Constructor Detail

ParameterManager

public ParameterManager(Applet anApplet)

Create a parameter manager for use within an applet.
One parameter manager can be used for multiple server beans.

Parameters:

anApplet - a reference back to the parent applet used to get parameter values.

Method Detail

getParameterInfo

public String[][] getParameterInfo()

Returns a list of parameter details in a form suitable to use with Applet.getParamInfo().

Returns:

an array with one row for each parameter.

parameterizeServerBean

public void parameterizeServerBean(ServerBean bean,
                                   String defaultRMIhost,
                                   String defaultHTTPhost,
                                   int defaultHTTPport)

Sets a ServerBean's RMI and HTTP parameters by looking for corresponding applet parameters.
The bean methods getRMIHostParamName(), getHTTPHostParamName(), getHTTPPortParamName() provide the applet parameter names.
Adds a reference to the bean to a set which is used to support getParameterInfo().
Only uses the method parameters defaultXXX below if it can't find the appropriate applet parameter.

Parameters:

bean - the bean whose RMI and HTTP settings will be configured.

defaultRMIhost - default server to use when an RMI host parameter value isn't found

defaultHTTPhost - default wrapper servlet host to use when an HTTP host parameter value isn't found

defaultHTTPport - default port to use (usually 80 for web server, 8080 for servlet container)

configureServerBean

static void configureServerBean(ServerBean bean,
                                String RMIhost,
                                String HTTPhost,
                                int HTTPport)

A convenience method allowing an application to set a ServerBean's RMI and HTTP parameters. See parameterizeServerBean() for a more useful method for applets.

Parameters:

bean - the bean whose RMI and HTTP settings will be configured.

RMIhost - the RMI server to use

HTTPhost - the HTTP server (wrapper servlet machine) to use if direct RMI connections are not available

HTTPport - the HTTP port to use (usually 80 for web server, 8080 for servlet container)
