Re: component registration problem? (pyxpcom)

Christoph,

I have no idea if this might be the cause but for the last few Firefox and Thunderbird builds I have had major headaches registering new JS components, my understanding is because they have started adding some stuff into user profiles as well.

My process is now as follows:

In /components/

Delete 'compreg.dat' & 'xpti.dat'

In the userprofile directory

Delete 'compreg.dat' & 'xpti.dat'

Drop the component and XPT files into /components/

Then run 'regxpcom -a'

BTW. Component Viewer although so slow it hurts is a great XPCOM utility for checking out your components and interfaces are registering correctly. It's up on mozdev somewhere.

Cheers,

Neil

dear list,
i am not able to register my pyxpcom component successfully. at first i have copied the xpi- and the py-file to the /components-directory and ran ./regxpcom. but whenever i tried to load it with xpcshell, i got the message that my component (@umc/nsIUmcTest;1) is not registered ("Invalid ClassID or ContractID").
(btw: i had no troubles registering and using a c++ and a js-component).
so i checked the registry-files (components/*.dat) and compared to the files in the Komodo-directory (Komodo also uses pyxpcom), and it seemed that regxpcom was not able to register the python library. that's not really a problem as i can register the components manually, so i added the following lines:
components/compreg.dat:
[CLASSIDS]
{ce32e3ff-36f8-425f-94be-d85b26e634ee},,script/python,,rel:nsIUmcTest.py
[CONTRACTIDS]
@umc/nsIUmcTest;1,{ce32e3ff-36f8-425f-94be-d85b26e634ee}
in components/xpti.dat there's the following line (generated by regxpcom, i guess):
[Interfaces,989]
630,nsIUmcTest,{ce32e3ff-36f8-425f-94be-d85b26e634ee},120,-1,1
now when i run xpcshell, i no longer get the "Invalid ClassID or ContractID" error message, but the following error:

[EMAIL PROTECTED]:~/umclaw/mozilla> ./run-mozilla.sh ./xpcshell js> const Simple=new Components.Constructor("@umc/nsIUmcTest;1", "nsIUmcTest"); js> var s=Simple(); :2: Component returned failure code: 0x80570015 (NS_ERROR_XPC_CI_RETURNED_FAILURE) [nsIJSCID.createInstance] js>

i have no idea what this error means, maybe one of you has a hint? i really want to get this working...
thanks,
Chris
