Supplied Library Tags (Logging)
This tag library adds support for ease of use of log4j logging from within Info*Engine tasks without the need to use scriptlets. It is important to note that this tag library is not a custom extension, but is actually natively supported by the Info*Engine task compiler.
The following tags are included in the http://www.ptc.com/infoengine/taglib/log tag library. To use these tags, you must include a taglib directive in your task similar to the following:
<%@ taglib uri="http://www.ptc.com/infoengine/taglib/log"
prefix="log" %>
The syntax for these tags assumes that you have specified the log prefix in the taglib directive. If you specify a different prefix, use the prefix you specified in place of log in the tag syntax.
