WSS4J Tutorial Revisit

While reading the WSS4J - Axis Deployment Tutorial I found it somewhat lacking. Also in later versions of Axis it seems that the StockQuoteService has been changed.

So here is a reworked version.

Prerequisties

Apache Tomcat 6.0.14
Axis 1.4
WSS4J 1.5.9
XML Security 1.4.3

This tutorial was performed on a Linux machine with Java 1.6.0_01-b06. ## Installing WSS4J

Install Apache Tomcat
Unpack the Apache Tomcat archive. Below this folder will be called $CATALINA_HOME
Make sure the environment variable $JAVA_HOME is set correctly.
Install Axis
Unpack the Axis archive
Copy the axis folder from webapps into $CATALINA_HOME/webapps
Install WSS4J and XML Security
Unpack the WSS4J archive and copy wss4j.jar into $CATALINA_HOME/axis/WEB-INF/lib
Unpack the XML Security archive and copy xmlsec-1.4.3.jar into $CATALINA_HOME/axis/WEB-INF/lib renaming it to xmlsec.jar
Start up Apache Tomcat by running the startup.sh command in $CATALINA_HOME/bin
Verify the installation by accessing the Axis Happiness Page. It should now list the XML Security API under Optional Components.

Creating and deploying the initial service

This tutorial will reuse the StockQuoteService that ships in the Axis sample folder. However this service tries to look up a real stock quote from a external service, located at services.xmethods.net, that doesn’t exists any more. This means that the only symbol we can look up a quote for is XXX.

Compiling and deploying the sample

Go to the unpacked Axis folder and in under samples/stock.

Compile all code using ant. The out put folder is under the Axis folder build/classes.

~axis-1_4/samples/stock$ ant

setenv:

copy:

compile:
    [javac] Compiling 6 source files to ~/axis-1_4/build/classes

BUILD SUCCESSFUL
Total time: 1 second

To deploy the sample service first copy the class files to $CATALINA_HOME/webapps/axis/WEB-INF/classes/

1
~axis-1_4/samples/stock$ cp -r ../../build/classes/samples $CATALINA_HOME/webapps/axis/WEB-INF/classes

Then edit the template deploy.wsdd to match the one below.

Now deploy using Axis Admin Client.
