Re: [geclipse-dev] JSDL job description creation

[reuillon <reuillon@xxxxxxxx>]

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.
