How to Sign and Re-size Screen Resolution of Java Application Online for Free

Many times installing Java Applications or Games that require access to an internal source, either the phone memory, flash card, Internet or cell, you always face a problem when the phone rapidly ask for permission to access the application. This happen with all unsigned Java apps like UC Browser, Bolt, Opera Mini etc which was unofficially modified. Such apps will ask for permission to read or write content from/to phone.

But if it is a signed app, there will be no such problem at all. But how to do it? I've already publish different method but this time an another online way to do it which let you easily signed any java app directly online.

See here is a simple procedure to sign jar files: You need any java file uploaded anywhere online or just upload your .jar file to any free file hosting service and copy the direct link of this file to following site: On-Line Certifier (Its a Russian site so if you can't understand it than open following English translated site by Google Translate: Click Here or in case Google Chrome it'll be auto translated)
Now at On-Line Certifier select your phone model and required Permissions for your java MIDlet which you needed. The File System and Internet Access is common to required for browser apps. Than after paste the direct link of jar file on the field: Enter the address of the file. JAR (URL http://) and click on Certify a Midlet.
The next page will show you the links to the signed .jad and .jar file. Download the jad and jar files and transfer both jar and jad to your mobile and run the .jad file to start installation.
You may also needs to transfer the exp.cer or halmer.cer to your phone if the certificate is not installed on your phone, download and install them. You can download them at same page where you downloaded the .jad and .jar signed files. See the option "Certificates for your phone" and click on "Certificates". Certificates are different for Nokia or Sony Ericsson phones. 
How to Install the certificate in the phone: 
Series 40: Through MobiMB (MobiMB.exe) transfer the contents of the folder named "user" in archive into the phone "A: \ Hiddenfolder \ certificates \ user \".
Series 60: Transfer the certificate exp.cer (from folder named "auth" from the archive) into your phone using any file manager and installing it on your phone. When installing the note "Installing applications".
Now just find the installed file in the application list and under application property or settings set all fields as "always allowed", now you can use the app without any security warning.

How to Resize Screen Resolution of Java Apps: If you have a java app or game which is overlapped in your phone, means it has different screen size of your phone. For exp your phone has screen resolution of 176x208 but the app has resolution of 240x320. In this condition the app will not run properly and you'll not able to see all options on that app. The solution is to change the screen resolution of app. 
Just open this Online Java Screen Adapter (or this English Translated Page) service and select the file system, screen size, keyboard pattern. Than after paste the direct link of jar file on the field: Enter the address of the file. JAR (URL http://) and click on "Adapt".
The next page will show you the links to the modified .jad and .jar file. Download both the jad and jar files and transfer both jar and jad to your mobile and run the .jad file to start installation.
