How can avoid OpenJDK?

[masch]

Hello,

Can I install LibreOffice without installing OpenJDK package?

Thanks!

You sure can, but that would entail installing from source or some not endorsed repo, I'm afraid. Anyway, AFAIK OpenJDK does not get in the way of Sunacle Java. Any specific issues?

Thank for you reply. No, I do not have any particular issue, but since I work with severals Java framework I do not have installed OpenJDK virtual machine, sometimes I get some issues on those framework with OpenJDK that work fine on Oracle JDK virtual machine.
So, since I am not installing OpenJDK virtual machine I cannot install LibreOffice from Fedora Repository?

I am afraid not

[root@localhost ~]# yum deplist openoffice.org-core|grep jdk
   provider: java-1.6.0-openjdk.i686 1:1.6.0.0-44.1.9.1.fc14

This is for openoffice on F14, but I guess it's going to be the same for LibreOffice on F15. Anyway, you really should not experience any issues having both OpenJDK and Sunacle Java installed on the same system. I too use frameworks like Eclipse and JBoss with Sunacle Java and they are working fine. In fact, I keep OpenJDK only to support Fedora's OpenOffice. If you follow the instructions here or use DM's FedoraPlus you shouldn't experience clashes between the two versions of Java

A few month ago I had some issue with it, I will try it again...

Thank you for your help1

well, libreoffice-core doesn't specify a specific java package. It has dependencies on various things provided by java:

libjawt.so()(64bit)
libjawt.so(SUNWprivate_1.1)(64bit)
libjvmaccessgcc3.so.3()(64bit)
libjvmaccessgcc3.so.3(UDK_3.1)(64bit)
libjvmaccessgcc3.so.3(UDK_3.4)(64bit)
libjvmfwk.so.3()(64bit)
libjvmfwk.so.3(UDK_3_0_0)(64bit)

are the ones I can see. So if you had an RPM package of a different Java implementation which provided all those things, libreoffice would be happy with it. If you install the other Java through non-RPM means, or if it doesn't provide the same capabilities as the Fedora OpenJDK package, though, it won't satisfy the dependencies.

Yes. Just install LibreOffice, including OpenJDK that get pulled in as a dependency, then use rpm to force the removal of OpenJDK:

rpm -e --nodeps java-1.6.0-openjdk

I've done this before and never had a problem. The Sun/Oracle JDK works perfectly as a replacement if you have that installed. When updates occur, which will reinstall OpenJDK, just repeat the above procedure.

There's no reason why you can't have many Java JDK's or JRE's installed at the same time. If openjdk causes a problem you don't have to use it, just use the alternatives tool to point your system java to the 'good' one like Sun/Oracle 1.6.0.25. You can configure LibreOffice to use a particular JDK.

Assuming Oracle java is installed in /usr/java/default, and you want to use that, but still have openjdk installed:
/usr/sbin/alternatives --install /usr/bin/java java /usr/java/default/bin/java 20000
/usr/sbin/alternatives --install /usr/bin/javac javac /usr/java/default/bin/javac 20000
