Portal Server allows multiple sources of information, applications, and services to be displayed within a single page or set of pages that the user can view in a browser. The page in which the content is included is known as the desktop. The various sources of content are displayed in rectangular areas arranged in rows and columns within the desktop called channels. A Java class, called a provider, is responsible for converting the content in a file, or the output of an application or service into the proper format for a channel. A number of providers are shipped with the Portal Server including a bookmark provider, an application provider, and a notes provider. As the desktop is imaged, each provider is queried in turn for the content of its associated channel.

How to get UCM content from Java class?

Hello,
I need to get UCM content from backend I mean from the Java class. Is there any way to do that? If anybody please give any resources it will be very helpful.
Thanks and regards.

Hi
You mean to say that with JAVA API you want to search and retrieve the contents ? If yes , then you should use RIDC API for the same and that way you can use to do all the operations on UCM from the JAVA Api .
Search this forum and you will get sample codes for the checkin , search , checkout operations .
Documentation is available at : http://docs.oracle.com/cd/E14571_01/doc.1111/e16819/toc.htm

Creating Web Service from Java Class-How to eliminate nillable="true"

Does anyone know how to eliminate the attribute, nillable="true", from the element tags which describe the parameters in the WSDL created when creating a web service from a Java Class? It does this only for the string types. Is there something I need to set when creating the web service or before creating the web service? Or the only way is to modify this WSDL then recreate the web service from the WSDL.
example part of wsdl:
this is in the <types> tag:
<complexType name="getData">
<sequence>
<element name="schema" type="string" nillable="true"/>
<element name="table_or_view_name" type="string" nillable="true"/>
</sequence>
</complexType>
<complexType name="getDataResponse">
<sequence>
<element name="result" type="string" nillable="true"/>
</sequence>
</complexType>

I did do this and I got the following error when deploying to the Stand-alone OC4j:
Operation failed with error:
Error compiling

Impl class Method: getData declares exceptions not declared by the interface (java.lang.Exception)
I am quite sure what it is saying. It generated the code for the Interface: dbdatapackage.DVDataWS. Impl class. Why would it not do it right? What expection is it complaining about? java.lang.Exception?

WSDL generated from java class - how to include headers?

I am using the servicegen ant task and generating a web service based on a java class. I would like to include a username and password in the soap header and read that info using a handler. I am able to get that working, but how do I get the auto-generated WSDL to include the username/password header information? Is there something that I have to do in the handler so that this information is included in the WSDL?
Thanks,
Mike

Ant or what tool to compile Java Classes

For the past year I have been using Windows command window to compile Java Classes for my Servlets, Java Beans and Helper classes. I use Cold Fusion studio as my IDE for creating the Java classes. All of my Web Applications use MVC for Forms feeding small databases and I only have around 7 to 10 class files per Web application.
Should I start to use Ant and/or what is recommended so I can keep up with current technology instead of using Windows Command Window to compile my Java classes?

Try the following link.
https://www.sdn.sap.com/irj/sdn/downloaditem?rid=/library/uuid/cfc19866-0401-0010-35b2-dc8158247fb6
The download in the above link has NWDS and portal as well. Unzip the file and install NWDS studio.

Java Application [Java Bundler]: how I can use an image? Which path?

Hi,
how I can use an image in my Java Application when I create the jar bundle with Jar Bundler? Which is the path of the file? I don't know if I got it across...

By image, do you mean an icon for your program?
If so, then you need to create the image you want using any graphical drawing program, then use a utility such as Img2icns to put the image into the correct format (.icns). Once you have this, you can drag it into Jar Bundler and IIRC it just works.

Trying to invoke a Java class from BPEL Proces using Java Embedding

Hi All,
I have a requirement to invoke a Java class from the BPEL process;
I am trying to import the class by "* <bpelx:exec import="+package_name.classname+"/>*.
But, while compiling, I get the following error:
"Error(19,57): Failed to compile bpel generated classes. failure to compile the generated BPEL classes for BPEL process "BPEL_PROCESS_NAME" of composite "default/COMPOSITE_NAME!1.0"
The class path setting is incorrect. Ensure that the class path is set correctly. If this happens on the server side, verify that the custom classes or jars which this BPEL process is depending on are deployed correctly. Also verify that the run time is using the same release/version."

What is an .acv file and how do you use it in PS?

I downloaded a PDF about using curve adjustments to compensate for evaluating prints under 3500K SoLux halogen lighting relative to using a monitor calibrated to 5000K for editing. (by John Paul Caponigro). Along with the download came a file named "correctforhalogen.acv" but there is no mention of it in the PDF.
I know this file has something to do with doing a quick curves adjustment for color correction, but it doesn't appear to be an actions file. Does anyone know what .acv files are exactly and how you implement them in PS? Thanks.

Thanks Wade.
That did the trick, once I figured out the missing step. For other folks interested, to use an .acv file to adjust a curve:
Open the Curves Adjustment Panel > Panel Options drop-down menu > Load Curves Preset... > find & select the .acv file (on hard drive) in the "LOAD" window > click LOAD. The adjustment in the .acv file will be applied to the image and appear in the curves graph of the Curves Adjustment Panel. Slick.
Apparently, moving the .acv file to the "Curves" folder in the "Presets" folder allows this curve adjustment to be a permanent preset choice. It can then be found under the Curves Panel preset drop-down menu. Just look for the original .acv file's name in the list.

What is a smart address and how do I use this function.

I am trying to find out how to add the name of a sender to my address book. Mail help says
" In a message you receive, click the arrow in a Smart Address and choose "Add to Address Book" from the pop-up menu. Or select a message in the message window and choose Message > Add Sender to Address Book."
Well, there isn't a Smart Address or any arrow to click. When I try to look up Smart Address in Mail help it tells me TopicListNoResults....!!
So what is this feature and how do I use it.?!
Message was edited by: 12frets56

Look in the preview window at a message you have received and put the cursor over the From address. The name will be surrounded by a blue oval with a down arrow on the right end. Click the arrow and one of the options is add to address book.

What is the luma key and how is it used in PE4?

How do I used this effect?
Thank you

Are you talking about the setting on the track matte?
The alpha setting bases transparency on the whiteness of the selected layer.
The luma setting bases transparency on the red, green and blue brightness of the selected layer.
It's easier to demonstrate that explain. I suggest you experiment, using multi-colored clip to create your track matte.

RFC lookup with java proxy class, how do I use "fromXml()"?

Hi,
I'm trying to do an RFC lookup in XI using java proxy classes (SAP Enterprise Connector).
The XMLPayload comes from a java proxy class which has been converted to xml using a method called
.fromXml() for this. I just don't know how to use and I can't find any documentation for it.
Would very much appreciate if someone could provide me with an example of how to use this class

Hello Fred,
unfortunately it does not work, maybe I can be more specific about what I'm trying to get. I'm following Josh Smith's article on CodeProject related to WFP TreeView
Josh Smith article. He has Class named Person with the following structure
public class Person
readonly List<Person> _children = new List<Person>();
public List<Person> Children
get
return _children;
public string Name { get; set; }
The same is populated from Database class using method named GetFamilyTree() which look as follows:
public static Person GetFamilyTree()
// In a real app this method would access a database.
return new Person
Name = "David Weatherbeam",
Children =
new Person
Name="Alberto Weatherbeam",
Children=
new Person
Name="Zena Hairmonger",
Children=
new Person
Name="Sarah Applifunk",
new Person
Name="Jenny van Machoqueen",
Children=
new Person
Name="Nick van Machoqueen",
new Person
Name="Matilda Porcupinicus",
new Person
Name="Bronco van Machoqueen",
new Person
Name="Komrade Winkleford",
Children=
new Person
Name="Maurice Winkleford",
Children=
new Person
Name="Divinity W. Llamafoot",
new Person
Name="Komrade Winkleford, Jr.",
Children=
new Person
Name="Saratoga Z. Crankentoe",
new Person
Name="Excaliber Winkleford",
I'm trying to figure out how should I write
GetFamilyTree() method using Entity Framework in order to connect to my SQL Server database and populate this Person class as it was populated manually in Joshs Example. The table I'm using in SQL Server is described in
my first post named Employees (it's self reference table)

Hi everyone!
I tried to update a few apps from my iPhone, and to install new applications from APPSTORE. But i got a message :" Your Apple ID has been disabled"!!!!!!
What can i do now? Can you help me please?
The same thing happend with my IPAD....
How can i do to function all this in the same way which was working till this problem appears.
I want to mention that i have 2 email adresses asociated with the same Apple ID.
wait for an feedback!
Thanks a lot!

Depending on why it's been disabled you might be able to re-enable it via this page : http://appleid.apple.com, then 'reset your password'
Or you might need to contact Apple : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page
If it then works on your computer's iTunes but not your phone/iPad then try logging out of your account on the phone/iPad by tapping on your id in Settings > Store (Settings > iTunes & App Stores on iOS 6) and then log back in and see if that 'refreshes' the account on it
