Liferay update service 

Liferay book

===============================================================

7. Exposing the method as a web service

===============================================================

7.1 update service.xml

----------------------

specify remote-service="true" (default)

difference between local service and remote service.

Needless to say, once you do any modifications to service.xml file, please run "ant build-service"

7.2 updating service layer class - 2

------------------------------------

(file location - ext\ext-impl\src\com\ext\portlet\library\service\impl\BookServiceImpl.java)

public Book create(String title)

throws PortalException, SystemException, RemoteException {

return bookLocalService.create(title, "abcd");

}

(insert the additional import statements required to compile this class,)

import com.ext.portlet.library.model.Book;

import java.rmi.RemoteException;

import com.liferay.portal.PortalException;

import com.liferay.portal.SystemException;

Important: Dont forget to re-generate the service layer after inserting this method into BookServiceImpl.java

7.3 steps to expose as a web-service

------------------------------------

a. go to "/ext/ext-impl"

b. execute "ant build-wsdd -Dservice.file=src/com/ext/portlet/library/service.xml"

c. make sure the build is successful

d. from ext level run "ant deploy"

e. re-start the server

f. check the url http://localhost:7070/tunnel-web/axis

if you have error you can try http://localhost:8080/tunnel-web/axis 0r http://27.0.0.1:7070/tunnel-web/axis

g. make sure our new web-service is listed out and hence exposed.

h. in subsequent sessions we'll see how to consume this web-service from any other application.

Excercise:

Expose the getAllBooks method as a web service.
