Edit User Defined Data Source Dialog

The Edit User Defined Data Source dialog appears when you right-click a user data source and select Edit User Defined Data Source from the shortcut menu in the Catalog Manager. It helps you to edit a UDS that you have added to a catalog. See the dialog.

The following are details about options in the dialog:

Name

Specifies the name of the UDS. The name cannot be the same as any of the existing procedures, SQL files, HDSs, business views or queries. It also cannot be empty.

Class Name

Specifies the full name (including package name) of the class represented by the UDS. The jar file containing the class should be appended to the ADDCLASSPATH variable in the setenv.bat/setenv.sh file in the <install_root>/bin folder in both Logi JReport Designer and Logi JReport Server.

The class implements

After filling in the Class Name field, the class name of the interface that the class implements will be displayed here.

Parameter

Specifies the parameter string for the UDS. The parameter string must match the format defined in the UDS class. You can use parameters predefined in a Logi JReport catalog in the parameter string, and the format used in the string is "@" + parameter name. For example, if the parameter string of a UDS is SQL=select * from employee, and you want to use the parameter sql in a catalog to replace the part after "=" in the string, then the parameter string of the UDS will be SQL=@sql.

OK

Cancel
