Class JspServlet
java.lang.Object
javax.servlet.GenericServlet
javax.servlet.http.HttpServlet
org.eclipse.equinox.jsp.jasper.JspServlet
-
All Implemented Interfaces:
-
Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig
-
public class JspServlet
- extends javax.servlet.http.HttpServlet
JSPServlet wraps the Apache Jasper Servlet making it appropriate for running in an OSGi environment under the Http Service.
The Jasper JSPServlet makes use of the Thread Context Classloader to support compile and runtime of JSPs and to accommodate running
in an OSGi environment, a Bundle is used to provide the similar context normally provided by the webapp.
The Jasper Servlet will search the ServletContext to find JSPs, tag library descriptors, and additional information in the web.xml
as per the JSP 2.0 specification. In addition to the ServletContext this implementation will search the bundle (but not attached
fragments) for matching resources in a manner consistent with the Http Service's notion of a resource. By using alias and bundleResourcePath the JSP lookup should be in
line with the resource mapping specified in {102.4} of the OSGi HttpService.
TLD discovery is slightly different, to clarify it occurs in one of three ways:
- declarations found in /WEB-INF/web.xml (found either on the bundleResourcePath in the bundle or in the ServletContext)
- tld files found under /WEB-INF (found either on the bundleResourcePath in the bundle or in the ServletContext)
- tld files found in jars on the Bundle-Classpath (see org.eclipse.equinox.internal.jsp.jasper.JSPClassLoader)
Other than the setting and resetting of the thread context classloader and additional resource lookups in the bundle the JSPServlet
is behaviourally consistent with the JSP 2.0 specification and regular Jasper operation.
