Multiple struts app in one provider

I have two Struts Application, which have been converted into two PDK Portlets, as per the tutorials provider in the OTN site.
The problem is that, I want the two portlets to talk to each other.. preferably by session. But, as i noticed that, the two portlets belong to two different providers, so it is not possible to share any data between them.
Can I have two or more pdk struts portlets in one Provider.
If there is any other way to share information between two Pdk struts portlets, please tell me...
it would be of great help.
Thanks
Sam

How to create 'service' tier with functionality multiple struts apps

I am looking for some advice regarding a future project. I have 3 struts webapps (running on Tomcat 4.1.3) each with some overlapping functionality. I would like to create a 'service tier' to accommodate common functionality which can be shared between the 3 struts web apps.
What framework would best achieve this? Are EJBs the way to go? My struts apps all use DTOs so are not tied to the Action Form object. I have been looking at Spring but am not sure exactly how this will fit? Will tomcat serve my needs or do I need to migrate to something with full J2EE support. I have also considered JBOSS with Seam linking JSF to EJBs. Is this a viable option?
The service layer can be on the same machine as the struts apps although I would like to have the flexibility to move it to a separate server in the future if necessary.
I will be happy to provide more details to any who can offer me some guidance.

Hi Saish,
Thanks for your help.
I have considered both options. The main goal is to
eliminate duplicate code. However the presentation
tiers of the applications are quite different. I
will look into Martins book.
It's outstanding. One of my top five favorite books.
Would creating a jar file which is included in each
.war end up becomming a maintenance nightmare?
Depends on what you mean by ' maintenance'. In terms of onging development with your Java source, in a modern IDE, no. In terms of deployment, it does add a minor bit of complexity. However, if you are using an automated build and deployment tool such as Ant or Maven, the amount of extra work is trivial.
In your opinion what would be the advantages of
implementing the common functionality as a seperate
tier (with SPRING/EJB) vs using a JAR file and
distributing it with each app?They are not mutually exclusive. If you want to remove duplicate code, then simple refactoring is the start. As part of that refactoring, you may decide enough classes are providing similar functionality (such as transaction management, a coarse-grained public API, etc.) and create a tier. You mentioned in particular a service tier. This is a design and architectural decision. You could still completely refactor common functionality into a better design without the introduction of a new tier.
Whether to create a tier is, IMO, more art than science. Adding a tier adds complexity. However, the net effect should be to reduce system complexity. It is more 'work' to implement a true persistence tier than to simply code JDBC in model objects (or use Hibernate/JDO objects). However, as overall system complexity grows, the addition of a persistence tier adds many benefits. Business objects concern themselves solely with business logic, where as data acccess objects concern themselves with persistence. You can even have different developers with different skills specialize within a tier.
So, tiering really is a big topic. Fortunately, there are many architecture templates and design patterns to guide your decisions. "Patterns of Enterprise Architecture" (also by Fowler) compares and contrasts the more common ones. There is lively debate as to the pros and cons of different strategies. In the end, there is no cookie-cutter architecture. You will need (sometimes through the painful process of making a mistake) to see what works best for your actual system.
Finally, about remoting. Remember the first law of distributed objects, "Don't distribute your objects". There is always a performance penalty compared to an in-JVM local call. Remoting has its uses, but these should be careful architecture-level decisions. (I should concded that even this paragraph is sometimes contentious and debated).

Multiple Flex Apps on One Page

Now that I've been laid off from Adobe (along with 700 others), I would like to seek Flex consulting opportunities, and one possibility is with web designers/developers wishing to offer their clients value added components.
My question is that I heard you don't want for example three separate Flex apps on one web page, as it results in three instances of the Flash Player generated, or something like that.
So is it necessary to group multiple Flex components into one Flex app to each web page? This can limit placement of Flex components on a web page, because the web page will not be completely done in Flex, as the page must be searchable.
Any insight on this, particularly from Alex and others on the Flex product team at Adobe.
Anyone new to Flex needs help on Flex components/applications, I'm available: [email protected]
Thanks!
Greg

IMHO, it is all about memory. Lots of pages have multiple flash players running banner ads. That's because those ads are small. If you're going to stick a couple of really small flex apps on a page, I would expect most folks have enough computer resources to handle that. Once you get more complex, your apps also likely take up more screen real-state and soon you're looking at a portal and probably should have one main shell that loads sub-apps.

How do I run multiple java apps in one JVM to reduce memory use?

Hi all,
I saw an article either on the web or in a magazine not too long ago about how to "detect" if the app is already running, and if so, it hands off the new instance to the already running JVM, which then creates a thread to run the Java app in. As it turns out, my app will be used in an ASP environment, through Citrix. We may have as many as 50 to 100 users running the same app, each with their own unique user ID, but all using the same one server to run it on. Each instance eats up 25MB of memory right now. So the question is if anybody knows of a URL or an app like this that can handle the process of running the same (or even different Java) apps in one JVM as separate threads, instead of requring several instances of the JVM to run? I know this article presented a fully working example, and I believe I know enough to do it but I wanted ot use the article as a reference to make sure it is done right. I know that each app basically would use the same one "launcher" program that would on first launch "listen" to a port, as well as send a message through the port to see if an existing launcher was running. If it does, it hands off the Java app to be run to the existing luancher application and shuts down the 2nd launching app. By using this method, the JVM eats up its normal memory, but each Java app only consumes its necessary memory as well and doesn't use up more JVM instance memory.
Thanks.

How do you have multiple account apps on one device

I have an iPod touch gen 2 and it's set up on my parents computer. I want to be able to sync apps from there accounts and my account on the one device. When I do it, it asks me to authorize it on the computer. I do it and it copies the apps on to there computer. When I'm done they delete the apps from the computer. When I sync again it deletes the apps. How do I do it?

From the "iPod: Frequently Asked Questions" document found here...
http://docs.info.apple.com/article.html?artnum=60920
Question: Can I update more than one iPod with my computer?
Answer: Yes. Each iPod communicates a unique device identification number to your computer, allowing you to take advantage of automatic music transfers to your iPod even if you share a computer with another iPod user. You can choose to automatically update your entire music collection on multiple iPod players or choose to update selected playlists, allowing you to transfer custom playlists to individual iPod players.

Is it possible to deploy multiple sharepoint provider hosted apps into one azure website??

Is it possible to deploy multiple sharepoint provider hosted apps into one azure website??

I am faced with a similar requirement although the hosting environment for the provider hosted apps would be an IIS web server in our own infrastructure.
Would it be advisable to use a common IIS website to host multiple apps? The MVC web application which will provide functionality
for the apps is already in place which is why we are checking for options to use the same web project for multiple apps.
Can the web config file's clientID be shared by multiple apps?

How to have one provider with multiple portlets in JDev 11g

Hi,
I am trying to create Oracle PDK Portlets using JDeveloper 11g but for each portlet JDeveloper is creating a provider. As In JDeveloper 10.1.3.4 we can have one provider with multiple portlets in it. But JDev 11g creates provider for each portlet. How can we have one provider with multiple portlets in JDev 11g. Is it something changed in 11g version or am I doing it wrong. As the Help says we can have multiple portlets in one provider but when creating portlets it does not do that. Any help is appreciated.
Thanks

Command+Q does the same thing for Mac. Just keep hitting that key combo untill all are closed.

Multiple FCPX licenses on one app store account

Hi all,
I am trying to figure out if it's possible to run multiple FCPX licenses on one appstore account.
Searching the web gave me multiple options, but none of them really answered my question.
It's only two licenses (for two machines) so we aren't capable of volume licensing since that's only availabe when running more than 20 machines.
anyone an idea? would be great!
Thanks in advance

I'v got the same problem.
According to FCPX license one licens can be usen on one computer in the same time.
If You need to run in the same time more then one instance You need more license.
I bought one and i need three more.
Apple support in poland sending me to 'mac app store support form' on apple site... but this support sending me to Apple support in poland with this problem.
As far, for Poland there is no edication licenses and we need (i'm working at university) to but the same number of FCPX licenses like the number of computer on which we want to use them during classes... but mac app store aplication don't have button which allows me tu buy anoyher licenses... it claim that i got one olready....
If any one know how to buy another licenses on the same ID tell us.

How do I add multiple portlets to one provider?

Hello,
I'm using JDeveloper 10g. Created an Application Workspace which holds several projects (java/jsp porlets). I would like all of these portlets to be under one provider rather than registering a provider for each project. Do I choose one project and add information to the provider.xml file for my other portlets? If anyone could help, it would be appreciated...
TIA

[Matthew: think I understand. Is it safe to use a provider for each portlet? If I had a hundred portlets would it effect system hardware requirements with multitude of providers running? Now I'm trying to determine if I should combine each project or if I should leave them seperate. Thanks again...]
Matthew - Would be good if you could hit "reply" to the last concerned post. I had some trouble trying to find whether you had posted any more questions ;-)
here's my response to your last post:
There is definitely a performance hit when you have just one portlet under one provider. First - You will have to undergo 100 provider registrations and I'm sure that can drive anybody crazy ;-)
Secondly, for each provider, there is a ProviderDefinition object created in memory. In your case, there would be 100 such objects created at any point in time (assuming 100 are in use). had you classified portlets under say 10 such providers, you will definitely save memory. For each instance of the provider registration, you have one ProviderInstance object created. So even if all these 100 providers are registered once on Portal A, you will have 100 instances of this object. When registered on portal B, 100 more will be created. This will be sufficiently less if you had just 10 top level providers.
As a best practice, you might want to group related portlets under one provider e.g. If you are having a bunch of SAP, Oracle, PeopleSoft portlets, you could create three top level providers and just add those portlets accordingly. Just an example though. the classification is totaly based on what binds two portlets together and is something that will have to be decided by you.

Merging multiple apps into one app (or instance)

Basically, i'm trying to create a 'social' app that combines the apps I use for Twitter, Facebook, Instagram and the default iMessages app.
At the moment I've just made an app in Automator that just launches all the separate apps at once, and have them set out in a comfortable window configuration so I can see/access everything.
Is there a way to somehow combine all these apps into one standalone app or one single instance? Just so I can have one little icon in the dock that manages all the apps (so I can open/quit them all at once just by using the one icon), and so it doesn't take up space on the dock when all the apps open.
I've tried things like editing the .plist file in apps to hide their icon, but it causes most of the apps to function incorrectly. Also, as a temporary way to exit all the apps at once, I created another Automater app that closes them all simultaneously, but it's still not quite what I'm after!
Hope that makes sense! Any help would be appreciated.

One App to rule them, One App to find them
One App to launch them all and in the dock combine them...
Uh. Yeah.
What you want, if I'm understanding you, is an entirely new app that does the work of all the other apps. Are you sure there's not a third-party social media app somewhere that does that? It would seem like a natural development, though honestly I'm not into social media enough to appreciate whatever technical difficulties that might pose.
Barring that, you're limited. The social media apps I know about tend to focus on user interaction, which means they're not going to take kindly to efforts to hide them from the GUI, and unless they are all applescriptable getting them to work together would be torturous at best.. Even a small app that watches the other apps and tries to mediate between them would need a protracted foray into cocoa to accomplish.
But maybe I'm not understanding you. Could you give a better (more example-oriented) description of what you have in mind?

Upgrading Multiple Single App Subscriptions

I had multiple single app subscriptions for Dreamweaver and Photoshop. I upgraded the Dreamweaver one to the full Creative Cloud membership, and am wondering how or if I can cancel the remaining Photoshop single app subscription without being charged for the remainder of the years payments.
Not quite sure how it works but it's my second year subscribed to both Dreamweaver and Photoshop on the monthy plan, about 2 months into this years payments with 10 months to go. Since I'm upgrading one (paying more) I would be sad if I also had to finish this years payments for my remaining Single App Photoshop plan.

Hi Jovenator,
The option you provided is quite possible, you can cancel Illustrator subscription and then upgrade Photoshop subscription to creative cloud membership or vice versa. Also, it depends on the product version you have and upgrade options available at Adobe. Please check http://www.adobe.com/products/creativecloud/buying-guide.html for more information

How can i copy apps from one computer to another?

how can i copy apps from one computer to another?

You don't mention which operating system you have so it's difficult to provide an answer since the mac and Windows stores the files differently.
The other thing you can do is just re-download the apps from the iTunes Store. Just login to the iTunes Store on the other computer using the same Apple ID. On the right-hand side of the iTunes Store page you will see a 'Purchased' link. Clicking on that will take you to a page that will list your past purchases which you can re-download to the new computer.
