Problems deploying struts application

Hi, I am having two small problems deploying a struts application. I haven't tracked down the problem entirely, but I was wondering if anyone else had seen these problems and had a quick fix. When I attempt to deploy my application, I get two different exceptions in the error log. The first error is "java.lang.NoClassDefFoundError: org/apache/log4j/Layout". I am sure that I am using a different version of Log4j than JRun uses. I looked on the JRun web site, and tried to put the following in WEB-INF/jrun-web.xml: <jrun-web-app>     <load-system-classes-first>false</load-system-classes-first> </jrun-web-app> However, this did not appear to cause any differences. (I got this tip from http://www.macromedia.com/support/documentation/en/jrun/4/releasenotes_4 _updater6.html) The second error repeats four or five times: 10/05 19:23:37 error Exception parsing the TLD null : The tag function on line 14 is not a valid TLD element [2]jrun.jsp.compiler.JRunTagLibraryInfo$InvalidTLDElementException: The tag function on line 14 is not a valid TLD element I suspect this error is occurring because of problems with the struts TLD files (i.e. struts-bean.tld, etc.). Has anyone else run into these problems? Thanks for your help; if I find the problem or the solution independently, I'll be sure to post a followup. I should note that the war file deploys without any problems on Tomcat 5.5.7. Regards, Sam Greenfield Manager of System Development Sports Illustrated
