Error in using XSL TagLib

[Mullin Yu]

Hi,       I got Tomcat run without any problem, but when I tried to work with XSL TagLib, I got the following error when played with the example.war provided during installation:   ================================================================ Result of the HTML page showed: ================================================================     This page creates several versions of the same table, using the same XML data and XSL stylesheet (so that the output should appear identically), but using different techniques to retrieve the XML data. Display the source of this JSP page (from the examples menu) to see how these techniques are used.   --------------------------------------------------------------------------------   This version of the table was created by reading an external XML document and an external XSL stylesheet.   Error: 500 Location: /tagLib/jsp/Apply.jsp Internal Servlet Error:   javax.servlet.ServletException  at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:399)  at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)  at org.apache.tomcat.core.ServletWrapper.doService(ServletWrapper.java:404)  at org.apache.tomcat.core.Handler.service(Handler.java:286)  at org.apache.tomcat.core.ServletWrapper.service(ServletWrapper.java:372)  at org.apache.tomcat.core.ContextManager.internalService(ContextManager.java:797)  at org.apache.tomcat.core.ContextManager.service(ContextManager.java:743)  at org.apache.tomcat.service.connector.Ajp12ConnectionHandler.processConnection(Ajp12ConnectionHandler.java:166)  at org.apache.tomcat.service.TcpWorkerThread.runIt(PoolTcpEndpoint.java:416)  at org.apache.tomcat.util.ThreadPool$ControlRunnable.run(ThreadPool.java:498)  at java.lang.Thread.run(Thread.java:484)   Root cause: java.lang.NoSuchMethodError  at org.apache.xalan.xpath.dtm.DTM.(DTM.java:222)  at org.apache.xalan.xpath.dtm.DTMLiaison.parse(DTMLiaison.java:197)  at org.apache.xalan.xslt.XSLTEngineImpl.getSourceTreeFromInput(XSLTEngineImpl.java:838)  at org.apache.xalan.xslt.XSLTEngineImpl.process(XSLTEngineImpl.java:552)  at org.apache.taglibs.xsl.ApplyTag.doEndTag(ApplyTag.java:272)  at jsp._0002fjsp_0002fApply_0002ejspApply_jsp_0._jspService(_0002fjsp_0002fApply_0002ejspApply_jsp_0.java:87)  at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:119)  at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)  at org.apache.jasper.servlet.JspServlet$JspServletWrapper.service(JspServlet.java:177)  at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:318)  at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:391)  at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)  at org.apache.tomcat.core.ServletWrapper.doService(ServletWrapper.java:404)  at org.apache.tomcat.core.Handler.service(Handler.java:286)  at org.apache.tomcat.core.ServletWrapper.service(ServletWrapper.java:372)  at org.apache.tomcat.core.ContextManager.internalService(ContextManager.java:797)  at org.apache.tomcat.core.ContextManager.service(ContextManager.java:743)  at org.apache.tomcat.service.connector.Ajp12ConnectionHandler.processConnection(Ajp12ConnectionHandler.java:166)  at org.apache.tomcat.service.TcpWorkerThread.runIt(PoolTcpEndpoint.java:416)  at org.apache.tomcat.util.ThreadPool$ControlRunnable.run(ThreadPool.java:498)  at java.lang.Thread.run(Thread.java:484)   =========================================================       Any ideas?
