Troubleshoot: User attempt to sign on to WebSphere Commerce tools page fails
After applying a WebSphere Commerce fix pack or installing a WebSphere Commerce feature pack, you attempt to sign on to a WebSphere Commerce tools page and the sign on fails with a NumberFormatException.
Problem
You complete one or more of the following tasks:
- Install a fix pack, to the server or development machine.
- Apply a fix pack to the WCS instance.
- Install a feature pack to the server or development machine.
After completing the task, you open a WebSphere Commerce tools page and attempt to sign on. The sign on fails and an error, similar to the following, is logged in the SystemOut.log file:
CMN0409E: The following error has occurred during processing: "java.lang.NumberFormatException: For input string: "false"".java.lang.NumberFormatException: For input string: "false" at java.lang.NumberFormatException.forInputString(NumberFormatException.java:63)
Solution
Close any Web browser windows that you are using for the sign on attempts. Open a new Web browser window and attempt the sign on again.
