cfscript

[bikerboy]

since i cannot find the cf and java integration thread, gues i will post this
here: i wrote a cfm with cfscript that utilizes java which connects to a
socket on another server. everything is working, but i would like to add a
timeout. we are still on cf5 so i cannot use the try/catch in cfscript. if i
would like to init setsotimeout, any ideas on how or where it would be placed?
i have an example of my code posted thanx for any help!!

<cfscript>
// create the Java object Socket to connect with TCP
socket = CreateObject("java", "java.net.Socket");
// javacast the IP address to string for Socket
SevIP = javacast("string", "10.10.10.10");
// javacast the Port to an Int for Socket
SevPort = javacast("int", 4000);
// call the Socket object (cf utilizes init())
socket.init(SevIP, SevPort);
// get the IP address from the socket connection (this will verify that you
are connedted
SevGetIP = socket.toString();
// get the port in which you are connected to
SevGetPort = socket.getPort();
// close the socket (if you do not do this, it will lock
the socket and port so that no other user may
// connect)
socket.close();
</cfscript>

well you could wrap the whole cfscript in a cftry/cfcatch block. as for the timeout, can't you do a socket.setSoTimeout(100); ?

i tried that, but nada. it just goes to the same exception error. i need it to
close the socket, and send a nice message to the user that the server is
currently unavailable (or something to that fact). thanx sean

tried what? something like this?

<cftry>
<cfscript>
// create the Java object Socket to connect with TCP
socket = CreateObject("java", "java.net.Socket");
// javacast the IP address to string for Socket
SevIP = javacast("string", "10.10.10.10");
// javacast the Port to an Int for Socket
SevPort = javacast("int", 4000);
// call the Socket object (cf utilizes init())
socket.init(SevIP, SevPort);
// set timeout
socket.setSoTimeout(100);
// get the IP address from the socket connection (this will verify that you
are connedted
SevGetIP = socket.toString();
// get the port in which you are connected to
SevGetPort = socket.getPort();
</cfscript>
<cfcatch type="java.net.SocketException"> <!--- or maybe Any --->
<!--- close the socket (if you do not do this, it will lock the socket and
port so that no other user may connect) --->
<cfset socket.close()>
</cfcatch>
</cftry>

i had just worked on the cftry-catch and that did the trick. i was thinking that it needed to be internal with the cfscript (like with the newer versions of cf).

golden!
thanx

um, don't forget logic to close the socket if everything went ok & the connection is no longer needed.

[bikerboy]

yep, just for the heck of it, i attached my test code. thanx again!
