JSP Tag Libraries
JSP custom tags (taglibs) allow Java programmers to add CFML-like tags to JSP
- Like Java CFX, but more powerful
- Theoretically, taglibs can eliminate Java code from JSP pages
JSP Standard Tag Library (JSTL) 1.0 released in June
- Variable creation and display (expression language)
- Flow control: conditional statements, loops
- SQL Database access
- XML processing
XML-compliance sometimes leads to awkward syntax
- JSTL can’t do <CFIF> … <CFELSEIF> … <CFELSE> … </CFIF>
- JSTL can’t do <CFIF variable EQ value>
- JSTL can’t do <CFSET variable=value>
