SuperEnvironmentLite is a J2EE tool, Java EE tool, for management and monitor GlobalEnvironment. It is a lite version of SuperEnvironment. The main difference is that SuperEnvironmentLite is for developers without runtime management and monitor.
SuperEnvironmentLite is an open source software. It is written entirely in Java.
GlobalEnvironment is an open source program from Acelet Corporation.
It is a platform neutral and vendor neutral J2EE, Java EE utility program. Both SuperEnvironment
and SuperEnvironmentLite are GUI tools (Swing) written entirely in the Java
programming language.
GlobalEnvironment is a global version of java.util.Properties and java.util.Hashtable. Properties and Hashtable are valid within one single Java
VM only. GlobalEnvironment is valid across the whole network in distributed
computing environment.
See
Environment variables in J2EE world for related information.
SuperEnvironmentLite is platform neutral. it has been tested on the following platforms:
SuperEnvironmentLite will be ported to IDEs, such as Eclipse and NetBeans, as a plug-in module.
This is an open source project. Contributors are welcome, especially:
Add help
Port it to Eclipse as a plug-in which is easier to install.
NetBeans plug-in version
Click on the icon or SuperEnvironmentLite menu item on the Tools menu.
Eclipse plug-in version
The Standalone version of SuperEnvironmentLite is a standalone jar file contains the main( ) method. It can be imported into Eclipse.
Standalone version
The released software is a zip file. It contains only one file: superEnvironmentLiteXXX.jar where XXX stand for version number, for example, superEnvironment100.jar. A copy of HypersonicSQL database is embedded with it, as an example. You need to unzip the file and get the jar file superEnvironmentLiteXXX.jar.
It can be run as a jar file, by typing:
java -jar superEnvironmentLiteXXX.jar
When you need to use your own database, you need:
1. Populate the database using GlobalEnvironment. You can download it from SourceForge.net.
2. Put your database driver on the CLASSPATH. For example:
java -classpath myDatabase.jar -jar superEnvironmentLiteXXX.jar
The main panel
Tabs
There are five tabs at the bottom. They are for:
- Double: GlobalDouble
- Hashtable: GlobalHashtable
- Long: GlobalLong
- Object: GlobalObject
- Properties: GlobalProperties
When you click a tab, the corresponding panel will be the selected panel.
Buttons
There are three groups of buttons at the top. The are separated by bigger spaces.
The first group, Edit and Delete are for highlighted items, on the selected tab. For example, as the above screenshot, The GlobalDouble is selected. If you click on the Edit button, the item be edited will be the one with Key equals One.
The second group, Add is for adding an new item for the selected environment.
The third group, Database, Help and Close are for the system, not for a particular environment.
Edit and Add
Currently, both GlobalObject and GlobalHashtable are not input-able by keyboard.
Database
A copy of HypersonicSQL database is included in the software as an example. The database runs as a in-memory database, which is not shared by other applications. This example database will automatically run until you change database to other database (different URL).
Database change will take effect immediately: all existing panels will be refreshed.
The database parameters will be saved with file name superEnvironmentLite.properties under user's home directory.
If you use other database, the JDBC driver must be on your CLASSPATH.
Copy and paste
Copy: Control-c
Paste: Control-v
NetBeans plug-in version: Install
From the main menu > Tools > Update Center >
Select Install Manually Downloaded Modules > Next.
Click on Add button
Then follow the GUI program.
NetBeans plug-in version: Uninstall
From the main menu > Tools > Module Manager
Select SuperEnvironmentLite, the click on Uninstall.
Eclipse plug-in version: install and uninstall
The Standalone version of SuperEnvironmentLite is a standalone jar file contains the main( ) method. It can be imported into Eclipse.
Standalone version: Install
The software comes as a jar file. Do not need to install.
Standalone version: Uninstall
Remove the jar file. Note: the file superEnvironmentLite.properties will be stored under your home directory. You can delete it if it is not needed. But, it is a very small ASCII file, if you do not delete it, there will be no harm to any application.
Other plug-ins for IDEs are:
SuperEnvironmentLite is a self-contained, modular application.
See the source file com.acelet.opensource.superenvironmentlite.SuperEnvironmentLite.java. The method main will tell you how to call it from outside.
This is an open source software with GNU GENERAL PUBLIC LICENSE.
The downloaded source file is much smaller than the binary file. Is the source file package complete?
The downloaded source file is a complete source package. The binary file is bigger because it includes binary code from GlobalEnvironment and HypersonicSQL database.
