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.

How do I add multiple images into one file?

I'm sure this is something that's been covered in another post (or even in the help portal) but I think my wording in my search terms are not correct or... I don't know, because I just can't find what I'm looking for.
I want to know how to add multiple images into one file/one image, both horizontally and/or vertically. To give you an idea of what I mean, check out :
http://www.best10apps.com/apps/comic-story,531596060.html
If you scroll down, you'll see a heading entitled : Screenshots of Comic Story. Notice how there's 3 pictures (divided by borders). 2 of those pictures are side by side, and 1 of them is below the first 2 pictures.
I want to know how to add different pictures/images and put them into one picture.

One way is to create template PSD files and populate them with your images using Photoshops scripts.
Photo Collage Toolkit UPDATED June 12, added Picture Package Support via PasteImageRoll and BatchPicturePackage scripts.
The package includes four simple rules to follow when making Photo Collage Template PSD files so they will be compatible with my Photoshop scripts.
There are eleven scripts in this package they provide the following functions:
TestCollageTemplate.jsx - Used to test a Photo Collage Template while you are making it with Photoshop.
CollageTemplateBuilder.jsx - Can build Templates compatible with this toolkit's scripts.
LayerToAlphaChan.jsx - Used to convert a Prototype Image Layer stack into a template document.
InteractivePopulateCollage.jsx - Used to interactively populate Any Photo Collage template. Offers most user control inserting pictures and text.
ReplaceCollageImage.jsx - use to replace a populated collage image Smart Object layer with an other image correctly resized and positioned.
ChangeTextSize.jsx - This script can be used to change Image stamps text size when the size used by the populating did not work well.
PopulateCollageTemplate.jsx - Used to Automatically populate a Photo Collage template and leave the populated copy open in Photoshop.
BatchOneImageCollage.jsx - Used to Automatically Batch Populate Collage templates that only have one image inserted. The Collage or Image may be stamped with text.
BatchMultiImageCollage.jsx - Used to Automatically Batch Populate Any Photo Collage template with images in a source image folder. Easier to use than the interactive script. Saved collages can be tweaked.
BatchPicturePackage.jsx - Used to Automatically Batch Populate Any Photo Collage template with an image in a source image folder
PasteImageRoll.jsx - Paste Images into a document to be print on roll paper.

How do you add multiple birthdays to one contact

I keep searching but it seems all the tips are old form previous versions or I am missing something. I am currently using Mac OS X 10.7.3
I am trying to add multiple birthdays in my Address Book under one person, thier family members and I want it to sync with iCal. I also did not see the Anniversary option in Address Book
Please help,
Thank you,

This has two parts. The second one, having the extra dates sync with iCal/Calendar, I don't (yet) know how.
The first one, though, isn't so hard. Go to Addressbook/Contacts preferences. Under templates, click on "Add field" and select "dates."
Now you can customize the template to default with "Anniversary" or whatever other nametag you'd like to give the date field or fields.
I'd really like to hear how, if it's at all possible, even, to have those sync in iCal/Calendar.

How do I add multiple emails for one contact to the same group list?

When trying to set up a group email list using address book, is there a way to include multiple emails for the same contact to one group. For example I'm trying to set up a baseball team group email. Some kids want emails sent to both mom and dad which have different emails. I currently have them in my address book as the boy's name with the emails listed as mom and dad. I can add one "mom" to the list but when I compose the email, it will use the most recent email used. I would like the group to contain both addresses for mom and dad without setting up to different contacts for the same player.

var cToAddr = this.getField("saManager").value + ";" + this.getField("ManagerEmail").value;

How do i add multiple people in one pod cast

me and my friends are trying to make some pod cast for my youtube channel. the problem is not all of us can get together to make it. i wanted to know how we can all be in the pod cast at the sametime?

Skype works really well - if the person initiating the call does not have anything else running on their computer and they have a good internet connection.
Here is the setup I have used for recording skype calls for the past 8+ years for my podcast.

You can use any good digital recorder in place of the iRiver shown - I actually now use a Marantz PMD-660 - which is definitely a little overkill.

How do I add multiple songs to an existing playlist from the (no longer called) Library? Highlighting multiple songs and clicking the "Add to" button will only add the with the little arrow, not all the highlighted ones!

How do I add multiple songs to an existing playlist from the (no longer called) Library? Highlighting multiple songs and clicking the "Add to" button will only add the one with the little arrow, not all the highlighted ones! I am using the "new" iTunes.

For the moment there isn't a way for us end-users to control what is "matched" or "uploaded." That is purely a result of Apple's server-side algorithms.
To re-add multiple songs at once simply highlight all the songs you want to re-add, then right-click (or Control+click) the list and choose "add to iCloud."

How do you add multiple iTunes to Keynote

How do you add multiple songs from the iTunes to your Keynote presentation?

Jer&Renee,
welcome to Apple Discussions.
It depends where you want them in your presentation.
Open the Media inspector and choose a playlist. In the list of entries, mark those you want to add to Keynote (use command-click to mark multiple titles not in one block).
Then drag the marked titles either on a slide or on the small Audio field (looks like a frame) in Document inspector. When you then hover the cursor at the Audio "frame", you'll see the quick info "Multiple Files". You cannot change the order or remove one of the files, but only all of them.

How do I add multiple addresses/contacts in an email tread to my contact list without having to enter each at a time?

How do I add multiple addresses/contacts in an email tread to my contact list without having to enter each at a time? I have AppleScript but don't see "add address" in any of the boxes/drop-downs.

Sorry, but Address Book does not allow you to select more than one email address to send to in a group. There's really no reason why people need multiple copies of a message, anyway; they have the option of forwarding email to another email address of theirs.
