The next step is to have XDoclet process these generated files and build all of the other necessary pieces, including vendor-specific deployment descriptors. In section 14.8, a complete build incorporating Middlegen, XDoclet, compilation, and building the EJB JAR and EAR files is shown.

Figure 13-6: WER incidents bucket report. Like other feedback data, WER information is always beneficial but is critically effective when collected and analyzed during beta releases. Table 13-2 contains typical crash data for the top 10 issues found in an application. Many product teams set goals regarding WER data collected during product development. Common goals include the following: Coverage method When using the coverage method, groups target to investigate N percent (usually 50 percent) of the total hits for the application. Threshold method Groups can use the threshold method if their crash curves (one is shown in Figure 13-6) are very steep or very flat. With flat or steep crash curves, using the previously described coverage method can be inappropriate because it can require too many or too few buckets to be investigated. A reasonable percentage of total hits for the threshold method is

Middlegen in practice Middlegen is still in its infancy and has a few notable issues that may preclude out-ofthe-box use: It is geared to EJB 20, so it does not generate EJB 1x-compliant code At the time of writing, only WebLogic and JBoss vendor-specific tags are being generated, although this will change quickly We ran into issues with JDBC drivers and were unable to use Hypersonic SQL and Microsoft Access3 Middlegen was unable to determine the table relationships with those databases Some JDBC metadata calls that Middlegen uses are unsupported by at least a few drivers We finally got our example relationships working against Microsoft SQL Server 2000.

Even if Middlegen does not work out of the box for a particular database or EJB container vendor, the time invested in tweaking Middlegen s freely available source code or XDoclet entity bean template is likely to be well spent The combination of Middlegen and XDoclet is a great benefit to EJB developers There are many database EJB reverse-engineering tools available, but the open-source and easily tweakable nature of these two products make them very attractive The community support available is unlikely to be matched by any commercial product vendors It s quite common for developers to write their own code generators, but it might just be time to roll up your sleeves and contribute to efforts such as Middlegen instead! To use Middlegen effectively, we recommend that you explore its capabilities gradually, starting with a few tables in a simple database.
