Hi
I am making a web page where the user will enter a number such as "010383" and page should download a file and print it.
I have made the html page and the servlet. can you please show me where i have made mistake?
CgSkew.java
package cgSkewPackage;
import java.io.*;*
*import java.net.MalformedURLException;*
*import java.net.URL;*
*import javax.servlet.*;
import javax.servlet.http.*;

public class CgSkew extends HttpServlet {
public String getCgSkew; // Stroing the user input
public String url1; // Stroing the first part of the url.
public String url2; //Storing the last part of the url.
public String getURL; // Stroing the complete url
private String docType;
public void getUserValue(HttpServletRequest request,HttpServletResponse response)
throws ServletException, IOException { {
// Getting the user input
getCgSkew = request.getParameter("cgSkew");
// Checking for null value
if ((getCgSkew == null) || (getCgSkew.trim().equals(""))){
response.sendRedirect("http://wwww.x.com/x.html");}
else {
getCgSkew = getCgSkew.trim();
calculation(getCgSkew);
}
}
}// End of public void getUserValue
public void calculation(String getCgSkew) throws IOException {
throw new UnsupportedOperationException("Not yet implemented");
url1 = "http://eutils.ncbi.nlm.nih.gov/entrez/eutils/efetch.fcgi?db=genome&id=NC_";
url2="&rettype=gb";
//Creating complete URL
getURL= url1+getCgSkew+url2;
//Opening connection to download the file.
try{
URL geneBankLink = new URL(getURL);
BufferedReader in = new BufferedReader(
new InputStreamReader(
geneBankLink.openStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
docType ="<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 " +"Transitional//EN\">\n";
out.println(docType+"<HTML>\n");
out.pritln("<TITLE>"+"</TITLE>\n");
out.println("<BODY>\n"+inputLine+"</BODY>\n");
out.println("</HTML>");
in.close();
}
catch(MalformedURLException e) {
}
}
public static void main(String args[]){
}
}Netbean is showing error in all
"out.println" statements. I am trying to print the value that is being stored. Is there any other way I can do this?
