Hello,

we have got a lot of GEL scripts on customer's production environment, all of them were running without problems, but today are all of them ending with following error:

com.niku.union.gel.GELValidationException; lineNumber: 52; columnNumber: 14; Cannot find Java class 'core' as a tag library. Contact your system administrator.

Have anybody faced this problem? Does anybody have any idea where can be a problem?

EDIT:

in niku/clarity/lib/ I can find file core4j.jar so I think, that it's ok?

 

Thanks in advance,

Martin
