Websphere MQ File Transfer Java/JAXB file transfer

Prerequisites for the Java JAB Setup:

1. Collect the XSD files that are shipped with WebSphere MQ File Transfer Edition

2. Use the xjc utility to create the Java classes that allow manipulating the XML documents that conform to those XSD files

3. Create a WebSphere MQ text message containing the WebSphere MQ File Transfer Edition request

4. Put that message to the appropriate WebSphere MQ queue.

Step 1:

Create the Java classes that allow WebSphere MQ File Transfer Edition schema file manipulation. Go to the directory E:\student\Java. The sub directory xsd contains the schema files while the sub directory jaxb-ri-20070122 contains the JAXB support. This support has been already installed here, but it can be downloaded from https://jaxb.dev.java.net/2.0.5/

The sub directory temp is empty at the moment.

Open a DOS command prompt

Navigate to E:\student\Java\jaxb-ri-20070122\bin.

Enter this command:

xjc -d E:\student\Java\temp -p generated E:\student\Java\xsd\fteutils.xsd

Step 2: Now we create the main file transfer request classes via the command:

xjc -d E:\student\Java\temp -p generated E:\student\Java\xsd\FileTransfer.xsd

All the generated classes are now in the directory E:\student\Java\temp\generated

Step 3: Open Java perspective in WMQ Explorer

Create a new Java Program

Step 4: Import external Jars into project:

The Java program will use external jar files:

– the JAXB jar file to support JAXB

– the WebSphere MQ jar files to support WebSphere MQ programming

For this reason we have to set references of the Java project to the appropriate jar files

Right click on the Java project à Properties

Add the following packages:





Step 5: Create two new packages

1. generated (it will contain the Java classes generated by JAXB)

2. it.mqfte.xml (it will contain the developed program
