Cannot get Custom Attribute Finder to appear in WSO2 Identity Server Console - wso2

Question

I did some development of a custom AttributeFinder for WSO2 4.6 several years ago, and I am trying to reproduce that old development on one of my original WSO2 4.6 instances, but I cannot get the AttributeFinder to appear in the WSO2 IS Console in Extensions. I know that 4.6 is old, but I just want to get this working with 4.6 first.
I've built the AttributeFinder in Eclipse successfully
Put a copy of the JAR in E:\WSO2\wso2is-4.6.0\repository\components\lib
Put copies of ojdbc6.jar and classes12.jar into E:\WSO2\wso2is-4.6.0\repository\components\lib
[This AttributeFinder is supposed to get the attributes from an Oracle DB]
I've updated E:\WSO2\wso2is-4.6.0\repository\conf\security\entitlement.properties by adding:
PIP.AttributeDesignators.Designator.3=my.myAttributeFinder
my.MyAttributeFinder.1=databaseUrl,jdbc:oracle:thin:#//192.168.0.xxx:1521/xxxorcl
my.MyAttributeFinder.2=userName,hr
my.MyAttributeFinder.3=password,XXXX
my.MyACAttributeFinder.4=driverName,oracle.jdbc.driver.OracleDriver
my.MyACAttributeFinder.5=dbTableName,DB_FILTERS
Then I restarted the WSO2 but when I got into the console and look at Extensions/Attributes, it is only showing the default attributes/attributefinder.
As I said, I had this working awhile ago, so I'm sure that the code I used to build the attribute finder class/jar is ok, and the lines I had to add into entitlement.properties above are ok, but it just looks like WSO2 IS doesn't even "know" that I have a custom attribute finder installed, so I think I must be missing some step or something.
Can anyone tell me what else I need to get WSO2 IS to "see" my custom attributes?
Thanks,
Jim

Answer 1

I just figure out what the problem was. I had added my lines to the default, out-of-box entitlement.properties, and in particular, I had the Designator line:
PIP.AttributeDesignators.Designator.3=my.myAttributeFinder
In the default entitlement.properties, there was already only one other PIP Designator lines, something like:
...Designator.1=...
What I didn't realize is that, apparently, the Designator numbering has to be sequential!
So, when I changed the line to:
PIP.AttributeDesignators.Designator.2=my.myAttributeFinder
instead of:
PIP.AttributeDesignators.Designator.3=my.myAttributeFinder
Then, the WSO2 IS picked up my custom finder ok!
