Interface to be implemented by objects that can load resources. An ApplicationContext is required to provide this functionality.

Method Detail

getResource

public Resource getResource(java.lang.String location)

Return a Resource handle for the specified resource. The handle should always be a reusable resource descriptor, allowing for multiple getInputStream calls.

• Must support fully qualified URLs, e.g. "file:C:/test.dat".
• Must support classpath pseudo-URLs, e.g. "classpath:test.dat".
• Should support relative file paths, e.g. "WEB-INF/test.dat". (This will be implementation-specific, typically provided by an ApplicationContext implementation.)

Note that a Resource handle does not imply an existing resource; you need to invoke Resource's "exists" to check for existence.

Parameters:

location - resource location

Returns:

Resource handle
