Replacement for Java 8.0 to setup I2B2 Server and Databases

[Ashish Pagare]

We are setting up our Development environment for I2B2 and while following throught he instructions here:  https://community.i2b2.org/wiki/display/getstarted/2.4.1+Java+JDK, we noticed that we need to download Java 8.0 or 11.0 (More details below).

Both these versions of Java are no longer supported by Oracle andour Info. Sec. team is against us using these even though we are just setting up our development environment at this time.

I am interested to know how other organizations overcome this limitation. Thanks in advance.

Required Version: Java 8.0 or 11.0

Download from Website: http://java.sun.com

Click the link for "Java SE 8u411" or "Java SE 11.0.23 (LTS)", select your operating system, and download the file.

Latest i2b2 supports JDK 17 and wildfly 34.0.1. We have been using this configuration in our environment for a long time.

Regards,

Saber

Thank you, Dr. Saber. Did you acquire a license for Java from Oracle? We learned the Oracle charges Java license by each user. 

Is there any organization using OpenJDK to overcome license cost from Oracle? 

PS: The documentation on i2b2 website needs to be updated. I am happy to take charge on this once we finalize the details. 

Thank you.

Hi! 

i2b2 may not officially support JDK 17, but we installed OpenJDK 17 with some updated packages for security assessment. It's running without any issues. We built our environment with amazonlinux:2, openjdk 17, wildfly-34.0.1 in a docker container

Thanks,

Saber

Thank you so much. We will do the same setup in our environment with OpenJDK 17. 

Thanks

Hi Saber,

I attempted to use Ubuntu 24.04 + OpenJDK 17 + Wildfly 34 and ran into an error starting the service.  Wildfly 17 worked for me.  The error is pasted below.  Did you have to make any modifications to make a newer Wildfly version work?

Officially updating Wildfly and Java compatibility should be a priority.

The current version 1.8.1 works with either Oracle Java or OpenJDK.   The official website said JDK 8 with Wildfly 17.   But it works with JDK 17 and Wildfly I think 27, any version I believe after that does not work.

 

The new version 1.8.2 coming out soon will work with Java and OpenJDK 17 and Wildfly 35.  The axis2 has also been updated to the new 2.0

 

The reason you are getting that error below is because axis2 1.8 does not work with Wildfly 34.
