Help with JSP pre-compiling

Question

We have a web application using Jboss4.0.5, jdk 1.6 and And 1.6.5, and now we try to do a pre-compiling as part of our build procedure.
That is the first time I am going to do a pre-comp of a major application, which includes about 1700 jsp files.
The directory tree of the application is as follows:
/project
    |--- > /web_pre-comp/pages/jsp ( it contains all the jsp files )
    |----> /web_pre-comp/WEB-INF ( it contains the web.xml file.)
    |----> /web_pre-comp/WEB-INF/tld ( it contains the tld files)
    |----> /web_pre-comp/WEB-INF/src ( it coutains the generated src file from jsp )
    |---->/web_pre-comp/WEB-INF/classes ( it contains the compiled classes once the jsp java files are generated.   )
    |----> build.xml ( the ant script )And there is my build.xml file looks like:
<project>
      <target name="pro.jsp.generate" depens="init">
       <java classname="org.apache.jasper.JspC" fork="yes">
          <classpath refid="tomcat.jsp.classpath"/>
          <arg line=" -d "/>
          <arg value="${jsp.generated.src.dir}"/>
          <arg line="-p"/>
          <arg value="${jsp.package.name}"/>
          <arg line="-webapp"/>
          <arg value="${jsp.src.dir}"/>
       </java>
   </target>
</project>When I was running the ant script, I received such message:
[java] org.apache.jasper.JasperException: The absolute uri: http://www.prounlimited.com/wandappconfig.tld cannot be resolved in either web.xml or the jar files deployed with this application
We do have suh messages included in the web.xml file.
  <taglib>
        <taglib-uri>http://www.prounlimited.com/wandappconfig.tld</taglib-uri>
        <taglib-location>/WEB-INF/tld/wandappconfig.tld</taglib-location>
    </taglib>Any Ideas how to make it working ?
Another side questions is when some java file are created from JSP, I see some "005f" included in the java file name, such as "inc_sup_princing_view.jsp" creats a
"inc_005fsup_005fpricing_005fview_jsp.java" file. Does someone know why this happen ?
Thanks a lot !

We have a web application using Jboss4.0.5, jdk 1.6
and And 1.6.5, and now we try to do a pre-compiling
as part of our build procedure. Hi Charlie,
According to your ant build script you're using Jasper compiler, but your web container is JBoss.
I know that Tomcat uses the Jasper compiler --- but I don't know if JBoss supports Jasper or not. Please check with JBoss if they support Jasper, if not they my support a different pre-compiler.
That is the first time I am going to do a pre-comp of
a major application, which includes about 1700 jsp
files.
The directory tree of the application is as follows:
/project
|--- > /web_pre-comp/pages/jsp ( it contains all
the jsp files )
|----> /web_pre-comp/WEB-INF ( it contains the
web.xml file.)
|----> /web_pre-comp/WEB-INF/tld ( it contains
the tld files)
|----> /web_pre-comp/WEB-INF/src ( it coutains the
generated src file from jsp )
|---->/web_pre-comp/WEB-INF/classes ( it contains
the compiled classes once the jsp java files are
generated.   )
|----> build.xml ( the ant script )And there is my build.xml file looks like:
<project>
<target name="pro.jsp.generate" depens="init">
<java classname="org.apache.jasper.JspC"
fork="yes">
<classpath refid="tomcat.jsp.classpath"/>
<arg line=" -d "/>
<arg value="${jsp.generated.src.dir}"/>
<arg line="-p"/>
<arg value="${jsp.package.name}"/>
<arg line="-webapp"/>
<arg value="${jsp.src.dir}"/>
java>
</target>
</project>When I was running the ant script, I received such
message:
[java] org.apache.jasper.JasperException: The
absolute uri:
http://www.prounlimited.com/wandappconfig.tld cannot
be resolved in either web.xml or the jar files
deployed with this application
Check if the tld folder is visible to the classpath tomcat.jsp.classpath used inside the Ant build file.

</taglib>Any Ideas how to make it working ?
Another side questions is when some java file are
created from JSP, I see some "005f" included in the
java file name, such as "inc_sup_princing_view.jsp"
creats a
"inc_005fsup_005fpricing_005fview_jsp.java" file.
Does someone know why this happen ?
The 005f is expected, it is for internal reference for the pre-compiler, nothing to worry about.
