OutOfMemoryError

Hi, gurus,

I encountered a problem when testing a servlet.

When I run it, it gives me the following error:

java.lang.OutOfMemoryError
        at CrawlServlet.doPost(Compiled Code)
        at javax.servlet.http.HttpServlet.service(HttpServlet.java:747)
        at javax.servlet.http.HttpServlet.service(HttpServlet.java:840)
        at com.sun.web.core.ServletWrapper.handleRequest(ServletWrapper.java:140)
        at com.sun.web.core.InvokerServlet.service(InvokerServlet.java:169)
        at javax.servlet.http.HttpServlet.service(HttpServlet.java:840)
        at com.sun.web.core.ServletWrapper.handleRequest(ServletWrapper.java:140)
        at com.sun.web.core.Context.handleRequest(Context.java:375)
        at com.sun.web.server.ConnectionHandler.run(Compiled Code)

Here is the code of the servlet.

protected void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
{
String strKey = req.getParameter("txtKeyword").trim();
String strCat = req.getParameter("category").trim();
String strMatch = req.getParameter("radMatch").trim();

PrintWriter out;
String title = "KillerBiz";

// set content type and other response header fields first
res.setContentType("text/html");

// then write the data of the response
out = res.getWriter();

out.println("<HTML><HEAD><TITLE>");
out.println(title);
out.println("</TITLE></HEAD><BODY>");

out.println(readFromFile("killer1.txt")); // read from file
out.println(strKey);
out.println(readFromFile("killer2.txt"));
out.flush();

   int nCount = 3;
   for (int i=0; i<nCount; i++) {
     out.println(/* get from other place */);
     out.flush();
    }
   }

out.println(readFromFile("killer3.txt"));
out.flush();
out.close();
}

Any help would be appreciated.

Thank you in advance.
