How To Add Certificates In Java Mobiles

How to Install Nokia S40 Security Certificate
Series 40 is a software platform and application user interface (UI)software on Nokia's broad range of mid tier mobile phones. It is theworld's most widely used mobile phone platform and found in hundreds of millions of devices.
Series 40 is a simpler operating system variant than the higher end S60 (which is based on the multi-tasking Symbian OS ). Because S40 devices do not support true multi-tasking and do not have a native code API for third parties, its user interface may appear to be more responsive and faster than other Nokia platforms. While Series 60 can run more applications and is recognized as"Symbian" more so than the simplistic Series 40, Series 40 does not have support for Symbian apps—rather, Series 40 runs Java ME applications such as FileExplorer (which allows the user to managefiles and folders on their phone), but these java applications keep on asking for permissions on every single operation, which makes things fussy. Here we'll show you how to get rid of this fuss..

Changing Logo and icons:

To change any image in an application, just replace the corresponding image with another image with same name with the help of MiniCommander. Note that the resolution should be same.

Translating and editing:

First extract the class file you want to edit or translate using MiniCommander. Then to edit strings in it, open it with Class Editor. You will see many boxes and text. You can deassemble them with Class Editor. You can also edit text strings, symbols, hex values with it. If you want to edit only the text strings, or want to translate, you can use the Class Translator. When you open a class file with it, it'll extract all text strings. Now you can easily edit and translate them. Now after making necessary changes, save it. Then add it to the archive with MiniCommander. Previous class file will be replaced with newer one. Now rename the archive to _jar with MiniCommander. Then with your phone, rename it to .jar to install.
