Hi,
I am having problems using struts (and tiles) with
JBoss-3.0.3_Tomcat-4.1.12.
My application uses the following in the struts-config.xml file.
<plug-in className="org.apache.struts.tiles.TilesPlugin" >
<set-property property="definitions-config"
value="/WEB-INF/tiles-defs.xml"/>
<set-property property="definitions-debug" value="0" />
<set-property property="definitions-parser-details" value="0" />
<set-property property="definitions-parser-validate" value="true" />
</plug-in>
The tiles-defs.xml file contains the following (cut down):
<tiles-definitions>
<definition name="deployer.rootlayout" path="/layouts/root_layout.jsp">
<put name="docRoot" value="../" />
<put name="titleString" value="Welcome to ..."/>
<put name="topBanner" value="/include/banner.jsp"/>
<put name="lowerBanner" value="/include/lowerbanner.jsp"/>
<put name="content" value="/secure/home_content.jsp"/>
<put name="footer" value="/include/footer.jsp"/>
</definition>
I have traced the error down to the class loader being used by
commons-digester, when it creates the XmlDefinition class. It does not seem
to be the class loader I would expect for my web app, i.e. the
WebappClassLoader. Should the digester be set to use the
Thread.currentThread().getContextClassLoader()?
The CL I get is:
org.jboss.mx.loading.UnifiedClassLoader@17e4dee{ url=file:/E:/My
Projects/EvoDev/jboss-3.0.3_tomcat-4.1.12/server/evo/tmp/deploy/tomcat-4.1.x
/server/lib/commons-digester.jar/79.commons-digester.jar }
The struts.jar is definitely in the WEB-INF/lib dirctory.
The error is as follows:
