Setting Jetty resourcebase to static file embedded in the same jar file

I am trying to access static resource (eg. first.html) packed inside the same .jar file (testJetty.jar), which also has a class which starts the jetty (v.8) server (MainTest.java). I am unable to set the resource base correctly.

The structure of my jar file (testJetty.jar): testJetty.jar

  • first.html

  • MainTest.java

== Works fine on local machine, but when I wrap it in jar file and then run it, it doesn't work, giving "404: File not found" error.

I tried to set the resourcebase with the following values, all of which failed:

a) Tried setting it to .

resource_handler.setResourceBase("."); // Results in directory containing the jar file, D:\Work\eclipseworkspace\testJettyResult

b) Tried getting it from getResource

ClassLoader loader = this.getClass().getClassLoader();
File indexLoc = new File(loader.getResource("first.html").getFile());
String htmlLoc = indexLoc.getAbsolutePath();
resource_handler.setResourceBase(htmloc); // Results in D:\Work\eclipseworkspace\testJettyResult\file:\D:\Work\eclipseworkspace\testJettyResult\testJetty1.jar!\first.html

c) Tried getting the webdir

String webDir = this.getClass().getProtectionDomain()
        .getCodeSource().getLocation().toExternalForm();
resource_handler.setResourceBase(webdir); // Results in D:/Work/eclipseworkspace/testJettyResult/testJetty1.jar

None of these 3 approaches worked.

Any help or alternative would be appreciated

Thanks abbas

Solution

  • Not unusually, I found a solution to my problem. The 3rd approach mentioned by Stephen in Embedded Jetty : how to use a .war that is included in the .jar from which Jetty starts? worked!

    So, I changed from Resource_handler to WebAppContext, where WebAppContext is pointing to the same jar (testJetty.jar) and it worked!

        String webDir = MainTest.class.getProtectionDomain()
            .getCodeSource().getLocation().toExternalForm(); ; // Results in D:/Work/eclipseworkspace/testJettyResult/testJetty.jar
    WebAppContext webappContext = new WebAppContext(webDir, "/");
