http://nagoya.apache.org/bugzilla/show_bug.cgi?id=5218 org.apache.jasper.JasperException: Unable to compile class for JSP Summary: org.apache.jasper.JasperException: Unable to compile class for JSP Product: Tomcat 4 Version: 4.0.1 Final Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Blocker Priority: Other Component: Jasper AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] This error appears when I was testing Cocoon2 (cocoon-2.0rc2.tar) and add a match in a pipeline section of the file sitemap.xmap with something like this: <map:match pattern=""> <map:generate type="jsp" src="eventos/buscarEventos.jsp"/> <map:transform src="test/Semana.xslt"/> <map:serialize/> </map:match> Basically a JSP that responds with some XML data and use a XSLT to process that XML data. When I try to used it I got an error like this: org.apache.cocoon.ProcessingException: SAXException JspGenerator.generate(): org.xml.sax.SAXParseException: The root element is required in a well-formed document. then I start searching for the cause and execute de JSP normally and Tomcat response was: Incompatible type for method. Explicit cast needed to convert java.lang.Throwable to java.lang.Exception. if (pageContext != null) pageContext.handlePageException(t); ^ 1 error at org.apache.jasper.compiler.Compiler.compile(Compiler.java:284) at org.apache.jasper.servlet.JspServlet.loadJSP(JspServlet.java:546) at org.apache.jasper.servlet.JspServlet$JspServletWrapper.loadIfNecessary (JspServlet.java:177) at org.apache.jasper.servlet.JspServlet$JspServletWrapper.service (JspServlet.java:189) at org.apache.jasper.servlet.JspServlet.serviceJspFile (JspServlet.java:382) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:474) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter (ApplicationFilterChain.java:247) at org.apache.catalina.core.ApplicationFilterChain.doFilter (ApplicationFilterChain.java:193) at org.apache.catalina.core.StandardWrapperValve.invoke (StandardWrapperValve.java:243) at org.apache.catalina.core.StandardPipeline.invokeNext (StandardPipeline.java:566) at org.apache.catalina.core.StandardPipeline.invoke (StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardContextValve.invoke (StandardContextValve.java:201) at org.apache.catalina.core.StandardPipeline.invokeNext (StandardPipeline.java:566) at org.apache.catalina.core.StandardPipeline.invoke (StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardContext.invoke (StandardContext.java:2344) at org.apache.catalina.core.StandardHostValve.invoke (StandardHostValve.java:164) at org.apache.catalina.core.StandardPipeline.invokeNext (StandardPipeline.java:566) at org.apache.catalina.valves.ErrorDispatcherValve.invoke (ErrorDispatcherValve.java:170) at org.apache.catalina.core.StandardPipeline.invokeNext (StandardPipeline.java:564) at org.apache.catalina.valves.ErrorReportValve.invoke (ErrorReportValve.java:170) at org.apache.catalina.core.StandardPipeline.invokeNext (StandardPipeline.java:564) at org.apache.catalina.valves.AccessLogValve.invoke (AccessLogValve.java:462) at org.apache.catalina.core.StandardPipeline.invokeNext (StandardPipeline.java:564) at org.apache.catalina.core.StandardPipeline.invoke (StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardEngineValve.invoke (StandardEngineValve.java:163) at org.apache.catalina.core.StandardPipeline.invokeNext (StandardPipeline.java:566) at org.apache.catalina.core.StandardPipeline.invoke (StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.connector.http.HttpProcessor.process (HttpProcessor.java:1011) at org.apache.catalina.connector.http.HttpProcessor.run (HttpProcessor.java:1106) at java.lang.Thread.run(Thread.java:484) I downloaded the source of Tomcat jakarta-tomcat-4.0.1-src.tar and search for that line and I found it .... so I patch it ( File: org.apache.jasper.compiler.JspParseEventListener.java ) with: writer.println("if (pageContext != null) pageContext.handlePageException ((Exception)t);"); I just add the Cast to an Exception Object. Compile the class and the error disappeared.
