Java download not working in Red Hat 6 64bit

[pkroetsch]

I downloaded the java from sun

I attached a picture of the terminal with error message




any help would be appreciated.

Thanks!

Isn't there a 64-bit version of Java at the download site?

ok you were right...i downloaded the 64 bit and that worked fine...

now I am trying to get the jre working and for some reason it says its already installed but when i try run applications such as my Aventail VPN it says java 1.4 or hight is required.

this is what it shows me on my command line...sorry i am new to linux and i am not sure why it is not working.

I don't know anything about Aventail, but it is clearly not detecting your installation. Is it a web-based app, or a stand-alone GUI, or a command line tool? Does it provide documentation regarding Java requirements?

If web-based, it may be looking for the Java plugin, you can confirm the existence of it by going to aboutlugins in the address bar of firefox.

If command/GUI based, it may be expecting the $JAVA_HOME (or CLASSPATH or some other Java-related variables) to be set. E.g., on my system, I have JAVA_HOME set to /opt/java (b/c that is where I installed Java manually).

Again, check Aventail documentation regarding Java reqmts.
