public ServletContextLocator(javax.servlet.ServletContext ctx,
                             boolean acceptURL)

                             String dir)

Constructor. A short of ServletContextLocator(ctx, dir, null, false, null).

Parameters:

dir - the directory used when relative path is specified (for getResource(java.lang.String) and getResourceAsStream(java.lang.String)). It must be null, empty, or starts with /.

ServletContextLocator

public ServletContextLocator(javax.servlet.ServletContext ctx,
                             String dir,
                             String prefix)

Constructor. A short cut of ServletContextLocator(ctx, dir, prefix, false, null).

public ServletContextLocator(javax.servlet.ServletContext ctx,
                             String dir,
                             String prefix,
                             boolean acceptURL)

ServletContextLocator

public ServletContextLocator(javax.servlet.ServletContext ctx,
                             String dir,
                             String prefix,

                             String externalPrefix)

Constructor. For example, if prefix is "/WEB-INF/cwr", then getResource("/abc") will look for "/WEB-INF/cwr/abc" first, and then "/abc".

Another example, if prefix is "/WEB-INF/cwr" and dir is "/subdir", then getResource("abc") will look for "/WEB-INF/cwr/subdir/abc".

Parameters:

dir - the directory used when relative path is specified (for getResource(java.lang.String) and getResourceAsStream(java.lang.String)). It must be null, empty, or starts with /.

prefix - the directory to prefix each directory specified (for getResource(java.lang.String) and getResourceAsStream(java.lang.String)). It must be null, empty, or starts with /.

acceptURL - whether to URL (such as file:/, http:// and ftp://) are accepted. In other words, Servlets.getResource(javax.servlet.ServletContext, java.lang.String) will be used.
