[rules-users] ODP: Loading packages from KnowledgeAgent and Guvnor 5.1

Thanks for the quick answer Esteban. I checked the jars on both my client side and in the webapps\drools-guvnor\WEB-INF\lib of the guvnor install and they're both: drools-core-5.1.1.jar (I even put the same jar myself to make sure). I've also tried to change the value of private static final long serialVersionUID = 510l; in both drools-5.1.1-src\drools-core\src\main\java\org\drools\rule\Package.java and DialectRuntimeRegistry.java but when I do this, the local class incompatible: stream classdesc serialVersionUID = 5308493362083281112 changes as well. I'm sure there is something silly I must be doing on my side, but I cannot find what.

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX Esteban Aliverti - Developer @ http://www.plugtree.com - Blog @ http://ilesteban.wordpress.com 2010/10/7 Pierre de Leusse <pdl(a)agh.edu.pl&gt; Hello everyone, I've deployed Guvnor as a war in Tomcat and I'm trying to load a drools example (drools-5.1.1-src/drools-examples/drools-examples-brms/mortgage-example/mort gage-sample-repository.xml) as a package into a KnowledgeAgent using the code shown there (http://pastebin.com/TvJn9PeQ). I get a few exceptions including: java.io.InvalidClassException: org.drools.rule.Package; local class incompatible: stream classdesc serialVersionUID = 400, local class serialVersionUID = 510 (full trace available at http://pastebin.com/fRvRMtfR). I've tried several things, including checking the serialVersionUID of org.drools.rule.DialectRuntimeRegistry and org.drools.rule.Package as the jiira (https://jira.jboss.org/browse/BRMS-320?page=com.atlassian.jira.plugin.syste m.issuetabpanels%3Acomment-tabpanel#issue-tabs) suggests, but no luck. My code may be buggy and I would welcome corrections/suggestions. All the best, Pierre _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
