Yes, with GENTOO_VM and VMHANDLE of the jvm you want, like |
| 11 |
|
| 12 |
GENTOO_VM="sun-jdk-1.5" |
| 13 |
|
| 14 |
This will make all the wrapper scripts for java, javac, etc. call the |
| 15 |
binaries from selected VM. |
| 16 |
If your program also relies on JAVA_HOME, you can add this after the |
| 17 |
GENTOO_VM line: |
| 18 |
|
| 19 |
JAVA_HOME=$(java-config --jdk-home) |
| 20 |
|
| 21 |
Not sure how you can make it select "any of the 1.4 vm that's installed" |
| 22 |
though... |
| 23 |
|
| 24 |
Also there's some way for packages installed with portage to specify |
| 25 |
what VM they need, but I dont know the details, maybe somebody else... |
