Autocomplete was not working for JSF tags in my Eclipse. I googled it and finally found the solution on http://www.mkyong.com/jsf2/how-to-make-eclipse-ide-supports-jsf-2-0/

Thanx Mkyong.

The different thing I did is; I downloaded javax.faces-2.xx.xx.jar and saved in a specific folder. Then I created a user library with this jar. I did not use “jsf-api-xxx.jar and jsf-impl-xxx.jar“.

Here is the scenario;
-Type something to combobox
-Select something on the list
-Search and fill gridPanel
-Clear combobox and then search again
-It fills gridPanel with value that before we cleared.
I this this is a bug.
If you use Ext.getCmp(‘myCombo’).getValue() or Ext.getCmp(‘myCombo’).lastSelectionText, it does not work.
You have to use Ext.getCmp(‘myCombo’).getRawValue(). This works ;)
By the way comboBox is not readonly.

If you have a web page with full of your copyrighted photos and do not want to visitors to save images in (easy way!) to their local computers. Let me show a trick about it.

In the photo (img) section of the page, we have always something like as following;

     <img id="myImg"
      src="http://www.google.com.tr/logoyapsana/images/templates/google_logo_01.gif"
      width="667" height="472"

Recently, I developed a program that reads imdb.com web page for a specific movie and downloads movie info and images. Then, it merges the thumbnails images into one image file.

Firstly, I write the main code, that downloads the image files and merges them and save the merged image to system.

Note 1: In the code, arr variable is an ArrayList holds the picture urls.

Note 2: Image class is in “System.Drawing”


                                        Image[] images = new Image[arr.Length];
                                        for (int k = 0; k < arr.Length; k++){
                                             images[k] = Utils.DownloadImage(arr[k]);
                                        }
                                        Image mergedImage = Utils.MergeImages(images);

If you changed your computer and want “your PL/SQL developer login history and preferences” as well in your new computer. Copy the following folder to your new computer in the same path format!

C:\Users\[username]\AppData\Roaming\PLSQL Developer

If you need only the login history, open the following file:

C:\Users\[username]\AppData\Roaming\PLSQL Developer\Preferences\[username]\user.prefs

In the file, copy [LogonHistory] part to your new user.prefs file. It’s encrypted but it does not matter. PL/SQL Developer will dencrypt it :)

ORA-14047: ALTER TABLE|INDEX RENAME may not be combined with other operations

When we try to rename  table or index name in Oracle, we use a simple command as following;

alter table [prev_table_name] rename to [last_table_name]

If we put into schema names to this command, we can deal with ORA-14047 error. This error raise when we put schema name in front of the last_table_name.

alter table hr.[prev_table_name] rename to hr.[last_table_name] >>> RAISES ORA-14047 ERROR
alter table hr.[prev_table_name] rename to [last_table_name] >> CORRECT ONE

 

It is same with Index renaming.


How to remove spaces in a string in Shell

I experienced that when you connect to Oracle database from shell and get some data from the table, if the length of the column value is more than 80 letters. Shell puts space in every 80th letter automaticly. I do not know why, but it is really interesting. I counted the number 80 for my environment. It may differ in different systems.

Anyway, I need to remove that interesting spaces. So here is a script (more...)
