Reviewing the Source Code for the Report Block

Estimated completion time: 5 minutes

In Chapter 4, "Creating a Report Block for the Web Report", you added a report block to a JSP-based Web report. This chapter reviews the source code added for the report block.

5.1 View the Web source in Reports Builder

To view the Web source:

• Open the Web source for the report you created in Chapter 4, "Creating a Report Block for the Web Report" called empreva_<your initials>.jsp by double-clicking the Web Source node in the Object Navigator.

5.1.1 Review the Header tag and body

1. In the Web Source view, locate the <!-- Header --> line.

   This HTML code indicates a comment line that helps you locate the report heading information in the file.

2. Locate the <th> and <tr> tags, which should look something like this:

   <tr>
   <th <rw:id id="HBEMPLOYEEID92" asArray="no" /> 
   

   class="OraColumnHeader">Employee Id </th>
   

   <th <rw:id id="HBempname92" asArray="no" /> class="OraColumnHeader"> Emp 
   

   Name </th>
   

   ...
   

5.1.2 Review the rw:foreach tag and body

The rw:foreach tag loops across a group. The layout is repeated for each instance of the specified group.

1. In the Web Source view, locate the <rw:foreach> JSP tag and find this line:

   <rw:foreach id="R_G_EMPLOYEE_ID921" src="G_EMPLOYEE_ID">
   
   

   Here, R_G_EMPLOYEEID is a unique identifier for this loop and G_EMPLOYEE_ID is the data model group on which the loop repeats.

2. Notice that the </tbody> tag that closes the table follows the closing </rw:foreach> tag, shown here:

        <td <rw:headers id=HFDEPARTMENTID92" src...>
      </tr>
     </rw:foreach>
   </tbody>
   

5.2 Verify your JSP code

If you've gone through this chapter and still aren't sure whether your JSP is correct, open the file we've provided, called empreva.jsp. This file is located in your examples directory.

5.3 Summary

Congratulations! You have finished reviewing the source code for the report block you added in Chapter 4, "Creating a Report Block for the Web Report". Continue to Chapter 6, "Creating a Graph for the Web Report" to add a graph to your Web report.
