Subject Re: Multiple persistence.xml in different jars
Date Tue, 14 Oct 2014 04:37:03 GMT
Romain,
It was my fault. I was loading the persistence context using openjpa.
However, switched to OpenEJB to allow scanning for the persistence.xml
in other jars. The problem is the current jar has some EJBs. I am
loading them from maven mojo. In a way, it's similar to unit testing.

  protected void setupClassPath() throws MalformedURLException,
DependencyResolutionRequiredException
    {

    synchronized (this)
    {
        if (classLoader != null)
        return;
    }
    synchronized (this)
    {
        List<URL> urls = new ArrayList<URL>();

        List<String> paths = new LinkedList<String>();

        List<String> compilePath = mavenProject.getCompileClasspathElements();

        List<String> testPath = mavenProject.getTestClasspathElements();

        List<String> runtimePath = mavenProject.getRuntimeClasspathElements();

        List<String> systemPath = mavenProject.getSystemClasspathElements();

        List<Dependency> dependencies = mavenProject.getCompileDependencies();

        this.merge(paths, compilePath);
        this.merge(paths, testPath);
        this.merge(paths, runtimePath);
        this.merge(paths, systemPath);

        getLog().info("Scanning ... ");

        for (Object object : paths)
        {
        String path = (String) object;

        getLog().info("Adding " + path + " to classpath");

        urls.add(new File(path).toURL());
        }

        ClassLoader parent = Thread.currentThread().getContextClassLoader();

        parent = this.getClass().getClassLoader();

        ClassLoader contextClassLoader =
URLClassLoader.newInstance(urls.toArray(new URL[0]), parent);

        Thread.currentThread().setContextClassLoader(contextClassLoader);

        return;
    }
    }

.....

properties.put(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.openejb.client.LocalInitialContextFactory");

    // properties.put(OpenEjbContainer.OPENEJB_EMBEDDED_REMOTABLE, "true");
    properties.put("openejb.validation.output.level", "VERBOSE");

    properties.put("jdbc/dataSource", "new://Resource?type=DataSource");
    properties.put("jdbc/dataSource.JdbcDriver", this.driver);
    properties.put("jdbc/dataSource.JdbcUrl", this.url);
    properties.put("jdbc/dataSource.UserName", this.username);
    properties.put("jdbc/dataSource.Password", this.password);

    properties.setProperty("javax.persistence.transactionType",
"RESOURCE_LOCAL");

    Context ctx;
    try
    {

        ctx = new InitialContext(properties);


The problem I am facing now, is that not all the dependencies are
available for OpenEJB:

I am not sure if adding dependencies to OpenEJB class works using

Thread.currentThread().setContextClassLoader(contextClassLoader);

Thank you.
