[CentOS] Java 1.5

Hello,

i'm trying to install jboss where it asks me for java 1.5
i have both 1.4 and 1.6 installed
with JAVA_HOME pointing to 1.6

i downloaded jdk-1_5_0_17-linux-i586.bin  and executed it..
though nothing changed..
when i execute : alternatives --config java

i can only see 1.4 and 1.6

any advice?
