Hi,
I managed to uninstall all Java versions, and then re-install Java 1.7.
However, when I then try to open Vassal, I get a message telling me that I need to install Java SE 6 to get started.

According to this:
docs.oracle.com/javase/7/docs/we … c-jre.html
the JRE 7 installer doesn’t create proper symlinks for the java binary.
I have no idea why Oracle thinks it’s acceptible for the installer to
behave that way, since it leaves you with exactly this problem. They’re
essentially saying “our installer doesn’t finish doing its job”.
What’s the output now when you run each of the following:
which java
java -version
ls -l /System/Library/Frameworks/JavaVM.framework/Versions

I get
%which java

So, if I understand well, I should install the JDK rather than the JRE ?

This is funny. Apparently MacOS has a placeholder for the java binary.

I’m trying to get a sense of what state your machine is in right now.

Maybe. But don’t do that yet.

Ok. I think this is what you need to do, as root:
cd /System/Library/Frameworks/JavaVM.framework/Versions
rm CurrentJDK
ln -s /Library/Java/JavaVirtualMachines/jdk1.7.0_13.jdk/Contents CurrentJDK
This changes the CurrentJDK link to point to the JDK 7 you just

Vassal still requires Java 6 to start, though.
What do you mean by “VASSAL still requires Java 6”? I don’t understand what you’re seeing.

Guillaume, if you use 1.7 JDK, please make sure you have Java (not javascript) off in your browser. There are security issues.
Guillaume, our jdks are a little different (you are 13 builds ahead of me). Where did you get yours? From Oracle or the Open JDK project?
I have no problem starting Vassal - absolutely no error executing Vassal, however I still have bad graphic output. I execute Vassal from the Applications folder (not through a browser - can you still do that?).
Also, uekelman, I believe I have the same output on the screen as Guillaume in Vassal itself (i.e. no text on the counters). Please see attached image. Note that the Ottomans are on the rampage.
Warmest regards,
Michael
I was wondering Michael, do you know which version of Java Vassal is using ?
I got mine from Oracle : oracle.com/technetwork/java/ … 80260.html
Here is the message I get from Vassal (in French, I am afraid) :

Guillaume
Guillaume, Vassal will use the Java it finds in its class path. That’s why the links are important. A symbolic link points to the current VM. In your case, it will find jdk 7’s libraries now. Do you just execute the Vassal App in the Applications folder?
Interesting… That looks like an Apple message and not a java message.
