Problems using java client against karaf/hawtio hosted Jolokia

[Stefan Larsen]

Hi
I have modified the JolokiaDemo java class slightly to make it use the correct url and username/password, but I keep getting "org.jolokia.client.exception.J4pRemoteException: Forbidden"

The only modification I have made is how the J4pClient is created:
        J4pClient j4pClient = J4pClient.url("http://localhost:8181/hawtio/jolokia").user("karaf").password("karaf").build();

I can connect using curl without problems:
curl -su karaf:karaf http://localhost:8181/hawtio/jolokia/read/java.lang:type=Memory/HeapMemoryUsage
{"timestamp":1400769276,"status":200,"request":{"mbean":"java.lang:type=Memory","attribute":"HeapMemoryUsage","type":"read"},"value":{"max":518979584,"committed":133644288,"init":134217728,"used":56233064}}

I am trying to reach a Jolokia in Hawt.io 1.4.0 running in Apache Karaf 3

Any help appreciated ;-)

Cheers,
Stefan

The problem is, that hawat.io used as karaf feature doesn't do plain Basic Authentication, but has more complex initial handshake.

I opened an issue: https://github.com/rhuss/jolokia/issues/141 The implementation for this is already finished, in the meantime you could create an HttpClient on your own and send an empty POST request to /hawtio/auth/login with the Header 'Authorization' set properly as for BasicAuthentication. Then you receive a session Cookie which needs to be used for the Jolokia Request.

I'll come back as soon as the implementation is finished. This will go into 1.2.2

Great!

I will try your tip and keep try 1.2.2 when it comes.
Thanks for helping on this :-)

Cheers,
Stefan

FYI, I just posted a possible (though untested) workaround over there at the Github issue.
