Method Detail

onload

public void onload()

Overrides:

onload in class ProcessorModule

init

public void init()

Description copied from class: Module

Initializes the module. Init can be overridden to read the environment variables it needs.
This method is called by Module.startModule(), which makes sure it is not called more than once. You should not call init() directly, call startModule() instead.

Overrides:

init in class ProcessorModule

reload

public void reload()

Reload the properties and driver

Overrides:

reload in class ProcessorModule

unload

public void unload()

Overrides:

unload in class ProcessorModule

shutdown

public void shutdown()

Description copied from class: Module

Shuts down the module.

Overrides:

shutdown in class ProcessorModule

makeUrl

public java.lang.String makeUrl()

Routine build the url to give to the DriverManager to open the connection. This way a servlet/module doesn't need to care about what database it talks to.

Specified by:

makeUrl in interface JDBCInterface

See Also:

DriverManager.getConnection(java.lang.String)

makeUrl

public java.lang.String makeUrl(java.lang.String dbm)

Routine build the url to give to the DriverManager to open the connection. This way a servlet/module doesn't need to care about what database it talks to.

Specified by:

makeUrl in interface JDBCInterface

See Also:

DriverManager.getConnection(java.lang.String)

makeUrl
