Java Development Tools

The last OEPE version that will run on Java 7 is 12.1.3.3.1, which you can find here:

Oracle Enterprise Pack for Eclipse (12.1.3.3.1)

Note that you have to uninstall the newer version of OEPE before you try to install an older one. Else, the older one will not take precedence.

In OEPE 12.1.3.4, we raised the minimum level to JDK 8 to launch Eclipse. You can still use JDK 1.7 (and lower) spec levels for the Java compiler and configured runtimes. Are you able to launch your existing Eclipse with Java 8?

Thanks,

Thanks.  I tried that (I had tried that before) -- Help - Install new software - in 'work with': http://download.oracle.com/otn_software/oepe/12.1.3.3.1/luna/repository/ - expand 'Tools' - check the boxes for 'Oracle weblogic scripting tools' and 'oracle weblogic server tools' .

I still get the same error.  Note: they show as version 7.3.3.201412231459 except for Oracle Java EE Tools which shows as 7.3.4.201502282121  (is this the issue?)

Thanks -

Thanks -- I tried Kosta's suggestion (which I had tried before) but still the same error.

I realized that on my development install (the rest of my team has a year+ old install) that I installed weblogic 12c version 12.1.3 (they have weblogic 12c 12.1.1).  12.1.3 requires jdk 1.8, correct?  I started eclipse w/ jdk 1.8 & no more error.  I added jdk 1.7 (jdk 1.7.0_45) as the default Java compiler in my Eclipse STS (sts 3.6.4; luna 4.4.2). 

When I added a weblogic server instance to eclipse, 12.1.3 would not accept the jdk 1 compiler - it needed java 1.8.  So ... I specified that.

I haven't tried it yet but -- is it ok to compile the code w/ jdk 1.7.0_45 and deploy it to weblogic 12.1.3 that uses jdk 1.8.0_40?

Thanks,

Bill

Oracle Enterprise Pack for Eclipse (12.1.2.4) to Oracle Enterprise Pack for Eclipse (12.1.3.3.1) support Java 7 & 8.

Yes, that would do it. Oracle Java EE Tools is the base component that has Java version detection. You will need to install version 7.3.3 if you want to run Eclipse with Java 7.

If the rest of the team is using WLS 12.1.1 with Java 7, you should not be trying to using WLS 12.1.3 with Java 8, as you run the risk of introducing incompatible code into your shared code base.

Note that the version of Java you run your Eclipse with is completely independent from the version of Java you target with your project. It's perfectly possible to run the latest version of OEPE (12.1.3.4) on Java 8, then target the project to WLS 12.1.1 runtime with Java 7.

Compiling a class with Java 8 and running on Java 7 would generate Unsupported major.minor version error.

This statement is correct, but not relevant to this topic. The latest version of OEPE requires that Eclipse runs with Java 8, but your projects can be configured to compile for any version of Java that's required. When you target a project to a particular WLS installation, OEPE will automatically configure the project to build for the version of Java supported by that WLS version.

All versions of Oracle Enterprise Pack for Eclipse, (12.1.1) and later support Java 7.

The referenced page is incorrect. Thanks for bringing it to our attention. We will fix it.

I have disabled my firewall also.. But not able to install. Please help
