Constructor Detail

JSPhandler.ClassEntry

JSPhandler.ClassEntry(JSPhandler jh,
                      java.lang.String jarName,
                      java.lang.String jarURL)
                throws JSPloaderException

Constructor.

• get JAR remote location from remoteLocations.
• Creates JSPloader.
• Instanciates a servletObjects target cache.

Method Detail

getResource

public java.net.URL getResource(java.lang.String str)

HttpContext getResource.

Specified by:

getResource in interface org.osgi.service.http.HttpContext

---

getMimeType

public java.lang.String getMimeType(java.lang.String str)

HttpContext getMimeType. In most cases, better to return null. Could return "text/html".

Specified by:

getMimeType in interface org.osgi.service.http.HttpContext

---

handleSecurity

public boolean handleSecurity(javax.servlet.http.HttpServletRequest req,
                              javax.servlet.http.HttpServletResponse res)

Handle security for a request. HttpService calls this method prior to servicing a request.

Specified by:

handleSecurity in interface org.osgi.service.http.HttpContext

---

challenge

private final void challenge(javax.servlet.http.HttpServletRequest req,
                             javax.servlet.http.HttpServletResponse res)

Service method invoked by handleSecurity.

---

isServlet

private final boolean isServlet(java.lang.Class cl)

Checks if a class implements Servlet. Recursive invocation.

---

buildServlets

private void buildServlets()
                    throws JSPloaderException

Creates servlets found in the archive and registers them. Invoked in constructor and update methods. To select classes to instanciate, uses reflection and scans the inheritence hierarchy for Servlet.

---

buildResources

private void buildResources()

Register resources starting with the archive name. I use a replacement to com.sun.jes.impl.http.ResourceServlet.

---

delete

final void delete()

Clears itself and class loaded stuff.

---

update

final void update(java.lang.String remoteLocation)
           throws JSPloaderException

Clears itself and class loaded stuff and recreates class loader.

1. Enumerates servletObjects target cache and destroys each target found
2. Clear references.
3. Invokes garbage collector.
4. Creates new JSPloader.
5. Instanciates a new servletObjects target cache.

---

instantiate

private javax.servlet.Servlet instantiate(java.lang.String classPath,
                                          java.lang.Class jspClass)
                                   throws JSPloaderException

Creates a servlet using JSPloader and stores it in servletObjects. In JES2 implementation, servletObjects acts as a repository of servlets to unregister.

---

finalize

protected void finalize()

to avoid loitering
