Inserting blank row in table in ADF

Hi All,

Requirment – To create 5 or 10 blank row in adf table.User can enter value in all row and able to perform bulk save or other action.How to do that.

Well for that you need to write a custom method in AMImpl.java as below..

 
    public void insertDefaultRows(){
          ViewObjectImpl ioOrderLines = this.getViewObject1();
          ioOrderLines.executeEmptyRowSet();
          int noOfRows=5;
          oracle.jbo.server.ViewRowImpl emptyRow;
          for (int i=0; i < noOfRows;i++){
              emptyRow = (oracle.jbo.server.ViewRowImpl)ioOrderLines.createRow();
              emptyRow.setNewRowState(oracle.jbo.Row.STATUS_INITIALIZED);
              ioOrderLines.insertRow(emptyRow);
          }
      }

After add to client interface of application module so that it can visible in data control.Go to application module –>go to java tab–>go to client
interface–>select your method from left to right.Open data control you will able to see your method.

Now you can call your method in two ways.

1. call in page binding using invoke action- Right click the jspx or jsff and go to page defintion .go to executable –insert inside the executable
–>invoke action. Provide the ID and select your method from drop down.Make refresh condition as always.

2. Open the jsff .drag drop the custom method from data control and paste as button on the page.When you click the button it will show the blank row.

happy coding with Techartifact.

Setting the value in Different scope in ADF in programmatic way

Sometime in ADF application we want to set the value in different scope programmatic .How to do that.
Use below code to do that.You can create a variable in any scope and put value in it

 
  ADFContext adfCtx = ADFContext.getCurrent();
       Map appScope = adfCtx.getApplicationScope();
       appScope.put("vinay", "true");

Similarly you can get the value of any variable stored in any variable

 
  ADFContext adfCtx = ADFContext.getCurrent();
       Map appScope = adfCtx.getApplicationScope();
    String appScopeValue=  (String)appScope.get("vinay");

Modify or Extending the Shell Template in Oracle ADF – techartifact

Requirment – To modify the template that can be UI shell template or Dynamic Shell template or Any other template which in form of jar in your application

Solution- In one of the requirment i have to create binding for panelspiltter in the template.jspx which in template.jar . I have unjar it modify and implemented the changes and again made to jar.

XXX.jspx in oracle-page-templates-ext.jar. Below is the step by step procedure to do this:

Copy the oracle-page-templates-ext.jar from %MiddlewareHome%\jdeveloper\adfv\jlib\ folder
Create a new folder in drive C like C:\temp\jdev\ and paste the copied jar.
Extract the contents of the jar.Open command prompt and navigate to the C:\temp\jdev folder

You can change the folder by “cd” command
For going to parent folder you can use “cd ..” .
Enter the below command for unjar : 

 
jar xf oracle-page-templates-ext.jar 

or 

jar xf JarName.jar

 

If you that jar command cant recogzied then we need to add the java bin folder path into the “Path” system variables. Ex. “C:\Oracle\Middleware\jdk160_24\bin;”
You can do by right the my computer and go to properties ,go to advance tab .Seach path variable and edit and add this above path as well

If this command work well. then you need to delete the existing jar from temp folder you created. We do this so that we can easily repack a jar later.
Open the jdevloper and open that XXX.jspx . modify or whatever changes you want to make do it.save and close it.Repackage the file in a jar. Open a command prompt navigate to the temp folder we created earlier then run the following command:
Now you have to pack as a jar .Use this command

 
jar cfM0 oracle-page-templates-ext.jar *    
0 (Zero)

or
or 

jar cfM0 JarName.jar

You can give the jar a different name if you like.Now you will Modify libraries and classpath. Open your application in JDeveloper.Right-click your ViewController project and click project properties.Remove the existing Templates in the classpath entries.Add the jar file that we created in the step above.
