Writing Servlets

JSWDK 1.0.1 Note

Win95/98 users may experience some problems with running out of environment space when running startserver.bat to start the Java Web Server. Sun's documentation recommends increasing the environment size on the MS-DOS window to 2816.

Unfortunately this advice does not always work. If your environment settings are only moderately filled, then increasing the space all the way up to 4096 (the maximum setting) may work.

However, some of you wrote in to say that this still did not help. So we investigated ways to mitigate this issue.

It turns out that the reason for this problem is that the way Sun wrote the startserver.bat file uses quite a few temporary environment variables.

The way this batch file uses temporary environment variables is quite wasteful. If you are always using the environment space for other programs, you may run out of environment space regardless of whether you increase it to the maximum allowable. For those of you experiencing this problem, I rewrote the startserver.bat file to be more efficient on memory. You can use this new batch file in place of Sun's own startserver.bat file.
