Pinned topic Class Cast Exception

‏2012-05-14T17:35:25Z |
I am getting a Class cast Exception.I am using JSR 286 portlets.
I was trying to migrate the code from Portal 6.1 to Portal 7.0
It was working fine on Portal 6.1

Message : com.ibm.wps.pe.pc.waspc.filter.impl.RenderResponseWrapperImpl incompatible with javax.servlet.http.HttpServletResponse
java.lang.ClassCastException: com.ibm.wps.pe.pc.waspc.filter.impl.RenderResponseWrapperImpl incompatible with javax.servlet.http.HttpServletResponse
Any idea how I could resolve the same?

    Please post the full stack trace. Also, please indicate how this exception involves the use of web services or schemas.
    Exception occurs at below line
    StateManagerService psms = URLHelper.getPortalStateManagerService((HttpServletRequest) request, (HttpServletResponse) response);

    /**
    * returns the portal state manager.
    *
    * @param request
    * @param response
    */
    public static StateManagerService getPortalStateManagerService(
    final HttpServletRequest request, final HttpServletResponse response) {
    final StateManagerService service;
    try {
    // get the request-specific service from our home interface
    service = getPortalServiceHome().getPortalStateManagerService(
    request, response);
    return service;
    } catch (Exception e) {
    // error handling
    e.printStackTrace();
    throw new RuntimeException(e);
    }
    }
    Below is the stacktrace:

    Thanks. It looks like you've posted to the wrong forum. This forum is for questions regarding Web Experience Factory (WEF). I don't see any WEF classes in the stack trace below. I'd suggest posting to a Portal specific forum; you'll get a better response that way. I'd also suggest investigating the use of WEF to develop your portlets. It could make your portlet development efforts much easier.
