Tagged: WebSphere bug MyEclipse java8
December 29, 2017 at 9:50 am #546172
Our company is using WebSphere 18.104.22.168 which supports JDK 1.8 as a fix pack. The JDK is added to the WAS installation as a folder name java_1.8_64. I set the WAS8 jdk as that folder and everything works fine until I restart Myeclipse. When I do that the jdk folder changes from AppServer\java_1.8_64 to AppServer\java. If the jdk is pointing to the wrong folder we are unable to start new web projects, add WAS 8 as a runtime to replace WAS 7, etc. We have around 70 users and are currently moving to this version of Websphere, so the bug is kind of an issue.
Any way for us to fix this besides changing the JDK directory every time we start MyEclipse?

Sorry that you are seeing this issue. We are looking into this problem and we will get back to you soon.
In the meantime, can you please let us know if there are any additional steps apart from just copying the Java 8 folder to the AppServer? Also share with us your OS and version details. If you are not working with the latest MyEclipse 2017, then please share with us the version of MyEclipse you are working with.
Apologies for inconvenience caused.

To get WebSphere 8 working, we applied the patch and added the SDK to allow JDK 8 provided by IBM. Their patching tool created the \java_1.8_64 folder. In later versions of WAS8.5, JDK 8 is the default and is located in the default \java folder.
The only thing I do is change the location of the Installed WebSphere JRE, after eclipse is restarted, the JRE folder changes back.

Thank you for the details. I could replicate the problem at my end. I have raised a bug for the dev team to investigate it further. I am afraid I cannot suggest any other workaround at this point of time apart from the obvious: renaming the original ‘java’ folder to something else and java_1.8_64 folder to ‘java’.
Thank you for reporting this problem. We will keep you posted when we have any other suggestions from the dev team and will also let you know about the fix schedule.
Apologies for inconvenience caused.

Thanks for looking into this. It doesn’t seem like changing the folder name is a viable solution as the server has those folders mapped in its configuration and would require changing multiple environment variables in the WebSphere configuration. I will make our users aware of the issue.

The way to change the JRE used is to alter the runtime configuration, rather than the launch configuration. So, on the server configuration editor, click the “Runtime Environment” link, rather than the “Open launch configuration” link. Pulldown the Configured JRE list and select the one you want. This will be the JRE used for the Websphere runtime.
We will also look at the launch configuration, as Swapna mentioned. At the very least, it should not appear to give you the option to change the JRE. That tab, in the launch configuration, takes its JRE from the runtime environment.
Sorry for the confusion with this; we will look at tidying this up.
Please let us know how you get on.
