CallServer function to a different domain?

G'day,

Edit: Using TS 7.3.2....

trying to get the callServer function to work to dynamically populate a drop down list of department names. I implemented a servlet to query a database and return the proper embedded JS code for the callServer function.

I believe i'm running into a cross domain issue however, since my servlet is not hosted on my teamsite server. I couldn't really find anywhere in the FormAPI documentation where it explicitly mentions this.

A search on devnet pointed me to this workaround, using external_proxy_remap in iw.cfg

https://support.interwoven.com/kb/kb_show_article2.asp?ArticleID=49824

But can't seem to get this working either... I don't get an error visually in the DCT, but the drop down simply doesn't populate. Having a heck of time locating a log file where an error could point me in the right direction.

Here's what i have configured in my iw.cfg file, based on the workaround in the devnet link above:

[iwproxy_external_remap]
_regex=^/iw-mount/default/main/branch/workarea/iwformcalloutdata\.do$=http://my-server/iwformcalloutdata.do

And my callServer script:

var parameters = new Object();
parameters.mthd = "dptOptions";
IWDatacapture.callServer("http://my-server/iw-mount/default/branch/workarea/iwformcalloutdata.do", parameters, true);

any ideas?

Have you tried running the iwproxy in debug mode to see how it's rewriting your request? (The article even mentions this). If not, use iedevtools/firebug/chromeinspector to trace the http call and see what comes back.

Also note that your callServer() should be calling http://teamsiteserver/ and not the servlet server. You had "my-server" in both places so it's hard to tell if you got that part right.

ah yes... i hid the server names. But indeed, i'm calling the TS server in the callServer.

running iwproxy in debug reveals a 404 response from the origin server, which in this case I assume is my TS server.

Does my remap rule need to point to a physical file? Or does the iwproxy simply use it as a lookup in the proxy rules to redirect me to external server?

I obviously dont have a file located in that branch called iwformcalloutdata.do....

Rick Poulin

No, the file doesn't need to exist. The rules should rewrite the request before it even checks the "fake" location.

After looking at debug output a few times, using iwproxy -d -x... saw that proxy remap regex was not matching, since i wasn't specifying the parameter... my callServer script was appending a parameter to the URL.

Adding the parameter to the remap regex got it working.

Good stuff. You'll probably want to make it more generic now, so that things like parameters and other contexts don't trip you up in the future. Something like

_regex=^/iw-mount/.*/iwformcalloutdata\.do(?.*)?$=http://my-server/iwformcalloutdata.do$1
