i am calling my EJB method " transfer(request,destination) " from inside JSP page.



" request " is a HttpServletRequest object

" destiation " is a string



it is throwing following exceptions.....



java.rmi.MarshalException : failed to marshal public abstract void project.upload.Copy.transf
er(javax.servlet.http.HttpServletRequest,java.lang.String) throws java.rmi.RemoteException,j
ava.io.IOException;
nested exception is: java.io.NotSerializableException: weblogic.servlet.internal.ServletRequestImpl
java.io.NotSerializableException: weblogic.servlet.internal.ServletRequestImpl






actually i am trying to uplaod files and in JSP i use tag to select a file inside a form.the logic is this that request object also have the file stream and using

ServletInputStream in = request.getInputStream();



i can get the file stream and then save this stream in a new file




Why it is giving exception and any other way to upload files?



Thanks for THIS....
