In the repos, I see openJDK 1.7 and 1.8 but for a project I’m working on, I need 1.6. I looked on software.opensuse.org but couldn’t find it there for LEAP. Where can i find this for install?
That’s extremely old, imo there are 2 posibilities
#1 build openjdk yourself from source
get the source here
https://java.net/projects/openjdk6/downloads/
and compile
#2 use a binary for an older opensuse build, the latest I could find was for opensuse 12.1

http://ftp5.gwdg.de/pub/opensuse/discontinued/distribution/12.1/repo/oss/suse/x86_64/java-1_6_0-openjdk-devel-1.6.0.0_b22.1.10.4-1.2.x86_64.rpm
or try the source rpm from 12.1
http://ftp5.gwdg.de/pub/opensuse/discontinued/source/distribution/12.1/repo/oss/suse/src/java-1_6_0-openjdk-1.6.0.0_b22.1.10.4-1.2.src.rpm
see this link about how to build openjdk under opensuse
https://github.com/hgomez/obuildfactory/wiki/How-to-build-and-package-OpenJDK-7-on-Linux#opensuse--sles
that link is for 1.7 but with a little tweaking it can be used for 1.6
if it was me I’d try building from the source rpm as it has a ready to use spec file, just install the needed dependencies and use rpmbuild
Thank you, there is a repo I found: http://download.opensuse.org/repositories/Java:/Factory/openSUSE_42.1/x86_64/
