Jetty: HTTP ERROR: 503/ Service Unavailable

I'm new to Jetty, I tried to run the sample program here "http://www.codeproject.com/Articles/128145/Run-Jetty-Web-Server-Within-Your-Application" but I got error message on my page "http://localhost:8585/runJetty/"

"HTTP ERROR: 503
Problem accessing /runJetty/. Reason: 
    Service Unavailable
--------------------------------------------------------------------------------
Powered by Jetty:// "

Error log I get from eclipse:

"Project... Clean" in Eclipse solved this for me.

Earlier, I had to configure the web.xml correctly.

Remove/Delete the project from workspace. and Reimport the project to the workspace. This method worked for me.

None of these answers worked for me.

I had to remove all deployed java web app:

  • Windows/Show View/Other...
  • Go the the Server folder and select "Servers"
  • Right-click on the J2EE Preview at localhost
  • Click to Add and Remove... Click Remove all

Then run the project on the server

The Error is gone!

You will have to stop the server before deploying another project because it will not be found by the server. Otherwise you will get a 404 error

I had the same problem. I solved it by removing the line break from the xml file. I did 

<operationBindings>
    <OperationBinding>
        <operationType>update</operationType>
        <operationId>makePdf</operationId>
        <serverObject>
            <className>com.myclass</className>
            <lookupStyle>new</lookupStyle>
        </serverObject>
        <serverMethod>makePdf</serverMethod>
    </OperationBinding>
</operationBindings>

instead of ...

<serverObject>
            <className>com.myclass
</className>
            <lookupStyle>new</lookupStyle>
</serverObject>

Actually, I solved the problem. I run it by eclipse jetty plugin.

  1. I didn't have the JDK lib in my eclipse, that's why the message keep showing that I need the full JDK installed, that's the main reason.

  2. I installed two versions of jetty plugin, wich is jetty7 and jetty8. I think they conflict with each other or something, so I removed the jetty7, and it works!

You Log says, that you web.xml is malformed. Line 1, colum 7. It may be a UTF-8 Byte-Order-Marker

Try to verify, that your xml is wellformed and does not have a BOM. Java doesn't use BOMs.
