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

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

Server SOAP-Service - Java-Class (JavaBean) - EJB - NonJava -... 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

Server SOAP-Service - Java-Class (JavaBean) - EJB - NonJava -... Deployment Service deployen – – Run the admin client – Deploy ID=urn:ServerInfo Provider Class=bps.soap.service.ServerInfo Methods=greeting, getServerDate, getServerOS, getServerJDKVersion, getAllInfos
