Crystal Reports 2013 java-error "java.lang.ClassCastException: class com.crystaldecisions..." when promoting

[Former Member]

Hi,

when promoting "Crystal Report 2013" report (with data connectivity BW MDX Query) from BO DEV to BO PROD with BO Promotion Mgmt (LCM), we get the following error message in LCM jobs history:

Resolution Status=Overwritten, Dependency Status=All the required dependencies are included.,

Commit Status=Commit attempted and failed.,

Promotion Status=Failure : Object promoted. Update failed.

Error: java.lang.ClassCastException: class com.crystaldecisions.sdk.occa.report.lib.ByteArray:java.net.URLClassLoader@1d634758 incompatible

with class com.crystaldecisions.sdk.occa.report.lib.PropertyBag:java.net.URLClassLoader@1d634758

The report itself is present on BO PROD, but the overwrite (BW DEV MDX Query-> BW PROD MDX Query) is not applied, so report connectivity still points to the BW Query on the development system 😞 .

Moreover, the overwrite itself is detected when the job is "test promoted" ("active overwrite").

Before, we successfully were able to transport crystal reports 2013 with overwrite (the connection then pointed to BW PROD). No idea yet what suddenly changed that...

Any ideas what causes the error and what can fix it (no posts found, no SAP note, google also no hits)?

Best regards

Update:

After more investigation, it looks as if the BO Server "CrystalReports2013ReportApplicationServer"

from time to time has an issue - not only when promoting, but also when viewing publications that contain Crystal Report documents or when executing them, the java class error or similar issue is thrown.

Did sb face similar behaviour and knows what is the root cause for "CrystalReports2013ReportApplicationServer" not working probably and throwing the java-class error? - it was running fine for several months, now, the class error showed up twice in one month.

We need to find out what is causing the issue (aleady checked tomcat and BO-logfiles...).

Best Regards

Florian
