Add new JavaBean Model

Hello Everybody,
In my Web Dynpro project I have imported a JavaBean model (including relations and
the associated helper classes). Now, I want to create a new JavaBean model in the same project and also use some of the model classes from the previous model to define the
relations belonging to the new model. I tried importing the new JavaBean model with the
same helper classes, but that is some how not possible (Error :"Model class already exists") . On the other hand, if I do not include the helper classes, the previously imported
model class are not available in the new model - so how do I define the relations?
Thanks for the feedback.

A.H.,
This is a limitation of WebDynpro JavaBean model wizard -- you may not use same JavaBean more then in one model.
The only possible but unsupported workaround is to create your *.wdmodel file manually using text/xml editor, then reload project and get new model. It's better to start with new model without same beans, then copy necessary lines from "old" model.

How to add a javabean Model to a web dynpro Project

Hi all,
I have been following the tutorial "Using EJBs in Web Dynpro Applications" for creating a customized LOCAL webdynpro application, based in javabean Model. It was made by just exporting the JAR file from a java project, as it is explained in the tutorial. OK.
The problem comes when I want to duplicate the development but using a DC Web Dynpro Project. I have re-develop every step of the tutorial but using DC projects:
DC diccionary project, DC ejb project, DC enterprise application project & DC java project.
But now I DO NOT KNOW the steps for importing the development into a model for DC Web Dynpro.
Anyhelp will be very appreciated, thanks in advance-

Thanks Jhansi,
Yes, you are right. I had already followed those steps. The error comes when I have to select between the JavaBean Source:
1. project (source folder) (checkbox)
2. public parts of used DC's (combobox)
I have been trying both, the second one by copying first the JAR called CommandBean.jar of my DC Java Project with dependencies to EJB project into the web dynpro "lib" folder, and then selecting the new entry CommandBean.jar from that combobox.
then i get de following error: "Invalid JAR - No JavaBeans available for import"
So I do not know how to use any of these two options for java source.
Thanks.

Address book model is not respected when I add new fields

Hello,
If I add new fields in the model of my adress book. AddressBook display does not comply with the specified model.
For example, after father, mother and joint, I added the following fields child 1, grand-child 1, child 2, grand-child 2, child 3, grand-child 3, child 4, grand-child 4, in order to have descendants of my friend or family.
The result is :
child 3 : Oscar
child 4 : Anatole
child 2 : Victor
child 5 : Constantin
child 1 : Aline
Please note that I entered the 5 children in the good order : Aline, Victor, Oscar, Anatole, Constantin.
An other example can be completely different with children and grand-children mixed !
To be complete, I can say that in Mac OS X 10.4 address book was running correctly, but is no longer running in 10.5 nor 10.6.7

The iPad can't be infected with a virus - by the definition of a virus being a malicious program that replicates itself across your operating system and other programs. It can be infected with malware, however that usually only happens when a user taps on a link, or actively does something.
Since the iPad can't run flash or java (?)(all or most kinds of java) then it's relatively secure.
You're probably fine.
The iPad's operating system is different enough from Mac's or PC's that even if you do tap on a virus it can't run...the malicious code is speaking a language that the iPad can't understand.

Can't add new element to model node from web service

Hi Folks,
we are using the old WebService (not adaptive one) for calling a service on XI. We are reusing the same service for loading the data and also sending them back to the backend to modify, delete or add new elements. Request and response tree structure consist basically of the same structure.
Now everything works fine so far except adding a new element to the model tree.
So what are we doing:
After calling the service for reading (and invalidate on the response), we copy the received data from response node into the request node. All the view forms are bound to the model elements in the request.
Modifying single attributes worked just fine (from dialog and programatically). A new element we add to the model tree shows up in the dialog and seems to work equally fine, but when we trigger the service call to send the collected data, every change to the model data is send except the new added element. It just won't be send.
What's the problem here? Seems to me this must be somehow related to the supplying relation role maybe.
What code do you need to look at and how do I mark code in the new forum editor so it gets displayed properly formatted?
Thanks,
ok

Hi,
Can you tell me which code are you using currently for transferrring the data? It might help me to figure out what your problem is.

How to add field length constraints when using an existing JavaBean model

Within our current project we used a O/R mapping tool to generate our JavaBean model. For e.g.
public class Person{
private String name; ...getName() ...setName(...)
}
The whole model is used within our Web Dynpro project. Now it's a requirement to implement field length constraints. Normally this is no problem using ISimpleType like the following:
attributeInfo = wdContext.nodePerson().getNodeInfo().getAttribute
(IPrivate...IPersonElement.NAME);
ISimpleTypeModifiable type = attributeInfo.getModifiableSimpleType();
type.setLength(60);
But we've got an runtime exception that it is not allowed to modify the models datatype:
com.sap.tc.webdynpro.progmodel.context.ContextException: AttributeInfo
(Basics.Person.name): must not modify the datatype of a mapped attribute
at
com.sap.tc.webdynpro.progmodel.context.AttributeInfo.getModifiableSimpleType
(AttributeInfo.java:337)
The question is how could a workaround look like. Or is there nothing like that and we have to build a dictionary type tier upon our JavaBean model. Any ideas ?
thx,
s.w.

Sabine,
You may:
1. Import JavaBeans model
2. Create DDIC type with necessary constarints (string-based, max. length 60)
3. Open editor for target model class and change type of property.
See my blog /people/valery.silaev/blog/2005/06/29/apojo--almostplain-old-java-objects-as-model (section "Tweaking model classes") for details.

Importing Complex JavaBean model into WebDynpro

Hi,
I am trying to get Data from the EJB, in my Case, Command Bean to WebDynpro.
So i followed this thread:
<a href="/people/balaramnaidu.bankuru/blog/2006/04/23/importing-complex-javabean-model-into-webdynpro-by-creating-relationships-for-the-model-classes in WebDynpro</a>
But one thing does't work here:
I can't import the Complex type java.util.Collection.
But i need to get Data from a DB-View into my WebDynpro.
Is there any other chance to do that?
Here a CodeSnippet from my Command Bean Class:
public BusinessDelegate() throws CreateException
 try
 Context ctx = new InitialContext();
 OracleSessionLocalHome home = (OracleSessionLocalHome)ctx.lookup("localejbs/OracleSessionBean");
 session = home.create();
 } catch (Exception e)
 e.printStackTrace();
 public void getAllOracleDetails()
 try
 OracleDTO helper[] = session.getOracleData();
 oracleDetailsList = new ArrayList();
 for (int i = 0; i < helper.length; i++)
 oracleDetailsList.add(helper(i));
 } catch (Exception e)
 e.printStackTrace();
OracleDTO is my HelperClass, where i made all Variable-Declarations I need in the View.
Any ideas?
Would appreciate that!
Bernd

You are not unable to import collection type means u are not able to see that variable in attribute list while importing the model?
This may be due to you have not added getter and setter function for that collection type.

Add HTTP Printer Model????

Hi! I'm trying to figure out how am I supposed to add a new printer model when it's not already in the list? Right now I created a new printer policy to install an http printer. The printer I'm trying to install is a Xerox WorkCentre 5755 so it's NOT already in the list of available model that we can choose. I then upload my own driver, select for which OS and if it's x86 or x64. But each time I get stuck with the "Model name". How can I update my server?????? Is there any procedure or faqs about this? This feature is useless if we can't update it!
Any help will be helpfull!

Hi Spond! I must have missed my coffee this morning. But, even after reading the doc it's still not possible. Because I need to install a printer that uses an IP address to send the job (I need to create a TCP port in Windows ex.: IP.111.222.333.444). So it's not a local printer, it's not a SMB or HTTP printer and it's not an iPrint printer. The only option left to me was to create a bundle to send the driver to each pc and install the printer by using rundll32, regsvr32, etc. commands. Not very easy but it get the job done.
Thanks anyway for the help!

Add new row to a table

Hello!
I'm using JDev 11.2 and I'm trying to add a new row to a table object (using create insert)
the catch is this-
and the new empty row that will appear- I want a value set instead of one of the values- so the user can choose which value to insert
do you know how can this be done?
(just to be clear- i know how to add a value set, I know how to add new row- dont know how to make the new row contain value set field)
tnx for your time
Talya

If you use a model driven list of value on the attribute in question this should work automatically.
Have you setup a LOV on the attribute? Have you (on the attribute) checked that the ui-hint is set to selectOneChoice?

Add new column to a jtable by pressing a button

Hi
I am writing a program that have Jtables and user can add one or many columns to one of those Jtables by pressing a button and that column type user can select by from a combo box.
there have to be column types for select integer type,float type,String type or jcomponent
I need you help to make that specific jtable

Hi pro_udara,
It can be done this way : while treating the mouse event, you just build a new table model and you refresh your JTable with the new model.
See how to [*create a table model*|http://java.sun.com/docs/books/tutorial/uiswing/components/table.html#data]

How to remove songs/albums from Iphone 5 S and itunes library inorder to add new songs

I have an Iphone 5, 7.1.2 model. I have been attempting to add new songs onto my phone but do not have any available space. Although I have deleted and removed apps and other space eating products from my phone, I still do not have enough space to add the new songs that I would like to include on my phone. The final option would be for me to remove some songs from my phone that I no longer listen to. Problem is, I can't seem to find a way or any direction on just how to do that. Wonder if anyone has successfully removed songs from their phone and/or library as a way to free up space to replace them with new songs?

What are the key benefits and limitations of new pricing model of X5-2?

What are the key benefits and limitations of new pricing model that started with X5 version?

1. Elastic Configurations
Size/price hardware by the number of servers; Fixed configs no longer required
Start with 2 Database Servers and 3 Storage Servers. Incrementally add database or storage servers online.
2. Capacity-on-Demand (CoD)
Upon installation, activate 40-100% of the cores per server and reduce software licenses; Applies to Eighth Rack now too
Activate and license more cores when needed; Active cores may not be deactivated
3. OVM and Trusted Partitions
License software on Virtual CPUs within a VM; Ideal for special-purpose DB options
You can mix different combination of options for different DB on one Exadata.
OVM has no License cost; support is included with premier hardware support
Limitation:
At least 40% of usable cores on the machine must be licensed for Oracle software
Cannot use both OVM and CoD to license less than 40% of cores
A server must be virtualized or non-virtualized – not mixed
A RAC cluster can mix virtualized and non-virtualized servers
4. “Flash Drive” License Metric for EF Storage Server Software
$20K/drive; 8 flash drives/EF server vs 12 disk drives/HC server = 33% higher list
Can transfer licenses between Flash Drive (2 licenses/drive) and Disk Drive (1 license/drive) – part # is the same

How Do I add new fields to Repeating Frames in existing Report

Hi,
How do I add new fields to Repeating Frames in existing Report. The Report has 2 GRPFR, 1 HDR and 2 Repeating Frames. I would like to add a new field(column) to inner most repeating frame. I added the new golumn to QUERY and GROUPs in Data Model. After adding the new column to inner most Repeating Frame in Layout Model, the Layout model is losing all other frame and it is showing only the modified one.
How do I add new column to repeating frames without disturbeing other frames.
Any hellp will be appreciated!!!!!!!!!!!.
I am using Oracle Reports 6i.
Thanks,
Ravi.

you must work in your layour editor
expand your repeating frames do it more big
for add your new items or field. after you inserted or add, can you put more little your repeating.
too can you to do one copy of one field in your repeating frame and assign it in his source your new item in your data model.
normally i begin with the principal frame and go one by one internally.

Can you provide the correct code snippet?
The provided code snippet:
EntityDefImpl lnewEntity = EntityDefImpl.findDefObject("model.entity.Applicant");
aNewEntity .addAttribute("FirstName", "FIRST_NAME", String.class, false, false, false);
The variable references are different - lnewEntity / aNewEntity
Can you do a null check if you add the attribute?
if(aNewEntity != null) {
aNewEntity .addAttribute("FirstName", "FIRST_NAME", String.class, false, false, false);
Thanks,
Navaneeth

How to add new Measures in WEBOSA (Measures are already present in Mviews but needed to be mapped to cube)?

Hi
I am using WEB OSA (Oracle Sales Analyzer) cubes.
Now we had a requirement to add new measure to the existing cube. In the materialized views we successfully added the new column. But coming to cubes we are unable to map the new measure to View. We are using Express Relational Access Administrator for modelling the cubes.
In Cubes I created the measure. and in view also i added the new measure in data base. but in administrator i am not seeing the newly added column.
need ur help on the same.
Thanks in Advance
Sravan.

Hi Sravan,
My memory of these Oracle products are a little fuzzy since we stopped doing development on RAA/RAM back in the year 2000 - exactly 15 years ago!
I recall that the Relational Access Administrator i.e. the RAA admin tool stores the sources i.e. Tables or Views that you include in your project as a set
of metadata in the Warehouse Metadata tables or known as the "WH" tables. I believe your issue is one that the definition of the view as stored in the
WH metadata tables does not include your new measure view column. I believe there is a way to "update" the definition of the view as stored in the
WH metadata tables. I believe there is a wizard that you can run that will show the current and new version of the source table or view and allow the
RAA to update the source definition to the new definition. At this point, you can hopefully map your model measure to the source view column and then
run a new build.
Out of curiosity, please provide the versions you are running for:
1) The windows O/S that you are running the Express Relational Access Administrator
2) The version of the Express Relational Access Administrator
3 The Oracle database version
Finally, please send me a note as to why you are still using this very old (but good) technology. Another words, do you feel the
more recent offerings from Oracle do not satisfy your business requirements or some other reasons for not modernizing your
applications?
Thanks,
David
