Hi guys,
I've got a problem running a batch job on my server, whereas it runs fine from Eclipse on my development workstation.
I've got my Spring environment set up using Roo, made an entity, and make a batch that does some work, and test it well on my develompent box. I initialize my context and do the work, but when I run my batch on the server, the context isn't initialized properly. Here's the code:
public class TestBatch {
private static ApplicationContext context;
@SuppressWarnings("unchecked")
public static void main(final String[] args) {
context = new ClassPathXmlApplicationContext("/META-INF/spring/applicationContext.xml");
try {
@SuppressWarnings("unused")
TestBatch app = new TestBatch();
} catch (Exception ex) {
ex.printStackTrace();
}
}
public void TestBatch() { /** Do Something using the context **/ }
}
And here's the log and exception:
2010-02-16 11:54:16,072 [main] INFO org.springframework.context.support.ClassPathXmlApplicationContext - Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@6037fb1e: startup date [Tue Feb 16 11:54:16 CET 2010]; root of context hierarchy

Any idea or hints as to what's going on? My classpath is set to $PROJECTHOME/target/classes, and all my dependencies are in $PROJECTHOME/target/lib, and I execute using "export CLASSPATH=$PROJECTHOME/target/classes; java -Djava.endorsed.dirs=$PROJECTHOME/target/lib tld.mydomain.myproject.batch.TestBatch"
Is there anything in my setup that looks very wrong? When I run this from Eclipse, no problems, but when I deploy it on the server where I want to run it and run it as described above, I get this problem. Because it runs from Eclipse, I believe my config files are all right, but how can I debug what's causing this? Perhaps I have some config errors or a mismatch between the server and the development workstation after all? Or is this a really weird way of saying file not found, and if so, how do I make sure it finds the correct file??
I'm really looking forward to hearing your suggestions as to how to tackle this problem.
Cheers
Nik
