[esb-issues] [JBoss JIRA] Commented: (JBESB-1683) ScriptingAction donation to support more languages

ScriptingAction donation to support more languages -------------------------------------------------- Key: JBESB-1683 URL: http://jira.jboss.com/jira/browse/JBESB-1683 Project: JBoss ESB Issue Type: Feature Request Security Level: Public(Everyone can see) Components: Build and Release, Examples, Rosetta, Testing Affects Versions: 4.2.1 Environment: agnostic Reporter: David Ward Attachments: jbossesb-scripting.zip Original Estimate: 2 hours Remaining Estimate: 2 hours This is a donation to add a greater scripting capability to JBoss ESB. Currently, only Groovy is supported via the GroovyActionProcessor. This new donation, the ScriptingAction, uses the Apache Jakarta Bean Scripting Framework (BSF) to support any of the 23 scripting languages it supports, Groovy being one of them. Yes, I thought of the Java 6 javax.script package, but everything in JBoss ESB 4.2 needs to work with JDK 5, thus my choice. Everything has been built against http://anonsvn.jboss.org/repos/labs/labs/jbossesb/trunk as of 2008-04-19 03:45:28 -0400 (Sat, 19 Apr 2008).

'twasn't me! ;) You will also notice the addition of BSF 2.4.0, and the upgrade of BeanShell from 1.3.0 to 2.0b4 in AS (something I've wanted for a long time). Last, I fixed the quickstarts.properties-example file to reflect the change to jbossesb-server-4.2.1GA. Now, for the meat. The relatively simple code lives in ScriptingAction.java, which was modeled after GroovyActionProcessor.java. There is also a test case, ScriptingActionUnitTest, which exercises both BeanShell and Groovy scripts: [java] [junit] Running org.jboss.soa.esb.actions.scripting.ScriptingActionUnitTest [java] [junit] Testsuite: org.jboss.soa.esb.actions.scripting.ScriptingActionUnitTest [java] [junit] Tests run: 5, Failures: 0, Errors: 0, Time elapsed: 1.392 sec [java] [junit] Tests run: 5, Failures: 0, Errors: 0, Time elapsed: 1.392 sec [java] [junit] ------------- Standard Output --------------- [java] [junit] EMMA: collecting runtime coverage data ...

It has an action pipeline which calls out to BeanShell, Groovy, Python, and JavaScript. (Note: bsf.jar and bsh.jar are in the server's lib directory because older versions were already there. Python uses the jython library, and JavaScript uses the Mozilla Rhino library - both of which have different licenses. Thus, I did not included them in the server's lib directory. I only put them in just the quickstart's lib directory.) ANYwho, it runs fine in both '.esb' archive mode: 01:13:11,865 INFO [STDOUT] Hello World from BeanShell! 01:13:11,926 INFO [STDOUT] Hello World from Groovy! 01:13:11,960 INFO [STDOUT] Hello World from Python! 01:13:11,968 INFO [STDOUT] Hello World from JavaScript! as well as in standalone mode: [qsjava] Hello World from BeanShell!
