Method Detail

loadPropertyFile

public static java.util.Properties loadPropertyFile(java.lang.String name)
 throws java.io.IOException

Create a new properties class and load it with data from a property file.

Searches for file name down class path.

See java.util.Properties class for more information.

Parameters:: name - Name of property file to load.
Throws:: java.io.IOException - file not found.

locateFile

public static java.lang.String locateFile(java.lang.String name)
 throws java.io.IOException

Parameters:: name - property file name
Throws:: java.io.IOException - file not found

unescape

public static java.lang.String unescape(java.lang.String str)

Decode a Java Script escape() string.

Strings passed through HTTP requests are often encoded to ensure they do not cause confusion. This is especially true of cookie values.

Java Script uses the escape() method to convert problem characters into %XX format where XX is the ASCII value of the character.

This method decodes these strings replacing the escape sequences with the original characters. It is fully Java Script escape() compatible.

Parameters:: str - Escaped input string

escape

public static java.lang.String escape(java.lang.String str)

Encode a Java Script escape string.
