Problem with passing object array into Velocity context

Hello

I have problem with passing array of objects into Velocity context, or
rather with accessing fields of these objects. Here is some of my
code:

Java Servlet

class Category {
 String parent="", name="";
 int id=0;
			
 public Category(int idp, String parentp, String namep) {
  id=idp;
  name=namep;
  parent=parentp;
 }

}

Category[] categories = new Category[4];
categories[0]=new Category(10001,"Top","Ankieta");
categories[1]=new Category(10002,"Top","Badania");
categories[2]=new Category(10003,"Top","Rezultaty");
categories[3]=new Category(10004,"Top","Wydruki");
			
ctx.put("categoriesList",categories);

and Velocity template

<select name="tCategory">
#foreach( $category in $categoriesList )
	 <option VALUE="$category.id"> $category.parent >> $category.name
</OPTION>
#end
</select>

And now html output!!!

<select name="tCategory">
	 <option VALUE="$category.id"> $category.parent >> $category.name
</OPTION>
	 <option VALUE="$category.id"> $category.parent >> $category.name
</OPTION>
	 <option VALUE="$category.id"> $category.parent >> $category.name
</OPTION>
	 <option VALUE="$category.id"> $category.parent >> $category.name
</OPTION>
</SELECT>

Please help!! What am I doing wrong??

Your "Category" class doesn't have accessor methods. That won't work.

Add
   String getParent() { return parent; }
   String getName() { return name; }

and all should be fine....
