Won't load WebApplicationInitializer from fat jar

Question

Won't load WebApplicationInitializer from fat jar

Closed this issue 12 years ago · 5 comments

I am stumped and have not been able to figure out how to make this project run directly from the fat jar. Maven builds it just fine but if I try and start using: java -jar jetty-noxml-1.0-SNAPSHOT.jar it will not find the WebAppInitializer.

If I unzip the jar unzip ../jetty-noxml-1.0-SNAPSHOT.jar and do this it works just fine: "java -cp . com.sjl.Main"

Is there some way to make it run from the "fat" jar?

Here is the console output for the failure case:

Fixed - the AnnotationParser was ignoring jar URI's, so it ignored the shaded jar.

Steve,

Thank you for the fix and also thanks for this great piece of code that is perfect for a starting point of a project.

Answer 3 · 2015-09-23T16:21:45.000Z

do you have an example using jetty 9. It is really annoying 9 version...

Answer 4 · 2015-09-29T08:30:11.000Z

@aehtiopicus a friend and ex-colleague of mine mailed me this some time ago, but I never got around to updating the github project:

public void parseContainerPath (final WebAppContext context, final AnnotationParser parser) throws Exception
        {
            //always parse for discoverable annotations as well as class hierarchy and servletcontainerinitializer related annotations
            final Set<AnnotationParser.Handler> handlers = new HashSet<AnnotationParser.Handler>();
            handlers.addAll(_discoverableAnnotationHandlers);
            handlers.addAll(_containerInitializerAnnotationHandlers);
            if (_classInheritanceHandler != null)
                handlers.add(_classInheritanceHandler);

            _containerPathStats = new CounterStatistic();

            List<Resource> _resources = new ArrayList<Resource>();
            _resources.addAll(context.getMetaData().getContainerResources());
            _resources.addAll(getSelfResources(getClass().getClassLoader()));

            for (Resource r : _resources)
            {
                //queue it up for scanning if using multithreaded mode
                if (_parserTasks != null)
                {
                    ParserTask task = new ParserTask(parser, handlers, r, _containerClassNameResolver);
                    _parserTasks.add(task);  
                    _containerPathStats.increment();
                }
            } 
        }

        private List<Resource> getSelfResources(ClassLoader aLoader) throws IOException
        {
            URL _url = aLoader.getResource("com/aub/library/servlets");

            Resource _r = new CustomResource(Resource.newResource(_url));

            return Arrays.asList(_r);
        }

And since they decided not to allow us have sub implementations of jarfileresource, i did the following:

public class CustomResource extends Resource 
{
private Resource delegate;

public CustomResource(Resource aDelegate)
{
    delegate = aDelegate;
}

@Override
public boolean isContainedIn(Resource r) throws MalformedURLException
{
    return delegate.isContainedIn(r);
}

@Override
public void close()
{
    delegate.close();
}

@Override
public boolean exists()
{
    return delegate.exists();
}

@Override
public boolean isDirectory() {
    return delegate.isDirectory();
}

@Override
public long lastModified() {
    return delegate.lastModified();
}

@Override
public long length() {
    return delegate.length();
}

@Override
public URL getURL() {
    return delegate.getURL();
}

@Override
public File getFile() throws IOException {
    if(delegate.getClass().getSimpleName().equalsIgnoreCase("JarFileResource"))
        return new File(getName());

    return delegate.getFile();
}

@Override
public String getName() {
    return delegate.getName();
}

@Override
public InputStream getInputStream() throws IOException
{
    return delegate.getInputStream();
}

@Override
public ReadableByteChannel getReadableByteChannel() throws IOException
{
    return delegate.getReadableByteChannel();
}

@Override
public boolean delete() throws SecurityException {
    return delegate.delete();
}

@Override
public boolean renameTo(Resource dest) throws SecurityException {
    return delegate.renameTo(dest);
}

@Override
public String[] list() {
    return delegate.list();
}

@Override
public Resource addPath(String path) throws IOException,
        MalformedURLException {
    return new CustomResource(delegate.addPath(path));
}

@steveliles Hi Thanks for the reply. I am having a really bad time trying to make it work with version 9. So I will keep on 8 although it is deprecated. The issue is that Spring doesn't boot at all and no messages are thrown to console but I got 503 or in the best case 404. If I get it running I will post it back.
