Re: LiveConnect to XQuery/Berkeley DB XML

Hi,

Yes, thanks, I got it fixed and working now... I've also posted a couple 
of other smaller issues needing fixing which I can repost here:

1) Why does a try-catch not work on a Java method (putDocument for 
BDBXML) as it is supposed to according to 
http://developer.mozilla.org/en/docs/Core_JavaScript_1.5_Guide:LiveConnect_Overview:JavaScript_to_Java_Communication#Handling_Java_Exceptions_in_JavaScript
This is pretty necessary if doing things like dynamically putting in 
documents (or adding Containers for that matter) which might already 
exist with that name, etc.

2) Have I limited the .java.policy file's permissions sufficiently? Can 
I be more strict without losing needed functionality by BDBXML? I 
presume it shouldn't be too much of an issue since the unrestricted 
permissions only exist for those two jars which I've installed myself...

Here's my file:

grant codeBase "file:///C:/Berkeley DB XML/jar/dbxml.jar" {
permission java.security.AllPermission;
};
grant codeBase "file:///C:/Berkeley DB XML/jar/db.jar" {
permission java.security.AllPermission;
};

3) Is there any way to specify the DLL locations for Firefox external to 
the Firefox folder (so that if other users wanted to install it, they 
wouldn't need to copy the DLL's to the Firefox folder I could just have 
the JS save them that work... Also whether it'd be possible to specify a 
.java.policy file within the extension folder or the like, so people 
wouldn't have to manually create one or move that around either...
