Creating DAO layer from java beans(setter and getter methods)

Can anybody explain me how to create an adapter layer (DAO layer) from java beans with no connection and transaction code inside DAO layer?

Sure, have another layer do the transaction work.
Your DAO would make us of this layer.

Accessing Custom Controller from setter and Getter methods

Hi Gurus
How can we access the custom controller from setter and getter methods,is there any way to do that.
Thanks & Regards
Rajasekhar

Hi Steve.
Thanks very much for valuable information, the main controller class is getting tracked in mo_owner which is declared as CL_BSP_WD_VIEW_CONTROLLER, and I'm getting the reference through
mo_owner ?= owner. (since mo_owner = owner is not getting converted of type mo_owner ). After doing this on whatever the contexnode class (say zl_xxxx_xxx_cnxx) the corressponding context node values are getting turned as <#ERROR IN METADATA.
I mean when I'm checking the configuration in bsp_wd_cmpwb configuration tab -> Available Fields->Enlarge the contex node->BTSTATUS (say for Example) there the values are showing as <#ERROR IN METADATA , After executing the above procedure
I cross checked several times before and after redefining the context node method IF_BSP_MODEL~INIT, before redefining this method UI is working fine, after redefintion UI is throwing below error .
Exception Details
CX_SY_REF_IS_INITIAL - Dereferencing of the NULL reference
Method: CL_BSP_MODEL=>IF_BSP_MODEL_BINDING~IS_ATTRIBUTE_VALID
Source Text Row: 13
Thanks & Regards

Regarding setter and getter methods

Hi,
Can anybody tell me the use of setter and getter methods in webdynpro .
It is generated when we set the calculate property of value attribute to true .
Thanks a lot .

Hi Jain
setter and getter functions will be created when you set the calculated propertyto true
Consider the following scenario where in you can get some basic idea
1) First insert a Child "Image" UI Element
2) Create a Context in a view in which you are using Image UI Element
3) Value Node
Name : Image
Cardidality : 1..1
4) create 2 Value Attributes
4)a ImageAlt (Calculate property - true) //this will create getter and setter methods
4)b ImageSrc (Calculate property - true) //this will create getter and setter methods
5)Bind the properties of Image
alt - Image.ImageAlt
source - Image.ImageSrc
6) in getImageSrc()
retrun "XX.gif"
7) in getImageAlt()
return "Image Not Available"
you can even achieve getter and setter methods by doing the following procedure
goto implementation tab-> rightclick -> source -> generate Getter and Setter methods...

Doubts in CMP Setter and Getter Methods

Hi. Just like to clarify something on CMP.
May I know if there are 6 fields in my database table and I declared only getter and setter methods for 5 of the fields only, will this post any problem in WL8.1?
Also, suppose I have 6 fields in my database table and I declared 6 setter and getter methods. Throughout my program I only trigger 2 setter methods, will the other 4 setter methods that I didnt trigger set a null or 0 to the fields (since I didn't set any value to them)?
Thanks and appreciate.

Unset fields will usually be set to their default value, i.e. null for Objects. You don't have to define / execute setters for columns in the database unless they are non-nullable.

How to Create adf table from java bean

Hi,
How to Create adf table from java class (Not from ADF BC).
Thanks
Satya

@vlsn -- you have to follow what shay said.
Do the following in Model layer ::
create a table property java class with your columns setters and getters like :
*public class gridProps {*
private int sno;
private String orderNum;
*public void setSno(int sno) {*
this.sno = sno;
*public int getSno() {*
return sno;
*public void setOrderNum(String orderNum) {*
this.orderNum = orderNum;
*public String getOrderNum() {*
return orderNum;
Create another table java class which will populate the values to your column values and return the collection :
*public class gridPopulate {*
private List<gridProps> gridValues ;
*public List<gridProps> setToGrid(ArrayList<ArrayList> valuesToSet) {*
*if (valuesToSet == null) {*
return gridValues;
gridValues = new ArrayList<gridProps>();
if(btnValue.equals("completeBtn"))
return gridValues;
for(ArrayList<String> tempArr:valuesToSet)
gridProps gp = new gridProps();
gp.setSno(Integer.valueOf(tempArr.get(0)));
gp.setOrderNum(tempArr.get(1));
return gridValues;
Right click gridPopulate class and create this as data control.This class will be seen in Data control list.Under this data control,Drag the grid property collection(created earlier) to your page.Then execute your binding(gridPopulate) according to your logic.

Auto Javadoc for Setter and getter methods

Hi
Is there a way to include javadoc while creating a Setter and getter itself?
Thanks
Tanjith

but why addign javadoc to a getter/setter anywhy?Oracle [url http://download.oracle.com/docs/cd/E16162_01/apirefs.1112/e17483/oracle/jbo/common/AccTravDefImpl.html#getAccTravQualifiers()]does, so it must be OK :)
But as Timo says, there's no automatic way that I know of. I suppose you could do something like that by making your own code template.

Customizing order for setter and getter methods in ViewRowImpl

I have problem to calculate value for one attribute of my viewObjectRow which depends on values of other attributes in my row and result of stored function. I menaged to do all of this except getting value one of attributes that i need. Order of calling getter methods doesn't fit me. I tried lot of things, but nothig worked! Is there some way to customize calling order for getter and setter methods in ViewRowImpl and How?
Thanks!

Set and get values with vector

I have a class that that querys a db and sets a value of the result to a vector array. Is it possible to set and retrieve that vector array using the set and get methods?
ex:
my class:
sql = "Select ...";
Vector fName = new Vector();
rs = sqlStatement.executeQuery(sql);
if (rs != null) {
while (rs.next()) {
fName.add(rs.getString("fName") + "");
rs.close();
setFName(fName);
how would I set up the set and get methods???
thanks

I am unsure of what you are asking:
A Vector has set and get methods for it, you use indexes of the array to say what element you want to work with.
If you are asking how do you know what elements of the Vector contain which data columns, you have to remember how you put them in.
If you are asking if you can use set to load the Vector: then NO, you have to have elemenets already there to change, use the add method.
If you are asking how to access the elements of the Vector you use an Enumeration:
for(java.util.Enumeration e = v.elements(); e.hasMoreElements();){
s = (java.lang.String) e.nextElement();
vl.add(s.substring(0, 12));
If you are asking something else: please elaborate what you want--my brain may not be very functional this morning.

Create web service from java code in Jdeveloper 11.1.1.5

I am try to create web service from java code by default it is connected to Integrated web logic server and generate a
WSDL like this.
http://localhost:7101/javaexcel-project1-context-root/MyWebService1Soap12HttpPort.
please tell me how we can change this local host to our needed Host and how to deploy this web service to web logic server.

Hi,
Just right click on your project and deploy it to your application server (Weblogic Server (Not the Integrated server)). {Before that, you have create your Application server connection in the Jdeveloper).
After deployment open the Admin console of the weblogic server and find your ear of the project.Click on that (Go to the "Testing tab") and you will get the "WSDL" (Concreate wsdl) and "Test Client" of the Project.

When i create new layer from background the new layer then covers up the background. It previously did not do this.

I am a rookie. This worked on previous pics but I apparently have clicked something I shouldn't have. Thanks for any help.

The problem with Actions is that as a new user, you are not going to know what steps are happening when the Action runs. The action could be deleting the background layer, for instance. Is the action one that came with Photoshop? If you sourced it from somewhere else, can you give us a link?
There is also some ambiguity in the language you use. Not your fault. But when you say 'create new layer from background' to me that probably means you are copying the background layer. If that is not the case, could you give a more detailed description of the steps you are taking?
Do you know how to upload a screen shot? If you are using Windows 7 or 8, you can use the Snipping tool to drag across your image and layer panel. Save the image, and upload to this thread using the little camera icon.

Created a pdf from a word-file and inserted formfields. The fields works in other pdf-readers(nitro,reader etc), but not in adobe reader and acrobat. Please help.

Hi,
I have created a pdf from a word-file and inserted formfields for a work related file. I've used nitro pro to create the formfield. They works in nitro, reader, foxit etc. but not adobe reader. From page 3 and out, the font wont show when writing in a formfield. Some formfield doesnt even show.
Please help me fix this (hopefully before the presentation at work friday) :-)
File in question: Dropbox - Byggeplassperm_bico_prosjektledelse_2.pdf
Kind regards

Agreed. Adobe makes no claims that their Reader will work properly with forms made from third party software.
