In a JSF application debugging on Websphere Application Server 7, if you click on a commandLink control a runtime org.apache.jasper.el.JspMethodNotFoundException will occur.
When clicking a hyperlink that was created by a JSF commandLink control, an error is displayed in the page.
The JSP and JSF implementation shipped with this version of Websphere Application Server works in such a way that the debugger cannot intercept the clicking of a commandLink. This prevents proper execution of the EGL function bound to the control.
This is only for the version 7 series of Websphere, and only when the server is started in debug mode. All versions of Rational Business Developer that support Websphere Application Server 7 are affected.
Resolving the problem
There is no solution to this problem. You can either use a different version of Websphere Application Server, like version 8, or you can change your commandLink control to some other JSF control like a button.
