Custom Java Functions

TIBCO API Exchange Gateway bundles the Saxon Professional Edition (PE) product libraries with the installation package to support the Java functions in the XSLT files.

To create your own Java functions and use the functions in the XSLT files, do the following steps:

1.	Create the function in the Java program. The function must have static modifier.

2.	Create the jar file for the java class. Put the jar file in the ASG_HOME/lib/ext/tpcl directory.

3.	Call the function using the package name as namespace in the XSLT file. See the following example:

Java function

The HelloWorld java function is defined as follows:

---

 

package Test;

 

public class HelloWorld {

public static String getName(){

return "Hello";

}

}

---

 

XSLT File

Use the HelloWorld function in an XSLT file as follows:

---

 

<routingKey>

<xsl:value-of select="nameUtils:getName()" xmlns:nameUtils="java:Test.HelloWorld"/>

</routingKey>

---
