OpenSound java and Max/Msp

Hello Everybody, I'am new to audio processing and it is very wonderful what is possible to do with osc and Max.

I have to write an application in java that send control to a max/msp application, I downlaod the osc and configure everything but I don't understand the message specification, When ever I send a message from java to msp, I receive this error message.

net.recv.udp: OSC Bad message name string: DataAfterAlignedString: Unreasonably long string
Dropping entire message.

Can anyone help me???

The .pat file contains an udpread object and a print object.
Thanks
