Production Risk
TLD Headers can reduce Production Risks
This code insight counts one violation each time a TLD header do not contains:
- the xml version,
- the xml encoding
- the DOCTYPE statement
Â
Why you should care
A tag library descriptor (TLD) file must have a header section including the definition of the XML version and the encoding format along with the appropriate DOCTYPE statement identifying the governing DTD.
For example, a JSP 1.2 TLD file must begin with:
<?xml version=”1.0″ encoding=”ISO-8859-1″ ?>
<!DOCTYPE taglib
PUBLIC “-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.2//EN”
“http://bit.ly/10lWUaT“>
Â
Business Impacts
Having more tag libraries than necessary is risky for the code. It is best to only have tag libraries that are used so that the code can be more productive.
