I'm having a problem related with the "c$socket" routine, i'm trying to comunicate with a Java aplication and the comunication is established, but no data is passed, when I make a write the other aplication receives nothing and when I make a read acucobol keeps waiting for data and doesn't receive nothing. Can someone help me out ? Thx.

    I can't help you but I did play with that a couple months ago and ran into the exact same problem!

    We have multiple examples showing how to use the c$socket routine, some of them in the sample directory. Have you looked there?

    Also, remember to think about c$socket like a file. You must use the sequences: open, read/write and close.

    And don't forget the server, one side must be the server, which then will have to wait listening for incoming "calls", when there is one, it has to be answered and there goes.

    Please provide a particular example, and we might figure out what your problem is.

    I am using the examples that arrived in the instalation CD and I'm trying to comunicate with a java aplication, I realised that c$socket works like a file, and when I make the open it all works fine (the comunication is established) the problem is in the read and writes, no information is passed.
    Thx.

    Note that the read has to be syncronized with a write on the other computer. That is in the nature of sockets, not due to ACUCOBOL-GT. It is hard to indicate anything without any source to relate to.

    Any chance of a small reproducable, or perhaps you should take this with Technical support?

    I was able to get the example from the sample directory working with a simple java program after a suggestion from one of our techies, it required using a port > 1024. For some reason ports below that are handled differently on our AIX system.

    Ports below 1024 are handled specially on all (well, most) systems, UNIX and Windows. They are considered priveleged ports, and only admins/root can establish a socket on such a port. That is a long-standing limitation of sockets in general.

    I'm trying to communicate by the "c$socket" with a www-server at port 80.
    The purpose is to send a html request to a www-server and to receive the answer. Although the answer (of course) is in html format, this is no problem. I only want to filter out a status. The problem is to send the request. If i use a format 'mydomain.com/index.html(crlf)' as string and send it to the server, there will be no response. When I send 2 times 'list' ?? the server response with a html-string with the message ' invalid method in request'. So there is a connection. Can someone tell me if it is possible to send this request and if, how to format the request the www-server will recognise it. Thx.
