3 Web (Apache) Servlet- Container (Tomcat) - soap.war (ApacheSOAP WebApplication)

4 + ApacheSOAP Web (Apache) Servlet- Container (Tomcat) - soap.war (ApacheSOAP WebApplication) includes - Deploy-JSP's - RPC-Router-Servlet

5 Web (Apache) Servlet- Container (Tomcat) - soap.war (ApacheSOAP WebApplication) includes calls - Deploy-JSP's - RPC-Router-Servlet

6 SOAP-Client SOAP-Client - Java-Client-App sends XML-Doc via HTTP / Port 80 Web (Apache) Servlet- Container (Tomcat) - soap.war (ApacheSOAP WebApplication) includes calls Client - Deploy-JSP's - RPC-Router-Servlet

12 Deployment Tomcat-ServletContainer entpacken tar zxvf jakarta-tomcat tar.gz Apache-SOAP entpacken tar zxvf soap-bin tar.gz Environment setzen export JAVA_HOME=/usr/lib/java export CLASSPATH=~/test/jars/soap.jar: ~/test/jars/xerces.jar:~/test/jars/mail.jar:~/test/jars/activation.jar: ~/java/classes

13 Deployment Tomcat konfigurieren Context-Tag hinzufügen in../jakarta-tomcat /conf/server.xml z.b. direkt vor </Host> : <Context path="/soap" docbase="~/test/soap-2_3_1/webapps/soap" debug="1" reloadable="true"> </Context> Benötigte JARs: soap.jar, xerces.jar, mail.jar, activation.jar kopieren nach../jakarta-tomcat /common/lib/

14 Deployment Tomcat konfigurieren CLASSPATH anpassen in../jakarta-tomcat /bin/setclasspath.sh # Set standard CLASSPATH CLASSPATH= "$JAVA_HOME"/lib/tools.jar: ~/java/classes: Tomcat starten/stoppen cd../jakarta-tomcat / bin/startup.sh bin/shutdown.sh
