Usage

From source file:org.apache.struts.chain.AbstractPopulateActionForm.java

/**
 * <p>Base implementation assumes that the <code>Context</code>
 * can be cast to <code>WebContext</code> and copies the parameter
 * values from the context to the <code>ActionForm</code>.</p>
 *
 * <p>Note that this implementation does not handle "file uploads"
 * because as far as I know there is no API for handling that without
 * committing to servlets -- in a servlet environment, use
 * <code>org.apache.struts.chain.servlet.PopulateActionForm</code>.</p>
 *
