Web Services Assignment Help

UPDATED NOV. 22

A student found a way to get the zip code web service to work. He downloaded the latest version of JBoss 4.0.3sp1. Go ahead and download and set up the new version of JBoss, remember to deploy your axis.war file (make sure to the get the updated Axis 1.3). Also, go through the EJB 3 instructions to install the EJB 3.0 files. This shouldn't be too much work.

The best way to download files directly onto your UML is to use wget. For example:
wget http://voxel.dl.sourceforge.net/sourceforge/
    jboss/jboss-4.0.3SP1.tar.gz

We have found there are a couple of things you have to do to make sure that you can access and use the zip code web service.

  • Shutdown JBoss.
  • Make sure your axis.war from the Server Setup assignment is deployed properly. In the Server Setup assignment you deployed it to the default deploy directory, you need to deploy it to the all directory.
  • Create a jar file that contains all the classes created from the Web service. I called mine zipcodes.jar
  • Copy that zipcodes.jar to the $JBOSS_HOME/server/all/lib/ directory.
  • Change your build.xml file so that it puts that jar file in your classpath. Also, add to your build.xml file some lines that will copy the zipcodes.jar to your build/jar directory.
  • Next you'll need to edit the file $JBOSS_HOME/server/all/deploy/jbossweb-tomcat55.sar/
        META-INF/jboss-service.xml.
    Find the UseJBossWebLoader tag and change the false to true.
  • Restart JBoss.

After doing those things you should be able to get the service to work. At least that's how I got it to work.

UPDATE 11/22

There have been some problems that have arisen. It seems that for some people their WSDL2Java does not produce all the .java files you need. We found if you updated to Axis 1.3 then you should be able to generate all the .java files. After you run WSDL2Java, you should have 14 classes in the directory it creates.

Java Beans

I have found that many of you are trying to stuff you JSP pages full of code. You should be putting as much code as possible in your Session and Entity beans. You should only put code in your JSP if it is absolutely necissary.
