Recently I tried to use Eclipse but when I open it,it told me my JVM verion is too old
Incompatible JVM
Version 1.5.0_05 of the JVM is not suitable for this prod
This happen when you have another java version installed in your S.O. and the path to this version stay in "Environment Variables"."Path". So, remove any path that is pointing to another old version of java. In my case, i have oracle Forms6i installed in my S.O., and the installation program putted the path to the java 1.4. In my case the path was: C:\oracle\product\10.1.0\Client_1\jre\1.4.2\bin\client; C:\oracle\product\10.1.0\Client_1\jre\1.4.2\bin;
To access "Ambient Variables" no windows, right click mouse button on "My Computer" -> "Properties". On the left side click in "Advanced System Settings", on the top, click in the guide "Advanced", then click in the last button on the bottom, "Enviroment Variables". On the bottom have "System Variables", search for "Path" and do what i said there on top.
