OIM Custom ICF based connector throwing runtime exception

Question

I have created one ICF based Flat file connector which uses REST web service to Read/write the data from file. I have used jersey implementation 1.6 to write the web service and the java client which will call that web service.

I am using stand alone java code for testing the CRUD functionality.It's giving exception at first line where I am initializing the jersey Client.

Client flatFileRestClient = Client.create();

I got to know that the error is because the connector server is not able to recognize the jersey implementation jars.So as per documentation of ICF connector i had put the jersey bundle jar in connector server/lib folder. I had restarted the connector server and invoke create operation but issue still exists.

I had also added the class path of custom jar in ConnectorServer.bat file located in CONNECTOR_SERVER_HOME/bin. Still the issue persists.

Please find full stack trace of the exception thrown on eclipse console:

Any help at the earliest would appreciate.

can you try the client code without connector server? and let me know the results? — Chaitanya K, Jun 07 '16 at 05:42
Thanks Chaitanya Yes the custom Java client is working fine. It's reading/writing the date from/to file. — Kunal Varpe, Jun 07 '16 at 06:41
I have not crated the OIM metadata for the connector. Right now i am building the connector code only. — Kunal Varpe, Jun 07 '16 at 06:43
Does that mean your query is resolved ? or you need to try it once you are done with the Metadata thing? — Chaitanya K, Jun 07 '16 at 07:18
I see the issue is more with the jersey jars as the error thrown on connector server was classNotFound. I would trying that bce OIM metadata is ready. But wanted to know why that is not working standalone java code. — Kunal Varpe, Jun 07 '16 at 07:42

The problem was due to the REST API jars which i was using. I have de-compile the jersey-bundle-1.6.jar and found the javax.ws.rs.ext.Providers.class is not present in that jar. So i have downloaded the Java 6 complied version of the Jersey-bundler-1.16.jar
