JDK1.6.0_01 contains jre, do I still need to jre separately ? if yes, why ?

JDK contains bin folder and it also contains JRE folder. Now inside JRE, there is a bi folder. So which bin folder I set my path to ?

In Head First Java book, it is mentioned to download J2SE documentation API and on, there is Java SE 6 Documentation. Is this the one mentioned in book and a developer is supposed to download ?if not then which Documentation API shall I download ?

My jdk download is in c directory , so command to set path will be
c:>set path=c:\jdk1.6.0_01\jre\bin is this right ? Do I point to jre bin or just jdk bin ?)
now if I want to make this path permanent, at command prompt I type
c:>%path%;set path=c:\jdk1.6.0_01\jre\bin is this right,pls correct if not

Thanks for co-operation

Welcome to JavaRanch!

The JDK includes the JRE, and you do not need a "separate" JRE.

Assuming that you are running Windows, see Sun's JDK installation instructions. Step 4 describes setting the PATH variable for the JDK bin directory.

Yes, the "Java SE 6 Documentation" sounds correct. See Sun's documentation installation instructions.

Let us know how this works for you.

Hi jignesh soni:

JDK contains bin folder and it also contains JRE folder. Now inside JRE, there is a bin folder. So which bin folder I set my path to ?....

You have to set your path variable to point to BIN folder inside JDK HOME DIRECTORY in your case its c:\jdk1.6.0_01\
You have to use
c:\>set path=c:\jdk1.6.0_01\bin;
