Re: [higgins-dev] configuration changes committed

Hi Jim,

I went through your configuration file and identified the problem:

<Setting Name="JNDIContextFactory" Type="htf:classinstance">
org.eclipse.higgins.idas.cp.jndi.JNDIContextFactory</Setting>

should be defined after defining the configuration settings for the context
factory, i.e. after the 'ComponentSettings' section.

Also the IdASRegistry is identified by the setting name
'IdentityAttributeService' in the configuration file and not as
'IdASRegistry'.

Thanks,
Best regards,
Rajalakshmi Iyer

Greg,

We're having problems with this new code.  I've tried fixing a few things,
but I find myself without the knowledge of what the intent of a lot of new
code is, so I think my fixes are causing further problems.



For example:



ClassInstanceHandler.getComponentMap throws a NullPointerException on this
line:
>if ( componentsDescriptor.getName().equals(componentName)) {



It's because componentsDescriptor is null.  that's because a bit further
down, in the while loop, we assign settingDescriptor =
componentsDescriptor.getSubSetting(key) (which in one of the iterations
returns a null) and pass settingDescriptor back into the recursion as the
new componentsDescriptor.



I don't know if that case is simply unaccounted for, or if it's a problem
with the config (attached).  All I know is "it used to work".  As a
workaround, I did this at the top of the function:
if (componentsDescriptor == null) {
log.debug("componentsDescriptor is null. Map: {" + componentsMap + "}
componentName: " + componentName);
return (Map)componentsMap.get(componentName);
}



here's a chunk of output that u can match to the settings file:
18:48:37,131 DEBUG MapHandler.getSetting (57): Setting Name:

18:48:37,131 DEBUG MapHandler.getSetting (57): Setting Name: IdASRegistry

JNDIContextFactory
18:48:37,147 DEBUG ClassInstanceHandler.getComponentMap (37):
componentsDescriptor is null. Map: {{}} componentName: JNDIContextFactory



I only halfheartedly believe my change was the right thing to do from
looking at the old code.  But now I'm getting a NullPointerException in
IdASRegistry.registerContextFactory on this line:
for (int i=0; i< types.size(); i++) {
because types is null.  So I'm assuming something didn't get read in
correctly.



Any ideas?

I think that I've managed to commit all changes that are needed to cope
with the
Configuration API modifications for dynamic updates to IdASRegistry.  If
I've
broken one of your favorite projects, please let me know and I'll try to
fix it.

This should allow us to close Bugzilla #238374.

...Greg
