Hi,
I just installed my MyEclipse 7.5, and encounted this warning when tried to create a new web project:

File -> New -> Web Project lauches the New Web Project window, which list 3 J2EE Specification levels, –Java EE5.0, J2EE 1.4, and J2EE 1.3. The JDK of the MyEclipse 7.5 installation (com.sun.java.jdk.win32.x86_1.6.0.013) is 1.6, the “default compliance setting”. Hence, when I press “finish” at the New Web Project window after choosing Java EE 5.0 (as 6.0 is not listed here), I was given a warning message: “Compiler compliance level of proj HelloWebProject should be 5.0. Your current workspace default is 6.0. Do you want to use a custome setting for your project?”. A Web project was created regardless Yes or No was entered to the question prompt.

How can set the complier compliance level to the JDK 1.6? If I can only choose among the 3 J2EE Specification levels (i.e., Java EE5.0, J2EE 1.4, and J2EE 1.3), where is the JDK directory of the MyEclipse 7.5 installation that matches my choice of say Java EE5.0 or J2EE 1.4? –Currently, I have my tomcat installation pointed to Java EE6.0 (com.sun.java.jdk.win32.x86_1.6.0.013) of the MyEclipse 7.5 installation. It makes sense if all my Java code uses the same compiler Java 6.0.

Thanks so much,
Chunhua

The JEE profile level is different from the JDK level.

com.sun.java.jdk.win32.x86_1.6.0.013

That is the Java 6 JDK.

the New Web Project window, which list 3 J2EE Specification levels, –Java EE5.0, J2EE 1.4, and J2EE 1.3. …

How can set the complier compliance level to the JDK 1.6?

Chunhua,

AS per Ray, JEE specification is different from JDK level.

I would recommend you to follow the below steps to set the complier compliance level

1) Create new web project.
2) After you click “Finish” button in “New Web Project” Wizard, a warning dialog box will be displayed. Click “Open Workspace Compiler Settings” link.
3) Compiler Preferences page will be displayed.

You can change Compiler compliance level to your required level.
