Setting JAVA path in Appian

Question

Hi, 
 In my Linux server with appian 20.4 installed, 
 the following are the details in the "profile" file in /etc folder -- export JAVA_HOME=/data-01/appian/203/appian/java ---- actually this path does not exist in the server export PATH=$JAVA_HOME/bin:$PATH: 
 But when I run the command 
 echo $JAVA_HOME, I find this -- 
 /usr/lib/jvm/jdk1.8.0_191 
 I tried removing the java folder, in the above path(/usr/lib/jvm/jdk1.8.0_191) and stopping my Appian services, (firstly the Tomcat) but the jsp commands are unrecognisable. As soon as I restored the Java at the above path, everything resumed fine. 
 The JAVA_HOME in the profile file refers to a different path while the actual JAVA location used by my services seems to be different. 
 Can any one guide me to change the JAVA_HOME path? 
 Can I point my Appian services to use the the Java in this path ( /data-01/appian/204/appian/java )? If so where should I set the path for my Appian services to point to this path? 
 
 Thanks, 
 Chetana

Based on what you posted, this should work - no? You also need to reload your shell for the change to take effect. 
 export JAVA_HOME=/data-01/appian/204/appian/java
export PATH=$JAVA_HOME/bin:$PATH: 
 Try running the following after making the update to the file: 
 bash --login
java -version

Looks good to me. 
 I would suggest you log a ticket with Appian support to investigate why Tomcat displayed that message in the logs.
