java - Error implementing the Thrift API -

-

i'm implementing thrift remote procedure call framework in java. set thrift , generated skeleton code without lot of issues, i'm using api methods, strange errors.

here errors get: 

exception in thread "main" org.apache.thrift.transport.ttransportexception: cannot write null outputstream @ org.apache.thrift.transport.tiostreamtransport.write(tiostreamtransport.java:142) @ org.apache.thrift.protocol.tbinaryprotocol.writei32(tbinaryprotocol.java:163) @ org.apache.thrift.protocol.tbinaryprotocol.writemessagebegin(tbinaryprotocol.java:91) @ simonsays$client.send_registerclient(simonsays.java:102) @ simonsays$client.registerclient(simonsays.java:96) @ simon.main(testclass.java:16)

i don't think i'm not making mistakes, make sure, here's code that's leading errors: 

tprotocol prot = new tbinaryprotocol(new tsocket("http://thriftpuzzle.facebook.com",9030));     simonsays.client client = new simonsays.client(prot);      client.registerclient("useremailaddress@gmail.com");

the error said generated client.registerclient() call, call code generated thrift, makes me feel i'm doing wrong in setting connection itself.

the part making tprotocol instance included myself, , it's that's problem lies.

i hoping have more of idea what's going wrong do.

please let me know if more information or clarification needed.

edit: found tprotocol instantiation statement cassandra wiki

you need call open() method on tsocket instance in order connect , obtain input/output streams needs.

source: tsocket.java
