[SOLVED] alternatives - how to use specific group | How to make thinkrswim work with Oracle/Sun and OpenJDK

DBabo · 07-21-2014, 11:14 AM

"alternatives" - is there a way to specify a specific editor to use ?
for example:
i have 2 version of JAVA installed
i want JAVA version 1 be used by program ABC and JAVA version 2 used by all other programs on a machine ...

Update:
I was trying to see how to get thinkorswim to use specific version of java ( SUN/Oracle) using /etc/alternatives. It appears that it's not the right task for /etc/alternatives. For solution to thinkorswim problem see last post in the thread.

You can pass $JAVA_HOME to the script/program.

eg:

Code:

JAVA_HOME=/opt/java/jre1.6/ ./my_program

Did that. Apparently, application requires something else (classes or some other execs ) particular to the java version.

You need to add the path to the classes to your CLASSPATH variable.

right, so should this be handled by alternatives?

You can set it up the same way you did JAVA_HOME in DBabo's comment. I am not sure if that answers your question.

weeelll. here is some internal info.
so i have thinkorswim which requires Oracle Java. on OpenJDK it won't run - that is the fact. I removed all java, installed openjdk - no go. Replaced it with Oracle - works fine.

Next step is i'm trying to "marry" Oracle and OpenJDK in such a way that thinkorswim works and all other apps that require Open ( libreOffice for example) work too.
So i had Oracle 1.7 installed on an empty ( no openjdk) machine and confirmed that thnkorswim work.
Next i installed openJDK 1.7 and confirmed that everything else works but thinkorswim.
Next i set Java_HOME=/usr/bin/java/default:

Code:

echo $JAVA_HOME
/usr/java/default
[xxxx@localhost thinkorswim]$ ls -l /usr/java/default
lrwxrwxrwx 1 root root 16 Jul 15 11:25 /usr/java/default -> /usr/java/latest

which java
/usr/bin/java

[xxxx@localhost thinkorswim]$ java -version
java version "1.7.0_60"
OpenJDK Runtime Environment (fedora-2.5.0.1.fc20-x86_64 u60-b30)
OpenJDK 64-Bit Server VM (build 24.60-b09, mixed mode)

when i run thinkorswim it just sits and "applying updates".

here is the strace on the java call. I removed all non relevent info. As you can see it somehow picks up openjdk which is the problem.

Code:

any ideas?

ohhhh. i'm a stupid monkey, i made a simple task more difficult when it should be :
in the thinkorswim shell launcher _they_ specify :

Code:

# Uncomment the following line to override the JVM search sequence
INSTALL4J_JAVA_HOME_OVERRIDE=/usr/java/default
# Uncomment the following line to add additional VM parameters
# INSTALL4J_ADD_VM_PARAMS=

which is what i did (bold) and now it works fine.
It interesting to note that if this variable is not set ( default) then the script goes over all over options. Such as checking variable passed and eventually arrives to env variable set for the session. YET, the only option that makes the app to wirk is to set OVERRIDE var on top of the script.
