http://issues.apache.org/bugzilla/show_bug.cgi?id=39966 Summary: Class Cast Exception inTagHandlerPool Product: Tomcat 5 Version: 5.5.17 Platform: Other OS/Version: other Status: NEW Severity: normal Priority: P2 Component: Jasper AssignedTo: tomcat-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] I have written a Custom tag which extends SimpleTagSupport. I am getting a very spurious error occuring very rarely. If I have a JSP page which is very simple and just uses the custom tag itself then everything works as expected. However in a more complicated application I get the exception below. I am curious under what circumstances does the TagHandlerPool get used instead of just instantiating the tag class directly? Should it be checking to see if it is a SimpleTag and converting it using a TagAdapter on line 116? java.lang.ClassCastException: com.teamphone.common.jsp.image.ImageTag at org.apache.jasper.runtime.TagHandlerPool.get(TagHandlerPool.java:116) at org.apache.jsp.WEB_002dINF.views.default_.authentication.LogonRenderer_jspx._jspx_meth_image_image_0(LogonRenderer_jspx.java:373) at org.apache.jsp.WEB_002dINF.views.default_.authentication.LogonRenderer_jspx._jspService(LogonRenderer_jspx.java:140) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:332) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:672) at org.apache.catalina.core.ApplicationDispatcher.processRequest(ApplicationDispatcher.java:463) at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:398) at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:301) at com.teamphone.common.servlet.http.HttpDocumentFactory$ForwardDocument.writeBody(HttpDocumentFactory.java:329) at com.teamphone.common.servlet.http.HttpDocumentFactory$AbstractDocument.write(HttpDocumentFactory.java:200) at com.teamphone.common.servlet.http.HttpServlet.doRequest(HttpServlet.java:173) at com.teamphone.common.servlet.http.HttpServlet.doGet(HttpServlet.java:100) at javax.servlet.http.HttpServlet.service(HttpServlet.java:689) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:869) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:664) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:80) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684) at java.lang.Thread.run(Thread.java:595) -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
