RE: Error socket

You haven't shown us your prototype or code for readIb().

Reading from an input stream is usually a repeated method. You pass the length of the buffer to the read() method and repeat. The method returns the number of bytes actually read into the buffer. After each method call you append the buffered characters to another space.

If your code just hangs, it is waiting for something to appear from the other end. If it is ending, the readIb process is throwing some kind of exception. Check your job log for the error. If there's an error, there's probably also a stack trace in whatever file is being used for STDOUT. Most often that a QPRINT spool file associated with the job.

Thank you Dan.
But my problem is that the method "readIb" is not executed and it does not come to the line display.
Eval String3 = readIb(ib)

Looks like you're going to have code page problems with this. Depends
on how you compile it and what code page your source is. If you have
your source in a source physical file, the code page is some flavor of EBCDIC.
The stuff in your input stream is most likely ASCII. DSPLY is going to
expect EBCDIC.

One way around this is to put your source in a IFS file with code page
1252 or something similar and compile from IFS stream file. RPG would
then do the work to translate to EBCDIC for your output to devices it
knows like those used by the DSPLY op code.

Good morning.
I am creating a client socket and do not manage to read the
inputStreamReader.

Even the line "Eval String3 = readIb(ib)" works perfectly.

Some solution?? Thank you.
