Re: [geclipse-dev] JSDL job description creation

["Neophytos Theodorou" <phytosth@xxxxxxxxxxxx>]

Had a simillar problem. it seems that you have to open an output stream to the file to actually create it. This what I have done

private IFile createTemporaryJSDLFile(final IFolder jsdlFolder){
    IFile newJSDL = jsdlFolder.getFile( "." + this.benchmark.getName()

.toLowerCase() + (fileCount++) + ".jsdl" ); //$NON-NLS-1$//$NON-NLS-2$
    if(!newJSDL.exists()){

      try {
        FileOutputStream tempOutStream= new FileOutputStream(newJSDL.getRawLocation().toOSString());
        tempOutStream.close();

        FileInputStream tempInStream = new FileInputStream(newJSDL.getRawLocation().toOSString());
        newJSDL.create( tempInStream, true, null );
        tempInStream.close();


      } catch( FileNotFoundException e ) {
        // TODO Auto-generated catch block
        e.printStackTrace();
      } catch( CoreException e1 ) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
      } catch( IOException e ) {
        // TODO Auto-generated catch block
        e.printStackTrace();
      }
    }
    return newJSDL;
  }

Although It may seem reduntant it actually worked. You can find the rest of the code in eu.geclipse.benchmarking.model.GBDLBenchmarkDescription

Hi All,

I am trying to create a simple jsdl job description with the following code:

         IWorkspace ws = ResourcesPlugin.getWorkspace();
         System.out.println(ws.getRoot().getLocationURI().toString());
         IWorkspaceRoot swRoot = ws.getRoot();
         IProject project = swRoot.getProject( "myproject" );

         if ( ! project.exists() ) {
             project.create( null );
         }

         project.open( null );

         IFile file = project.getFile( "myjsld.jsdl" );

         if(!file.exists()) {                  file.create(new InputStream(){

                 @Override
                 public int read() throws IOException {
                     return -1;
                 }
                                }, IResource.REPLACE, null );
         }

         JSDLJobDescription jsdl = new JSDLJobDescription( file );
         jsdl.create(new JSDLJobDescriptionCreator());
         jsdl.createRoot();
         jsdl.addJobDescription();
         jsdl.addApplication();
         jsdl.setApplicationName("/bin/date");
         jsdl.save(file);

         System.out.println(jsdl.getJSDLString());

But I get the following exception:

java.io.FileNotFoundException: /myproject/myjsld.jsdl (No such file or directory)
 at java.io.FileInputStream.open(Native Method)

At the end of the process the jsdl file has been written:

<?xml version="1.0" encoding="UTF-8"?>
<jsdl:JobDefinition xmlns:jsdl="http://schemas.ggf.org/jsdl/2005/11/jsdl">
<jsdl:JobDescription>
 <jsdl:Application>
   <jsdl:ApplicationName>/bin/date</jsdl:ApplicationName>
 </jsdl:Application>
</jsdl:JobDescription>
</jsdl:JobDefinition>


Did I miss something?
