Handy code snippets - ADF

Here I am putting some handy backing bean code snippets which i got from other's blog(thank you for all of them) for my reference.

1. To remove selected row(highlighted row) in a table

        RowKeySet ps = <tableBinding>.getSelectedRowKeys();
        ps.clear();
        AdfFacesContext.getCurrentInstance().addPartialTarget(<tableBinding>);

LOV selection issue in ADF - Key Attribute

I have faced small issue in LOV selection today.

Whenever you select value in LOV, always first value was selected. Even If you input valid value and tab out , first value was getting selected.

Solution: In my case reason is straightforward.

 I have created view accessors to have LOV for a attribute.

The source VO has only one attribute and I have not marked it as "Key Attribute" check box.

So, always make sure VO has primary key or mark the attribute to avoid issues like above.

Hope it helps!

Unauthorized access to server localhost 8080

Hi,

I have installed Tomcat 7 and when I try to connect to server using default port
http://localhost:8080
it was asking for user name and password.
Below is the screen shot

Then I realized is that issue is because of default port 8080. I have installed Oracle in the same machine and it was using 8080 port.

To overcome this issue, I changed default port for tomcat by following below steps

In the tomcat installed directory

navigate to "conf" folder -> Open "server.xml" file

Inside server.xml file try to find below statements

<Connector port="8080 protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />


change the default port to different no other than 8080

for Ex: here i have changed to 8181
<Connector port="8181" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />


and it works fine for me.
