Arquillian & JBoss 7 results in NullPointerException

drosowski Nov 7, 2011 5:30 AM

Hi,

I'm trying to set up Arquillian for our project. We're using Jboss 7.1.0.Alpha2 and Arquillian 1.0.0.CR5. Everything, including the deployment of my package works fine, but when Arquillian tries to connect to JBoss (apparently using JMX), it results in a NPE. First of all, here's the relevant part of my pom.xml:

		<dependency>
			<groupId>org.jboss.arquillian.junit</groupId>
			<artifactId>arquillian-junit-container</artifactId>
			<version>1.0.0.CR5</version>
			<scope>test</scope>
		</dependency>
		<dependency>
			<groupId>org.jboss.as</groupId>
			<artifactId>jboss-as-arquillian-container-managed</artifactId>
			<version>7.0.2.Final</version>
			<scope>test</scope>
		</dependency>

This is my arquillian.xml:

<container qualifier="jboss" default="true">
	<protocol type="jmx-as7">
		<property name="executionType">REMOTE</property>
	</protocol>
	<configuration>
		<property name="jbossHome">C:\\dev\\jboss-as-7.1.0.Alpha2-SNAPSHOT</property>
		<property name="serverConfig">target/test-classes/arquillian_standalone.xml</property>
	</configuration>
</container>

And this is the exception which is being thrown:

-------------------------------------------------------------------------------

Test set: com.mycom.MyTest

-------------------------------------------------------------------------------

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 12.29 sec <<< FAILURE!

test(com.mycom.MyTest) Time elapsed: 0.125 sec <<< ERROR!

Any idea what might be wrong with out setup, or is this an issue with the AS7 nightly build (7.1.0.Alpha2)?

Cheers,

Hi,

apparently one has to use another protocol for Jboss 7, so here is the working portion of my arquillian.xml:


<protocol type="Servlet 3.0">
<property name="executionType">MANAGED</property>
</protocol>

Cheers,
Daniel
