Sign your applet, or use web start.

How to use Java WebStart with EJB ?

hi forum...
how to use Java WebStart with EJB ? examples ?

hi forum...
how to use Java WebStart with EJB ? examples ?Well, for starters these are complementing, not 'cooperating', technologies. I presume, since EJB's do not - directly, at least - communicate with a web browser, that you intend for "Java WebStart" to somehow invoke an EJB?? Java WebStart is a technology for running client-side (Java) applications from the web browser - perceptively, the application resides on the server, but technically it, like an applet, is downloaded to the client and run there. Unlike an applet, however, it is not constrained by "sandbox" restrictions and does not have to be re-downloaded each time it is invoked - though the process allows for automagically updating the client-side with new versions of the application. ;) So, with this in mind, to "use Java WebStart with EJB" means little more than deploying an EJB client application with Java WebStart as the distribution channel.

How to use JNI in an Applet?

Can a native method can be invoken in an Applet?If it can,which knowledge of Java should be used and how to use it?

You could I suppose if yo sign the applet (which, if the user accepts it, will allow it to use features otherwise not available to an applet because of the secure sandbox). However, I am not sure how you would deploy the necessary native library since it must be available to the native OS loader (ie, a file on the client machine). If you are deploying the applets (see WebStart perhaps) you could do it.
But generally it is a poor idea to try to use JNI in an Applet, and this is probably something that you would not want to use outside of an intranet environment.

now I'm not sure how to zip the dlls so that it can be used in nativelib?and how to used the <nativelib> label? just add it in the jnlp file ok?
Thanks.

>
Thanks,Andrew!>Your detailed and technically specific reply is all the thanks I need ( and probably more than I deserve ;).
I am still mulling (thinking) over your reply, there is nothing that 'jumps out at me' as being wrong with the way it is done, it all is looking like it 'should' work. The only other thing I can think to check is "did JaNeLA report any problems with it?"
Oh hang on, wait just a second..
If this webstart app. uses a native lib, it must declare security 'all-permissions'. See below for a 'hand written' variation to your posted JNLP file. Please make sure you validate these edits, since I did not (and I'm a little drunk, at this moment!).

Mindu,
WebStart will work with EJB. I use it with WebLogic Server. You have to make sure and deploy the weblogic.jar file - sign it if needed.

From Forms Product Management - Using WebStart with Forms

I noticed a number of posts on this forum asking if you can run Forms as an application (using WebStart) rather than an applet in a browser.
I would be interested to know the reasons why people want to do this. Is it so that there is no browser windows? Is it because it has more of a "desktop feel"...
I would be interested to hear any of your reasons.
Thanks in advance

I don't think you'll get too many replies. I expect most people here are either committed to using Web Forms already (and so don't need this functionality) or else are still in client-server mode (and so don't understand what you asking).
We are just in the process of migrating from Forms4.5 to 9i (I'm in the WebUtil beta) and we are still finding out all sorts of non-obvious things about web-deployment - don't get me started on how awful the whole GIF thing is! So I'm not really qualified to have an opinion about Webstart. I only have the vaguest idea what it does and I'm not sure I want to read up about it just so I can tell you whether to go ahead with it.
What I will say is this:
(1) Anything that makes 9i Forms more like a client-server experience for the users would be a good thing, bceause it would minimise the shock of transition.
(2) Choice is a good thing. Your recent experience of developers' spleen over the removal of client-server should tell you that people respond well to being given options and badly to having them removed.
(3) If I've correctly understood Haris Peco in their second point we could get rid of O9iAS and that would be flipping marvellous for everybody (except possibly the VP in charge of O9iAS Sales :P).
My tuppence ha'penny worth.

Learning how to use Layout Managers

The code that is included in this post is public code from the SUN tutorials. I am trying to learn how to use the layouts and add individual programs that were created to each component in the layouts.
This is what I am exploring:
I want to have a tabbed layout like the example TabbedPaneDemo located at http://java.sun.com/docs/books/tutorial/uiswing/examples/components/index.html#TabbedPaneDemo. Below is the code.
In one of the tabs, I want to place a button and report in it. When the button is clicked, I want the report refreshed. Eventually I will be populating an array with data. The report I want to use the example SimpleTableDemo located at http://java.sun.com/docs/books/tutorial/uiswing/examples/components/SimpleTableDemoProject/src/components/SimpleTableDemo.java. Below is the code.
From what I have learned, you can place a container inside a container. So I should be able to place the SimpleTableDemo inside the tab 4 of the TabbedPaneDemo.
If this is indeed correct, then how do I put these two things together? I am getting a little lost in all the code.
Any assistance in helping me learn how to create and use layout managers would be appreciated.

Before I did what you suggested, which I appreciate your input, I wanted to run the code first.
I tried to run the SimpleTableDemo and received the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: SimpleTableDemo (wrong name: componets/SimpleTableDemo)
at java.lang.ClassLoader.defineClass1(Native Method)
at java.security.SecureClassLoader.defineClass(Unknown Source)
at java.net.URLClassLoader...
there are several more lines but as I was typing them out I thought that maybe the code is not written to run it in the command window. The errors seem to be around the ClassLoader. Is that correct? On the SUN example page when you launch the program a Java Web Start runs. So does this mean that the code is designed to only run in WebStart?

Can't figure out how to use home sharing

Since the latest couple iTunes updates, my family and I can not figure out how to use home sharing. Everyone in our household has their own iTunes, and for a long time we would just share our music through home sharing. But with the updates, so much has changed that we can no longer figure out how to use it.
I have a lot of purchased albums on another laptop in the house, that im trying to move it all over to my own iTunes, and I have spent a long time searching the internet, and everything. And I just can't figure out how to do it. So.... how does it work now? I would really like to get these albums from my moms iTunes, onto mine. I would hate to have to buy them all over again.
If anyone is able to help me out here, that would be great! Thanks!

The problem im having is that after I am in another library through home sharing, I can't figure out how to select an album and import it to my library. They used to have it set up so that you just highlight all of the songs you want, and then all you had to do was click import. Now I don't even see an import button, or anything else like it. So im lost... I don't know if it's something im doing wrong, or if our home sharing system just isn't working properly.
Thanks for the help.

How to use the same POWL query for multiple users

Hello,
I have defined a POWL query which executes properly. But if I map the same POWL query to 2 portal users and the 2 portal users try to access the same page simultaneously then it gives an error message to one of the users that
"Query 'ABC' is already open in another session."
where 'ABC' is the query name.
Can you please tell me how to use the same POWL query for multiple users ?
A fast reply would be highly appreciated.
Thanks and Regards,
Sandhya

Batch processing usually involves using actions you have recorded. In Action you can insert Path that can be used during processing documents. Path have some size so you may want to only process document that have the same size. Look in the Actions Palette fly-out menu for insert path. It inserts|records the current document work path into the action being worked on and when the action is played it inserts the path into the document as the current work path..

How to use airport time capsule with multiple computers?

I'm sure there are some thread about this but i couldn't find it... so sorry for that but hear me out! =)
I bought the AirPort Time Capsule to back up my MBP
And so i did.
then i thought "let give this one a fresh start" so i erased all of it with the disk utility and re-installed the MBP from the recovery disk.
I dont want all of the stuff i backed up just a few files and some pictures so i brought that back.. so far so good.
Now i want to do a new back up of my MBP so i open time machine settings, pick the drive on the time capsule and then "Choose" i wait for the beck up to begin, and then it fails. It says (sorry for my bad english, im swedish haha) "the mount /Volume/Data-1/StiflersMBP.sparsebundle is already in use for back up.
this is what i want:
i want the "StiflersMBP.sparsebundle" to just be so i can get some stuf when i need them. it's never to be erased.
i want to make a new back up of my MBP as if it's a second computer...
so guys and girls, what is the easiest and best solution?
Best regards!

We will pass the seperator to the WRITE_FIELD_SEPARATOR parameter as
CALL FUNCTION 'GUI_DOWNLOAD'
EXPORTING
filename = v_file
write_field_separator = '|'
TABLES
data_tab = itab[] . "Our internal talbe filled with data
Re: Why Function GUI_DOWNLOAD can create XML file but not a flat file?
Award points if useful
Thanks,
Ravee...
