Create Liferay MVC Portlet
Follow the wizard to create Liferay portlet. Remember to check “create portlet class”.
Step 1) Create new Liferay portlet project
Use wizard to create new Liferay Portlet project. Make sure to choose Advanced project configuration… options on the first page and check Axis2:
Wizard creates the following project structure:
Step 2) Edit Java class
Sample Java class:
package accountList.liferay.hp.com;
import java.io.IOException;
import javax.portlet.PortletException;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;
import com.liferay.util.bridges.mvc.MVCPortlet;
/**
* Portlet implementation class AccountList
*/
public
class AccountList extends MVCPortlet {
/**
* @see MVCPortlet#MVCPortlet()
*/
public AccountList() {
super();
}
@Override
public
void doView(RenderRequest renderRequest, RenderResponse renderResponse)
throws IOException, PortletException {
String[] array = new String[] { “1”, “2”, “3” };
renderRequest.setAttribute(“myTable”, array);
super.doView(renderRequest, renderResponse);
}
}
Step 3) Edit JSP and configuration files
Add JSTL2 taglib
Add the following definitions to your JSP file
<%@ taglib uri=”http://java.sun.com/jsp/jstl/core” prefix=”c” %>
<%@ taglib uri=”http://java.sun.com/jsp/jstl/fmt” prefix=”fmt” %>
<%@ taglib uri=”http://java.sun.com/jsp/jstl/functions” prefix=”fn” %>
<%@ taglib uri=”http://java.sun.com/jsp/jstl/sql” prefix=”sql” %>
<%@ taglib uri=”http://java.sun.com/jsp/jstl/xml” prefix=”x” %>
Edit web.xml
Add the following references to \liferay-portal-6.0.6\tomcat-6.0.29\webapps\ROOT\WEB-INF\web.xml file. Check whether those references do not exist yet.
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri>
<taglib-location>/WEB-INF/tld/c.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/fmt</taglib-uri>
<taglib-location>/WEB-INF/tld/fmt.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/functions</taglib-uri>
<taglib-location>/WEB-INF/tld/fn.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/sql</taglib-uri>
<taglib-location>/WEB-INF/tld/sql.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/xml</taglib-uri>
<taglib-location>/WEB-INF/tld/x.tld</taglib-location>
</taglib>
Edit liferay-plugin-package.properties
This reference must be included in local file in the project.
portal-dependency-jars=jstl-api.jar,jstl-impl.jar
Add web service to your portlet (method 1)
Step 1) prepare and validate WSDL
I use SOAP-UI to validate WSDL. If SOAP-UI is able to generate project based on WSDL, hence the file and surrounding schemas are OK. Once validated OK, copy WSDL and surrounding XSD files to your project, e.g. into newly created \wsclient folder.
Step 2) generate client stub
Right-click on WSDL and select Web Services > Generate Client
Step 3) move generated sources
Move generated sources from /src to /docroot/WEB-INF/src directory
Step 4) Create and move JAR for XMLBeans
Axis2 is creating XMLBeans in \resources directory. In order to make them available to the run-time, do the following:
- Zip schemaorg_apache_xmlbeans
- Rename Zip to Jar
- Move schemaorg_apache_xmlbeans.jar to \docroot\WEB-INF\lib\ directory
After deployment, file will be available to the run-time environment.
Step 5) Call web service
Service call is managed by the following code in the portlet class:
xxxx.ICSOBPortStub stub = new xxxx.ICSOBPortStub();
try {
// initialize data objects
xxxx.LogonRequestDocument logonRequestDocument = LogonRequestDocument.Factory.newInstance();
xxxx.LogonResponseDocument logonResponseDocument = null;
xxxx.LogonRequestDocument.LogonRequest logonRequest = logonRequestDocument.addNewLogonRequest();
// set request parameters
logonRequest.setUserId(“md”);
logonRequest.setPassword(“111111”);
// create request document
logonRequestDocument.setLogonRequest(logonRequest);
// execute service
logonResponseDocument = stub.logon(logonRequestDocument);
System.out.println(“Response : “ + logonResponseDocument.getLogonResponse());
} catch (java.lang.Exception e){
System.out.println(“exception occured: “ + e.toString());
}
