How Can I Specify a 32bit JRE for zdesktop 7.2.8 [FIXED BY WORKAROUND]

Postby themetman » Wed Aug 31, 2016 10:56 am

I have had the same problems with 7.2.8 install as others, and just commented out the java_check() in the install.pl
I did try using Oracle as well as openjdk, but same error.... JRE not found!!!
I am running CentOS 7 64bit, and the old 7.2.7 worked before upgrade of zcs to 8.7 when zdesktop accounts would not connect any more.
To get rid of most error messages I installed the following:-

Code: Select all

yum install glibc.i686 libstdc++.i686 xulrunner.i686 gtk2-engines adwaita-gtk2-theme.i686 PackageKit-gtk3-module.i686

When I try and run the program from the command line I just get the waiting circle going round and round.
Now in the log I get:

Code: Select all

STARTED Jetty Wed 31 Aug 09:52:26 GMT 2016
Error: This Java instance does not support a 32-bit JVM.
Please install the desired version.

Am I right in thinking that if I could run zdesktop in a 32bit JRE it might work?
I added

Code: Select all

 env JAVA=/opt/java_i586/jre1.8.0_101/bin/java
to the beginning of the command to point to the 32bit java I have, but no good. same error.
How can I point zdesktop at a 32bit JVM I have downloaded from Oracle?

As an aside WHY do we have to endure this? If we had a 64 bit version (zcs is now all 64 bit) things might work!!

Can you set JAVA_HOME environment variable to point to 32-bit JRE like below and it should work.
e.g. env JAVA_HOME=/opt/java_i586/jre1.8.0_101

32-bit ZD would need 32-bit JRE.

install.pl fails with higher version of openJDK (We have a bug https://bugzilla.zimbra.com/show_bug.cgi?id=106478).

Moreover we are going to support 64-bit version of Zimbra Desktop starting from 7.3. (https://bugzilla.zimbra.com/show_bug.cgi?id=65456).

Let me know if given workaround works for you.

Thanks for such a fast response. Unfortunately it did not work.
Here is the output from the log

Code: Select all

and from the command line:

The JAVA variable is still showing /usr/bin/java which points to my 64bit java
Does that help?

AhHa! I have a workaround
I have made a one line addition to the zdesktop/bin/zdesktop file
below the "Find Java on System" section ie below line 255 I added this:

Code: Select all

JAVA=/opt/java_i586/jre1.8.0_101/bin/java

and bingo it works, AND I can access my accounts!
Thanks for the pointer.
