Hi alok,
this error you are getting while accessing MWS using custom login page or everytime you get it when you restart your server?
Whether your server is coming up and running? Are you able to login using MWS default login page using ‘Administrator’ and manage?

Regards,
Vikas

alokranjit_samal · November 13, 2013, 3:53pm

Hi Vikas,

No the server is not starting. Everytime I try starting the server through cmd, it shows this NullPointerException and disappears. Unable to access the login page.

As part of quick resolution of the issue, we have created a new server instance in our development environment. Still we are trying to make the old instance work. Any solution?

Thanks & Regards,
Alok Ranjit Samal

Dear Samal,
I have the same issue, tried many ways but still could not able to resolve. Please see Unable to start MWS -- java.lang.NullPointerException - webMethods - Software AG Tech Community & Forums thread for more help, let me know if you found any solution.

Thanks,
Anil.

The original issue might be caused by some changes on the database side.

Another option might by the applicatioon of fixes to the MWS or the Shared components.

One way to check might be to apply the latest SCG_x_DataDirect42_Fix and retry.

Most likely MWS will not complete its startup sequence as it is unable to locate the configuration data due to the protocol error.

Regards,
Holger
