JSP EL (Expression Language)

Purpose

• Reduce the use of scriptlets and expressions in JSP pages
• Provides cleaner, more readable syntax

Syntax

Key Uses

1. Access Scoped Objects

${scopeName.objName}

Available Scopes:

• pageScope - Page level
• requestScope - Request level
• sessionScope - Session level
• applicationScope - Application level

${sessionScope.lb.email}
${pageScope.abb.books}

2. Auto Search Mechanism

• EL automatically searches from lowest to highest scope
• Order: pageScope → requestScope → sessionScope → applicationScope
