Installation Basics

When doing an FTP download, the popup will ask the usual Open/Save to Disk/Exe options, since our files end with a .exe extension. Do NOT try to execute it. You should save to disk because the pieces are not individually installable.

Renaming the files to shorter filenames can really help.

Make sure the files are all in the same directory before typing the comand line to copy them into one big file. (called 'concatenating' the files)

On Win95 or 98 systems, the command line buffer is only 128 characters long, NOT enough for the entire command needed. Either use really short names, or use a batch file.

To create a batch file

• use "Notepad" on your system
• cut'n'paste the "copy" command block on our Windows installation notes into the notepad editor
• This is very important! remove all the "new line" characters (carriage returns) so that you have one very long line
• type the name of the batch file at the DOS prompt
• you should see the names of the pieces being displayed

Class Path errors

'Setting the Classpath' is covered in the Tools documentation for
• J2SE v1.3

Platform specific help for common compiling errors is available in the Get Started index of the Java Tutorial. The tutorial provides a great introduction to object oriented programming with the Java platform.

Corrupt Cab

For the multi-part JDK or Java 2 SDK download you need to first download all the files. Each file needs to be the exact size as indicated on the download page.

When the header information for Windows files isn't as expected, the system gives a "corrupt cabinet file" error. Because of the multi-part download, the header is only in the 1st piece, not in any other pieces. Therefore, the OS will give errors about:

• the first, because the size and checksum won't match the header info
• the others, because they lack header info

After all the files have been downloaded, they need to be linked together (concatenation instructions available by version).

If you have downloaded the binary as one large piece and are getting this error message, please try the following:

• delete previous version of JDK or SDK from PATH
• use Remove/Add from the control panel to make sure that the previous version has, in fact, been removed. You may need to edit the registry, as well
• reboot your machine
• reinstall

Checking the file size

Some Windows system will report the downloaded file size in KB instead of actual file size in bytes. For better verification, you can use the "dir" command in the directory where the file is located, or by using the "Properties" option.

Decompression error

If the download file size is correct, the cause of the problem may be the extractor that you are using. We suggest:
• Make sure file size is correct.
• Make sure you have the latest extractor
  (such as: Winzip or PKZip)
• Make sure that you have sufficient disk space where tmp files are stored.
