Java plug-in support on PPAPI

Any road map on supporting java plug-in using PPAPI architecture of google ? Basically what happens if chrome stops supporting NPAPI; how do we get java running.

That's a great question. Chrome is blocking the jre plugin totally in Sep 2015.

Java Plug-in / JSObject support with IE and Firefox

Hi there,
Basicaly, the idea behind is to write objects in Java to replace or extend functionnalities of a web page (like XMLHttpRequest object). Those objects should support event handler writen in Javascript.
My first idea was to create JavaBeans and instantiate them through OBJECT tags in HTML (not as ActiveX objects). I don't find a way to instatiate a Javabean which was not also an applet.
Does someone knows how to ?
Anyway, the OBJECT tag may not work with Netscape. So, I went to use the APPLET tag with the Sun Java Plug-in.
I've made some tests with IE and Firefox and there is at least two differences between them (both use the Sun Java Plug-in) :
1/ Firefox / JSObject
When you pass a Javascript object to a Java method, it seems that you
cannot use methods like 'getMember', 'call', etc on this object.
(invocation of the method works but returns null)
But, if you access the same object form inside Java starting by
JSObject.getWindows(...) and so on, it works fine.
IE works in all cases.
Example, with the Java applet and HTML below :
. Java applet :
| package JavaJS;
|
| import netscape.javascript.*;
|
| public class FirefoxApplet
|        extends java.applet.Applet {
|   netscape.javascript.JSObject win = null;
|
|   public void init() {
|     win = netscape.javascript.JSObject.getWindow(this);
|   }
|
|   public Object getJSObjectMember( netscape.javascript.JSObject jso, String member ) {
|     return jso.getMember(member);
|   }
|
|   public netscape.javascript.JSObject getJSObjectFromPath( String jsoPath ) {
|     String [] jsoNames = jsoPath.split("\\.");
|     netscape.javascript.JSObject jso = win;
|
|     for( int i = 0; ( i < jsoNames.length ); i++ )
|       jso = (netscape.javascript.JSObject)jso.getMember(jsoNames);
|
| return jso;
| }
|
| public Object getJSObjectPathMember( String jsoPath, String member ) {
| return getJSObjectMember(getJSObjectFromPath(jsoPath),member);
| }
| }

2/ Internet Explorer / JSObject
As we have seen in the previous example, passing Javascript object to
an applet method works. Here, the problem comes when a Javascript object
is pass to a method that's not an applet's method.
If within the applet, you instantiate a new Java object and then
call from Javascript a method on this object with a Javascript object as
parameter then an Exception is raised when invoking that method.
Firefox works fine here.
Example, with the Java applet and HTML page below :
. Java applet :
| package JavaJS;
|
| public class IEApplet extends java.applet.Applet {
|
|   public void init() {
|   }
|
|   public Object echo( Object object ) {
|     return object;
|   }
|
|   public Object newEcho() {
|     return new Echo();
|   }
| }
. Java Echo class
| package JavaJS;
|
| public class Echo {
|
|   public Echo() {
|   }
|
|   public Object echo(Object object) {
|     return object;
|   }
| }

parameter.
Anyway, my questions are : regarding points 1/ and 2/ are these bugs with the Sun Java Plug-in ? or someone could explain these behaviors ?
Thanks for your reading.

After uninstalling and installing several times, Java plug-in is still undetected. Support suggested I open up the control panel and click update but there isn't such an option. The advance tab, there aren't any options to enable or disable plug-ins.

If you're running Java 7, then in System Preferences > Java > Java Control Panel in the Security tab there is a check box to enable Java in your browser. To check for update go to the Update tab.

Minecraft says that I need a new Java plug in but I can't find one from Support. I thought Mountain Lion had the latest java.

I have just installed Mountain Lion and now cannot access Minecraft. It is telling me I need another Java plug in, but I thought that Mountain Lion includes the latest java. Has anyone else experienced this and do they know how to get the plug in?

Hello:
Have you run software update after the install?
In any event, go to utilities>java preferences. Open that and follow the prompts, if any.

Java Plug-in not working with WinXP SP2 Registry Key Missing Error Pop-Up

I have WinXp PRO with SP2 and the Oct 12 Security Update Patch for SP2 loaded and I went to my Control Panel and saw that the JavaRuntime Environment 1.4.2_04 icon was missing and when I went to click the Java Plugin icon to Open it, I got the following message in a Error Pop-Up window:
The system cannot find the registry key specified:
HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java pPlug-in\1.4.2_04\JavaHome
I then went to Chage Access Program Controls and when I clicked on the Change box for the program, it wanted me to re-install the whole environment.
Prior to doing this, and potentially screwing up my MS winXp environment, I went to the Sun support page for Java Plug-in and I did get the dancing elmo appear as they said I would but I noticed that my environment was MS VM, not Java and that I was out of date and a newer update was avaliable.
The downloads page for the plug-in states clearly that it supports WinXp SP1 and NOT SP2.
SO, my question is, do I need to re-install anything or wait till the whole SP2 issue and java with (BITS) issue gets resolved and just use the MS VM engine during my browsing time? Is there a workaround and what impact will this have on my system? I am not developing Java Apps but am a Power user in Windows who is wondering if applets and general browsing might be easier, faster and more fluid if the Java Runtime was enabled as opposed to the MS VM solution?
Any ideas or thoughts on this very timely issue would be greatly appreciated as I see others have tried to post related issues but none that succinctly combines what I have asked for here in this post.
Thanks from NYC -Phil

did you know that XP SP2 has so many technical problems? try SP1 or contact the WindowsXP Vendor

Java Plug-in 1.4.2_01 error

Hi,
Sometimes when I access certain websites with java programs I get the following pop-up error
"Java Plug-in 1.4.2_01 is not installed properly". It then asks if I would like to open a new browser as the one I'm using apparently won't support the version of java needed for the applet.
I'm using IE 6.0
When I click on the Tools --> Sun Java Console I get the same Java Plug-in error.
I have installed:
Java(TM) 2 SDK, Standard Edition Version 1.4.2
Java(TM) 2 Runtime Environment, Standard Edition Version 1.4.2 (j2re1.4.2_01)
in different folders. Could that be the conflict?
Should I just uninstall/delete both of them and reinstall another version?
Any help is much appreciated!

Yes, I would uninstall the JRE and the SDK and reinstall the latest version, J2SE SDK 1.4.2_04. In my experiences, during install the setup application asks me if I want to use this JVM with the browsers it finds, IE and Netscape. I always leave the boxes checked for both browsers and that seems to do the trick for me.

Java Plug-in Update on Oracle AS

Hi All,
On my test Oracle Application Server where I have Discoverer installed, I updated my configuration.xml file, but when I log into the Application Server Control as ias_admin and navigate to the Discoverer Plus (Application Server: disccoverer.appsvmrpt02.cm.charter.com > Discoverer > Discoverer Plus), I receive the following error:
An error occurred:oracle.disco.oem.configuration.DiscoConfigurationException: Cannot find element: configuration See base exception for details. Resolution: See base exception for details. Base Exception: java.lang.NullPointerException null
Here is my jvm element from my configuration.xml file which I updated:
after:
<jvm name="sun" classid="clsid:CAFEEFAC-0016-0000-0012-ABCDEFFEDCBA" plugin_setup="http://appsvmrpt02.cm.charter.com:7778/jpi/jre6u12.exe" version="1.6" versionie="1,6,0,mn" type="application/x-java-applet" plugin_page="http://java.com" disco_archive="disco5i.jarjar" d4o_archive="d4o_double.jarjar" />
before:
<jvm name="sun" classid="clsid:CAFEEFAC-0014-0002-0006-ABCDEFFEDCBA" plugin_setup="\\cm\sys\Tools\MIS_Utilities\Java\Java 6 update 12\javainstall.exe" version="1.6" versionie="1,6,0,mn" type="application/x-java-applet" plugin_page="http://java.sun.com/products/archive/j2se/1.4.2_06/index.html" disco_archive="disco5i.jarjar" d4o_archive="d4o_double.jarjar" />
I did confirm that this element is well formed prior to inserting/modifying.
I also tested the plug-in url by placing it in my browser and this works fine.
I tried to rollback, but I get the following error when I navigate to the Oracle AS Discoverer Plus Configuration page:
An error occurred:oracle.disco.oem.configuration.DiscoConfigurationException: Cannot find element: configuration Base Exception: The requested Entity was not found. Entity Path [system/configuration] not valid. Check log to see if the PlugIn was loaded Resolution: Contact Oracle Support.
I did submit a SR and Oracle is advocating applying CP6. One would think we should be able to rollback (our production box works fine with this set-up).
Any suggestions?
Thanks,
Patrick
p.s. Here is my configuration:
System configuration:
OracleBI Discoverer 10g (10.1.2.3)
Oracle Business Intelligence Discoverer Plus 10g (10.1.2.55.26)

Patrick,
1. You may want to use the family classid so that it is not coded to a specific minor version
"clsid:CAFEEFAC-0016-0000-0012-ABCDEFFEDCBA" vs. "clsid:CAFEEFAC-0016-0000-FFFF-ABCDEFFEDCBA"
See Oracle's technical note:
Recommended Client Java Plug-in (JVM/JRE) For Discoverer Plus 10g (10.1.2) (Doc ID 465234.1)
Shouldn't matter too much (for minor version vs. family version) since all Java applets are run using the latest version of the JRE software that is installed on the system.
2. The error
"An error occurred:oracle.disco.oem.configuration.DiscoConfigurationException: Cannot find element: configuration Base Exception: The requested Entity was not found. Entity Path system/configuration not valid. Check log to see if the PlugIn was loaded Resolution: Contact Oracle Support. "
This seems to indicate that something corrupted the Application Server Control plugin. Applying CP6 likely laid down a new correct file. You are right it likely could have been resolved also by rolling back and re-applying the same cumulative path.. This may have been caused by modifying the UIX files. I don't think it is related to the configuration.xm, if you had a bad line in there, you would see an xml parsing error.
3. Speaking of UIX files.
"Lastly, he had to modify the discovererplus_config.uix so that the Java Plug-in drop-down on the Discoverer Plus configuration page would show the Java 1.6 plug-in option. I did not see much documentation on this step."
Just a "heads-up" / reminder for you to document your change in the uix file as any new patch installed after this will overwrite the UIX file. You are correct, there really is not documentation on changing that hard-coded version number in Application Server Control. It likely should have been developed generically with no version number hard-coded. Probably should be an enhancement request.

Steve

JVM vs JRE vs Java Plug-In and Yahoo Chat

Hi
I am a little confused as to what is required in the browser to run an applet.
Do I require JVM installed in my browser?
Do I require Java Plug-In installed in my browser?
Do I require JVM installed in my browser?
What is the difference between these three?
My second question is about the version of JDK to use while developing Java Applets. I am planning to make a Chat Application similar to Yahoo chat. For that I made a beta version using JDK 1.4.2 but now the problem is that most of the client browsers have old version installed for e.g. 1.1.4 by Microsoft or 1.2 by Sun.
In this case almost every user that uses my chat applet has to download the latest version from http://java.sun.com/getjava otherwise it the chat applet doesn't work on their browser. And I don't want this to happen because most of the time it takes ages to download and install the latest Java version on client browser. Yesterday on Pentimum 4 having 512 MB RAM and Windows 98 it took almost 45 minutes to download and install which is unacceptable.
If you see the Yahoo chat http://chat.yahoo.com you will see that it is developed in such a way that it supports almost all the browserd without having to install the latest version. This is what I want to achieve and I am looking from your input as to how do I make sure that the client doesn't need to install the latest version (or atleast very few clients need to install latest version). Do I need to make this chat application in an old JDK version for e.g. 1.1.6?

ooppss....I little mistake in my above post. The third question is
Do I require JRE installed in my browser to run applet?

Null pointer Exception on java plug-in , using Mutity language...

this message is plug-in do not download class archive in client System cache... because of VM cannot know user.home directory...
you can find that java plug-in does not support mulity language to see the next sentence.
"user home = C:\Documents and Settings\��????"
in this reason i found a problem in communication JApplet and java-script by using cookies...
How can I solve this problem...( i must use Multi language login ID plz.....)
have a nice day!!!

Java plug-in not working in multi-server instance

I am having problems getting the Sun Java plug-in to work
when attempting to use the Browse Server button within the CF
Administrator for directory browsing features such as the Code
Analyzer, Verity Collections,etc., in a multi-server instance
setup. The plug-in works fine within the first instance. For all
the other instances (2 through n), the Java plug-in doesn't do
anything except show an image of a sun with the words Java Sun
Microsystems with the rays of the sun going around and round.
We are using CFMX 7.0.1 with the Sun Java plug-in 1.5.0_06.
Anyone else experience this problem before?

First, you need to get off of Java 1.5 and back to 1.4.2. 1.5
isn't supported yet and breaks stuff.
Secondly, you need to make sure RDS is enabled on all of your
instances.

Unable to run Demos applet in java plug in 1.3.1_04

Hi
This is dipak here, I am try to run sample appplets program from java 1.3 samples and codes page of java.sun.com, but I am getting a security warning saying that "Do you want to install and run Java Plug-in1.3.1_13".
I already install J2RE , i.e. Java Plug-in 1.3.1_04.
Please tell me what i have to do and Java Plug-in 1.3.1_04 is still supported by java1.3 samples and codes or not.
Thanks in advance for help.
Thanks and Regards
Dipsy

Apparently the applet you're trying to run is wanting the more recent version of Java, and is asking you to install it.
The version you have (1.3.1_04) is very old and reached End-of-Life years ago. Updating to Java 5 would probably resolve the issue.

Loaading Java Plug-in

Hi everybody!!
I have an applet that invoque from an HTML file, but when I call the HTML file a message in the toolbar browser appears: " Loading plug-in", then another message appears : " 10% de 580 K 23:43 remainig ....." and in the browser main page a gray window appears with the label : 'loading java applet'. Finally the applet appears.
So, Could you please tell me in detail what is happening from the html file is called to the applet appears ?
Or please, tell me where to find this information....

Sounds like the applet requires the Java plug-in to run and the messages you see are the download of that plug-in. See http://java.sun.com/getjava/help.html for more info. The reason the plug-in is required is that the JVM that comes with the browser does not include all the classes that an applet can use. The choice is either to write applets based on a limited subset of Java that the browser JVM supports, or to require a one-time download of a plug-in (which takes time, as you found out).

Certification forms 6i and Java plug-in

Is certified to use forms 6i + patch 4 with Sun Solaris JDK 1.1.8/Java plug-in 1.3?
or what is the certified version?
Document Oracle Forms Server: Client Platform Support Statement of Direction from October 2000 (on OTN) says that
this is planned. Is it already certified?
Thanks.

Hello,
All you have to do is to copy the .jar file that contains the Java class(es) in the <devsuite>/forms/java/ directory, configur the <devsuite>/forms/server/formsweb.cfg file to add this jar file to the archive_jini tag to indicate where Forms have to load the classes:
archive_jini=frmall_jinit.jar,...,my_jar_file.jar
Then after, you have 2 possibilities:
- the bean does not have any "screen" representation so you can just handle its functions with the Forms internal FBean package functions (no need to put implementation class on the bean area item property)
- it has a screen representation, so you put its implementation class like you did, and you set its properties with the Set_Custom_Property() built-in and get its properties with the Get_Custom_Property() built-in.
