I have sent a email to SunCert, but still got no response from them.
I think I passed SCJD 149/155 marks in Auguest 2003, still I can't recieve the certification. Recently I got a email that I didn't passed SCJD. Cause the website of that SunCert changed a lot , I couldn't find the history page which has the marks and the result they give me , what should I do?
1.Cuz there is no response in my oracle database, server and client when i run my programme, i want to trace the programme in remote EJB. Is there any way to do that like execute client java codes step by step?
2.I am writing my CMP but got some confused about the database key and EJB key class. if i want to create a record , should i use codes in a session bean like this?

should i just set LEGID in Key Class while the other two field should not set to null in database?
Best Regards
try to confirm the relationship in your ejb-jar.xml , maybe it's probably the casesensitive question.
in CMP, it seems that i can't use select max(FIELD) from TABLE in the EJB-QL. any suggestion about pick the max value?
serval days ago , a company give me a question about writing a simple jsp and servlet calling a session bean.

SingalThreadModal allows one thread access the Servelt at one time, it takes effect on Class valiables, it doesn's make new instance of class valiables, but MulitiThreadModal does. Servlet is default as MulitiThreadModal. you can also singal thread by sychronized the codes or methods.

i think i do right deploy them in the file u refer to.

why still can't connect to JMS?
i 'm wondering
i recieved my message in JMS, but can't consume it with MDB. I might think that MDB didn't correctly connect to JMS , what should i put i ebj-jar.xml to right connect to JMS?
i correctly delploy mdb with weblogic in connecting factory and destination name , but in weblogic it can just received my message but can't System.out.println() the code in my MDB. i could see that JMSconnection is false in weblogic. is it necessary? any suggestion about deploy in MDB?
