Java basic web page not working

I'm experienced using Classic ASP and ASP.NET but new to Eclipse and JSP.  Though very similar to Classic ASP I'm unable to get a basic example to work.  My code is a simple learning tool which is comprised of a class and method that returns a string array.  My webpage then iterates this returned object and loads a table's rows.  

The problem is that no values are ever recieved on the page.  The code always completes with empty rows.  What am I missing here?

//String array class
public class ResultLookup {

	//Class declarations

	//Class constructor
	public ResultLookup() throws SQLException, IOException
	{	
	}
	
	//Return a simulated dataset
	public String[] GetResultSet()
	{
		//Local declarations
		String[] strResultArray = new String[5];
		
		//Setup string array
		strResultArray[0] = "Sample text";
		strResultArray[1] = "A short placeholder";
		strResultArray[2] = "Slightly longer placholder";
		strResultArray[3] = "This code look just like Classic ASP";
		strResultArray[4] = "JSP the Hundia to ASP.NET's Honda";
		
		//Return result
		return strResultArray;
	}
	
}


//Web page to display my data
<table border="1">
		<tr>
			<td>
				Names
			</td>
		</tr>	
	<%
	
	try
	{
		ResultLookup objResultLookup = new ResultLookup();
		String[] strResults;
		strResults = objResultLookup.GetResultSet();

		for (int i = 0; i < strResults.length; i++)
		{
		%>
		<tr>
			<td>
			<% strResults[i].toString(); %>
			</td>
		</tr>
		<%
		}			
	}
	catch (Exception ex)
	{
		System.out.print("An TestResults.jsp error has occurred!");
		System.out.print(ex.getMessage());			
	}
	finally
	{			
	}
	%>
</table>

Try replacing

<% strResults[i].toString(); %>

Open in new window


with

<%= strResults[i].toString() %>

Open in new window

Great! This was my problem.  JSP feels just like Classic ASP scripted with C#.
