Simple example doesn't work when on two machines

I have a simple RMI example that works when I run both the client piece and the server piece on one machine. However, when I seperate them to two different machines, it does not work. The client piece just sits and waits at this line:
Calculator c = (Calculator)Naming.lookup("rmi://162.130.1.68/CalculatorService");I believe I don't need an HTTP server running on the "server" machine, but is there anything I need to setup on either machine? Do I need to start the rmi registry from a specific folder or put the server files in a specific folder? I've heard the term "network accessible" thrown arround. Do I need to make the files "network accessible?"

The first thing I would do is what the previous poster said which refers to the term Network Accessible. The second thing I would do is remove "rmi:" in the lookup name. I've never seen that notation anywhere. The third thing I would do is make sure the rmi registry is started on the server. You can actually start it from inside the application like so: java.rmi.registry.LocateRegistry.createRegistry(java.rmi.registry.Registry.REGISTRY_PORT);
Hope I've helped. Let me know how it works out.

JSF 2.0 Beta1, simple example, doesn't work, why?

I made a simple JSF 2.0 NetBeans (Web Application project) example. Only imported library jars are jsf-api.jar and jsf-impl.jar from mojarra-2.0.0-Beta1 release.
These are files which I added:

     </h:body>
</html>And that's it. There is no faces-config.xml, as it is not needed. There are no managed beans. JSF and Facelets plugins are disabled.

... 39 moreI tried NetBeans versions: 6.5.1, 6.7-RC3 and 200906261401 Build. Tried with latest Apache-Tomcat and JBoss. It's all the same.
What is the problem? Why it seeks for a facelets com.sun.faces.config.ConfigureListener, from conventional standalone facelets library? Shouldn't it use facelets classes from JSF 2.0 library?
I tried to add facelets-1.1.15.B1 jar into project, just to see what happens, and the same exception is thrown ...
Please help!

It's because somewhere on your classpath there is a facelet-taglib.xml that's referencing Facelet 1.1.x classes which aren't present.

Simple yet doesn't work when ctrl enter to view it

I am using flash cs4 and I have two movie clips frontpage
(which is the front of a sheet of paper page 1) and backpage (which
is the back sheet of a page 1). I am trying to get frontpage to
flip over to backpage. I have 62 frames in the movie which is 32
fps. On frame 1 frontpage is alpha100% and backpage is alpha 0%. On
frame 21 I have frontpage alpha 100% and backpage 0% and frame22 I
have frontpage alpha 0% and backpage 100%. On frame 62 I have
frontpage alpha 0% and backpage alpha 100%. when I hit enter and
the movie plays through it looks good on screen, however when i
ctrl enter to publish view the movie there is a glitch. It looks
like the backpage shows up before it should and looks totaly
different when you just hit enter and watch movie.
does anyone have any suggestions as why or how to fix this
issue. I can send a .fla file if needed.

I might add that on both I used the 3d tool to rotate
frontpage to move from front to back and on backpage to rotate from
back to front.

Charger works when notebook is off, but it doesn't work when the notebook is on.

I have a HP Pavilion dv6-3070tx Entertainment Notebook PC.
My charger doesn't work when the notebook is on and plugged in, but when the notebook is off (or even when it is in sleep mode) it gets charged. I tested this by using different chargers that work in other hp notebooks. If this can be solved, I'll be grateful.

Hi
There are two structures of DVDs
• Data-DVD - as burned from DeskTop/Finder
• Video-DVD - to be played on a DVD-Player - Needs a program that can do this
One can in iMovie - Export as QuickTime .mov and save this via DeskTop/Finder onto a DVD - BUT this will only play on a Computer and if it is a Window-PC this needs to download QT-player or VLC-player.
But no DVD-player for TV can play back this.
To get a Video-DVD then You need
• iDVD (not from Apple any more) - or -
• DVD Studio Pro (not from Apple any more) - or -
• FinalCut Pro-X (can do simple Video-DVDs) - or -
• Burn - http://www.digital-digest.com/software/Burn.html - FREE - but very PLAIN - no fancy things at all.
• Roxio Toast™ 11 Pro - Fairly advanced - and costs a bit - still very Good and lot's of great tool's included. (I love it) - Can also back convert home made DVDs to an editable mode in an OK quality. With BD-component also capable to do sort of Blu-Ray DVDs.

BitmapData draw method doesn't work when the project is published as the .swf file of the web applic

Hi,
        I am totally confused by this strange error. When I tried using the draw method of BitmapData to draw a movieclip symbol of my project, it seems to work fine locally. However, as I uploaded the published .swf file to my web server and launched it as the plugin of my web application, it failed. The source codes as follows,
function printscreenClicked():void
     //ExternalInterface.call calls a javascript function to print message1
    var bd:BitmapData = new BitmapData(stage.width,stage.height);
    //ExternalInterface.call calls a javascript function to print message2
bd.draw(stage);
    //ExternalInterface.call calls a javascript function to print message3
message3 didn't show at all. Instead, the browser console shows "Uncaught Error: Error calling method on NPObject.". My understanding of this error message is that the .swf is calling something crashing, and I believe that bd.draw(stage)is the crashng method call.
Also, here is my html embed tag:
    <embed src="/tests/videoplayer.swf" id="flash" quality="high" height="510" width="990" scale="exactfit" name="squambido" align="middle" allowscriptaccess="always" allowfullscreen="true" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" style="margin: 0px auto;clear:both;position:relative;"/>
Can someone help me?

Thank you for your reply.
I tried stageWidth and stageHeight, but it still doesn't work.
The draw() methid is triggered when I clicked a screenshot button in my application as follows,
ExternalInterface.addCallback("printscreenClicked", printscreenClicked);
function printscreenClicked():void
     //ExternalInterface.call calls a javascript function to print message1
    var bd:BitmapData = new BitmapData(stage.width,stage.height);
    //ExternalInterface.call calls a javascript function to print message2
bd.draw(stage);
    //ExternalInterface.call calls a javascript function to print message3
Would you please give me an example of "waiting for Event.RESIZE is good, or just at least Event.ENTER_FRAME"?
My real purpose in this application is to capture a snapshot of a streaming video. The video is contained in a movieclip object. I tried stage first since BirmapData.draw() doesn't work when drawing the movieclip on the web site. Do you have any suggestion for this situation? Also, is there any good method to find out what happened if the browser have "Uncaught Error: Error calling method on NPObject."?

Collapse action doesn't work when several hierarchical columns in a report

Hello everyone!
I have an analysis which contains 6 hierarchical columns. And the problem is that for the 5th and 6th columns collapse doesn't work. I can easily expand the column, but I can't collapse it back. The first four columns are collapsing fine. Is there a bug which describes this?
I'm using OBIEE 11.1.1.6.7. Tried to check this issue in Mozilla and IE - collapse didn't work in neither of them.

It doesn't work here either. After checking the italicized bit below, I see that it doesn't work when called by an application either. It looks like a bug.
Here's the fix I found here. Put it in the automator action "run Applescript"
http://bbs.applescript.net/viewtopic.php?id=15292
on run {input, parameters}
--Pop Box
display dialog "Automator hosed me with a bug, so I'm making you wait for 5 secs with delicious Applescript." giving up after 5
return input
end run
The non-working solution :P
One suggestion - split the workflow into two (or more) parts.
1. Open Finder Items with Default Application
2. Ask for Confirmation
3. Run Workflow
4. Wait for User Action
5. Open Finder Items with Specific Application
Save the first as an app, the second as a workflow.

JClient query by example doesn't work in 10.1.2.

I've a JClient application I migrated from 9.0.4 to 10.1.2.
In the migrated app query by example doesn't work anymore in JTables.
Could someone help ?
Tks
Tullio

Frank, I got a testcase from Tullio. It's a 9.0.4 project uding JClient that is pre-ADF bindings.
I migrated his 9.0.4 project to 9.0.5.2 first.
In 9.0.5.2, I see already a change in behavior related to enter-query mode in the JTable, but the number of rows displayed looks correct.
Tullio, can you confirm if the problem you are seeing vis a vis enter query mode is that if you:
1. Click enter-query button
2. Click into a field like Ename and type SMITH but don't [Tab] out of that field yet
3. Click on the execute-query button
It behaves as if you've entered no criteria there.
If at step 2 above you clicked [Tab] to exit the field where you typed SMITH, then it works correctly.
Is this the enter-query-JTable-related problem you're seeing (that is, related to when you don't focus-out of the field?)
The "number-of-rows-displayed" issue you mention in this other thread (10.1.2 JClient binding Error. does reproduce with your testcase only in 10.1.2 (as well as also still having this 9.0.5.2 focus-related issue in enter query mode).

Captivate 8: audio file doesn't work when I add it to an object slide

Hi everyone,
I have problems with the audio in Captivate 8. This doesn't work when I press an object slide (button) that has an audio file incorporated. This issue doesn't happen when I add sound to an individual slide.
I have tried to fix the problem by changing the preferences, but nothing
Any suggestion is welcomed!!
Evelyn

An audio file that is attached to an object or a slide, will play when that object or slide become visible. I don't know what you mean by 'has an audio file incorporated'? Do you mean that it is attached to the button in its audio part of the Properties, which is in the Options tab? In that case the audio will just play when that button gets visible, if it is at the start of a slide, audio will play at the start of that slide.
If you want an audio clip to play only when a button is clicked, you need to use an action 'Play audio', or make an audio object visible.
Audio Objects: Control them! - Captivate blog
Beware: if you do this with a simple action triggered by the button, the playhead will be released if that button has a pausing point.

My speaker doesn't work when I try to listen to music or open up a quick time file, however they seem to work perfectly when I listen to a voice memo (p.s. the volume slider disappears in a song page and even in the multi tasking bar)

my speaker doesn't work when I try to listen to music or open up a quick time file, however they seem to work perfectly when I listen to a voice memo (p.s. the volume slider disappears in a song page and even in the multi tasking bar)

Thanks for your solution, it wasn't quite what solved the problem but i remembered that i had a bit of salt water on my phone recently and spraying the charging port with an anti-oxide spray solved my problem, do you mind if i ask, how is the charging port related with the volume or/and speakers?

I have different account ID's with my iphone and computer.
I would like to standardize both to just the one.
One of the ID's doesn't work, when I tried to list this second email with the preferred one a message telling me that this email is already in use pops up.. yes it is, with me??
Is there an easy to fix this please, Fabfitz

If the email address you want to use is being used as the primary email address on a different ID you have to manage that ID and change it to a different primary email address. This explains how: Change your Apple ID - Apple Support.
If it is being used as an alternate or rescue address on a different ID, you manage the ID and either remove it or change it to a different email address. This explains how: Manage your Apple ID primary, rescue, alternate, and notification email addresses - Apple Support.

I have Adobe Acrobat 9.5.4 installed on my computer and it doesn't work when PDFing

I have Adobe Acrobat 9.5.4 installed on my computer and it doesn't work when PDFing my document using Microft Word 2010. I have tried using the tab add-in, but it doesn't respond either. The only way to convert my document is to save it as a .pdf from the save as drop down box. I need to be able to have the full functionability of creating a PDF document with the tabs and links working.
Please help!

From OFFICE 2010 you either have to have AA X or just print to the Adobe PDF printer. You give no information on your operating system or specifically what you mean by PDFing -- there are multiple ways to create a PDF from a WORD document and you have given no information. However, in this case your only choice is to print to the Adobe PDF printer. Otherwise, you need to upgrade Acrobat.

[Photoshop CC 2014] Click&hold-move-release doesn't work when adding adjustment layer from the layer panel

When selecting a menu item I used to click the left mouse button and hold it down, move the pointer to the desired menu item and release the mouse button. Everything works fine in the mine menu, but there's a problem when adding new adjustment layer from the layer panel: when I release the button nothing happens, I have to press the button again. In previous PS version it worked fine. How can I fix this?

I don't think that is user fixable, meaning you'll have to wait till adobe fixes it with an update.

It doesn't work when I press "transfer purchased items from ipod" and I don't know specidicly whitch item I need to transfer.
Whenever i press "transfer purchased items from ipod", itunes sync's for about 3 seconds, but I still can't install updates on the ipod without itues warning me about purchased items on the ipod, that aren't in the itunes library. I've tried folowing the steps in itunes help, but I can only find a step guide for when you know the specific item that needs transferring, and I donøt know that specific item.

This Apple Tech Note explains the process:
