Body
Given that Spring Batch is a batch framework that does not deal with user input, I'm not sure you're working with the right scenario here. However, there are a few different options here: <ol> <li>Use a job parameter and a decision step to direct to the correct combination of ItemReader/ItemWriter. The disadvantage of this is that you would need to define a step per implementation (one to handle PDF, one for Excel, etc), however since the choice would be done only once per run of the job it would have less of an impact on performance.</li> <li>A cleaner approach would still use a job parameter, however it would use the ClassifierCompositeItemWriter to delegate to the appropriate writer. This ItemWriter would be configured with one ItemWriter delegate per implementation type (PDF, Excel, etc) and would dictate to them based upon the implementation of the Classifier interface you configure. While this is a cleaner approach from a configuration standpoint, it has the disadvantage of evaluating each of the individual items for which ItemWriter to processs (it's a disadvantage assuming that the entire run is intended to send all of the items to the same ItemWriter per run).</li> <li>Finally, I would think that you should be able to, in theory, use Spring's bean factory concepts to inject an ItemWriter when the job starts. For the record, this is purely speculation and I have not actually tried this.</li> </ol> Michael T Minella Author of <a href="http://www.apress.com/9781430234524" rel="nofollow">Pro Spring Batch</a>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
