wmq-fte precall java failed - websphere-mq-fte

Question

I am implementing a FTE network using Websphere MQ 7.5.
I have developped a java program to be ran as a precall transfert.
here is my procedure :
I have updated the agent.properties file with path to java.exe
restart my agent
create a new transfert
In the call panel, I configure a precall :
program : java
argument : -jar c:\PATH\TO\MY\JAR\myJar.jar myArgument
the transfert fails and the error shown is like java does not receive any argument.
When I test my command in a windows prompt it works.
In addition, my first attempt was to run a batch script containing the java command but it did not work either.
I do not want to use an exit as the program is specific to a transfer.
Edit : I have test a simple java -version command and it works.
<preSourceCall>
<command name="java" retryCount="0" retryWait="0" successRC="0" type="executable">
<argument>-jar C:\mqfteTest\ExitsJava.jar C:\mqfteTest\userExitTest\FileRef_20121023.txt</argument>
</command>
</preSourceCall>
Error returned :
<callResult outcome="failure" retries="0">
<result outcome="failure" returnCode="1" time="2012-10-24T12:39:52.419Z">

Answer 1

I am not quite sure if I have understood the question. Assuming your aim is to invoke Java class before the transfer begins, you can use MFT exits to achieve that. Here is a link to WMQ MFT v7.5 sample source end user exit.

Answer 2

I finally managed to execute my precall:
for the windows platform, I used a batch script and i put the script and the jar in a folder without space in the path.
I did not manage to use the java command and will open a PMR to understand why.
edit :
Finally I have understood why!!
In fact the so called "argumentS" (in the precall conf) are in fact just one argument.
I have also manage to deploy my precall on iseries as400.
the command line is the same but the declaration of shell MUST be
#!/QOpenSys/usr/bin/sh
with #!/bin/sh wmq-fte does not manage to catch the exit of the program
Everything works great now.
I also found a strange behaviour (which will aim to another PMR) :
when the files to send are in a subdirectory of the command path, the transfert fail.
Hope this will help some one.
