1 Tutorial - How to Use Lotus Domino Web Services in Java Development This tutorial contains detailed information about how can we use Lotus Domino Web Services (using Web Services Provider) in Java Development. Using this sample application, we ll able to do full-text search in the Domino Directory using Web Services (Provider) technology. Just we ll need to enter search keyword and click to Search button. That s all. Let's start our sample application. Part 1 (Domino WebService) In this part of tutorial will use following Development IDE & Tools. Lotus Domino Server 8.5 Lotus Notes & Designer Now we will create Lotus Notes Application to begin our tutorial. In the application (a.k.a. notes database) we ll create new Web Services Provider design element. BlackBerry application invoke this web services and gets the results. Create new Lotus Notes Application using following information : Title : Search People Application File Name : searchpeople.nsf Add anonymous entry to ACL with Author & Create Document property. Also you can create your application any where in your server data directory. Web Services URL seems like that : db file path>/<web service name>?wsdl Picture 1 - Create Database

2 Create Web Services Provider design element using following information : Open your application in Domino Designer Expand Code \ Web Service Providers Click to New Web Service Provider button. Name : SearchPeople Type : LotusScript Click to OK Picture 2 - Domino Designer IDE - Web Service Providers Picture 3 - New Web Service Provider (SearchPeople) Picture 4 - Web Service Properties

3 Create Web Services Provider design element using following information : Tab : Basics o Name : SearchPeople o PortType Class : SearchPeople Tab : Advance o Options \ Programming model : RPC o SOAP Message Format : Doc/literal o Include operation name in SOAP action : Checked o Port type name : SearchPeople o Service element name : SearchPeopleService o Service port name : Domino Add following codes to the Declarations event of Web Service. %REM ############################################################ WEB SERVICES : SearchPeople DEVELOPER : Ferhat BULUT WEB SITE : ferhat@bestcoder.net CREATED DATE : JANUARY 13, 2010 MODIFIED DATE : DECEMBER 28, 2010 COMMENTS Bu WebService BestCoder.NET sitesinde yayınlanmak üzere blackberry mobil uygulama geliştirme örneği için hazırlanmıştır. ############################################################ %END REM REM Declaration of global variables accessible from all parts of the Web service.

5 End Class Save and close. Our webservice is ready. But don t forget to check the values of some field on your Lotus Domino server configuration document as following : Check Http task is running. HTTP Task have to be running to browse web service on the browser. Just type tell http status keywords on the server console and press the ENTER. You will see "HTTP Server Listen for connect requests on TCP Port:80" in the list if HTTP Task is running. If not, type load httpkeywords and press the ENTER. Or ask your domino administrator. Add Signer of Web Service to TAB : Security >>> PARTS : Programmability Restrictions \ Sign or run unrestricted methods and operations field. TAB : Internet Protocols \ SUB-TAB : Domino Web Engine \ Web Agents and Web Services \ Run web agents and web services concurrently? : Enabled Give an integer value to Internet Protocols \ Domino Web Engine \ Web Agents and Web Services \ Web agent and web services timeout field. Maybe 60 seconds Lets check our Web Service is running? Open your Internet Explorer or any Browser. Write to Address field. o computer ip or host name>/<db file path>/peoplesearch?wsdl and press to Enter. You will see following picture in your browser.

6 Part 2 (Stub Generator & Introduction to Eclipse) In this part of tutorial will use following Development IDE & Tools. Lotus Domino Lotus Domino Designer BlackBerry Java Plug-in for Eclipse v1.1.2 (With this version, you have to download OS plugins (4.5.0 or etc) from Available Software Sites screen using (Download) BlackBerry and MDS Services Simulator Package v4.1.4 (Download) Sun Java (TM) Wireless Toolkit 2.5.2_01 for CLDC (formerly known as J2ME Wireless Toolkit) (Download) Note : Sun Java (TM) Wireless Toolkit 2.5.2_01 for CLDC is 32-bit application. So Java (JDK) on your computer have to be 32-bit. I had a problem during stub generation process with Sun Java (TM) Wireless Toolkit (32-bit)and JDK (64-bit). Check your webservice is running. Type the Web Service url to address field. Webservice url seems like that : computer ip or host name>/<db file path>/peoplesearch?wsdl and press to Enter. Open the Sun Java Wireless Toolkit application using Utilities link. Picture 6 - Utilities > Stub Generator Select Stub Generator and click to Launch button.

7 Picture 7 - Run Stub Generator Enter necessary information in Stub Generator Dialog screen. WSDL Filename or URL : Your WSDL URL > db file path>/<web service name>?wsdl Output Path : Location for generated files. Select a directory. For example : C:\SearchPeople Output Package : Type the package name for your java files. For example : com.blackberry.lotus CLDC Version : Select CLDC 1.1 option. Select OK button to finish process. If you got an error, please check this list to solve problem : Check the Lotus Domino server is running Check HTTP Task is running o Type on console show tasks. On the list HTTP Server Listen for connect requests on TCP Port : 80 o Check server configuration (I mentioned about in Part I) o Check Web Service Provider codes o Check Java configurations (JDK have to be installed etc.) If everything is fine, Stub Generator shows a dialogbox like this. Stub Generation Complete After that close Stub Generator application. Goto C:\SearchPeople directory. Look at files. You will see 8 files. You need these *.java files to begin BlackBerry Java Application Development part of the tutorial.
