Web Tools and the JRE
Listed below are the known limitations in Web Tools, relating to the JRE.
Under some circumstances, users may see a rectangular black area 
corresponding to an applet ICON graphic. 
Workaround: In the Solaris environment, this situation is sometimes 
traceable to a mismatch between the Java Plug-in and the version of Netscape. 
Ensure that the proper JRE has been installed and the correct version of 
Netscape is being executed. 
Older versions of the 1.2.2_02 and the 1.3.1 Java Plug-in for Solaris do not 
support creation of the Fabric Event display. 
Workaround: Ensure the correct JRE version that supplies the correct patch 
version of the Java Plug-in is installed.
The Refresh View button in Fabric View may start blinking 15 seconds after 
the fabric has been refreshed, when actually the fabric has not been changed. 
Workaround: Ensure the correct JRE version that supplies the correct patch 
version of the Java Plug-in is installed.
When using Java Plug-in v1.2.2_008, the jar_cache files can grow too large, 
and may make Web Tools not operate properly. 
Workaround: When using Web Tools with plug-in 1.2.2_008, occasionally 
go into the Temp folder, in Windows 2000 or Windows NT, and delete the 
jar_cache files created by the browser to cache applet information. The 
location of the temp files vary depending on which platform, browser and 
plug-in is used. Discuss with your system administrator where to locate these 
temp files and delete them.
