My client is doing
String s = myEntityBean.getLongStringField();
When the string size is 65530 bytes, it's OK, but when it's 65536, the
client throws a java.io.UTFDataFormatException in
java.io.DataInputStream.readUTF . The EJBServer on the other hand
doesn't have a problem, which is strange because I assume it has to do a
writeUTF at the other end.
Is there a 64K limit for passing strings over this transport
layer/encoding protocol?
If so, is that an RMI thing or a JOnAS thing?
And would I solve this by using binary data, i.e. if I changed my
database field from TEXT to BLOB or BINARY or whatever (and my bean's
member variable to ByteArray or something)?
Would there then be UNICODE issues/problems to avoid?
My stack dump follows. Thanks
Jonathan
