I am unable to connect to cvs through Eclipse due to firewall problems. I am trying out "cvsgrab" as avik suggested As soon as I set up the cvs I will sent the patch.
If i dont need to send codes like this please tell me.

The byte 0xff is equal to -1 so when you cast it to an int you end up with an int that is equal to -1 (0xffffffff). We want an int that is equal to 255. When you cast from a smaller precision number to a larger precision number (byte->int) the JVM will always preserve the sign. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
