Hi there,

I'm using Spring 3.0 with WAS 7.0. When processing a request, this code
Code:
javax.servlet.RequestDispatcher rd = request.getRequestDispatcher("/spring/test.action");
rd.forward(request, response);
results in this exception:
Code:
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.IllegalArgumentException: argument type mismatch
at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:656)
…
Caused by: java.lang.IllegalArgumentException: argument type mismatch

      at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:719)
      at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:644)
The key part of my configuration is as follows.

In web.xml,
Code:
<servlet-mapping>

<servlet-name>Spring Dispatcher</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>
In controller class,
Code:
@RequestMapping("/spring/test.action")
I was trying to figure out what causes "argument type mismatch" exception but failed. Does anyone know what might be the cause?

Thank you for your help!
