Object not bound in context

Hi

I took over some source code from another developer.  Most of the items are working fine but I am battling with one part of the code where I am getting an [Object] not bound in this context error.

The source code from the relevant class is as follows:

      public static FileManager getFileManager() throws NamingException {
            log.trace("Trying to set up FM - step 1.");      
            FileManager fm = null;
            log.trace("Trying to set up FM - step 2.");      
            Properties env = new Properties();
            env.setProperty("java.naming.factory.initial","com.sun.jndi.rmi.registry.RegistryContextFactory");
            env.setProperty("java.naming.provider.url","localhost:1099");
            env.setProperty("java.naming.factory.url.pkgs","org.jnp.interfaces");
            InitialContext ctx = new InitialContext(env);
            log.trace("Trying to set up FM - step 3.");      
            fm = (FileManager) ctx.lookup("121/FileManager");
            log.trace("Trying to set up FM - step 4.");      
          return fm;
      }

The source code for the FileManager class is as follows:
package za.co.oneTwoOne.fileManager;

import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import java.sql.SQLException;

import javax.ejb.Local;
import javax.sql.RowSet;

@Local
public interface FileManager {

      /**
       * Returns a new fileID
       * @param userID The userID of the caller
       * @return A fileID that can be written to
       * @throws SQLException
       */
      public abstract int getFileID(int userID) throws SQLException;

      public abstract int getFileID(int userID, String fileName) throws SQLException;
      
      public abstract RowSet getFileProperties(int userID, int fileID)
                  throws SQLException;

      /**
       * Returns a java File object that can be manipulated. This file
       * represents a new file in the store.
       * @param userID The id of the user manipulating this fil
       * @param fileID The fileID of the file
       * @return A file object
       * @throws IOException
       * @throws SQLException
       */
      public abstract File getFile(int fileID) throws IOException, SQLException;

      /**
       * Returns a handle to a file (if the file did not exist, it is created).
       * @param userID The userID of the requesting user
       * @param fileID The fileID
       * @return A file object
       */
      public abstract File getFile(int userID, String fileName) throws IOException, SQLException;

      /**
       * Instead of returning a File object, this function returns an inputstream
       * @param fileID The fileID to read
       * @return
       * @throws SQLException
       * @throws IOException
       */
      public abstract InputStream getInputStream(int fileID)
                  throws SQLException, IOException;

      /**
       * For references to URLs stored in the file management system, return the associated URL
       * @param fileID the FileID
       * @return
       * @throws SQLException
       */
      public abstract String getURL(int fileID) throws SQLException;

      /**
       * Define this files' file name
       * @param userID
       * @param fileID
       * @param fileName
       * @throws SQLException
       */
      public abstract void setFileName(int userID, int fileID, String fileName)
                  throws SQLException;

      /**
       * Retrieve the filename associated with a fileID
       * @param fileID
       * @return
       * @throws SQLException
       */
      public abstract String getFileName(int fileID) throws SQLException;

      /**
       * Retrieves the mimetype of this file
       * @param fileID
       * @return
       * @throws SQLException
       */
      public abstract String getContentType(int fileID) throws SQLException;
      
      public abstract String getPathForFileID(int fileID);
      public abstract String getPathSeperator();
      public abstract int getMaxFilesPerDirectory();

}

There is a configuration file located at C:\ containing some parameters as set out below:
## FileManagerSettings
# Beware that if you enter this as c:\121\Files it will not work (the server will
# drop the \s (c:121Files) which won't work.
# All sizes in bytes
FileManagerRootDirectory=C:/var/121/Files
FilePathSeparator=/
FileUploadMaxSize=67108864
FileUploadMaxSizeHandledInMemory=16384
TemporaryFilePath=C:/var/121/TemporaryFiles/
DefaultFileID=237252

From the rest of the code it seems that this configuration file is being loaded successfully.

I will appreciate your help.
