Method Details

urlFromSystemId

public static URL urlFromSystemId(String sysId)
                           throws IOException

Method that tries to figure out how to create valid URL from a system id, without additional contextual information. If we could use URIs this might be easier to do, but they are part of JDK 1.4, and preferably code should only require 1.2 (or maybe 1.3)

Throws:

IOException

uriFromSystemId

public static URI uriFromSystemId(String sysId)
                           throws IOException

Throws:

IOException

4.1

urlFromSystemId

public static URL urlFromSystemId(String sysId,
 URL ctxt)
                           throws IOException

Throws:

IOException

urlFromCurrentDir

public static URL urlFromCurrentDir()
                             throws IOException

Method that tries to create and return URL that denotes current working directory. Usually used to create a context, when one is not explicitly passed.

Throws:

IOException

inputStreamFromURL

public static InputStream inputStreamFromURL(URL url)
                                      throws IOException

Method that tries to get a stream (ideally, optimal one) to read from the specified URL. Currently it just means creating a simple file input stream if the URL points to a (local) file, and otherwise relying on URL classes input stream creation method.

Throws:

IOException

outputStreamFromURL

public static OutputStream outputStreamFromURL(URL url)
                                        throws IOException

Method that tries to get a stream (ideally, optimal one) to write to the resource specified by given URL. Currently it just means creating a simple file output stream if the URL points to a (local) file, and otherwise relying on URL classes input stream creation method.

Throws:

IOException

toURL

public static URL toURL(File f)
                 throws IOException

Helper method that will convert given file into equivalent URL. Encapsulated as a separate method to allow for working around problems with deprecation of File.toURL() method.

Throws:

IOException
