I am relatively new to Java development. I have a couple of questions: 1. How do I know the version of Eclipse Java EE installation? 2. How do I upgrade to a newer version say Java EE 7.
Regards, Janet T.

The White Bullet answer is related to Java version, if you're talking about Java EE, the version will depend on your container (JBoss/Wildfly, WebLogic, Glassfish, etc...). Just choose one Java EE container and the version of it will define the Java EE version, for example, Wildfly 10.0.0.Final is intended for Java EE 7
Your eclipse config file should indicate which java version eclipse is running on. This is normally specified by the '-vm' tag, as it indicates which directory eclipse is using to look for the java.exe file.
To upgrade to a newer version, you can download it from the Oracle website and then point the '-vm' to the directory where you installed the downloaded version. You can have multiple java versions installed on your machine. The one specified in your JAVA_HOME system properties is the one that is normally used to build your jars if building from the command line.
