Tomcat Web Server 3.1 bug

[Vishal Batra <vi...@rediffmail.com>]

hello ,

i am working on a web based application using JSP on Tomcat Web Server. 
Other tools used are JavaMail 1.1.
I am getting a runtime exception which i have tried to solve but am 
unable to do so. So i have come to u for help.

I have traced out the location where i get this error.

I have a jsp mailTest.jsp which calls method mailUserAboutLoginCreation( 
) of TeamshareMailBean.class
This method accepts 5 String parameters. This method calls method 
sendMessage() of MailGenericBean.class.
It is here that I get a problem. The following code causes the problem ( 
of sendMessage() ).

           try
           {
               message = new MimeMessage( session ) ; // message is 
object of javax.mail.Message class
                                                                         
          // session is an object of javax.mail.Session class
           }
           catch( Exception e )
           {
               outputWriter.write( "CATCH : Exception while creating 
Message object : " + e ) ;
           }
           finally
           {
               outputWriter.write( "FINALLY : Exception while creating 
Message object : " + message ) ;
           }

When the above code executes the 'message' object is not instantiated. 
The 'catch' block is not executed while the 'finally' block is 
executing. The code which follows the 'finally' block is not executed.

After this the HTML part of mailTest.jsp which lies above the 
TeamshareMailBean.mailUserAboutLoginCreation( ) appear on my browser 
followed by the exception. Here is the output ( in italics) :

Unfortunately, the above code is giving problem only with Tomcat Web 
Server, version 3.1 and not with version 3.2.1.

In my lab we use Tomcat Web Server 3.2.1 but our Application Service 
Provider uses Tomcat Web Server 3.1

It is working very fine in my lab but not in the uploaded version.

Kindly suggest a solution
