Hi!
I cannot make any custom component to be loaded in either Mozilla 1.7
release or Camino debug (built from yesterday's CVS). This includes my
own attempt as well as nsSample (@mozilla.org/sample;1).
This is what I do:
1) create symlinks for xpcomsample.xpt and libxpcomsample.dylib in
Mozilla/Contents/MacOS/components (or copy them, doesn't matter)
2) launch Mozilla
3) open xpconnect-sample.html
4) nothing happens as I press the buttons that are supposed to call
the sample code. If I add a try/catch block around the code, this is
what I get in onLoad:
[Exception... "Component returned failure code: 0x80570015
(NS_ERROR_XPC_CI_RETURNED_FAILURE) [nsIJSCID.createInstance]"
nsresult:
"0x80570015 (NS_ERROR_XPC_CI_RETURNED_FAILURE)" location: "JS frame ::
file:///Volumes/Work/test.html :: OnLoad :: line 10" data: no]
I have tried deleting compreg.dat and xpti.dat and restarting the
browser. I have also tried loading the component from xpcshell (and
got the same error).
When I look at the components in question with Component Viewer, their
ContractIDs and interfaces are present, but seem to be not linked to
each other (i.e. if I click on the disclosure triangle near the
ContractID, nothing appears).
The component seems to get registered OK:
*** Registering nsSampleModule components (all right -- a generic
module!)
I tried running Camino in the debugger and found that the failure
occurs in XPCOMGlueStartup("."), called from:

It returns just 0x80004005 (NS_ERROR_FAILURE).
All components installed with Mozilla or Camino are loaded and
created just fine with the same code; it's just nsSample and my own
component that fail. What am i doing wrong?
