HOW TO MAKE JAR HANDLER FILE

Do you want to adjust java apps by yourself using your phone?

Here are tools that you need if you want to adjust a java application (ie, Opera Mini, etc.).

1. X-Plore (1.42):File Manager that is used to extract jar archives and edit manifest.mf’s.
2. Zntxhan (2.04):File Editor that is used to edit .class files and other files. There are also other files that are supported by zntxhan. (python looked-for)
3. Assumed role Designer (1.40):Assumed role Editor that is used to edit or start assumed role files for icons, skins and etc of a java file. (python looked-for)
4. JarBoom (2.0):Compiler that is used to compile or pack the extracted java archive. Using this doesnt give me an consent disastrous error upon installing the packed jar. (python looked-for)

Thats it! For a basic need, that was ample. For python based apps, you need the python installer and the module pack to run persons apps.

For other s60 such as s60v3. There are also corresponding apps for your phone version of the said apps on same name

or s40, I havent tried it yet but it was doable though I see it a modest harder. And we will not settle on that. ;P

I hope you get a modest thought about the apps. Up next is the detailed and step by step tutorial on how to adjust java apps

We will now start on the basic of modding. I will lecture you how I learned this material. So the allotment information process is Shankru’s way. *credits goes to my mentors and other people that gave me information about modding Ankitkumarpal,jbpsedu,faishaln73,handler and {your_name_here} So let’s proceed.

1.Preparing the java file:for develop we want to adjust an Opera Mini 5 final, we use xplore to locate it, click it and we see a lot of files. All we had to do is to extract all files in JarBoom’s unjar folder using X-plore.

2.Editing the Manifest:Look for META-INF folder and surrounded by you will see a MANIFEST.MF file. You can edit it with X-Plore by pressing [8]. Edit the de rigueur details you want to exchange (ie, MIDlet-Vendor, MIDlet-Version, MIDlet-Name, MIDlet-Info-URL, MIDlet-Description and MIDlet-1). Make sure when saving, the Save as unicode selection is NOT
check.

3.Editing the Class Files:Using Zntxhan, locate any .class file via Listway. We need to edit these to exchange the ma?tre d’h?tel and place a ploy on it. In Opera Mini 5 final the ma?tre d’h?tel is located in f.class (this differs on every java apps). You can use the functions of Zntxhan to quest for the thread of the ma?tre d’h?tel in the class. With editing, save and delete the made .class_bak (which serves as backup but we do not need this)

4.Editing the Icon:Here we will use ImageDesigner, you can edit the i.png file that was extracted to any design you like, just make sure you made it small to fit in as an icon, 50�is ample (I guess).

5.Compiling:With we had edited what we looked-for to, we’re off to compiling the files back into jar file again. In this case, we will use JarBoom, point out Tools-Compile and locate the manifest.mf surrounded by meta-inf folder and give name to your jar file, wait in anticipation of the packing completes.

That’s it! Try your modded om. If it installs, splendid! You did it. This is all just for now, I hope you get a modest thought about modding and we will proceed to deeper topics in future. Always note that, what I post here was based on my information about this topic. We may have our own style or way. Explore and you will learn.
