Thanks for your suggestion.
While running the simple run/java demo i got the following error suggesting that socket plugin is not found during init and some more warnings.
i have used kernel=hw and BOARD=virt_qemu_arm_v7a


Kindly give some advice on how to proceed further.

Best,
YAMINI.

Dear Genodians,

I am writing to you to request your guidance on porting OpenJDK to run
simple java programs in Genode. As I have been looking into the
possibilities of running OpenJDK on Genode.

I have been searching for documentation and resources on the subject, but I
have not been able to find any comprehensive guide that explains the
process in detail.

Could you please guide me on the steps involved in porting OpenJDK to
Genode?
Additionally, if you know of any resources or documentation that could be
useful for me, I would be grateful if you could share them with me.

Thank you very much for your time and consideration.

Best regards,
Yamini

There is a port of OpenJDK 9 in our world [1] repo. It runs on x86_64 and
arm_v7. You can test drive a simple hello using the java.run script, e.g.,

make KERNEL=linux BOARD=linux run/java

Sebastian

Hello Yamini,

An OpenJDK port already exists in the genode-world repository
(https://github.com/genodelabs/genode-world).

Best regards,
Timo
