Problem in Registartion of XPCOM Component


The component which i was built with gecko-sdk 1.9 (xulrunner-1.9.0.14.en-US.linux-i686.sdk.tar.bz2) on firefox 3.5 But when I tried my component with gecko-sdk 1.9 it fails to register (entry is not appeared in compreg.dat but appears in xpti.dat) on linux.
i take the sample example given in the http://www.iosart.com/firefox/xpcom

but the problem is when i tried to run the application fails with a "TypeError: Components.classes[cid] is undefined" error.


if any suggestion come i will appreciate it.

I'll suggest you don't post the same question twice, within a few minutes of each other.

Re:Problem in XPCOM Component Registration

This is MyComponentTest.js file

function MyComponentGo() {

try {

netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");

const cid = "@nitesh.org/MyComponent;1";

obj = Components.classes[cid].createInstance();

obj = obj.QueryInterface(Components.interfaces.IMyComponent);

} catch (err) {

alert(err);

return;

}

var res = obj.Add(3, 4);

alert('Performing 3+4. Returned ' + res + '.');

}


This is my html file
<HTML>

<SCRIPT SRC="MyComponentTest.js"></SCRIPT>

<BODY>

<BUTTON ONCLICK="MyComponentGo();">Go</BUTTON>

</BODY>

</HTML>

when i m trying to run my html file it is saying
JavaScript Application
TypeError: Components.classes[cid] is undefined


I am followed the same example given in http://www.iosart.com/firefox/xpcom and able to make MyComponent.so file using make file
i also copied my .so and .xpt file to /usr/lib/firefox-3.5.6/components folder.
after that i registered through regxpcom command .but it entry appears in xpti.dat (here interface and .xpt file i found ) but the .so and Components not appeared in compreg.dat)
