Have you tried running your java program via the command line using the
.jar file you created? For example:
java -cp C:/STAF/samples/demo/STAFProcessJDBC.jar;%CLASSPATH% STAFMonitor
That is the command that you're essentially running via your STAX job, If
that doesn't work, then maybe you have a problem with the .jar file you
created (or something).
In the NoClassDefFoundError it says "wrong name:
staf_monitor/STAFMonitor". What is this staf_monitor package/directory
that it is referring to?

Subject: [staf-users] Invoking JAVA Class through STAX...
Hello Sir/Ma'am,
1. My JAVA source code is: STAFMonitor.java, which is getting executed
successfully without any error on JAVA IDE/Eclipse.
· I have created two table in mysql database as "emp" and "emp1"
with 5 columns each.
· I have created a procedure in mysql database which inserts 1000
records in emp, retrieve those 1000 records and insert back those 1000
records in emp1 (all one-by-one).
· I have created a method im my JAVA class, which is getting a
successful connection with the mysql server and calling that stored
procedure.
2. My JAVA executable is : STAFMonitor.class
3. I have created my jar file from STAFMonitor.class as
STAFProcessJDBC.jar
4. I have included this STAFProcessJDBC.jar file as
C:\STAF\samples\demo\STAFProcessJDBC.jar along with STAFMonitor.java as
C:\STAF\samples\demo\STAFMonitor.java
5. I have also included JSTAF.jar and STAFProcessJDBC.jar to the CLASSPATH
6. My stafJDBC.xml is inside C:\STAF\services\stax\samples\stafJDBC.xml
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE stax SYSTEM "stax.dtd">
<stax>
<defaultcall function="main"/>
<function name="main">
<sequence>
<process name="'Run STAF JDBC'">
<location>'local'</location>
<command mode="'shell'">'java STAFMonitor'</command>
<env>'CLASSPATH=C:/STAF/samples/demo/STAFProcessJDBC.jar;{STAF/Env/CLASSPATH}'</env>
<stderr mode="'stdout'"/>
<returnstdout/>
</process>
<if expr="RC != 0">
<log message="1">
'Process Error: RC=%s, STAFResult=%s, STAXResult=%s' % \
(RC, STAFResult, STAXResult)
</log>
<else>
<log message="1">'Process RC was 0. STAXResult=%s' %
STAXResult</log>
</else>
</if>
</sequence>
</function>
7. Now when we are submitting stafJDBC.xml as a new job through the STAX
GUI, it is giving the following message (The job id is successfully
getting generated).
Here is the Message:
Process Error: RC=1, STAFResult=None,
STAXResult=[[0,u'java.lang.NoClassDefFoundError: STAFMonitor (wrong name:
staf_monitor/STAFMonitor)\r\n\tat

in thread "main"']]
I have also tried the command: C:\STAF\samples\demo>jar tf
STAFProcessJDBC.jar
The output is:
META-INF/
META-INF/MANIFEST.MF
STAFMonitor.class
àCan you please suggest me the solution for the same...
Thanks & Regards,
