having trouble deploying "hello world" *.rar to jboss 4.2.3

[radai rosenblatt]

Hi.

Im trying to learn JCA. for that purpose i've created a simple "hello world"-style project so i could try and write a simple connector.
Im having trouble getting the attached project to deploy (using JBoss 4.2.3.GA). the failure looks like this :

11:28:28,435 WARN  [org.jboss.system.ServiceController] Problem starting service jboss.jca:service=RARDeployment,name='rar-1.0.rar'
java.lang.ClassNotFoundException: No ClassLoaders found for: com.radai.adapter.DemoResourceAdapter
        at org.jboss.mx.loading.LoadMgr3.beginLoadTask(LoadMgr3.java:306)
        at org.jboss.mx.loading.RepositoryClassLoader.loadClassImpl(RepositoryClassLoader.java:521)

this happens both when i try to deploy just the *.rar file and the *.ear which contains the *.rar
what am i missing ? the class its looking for is there in the archive.

(I'd attach the project but the forum does not allow zip archives)

Thanks in advance for any assistance.

Where exactly is the jar containing this class located?

on my first build attempt it wasnt in the rar at all. to try and correct that i specified the <rarSourceDirectory> of the maven rar plugin config to be /src/main/java, which resulted in the compiled classes being copied into the rar archive, but in an "exploded" form.

only after some digging i discovered that the rar spec requires the classes to be jarred inside the rar, so i had to tweak my maven <build> to look like this:

<build>
        <plugins>
            <!-- the jar needs to be in place before the rar plugin runs, -->
            <!-- so the rar plugin could package it into the archive.     -->
            <plugin>
                <artifactId>maven-jar-plugin</artifactId>
                <executions>
                    <execution>
                        <goals>
                            <goal>jar</goal>
                        </goals>
                        <phase>prepare-package</phase>
                    </execution>
                </executions>
            </plugin>

        </plugins>
    </build>

this produces a working rar archive, but im thinking this should have worked out of the box .... is there any point in trying to ask the maven rar plugin devs about this ? or am i missing something ?

I think you meany *.war / *.jar / *.ear

no, i meant *.rar
it failed when i tried bundling the *.rar inside the *.ear too, but also when i deployed it stand-alone.
it you take a look, you can see the default jboss instance comes with a few bundled *.rars straight out of the box

I would have thought that by default the jar gets included. Atleast that's what the Maven rar plugin doc says about includeJar attribute

Can you post your pom.xml which contains the rar plugin configuration?

By the way, i'll now move this to our Maven forum since this now is more of a Maven question. Ranchers there might have a better idea about this.

its in cluded by default, but its not built by default - which is the odd thing. its like the rar:rar execution completely replaces the jar:jar execution in the lifecycle instead of coming after it. if you "manually" add the jar:jar back into the lifecycle (as i did in the pom.xml) than the jar produced is included in the rar and everything is nice and dandy.
this, to me, seems to be an issue with the rar plugin since in my experience most maven plugins (especially the core ones) just work if you stick to conventions, which i think i have.

the thing that bothers me is that the rar plugin does not work out of the box (i had to add an execution of the jar plugin before it).

Looks like a JBoss AS-specific discussion to me, moving.
