I had the same problem  I solved it by removing the line break from the xml file  I did    lt operationBindings gt       lt OperationBinding gt           lt operationType gt update lt  operationType gt           lt operationId gt makePdf lt  operationId gt           lt serverObject gt               lt className gt com myclass lt  className gt               lt lookupStyle gt new lt  lookupStyle gt           lt  serverObject gt           lt serverMethod gt makePdf lt  serverMethod gt       lt  OperationBinding gt   lt  operationBindings gt    instead of       lt serverObject gt               lt className gt com myclass  lt  className gt               lt lookupStyle gt new lt  lookupStyle gt   lt  serverObject gt

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

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