RequestDispatcher forword
Hi all,
I have a web app that generates an exception in the web browser:
Code:
exception
org.apache.jasper.JasperException: Unable to compile class for JSP:
Stacktrace:
org.apache.jasper.compiler.DefaultErrorHandler.javacError(DefaultErrorHandler.java:85)
org.apache.jasper.compiler.ErrorDispatcher.javacError(ErrorDispatcher.java:330)
org.apache.jasper.compiler.JDTCompiler.generateClass(JDTCompiler.java:435)
org.apache.jasper.compiler.Compiler.compile(Compiler.java:298)
org.apache.jasper.compiler.Compiler.compile(Compiler.java:277)
org.apache.jasper.compiler.Compiler.compile(Compiler.java:265)
org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:564)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:299)

org.apache.jasper.servlet.JspServlet.service(JspServlet.java:265)
javax.servlet.http.HttpServlet.service(HttpServlet.java:803)
...
My trace to the java source code says the problem occurs at the following line:
Code:
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
...
RequestDispatcher rd = sc.getRequestDispatcher(url);
System.out.println("[DEBUG]" + url);
if (rd != null)
rd.forward(req, res); // This line generates the exception
else
System.out.println("[DEBUG]rd is null");
}
Other information:
Code:
$ echo $CLASSPATH
.:/usr/share/tomcat5/common/lib:/usr/share/tomcat5/common/lib/servlet.jar
$ java -version
java version "1.6.0"
OpenJDK Runtime Environment (build 1.6.0-b09)
OpenJDK 64-Bit Server VM (build 1.6.0-b09, mixed mode)
Can anyone tell me what I have done wrong? How to make it work? Please.
btw, the same app works in Tomcat6 with SunJDK. I'm using Tomcat5.5 and OpenJDK.
Thanks. |
