Tutorial: install Java on the IPhone
This is a tutorial, that shows step by step how to install Java on the IPhone.
First of all I'd like to say we all want to use legal IPhones and operators. So everything written below is for testing purposes only . Hopefully this technology will be avaliable on all IPhones sold worldwide. You also might need to recover your IPhone, so make sure you backed up all your data. I personally did everything without any problems and needs to recover. Everything you do is your responsibility, etc...
So let's start, because it's worth it! It's just one evening and you will be able to create your personal Java application, compile and run it on the IPhone, and amaze all your friends .
There are two steps:
- Go to Settings -> General -> Auto-Lock and set it to Never. This will avoid some troubles during installation.
- Run Installer. Repository for Terminal should be already there (BigBoss), because it is in latest Community Sources.
- Add repository http://apptapp.saurik.com for Cydia Installer and refresh
- Go to Install -> System
- Find Term-vt100 - Mibile Terminal App. I used version svn278. Install it.
- Go to System again and find Cydia Installer - The Future of the IPhone. I used version 1.0. Install it.
- Exit. Restart IPhone. Two icons for Terminal and Cydia should appear.
Here are some screenshots for Step1:
Step 2: Go to Cydia Installer and install Java.
- Run Cydia Installer.
- Go to Install - Java section. You will find many programms there.
- Select IPhone/Java. It will install most of the needed packages, which includes vm, libraries, etc.
- Click confirm and wait a little bit.
- Go to Java section again and install Jikes package (itwill be probably the only one left). Jikes is a compiler.
- Go to Installed Packages tab. Check that Classpath, IPhone/Java, JamVM, Jikes are installed. Several other packages will be there too (Java SQLite, JocStap, etc).
- Exit Cydia and restart IPhone. Congratulations!!! You're done installing Java.
