Jijawi (Jijawi Is Just Another Web Installer) is an easy way to distribute your PHP Web application to your users. It comes with a complete modular structure, which allows you to modify the installer as much as you want with the least possible effort. Jijawi supplies you with a system check and a MySQL module by default, so you can get the most common installer running in a few minutes.
With NBM Center, you can use an ordinary Web server with PHP support to distribute your Netbeans Modules to the users of your application. Simply upload the .nbm files to the server and the appropriate autoupdate descriptors will be generated accordingly. For even more convenience, it is possible to upload the .nbm files via a Web form. But this feature should be used very carefully and probably not on a public Web server.
