26103 - How to Override the Table Cell Renderer of the JSP TableView

Sample 26103: How to Override the Table Cell Renderer of the JSP TableView

Instructions

Build a new Web application project in SAS AppDev Studio by using the Model 2 Servlet template.
The template will generate a servlet and a JSP file, which, by default, are named Model2ExampleControllerServlet.java and Model2ExampleViewer.jsp. Replace the contents of these files with the code below.
Create a package called samples, and, in that class, create the HighlightKeywordTableCellRenderer java class by using the code provided below.
Execute the servlet on the test Tomcat server.

Tip: For help with building a Web application project and testing a Web application, see SAS Note 32218.

Code for HighlightKeywordTableCellRenderer.java


package samples;


import java.io.IOException;
import java.io.PrintWriter;

import com.sas.actionprovider.ActionList;
import com.sas.servlet.tbeans.StyleInfo;
import com.sas.servlet.tbeans.tableview.AbstractBaseTableView;
import com.sas.servlet.tbeans.tableview.html.DefaultTableCellRenderer;

public class HighlightKeywordTableCellRenderer extends DefaultTableCellRenderer {

	private String keyword;

	private String styleClass;

	public HighlightKeywordTableCellRenderer(String keyword, String styleClass) {
		super();
		this.keyword = keyword == null ? "" : keyword;
		this.styleClass = styleClass;
	}

	public void write(PrintWriter out, AbstractBaseTableView tableview,
			Object value, String name, ActionList actions) throws IOException {
		if (null != value && keyword.equalsIgnoreCase(value.toString().trim())) {
			StyleInfo s = (StyleInfo) super.getStyleInfo().clone();
			s.setClassid(styleClass);
			super.setStyleInfo(s);
		}
		super.write(out, tableview, value, name, actions);
	}

Required changes

If you did not use the default values during the generation of the project, you might need to update the following values.

The package for the servlet.
package servlets;
The servlet name.
public class Model2ExampleControllerServlet.java ...
The URL mapping for the action provider, which must match the servlet mapping for the servlet.
sas_actionProvider.setControllerURL(request.getContextPath()+ "/Model2Example");
The jsp page that the servlet forwards to.
RequestDispatcher rd = getServletContext().getRequestDispatcher("/Model2ExampleViewer.jsp");
