PrEd is a Java based graphical utility to find and edit Java property files in JAR, WAR, EAR and other kind of ZIP archives. It is the perfect tool for customizing Java applications, which use XML and Property files for their configuration.

• Search for XML and property files in JAR and WAR archives.
• Edit property values of property files.
• Edit values of XML text nodes and attributes.
• No knowledge of XML needed to edit XML files.
• Update JAR and WAR files without having to extract them.
• Update JAR and WAR files within an EAR file (or other JAR compliant archive containing JAR, WAR, SAR and other archives) without the need of extracting anything.
• Configurable temporary extraction path and type of files that should be scanned for (XML and/or Property files).

PrEd has been developed using Sun Java 1.4.0.2, Eclipse 3.0, Thinlets and Apache's Xerces-J XML parser implementation.
