OVERVIEW

In these directories are two client-server pairs, one that
demonstrates Project 4's warehouse and one that 
demonstrates a tax service.  Each's usage is documented below.



TAXES

To access TaxService.jws as a web service, simply
do the following.

1.  Spawn Tomcat from within examples11/server/, after
    specifying in examples11/server/conf/server.xml the 
    ports desired.

2.  Execute the following command (which, unfortunately, wraps onto 
    a second line) from within examples11/clients/taxes/.

    java org.apache.axis.wsdl.WSDL2Java
    "http://$ICEBOX.fas.harvard.edu:n/taxes/TaxService.jws?wsdl"

3.  Edit the first line of
    examples11/clients/taxes/TaxClient.java so that
    the appropriately named package is imported.  The first line of
    that file, at present, is 

    import edu.harvard.fas.ice1.taxes.TaxService_jws.*;

    because we whipped up this demo on ice1.fas.harvard.edu.

4.  Execute the following commands from within 
    examples11/clients/taxes/.

    javac TaxClient.java
    java TaxClient 

    You should see the result of the service's performing the
    various calculations specified in TaxClient.java.


WAREHOUSE

To access Project 4's warehouse as a web service, simply
do the following.

1.  Spawn Tomcat from within examples11/server/, after
    specifying in examples11/server/conf/server.xml the 
    ports desired.

2.  In another terminal, execute the following command (which, 
    unfortunately, wraps onto a second line) from within 
    examples11/clients/warehouse/.

    java org.apache.axis.wsdl.WSDL2Java
    "http://$ICEBOX.fas.harvard.edu:n/warehouse/services/Purchasing?wsdl"

3.  Edit the first line of
    examples11/clients/warehouse/PurchasingClient.java so that
    the appropriately named package is imported.  The first line of
    that file, at present, is 

    import edu.harvard.fas.ice1.warehouse.services.Purchasing.*;

    because we whipped up this demo on ice1.fas.harvard.edu.

4.  Execute the following commands from within 
    examples11/clients/warehouse/.

    javac PurchasingClient.java
    java PurchasingClient

    You should see the result of the service's application of po-ack.xsl
    to the empty <PO/> element passed to the service by PurchasingClient.
