Web Services using Java 6

Question

Hi,
Well, I've been very enthusiastic in implementing a new application that's taking advantage of the newly introduced technology that Java 6 has to offer, instant web services that is. I've implemented the web services and was also able to launch the internal server that comes with the JDK. I must admit that life became really easy due to those introduced technologies, it saved me a lot of time. Furthermore, now I've reached a point where an application I'm integrating with needs to call my server by invoking a simple http request, however, since my server only provides web services I'm kind of stuck and can't think of an easy (fast) solution... I wouldn't like returning to the frustrating old days where I had to use Tomcat and also Axis in order to support both of these functionalities... the question is whether there is a simple way to also expose a simple servlet by using the internal Java 6 server or maybe there is a way to expose a webservice that is actually a servlet...
your answers are very appreciated :)
thanks,
Gil.

Answer 1

Hi,
well, I've taken your advice seriously and immediately turned into embedding Jetty into my application...
However, due to the fact that I'm a newbie to both Jetty and Web Services I have gotten to a point where I no longer manage to continue :-(
In order to enable web services I've followed this guideline ([http://gorik.wordpress.com/2008/03/15/jax-ws-and-jetty/]), however, it seems to mislead in some points or at least lacks some vital information I suppose...
I could not successfully access my webservice even after doing the following actions:
1 - Writing web service source code and using webservice annotations.
2 - Successfully generating wsdl and xsd files
3 - Successfully running Jetty server
4 - created folders under jetty\webapps\ : myApplication\WEB-INF, myApplication\wsdl
5 - copied jar file holding the webservice into WEB-INF lib, copied the wsdl under the wsdl lib
6 - created a web.xml file under myApplication with the following content:
<web-app version="2.4? mlns="http://java.sun.com/xml/ns/j2ee" xsi:schemalocation="http://java.sun.com/xml/ns/j2ee [http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd]">
<description>fromwsdl</description>
<display-name>fromwsdl</display-name></web-app>
<listener>
<listener-class>com.sun.xml.ws.transport.http.servlet.WSServletContextListener</listener-class></listener> <servlet>
<description>JAX-WS endpoint - fromwsdl</description>
<display-name>fromwsdl</display-name>
<servlet-name>WebServices</servlet-name>
<servlet-class>com.sun.xml.ws.transport.http.servlet.WSServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>WebServices</servlet-name>
<url-pattern>/NadlanWebServices</url-pattern>
</servlet-mapping>
<session-config>
<session-timeout>60</session-timeout>
</session-config>
{code}
and what happens when I launch Jetty server is that it claims that it cannot find index.jsp file which is the file that's configured in jetty/etc/webdefault.xml,
though clearly, it should have not looked for this file due to the servlet mapping I've configured in the web.xml that appears above...
please help ....
thanks,
