[jboss-dev-forums] [Design of JBoss ESB] - Scripting Language ESB Action

Purpose: To discuss the design of possible scripting language support in the JBoss ESB (post 4.0 GA) Groovy scripts can already be used inside of the transformation engine. quickstarts\transform_EDI2XML_Groovy_XSLT illustrates this capability. Here are the primary questions to be answered when designing a scripting language ESB action: A- Which scripting languages should be supported? Limit it to Groovy or more? B- Support for Java 5 and Java 6? Java 6 using JSR 223 introduces the javax.scripting package which allows for plug & play with various scripting engines: https://scripting.dev.java.net/ If Java 5 is a requirement then perhaps we leverage the capabilities of http://jakarta.apache.org/bsf/ C- What should the jbossesb.xml look like (here is an example to start the discussions): | <action class="org.jboss.soa.esb.actions.ScriptingAction" name="ScriptingAction"> | <property name="scriptEngine" value="MyScriptingEngine"/> | <property name="scriptName" value="MyGroovyScript.groovy"/> | </action> | D- How should the scripting language interact with org.jboss.soa.esb.message.Message | E- What documentation/samples need to be included? At a minimum, a quickstart that illustrates the use of scripting. It should also be "hot redeployable" much like the Rules-based ContentBasedRouting (illustrated by quickstarts\fun_cbr) F- Any volunteers who wish to pursue this item? If you download the SRC for JBoss ESB you can review: trunk\product\core\listeners\src\org\jboss\soa\esb\actions for examples on how to build an "internal" action that would be part of the JBoss ESB download.
