Java Servlet Invokation from DCT

Hello All ,

I was able to invoke java servlet from the Data Capture Template (DCT).
But my servlet will fetch some data from the database using that needs
to be displayed on load of the DCT.

But i am not able figure how do i pass data from the servlet to the DCT.

Here is the piece of code i used to invoke servlet from the DCT.

Also attached is the DCT file. Please provide some sample code snippet.

Sample DCT code :

IWEventRegistry.addFormHandler("onFormInit", init);
function init() {
var parameters = new Object();
IWDatacapture.callServer("http://wit31250325:7001/login/myservlet", parameters, true);
# Here i need to access the data retrieved from the database,and display those to the item elements.
# i need to code something like this

IWDatacapture.getItem("/Header-Page/head/title").setValue("value from the database ");

}

Regards,
Sachin

If your servlet and generate / process javascript code - you'd do it the same way you would with a CGI callout. (i.e. RTM: FormAPI Developer's Guide)

Has any one worked on this before. I read the Form Api documentation but did not find it much useful.

I did not understand the concept of ScriptFrame to send data back to the
DCT.
#var scriptFrame = parent.getScriptFrame();
#scriptFrame.myData = "from the server";

Can anyone provide me some code for this.

I just need to find out how do i send the data from then Servlet class to the DCT & populate the DCT item fields.
