My Java Alternatives

There are 4 programs which provide 'java'.

Selection Command

1 /usr/lib/jvm/jre-1.4.2-gcj/bin/java
2 /usr/lib/jvm/jre-1.6.0-openjdk.x86_64/bin/java
3 /usr/java/jdk1.7.0_09/bin/java
*+ 4 /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java

Installing and pointed Tomcat's java,javac,jar,jre's to jdk1.8.0_51, jdk1.8.0_91 didn't help

0.13 needs java8 + tomcat8

[dethrophes]

I had this issue and I found a bug in my install.

1. the tomcat8 service script doesn'T support the jre install paths.
   I fiexd this by editing the script to add the differetn folder paths.

changed

        for jvmdir in /usr/lib/jvm/java-${java_version}-openjdk-* \
                      /usr/lib/jvm/jdk-${java_version}-oracle-* \
                      /usr/lib/jvm/jre-${java_version}-oracle-*
 

to

        for jvmdir in /usr/lib/jvm/java-${java_version}-openjdk-* \
                      /usr/lib/jvm/jdk-${java_version}-oracle-* \
                      /usr/lib/jvm/java-${java_version}-oracle* \
                      /usr/lib/jvm/jre-${java_version}-oracle-*

2. edited the catalina.sh script to make it compatible with jre8
   https://bugs.launchpad.net/ubuntu/+source/tomcat8/+bug/1586054
   bascally remoce the args -Djava.endorsed.dirs from the file /usr/share/tomcat8/bin/catalina.sh
