Grouper Users - Open Discussion List

["Biernath, Jutta" <>]

Hi, Keith,

I had the same problem. In our case it was because there are incompatible 
versions of xercesxxxx.jar and xmlParserAPIxxx.jar used. The reason for this 
can be that there are old versions of these jars on java classpath. In our 
environment however it was the xercesImpl-2.10.0.jar and 
xmlParserAPIs-2.6.2.jar used by grouper itself. They come in the custom 
directory. 

I could solve this by commenting out the following line in bin/gsh.groovy:

# GROUPER_CP=${GROUPER_CP}:${GROUPER_HOME}/lib/custom/*

Nice tool though!



Regards,

Jutta

Betreff: Re: [grouper-users] Error output from groovysh

Keith,

The problem sounds like this one outlined on SO [1].
I'm no Java expert, but I'm going to guess it might be related to your Groovy 
installation.
Can you see if there are xerces jars in your Groovy lib directory?  I'm 
guessing they are causing some kind of type compatibility issue with jars 
bundled with Grouper.

Subject: [grouper-users] Error output from groovysh

All, but probably Bill Thompson,

We installed groovysh yesterday. Very nifty! Unfortunately, every minute or 
so we get an error like the following sent to console when we're running the 
shell:

Apr 06, 2017 2:55:27 PM java.util.prefs.FileSystemPreferences syncWorld
WARNING: Couldn't flush user prefs: java.util.prefs.BackingStoreException: 
java lang.ClassCastException: 
org.apache.xerces.jaxp.DocumentBuilderFactoryImpl cannot be cast to 
javax.xml.parsers.DocumentBuilderFactory

This is with the Groovy version of the shell.

Any suggestions how we'd fix that?

Thanks,
Keith
