Loading Java Applet

I have a Java file (.jar) that runs fine on my desktop, but when I add it to my files in Dreamweaver and try to run it, it gives me this error:
"Could not find the main class: C:\... Program will exit."
Further, once I upload it online and click on it after it says it has an error, it spits this out:
load: class teatApp.jar not found.
java.lang.ClassNotFoundException: teatApp.jar

I'm using Eclipse to create these .jars and have tried both runnable .jars created from JFrames and .jars created from applets (these don't run on the desktop but do run within Eclipse), but both give me the same error stated above.
Any help to find a solution for my problem would be greatly appreciated!

This is a Java programming question and not a Dreamweaver question. It appears your Java app requires a class file that's found on your local hard drive. I don't know Java but it seems like to get around this problem you need to ensure that the required class file is compiled and included in the final Java "binary" (.jar) file that will be served up.

Cannot load java applets in Safari

I have several accounts on my machine. In one, the one I use most of the time, Safari will not load java applets. I have checked preferences and compared with those set on the other accounts. They are the same, including enabling javva and javascript. I have removed the Safari plist. I have repaired permissions. I have reset safari, cleared history and caches, used Cocktail to clear caches. I have rebooted.
I set up a new test account and it works fine.
What's going on, and how do I cure it?

I will try the pram reset, though I am not confident of it since this problem affects only one account.
On the new account business. I note that when I set up a new account, before I launch safari, there are no files in the Library related to Safari. They are created on the first launch. If I delete them all, then they are recreated on another launch. What if, in the affected user directory, I exported the bookmarks and/or dragged the bookmarks file to the desktop. Then deleted all evidence of safari from the account. I should now have, in effect, a virgin install of safari. Launching it would create all of the necessary files and directories. If safari works with java applets, or does not, I can simply move the bookmarks back in and be no worse off than I was in the beginning.
Any serious fault with that? I am working at home today so cannot do this until I am in the office on Monday.

Loading Java Applet....again

Hi,
I've done a search on this topic and have not been able to resolve the problem.
The problem being that after trying to "Run a Form on the Web" using test.fmx, The loading java applet message stays in the browser indefinitely.
Some have suggested turning on the JInitiator Console to get a better understanding of the problem.
My problem is that when I click the "Show Java Console" and then "apply" in the JInitiator Control Panal nothing happens. I'm completely new to all of this, is there anything else I have to do to display the Java console?
Java consoles aside, any suggestions as what else I can do? When I first run the form I get an "applet loading" message in the browser status bar for a split second, followed by "exception:http://<servername.domain>/forms60java/f60web.jar"
I'm using IE 5.00 and jinitiator 1.1.7.27
Thanks for any help.
Darren

Anyone knows what's the classid of Jinitiator 1.1.7.31?
Thanks a heap for any replies
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by Dhananjay Jawale ([email protected]):
Hi,
Please make sure what Shay has suggested about the correct class id . For Jinitiator 1.1.7.27 it is 093501ce-d290-11d3-a3d6-00c04fa32518
Check your toolbar if you can see a application icon with java cup. If you can get it, maximize it .
This is a known problem with OS like Windows 95.
In my application support, i get calls regarding not able to find the login screen and i help them in same way.
Try it and let us know

Loading Java Applet Failed in CRM 2007 Web Client Marketing

We have recently upgraded our CRM 4.0 sp6 system to CRM 2007. As part of this upgrade we configured the SAP Best Practice Building Blocks. Logging on to the webclient using the user MKT_MAN (assigned business role BP_MKT_MAN) we get an error when trying to run the Marketing Calendar. the error we get is that "Loading Java Applet Failed" the specific applet in question is: Applet com.sap.crm.mkt.calendar.applet.MktCalendar notinited
We have implemented the following SAP notes to try and rectify the issue but with no success:
Note 1177590 - Version 2.0 of Marketing Calendar java applet
Note 1237477 - Marketing Calendar is not displayed, Tensegrity Library
Any ideas as to what can resolve this issue
Thanks in advance
Eddie

Hi Eddie
I have exactly the same problem, using IE 6.0 & JRE 1.4.2_07.
What I have found is that users in my company with the same configuration on their machines, same settings as above can load the Marketing Calendar without issue.
Have loaded the same notes as yourself already.
I have managed to get it to working by switching off my proxy settings entirely. This is fine for testing but of no use for go live.
I have also found that when it does finally load successfully it is incredibly slow in comparison to other functionality within the WEB UI.
Thus far I have logged an OSS Message regarding this matter, could I recommend you do the same, this should encourage SAP that the issue is not isolated.
Good Luck
Arden

Load: class oracle.forms.engine.Main not found Stuck at loading Java Applet

Hi there
I have recently installed App Server 10.1.2.0 on a new machine.
Copied all my forms to an appropriate directory. Set up formsweb.cfg to allow them to run and have attempted to run them.
Unfortunately I get stuck at the Loading Java Applet screen, and in the status bar at the bottom it says :
load: class oracle.forms.engine.Main not found
I have taken a look at the Java Console, and the 2 things that jump out at me are that it appears to be looking for a forms90 directory, which seems odd since I am using App Server 10.1.2.0.2 and Forms Builder 10.1.2.0.2 meaning it should be looking in a forms directory not forms90 directory shouldnt it ?
And also, it mentions class with no proxy, so on looking around the forums it has been suggested that put the proxy details into jinitiator, which I have done, but this has made no difference either.
Can anyone suggest anything else please ?
Java Console log follows.
Thanks a lot

Nothing happening after LOADING JAVA applet

Today since morning I have been facing a problem with my forms....when i complile and run my form... the browser opens with the message loading java applet
But the forms doesnt seems to open....it gets stuck at this particular point..! dont know why...
Note:It was working fine till yestarday

depending on your browser's version, make sure the address you are opening is found in your "safe" list.
If you're using IE make sure you have the address in your trusted sites. Sometimes Windows DEP (Data Execution Prevention) also stops the browser from opening.
Also make sure your network is not blocking the site.

I don't have any experience with GTO's cards, but one would expect they provide a user guide or a data sheet how to load applications.. Reasons could be:
1. Issuer policy to have a certain security level for content management --> raise the security level to C_MAC + ENC
2. Issuer policy this card is static --> no post-issuance

Can't load Java applets in Safari

Ever since I installed Snow Leopard, Safari can't load Java applets. I get a blue Lego brick with a question mark, and a message telling me that Java was not found.
Firefox is unaffected, and I get the same error whether Safari is open in 32-bit or 64-bit mode. Programs written in Java, such as Vuze, are unaffected.

Create another admin user account log into it, and see if the problem persists. If not, the issue's within the original account, usually amongst preference (plist) files. If so, then it's system-wide and reinstalling the 10.6.2 COMBO update, repairing permissions, and restarting should do the trick.

I use win XP home and Internet Eplorer 6

Loading Java Applet Failed : Getting Red "X"

Hi all
I have JRE 1.6.0_07 loaded on my machine. When i try to access a particular website from my machine i can see an orange Java Logo and then after some time i get a "Red" "X" on top left with a message in bottom of browser
"Loading Java Applet Failed".
I am Using IE 6.0.2900.2180.xpsb_sp2...on a Windows XP SP2 Professional .
I also get a Error Message as
"General Exception"
Name - Batchmanage
Java.lang.classnotfoundexception.batch.class
1) However when i disable Options ==> Advance ==> Java(Sun) ==> Use JRE 1.6.0_07 for <applet>
and enable Options ==> Advance ==> Microsoft VM ==> Jit Compiler for VM enabled
Application runs fine.
2) But if i Enable Options ==> Advance ==> Java(Sun) ==> Use JRE 1.6.0_07 for <applet>
and disable Options ==> Advance ==> Microsoft VM ==> Jit Compiler for VM enabled
Applications Give error mentioned above and Red X
3) Similary if i enable Options ==> Advance ==> Java(Sun) ==> Use JRE 1.6.0_07 for <applet>
As well as enable Options ==> Advance ==> Microsoft VM ==> Jit Compiler for VM enabled
Still Application Gives error mentioned above and Red X
For some machines we have observed that it runs fine with Java (Sun) enabled with no Microsoft VM
Any advise or help would be appreciated
Thanks

Loading Java Applet... error

Hi!
When I try to run the Sun demo SwingSet2, IE(5.0) hangs.
First I installed JRE 1.3.1(on advice of the demo site.)
Then it all end up with the text "Loading Java Applet..."
in the grey box.
I have also tried to install different JRE versions but I just can't run a Sun demo applet (neither my own applets).
I would be very happy if someone could solve this problem.

InternetExplorer: 5.00.3315.1000
Windows 2000

Hi:
I just have a comment and one last suggestion.
First, I am able to run the SwingSet2Plugin.html with both IE5.0 and IE5.5 on Windows 98SE. I am currently using JDK/JRE1.3.1. A few months ago, I upgraded to 1.3.1_02 and found that some of my applets stopped working for no apparent reason, so I went back to 1.3.1.
If your applets stopped working because of an upgrade in JDK or JRE and you're using Windows, I suggest that you make sure that the previous version of the JDK/JRE were cleanly removed from the system. You can verify this by going to the Control Panel and click on Add/Remove Program to see if there are multiple versions of the software. Also, click start, run REGEDIT and look in the following folder for any remaining references to the JDK/JRE:
HKEY_LOCAL_MACHINE-->Software-->Microsoft-->Code Store Database-->Distribution Units
look for something with {...} or the prefix {CAFE... and remove any remaing older versions (I know most people wouldn't touch regedit with a ten-foot pole but this may be the only way to solve the problem).
I use a lot of applet and am particularly interested in cases where ppl have problems with using applet and find out how the problems are resolved. If my suggestions worked or if you find out what caused the problem, I would appreciate your sharing the info.
Good Luck!

Thanks You.

In one of my project i tried to load applet using the <jsp:plugin> tag but failed. Since i had less time so i have not done the R&D instead i called the applet as
<applet id="MyApplet" code="MyApplet.class\" archive=\"MyApplet.jar\" width=5 height=3/>and it worked fine for me. You can try this method.
NOTE: My applet jar file was in the same directory of my JSP page

Unable to clear java cache and also unable to load JAVA Applets when QTP installed in PC

Hi,
I am facing a problem when QTP 11.0 along with Java 6 Update 22 and Java Plugin installed in the PC. The Java Applets are not being loaded in the webpages, when I try to load it through QTP, but when I try to load the applets manually that is working fine. Can anyone suggest any kind of solution for this. All the setup was being run on 32-bit and 64- bit PC's.
Thanks in advance,
Waiting for the reply.

start the weblogic server with the command startWeblogic. And then start the SOA server from Admin console.This is the issue. For starting servers from console, you need to configure node manager. Start SOA servers from command line using command startManagedWeblogic (as mentioned in Quick Start Guide for BAM server).

Can't load java applet? help please?

I am trying to load a java applet after an upgrade - but security settings are blocking it - please help

Java is no longer supported on Mac OS X 10.6. The security of Java has been found to be so bad, you are lucky to get any Apps that work wtih it. You need a minimum of Mac OS X 10.7.3 to run the latest Java applets and that using Java from http://www.java.com/ See the user tip here to optimize Java under 10.6.8
