JEXIT Examples

The JEXIT examples are based on the following defined Java classes.
class :
package com.ibm.websphere.dtx.test;
public class TestJExit {
	Person person = new Person();
	public TestJExit() {		
	}
	public String toUpper(String test) {
		return test.toUpperCase();
	}
	public String Concat(String test1, String test2) {
		return test1 + test2;
	}
	public Integer toNumber(String test1) {
		return new Integer(test1);
	}
	public Double toDouble(String test1) {
		return new Double(test1);
	}
	public void toNothing() {
	}
	public int returnint() {
		return 9;
	}
	public byte returnbyte() {
		return 8;
	}
	public Person getPerson() {
	   return person;
	}	
}

class :
package com.ibm.websphere.dtx.test;
public class Person{
	private String ext = new String("DTX");
	private String name = new String("Websphere");
	public Person() {		
	}
	public String getName() {
		return name;
	}
	public String getExt() {
		return ext;
	}
}

Simple primitive types and simple objects

  • JEXIT ("com.ibm.websphere.dtx.test.TestJExit " , "toUpper" , "HCL")

    Returns HCL

  • JEXIT ("com.ibm.websphere.dtx.test.TestJExit" , "Concat" , "HCL Link", " Link")

    Returns HCL Link

  • JEXIT ("com.ibm.websphere.dtx.test.TestJExit" , "toDouble" , "12")

    Returns 12.0

  • JEXIT ("com.ibm.websphere.dtx.test.TestJExit" , "toNumber" , "12")

    Returns 12

  • JEXIT ("com.ibm.websphere.dtx.test.TestJExit" , "returnint")

    Returns 9

  • JEXIT ("com.ibm.websphere.dtx.test.TestJExit" , "returnbyte")

    Returns 8

Complex objects

When the function is returning a complex object, the returning object is added to the object pool and the key is returned to the map rule.
  • JEXIT ("com.ibm.websphere.dtx.test.TestJExit " , "getPerson")

    Returns a key (as a string)

  • JEXIT ("key" , "getName")

    Returns Websphere

  • JEXIT ("key" , "<destroy>")

    Deletes the Person object from the JVM memory. The "<destroy>" method must be invoked before the map completes processing.
