> [tut] modifying a java application with screen shots
Bookmark topic
I’m starting this thread on how to modify a java application particularly a Opera Mini™ 4.2 version.
You will need a HexEditor and a Opera Mini™ 4.2 version (.jar) file.
Install the HexEditor application on your PC. Now we can start modifying a OM4.2.jar.
For the HexEditor Application. Just Search On Google. Madami po kasi Freeware lang ito. can't attach dito kasi naka-cp mode lang ako ngayon.
A.Open your OM4.2.jar with WinRar (I know everyone knows this WinRar application).
This part you will learn how to edit your proxy url of OM4.2
1.For the proxy url of the OM4.2 to be edit drag the a.class file on any folder.
2.Start your HexEditor application and open the a.class on it.
3.Press Ctr+R (to search and replace) “server4.operamini.com:1080” and replace your desired proxy url.
In this tutorial I’m gonna use the VASNET url (working as of the day I posted this thread).
“http://m.smartvasnet.com.t9space.com/power/m/http/91.203.96.125:80/”
4.Click "OK" (not replace all) because there are 2(two) “server4…” can be found in this file.
5.It will turned into red text your edited line.
6.Highlight the red text and take note the “Length” that can be found at the bottom of HexEditor window.
7.In this tutorial. I had a 43 in length.
8.Highlight the character before the red text and select “Edit” on menu and select “Fill selection…”
9. Click "OK".
10.Save the file and drag back the a.class to winrar window. Disregard the a.class.bak
11.Now your done with the proxy url of your OM4.2
This part you will learn how to see your name in OM4.2's About
1.Drag the f.class on any folder from your WinRar window.
2.Open HexEditor application and open the f.class on it.
3.Press Ctr+R (to search and replace) “ v. 4.2.13337, 20081205” and replace your desired name.
NOTE: There's a space before “v. 4.2.13337, 20081205”
THEREFORE: It should also have a space before your desired name.
In this tutorial I'm gonna use the "modified for ESATO members"
4.Click "OK"
5.Take note the Length of your edited line. In this tutorial, I had "1B" in Length
6.On menu tab Go To - Edit - Fill Selection…
7.Enter the Length "1B"
REMINDER: If your desired name has a single character just add 0(zero) before it.
For Example: You found 4 in your Length, your Fill Selection is "04".
If you found C in your Length, you Fill Selection is "0C".
Get it?
8.Save your project and drag back the f.class to WinRar window. Disregard the f.class.bak
There are so many ways modifying a jar application but this could be the simplest way to modify for the beginners.
The file that has the extension name ".bak" are the back-up files of your edited class file. If you think that you are not sure with your edition just rename and delete the ".bak" file and it will bring back the original ".class" file.
Hope In this Tutorial, Maging moders na lahat in a very simple way. Thanks ESATO.
