Distributing javahelp with an app

Hi
I have an application which uses JavaHelp and this works great on my development workstation. I wanted to distribute my app at this point and wondered if anyone could tell me what i'm missing to get the JavaHelp system working on another machine. I haven't packaged anything separately, it is all within one jar file (helpset.hs, map.jhm, toc.xml etc). When I try to run my app on any other machine so far, i get the error message:
"java.lang.NoClassDefFoundError: javax/help/HelpBroker."
What do I need to package with my app so that the target machine can run my app and the javahelp system? Do I need to package the jh.jar along with it?
Please help.
Thanks!

never mind I solved it.

Best practice when using Tangosol with an app server

Hi,
I'm wondering what is the best practice when using Tangosol with an app server (Websphere 6.1 in this case). I've been able to set it up using the resource adapter, tried using distributed transactions and it appears to work as expected - I've also been able to see cache data from another app server instance.
However, it appears that cache data vanishes after a while. I've not yet been able to put my finger on when, but garbage collection is a possibility I've come to suspect.
Data in the cache survives the removal of the EJB, but somewhere later down the line it appear to vanish. I'm not aware of any expiry settings for the cache that would explain this (to the best of my understanding the default is "no expiry"), so GC came to mind. Would this be the explanation?
If that would be the explanation, what would be a better way to keep the cache from being subject to GC - to have a "startup class" in the app server that holds on to the cache object, or would there be other ways? Currently the EJB calls getCacheAdapter, so I guess Bad Things may happen when the EJB is removed...
Best regards,

Hi Gene,
I found the configuration file embedded in coherence.jar. Am I supposed to replace it and re-package coherence.jar?
If I put it elsewhere (in the "classpath") - is there a way I can be sure that it has been found by Coherence (like a message in the standard output stream)? My experience with Websphere is that "classpath" is a rather ...vague concept, we use the J2CA adapter which most probably has a different class loader than the EAR that contains the EJB, and I would rather avoid to do a lot of trial/error corrections to a file just to find that it's not actually been used.
Anyway, at this stage my tests are still focused on distributed transactions/2PC/commit/rollback/recovery, and we're nowhere near 10,000 objects. As a matter of fact, we haven't had more than 1024 objects in these app servers. In the typical scenario where I've seen objects "fade away", there has been only one or two objects in the test data. And they both disappear...
Still confused,

Simple java download bundled with my app -- what link can I use

I have a java app that I'd like to make as easy as possible for people to install and use who don't know about java or don't want to deal with installing a JRE. I built two different setup files, one bundled with a private jre for the app and one that just has the app.
If the user downloads the non-jre-bundled version, and they either don't have a jre or they have a version that's not supported by the app, my insatller will detect this and abort the install with instructions to download a jre or download the bundled verison of the app.
I'd prefer to ask the user's permission to download a private jre automatically in the above scenario. I know how to do this with my installer enviropnment (NSIS), but I can't find a suitable url from Sun that serves this purpose. I need a link that bypasses the licence agreement page and just directly downloads the jre.
I got a url from a sample NSIS script that seems to provide this, but the most recent file is dated June 2005 and points to JRE 5 Update 1.
The root url is http://dlc.sun.com/jdk/
From there you can see several jre/jdk links for 1.4 and 1.5, but no 1.5 jre or jdk with anything beyond update 1.
Does anyone know of a link I could use to directly download the latest jre 1.5?

If any such site exists, it is in violation of Sun's
current Java license.I'm not a lawyer, but the JRE License Agreement seems to be written in English, so I took a look at it. Paragraph B of the Supplemental License Terms (near the end of the license) would seem to apply, and I've pasted it below.
As I read it, I think you're right that a direct download site is in violation of the agreement. This seems to be the case because item (v) requires anyone distributing Sun's JRE to pass on the license terms. By definition a direct download site doesn't do that.
Having said that, it seems that the site I pointed out in the original post is a Sun site. Apparently they're willing to violate their own license terms. I just wish they'd update the site, so something beyond Update 1 were available for JRE 5.
This is the first time I've ever heard this. I've
seen many people on this forum getting help bundling
the JRE with their app. Note that the Sun license agreement does not preclude bundling the JRE with you app, so long as you obey the stated restrictions.

Distributed programming with HTML DB?

Hi!
Has anyone done any distributed programming with HTML DB? If so, are there any crucial factors to be taken into account?
I thought of extracting the original application, importing it into my DB, changing and creating pages, exporting the single pages and re-importing them into the original application.
I suspect that creating new pages will cause trouble, but what about changing existing ones? Can they be overwritten without any problems?
Thanks for sharing your experiences!
Sabine

Sabine,
Do you want to make changes to you application only on a development machine then update production?
If so then you can make a new version of the application and simply import the entire application back into production. My personal preference is to pick a new application id for the updated application when I re-import. That way my current production app is sitting there unchanged. I then point users to the new version and update the proprieties of the old one to stop users running it (with a message to log into the new application) It also allows me to back out easily if there are problems.

Best way to bundle JavaHelp with application

What is the best way to bundle JavaHelp with an application....
At present I have to run the application that uses JavaHelp as follows
java -classpath ;lib/jhall.jar HelpMenu
Is there a better way? so that when the application is moved to a client machine the classpath to the javaHelp jhall.jar does not have to be supplied as above?
Cheers :)

If you don't want to specify the classpath you can
1> either create a batch/shell script with lauches the app with the appropriate classpath
2> You jar your app and specify the classpath in your jars's MANIFEST.MF file like this.
Main-Class: main class name which will launch the app
Class-Path: jhall.jar
The above entries assume jhall.jar is in the same dir as your main jar. You can put more jars in the classpath above by separating them with space.
With this the app can be just lauched by typing: java -jar filaname.jar

How do I distribute Pages with Apple Configurator?

In my school we have 15 iPads and I want to install Pages, Keynote, Numbers onto them with Apple Configurator. When viewing the ipad apps in the App Store on my iMac, it doesn't show them as free, but it does if I view them on the app store on an iPad. I purchased the free apps on an iPad so it linked them to my account, and I was then able to download it to my iMac. However, when I try and distribute them using Apple Configurator, it's asking for redemption codes. I can install them fine individually on each iPad, but they're around 1GB in total to download, I'd rather only have to do this once and send them to all iPads rather than downloading it 15 times.
Thanks.

I came across this problem again the other day when I download an app that was free for a limited time.
I've started using Apple Configurator purely for iOS updates and installing a profile containing Wi-Fi settings etc. I have been using iTunes to manage apps which is a lot more powerful. After downloading the apps thtrough iTunes onto my Mac, I can then distribute all of the apps to the iPads via USB (the iPad's are stored in a Griffin small cabinet that acts as as USB hub) and I can manage them all at once. It takes a while to transfer, but its quicker than downloading 5+GB on each iPad, and iTunes allows you to manage app folders as well.

If you have a 1G iPod you can update to as far as 3.1.3. Yu get hat paid update here:

You can identofy your iPod here:

What iOS is curently on your iPod (Setting>Genral>About>Version) you need as lest 2.0 for apps but most apps need 3.0 or later.

Problems with n97 apps connecting to network (Voda...

Problems with n97 apps connecting to network (Vodafone UK – 3G)
Recently a number of my apps which used to connect automatically to the internet (which ever was available – known wi-fi or 3g) have stopped doing this. They now only connect to one known wi-fi.
I’ve tried uninstalling and reinstalling each app, but this hasn’t solved the problem. I’ve checked for software updates and do not believe any have been applied or are available. All apps have been downloaded via Ovi on the phone. I still am able to access the internet by the web browser which was installed on the phone and via google maps (which also still manages GPS position, search, etc).
The apps which I notice causing a problem are:
Sainsbury’s/nectar
Tesco
Map my tracks
Snaptu
Opera Mini
Any one got any ideas???

I have the same problem since i updated my mac to 10.5.6.
Each time I have to do a diagnostic and retype the WEP password to have the internet connection.

Problems with Remote App on iOS 4?

I have a new iPhone 4 and tried to use the Remote App in Connection with Apple TV. While I'am able to pair the remote app with Apple TV, I cannot use it properly. It works for a while, then it get's disconnected with a message that maybe a Firewall might be activated in the Router.
I have no problems with Remote App connected to my iTunes Library. I also tried it with a iPod Touch which is still on iOS 3.1.3, no problems to connect to the Apple TV from there as well.
Are there any known problems with iOS 4 and Apple TV?

May I ask what wifi hardware you use? It might be an wifi issue, but one which is only related with the "Bonjour" protocol which seems to be used for the Remote App. I found this thread which is older (iOS 3) but describing exactly the same problems:
http://discussions.apple.com/thread.jspa?threadID=2048555&start=0&tstart=0
bear in mind that the iphone4 is now "n" wifi compatible (2.4Ghz), so could it be that the "n" part of your network is poor and thus why you only see the problem on the iphone4 ?
At least it is not poor when using it from other devices or moving a lot of data in other Apps. It is all Apple Hardware (nothing older than 2 years), and maybe that's the problem. I never had network hardware which made so much trouble, as Apples Airport series. I wouldn't wonder if it is an incompatibility between a new wifi chip in the iPhone 4 and a older Revision of an Airport device. But I don't know how to check - is there a system.log on the iPhone which I can access somehow?

Issue with the App Store showing up blank.

Issue with the App Store, it will not let me search for new apps. The screen is blank. The update section and features section works, but it will not let me search for new apps. I have restarted my phone and no changes. The newest update to the iphones when the iphone 5 came out, i think, messed up this app. When i am looking at how to fix it, it tells me to delete it and try again, but the App store is not a deletable app. Any ideas why my App store, specifically the search section of this app doesn't work?

I suspect it is on Apple's side of things. Mine was blank too, but now it works again. Fixed itself one morning.

When i go to sync my apps with my computer it tells me ''are you sure you want to sync apps ? all exsisting apps and there data on (iphone) will be replaced with the apps on this itunes library'' does this mean all my data will be lost if i continue ?

Regarding your broken, previously authorized computer, here's how that works:
You would authorize your new computer -- maybe you've done that already. Then you will have two computers authorized. Apple allows you to have up to five computers authorized at any time. If you get to five, you can then go to your account details in iTunes and remove all authorizations.
Bear in mind this is not saying you can synch to more tham one library. Razmee209 and gdgmacguy's comments above are correct. But if Apple only allowed you to authorize one computer at a time, then having a broken computer would mean you could no longer use your Apple ID with iTunes.

Hi Grandmaz5,
If you are having issues connecting to Facebook on your iPad, and you have already troubleshot the Facebook app itself, you may want to check the built-in iOS settings for Facebook; you may find the following article helpful:

Lightning to VGA Adapter not working with certain apps

I've recently noticed that I can't watch movies on Netlix any more with my Lightning to VGA Adapter going to an LCD monitor. It works just fine with other apps just not Netflix. Apple says it is a Netflix app problem, and Netlix doesn't want to admit it's anything wrong with their app. Any one else have this problem? Is there a solution?
