Scout/Tutorial/3.8/webservices/Create Company Table Page
The Scout documentation has been moved to https://eclipsescout.github.io/.

Create Company Table Page
On the client node, go to 'Desktop' | 'Outlines' | 'StandardOutline' | 'Child Pages'. Right click on the node to create a new The Scout documentation has been moved to https://eclipsescout.github.io/. [1]. As page layout, choose AbstractPageWithTable
[2] to create a page representing tabular data. On the next step, enter Company
as name for that page and choose to add this page to the StandardOutline
[3]. By clicking Finish, the page is created and attached to the StandardOutline.
Create columns
On the CompanyTablePage
node, go to 'Table' | 'Columns'. Right click on the node to create a new The Scout documentation has been moved to https://eclipsescout.github.io/. [4]. Please add the following three columns to that table:
CompanyNrColumn Type: Long Column [5] Name: Do not fill because column represents primary key and therefore is hidden Class name: CompanyNrColumn [6]
NameColumn Type: String Column Name: Name Class name: NameColumn
SymbolColumn Type: String Column Name: Symbol Class name: SymbolColumn
To not display the CompanyNr
column because of holding the primary key, go to that column in Scout SDK and uncheck Displayable
in Scout Property View [7].
To have the columns equally distributed over the available space of the table page, go to the The Scout documentation has been moved to https://eclipsescout.github.io/. node and check Auto Resize Columns
in Scout Property View [8].
Create service to load company data from database
Now we have to populate the table with company data. For that purpose, double click on the StandardOutlineService
under 'Server' | 'Outline Services' to open the corresponding Java class. In there, create the operation getCompanyTableData
to load company data from database. Also add the operation signature to the service interface IStandardOutlineService
to be accessible from client side. To find the interface IStandardOutlineService, press Ctrl+Shift+T, type IStandardOutlineService and click 'Open'.
public class StandardOutlineService extends AbstractService implements IStandardOutlineService { @Override public Object[][] getCompanyTableData() throws ProcessingException { return SQL.select("" + "SELECT COMPANY_NR, " + " NAME, " + " SYMBOL " + "FROM COMPANY "); } }
Load company data into CompanyTablePage
Now as the StandardOutlineService
is ready to load company data from the database, go back to the CompanyTablePage
to consume the service's data.
On the Scout Property View, click on the operation Exec Load Table Data
to populate the company table [9]. Implement the method as follows:
@Override protected Object[][] execLoadTableData(SearchFilter filter) throws ProcessingException { return SERVICES.getService(IStandardOutlineService.class).getCompanyTableData(); }
Finally, if you launch the application, you should see something like this:
