freemind wont run despite OpenJDK JRE installed

Question

I install freemind from USC Ubuntu 12.04, but it failed to run with the following error:

"

[warning] /usr/bin/freemind: No java runtime was found
[error] /usr/bin/freemind:

Unable to find an appropriate java runtime. See java_wrappers(7) for help"

OpenJDK Java 6 runtime was installed.

Answer 1

Run update-alternatives --config java and make sure you configure it correctly.

Run java -version in a terminal and see the output.

From freemind web: http://freemind.sourceforge.net/wiki/index.php/Download

Freemind may not work with OpenJDK. I would recommend installing Sun/Oracle JRE/JDK.

A simple way of installing it on Ubuntu (build .deb packages from OTN binaries and set up a local repository, use apt-get to install;-) Check it out here: https://github.com/flexiondotorg/oab-java6

Answer 2

The above did not work for me on Ubuntu 12.04/GNOME Shell with FreeMind 0.9.0 installed from the Ubuntu repository, this set up:

freemind
[warning] /usr/bin/freemind: No java runtime was found
[error] /usr/bin/freemind: Unable to find an appropriate java runtime. See java_wrappers(7) for help

java -version
java version "1.7.0_10"
Java(TM) SE Runtime Environment (build 1.7.0_10-b18)
Java HotSpot(TM) 64-Bit Server VM (build 23.6-b04, mixed mode)

sudo update-alternatives --config java
There are 2 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                     Priority   Status

  2            /usr/lib/jvm/java-7-oracle/jre/bin/java   12        manual mode

Troubleshoot:
"/usr/lib/java-wrappers/jvm-list.sh" has the below setting, which is correct path.

#va-wrappers(7) default runtime
__jvm_default="/usr/lib/jvm/default-java/"

The 2 error are coming from /usr/lib/java-wrappers/java-wrappers.sh, which doesn't seem to be loading the below from within it's file.

# Import the list of JVMs
. /usr/lib/java-wrappers/jvm-list.sh

I changed it to,

./usr/lib/java-wrappers/jvm-list.sh

but it did not work.

Solution:

This is what worked after trial and error by adding the below in the /usr/lib/java-wrappers/java-wrappers.sh file, under where it is trying to find,

if [ -z "$JAVA_HOME" ]; then, at line 90 in vi for me.

#DIRS=""
        # Added 2013-01-12 not being found from jvm-list
        DIRS="$__jvm_default"
        #DIRS="/usr/lib/jvm/default-java"

I commented out DIRS="" variable and changed it to

DIRS="$__jvm_default"

or

DIRS="/usr/lib/jvm/default-java"

Both of them worked.
