问题
I have EAR file (which includes a WAR file and EJB jar file) was deployed on Web-Logic(10.3.6) successful.
Now, I have updated EAR file and I redeploy again follow steps: delete old files on the server and install new EAR file without restart server. Every file have been deployed in Active state. But I got some exception related EJB injection. Then I restart Web-logic, my app is running fine.
What's wrong with the redeploy way?
Thanks in advance for any Help...

Weblogic has an lots of documentation about this topic. Sometimes it's referred to as a "hot deploy" or an "in-place" deploy. In the weblogic admin console there is an option to update an ear file rather than what you are doing with the delete->redeploy method.
Just make sure to update your Weblogic-Application-Version property in the MANIFEST.MF of your ear so that weblogic knows it's a new version. Here are some useful links:
Oracle redeploy documentation
An older but still valid list of steps to hot deploy
That said - the problem you are seeing may be something different and your question will need to be updated with more details if the Oracle docs don't help.
