Steps to Reproduce Behavior

In Visual J++, select New Project from the File menu.

In the New Project dialog box, click the New tab.

In the Visual J++ Projects tree, click Web Pages.

Click Code-Behind HTML.

Click Open to create the project.

Modify Class1.java as follows:


import com.ms.wfc.html.*;
import com.ms.wfc.core.*;
import com.ms.wfc.ui.*;
public class Class1 extends DhDocument
{
   public Class1()
   {
      initForm();
   }
   private void initForm() {
   }
   protected void onDocumentLoad(Object sender, Event event)
   {
      DhElement el = this.findElement("coloredText");
      try
      {
         this.newLine();
         this.addText("ForeColor:"+el.getForeColor().toString());
      }
      catch(Exception e1)
      {
         this.newLine();
         this.addText(e.toString());
      }
      try
      {
         el.setForeColor(Color.BLUE);
         this.newLine();
         this.addText("ForeColor:"+el.getForeColor().toString());
      }
      catch(Exception e2)
      {
         this.newLine();
         this.addText(e.toString());
      }
   }
}

Modify Page1.html as follows:


<HTML>
<BODY>
<hr>
<OBJECT classid="java:com.ms.wfc.html.DhModule"
    height=0 width=0 ... VIEWASTEXT>
<PARAM NAME=__CODECLASS VALUE=Class1>
<PARAM NAME=CABBASE VALUE=Project1.CAB>
</OBJECT>
<!-- Insert HTML here -->
