How to create a POJO data set
This procedure assumes you have already created the POJO data source that this data set uses. Examples in this section refer to the POJO example in
Listing 4‑1.
1 In Data Explorer, right-click Data Sets, then choose New Data Set.
2 In New Data Set, specify the following information:
1 In Data Source Selection, select the POJO data source to use. Data Set Type displays POJO Data Set.
2 In Data Set Name, type a name for the data set.
3 Choose Next.
3 In New POJO Data Set, specify the following information:
1 In POJO Data Set Class Name, specify the POJO class that retrieves the data at run time. Choose Browse to find and select the class.
2 In Application Context Key, use the default key or delete it. This property is optional.
Figure 4‑45 shows an example of properties set for a POJO data set.

4 Choose Next.
5 Map methods or fields in a POJO class to data set columns, using the following steps:
1 In POJO Class Name, specify the POJO class that contains the get methods to map to columns. You can choose Browse to find and select the class.
The data set editor uses a get* filter to display all the get methods in the specified POJO class, as shown in
Figure 4‑46.

2 Double-click the get method to map to a data set column.
Add Column Mapping displays the mapping information, as shown in
Figure 4‑47.

Choose OK to accept the default values.
3 Repeat the previous step for every column to add to the data set.
Figure 4‑48 shows an example of column mappings defined in a POJO data set.

6 Choose Finish to save the data set. Edit Data Set displays the columns, and provides options for editing the data set.
7 Choose Preview Results to view the data rows returned by the data set.
