Java APIs

I have seen this question has been brought up many times, but all the fixes I have seen either don't apply to my app or don't work. My app simply returns a byte array of a file. It needs to run in 1.4.2. My problems is that as soon as I try to call a remote function via RMI, my client crashes with a java.io.EOFException. Here is the exception:

java.rmi.UnmarshalException: Error unmarshaling return header; nested exception is:
+ java.io.EOFException+
+ at sun.rmi.transport.StreamRemoteCall.executeCall(StreamRemoteCall.java:209)+
+ at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:359)+

+ at java.io.DataInputStream.readByte(DataInputStream.java:250)+
+ at sun.rmi.transport.StreamRemoteCall.executeCall(StreamRemoteCall.java:195)+
+ ... 5 more+

Here is my server code:

    public byte[] getUpdateFile(String os) {
        try{
            String fileName=null;
            if (os.toLowerCase().startsWith("w"))
                fileName=System.getProperty("oware.user.root"+File.separator+"adtranapps"+File.separator+"updater"+File.separator+"updateWin.zip");
            else
                fileName=System.getProperty("oware.user.root"+File.separator+"adtranapps"+File.separator+"updater"+File.separator+"updateSol.zip");
            if (DEBUG) System.out.println("Update File: "+fileName);
            File updateFile=new File(fileName);
            if (updateFile.exists())
            {
                byte[] fileData=new byte[(int)updateFile.length()];
                BufferedInputStream readFile = new BufferedInputStream(new FileInputStream(updateFile));
                if (DEBUG) System.out.println("Reading file...");
                readFile.read(fileData, 0, fileData.length);
                readFile.close();
                return (fileData);
            }
            else {
                System.out.println("ERROR: Update file missing!");
            }
        }
        catch (Exception e) {
            System.out.println("EXCEPTION: Update failed!");
        }
        return null;
    }
