Re: [geclipse-dev] JSDL job description creation

["Neophytos Theodorou" <phytosth@xxxxxxxxxxxx>]

Deer Romain. First of all check if the file is actually created in the local disk and in which folder. Another think is instead of trying to create a new JSDL file from the file instance 
try getting it like this
IFolder tempFolder = createTemporaryJSDLFolder();
    IFile tempJSDLFile = createTemporaryJSDLFile(tempFolder);
    IGridElement element = GridModel.getRoot().findElement( tempJSDLFile );
    JSDLJobDescription basicJSDL = null;
    if( element instanceof JSDLJobDescription ) {
      basicJSDL = initializeJSDLJobDescription(( JSDLJobDescription )element);
      basicJSDL.save( tempJSDLFile );
    }

Also I suggest that you take a look at the code of GBDL Benchmark Description. At least I have tested it and it works so you would have a known path to achiece your goal. I'm not also sure on the call on creating a new project. Isn't there a way to use the current project?

Thank you for you answer but using your code I obtains the same exception.

I think the problem is that the file is not being looked for at the right place:
java.io.FileNotFoundException: /myproject/jsdl/myjsld.jsdl  (No such file or directory)

When I create the IFile the getFullPath method gives me:
/myproject/jsdl/myjsld.jsdl

The getJSDLString method of the JSDLJobDescription class contains the following code:

  File jsdlFile = this.getPath().toFile();
  FileInputStream jsdlStream = null;
  jsdlStream = new FileInputStream( jsdlFile );

this.getPath call getFullPath on the IFile. The creation of the input stream is done on the absolute path: /myproject/jsdl/myjsld.jsdl, that does'nt exist.

Is my IFile is not created correctly or is it a bug?

Cheers, Romain.

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)

   </jsdl:JobDefinition>


   Did I miss something?
