XML-RPC Patch

[Robert G Leslie]

Hi, new to the mailing list.  I've been working on adapting JSPWiki for my 
organization, and I wanted to put out some of the code that I've been 
working on to see if it might be worthy of a patch.  I have added several 
methods to the XML-RPC interface in RPCHandler.java.

Here they are:

/**
  * Sets the wiki markup of the specified wiki page to the specified text.
  *
  * @param pageName name of the wiki page whose text will be set
  * @param text     text the wiki page will be set to
  *
  * @return an empty string
  *

  */
  public String setPage( String pageName, String text )
      throws XmlRpcException
  { 
      try
      {
          WikiPage page = new WikiPage( m_engine, pageName );

          WikiContext context = new WikiContext( m_engine, page );

          m_engine.saveText( context, text );
      } 
      catch( Exception e )
      {
          log.error( "Failed to set page", e );
          throw new XmlRpcException( 0, "Failed to set page: " + 
e.getMessage() );
      }
 
      return "";
  }
 
/**
  * Attaches the specified file to the specified wiki page under the 
specified file
  * name.  File must be in Base 64.
  *
  * @param pageName name of the wiki page to which the file will be 
attached
  * @param file     file in Base 64 which will be attached
  * @param fileName name under which the file will be attached
  *
  * @return an empty string

  public String addAttachment( String pageName, String encodedString, 
String fileName )
      throws XmlRpcException, FileNotFoundException, IOException
  { 
      encodedString = encodedString.replaceAll( "\n", "" );
      encodedString = encodedString.replaceAll( "\r", "" );
 
      byte[] encodedBytes = encodedString.getBytes();
 
        org.apache.commons.codec.binary.Base64 decoder = new Base64();
 
        byte[] decodedBytes = decoder.decode( encodedBytes );
 
        try
        {
            m_engine.getAttachmentManager().storeAttachment( new 
Attachment( m_engine, pageName, fileName ), new ByteArrayInputStream( 
decodedBytes ) ); 
        }
        catch( Exception e )
        {
            log.error( "Failed to add attachment", e );
            throw new XmlRpcException( 0, "Failed to add attachment: " + 
e.getMessage() );
        }
 
        return "";
  }
