I tried to download RedHat RPM shell script ,but it failed.

The best answer: Yes, you can use the tar.gz shellscript, no problem. It's maybe even easier than the rpm.
After making the package runnable (the same with the RPM, if that was your problem: e.g. chmod 750 j2se-{version}.tar.gz.sh) and run it
(./j2se-{version}.tar.gz,sh), where you will be asked to agree to the SUN Java licence, the shell-script will create a .tar.gz in the directory. Then simply uncompress it (gunzip filename.tar.gz) and unpack it (tar xf filename.tar, you can also make uncompression and unpacking in one way, see man tar). You can unpack it directly to the right dir, or somewhere else, or in the current dir and then move it where you want it. Adding the PATH, if preffered, and it should work.
You can also take a look to

for special Linux JDK's. IBM is also providing JDK's (or j2se's as now called) for Linux, which are often benchmarked to be the fastest on Linux (e.g. the ibm-jdk-1.1.8 was mentioned the prefered one in the Readme in apache jserv and other Java - Tools).
Why does the download of the RPM failed ? Linux also has Download Manager (e.g. caitoo), or you give the URL to the JDK to wget (wget -c can continue the DL later on, if it breaks). It is known that Netscape sometimes corrupt Files, even on Win.
