AFAIK, there isn't much difference. The jre is the runtime system which
is intended to be installed on production servers and clients, while the
jdk is for development. The jre is just barebone, while the jdk contains
a lot more stuff, such as source code, and lots of development tools.

you can't convert the .java file to .class file without the jdk "java
develper kit"
but you can run the .class file without jdk

and always the jre must be installed in the clinet pc

Is that to say that the designer of a system based JAVA does NOT need
to installer the jre on the server computer which is for testing?


Namelly,I do NOT need to install jre when I have installed the jdk,yup?

If the server runs a web-container you'd definitely need the jdk,
otherwise it's going to be difficult to get jsp up and running (I guess
they could be pre-compiled, though ...)
