Table D-3 HotJava Views Error Messages and Suggested Actions

Message or Problem 

Action 

JavaOS 1.1 boots OK, but upon login, the heap viewer applet displays instead of Views. 

The alternate main parameters are not getting passed to JavaOS. Make sure you have specified the correct URL in the -i option in /var/dhcp/dhcptab. Use a web browser to verify the URL.

Make sure the javaos.mainProgram, javaos.mainZip and javaos.mainHomeprop parameters are correctly specified in the javaosopt.txt file. Use the -i URL indirection.

Make sure you have sent a SIGHUP to in.dhcpd if you have changed the /var/dhcp/dhcptab file.

JavaOS 1.1 boots OK, but upon login, a blue screen displays instead of Views. 

JavaOS has received the alternate main parameters, but they are incorrect. Make sure javaos.mainProgram and javaos.mainZip are specified correctly in the javaosopt.txt file. Verify the URLs are correct by using a web browser.

class not found/defined error

This error is common if you are using the JavaServer(TM) server. Servers may fail to handle HTTP requests. If this happens when Views is trying to load a class file, you get a class not found/defined error.

Try using the Apache or Netscape server to correct this problem.  

Tables do not parse well in WebView. 

The .jdt/props/selector.props files may contain invalid entries for class names that handle HTML tags.

Check your selector.props file for entries that specify classes that start with sun.hotjava. If you find such entries, move your.jdt/props/selector.props file aside (don't forget to reset your proxies).

After modifying Appointment Reminder properties within the Properties dialog, the appointment reminder types (Post Notice and /or Ring Bell) do not match the property value settings. 

Restart Selector for the new property setting to take effect. 

Several (or many) reminders are posted for a single appointment. 

Chances are your calendar file is in an older format, and/or your workstation has a different time than your calendar server. Update your calendar file and sync your workstation clock with the server's clock. 

No reminders are displayed for appointments inserted through Month view. 

After inserting appointments in Month view, perform an action that reloads your calendar, such as changing the month you're viewing or switching to Day view or Week view. 

Closing the Mail Login dialog in Calendarview can cause HotJava Views to lock up. 

Don't close the Mail Login dialog using the window menu. Use the Login and Cancel buttons to close the dialog. 

HotJava Views complains about not being able to mount my home directory. 

JavaOS mounts your home directory when you log in. It gets the location of your home directory from the passwd and auto.home NIS maps. Make sure these maps are correct and that your home directory is properly exported so the NC can mount it.

You can run snoop(1M) and watch for the MOUNT request that happens after you log into JavaOS.

snoop(1M) doesn't show all the packets from the NC.

You may be on a switched network. In this case, packets from the NC may not be visible to the system on which you are running snoop.

The best way to make sure you see all packets is to plug the NC and your Solaris system into a mini-hub and run snoop etherid for javastation.
