Status: Unverified
FACT(s) (Environment):
Progress 9.1x
SYMPTOM(s):
Java application is sending large XML files to Progress via sockets
Randomly the data within the 4GL program is slightly corrupted
CAUSE:
The code in the applications read-response procedure is having a problem processing the data because the READ method is invoked using the READ-AVAILABLE option instead of READ-EXACT-NUM. Basically, the code is not handling the possibility that more data may arrive between the time when GET-BYTES-AVAILABLE is invoked and when the READ method is invoked.
FIX:
Modify the source code to read exactly the number of bytes returned by the initial call to GET-BYTES-AVAILABLE.
