Answer 1

You should do sudo ./jdk-1_5_0_22-linux-i586.bin, since you don't have write permission in that directory. However, root does.

Answer 2

Execute your bin with super user permission sudo. Also if you have newest version of JDK (I suppose you do) you can set compliance level of sources to 1.5

Answer 3

You need permissions for it. You have two options, either switch into a super user mode, using:

#su

Though this method is not encouraged. The second and the most common and appropriate method is to use sudo command,as:

#sudo ./jdk-1_5_0_22-linux-i586.bin
