The default <script-manager> configuration is as following: <?xml version="1.0" encoding="UTF-8"?> <jbpm-configuration>   <process-engine-context>       <script-manager default-expression-language="juel"                     default-script-language="juel">       <script-language name="juel" factory="org.jbpm.pvm.internal.script.JuelScriptEngineFactory" />       <script-language name="bsh" factory="org.jbpm.pvm.internal.script.BshScriptEngineFactory" />       <script-language name="groovy" factory="org.jbpm.pvm.internal.script.GroovyScriptEngineFactory" />     </script-manager>       </process-engine-context> </jbpm-configuration> -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/534370#534370] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
