What to expect for hiring a fresh java engineer?

I was in the process of hiring fresh java candidates for my team. During the process most of the time the guy who could answer well in technical personal/phone interview could not do well in the written test. And who did average in personal/phone interview was able to score better in the written test.

Should I have to go with the my intuition or should I have to follow what was put on the paper? Still haven't found the answer. After a deep thought I came up with few points to consider while hiring a fresh java engineer.
  1. Do not even ask questions from what he doesn't know. (JavaAPI is big and can not expect any one to remember each and every class and methods of it.)
  2. Instead find that he really understands what he knows or is he a book worm.
  3. Ask yourself whether he/she can fit well into my team and can he/she get the work done.
  4. Look whether the candidate is good at problem solving. Programming is all about problem solving so give a business problem and try to check how solves it.
  5. Does he has a good communication, grasping and able to explain the concepts which he knows well.
  6. Does he/she loves programming or he wants a job desperately.
I am sure I have left lot of other aspects to be considered, but still the above 6 looks very important to me. What are your thoughts?

P6Spy Open Source Framework to detect database performance bottlenecks in Java applications

What is P6Spy?
P6Spy is an open source framework for applications that intercept and optionally modify database statements. The P6Spy distribution includes the following modules:
  1. P6Log. P6Log intercepts and logs the database statements of any application that uses JDBC. This application is particularly useful for developers to monitor the SQL statements produced by EJB servers, enabling the developer to write code that achieves maximum efficiency on the server. P6Spy is designed to be installed in minutes and requires no code changes.
  2. P6Outage. P6Outage detects long-running statements that may be indicative of a database outage proble and will log any statement that surpasses the configurable time boundary during its execution. P6Outage was designed to minimize any logging performance penalty by logging only long running statements.
P6Spy includes installation instructions for JBoss, ATG, Orion, JOnAS, iPlanet, WebLogic, WebSphere, Resin and Tomcat.
