[geclipse-dev] Certificate class problem

[reuillon <reuillon@xxxxxxxx>]

Hi again every body,

I am actually building an autonomous application taking benefit of 
geclipse architecture that will submit jobs on computational grids.

For that I think I need to download the  certificates of the 
authorities. I have a problem witting the code that downloads the 
certificates because the
EUGridPMACertificate class is in the package 
eu.geclipse.core.internal.auth, that in internal.

The code I have written is (EFSFile is a class that simplify file usage 
over EFS):

           byte[] certificateData = null;
           byte[] infoData = null;

           String DEFAULT_LOCATION = 
"http://www.eugridpma.org/distribution/igtf/current/accredited/tgz";;
           URI defaultURI;

           defaultURI = new URI( DEFAULT_LOCATION );

           EFSFile repo = new EFSFile(defaultURI);
           List< String > result = new ArrayList< String >();

           InputStreamReader iReader = new 
InputStreamReader(repo.openInputStream());
           BufferedReader bReader = new BufferedReader( iReader );
           StringBuffer buffer = new StringBuffer();
           String line;
           while ( ( line = bReader.readLine() ) != null ) {
               buffer.append( line );
           }

           String content = buffer.toString().replaceAll( " ", "" ); 
//$NON-NLS-1$ //$NON-NLS-2$
           int index = -1;
           while ( ( index = content.indexOf( "ahref=\"", index+1 ) ) > 
0 ) { //$NON-NLS-1$
               int endIndex = content.indexOf( "\">", index+7 ); 
//$NON-NLS-1$
               if ( endIndex > 0 ) {
                   String file = content.substring( index+7, endIndex );
                   if ( file.toLowerCase().endsWith( ".tar.gz" ) 
//$NON-NLS-1$
                           || file.toLowerCase().endsWith( ".tgz" ) ) { 
//$NON-NLS-1$
                       result.add( file );
                   }
               }
               index = endIndex;
           }

           for(String certName: result) {
             URI uri = new URI( defaultURI.toString() + "/" + certName 
); //$NON-NLS-1$
             
             EFSFile cert = new EFSFile(uri);

             InputStream iStream = cert.openInputStream();
             BufferedInputStream bStream = new BufferedInputStream( 
iStream );
             GZIPInputStream zStream = new GZIPInputStream( bStream );
             TarInputStream tiStream = new TarInputStream( zStream );
             TarEntry tEntry;
             while ( ( tEntry = tiStream.getNextEntry() ) != null ) {
               if ( !tEntry.isDirectory() ) {

                 IPath oPath = tEntry.getPath();
                 String extension = oPath.getFileExtension();

                 if ( 
*PEMCertificate*.CERT_FILE_EXTENSION.equalsIgnoreCase( extension ) ) {
                   certificateData = readFromStream( tiStream );
                 } else if (* 
EUGridPMACertificate*.INFO_FILE_EXTENSION.equalsIgnoreCase( extension ) ) {
                   infoData = readFromStream( tiStream );
                 }
               }
             }
           }
           if ( ( certificateData != null ) && ( infoData != null ) ) {
              result = *new EUGridPMACertificate( certificateData, 
infoData );*
           }

Is there a way of bypassing it?

Sorry to bother. Once, I will be finished I will publish the code as a 
tutorial, if you are interested.
