Netscape browser give Java plugin detect JRE collision

hi
when i run my application on Netscape v8.0 i got a problem metioned in subject line. please help me for this.
thanx in advance

first uninstall all the previous JRE version.
Open Jav plug-in from control panel and select the java tab,
Select only one JRE version into this tab.
restart ur browser, perhaps u does not get this problem in future.

Problem installing java plugin from jre 1.4.0 on netscape 4.79

We tried to install the newest java plugin on netscape
4.79 on our Solaris 2.8 machine. Followed the instruction, we first downloaded j2re-1_4_0-solsparc.sh, ran the script to create a
directory called j2re1.4.0, then set the NPX_PLUGIN_PATH environment variable to the directory
containing the javaplugin.so file. When we tried to
start netscape, we got the following error message:
INTERNAL ERROR on Browser End: Could not load the function CreateOJIFactory
System error?:: No such file or directory
What is the problem? Any fix?
Thanks

Hi,
From your description, it seems you've read http://java.sun.com/j2se/1.4/install-solaris.html#plugin . This also states that the supported Netscape builds go up to 4.77 before moving on to Netscape 6.x. And in this case it appears that this isn't just because the documentation hasn't kept up with recent activity from Netscape. Netscape 4.79 appears to treat the plugin differently, and/or still expect the old Activator code to be in place to use it.
I'm using the 1.4.0 JRE with no trouble at all with Netscape 7.0PR1. If anything this - and the Mozilla 1.0RC2 build that it's based on - are far more stable than any of the NS4.x releases. The only reason I can see for staying with 4.x is that it'd little more lax with the HTML it reads, and displays some bad pages that NS6/7 refuses to display.
Recent Solaris releases come with Netscape 6 as well, and it's easily downloadable. I'm sorry I can't be more help than this.

Java Plugin Detection using VBScript on Internet Explorer

Hi,
I need a way to detect when the plugin version is above a certain version number (such as 1.4.1 or higher) so that I can give the user some extra info as to what is happening when the plugin is downloading automatically on Internet Explorer. Something like :-
"Please wait for Java plugin to download"
At present there is a long delay when the user may not know what is happening as no info is relayed back to user.
I know that the presence of the plugin can be detected using vbscript but not with JavaScript but how do i determine that the user has 1.4.1 or higher. I use the following code:
<script language="vbscript">
If IsObject(CreateObject("JavaPlugin"))=True Then
document.writeln("some info to user")
End If
</script>
This tells me if a JavaPlugin is installed but not what version so we still dont know whether the applet will run or the plugin will download.
I have also tried:
<script language="vbscript">
If IsObject(CreateObject("JavaPlugin.141"))=True Then
document.writeln("some info to user")
End If
</script>
this works but what if the user already has a version greater than 1.4.1 this is not detected and a nonsense message saying that the Java plugin is downloading is displayed.
Any ideas?

Here's JavaPlugin detection for netscape and ie using JavaScript . . .
Throw this in a .js file and source it at the start of you html.
function detectPlugin() {
     var thePlugins = detectPlugin.arguments;     // allow for multiple checks in a single pass
     var pluginFound = false;               // consider pluginFound to be false until proven true
     // if plugins array is there and not fake
     if (navigator.plugins && navigator.plugins.length > 0) {
var pluginsArrayLength = navigator.plugins.length;
          // for each plugin loop through all desired names and check each against the current plugin name
for (pluginsArrayCounter=0; pluginsArrayCounter < pluginsArrayLength; pluginsArrayCounter++ ) {
var numFound = 0;
for(namesCounter=0; namesCounter < thePlugins.length; namesCounter++) {
                    // if desired plugin name is found in either plugin name or description     the pluginFound
if( (navigator.plugins[pluginsArrayCounter].name.indexOf(thePlugins[namesCounter]) >= 0) || (navigator.plugins[pluginsArrayCounter].description.indexOf(thePlugins[namesCounter]) >= 0) ) {
numFound++;
               // now that we have checked all the required names against this one plugin,
               // if the number we found matches the total number provided then we were successful
if(numFound == thePlugins.length) {
pluginFound = true;
                    // if we've found the plugin, we can stop looking through at the rest of the plugins
break;

Forms Web application is not working on FireFox Browser-with java plugin

Hi All,
We are running custom build forms application using forms 10g and application server 10 g Rel 2. We are using Java Plug-in 1.5.0_06. The application is working fine before recent update from firefox .Now it's not working and keep on asking additional plug in required and taking to java.sun.com for installing the plug in. Even after installing when we access the application it will do the same thing. I tried uninstalling the firefox with the older version and with diffrent java plugin versions.. but the problem still there.. any help will be mush appriciated...
Thanks...

Disable java plugin in browser for obiee 10.1.3.4.0 analytics,bi publisher?

Hi,
Company using obiee 10.1.3.4.0, installed on aix machine, using IBM websphere server for the presentation layer.
Due to the recent java security alert, my company like to disable the browser java plugin.
Question is does obiee needs the browser to have the java plugin?
Can obiee analytics and bi publisher work properly through the browser without java plugin? Hope some experts here can provide me some answers. Thanks in advance!

Thanks very much to responding to my question.
I tried by disabling the Java Plugin in my IE browser and open a few chart reports with no problem.
Have you actually experience problem when you do that? Like to know when will it actually have problem.

JRE Detected---Version Collision problem!!--plz help..it's urgent

Hello ,
I am working on developing a upload component in applets that would be used to
Let the user browse thru his/her local file system, select it and then upload that file
to a Specific location on the server, during this file transfer operation it also
Shows the bytes remaining and a progress bar with percentage.
I have developed it already and my purpose is to make it available as a cross-
Platform independent component that can simply be merged/used with just about
any application developed in any language/or on any platform and so I developed
it in java using applets, bcauz it has to run and be accessible via a browser.
Now, the component is working fine but there�s a problem to which I have not
Found a complete and stable solution.
The problem is with the JRE(Java Runtime Environment), that if the html page that
Contains my applet does find a JRE already installed on someone�s browser but
With a different version to that of which I have used for example(1.4.2_07-b05) it
Gives an error saying �jre detected-version collision� and I understand fully by
Looking up on net as to what this error means, but how do I remove this problem
i.e. I simply want that (since I am already using the OBJECT tag in my html file)
when my html page containing loads up in any one�s browser then even if that
browser doesn�t contains a JRE in it, it should(my applet)should run, as I guess
my browser only had a default MSJVM earlier and had no JRE for instance, still
any site that I opened on net which contained applets , never gave me any such
kind of error.?
One temporary solution that I did, (although it�s not what I would like to do as it is
not user friendly at all) is that in my OBJECT tag I had used a codebase attribute
which contains the path of my jre�s exe file like this:
I am giving here the complete code for my html file:
<html>
<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" name="Helper" width="900" height="200"
codebase="http://10.11.13.63:8090/j2re-1_4_2_07-windows-i586-p.exe">
<PARAM name="java_code" value="FileChooserDemo.class">
<PARAM name="java_archive" value="filechooser.jar">
<PARAM name="type" value="application/x-java-applet;version=1.4">
<PARAM name="progressbar" value="true">
<PARAM name="boxmessage" value="Please...wait..while..the..applet..starts..up">
<COMMENT>
<NOEMBED>
</NOEMBED>
</COMMENT>
</OBJECT>
</html>
further I also have to take care that if the above problem occurs i.e.(�JRE detected-version collsion�) then I got to tell the user to first go into his/her control panel and then
remove the JRE�s exe file from add/remove programs and then come back to his/her browser to get the JRE�s exe file downloaded automatically from the location of intranet
(my web server path) and run itself and install it on his/her browser bcauz of the tag that
I used above.
But all this is not at all a user friendly solution and I would not want any user to go thru the hassle of all this.
Can there be any way to let my applet run on any browser without the JRE problem ,
Plz suggest as I have now fully developed my applet upload component after a month�s
hard work , but is not able to now finally integrate it with our email server application that we have in our office, just bcauz of this problem..
Thanks in anticipation
Regards

I don't know what version collition means but what jdk version you used to compile your
applet?
clsid:8AD9C840-044E-11D1-B3E9-00805F499D93 is dynamic versioning classid and
allowes IE to run your applet with any installed jre without trying to install a newer one.
Problem here is when you compiled with 1.5 and try to run it with an older version there
might be some problems.
Try to compile it with -source and -target option so your applet is compatible with 1.3
http://java.sun.com/products/plugin/versions.html
Another thing is that your platform independent file uploader will only run in active x
enabled browsers like Microsoft Internet Explorer and not with mozilla(see link above) .

ANSWER: HOW TO DETECT Java Plugin from JavaScript

I created a new topic because the questions about
how to detect Java Plugin in browsers are scattered
thoughout this forum.
Basically you need to employ two approaches for IE and NS.
In IE you need to try to instantiate a small applet
(not your production applet) in order to see if browser
can do it. if the browser can do it, you can make a
call applet from JavaScript in order to find version of
JRE (as well as a host of other things).
In NS you can write a simple JavaScript which will
interrogate the browser for all plugins installed. Then
ypu can make a desicion whether to pass execution to
the next(or generated) page which hosts your applet,
or ask the user to download/install a plugin.
I ecourage everybody to host a plugin on your site
rather leave default link to it which is generated by
html converter.
In order to run sample,
Prerequisites:
Java Plugin 1.3.
If you have a different version of plugin,
substitute hardcoded plugin version in JavaScript for
value that you have.
1. compile java file
2. put class file in the same directory with html file
3. load html file into the browser.
4. press "Check Java Plugin.." button
5. see it work
6. examine code
7. uninstall plugin
8. repeat steps 1 - 4
9. see it work
10. install plugin.
Sample code follows:

I'm using Windows XP Home with Netscape 7.1, and the Java plugin won't work.
Java Plug-in 1.4.2_05 for Netscape Navigator (DLL Helper) is listed 7 times in Help>About:Plugins;
The Java Plugin works in Internet Explorer (I use the Test Java Virtual Machine to determine this). With Netscape, I just get the "Click here to get the plugin" window, and believe me, I've clicked here many times, and gone through the installation process, and it still doesn't work. I've uninstalled Java, rebooted, and installed it with the browsers closed, and it still doesn't work. Everything else in Netscape seems to be working properly.
Under Edit>Preferences>Advanced in Netscape I have "Enable Java" checked.
I posted this problem in the Windows-BBS Netscape and Mozilla forum, http://www.windowsbbs.com/showthread.php?t=33994, and tried everything suggested there, but it still didn't work.
Anybody have any suggestions?

I was facing a similar problem. I think the problem is with different versions of JRE. For example, I was trying to associate with Netscape the JRE version of 1.4.2_01 without any success. But on associating jdk version 1.4.2_05, it started working fine.

Is it possible to provide autoinstallation of only java plugin not full jre

Hi all
I m using the HTML convertor to convert the html pages to deploy the applet in a mixed browser enviornment and also to autodownload the java plugin. It takes quite sometime for the autoinstall the plugin. Is it possible to provide the autodownload only te java plugin and not the full jre.
Thanks in advance for the reply

No, the "plug-in" is just an ActiveX/BHO/Browser Extension/etc object (they've all been used) in the browser. The JRE does the work and is required.

Java plugin hangs when communicating to browser scripts (Using JSObject)

I saw several questions in the forum regarding the Java plug-in 1.3.1, however I would like to post this as separately since I want your attention to this, ASAP.
The problem is this, when I run Java Swing Applet using IE 5.0 with the Java plug-in 1.3.1 communication from Applet to browser hangs. (This is by using the JSObject shipped with the IE5). I communicate with the browser using Java Script functions calling from the applet to the browser. For example
win.call("Func_to_call",Value); But the same code is working when compiled and run under Java plug-in and JRE for version 1.3.0.
Please help. I think the problem may be with the JSObject that I use (May be incompatible with the JRE or plug-in of 1.3.1), can you please suggest a solution or give me a URL to find the latest JSObject for the plug-in 1.3.1.
Thanks in advance
Nuuwi

oops... forgot to say what is this 'win'
'win' is the windows object taken as
win = JSObject.getWindow(this); [\code]
thanx

Applet AccessControlExceptions using Netscape and Java plugin

I get the following AccessControlException when running a simple applet that tries to connect to an RMI object when using Netscape Communicator 4.5 with the Java plugin supplied with JDK1.3
java.security.AccessControlException: access denied (java.net.SocketPermission 10.195.57.34:1489 connect,resolve)The HTML page contains the following code:
<embed type=application/x-java-applet;version=1.3
code=test.AppletTest archive=AppletTest.jar width=800 height=600>
</embed>I have modified the default policy file C:\jdk1.3\jre\lib\security\java.policy with the following:
grant {permission java.security.AllPermission;};
With the above change the applet works when using appletviewer but if I remove this change I get the same AccessControlException as I do with Netscape.
This suggests that the Java plugin is not using the default policy file. What am I doing wrong / how can I fix it?
Thanks,
Neil

Alon,
Thanks for the information. The fact that appletviewer and Netscape may be using different security files because of having different java.homes certainly explains the differences I'm experiencing between the two.
I've now modified C:\Program Files\JavaSoft\JRE\1.3\lib\security\java.policy which now reads as follows:
grant codeBase "file:${java.home}/lib/ext/*" {
permission java.security.AllPermission;
grant {
permission java.security.AllPermission;
};but I've not changed C:\Program Files\JavaSoft\JRE\1.3\lib\security\java.security. Unfortunately this still doen't work with Netscape. In your reply you mention changing java.security files - am I making the wrong changes?

How to uninstall java plugin without removing JRE completely

how to uninstall java plugin without removing JRE completely.
Hope someonce can help, all the documentation ive seen till now shows how to uninstall the Java plugin by completely removing the JRE.
Also if you install JRE 1.4.1_01 and do not choose to install the browser plugin on the browers prompted ... does it not install the plugin?

In IE
Tools -> Internet Options -> Settings -> View Objects
Delete the ActiveX control for the Java Plugin
This removes the ActiveX control (plug-in) from the browser but doesn't delete the JRE.

Netscape browser give Java plugin detect JRE collision
