I am playing with Guice 2.0 and WebSphere 6.1. My servlet is
configured in Guice module.
public class ServletConfigListener extends GuiceServletContextListener
{
@Override
protected Injector getInjector() {
return Guice.createInjector(new RpcServerModule());
}
}
public class RpcServerModule extends ServletModule {
@Override
protected void configureServlets() {
serve("*.rpc").with(RpcServiceImpl.class);
}
}
And I have configured GuiceFilter and above listener in my web.xml.
<filter>
<filter-name>guiceFilter</filter-name>
<filter-class>com.google.inject.servlet.GuiceFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>guiceFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<listener>
<listener-class>
gov.ontario.mnr.irs.ServletConfigListener
</listener-class>
</listener>
However my servlet RpcServiceImpl is never called. I traced Guice and
found out in class com.google.inject.servlet.ServletDefinition, method
service(), it tries to match the servlet path with my servlet pattern:
public boolean service(ServletRequest servletRequest,
ServletResponse servletResponse) throws IOException,
ServletException {
final boolean serve = shouldServe(((HttpServletRequest)
servletRequest).getServletPath());
But the servlet path always equals to "", then the pattern is not
matched. Should Guice use request URI instead of servlet path when try
to match servlet pattern?
I worked this around by putting following lines in web.xml:
<servlet>
<servlet-name>RpcServlet</servlet-name>
<display-name>Gwt-Rpc Servlet</display-name>
<servlet-class>com.my.RpcServiceImpl</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>RpcServlet</servlet-name>
<url-pattern>*.rpc</url-pattern>
</servlet-mapping>
I don't believe this is a Guice bug, as if it is a bug, it should be
very easy to be detected. What did I do wrong? Any help is very
appreciated. Thank you.
