Using weblogic.jspc

Question

We are trying to use weblogic.jspc for precompiling the jsps in our application. Following the ANT task for doing the same.
          <target name="runJspc" depends="runAssembler">
               <path id="jspc.path.id">
                    <path refid="class.path"/>
                    <fileset dir="${weblogic.gws.app}/APP-INF">
                         <include name="**/*.jar"/>
                    </fileset>
               </path>     
          <java classname="weblogic.jspc" fork="yes" failonerror="yes">
                    <classpath refid="jspc.path.id"/>
                    <arg line="-webapp ${weblogic.gws.app}/web -compiler ${javac.exec} -classpath ${gws.cl} -compileAll -d ${weblogic.gws.app}/web/WEB-INF/classes -depend -k -keepgenerated -verbose -verboseJavac"/>
               </java>
          </target>
          For some reason, this target runs forever, without printing any logs or anthing. It simply hangs at "runJspc :".
          To dig into details, I modified the target as follows :
          <target name="runJspc" depends="prepare">
          <path id="jspc.path.id">
          <path refid="class.path"/>
          <fileset dir="${weblogic.gws.app}/APP-INF">
          <include name="**/*.jar"/>
          </fileset>
          <pathelement path="${weblogic.gws.app}/web/WEB-INF"/>
          </path>
          <java classname="weblogic.jspc" fork="yes" failonerror="yes">
          <classpath refid="jspc.path.id"/>
          <arg line="-d ${weblogic.gws.app}/web/WEB-INF/classes -classpath ${gws.cl} -compiler ${javac.exec}" />
          <arg value="-k" />
          <arg value="-compileAll" />
          <arg value="-depend" />
          <arg value="-verboseJavac" />
          <arg value="${weblogic.gws.app}/web/retail/jsp_app/home/ft_home.jsp"/>
          <jvmarg line="-Xms512m"/>
          <jvmarg line="-Xmx512m"/>
          </java>
          </target>
          Now it throws below error & stops.
          runJspc:
          [java] [jspc] warning: expected file /WEB-INF/web.xml not found, tag libraries cannot be resolved.
          [java] <Apr 14, 2005 11:49:19 AM PDT> <Warning> <HTTP> <BEA-101181> <Could not find web.xml under WEB-INF in the doc root: ..>
          Is there any way to resolve one of the above two problems ?

Hi Arun,
          It seems that in the second ant target, you decide to compile just a single jsp, while in the first you were trying to compile the complete jsps in a application.
          But in the second target, you forgot to mention -docroot / -webapp target. As a result, the specific error!!.
          To actually debug the first target, try running the program first on commandline , using weblogic.jspc directly passing the arguments.
          This way , you would have a better control over the target, and may be able to isolate the issue easily.
