Method Detail

addELContextListener

public void addELContextListener(ELContextListener listener)

Description copied from interface: jakarta.servlet.jsp.JspApplicationContext

Registers an ELContextListener that will be notified whenever a new ELContext is created.

At the very least, any ELContext instantiated will have reference to the JspContext under JspContext.class.

Specified by:

addELContextListener in interface JspApplicationContext

Parameters:

listener - The listener to add

getInstance

public static JspApplicationContextImpl getInstance(ServletContext context)

Returns the JspApplicationContextImpl singleton for the given ServletContext. Creates a new instance if one does not yet exist.

Parameters:

context - The ServletContext

Returns:

The JspApplicationContextImpl instance

createELContext

public ELContextImpl createELContext(JspContext context)

Creates an ELContext for the given JspContext.

Parameters:

context - The JspContext

Returns:

The created ELContextImpl

fireListeners

protected void fireListeners(ELContext elContext)

Notifies all registered ELContextListeners that a new ELContext has been created.

Parameters:

elContext - The newly created ELContext

addELResolver

public void addELResolver(ELResolver resolver)
                   throws java.lang.IllegalStateException

Description copied from interface: jakarta.servlet.jsp.JspApplicationContext

Adds an ELResolver to the chain of EL variable and property management within JSP pages and Tag files.

JSP has a default set of ELResolvers to chain for all EL evaluation:

• ImplicitObjectELResolver
• ELResolver instances registered with this method
• MapELResolver
• ListELResolver
• ArrayELResolver
• BeanELResolver
• ScopedAttributeELResolver

Specified by:

addELResolver in interface JspApplicationContext

Parameters:

resolver - an additional resolver

Throws:

java.lang.IllegalStateException - if called after the application's ServletContextListeners have been initialized.

getExpressionFactory

public ExpressionFactory getExpressionFactory()

Description copied from interface: jakarta.servlet.jsp.JspApplicationContext

Returns the JSP container's ExpressionFactory implementation for EL use.

Specified by:

getExpressionFactory in interface JspApplicationContext

Returns:

an ExpressionFactory implementation
