JBOSS_HOME is not properly being set in Linux, System.getenv from Eclipse returns null

Question

I've added JBOSS_HOME both in Linux and Windows.

Here is my arquillian.xml

http://jboss.org/schema/arquillian/arquillian_1_0.xsd">

    <container qualifier="NON_REST_CONTAINER">
        <protocol type="Servlet 3.0">
        </protocol>
        <configuration>
            <property name="allowConnectingToRunningServer">true</property>
        </configuration>

    </container>

     <container qualifier="REST_CONTAINER"  default="true">
        <protocol type="Servlet 3.0">
        </protocol>
        <configuration>
            <property name="allowConnectingToRunningServer">true</property>
        </configuration>
    </container> 
</group>

In windows tests are running fine but in Linux I'm getting following exception: NullPointerException due to jbossHome variable being null in ManagedDeployableContainer

        final String jbossHome = config.getJbossHome();
        File jbossHomeDir = new File(jbossHome).getCanonicalFile();

Here is the exception trace:

So, what I'm interpreting is JBOSS_HOME is not being read properly by Arquillian not sure why.

When I added jbossHome property in arquillian.xml it's working fine in Linux also. But I don't want to do that since path will be different for Linux and Windows and I want it to be compatible.

Any suggestions/pointers would be much appreciated.

Update:

I tried System.getenv("JBOSS_HOME") from a standalone program and ran it from terminal and it prints JBOSS_HOME, but from my eclipse/testcase it returns null.

Answer 1

From Eclipse you can set the JBOSS_HOME environment variable from the JUnit test launcher, in the Environment tab. This is a workaround in case the environment variable was not defined at the system level (not the shell level).

In Eclipse,

• Open the launcher configurations dialog using the "Run configuration..." menu in the main toolbar (using the arrow on the right side of the Run icon).
• Then select the JUnit test that you want to run, select the Environment tab and click on New to add the JBOSS_HOME env variable to the test you'll run.

Answer 2

Define key value pairs in /etc/environment file. Now logout and login to make the changes applied. It will make these variables available for all processes.

JBOSS_HOME=<JOBSS-PATH>

So, you don't have to run the eclipse from the Terminal shell to make environment variables visible.

It worked for me.
