KB16157: How to change the location of the Java JDK (JAVA_HOME) that Apache Tomcat uses in MicroStrategy Web Universal

To change the location of the Java Development Kit (JDK) that Apache Tomcat uses, one must set the JAVA_HOME variable that Tomcat reads. There are several ways of setting the JAVA_HOME variable, and the following method is one of these ways.
 
Note: In Microsoft Windows, some users would prefer to set the JAVA_HOME variable through the System's Environmental Variables. 
 

• If Tomcat is running under a Unix system, open the catalina.sh file. If Tomcat is running under Windows, open the catalina.bat file.
• At the beginning of the script (and after the comments), place the JAVA_HOME variable and the location of the JDK that Tomcat will use.
  For example:
   
   
  
• Unix: JAVA_HOME=/usr/local/java/jdk1.4.0_13

• Windows: JAVA_HOME=C:\j2sdk1.4.2_14

• Save the changes.
• Start Tomcat. When Tomcat starts it outputs the values of some variables including the JRE_HOME value. Check that the value of the JRE_HOME variable matches the path that was placed in the Catalina file.
