Re: useBean and jspc problems under Tomcat 5.0.21

[Jason Novotny]

   From Tim's mail, it looks like it's vendor specific, and for 
optimization reasons you can no longer do this-- which I think stinks, 
but oh well. Frankly, I wish Jakarta projetcs could be more consistent. 
In Pluto for example they focus on correctness and not on optimzations, 
but now in Tomcat I see it's the other way around :-(

Hello,

I have problem with jspc and useBean under Tomcat 5.0.21
I code jspc target into my build.xml which works good under Tomcat 4 
but not under Tomcat 5.
There is my ant target :

 <target name="compile_with_jspc" depends="prepare_with_jspc" 
description="Compile Java sources">

   <antcall target="compile_javabeans"/>
   <!-- JSP precompilation -->
   <taskdef classname="org.apache.jasper.JspC" name="jasper2" >
     <classpath refid="compile.classpath"/>
   </taskdef>
   <jasper2 validateXml="false"
            verbose="99"
            package="com.lc.jspc"
            uriroot="${web.home}"
            webXmlFragment="${build.home}/WEB-INF/generated_web.xml"
            outputDir="${build.home}/WEB-INF/src/com/lc/jspc" />
   <javac srcdir="${build.home}/WEB-INF/src"
          destdir="${build.home}/WEB-INF/classes/"
          debug="${compile.debug}"
          deprecation="${compile.deprecation}"
          optimize="${compile.optimize}">
     <include name="**/*.java"/>
     <classpath refid="compile.classpath"/>
   </javac>
   <delete dir="${build.home}/WEB-INF/src"/>
   <loadfile property="webinc.xml" 
srcFile="${build.home}/WEB-INF/generated_web.xml"/>
   <copy file="${build.home}/WEB-INF/webtoken.xml" 
tofile="${build.home}/WEB-INF/web-full.xml">
     <filterset>
       <filter token="WEB_JSP_XML" value="${webinc.xml}"/>
     </filterset>
   </copy>
   <delete file="${build.home}/WEB-INF/generated_web.xml"/>
   <delete file="${build.home}/WEB-INF/webtoken.xml"/>

   <move file="${build.home}/WEB-INF/web-full.xml" 
tofile="${build.home}/WEB-INF/web.xml"/>

 </target>

There is the source :
               ...
               <jsp:useBean id="barreNav" scope="request" 
class="com.lc.beans.basic.BarreNavigation"  />
               ...

the BarreNavigation have of course a no-arg constructor as you said.

There is the exception :

org.apache.jasper.JasperException
org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:39) 

org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:357) 

org.apache.jasper.compiler.ErrorDispatcher.jspError(ErrorDispatcher.java:141) 

org.apache.jasper.compiler.Generator$GenerateVisitor.visit(Generator.java:1229) 

etc ....
