# WPortlet

Simple framework to build portlets like a webapp.

## Example

```java

import javax.portlet.*;

import org.dew.portlet.*;

public 

class HelloAction implements IAction 

{

  public

  Object action(String sAction, Parameters parameters, ActionRequest request, ActionResponse response)

    throws Exception

  {

    if(parameters.isBlank("name")) {

      throw new Exception(ResourcesMgr.getMessage(request, "error.name"));

    }

    

    String sName = parameters.getString("name");

    

    return sName;

  }

  

  public

  String view(String sAction, Parameters parameters, Object actionResult, RenderRequest request, RenderResponse response)

    throws Exception

  {

    String sName = (String) actionResult;

    

    String sHello = ResourcesMgr.getMessage(request, "hello", sName);

    

    request.setAttribute("hello", sHello);

    

    return "hello.jsp";

  }

  

  public String exception(String sAction, Parameters parameters, Exception actionException, RenderRequest request, RenderResponse response)

    throws Exception

  {

    return null;

  }

}

```

## Setting Up JNDI in Liferay 7.4

In liferay/tomcat/conf/Catalina/localhost/ROOT.xml

```xml

    

```

In 7.4 Liferay introduced the "Shielded Class Loader" in an effort to shield the webapp class loader from the OSGi container.

Before invoking the lookup:

```java

Thread thread = Thread.currentThread();

// Get the thread's class loader. You'll reinstate it after using

// the data source you look up using JNDI

ClassLoader origLoader = thread.getContextClassLoader();

// get the shielded class loader

ClassLoader shieldedClassLoader = PortalClassLoaderUtil.getClassLoader();

// get the webapp class loader from it

ClassLoader webappClassLoader = shieldedClassLoader.getClass().getClassLoader();

// Set webapp class loader on the thread

thread.setContextClassLoader(webappClassLoader);

```

## Build
