Item anItem = // Load an item // Delete all the referenced bids for ( Iterator<Bid> it = anItem.getBids().iterator(); it.hasNext(); ) { Bid bid = it.next(); it.remove(); session.delete(bid); } session.delete(anItem); // Finally, delete the item // Remove reference from collection // Delete it from the database

The first of these verifies that all the libraries are in place and all is well; the second forces the Axis servlet to compile the sample web service and run it The service is, of course, a version of the infamous stock option service If either URL is unreachable, you may not be running Tomcat on that port; alter the URL to point to your server If you receive the 500 error code (internal server error), it is probably because the libraries are not in the right place Failing that, check the installation guide in the Axis documents and FAQ at the Axis web site for more advice 153.

First you remove the references to the bids by iterating the collection. You delete each Bid instance in the database. Finally, the Item is deleted. Iterating and removing the references in the collection seems unnecessary; after all, you ll delete the Item at the end anyway. If you can guarantee that no other object (or

1 The simple way to build a web service Now that Axis is in place and working, let us write our simple web service, which will export the indexed search as a web service, enabling calling applications to send a search term and then get the result back as a list of URLs We will also tack in a management call to tell us the last search string submitted The easiest way to write a web service in Axis is to implement the service API as a Java class, save it with the extension jws, and copy it into the Axis web application anywhere outside the WEB-INF directory We could do that, but it is too reminiscent of the JSP problem: if the server compiles the code, bugs only show up after deployment Given that jws files are really .

row in any other table) holds a reference to these bids, you can make the deletion transitive. Hibernate (and JPA) offer a cascading option for this purpose. You can enable cascading for the delete operation:

java files, why can t we compile them in advance, just to make sure they work We can, and that s what we are going to do There are two ways to do this We could work with the jws files and then copy them to files with a java extension to test compile them However, if we do that and we find a bug, clicking on the error string in the IDE will bring up the copied file, not the jws original Java IDEs don t know that jws files are really Java source, so we would lose out on the method completion, refactoring, and reformatting that we expect from a modern IDE Clearly, the second approach save as java files and copy to jws during deployment is the only sensible one.

The operation you cascade in JPA is called remove:

public class Item { ... @OneToMany(cascade = { CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REMOVE }, mappedBy = "item") private Set<Bid> bids = new HashSet<Bid>(); ... }

Of course, we have to differentiate the service files from normal Java files, which we do by keeping them out of the src directory tree, placing them into a directory called soap instead In our build process, we have to give these files a jws extension before copying them to a web server or into a WAR file Figure 153 shows the build process..

The same code to delete an item and all its bids is reduced to the following, in Hibernate or with JPA:

Figure 15.3 Our simple web service build process. The <javac> step is only there to validate files before deployment.

Item anItem = // Load an item session.delete(anItem); entityManager.remove(anItem);

This is what our simple service looks like, with a stub implementation of our search call:
