pitstop [https://community.jboss.org/people/pitstop] created the discussion "create a ESBServiceWorkItemHandler" To view the discussion, visit: https://community.jboss.org/message/819415#819415 -------------------------------------------------------------- Hi all, I need to create a ESBServiceWorkItemHandler to create a wf task  that invokes a service on jbossesb. I have two different servers. The server one hosts BRMS, the second server hosts SOA-P where there the esb to invoke. I deployed my WorkItemHandler implementation in business-central-server.war.  When ESBServiceWorkItemHandler is invoked I cannot instanziate the service invoker and this exception is thrown:

WEB-INF/lib of  business-central-server.war  a jar containing the workitemhandler implementation and these files: jbossesb-properties.xml, jndi.properties and META-INF/uddi.xml In WEB-INF/lib of  business-central-server.war  there are also the jbossesb-*.jar  , juddi-client-*.jar and uddi-ws.*.jar. The other libraries to invoke an external client are deployed under <server-name>/lib These client with the dependencies described is successfully invoked from my standalone jbds environment.  Where is the best place to deploy lib for my esbclient?
