3D Applet not running in IE, Mozilla, etc ...

Hi,
I have programmed an 3D applet with the J3D engine.
When I start the .jar everything is fine.
I have created the JAR with JBuilder and a main-class definition.
Now I want to run the JAR as an applet.
The HTML I have written seems to be OK because the brwosers say "Applet blabla started."
The applet area just stays white ...
Where can I find something like a log of the starting process or the errors that occur in my java app?
Thanks in adavnce!

I got some reasonable solution from some other forum.
The Problem is with the VM. The JVM is crashed with MS VM.
That is why the browser diplays class not found error.
This is because the MS VM is not allowing the JVM to look for .class files.
This will happen for java 1.4.x .
If you use HTML converter (converting the applet to object) it will work.
But the Optimal solution is compile your applet file with -target option.
e-g
javac target 1.1 HelloWorld.java
It is the most efficient way to avoid such problems with IE while running the applets.
I Thank you all for your solutions.

Applet - not rendering n Browser - Mozilla / IE - Help

Hi,
I have following code in AnotherHello.html in
<html>
<body>
<applet code="AnotherHello.class" width="300" height="150"></applet>
</body>
</html>and the following in AnotherHello.java
import java.awt.*;
import java.applet.Applet;
class AnotherHello extends Applet
     public void paint(Graphics gr)
          setBackground(Color.lightGray);
          gr.drawString("Hello", (300/2 - 40/2), (150/2 + 40/2));
}When I run it using Mozilla or IE it only shows the HTML code in the browser, it does not get me the applet on to the screen. Could somebody help me in figuring out the problem.
Thanks in advance.

I have only these two browsers so dont know about
other browsers.
No it does not run in applet viewer also.
I have the class file compiled in the same directory
as in the java and the html file.
I am able to see applets from various websites in my
mozilla browser, which would mean that applet is
enabled.
I am not sure what could be the problem.
Please do let me know.Sounds like it should run then. Maybe it is, but what it's drawing is "invisible" - what about removing that setBackground call, or set it to a different color. If you get a different result, then it is running.

QMASTER hints 4 usual trouble (QM NOT running/CLUSTEREd nodes/Networks etc

All, I just posted this with some hints & workaround with very common issues people have on this forum and keep asking concerning the use of APPLE QMASTER with FCP, SHAKE, COMPRESSOR and MOTION. I've had many over the last 2 years and see them coming up frequently.
Perhaps these symptoms are fixed in FCS2 at MAY 2007 (now). However if not here's some ROTS that i used for FCP to compressor via QMASTER cluster for example. NO special order but might help someone get around the stuff with QMASTER V2.3, FCP V5.1.4, compressor.app V2.3
I saw the latest QMASTER UI and usage at NAB2007 and it looked a little more solid with some "EASY SETUP" stuff. I hope it has been reworked underneath.. I guess I will know soon if it has.
For most FCP/COMPRESSOR, SHAKE. MOTION and COMPRESSOR:
• provide access from ALL nodes to ALL the source and target objects (files) on their VOLUMES. Simply MOUNT those volumes through the APPLE file system (via NFS) using +k (cmd+k) or finder/go/connect to server. OR using an SSAFS such as XSAN™ where the file systems are all shared over FC not the network. YOu will notice the CPU's going very busy for a small while. THhis is the APPLE FILE SYSTEM task,,, I guess it's doing 'spotlight stuff". This goes away after a few minutes.
• set the COMPRESSOR preferences for "CLUSTER OPTIONS" to "Never copy source to Cluster". This means that all nodes can access your source and target objects (files) over NFS (as above). Failure to to this means LENGTHY times to COPY material back an forth, in some cases undermining the pleasure gained from initially using clustering (reduced job times)
• DONT mix the PHYSICAL or LOGICAL networks in your local cluster. I dont know why but I could never get this to work. Physical mean stick with eother ETHERNET or FIREWIRE or your other (airport etc whic will be generally way to slow and useless), Logical measn leepin all nodes on the SAME subnet. You can do this siply by setting theis up in the system preferences/QMASTER/advanced tab under "Use Network Interfaces". In my currnet QUAd I set this to use BUILT IN ETHERNET1 and in the MPBDC's I set this to their BUILTIN ETHERNET.
• LOGICAL NETWORKS (Subnet): simply HARDCODE an IP address on the ETHERNET (for eample) for your cluster nodes andthe service controller. FOr eample 3.1.1.x .... it will all connect fine.
• Physical Networks: As above (1) DONT MIX firewire (IPoFW) and Ethernet(IPoE). (2) if more than extra service node USE A HUB or SWITCH. I went and bought a 10 port GbE HUB for about $HK400 (€40) and it worked fine. I was NEVER able to get a stable system of QMASTER mixing FW and ETHERNET. (3) fwiw using IP of FW caused me a LOAD of DISK errors and timouts (I/O errors) on thosse DISKs that were FW400 (al gone now) but it showed this was not stable overall
• for the cluster controller node MAKE SURE you set the CLUSTER STORAGE (system preferences/QMASTER/shared cluster storage) for the CLUSTER CONTROLLER NODE IS ON A SHARED volume (See above). This seems essential for SHAKE to work. (if not check the Qmaster errors in the console.app [see below] ). IF you have an SSAFS like XSAN™ then just add this cluster storage on a share file path. NOte that QMASTER does not permit the cluster storage to be on a NETWORK NODE for some reason. So in short just MOUNT the volume where the SHARED CLUSTER file is maintained for the CLUSTER controller.
• FCP - avoid EXPORT to COMPRESSOR from the TIMELINE - it never seems to work properly (see later). Instead EXPORT FROM SEQUENCE in the BROWSER - consistent results
• FCP - "media missing " messages on EXPORT to COMPRESSOR.. seems a defect in FCP 5.1 when you EXPORT using a sequence that is NOT in the "root" or primary trry in the FCP PROJECT BROWSER. Simply if you have browser/bin A contains(Bin B (contains Bin C (contains sequence X))) this will FAIL (wont work) for "EXPORT TO COMPRESSOR" if you use EXPORT to COMPRESSOR in a FCP browser PANE that is separately OPEN. To get around this, simply OPEN/EXPOSE the triangles/trees in the BROWSER PANE for the PROJECT and select the SEQUENCE you want and "EXPORT to COMPRESSOR" from there. This has been documented in a few places in this forum I think.
• FCP -> COMPRESSOR -> .M2V (for DVDSP3): some things here. EXPORTING from an FCP SEQUENCE with CHAPTER MARKERS to an MPEG2 .M2V encoding USING A CLUSTER causes errors in the placement of the chapter makers when it is imported to DVDSP3. In fact CONSISTENTLY, ALL the chapter markers are all PLACED AT THE END of the TRACK in DVD SP# - somewhat useless. This seems to happen ALSO when the source is an FCP reference movie, although inconsistent. A simple work around if you have the machines is TRUN OF SEGMENTING in the COMPRESSOR ENCODER inspector. let each .M2V transcode run on the same service node. FOr the jobs at hand just set up a CLUSTER and controller for each machine and then SELECT the cluster (myclusterA, hisclusterb, herclusterc) for each transcode job.. anyway for me.. the time spent resolving all this I could have TRANSCODED all this on my QUAD and it would all have ben done by sooner! (LOL)
• CONSOLE logs: IF QMASTER fails, I would suggest your fist port of diagnosis should be /Library/Logs/Qmaster in there you will see (on the controller node) compressor.log, jobcontroller.com.apple.qmaster.cluster.admin.log, and lots of others including service controller.com.apple.qmaster.executorX.log (for each cpu/core and node) andd qmasterca.log. All these are worth a look and for me helped me solve 90% of my qmaster errors and failures.
• MOTION 3 - fwiw.. EXPORT USING COMPRESSOR to a CLUSTER seems to fail EVERY TIME.. seems MOTION is writing stuff out to a /var/spool/qmaster
TROUBLESHOOTING QMASTER: IF QMASTER seems buggered up (hosed), then follow these steps PRIOR to restarting you machines.
go read the TROUBLE SHOOTING in the published APPLE docs for COMPRESSOR, SHAKE and "SET UP FOR DISTRIBUTED PROCESSING" and serach these forums CAREFULLY.. the answer is usually there somewhere.
ELSE THEN,, try these steps....
You'll feel that QMASTER is in trouble when you
• see that the QMASTER ICON at the top of the screen says 'NO SERVICES" even though that node is started and
• that the APPLE QMASTER ADMINSTRATOR is VERY SLOW after an 'APPLY" (like minutes with SPINNING BEACHBALL) or it WONT LET YOU DELETE a cluster or you see 'undefined' nodes in your cluster (meaning that one was shut down or had a network failure)..... all this means it's going to get worse and worse. SO DONT submit any more work to QAMSTER... best count you gains and follow this list next.
(a) in COMPRESSOR.app / RESET BACKGROUND PROCESSES (its under the COMPRESSOR name list box) see if things get kick started but you will lose all the work that has been done up to that point for COMPRESSOR.app
b) if no OK, then on EACH node in that cluster, STOP the QMASTER (system preferences/QMASTER/setup [set 0 minutes in the prompt and OK). Then when STOPPED, RESET the shared services my licking OPTION+CLICK on the "START" button to reveal the "RESET SERVICES". Then click "START" on each node to start the services. This has the actin of REMOVING or in the case where the CLUSTER CONTROLLER node is "RESET" f terminating the cluster that's under its control. IF so Simply go to APPLE QMASTER ADMINISTRATOR and REDFINE it. Go restart you cluster.
c) if step (b) is no help, consult the QMASTER logs in /Library/Logs/Qmaster (using the cosole.app) for any FILE MISSING or FILE not found or FILE ERROR . Look carefully for the NODENAME (the machine_name.local) where the error may have occured. Sometimes it's very chatty. Others it is not. ALso look in the BATCH MONITOR OUTPUT for errors messages. Often these are NEVER written (or I cant find them) in the /var/logs... try and resolve any issues you can see (mostly VOLUME or FILE path issues from my experience)
(d) if still no joy then - try removing all the 'dead' cluster files from /var/tmp/qmaster , /var/sppol/qmaster and also the file directory that you specified above for the controller to share the clustering. FOR shake issues, go do the same (note also where the shake shared cluster file path is - it can be also specified in the RENDER FILEOUT nodes prompt).
e) if all this WONT help you, its time to get the BIG hammer out. Simply, STOP all nodes of not stopped. (if status/mode is "STOPPING" then it [QMASTER] is truly buggered). DISMOUNT the network volumes you had mounted. and RESTART ALL YOUR NODES. Tis has the affect of RESTARTING all the QMASTERD tasks. YEs sure you can go in and SUDO restart them but it is dodgy at best because they never seem to terminate cleanly (Kill -9 etc) or FORCE QUIT.... is what one ends up doing and then STILL having to restart.
f) after restart perform steps from (B) again and it will be usually (but not always) right after that

Warwick,
Thanks for joining the forum and for doing all this work and posting your results for our benefit.
As FCP2 arrives in our shop, we will try once again to make sense of it and to see if we can boost our efficiencies in rendering big projects and getting Compressor to embrace five or six idle Macs.
Nonetheless, I am still in "Major Disbelief Mode" that Apple has done so little to make this software actually useful.

Applet not running in the broweser.

Hello everyone I have a problem that is bugging me.
in my pc at home i have operating system window xp i have oracle9i installed and also java and j2ee and version of internet explorer is 6.0
.there is no proble running html pages but the problem is the applet are not running in the broweser even the java demo from sun is not running
.when i try to run the applet a dialog box appears and shows this
" jvm not find Download now" i do not have internet connection.
and one more thing i want to down load or save file in webserver
i donot know whether my pc is having default webserver but when i type this "http://localhost" a page of oracle is display listing jserver ,appache server and so many thing.
do i have a webserver that can be used by me for java program(adv java) or i have to get one .as i told you there is java1.3 and j2ee1_2_3
something like this i donot remember is there no default webserver along with them .how can i use them for my java programe .
let me remind you the applet not getting downloaded in the browser is a bigger problem for me.
i appreciate your concern please help me out
have a nice day bye.

1} The applet is not getting loaded in my internet
browser.Error messages? Are you sure your setup is correct? Search. "Applet not working" usually has only a small range of reasons, all well-covered here.
2}why the oracle page is displayed when i type
"http://localhost".
Maybe because you have some Oracle webserver?
3} Do i have any default webbrowser in my system.Yes. The one that opens when you double-click on an HTML page.

thanks.

My Applet not running in java not installed systems.

dear sir/madam,
i have an applet which uses java.awt.* and java.awt.event.* classes, is running in systems with J2SE installed. but it is not running in systems with java enabled browsers without J2SE installation.
i want my applet to be run in all java enabled browsers without J2SE also.
how to make my applet work.
thanks in advance.
-- ks_moses

install J2SE to develop Java programs..
install JRE to run your Java Programs
To run your applets into such a browser, you must have a plugin installed on that browser to run your applet, so install JRE(Java Runtime Environment), it will install the Java plugin automatically so you can run your applets, GoodLuck

Applet not running in local browser

I can run any applet from web.
I can run any applet in appletviewer.
But I can not run applets in browser from local html file.
I can not run even the demos that came with de SDK 1.4.1_01.
Can anyone give me some hint?
Maybe is very obvious but I ca not see it.
Thank you very much.

the hello.java file is:
import java.applet.Applet;
import java.awt.Graphics;
public class hello extends Applet {
StringBuffer buffer;
     public void init() {
     public void start() {
     public void stop() {
     public void destroy() {
     public void paint(Graphics g) {
          //Draw a Rectangle around the applet's display area.
          g.drawRect(0, 0, size().width - 1, size().height - 1);
          //Draw the current string inside the rectangle.
          g.drawString("Hello", 5, 15);
The hello.html file is:
<html>
<body>
Applet should be there
<br>
<applet code="hello.class" width=200 height=200>
No applet
</applet>
</body>
</html>
hello.html and hello.class are of course in the same folder.
If I modify the .html file acording to OBJECT tag specifications for Java Plug-In the same applet runs OK in the browser (IE5.0 ).
I forgot to tell that I have installed the last version of SDK j2sdk1.4.1_01
<html>
<body>
Applet should be there

Applet Not Running in IE. Need IE settings for running applet.

Hi
I am facing a problem with Applet while running in IE-6. The problem is very simple; Applet is not running in IE-6, not even a simple applet which displays just a Label.
I am using Java Version 1.4
Settings for IE is as follows
Java (Sun)
CHECKED Use Java 2 v1.4.0 for <applet>
Microsoft VM
CHECKED Java console enabled
NOT CHECKED Java logging enabled
CHECKED JIT compiler for virtual machine enabled
The applet is running in Appletviewer and run in IE in some other machine. The problem is in my browser and Java versions.
If I start the applet in IE it is not showing even Jave Console (which is enabled).
In Java Plugin (Control Panel) I enabled Show Console and set MSIE checked.
What should I do to solve such a stupid problem with my IE. I have updated my JVM and IE twice but yet to wait for solution.
Your help is worshipfully appericated.

Applet not running on MAC OS X

My applet works fine on windows but when my client run my applets on MAC OS Browser then it gives error on status bar like "Applet Not Loaded ".
So How can i solve this problem . helpful advice is appreciated.

The first advice given was the best advice you will get at this stage.
OTOH, the problem might be that the compilation options used on Windows were for a 1.6+ JRE, whereas the Mac is running a 1.5 JRE.
If that is the case, the relevant questions become..
How do you compile the applet (e.g. IDE, IDE with Ant build script, command line..)?
What SDK version are you using?
What compilation options are used (the important ones here are -source -target and -bootclasspath )?
What [java version|http://pscode.org/prop/?prop=java.version] is the Mac using?
Also note that many things* can be determined if you provide an URL to the applet.
* Especially if someone has a Mac and can report the error.

Applets not running with IE6

Using IE6 I can't get any applets to run on any web page. Its seems the Microsoft VM is not functioning correctly. Is there some setting that controls this. I do not want to use the Sun VM. My OS is Win 2000.
Thanks

Go to your preferences, and find the java page. Check to see that java is turned on.
If there is no java page, you'll need the plug-in.

Applet not running Jama Package.

Hello! I am trying to create an applet which at some point should solve a linear system. I tried using the Jama Package. I have written a program which does exactly the same thing as the applet and everything works fine.However when i try to run the applet i get a "java.lang.NoClassDefFoundError : Jama / Matrix " error.
In the applet code i have imported jama package. Any ideas what is wrong and the appletviewer cannot see the Jama.Matrix class?
Thanx in advance for any answers...

A description of the ERROR from the error's API:
Thrown if the Java Virtual Machine or a ClassLoader instance tries to load in the definition of a class (as part of a normal method call or as part of creating a new instance using the new expression) and no definition of the class could be found.
The searched-for class definition existed when the currently executing class was compiled, but the definition can no longer be found.
Typically caused by your not making the class available - that is, it's not on your machine (or is, but in a location such that it can't be found.)
Put a copy in the correct location.

Applet not running

I'm presently using the Java Tutorial downloaded recently, but I counld'nt run tha Applets because Java plug in is not installed. I'm using windows XP Proffessional . Is the Plug in not included with j2sdk1.4.2 (net beans included). How do I get the applets running?

If you don't see a Java Plug-in entry in the Control Panel, go to http://java.com/en/index.jsp and click "Get It Now". This initiates an automatic install of the Plug-in.

what i wann that when i run this code in netscape browser that it won't ask the user to download the plugin for the applet it should automatically download plz do me favour and send me solution thanks

Hello.
Due to firewall issues I cannot state for certain if I am having a similar behaviour to yours. It appears that Netscape( 7.1 ) attempts to resolve to plugins.netscape.com irrespective of the pluginspage attribute ( if it resolves further I cannot see it due to firewalls ). IE appears to try and autoupdate ( based on the firewall challenges ).
You could try and provide a conditionally constructed link ( with information about the JRE failure ) to the JRE of choice between comment/embed/object elements. It is not the solution you asked for, but a potential alternative.
Regards,
James.
