Hi,

I've tried to make work Tomcat 7 + JSF (myFaces 2) and EclipseLink with Eclipse Helios (tomcat configured and run from Eclipse also) and JDK 1.6, but I have the following problem :
- the first time i try to create an EntityManagerFactory :

emf = Persistence.createEntityManagerFactory("Bank", properties);

I get an exception.
I do this call in a session managed bean call from a web page. If I refresh the page, the call succeeds !

The exception is :


javax.faces.FacesException: Exception [EclipseLink-30005] (Eclipse Persistence Services - 2.3.0.v20110604-r9504): org.eclipse.persistence.exceptions.PersistenceUnitLoadingException

It seems that it searched for the META-INF/persistence.xml in the WEB-INF/classes directory, which does not exists on my installation.
If I create the 'classes' directory, i get another exception :

Internal Exception: java.io.FileNotFoundException: C:\WORK\DEV\Bank\EclipseWKS\Bank\WebContent\WEB-INF\classes


If I copy the META-INF/persistence.xml to this directory, the error disappears.

After looking at source code of JPA, it seems that two directories are searched for the persistence.xml file, but on first "not found" an exception is raised, and the second path is not searched.


Help would be appreciated.
Thanks in advance.

I succeeded to get a workaround of this issue by making a little modification of the source code de EclipseLink :

in the PersistenceUnitProcessor class, I have added a try/catch FileNotFoundException, like this :

public static Set<Archive> findPersistenceArchives(ClassLoader loader, String descriptorPath){
        Archive archive = null;

        Set<Archive> archives = new HashSet<Archive>();

        // See if we are talking about an embedded descriptor
        int splitPosition = descriptorPath.indexOf("!/");

        try {
            // If not embedded descriptor then just use the regular descriptor path
            if (splitPosition == -1) {
                Enumeration<URL> resources = loader.getResources(descriptorPath);
                while (resources.hasMoreElements()){

                    URL descUrl = resources.nextElement();
                    URL puRootUrl = computePURootURL(descUrl, descriptorPath);
                    
                    // *** Here is the "patch"
                    try {
                    	archive = PersistenceUnitProcessor.getArchiveFactory(loader).createArchive(puRootUrl, descriptorPath, null);
                    catch (FileNotFoundException ex)
	            {                        // Ignore this path
	              	archive = null;
	            }
	            // End of patch


I don't know if it's the good way to do, but it works.

Bug #353121 has been submitted.

By the way, I found a workaround that does not require patching of code : I disabled the "Serve modules without publishing" of the Tomcat configuration in Eclipse.
