Converter de String para int

Estou tentando converter uma string para int e o código esta dando erro. Já tentei comentar tal linha da conversão, e assim o codigo se comporta corretamente.Sem dar erro algum.
Algume sabe o que pode estar de errado?

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import javax.servlet.http.HttpSession;

public class ExcluirArtigo extends HttpServlet {

Connection con=null;

ExcluirArtigoDAO cd = new ExcluirArtigoDAO();

Artigo artigo= new Artigo();

protected void processRequest(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

RequestDispatcher view;

response.setContentType(“text/html;charset=UTF-8”);

PrintWriter out = response.getWriter();

try {

String id=request.getParameter("id");
      int chave = Integer.parseInt((String) "chave");   
      artigo.setChavePrimaria(chave); 
      
      cd.excluirArtigo(artigo.getChavePrimaria());
              
      request.setAttribute("msg","Artigo excluido com sucesso");
      RequestDispatcher requestDispatcher= request.getRequestDispatcher("/prof_conteudo.jsp"); 
      requestDispatcher.forward(request, response);

}

catch(Exception e)

{

out.print(e.getMessage());

e.printStackTrace();

}

}
