Hi Everyone,
Recently i have been trying to integrate GWT (Goolge WebToolkit) and Liferay, and i have succeeded in achieving that. I extended the GWT to now include server side call ups using RPC and i ran into some difficulties, the problem is that the portlet created by Liferay SDK creates a web.xml file that looks like this:
<web-app>
<display-name>gwt-portlet</display-name>
<listener>
<listener-class>com.liferay.portal.kernel.servlet.PortletContextListener</listener-class>
</listener>
<servlet>
<servlet-name>gwtportlet</servlet-name>
<servlet-class>com.liferay.portal.kernel.servlet.PortletServlet</servlet-class>
<init-param>
<param-name>portlet-class</param-name>
<param-value>com.sample.jsp.portlet.JSPPortlet</param-value>
</init-param>
<load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>gwtportlet</servlet-name>
<url-pattern>
/gwtportlet/*</url-pattern>
</servlet-mapping>
<taglib>
<taglib-uri>http://java.sun.com/portlet</taglib-uri>
<taglib-location>/WEB-INF/tld/liferay-portlet.tld</taglib-location>
</taglib>
</web-app>
Note the url-pattern tag where there is a back slash to the context.
and my own GWT url-pattern is "/bbtservice" defined in the GWT's module's xml file. When my GWT makes a call to the server instead of passing "http://localhost:8080/gwtliferay/bbtservice", it passes "http://localhost:8080/gwtliferay//bbtservice" (note the double slash) and this doesn't resolve to my server implementation class.
My question then is, has anybody encountered such a problem or can anyone please tell me how to make Liferay resolve the URL as i want it ("http://localhost:8080/gwtliferay/bbtservice").
NB: If i can fix this i would be publishing the steps i took for the integration on this forum. Thanks for your help.
Nnamdi.
