I am trying to create an ant task to compile JSPs. Here are the excerpts from the build.xml related to the task:

....

<fileset dir="${java.home}/lib">
  <include name="tools.jar"/>
</fileset>

<java classname="weblogic.jspc" fork="yes">
  <classpath refid="weblogic.jsp.classpath" />

  <sysproperty key="weblogic.jsp.windows.caseSensitive" value="false"/>

  <arg line="-forceGeneration -keepgenerated -compileAll -webapp ${jsp.src.dir} -d ${jsp.generated.src.dir}"/>
</java>

When I try to run wl.jsp.generate task, I get:

wl.jsp.generate:

 [java] [jspc] warning: expected file /WEB-INF/web.xml  not found, tag

libraries cannot be resolved.

 [java] [jspc] Overriding  default descriptor option 'keepgenerated' with

value specified on command-line 'true'

 [java] Exception encountered while compiling

C:\workspace\smcmw\smcmw_browser\jsp\smcesearchprogress.jsp [java] java.lang.NoSuchMethodError: javax.servlet.jsp.tagext.TagAttributeInfo.(Ljava/lang/String;ZLjava/lang/String;ZZLjava/lang/String;ZZLjava/lang/String;Ljava/lang/String;)V

 [java]  at weblogic.jsp.internal.jsp.tag.TagAttrInfoEx.read(TagAttrInfoEx.java:86)

Looks like it fails because it can't find WEB-INF/web.xml file and tag libraries. How can I fix this?
