Method Detail

setLoadOnStartup

void setLoadOnStartup(int loadOnStartup)
Sets the loadOnStartup priority on the Servlet represented by this dynamic ServletRegistration.

A loadOnStartup value of greater than or equal to zero indicates to the container the initialization priority of the Servlet. In this case, the container must instantiate and initialize the Servlet during the initialization phase of the ServletContext, that is, after it has invoked all of the ServletContextListener objects configured for the ServletContext at their ServletContextListener#contextInitialized method.

If loadOnStartup is a negative integer, the container is free to instantiate and initialize the Servlet lazily.

The default value for loadOnStartup is -1.

A call to this method overrides any previous setting.

Parameters:
loadOnStartup - the initialization priority of the Servlet
Throws:
IllegalStateException - if the ServletContext from which this ServletRegistration was obtained has already been initialized

setServletSecurity

java.util.Set<java.lang.String> setServletSecurity(ServletSecurityElement constraint)
Sets the ServletSecurityElement to be applied to the mappings defined for this ServletRegistration.

This method applies to all mappings added to this ServletRegistration up until the point that the ServletContext from which it was obtained has been initialized.

If a URL pattern of this ServletRegistration is an exact target of a security-constraint that was established via the portable deployment descriptor, then this method does not change the security-constraint for that pattern, and the pattern will be included in the return value.

If a URL pattern of this ServletRegistration is an exact target of a security constraint that was established via the ServletSecurity annotation or a previous call to this method, then this method replaces the security constraint for that pattern.

If a URL pattern of this ServletRegistration is neither the exact target of a security constraint that was established via the ServletSecurity annotation or a previous call to this method, nor the exact target of a security-constraint in the portable deployment descriptor, then this method establishes the security constraint for that pattern from the argument ServletSecurityElement.

Parameters:
constraint - the ServletSecurityElement to be applied to the patterns mapped to this ServletRegistration
Returns:
the (possibly empty) Set of URL patterns that were already the exact target of a security-constraint that was established via the portable deployment descriptor. This method has no effect on the patterns included in the returned set
Throws:
IllegalArgumentException - if constraint is null
IllegalStateException - if the ServletContext from which this ServletRegistration was obtained has already been initialized

setMultipartConfig

void setMultipartConfig(MultipartConfigElement multipartConfig)
Sets the MultipartConfigElement to be applied to the mappings defined for this ServletRegistration. If this method is called multiple times, each successive call overrides the effects of the former.

Parameters:
multipartConfig - the MultipartConfigElement to be applied to the patterns mapped to the registration
Throws:
IllegalArgumentException - if multipartConfig is null
IllegalStateException - if the ServletContext from which this ServletRegistration was obtained has already been initialized

setRunAsRole

void setRunAsRole(java.lang.String roleName)
Sets the name of the runAs role for this ServletRegistration.

Parameters:
roleName - the name of the runAs role
Throws:
IllegalArgumentException - if roleName is null
IllegalStateException - if the ServletContext from which this ServletRegistration was obtained has already been initialized
