  5. Considerations • Battery life • Memory • CPU • Bandwidth • Design

  6. SOAPSimple Object Access Protocol • Based on XML • Procedure calls on remote objects • Exchange of structured, typed informations on the Web • Support of severals protocols and internet formats (SMTP, MIME, HTTP…)

  7. SOAP • Creation of Web-services • Define elements to specify : • Method’s name • parameters • retourned type

  8. Royco minute SOAP

  9. SOAP • SOAP requests: LIEBIG <soap:Body> <ns1:login xmlns:ns1="urn:LuxdealService"> <username xsi:type="xsd:string">cedrprus</username> <password xsi:type="xsd:string">newpass</password> </ns1:login> </soap:Body>

  10. Apache SOAP • Popular : • Java • Complet API • Open source

  11. Server Tomcat • Developed by Apache (project jakarta) • HTTP Server • Servlets Container

  12. JerryMouseTomcat • Two objects : • An initialization class (servlet) • Connection to MYSQL, DB’ managing, authentification • An implementation class • Service’s method

  46. Application creation 1) Compilation 2) Preverification 3) Obfuscation 4) Jarring and JAD updating 5) Deployment

  47. Compilation • Depending on targeted device • Simple javac Wireless Tool Kit 2.1 example : Motorola example : javac -g:none -bootclasspath ..\simulators\WTK21\lib\midp20.zip;..\lib\soap -d ..\tmpclasses ..\src\luxdeal\*.java javac -target 1.1 -O -bootclasspath ..\simulators\motorolaA760\lib\midp.zip;..\lib\soap -d ..\tmpclasses -classpath ..\tmpclasses ..\src\luxdeal\*.java
