Here is the scenario to reproduce: - uninstall all JRE's from PC (start clean) - run test html page containing applet (see code below) -> netscape prompts for installation of 1.3.1 as specified via the static versioning MIME type in "<Object>" tag of html (see below) - install JRE 1.3.1 - run test html page containing applet (see code below) -> everything should come up as expected - install JRE 1.4.1 - run test html page containing applet (see code below) -> netscape again prompts for installation of JRE 1.3.1 even though 1.3.1 has already been installed It seems as if the installation of JRE 1.4.1 somehow confused Netscape such that it no longer thought 1.3.1 was installed. This is a problem because our applet will crash if used with anything other than JRE 1.3.1 This can be reproduced with any small applet and has been tried using the "<Applet>" and "<EMBED>" tags as well. Here is the code that specifies static versioning for JRE 1.3.1 and which should bring up the applet. <OBJECT type="application/x-java-applet;jpi-version=1.3.1" archive="TestApplet.jar" WIDTH="100%" HEIGHT="100%"> <PARAM NAME="CODE" VALUE="com.testapplet.TestApplet"> </OBJECT> Thanks for the help. jason Reproducible: Always Steps to Reproduce: 1. uninstall all JRE's from PC (start clean) 2. run test html page containing applet-> netscape prompts for installation of 1.3.1 as specified via the static versioning MIME type in "<Object>" tag of html (see description) 3. install JRE 1.3.1 4. run test html page containing applet-> everything should come up as expected 5. install JRE 1.4.1 6. run test html page containing applet-> netscape again prompts for installation of JRE 1.3.1 even though 1.3.1 has already been installed Actual Results: browser prompts, again, for installation of JRE 1.3.1 even though it has already been installed Expected Results: Detected that JRE 1.3.1 was already installed and proceed to download/open applet
Does it work with TYPE="application/x-java-applet;version=1.3.1" ? Can you copy/paste the output from about:plugins and attach it in a file here? It's possible the 1.3.1 installer didn't recognize the Mozilla plugins folder so the browser reverted to the newest JRE installed on the system. Try setting the environment variable MOZ_PLUGIN_PATH to point the Java 1.3.1 bin directory that has the plugins and restart the browser.

Created attachment 116145 [details] about plugins info for Netscape Here's the about information for Netscape plugins. This is after 1.3.1 and 1.4.1 are both installed. TYPE="application/x-java-applet;version=1.3.1" will work but uses 1.4.1. I need it to work with 1.3.1 only, even if a more recent plugin is installed. In this case it needs to work using "jpi-version".
Peter - any additional thoughts on this?
The 1.3.1 installer did not find Mozilla. Set MOZ_PLUGIN_PATH to point to where the 1.3.1 np Java DDLs are located.
This is not a valid workaround for applets. Are you saying every client in this situation that uses our applet will have to set this path to assure mozilla finds 1.3.1? The whole point of using static versioning is so that you can specifiy which plugin the browser should be using without any intervention from the client, unless it isn't installed, of course. Would you agree then that this is a bug in Mozilla or, perhaps, it is a bug in Sun's 1.3.1 (does not properly install?) I would say the former since IE works properly in this scenario.
Created attachment 116337 [details] about plugins info for Netscape - 2 After setting MOZ_PLUGIN_PATH to point to the plugins directory Mozilla still uses JRE 1.4.1 instead of 1.3.1 as it seems the "About Plugins" would indicate. The file is attached. Please let me know if you have a work-around for this bug as time is pushing us to the point where we may have to nix plans to support Netscape. Thanks. jason
I see a "application/x-java-applet;jpi-version=1.3.1" in your about:plugins and it shows up first, as expected. Do you still get a default plugin or does it just not show up? Set NSPR_LOG_MODULES=Plugin:8 and NSPR_LOG_FILE=c:\log.file to get browser debug plugin log. The Sun installers doesn't always recognize Mozilla but should recognize Netscape. Netscape 6 even shipped with JRE 1.3.1. You often have to copy the DLL's but setting MOZ_PLUGIN_PATH is a shortcut that won't mess up uninstallers. Also see bug 185000, but the current patch looks to be only for UNIX.
Created attachment 116344 [details] plugin log The applet ends up being run in JRE 1.4.1 even though it appears that it should be 1.3.1 as you noted and as seen in the "About Plugins". Attached is the log of the startup of my applet.
Any additional thoughts?
JRE1.3x is old, please reopen if this issue still happens
