how to install java for kubuntu

I want to install java on my kubuntu system. It isn't listed under add/remove programs. I find java files with synaptic but I don't know what to install (SE EE ME JRM JDK ... ?). I also looked at Sun's web site and I saw RPMs and self-extracting archives but I don't know how to install these in ubuntu.

1) What do I need to make java run
2) How do I install them in kubuntu

Mick Barry

to see whats available, try:

apt-cache search java

or

apt-cache search sun

Mick Barry

then:

apt-get install <package>

to install it

dibbz

1. install java-package
sudo apt-get install java-package

2. go to http://www.java.com/en/download/manual.jsp and choose "Linux (self-extracting file)", optionally choose the 64bit one, save it, it will be jre-xxxx.bin

3. make a compatible package
fakeroot make-jpkg jre-6u7-linux-i586.bin

4. install package that was just created
sudo dpkg -i sun-j2re1.6_1.6.0+update7_i386.deb

Done!

Not done yet for me. I typed what you said on step 3 and I got the message:

-------------------------------------------

No matching plugin was found.

I cannot continue with step 4 because no package was made. What should I do?

Mick Barry

u shouldn't need to make a package, there should already be one available
did you do a search for what packages are available as I suggested?

I read what you told me to type:

apt-cache search java

but it gives lots of files and I don't know which ones I need. I'm not trying to do anything spectacular. I want to use my 32 bit laptop computer using kubuntu to write a java program with netbeans that makes a nice window where I can enter a golf score ( any input really).

I don't know what files I need to make java run. I am a C++ programmer learning java.

objects: Sun java is not in the ubuntu repository. Maybe you are referring to debian non-free ?

I tested this on a fresh kubuntu install before posting. Can you confirm that you downloaded it OK?

Is this correct [Y/n]: no they don't match There were more differences above what I indicated ( like the ubuntu version ) and I don't know what is important.

Thank you for the help. I didn't know how to work with the multiverse. I am going to update my system to hardy now and get the newer system working ( akayou'll probably hear from me soon on EE ;)
