public void addELContextListener(ELContextListener listener)
```
    Description copied from interface: javax.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)
```
  - createELContext
```
public ELContextImpl createELContext(JspContext context)
```
  - addELResolver
```
public void addELResolver(ELResolver resolver)
                   throws java.lang.IllegalStateException
```
    Description copied from interface: javax.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: javax.servlet.jsp.JspApplicationContext
    
    Returns the JSP container's ExpressionFactory implementation for EL use.
    
    Specified by:
    
    getExpressionFactory in interface JspApplicationContext
    
    Returns:
    an ExpressionFactory implementation
