Re: [jetty-users] embedded jetty and onejar plugin
|
Instead of one-jar, try the assembly plugin with it's `jar-with-dependencies` built-in descriptorRef:

Hi,
I am trying to create an application using embedded Jetty (version 7.4.0.v20110414) and want to package it using the onejar maven plugin (http://code.google.com/p/onejar-maven-plugin/).
Here is the code where I start jetty:
Server server = new Server(8180);
ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
context.setContextPath("/");
context.setWelcomeFiles(new String[]{"index.html"});
ServletHolder servletHolder = new ServletHolder(new DefaultServlet());
URL resource = getClass().getResource("/web/");
String resourceBase = resource.toURI().toString();
servletHolder.setInitParameter("resourceBase", resourceBase);
context.addServlet(servletHolder, "/");
server.setHandler(context);
server.start();
When I do java -jar onejar.jar and go to http://localhost:8180/index.html I get a 404.
My onejar.jar looks like this:
onejar.jar
main/myapp.jar
main/myapp.jar/web/index.html
(Rest omitted for readability).
I debugged through the application and noticed it throws (and ignores) an exception in the org.eclipse.jetty.util.resource.JarFileResource class in the method exists() in this piece of code:
try
{
JarURLConnection c=(JarURLConnection)((new URL(_jarUrl)).openConnection());
c.setUseCaches(getUseCaches());
jarFile=c.getJarFile();
}
catch(Exception e)
{
Log.ignore(e);
}
The _jarUrl contains: jar:file:/target/onejar.jar!/main/myapp.jar!/web/index.html and throws a ZipException when doing c.getJarFile(): java.util.zip.ZipException: error in opening zip file.
Does anyone has experience in using embedded jetty with the mentioned onejar plugin? What I'd like to do is do java -jar myjar.jar where myjar contains everything that is needed, no additional files and such.
Extra information:
I also created a unit test for this asfollows:
@Test
public void defaultServlet() throws Exception {
final Server server = new Server(8181);
ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
context.setContextPath("/");
context.setWelcomeFiles(new String[]{"index.html"});
DefaultServlet defaultServlet = new DefaultServlet();
ServletHolder servlet = new ServletHolder(defaultServlet);
servlet.setInitParameter("resourceBase", "jar:file:/target/onejar.jar!/main/myapp.jar!/web/");
context.addServlet(servlet, "/");
server.setHandler(context);
server.start();
Resource resource = defaultServlet.getResource("/index.html");
assertNotNull(resource);
server.stop();
}
This tests succeeds, meaning resource is not null. Does a real request use something else to find the resources that the getResource method on the servlet?
Thanks in advance,
Lars
