Re: How to set the default Java version

There are a couple of different things you can do depending on who you want
to effect.

1). To affect just your compile, and only adjusting the javac command:
      javac -J-Djava.version=1.3 ...
      NOTE: You do not qualify the path name to javac - specifying the java
version to use via -J-Djava.version=1.3 picks up things correctly for you.

2). To affect just you compiles, without adjusting javac command each time:
       Create file SytemDefault.properties in directory
/home/yourUserProfile (or whatever directory is specified for your
user.home) and add the line "java.version=1.3"   (without the double
quotes).
       E.g.:
       mkdir '/home/yourUserProfile'     where yourUserProfile is your
As/400 user profile name
       edtf '/home/yourUserProfile/SystemDefault.properties
       java.version=1.3
       PF3 twice to save and exit

3). To effect everyone on the system, add (or change) the line
"java.version=1.3"   (without the double quotes) to file
/QIBM/UserData/Java400/SystemDefault.properties   (create the file using
editf if it does not exist).

Can anyone advise how I can set the Default Java version on the AS400.
We have three versions: 1.1.8, 1.2 and 1.3 and it looks as if the default
version is 1.1.8.
I am compiling my programs under 1.3, using the command
/QIBM/ProdData/Java400/jdk13/bin/javac   ServletSample.java
When I execute a java program in QShell using the java command, I' getting
run-time errors
that would not occur under jdk 1.3.
When I check the version with the QShell command:  java -version, I see
1.1.8.
Thanks
