HTTP JVM: com.ibm.xsp.exception.EvaluationExceptionEx: Error while executing JavaScript action expression
We are using beans and expression language on our XPage and we get the above error from time to time, can anyone tell us if there is an easy way to find out which page is causing this and more importantly where in code? We are having to use trial and error methods and having to resort to remove code from page in order to find out where the problem is, which is not the most efficient way to do this.
回答1:
Please check the XPages log files in the IBM_Technical_Support folder in the data directory in order to get more details on the error such as what xpage gave the error and specific details on the error.
If you can not get to the XPages log files on the server directly, then use XPages Log File Reader from OpenNTF to get easy access to the log files from a browser.
Like Fredrik Norling I will also recommend the XPages OpenLog Logger by Paul Withers as a solution to generating error log files automatically.

I would implement Paul Withers XPages Openlog implementation with the phase listening bean and error page. That will help you find the problem. And if you deploy it as an osgi then you only have to set the error page, some xsp properties and add the bean to the faces config file on each database to point it to a central openlog error database.
