The class required by Guvnor, org.apache.commons.lang.StringUtils, doesn't
exist in 3-3.1.
It has been renamed org.apache.commons.lang3.StringUtils in 3-3.1.

Hi, All
I am using Guvnor 5.4.0 Final with Tomcat 6.0.35. And I wanted to replace
commons-lang2.4 with commons-
lang3-3.1, so I overwrote the commons-lang2.4 jar file in Guvnor's
WEB-INF/lib directory with commons-
lang3-3.1.jar. However an error like follows occured:
Service method 'public abstract long
org.drools.guvnor.client.rpc.AssetService.getAssetCount(org.drools.guvnor.client.rpc.AssetPageRequest)
throws com.google.gwt.user.client.rpc.SerializationException' threw an
unexpected exception: java.lang.NoClassDefFoundError:
org/apache/commons/lang/StringUtils org/apache/commons/lang/StringUtils
I have restarted Guvnor.
Any suggestion will be appreciated, thank you very much.
