RAS with jsp

[neltan]

Hi,
I'm newbaby to CR9 RAS. I'm now testing on the RAS with jsp. I encounter problem with this line:
viewer.processHttpRequest(request, response, application, out);

and get this error:
org.apache.jasper.JasperException: (class: com/crystaldecisions/xml/serialization/XMLObjectSerializer, method: setHandler signature: (Lcom/crystaldecisions/xml/serialization/CrystalSAXParserHandlerV) Incompatible object argument for function call
===========================================================
My Setting:
j2sdk1.4 + tomcat 4.1.12 + win xp

webapp is the sample webapps "xtreme" from crystal report website

RAS running on IIS of same PC
===========================================================
Question:
1. Why fail?
2. When CR9 RAS launch? I can't find much resources from the web? It seems little java developer work on RAS ?

Synopsis

When previewing a report using a Java Server Page (JSP) on a TomCat 4.1.18 web server, the following error message is displayed:
"The server encountered an internal error () that prevented it from fulfilling this request."
The details of the error message indicate that the /serialization/XMLObjectSerializer class has an incompatible object argument for the function call.

Use the latest jar, and problem solved.

=======================================================================
We are now trying the Report Application Server of Crystal Report, it seems good.
We would like to reuse the crystal report, originally design for VB, in the JSP webapps.
