcdir=3D"${deploy.home}/web" destdir=3D"${work.dir}"=20
classpath=3D"${toollib.dir}/jasper-runtime.jar;${toollib.dir}/jasper-comp=
iler.jar;${servletlib.dir}/servlet.jar">
      <include name=3D"**/*.jsp"/>
</jspc>

which also works fine.


I have noticed that jspc has a nested webapp tag, but I didn't get it wor=
king.=20
E.g. I cannot specify it alone, I have to keep "include" tag as well, whi=
ch=20
is somehow strange.

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

<javac srcdir=3D"${work.dir}" destdir=3D"${work.dir}"=20
classpath=3D"${basedir}/classes:${toollib.dir}/Apollo.jar:${toollib.dir}/=
jdom.jar:${toollib.dir}/jspsmartupload.jar:${toollib.dir}/ant.jar:${tooll=
ib.dir}/velocity.jar:${toollib.dir}/commons-collections.jar:${servletlib.=
dir}/servlet.jar"=20
debug=3D"on" />

It looks like tomcat ignores the compiled files, i.e. it doesn't load the=
m=20
faster.
Seems like tomcat somehow recompiles them again, and for some reason it=20
creates more *.class files then when I compiled them with javac.
Anybody knows what does it mean ?


Thanks for the help

Cheers

Matt
