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/..
As page layout, choose AbstractPageWithTable 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
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/..
Please add the following three columns to that table:
CompanyNrColumn Type: Long Column Name: Do not fill because column represents primary key and therefore is hidden Class name: CompanyNrColumn
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
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.
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 getCompanyTablePageData 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 CompanyTablePageData getCompanyTablePageData() throws ProcessingException { CompanyTablePageData pageData = new CompanyTablePageData(); SQL.selectInto("" + "SELECT COMPANY_NR, " + " NAME, " + " SYMBOL " + "FROM COMPANY " + "INTO :{companyNr}, " + " :{name}, " + " :{symbol} ", pageData); return pageData; } }
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 Data
to populate the company table
Implement the method as follows:
@Override protected void execLoadData(SearchFilter filter) throws ProcessingException { importPageData(SERVICES.getService(IStandardOutlineService.class).getCompanyTablePageData()); }
Finally, if you launch the application, you should see something like this:
You can continue the webservices tutorial.
