Risks: JSP Maintainability

• Scriptlets and declarations hurt JSP maintainability
• JSP is maintainable if it is primarily markup
• With JSP 2.0, some think scriptlets and declarations are not needed at all
• JSP book authors endorse this view
• Custom actions and the JSP expression language deemphasize scripting elements in favor of encapsulating code in other objects
• Trade-off: Custom actions are relatively heavyweight compared to embedded scripts, so scripting elements still have a place in JSP
