GenericPortlet - how to get an ApplicationContext.

[john green bowe, modifié il y a 16 années.]

Hi

I'am trying to create a simple liferay portlet.
I've defined some Spring beans in WEB-INF\applicationContext.xml file.

The processAction method of my ExampleGenericPortlet needs to acces portlet application context to get the beans defined in WEB-INF\applicationContext.xml.

However PortletContext interface doesn't offer an access to ServletContext (it hasn't getServletContext() method).
so I can't do:

PortletContext portletContext = this.getPortletContext();
ServletContext servletContext = portletContext.getServletContext();
ApplicationContext ctx = WebApplicationContextUtils
.getWebApplicationContext(servletContext);


What should I do to get an application context in liferay portlet ?


PS: I've also tried casting portletContext to PortletContextImpl (that has getServletContext() method) but it causes ClassCastException.

Hi,

try PortletApplicationContextUtils.

Try this one...

PortletContext pc = this.getPortletContext();
ApplicationContext context = PortletApplicationContextUtils.getWebApplicationContext(pc);
Service service = (Service) context.getBean("bean-name");

You may need spring-webmvc-portlet.jar file...

I'am trying to create a simple liferay portlet with spring+hibernate+JSF.
I've defined some Spring beans in WEB-INF\applicationContext-hibernate.xml file.
I have used this method to get the beans defined in WEB-INF\applicationContext-hibernate
.xml.

This is my code:

package web.common;
import javax.faces.context.FacesContext;
import javax.servlet.ServletContext;

import org.springframework.context.ApplicationContext;
Hi

import org.springframework.web.context.support.WebApplicationContextUtils;

public class ServiceFinder {


public static Object findBean(String beanName){
FacesContext context= FacesContext.getCurrentInstance();
ServletContext servletContext =
(ServletContext)context.getExternalContext().getContext();

ApplicationContext appContext = WebApplicationContextUtils.getWebApplicationContext(servletContext);

Object o =appContext.getBean(beanName);

return o;



}

}
But,I have an error:
ERROR [PortletServlet:96] javax.portlet.PortletException: org.apache.jasper.JasperException: java.lang.IllegalStateException: Il est interdit d''utiliser clear() quand la taille de tampon== 0
-I don't understand the message of error!!
Can someone help me,please?
