BeanShell callout for OSB

Problem with Java Callouts is that they are a pain to maintain - separate Java project, need to build and deploy to OSB project.

If you have frequent, simple Java code to execute, you might avail yourself of an INTERPRETER like BeanShell

Just copy bsh-2.0b4.jar to $DOMAIN_HOME/lib directory, restart your server, and you are ready to use the BeanShellJavaCallout Java wrapper to BeanShell:

package com.acme.javacallout; 

import bsh.EvalError;
import bsh.Interpreter;

public class BeanShellJavaCallout {
 
 public static String callBeanShell(String code) throws EvalError {
  Interpreter i = new Interpreter();
  Object result = i.eval(code);
  return result.toString(); 
 }
 
 
}

package com.acme.javacallout; 

import static org.junit.Assert.*;

import org.junit.Test;

import bsh.EvalError;
import bsh.Interpreter;

public class BeanShellJavaCalloutTest {
 
 @Test
 public void callBeanShellTest() throws EvalError {
  System.setProperty("weblogic.Name", "osbdv1ms1");
  String result = BeanShellJavaCallout.callBeanShell("return java.lang.System.getProperty(\"weblogic.Name\")");
  assertEquals("osbdv1ms1", result);
 }
 
 
}
