Beans.

Some beans illustrate the use of the core snmp classes.

• SmiDisplay is used to display smi object (Smi Var, Snmp Message)
• VarEditor can create smi Var.
• ButtonVar can hold standard smi Var (ex: sysDescr.0 from mib2)
• PduGenerator can create Snmp Message.
• SnmpTube is an asynchronous Transmitter/Receiver of SNMP Pdu.
• GREDLight a light to enhance your gui.
• Parser an interpreter for a simple grammar, used to parse expression containing special variables: Smi Var extracted from a snmp message.
• DataDisplay is a companion to Parser.
• Plotter: line or bar charts to visualize data.
• MibBrowser a Mib browser (for smi V1).

Some examples illustrate beans usage:

• A simple snmp requests generator.
• Processor load for three big monsters.
• Bandwith calculation.
• Mib Browser.

Notes:

1. See how to sign applets in appletviewer: applets making io in files must be signed (according to the JDK1.1 security model).
2. There are some problems mixing heavy/light components. For example if you use MibBrowser, the applet generated by beanbox must be modified by hand (replace Applet by JApplet)...
