Java6 Problems

Followed masterG tutorial and all seems well i put the deb line "deb hxxp://ftp.debian.org/debian unstable non-free" in sources.list and then apt-getupdate. Then when i get to the apt-get install sun-java6-jre and run the command i get

"apt-get install sun-java6-jre"

Reading package lists... Done
Building dependency tree
Reading state information... Done
Package sun-java6-jre is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'sun-java6-jre' has no installation candidate

I have tried different packages in sources.list but still having problems trying to get this installed.

Anyone know where i could be going wrong??

Finally managed to install sunjava6 from gui but now when i run the command ./cardproxy.sh start it gives me

Starting CardServProxy: [ FAILED ]
Startup failed: Unsupported java vm 'OpenJDK Client VM', only the original sun v
m has been tested with csp.

This is a true test of patience lol. Someone please rescue me before i spend another 8 hours trying to sort this.

Thanks glenviewjf. I have it installed now after days of trying.
The only problem is when i go to start ./cardproxy.sh i get this error:
"Startup failed: Unsupported java vm 'OpenJDK Client VM', only the original sun vm has been tested with csp"

Any suggestions. Im getting there slowly but surely.

Yes sorted it finally here's the commands that fixed it

"apt-get install sun-java6-bin sun-java6-jre sun-java6-jdk sun-java6-plugin"
"update-java-alternatives -s java-6-sun"

For anyone that ever has this problem.
