[jboss-user] [Microcontainer] - Retrieve all metadata from a deployment unit.

[beve]

Hi, 

I'm wondering what the correct way of retrieving all metadata from a VFSDeploymentUnit is.
The following test decribes what we are doing. 


  | package org.jboss.deployers.vfs.plugins.structure;
  | 
  | import static org.junit.Assert.assertEquals;
  | import static org.junit.Assert.assertNotNull;
  | 
  | import java.io.IOException;
  | import java.net.URL;
  | import java.util.Arrays;
  | import java.util.List;
  | 
  | import org.jboss.virtual.MemoryFileFactory;
  | import org.jboss.virtual.VFS;
  | import org.jboss.virtual.VirtualFile;
  | import org.junit.Before;
  | import org.junit.BeforeClass;
  | import org.junit.Test;
  | 
  | public class AbstractVFSDeploymentContextTest
  | {
  |     private AbstractVFSDeploymentContext context;
  |     private String fileName = "/WEB-INF/wsdl/test.wsdl";
  |     
  |     @BeforeClass
  |     public static void initVFS()
  |     {
  |         VFS.init();
  |     }
  |     
  |     @Before
  |     public void populateVirtualFileSystem() throws IOException
  |     {
  |         context = new AbstractVFSDeploymentContext();
  |         URL dynamicClassRoot = new URL("vfsmemory", getClass().getSimpleName(), "");
  |         VirtualFile dynamicClasspathDir = MemoryFileFactory.createRoot(dynamicClassRoot).getRoot();
  |         URL wsdlUrl = new URL(dynamicClassRoot + fileName);
  |         MemoryFileFactory.putFile(wsdlUrl, "wsdlcontent".getBytes());
  |         
  |         context.setMetaDataLocations(Arrays.asList(new VirtualFile[] {dynamicClasspathDir}));
  |     }
  |     
  |     @Test
  |     public void getMetaDataFile() throws IOException
  |     {
  |         VirtualFile metaDataFile = context.getMetaDataFile(fileName);
  |         assertNotNull(metaDataFile);
  |     }
  |     
  |     @Test
  |     public void getMetaDataFiles() throws IOException
  |     {
  |         List<VirtualFile> metaDataFiles = context.getMetaDataFiles(null, "");
  |         assertEquals(1, metaDataFiles.size());
  |     }
  |     
  |     @Test
  |     public void getAllMetaDataFiles() throws IOException
  |     {
  |         List<VirtualFile> metaDataFiles = context.getAllMetaDataFiles();
  |         assertEquals(1, metaDataFiles.size());
  |     }
  |       
  | }
  | 
Now, the second test method, getMetaDataFiles, fails. This is what we are currently using to retrieve all metadata. Is there another way of retrieving all metadata?

For the third test method I add the following method to AbstractVFSDeploymentContext and it returns all metadata from the deployment context:
public List<VirtualFile> getAllMetaDataFiles()
  |   {
  |     List<VirtualFile> results = new ArrayList<VirtualFile>();
  |     try
  |     {
  |         for (VirtualFile location : metaDataLocations)
  |         {
  |            List<VirtualFile> result = location.getChildren();
  |            if (result != null && result.isEmpty() == false)
  |            {
  |               results.addAll(result);
  |               deployed();
  |            }
  |         }
  |     }
  |     catch(final IOException e)
  |     {
  |         log.debug("Error retrieving all meta data");
  |     }
  |     return results;
  |   
}

This is related to this jira: https://jira.jboss.org/jira/browse/JBWS-2619

Thanks,
