JRE stands for Java *Runtime* Environment... I won't let you compile anything, and it won't install any such stuff. So - <snip> THIS SYSTEM VM IS NOT SUFFICIENT, REQUIRED BINARIES WERE NOT FOUND </snip> tells it all.
JRE doesn't provide javac, it can't be used as default system VM. Unmerge it and emerge sun-jdk-1.4. You can't use Java 1.5 with stable arch for now.
sorry, I mean "java" not "javac" command.. i suppose that "java" command is included in sun-jre-bin package or I am wrong? I want only *run* java programs, not compile them
Follow http://www.gentoo.org/doc/en/java-old.xml Especially the set-user-vm part (you can't have 1.5 JRE as system VM), I suppose you're not going to run those programs as root but user.
