Answer 1

• Install complete, Compatible JDK from Oracle (SUN) or IBM
• Set your JAVA_HOME environment variable to the root directory of the compatible JDK

$ JAVA_HOME=/usr/java/jdk1.6.0_01

$ export JAVA_HOME

• Put the compatibale JDK's bin directory on the front of your PATH environment variable.

$ PATH=$JAVA_HOME/bin:$PATH

$ export PATH

• Find the java executable of the incompatible JDK, usually /usr/bin/java and move it out of the way, like this:

$ cd /usr/java

$ mv java java.moved

• Then, check to make sure your java executable points to the JDK you have installed:

$ which java

/usr/java/jdk1.6.0_01/bin/java

Answer 2

I had the same problem and I got it resolved by specifying proper JRE_HOME. Basically I made JRE_HOME same as JAVA_HOME.

Answer 3

include following property in catalina.sh

-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
