Subject RE: Async error occurred: java.lang.IllegalStateException when trying to create a basic unit test
Date Tue, 02 Sep 2008 17:55:40 GMT
Hi Ryan

Are you still having problem with this? Have you checked the source code in 
ActiveMQDestination.java:313 that could give a hint what code the NPE is caused by.


Med venlig hilsen

Subject: Async error occurred: java.lang.IllegalStateException when trying to create a basic
unit test


I'm trying to get my feet wet with Camel - so one of the first things I've
done is create a unit test. 

When the test runs, here's the exception I'm getting:

23:08:07,175 ERROR Service:277 - Async error occurred:

I've posted the whole debug log of the test leading up to that exception
here: 

http://pastebin.us/?show=f6e887a7f

What I'm doing in my test is pulling out a bean that is configured to take a
simple bean, grab a Spring jmsTemplate that is injected into it - and call a
convertAndSend with that bean to a destination. 

So I set up (what I thought) was a simple spring-based configuration for my
camel context:

http://pastebin.us/?show=f5b23a95e 

Then I created (what I hoped) would be a simple unit test: 

http://pastebin.us/?show=f225daceb

I'm new to Camel - so if anyone has any ideas what I'm doing wrong, I'd
appreciate it. 

Here's the versions I'm running against (I switched to 1.5-SNAPSHOT after I
couldn't get 1.4.0 to work... I'll probably switch back to 1.4.0)
