to a category) and that the best way to represent this information is via an intermediate association class. In Hibernate, you can map the association class as an entity and map two one-to-many associations for either side. Perhaps more conveniently, you can also map a composite element class, a technique we show later. It s the purpose of this section to implement a real many-to-many entity association. Let s start with a unidirectional example. A simple unidirectional many-to-many association If you require only unidirectional navigation, the mapping is straightforward. Unidirectional many-to-many associations are essentially no more difficult than the collections of value-type instances we discussed earlier. For example, if the Category has a set of Items, you can create this mapping:

Printer management involves assigning forms to paper trays, setting separator pages, redirecting documents, and taking ownership of printers. Document management involves pausing and resuming documents, configuring notifications, and deleting documents from the print queue. Troubleshooting printers involves identifying and resolving printer problems such as offline printers, printers that are out of paper or ink, printers that are incorrectly configured, and situations in which users are not using a printer properly. You can gain access to printers for administration by using the Printers And Faxes window accessed through Control Panel. Windows XP Professional allows you to control printer usage and administration by assigning permissions.

The join table (or link table, as some developers call it) has two columns: the foreign keys of the CATEGORY and ITEM tables. The primary key is a composite of both columns. The full table structure is shown in figure 7.10. In JPA annotations, many-to-many associations are mapped with the @ManyToMany attribute:

@ManyToMany @JoinTable( name = "CATEGORY_ITEM", joinColumns = {@JoinColumn(name = "CATEGORY_ID")}, inverseJoinColumns = {@JoinColumn(name = "ITEM_ID")} ) private Set<Item> items = new HashSet<Item>();

Managing printers includes assigning forms to paper trays and setting a separator page. In addition, you can pause a printer so that it does not try to print documents while you troubleshoot or make configuration changes. If a printer is faulty, or if you add printers to your network, you might need to redirect documents to a different printer. You might also need to change which users have administrative responsibility for printers, which involves changing ownership.

If the software is not installed and the user opens a file associated with the software, does the software install Can the user remove the software by using the Get Programs control panel

Assign forms to paper trays. Set a separator page. Pause and resume a printer, and cancel all documents on a printer. Redirect documents to a different printer. Select a different print processor. Adjust print spooling settings. Take ownership of a printer.
