I have a webapp running on Tomcat 6.0.16 under Red Hat 4 Linux (version 2.6.22.7).
99% of the time it runs fine. But every once in a while, one of the JSP pages (that was working just fine) will stop working. When I try to access that JSP, Tomcat gets a JasperException, with this root cause exception: java.lang.ClassNotFoundException: org.apache.jsp.index_jsp java.net.URLClassLoader$1.run(URLClassLoader.java:200) java.security.AccessController.doPrivileged(Native Method) java.net.URLClassLoader.findClass(URLClassLoader.java:188) org.apache.jasper.servlet.JasperLoader.loadClass(JasperLoader.java:134) org.apache.jasper.servlet.JasperLoader.loadClass(JasperLoader.java:66) org.apache.jasper.JspCompilationContext.load(JspCompilationContext.java:598) org.apache.jasper.servlet.JspServletWrapper.getServlet(JspServletWrapper.java:144) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:329) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:337) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:266) javax.servlet.http.HttpServlet.service(HttpServlet.java:803) When this happens, I reboot Tomcat, and then the JSP works again. (This would seem to rule out the possibility that someone is modifying the JSP and causing it to not be compileable.) If I had to make a wild guess, it seems that perhaps Tomcat has an internal cache of class files, which becomes corrupt. Has anyone else seen this? Is there a fix or workaround? Thanks, Mike
