Win98 need to resize applet viewer to see forms client

Is there any work around that will aliviate the problem of needing resize the applet viewr (JInitiator) manually to see the java applet?
This is consistent bug and it seems to appear on all of our Win98 clients (WinNT works fine) in both IE 5.0 and Netscape 4.0

There is a work around for this problem by using the resize_window(FORMS_MDI_WINDOW, height, width) you can force the refresh of the applet window. The ability to use the resize_window on the MDI window web deployed was supposedly just made available with patch 5. I had the same problem and this fixed it for me.

Calendars not showing, need to keep switching views to see changes

When I open iCal the 'Calendars' panel is blank, and no events appear at all. If i select a different view (eg. 'day') the the events mysteriously appear, but the calendar panel remains blank.
When I double click to create a new event, nothing appears in the calendar, until i switch views again, and then if I try to delete an event, it stays visible until - you guessed it - I change views.
All this makes it very hard to edit and create new events...

Me too. The Calendar list on the left shows no calendars. I cannot create new calendar. When I try to import data from Entourage, nothing happens even though I see a progress bar.
I had seen my calendars before. I had imported events from Entourage, but they were duplicated. I tried to delete the events, but may have deleted the calendar.

Applet Viewer

Greetings,
I just started studying java at my vocational school and i'm studying from a book that was published by The Oracle Online Academy. But anyways, my issue is that inside the book they have a little screen shot of what I should be seeing. They are using an Applet Viewing program instead of the standard Command line utility. I'm looking for the program that is used to view programs. Maybe even a GUI for compiling and viewing. Please reply if you know where I can find either of these utilities.
Mike Bailey

I think a little clarification is in order.
There are two kinds of java programs - applets and applications.
Applets are viewed through a html page using either the browser or the "appletviewer" utility
that comes with the jdk.
You cannot run applications with the appletviewer. That's why it is called Appletviewer.
Java applications on the other hand are run through the command line and may or may not
contain a gui - it depends on your program. The whole idea of having a gui to run java applications
defeats its purpose so there aren't any. Java applications - are always run from the command-line
using the "java someprogram" command.
The last thing which you asked for - a gui for compiling and viewing, however, is available. There
are numerous such tools and they are called IDE's (integrated development environments). They
allow you to compile and even run your programs...they look as if they run an application within
a gui but it actually gets run through the command line.
Check out http://www.gExperts.com for a IDE called Gel. Its small and powerful.
In retrospect, you need both the appletviewer (equivalent of a browser as far as applets are
concerned) and a command-line which is capable of running applications.
If you are so interested in running a gui version - why don't you write your own...you'll see they
are relatively easy...just go to..

Do I need to resize the sparsebundle file after migrating to new larger AirPort Time Capsule?

Just upgraded my Airport Time Capsule from an old 1TB to a new 2TB version.
I have migrated the sparse.bundle file by using the ethernet method but now I want to know if I need to resize the file using Disk Utility or does it happen automatically? If it doesn't resize automatically then Apple should at least have some option to automate this process as it seems a natural request.
Over time people would want to continue using their same old back up and just allow the file to get bigger as it is moved onto a newer larger device and still have access to all the previous old backups all on one device/system.

It should continue to resize automatically or would if Yosemite worked properly.. since TM in Yosemite is lousy it might well need you to fix it.. It isn't hard.

Help needed in writing custom views for rendering new HTML tags

Hi
I am in the process of making a sort of HTML editor using the JEditorKit and all,now i need to write a view which will display bi-directional text(text in reverse order),well i am not being able to get to the test at all,i don't know how to get to the text in the element being supplied to my ViewFactory.
Anyone who knows anything about what i am talking here please help me,i am open to any suggestion,anything,i am in a real mess here,please help

Hi,
You dont need any coding to set the changed value back to the context attribute.
Since you have mapped the context attribute in the DisplayView and EditView to a context attribute of component controller. So after viewing the name in your DisplayView when you navigate to EditView onActionChange,you can change the value.When you cahnge the value and submit the new value that is entered is update across the component controller and DisplayView context.
To see this create a action onActionSubmit in EditView and navigate to the DisplayView, you will see the updated value.
In webdynpro framework when the value of a context attribute is changed, then the value gets updated across all views to which the context attribute is mapped.

Applet works in applet viewer but not in website.

I am an experienced programmer, but new to java (second week). I have made working client/server chatroom in java that works when I use the applet viewer, but when trying to run the applet in an html file, I get this error.

I am trying to connect an applet to a server application run on my computer. The server application is run in the eclipse ide, but I doubt that makes a difference.
When connecting to the server from the client run through the eclipse ide with the app viewer, everything works fine. When making an html file for the app and running it also on that computer it fails.
I tried using localhost instead of my internal ip address, and it gave the same errors. I will try signing next, but there must be a way to get this to work without that.

AccessControlException when run in IE or Safari, but not Applet Viewer

My applet requires the use of a txt file as input. The txt file need only be read, and is always in the same directory as the class files and the web page the applet's running in. For a while now, there have been no problems with reading the txt file; however, recently, I've been getting a "java.security.AccessControlException: access denied (java.io.FilePermission *insert filename here* read)" error. Furthermore, this error only comes up when I run the applet in Internet Explorer or Safari; when I run it in the applet viewer, it works perfectly. On top of this, when I went to the tutorial suspecting that the problem had something to do with thread management, I noticed that all three of the applets on page http://java.sun.com/docs/books/tutorial/essential/threads/index.html of the tutorial generated errors, which may or may not indicate that the problem lies in my browsers; frankly, I'm not sure. Any help that you people can give me would be greatly appreciated!

Applets can not read from the filesystem unless you set up policy or sign the applet (or both)

If you applet needs to read a file that is in the same location as the html file and applet why not use the
URL object?

Works in applet viewer but not in internet explorer

I origionaly posted this on devshed. I got 55 views but no replies. It seems to be a common problem to which no one knows the answer. Surprise me :O)I'm sure this is a really common but there seems to be surprisinly litttle on the web about it.
I developed a game applet a while ago in applet viewer and am now thinking about putting it on my web site. However I have found that it doesn't work in internet explorer. I can browse other sites using Java fine. There is clearly just something about my applet that ie doesn't like.
Does anyone have any suggestions? What sort of things upset ie?
All help very much apreciated, you are very nice people
Flo.

There must be some thing that tells you it isn't working. You should tell us so we don't have to guess. Does the browser hang? Do you get an error? Did you try opening the Java Console to see if there were any messages? I am guessing that your code is using something that the security level of an Applet does not allow (but appletviewer does allow).

Applet viewer / mozills / netscape6 hang from time to time

hi list!
we are using a 3 tier setup
(db <--> forms server <--> client with appletviewer)
the database server runs on solaris, the forms server and the clients are running debian stable (woody) (clients use j2sdk1.3)
the forms server is version 9.2. from time to time the applet viewer (or mozilla or netscape; doesnt matter) just hang. from time to time here means like 4 times in the last 2 weeks. the progress indicator in the right lower corner moves from side to side but nothing happens, the gui doesnt get updated anymore and i have to kill the task and any uncommited info is lost :((( . in the server logs i can find this:
[Thu Nov 14 11:55:18 2002 CET]::Client Status [ConnId=0, PID=647]
>> Network connection to client failed: timeout on connection
Possible causes include a network failure or client termination
well, i know that its not a hardware prob since with a 8i client installed everything works perfectly.
i have also tried to use j2sdk1.4 from sun.com but the appletviewer from this version behaves very strangely and keyboard input is often being misinterpreted.
what is considered the most stable client setup for linux clients?
am i overseeing something?
do i have to make any special configuration on the clients?
best regards, armin

Runtime error in Applet only appears when running through IDE applet viewer

Java 5.0
Netbeans 4.1
Linux (Suse 9.3)
I only started getting this error when I set the data loading and initialization classes into a separate thread. (the data loading and init is currently just using dummy test data within the class, nothing is loaded from external files as of yet)

Is this an error I should be worried about, since it only comes up within the IDE?

Thanks for the reply. I am new to this topic area (though pretty good a programming in general...), so forgive me the query below is offbase.
The applet is unsigned. For what it is worth, the applet code and the database are stored on the same machine. However, I can see where a client running the applet is a remote user and so the system may view this as a different source of code (IP/DNS).User has nothing to do with it.

Would this be typical of the problem you describe?
No. You will get an exception for the problem I discussed. The problem you have suggests either something else is wrong or you are eating an exception and then attempting to continue.
And secondly, what is a reasonably safe (and yet free!) method to deal with this? Is there a way to handle through java.policy or should I sign the applet? I've never worked with signed applets...but I can certainly start reading up on the topic...Signing the applet is easier in terms of distribution. Policy change is quicker if you are just messing around or if you have a very limited distribution target.

What end users need in order to view WebHelp?

We are in the process of releasing
WebHelp. A question came up: What end users need in order to view WebHelp?
Any advice?
Thank you,
lisa

Hi Lisa
Basically they need a web browser and access to the WebHelp. Preferably Internet Explorer or Firefox and whatever the browser, recent versions of each. And if you have any Flash content in your help (such as Captivate movies) the browser needs a recent version of the Flash Plug In or Helper object.
I believe Google Chrome is not a supported browser and you might see issues with other browsers than IE or FF.
Cheers... Rick

HELP!!!!! Double Applet Viewer

I am running an applet in JBuider. When I run it JBuilder's applet viewer one applet comes up but when I run it in Sun's applet viewer 2 applet viewers come up. An ideas on why this is happening and how I can fix it?

Check your HTML file to see how many applet tags it has.

Writing an Applet Viewer?

I'm not sure why I'm interested in writing an applet viewer, I just thought it would be a nice project. Anyways, I'm wondering if anyone knows on how to tackle this. I've tried a little experimenting but everytime I call the applet init() method from my c++ program, it always crashes. I've tried to debug the problem in a external debugger but I can't seem to know why it's happening. If anyone can help direct me such as what I'll need to learn, what steps I need to take, etc, that'll be excellent. Thanks for your time.

Crashes mean pointer problems.
Are you verifying every single JNI call with error checking as appropriate?
