Trying to display the detail for one document --> error: see below:

Minor Environment Exception
A minor environment problem occurred in the application program. Normally this problem is solved after a retry of the operation.
Error message: 002: Parameter no longer meaningful. Either session expired or you have pressed the Back button.
Help message: Either we have a problem in our linking or you have pressed the Back button. This will not work in all cases.
Exception class: com.softwareag.xtools.xapplication.jsp.NavigationException

*************************************************
Any help is welcome!
The Tamino Schema is added to this message!
Web-Crawler-schema.tsd (4.17 KB)

I copied the old version of the JSP search, list and view from X-application 0.6 and modified the bdm:module tag, then the problem was solved.
But I don’t know why it occurs with the generated files.

Hi Reto,

please check, if you have the correct URL. Is it possible that there is a upper/lower case problem in the path (e.g. http://localhost:8080/Crawler instead of http://localhost:8080/crawler)?

You can make sure that Tomcat does not accept that mismatch if you add in /conf/server.xml (and serverXapp8081.xml)
<SimpleMapper1 ignoreCase=“false”/>
