Fiona needs help: Big HTTP 500-Problem with JavaBeans / SpringFrameWork

[Fiona]

Dear All!
I have the following problem:

We have a JavaBeanApplication that uses an very old version of the Spring framework.

The application runs correctly on multiple machines of our customers.

On another server I can start the application and also operate. The configuration is the same. It uses the same JDBC driver etc. etc.

But after a few minutes I get after clicking on any button a HTTP500 error! See below.

A TimeOut of the SpringFramework?

What can that be?
For a tip, I would be very, very, very grateful!

Best greetings
Fiona

Hello Fiona

Can you post the complete error stack trace?

javax.servlet.ServletException: ModelAndView 
[ModelAndView: materialized View is [null]; model is {}] neither 
contains a view name nor a View object in servlet with name 'springapp'

Seems the model is not filled or created, perhaps in your new server can't server some resource?

Hi Manuel.
Thanks for your reply! I have only the complete error message from
our customer. I posted this err message complete. On the customer machine
is no javabeans develop environment installed. On our development environment with javabeans - the error ist not exist.

What I could offer you: Apache logfile ?

Thanks for your help.

Best regards
Fiona

Hello Fiona

But after a few minutes I get after clicking on any button a HTTP500 error! See below.

Such button trigger or call some controller?, If yes post the source code

What I could offer you: Apache logfile ?

Yes, because even if the error appear to the client side, it was due by a problem from the server side

BTW I hope your client are calling to your new server, and your new server has the same access and privileges than your first server (JDBC driver, DB etc), the worst situation could be that since you copy the project from the old to a new server, the project are assuming to work with some paths that couldn't exists in your new server, and of course access the same DB

Best Regards
