I am writing a custom authenticator which require to lookup datasource from JNDI at startup. I got NameNotFoundException error during startup 

[2017-02-25 12:01:39,071] [Component Resolve Thread] ERROR {com.kbank.carbon.identity.authenticator.KBankAuthenticator} -  Exception while looking up datasource[jdbc/API_SERVICE_DB]

I looked up the data source using following code.

DataSource dataSource = (DataSource) new InitialContext().lookup(dsName);

If I moved this code from static block/constructor and put inside a method, it works fine.

I think it is because my custom authenticator was loaded before JNDI (or JDBC) features. How can I make my custom authenticator lookup datasource from JNDI during startup.

Thank you very much.

  • How do you lookup the data source? Can you try with this. http://stackoverflow.com/a/4099163/3176125 – Pubci Feb 25 '17 at 10:18
  • Thank you for your suggestion, I have look at the link you provided but it is not related to my problem. In my case I got exception only when I put the lookup code inside static block/constructor but worked fine if I use same lookup inside a method. Since in WSO2 the code is deployed as OSGI bundle so I think it is the problem with bundle load order. – tinnapat Feb 25 '17 at 10:36
