Name: sh38129 Date: 01/22/99


We have a time entry applet that uses a grid layout for each day and project. If the user enters hours for a particular day, but then leaves the page (before saving) by clicking the back,home, etc buttons, we present the user with a warning that they have unsaved data. The warning is a simple frame that allows the user to click on "Save" or "Don't Save" buttons. If "Save" is clicked, a request (with the updated data) is sent to the server for insertion/update in the database. This scenario is captured by checking for changed data in the applet's stop() method.

Even though the browser exits the applet page, this frame is displayed quickly and works just fine under Netscape 3. However, under IE 4.0, the browser goes comatose. It goes into "Not Responding" mode for about 90-120 seconds and partially paints the frame. After this coma time period, the browser revives, finishes painting the frame, loads the page per the user request, and if the user clicks "Save", the data is saved in the database. Everything works, but the user has to wait 2 minutes for the browser to come back to life.

I loaded the jdk 1.2 production release to see if that would take care of the problem, however, using the 1.2 plugin causes Dr. Watson to appear when I load the applet. I get this if the applet source has been compiled under the jdk 1.1.5 or 1.2 compiler. The console displays messages regarding caching errors, which I have not seen before, so I'm assuming this is causing the crash.

However, if I load the 1.2 plugin, but tell the 1.2 Control Panel Applet to use the 1.1.6 JRE, IE 4.0 performs just fine. No hangs, etc.

I haven't tried Netscape 4, but as I said before, the plugin works fine under Netscape 3. Based on this behavior, I'm guessing that the actual plugin for IE has the bug. I'm assuming that the ActiveX control that IE is utilizing as the plugin is not communicating properly with the browser, while the Netscape plugin(which is really a plugin) doesn't have the problem. This assumption is also confirmed since the 1.2 IE plugin works ok with the JRE 1.1.6.

Now, if I could just get the JRE 1.2 working properly, I'd be set, but for now, I have to have both JRE 1.1.6 and JRE 1.2 loaded so the 1.2 plugin can access the 1.1.6 JRE. When I load the applet under JRE 1.2, the console spews out several CacheHandler errors and IE dies with a Dr. Watson.

I have been experimenting with the 1.1 plugin and have gotten the "wait" or "Not Responding" time period down to about 15 seconds (instead of 2 minutes). In the stop() method, I create the "Save" frame and then put the thread into a wait state for 5 secords so the browser doesn't call destroy()immediately. This seems to give the applet some more time to present the frame to the user, but it still delays for 15 seconds. Weird...
