java.lang.IncompatibleClassChangeError in QuickCarRental application

[Former Member]

Hi,

I created the QuickCarRental Application following the tutorials in the help->SAP J2ee Web Applications

then i tried out the tutorials available in the link below for securing Java applications-

http://help.sap.com/saphelp_nw04/helpdata/en/fa/253d408ae01f24e10000000a1550b0/frameset.htm

It was deployed successfully, and when i run it, it prompts me for the user name and password, when the crenditials were entered, it shows the error-

Application error occurred during request processing.

Details: java.lang.IncompatibleClassChangeError:null

Where i would have gone wrong?

Hi Deepika,

Please check if your developer studio version and WAS versions are same. This error occurs generally when there is an incompatibility between the Jar files used.
