SerialInitContextFactory not found in glassfish naming

问题

This one starts to drive me completely nuts ...

I want to create a Glassfish client application using Maven.

For that, I've added the requried gf-client dependency :

    <dependency>
        <groupId>org.glassfish.appclient</groupId>
        <artifactId>gf-client</artifactId>
        <version>3.1</version>
        <type>pom</type>
        <scope>compile</scope>
    </dependency>

Then, wanting to contact my Glassfish server, running on the same application, I do the usual lookup :

Properties p = new Properties();
// optional. Defaults to localhost. Only needed if web server is running
// on a different host than the appserver
p.setProperty("org.omg.CORBA.ORBInitialHost", "localhost");
// optional. Defaults to 3700. Only needed if target orb port is not
// 3700.
p.setProperty("org.omg.CORBA.ORBInitialPort", "3700");
Context context = new InitialContext(p);
// Stores the list of reachable EJBs
return context.lookup(interfacesToNames.getProperty(className));

Unfortunatly, when doing so, all I get is

Caused by: javax.naming.NoInitialContextException: Cannot instantiate class: com.sun.enterprise.naming.impl.SerialInitContextFactory [Root exception is java.lang.ClassNotFoundException: com/sun/enterprise/naming/impl/SerialInitContextFactory]

After some checks, I've noticed that my glassfish-naming-3.1.jar is present in CLASSPATH for that client application. And, according to Eclipse code lookup, it is this jar that should contain com.sun.enterprise.naming.impl.SerialInitContextFactory. However, if in debug mode, I do getClass().getClassLoader().getResource("com/sun/enterprise/naming/impl/SerialInitContextFactory") it returns me null, which clearly indicates that the class can't be found.

For more infos, the JAR is copied from my local maven repository using this plugin configuration :

        <plugin>
            <artifactId>maven-dependency-plugin</artifactId>
            <executions>
                <execution>
                    <id>package output directory</id>
                    <phase>package</phase>
                    <goals>
                        <goal>copy-dependencies</goal>
                    </goals>
                    <configuration>
                        <prependGroupId>true</prependGroupId>
                        <includeScope>compile</includeScope>
                        <outputDirectory>${dependencies.outputDir}/jars</outputDirectory>
                        <prefix>${dependencies.outputDir}</prefix>
                    </configuration>
                </execution>
            </executions>
        </plugin>

Furthermore, I have to confess that, when running a simple test using the same API to connect to Glassfish server, there is absolutely no problem, which directs me to a ClassLoader issue.

When running that client, the current class loader is (as denoted by getClass().getClassLoader().getClass().getName()) sun.misc.Launcher$AppClassLoader. Which unfortunatly is exactly the same than when running unit test.

So, what can I do to solve that bug ?

EDIT Class exists in glassfish-naming-3.1.jar, but does not seems to be findable by standard classloader.

EDIT An interesting discovery :

getClass().getClassLoader().getResource("com/sun/enterprise/naming/impl") = jar:file:/C:/Users/pouet/pouet/target/jars/glassfish-naming-3.1.jar!/com/sun/enterprise/naming/impl

while

getClass().getClassLoader().getResource("com/sun/enterprise/naming/impl/SerialInitContextFactory") = null

回答1:

For a reason I not totally understand, there is a configured Context classloader when run in application. This classloader seems to use some kind of OSGi naming restriction.

As a consequence, to avoid the bug, I reset the context class loader :

Thread.currentThread().setContextClassLoader(getClass().getClassLoader());

And it worked !

Have you tried using the ACC? Your solution seems contrived.
