Hi dear,
I have been trying to read the productID from the url but it goes into an
infinite loop at point 1. I am posting the code below. Please help.
package net.astralpharma;
import java.io.*;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
import org.apache.struts2.ServletActionContext;
import java.io.BufferedReader;
import java.io.IOException;
import java.net.URL;
import java.net.URLConnection;
import java.sql.*;
import java.util.*;
import net.astralpharma.Connect;
import net.astralpharma.Product;
import net.astralpharma.Productdisplay;
public class Showprodsuppliers extends ActionSupport
{
private String productID;
private String productName;
List<Supplier> supplierName = new ArrayList<Supplier>();
public String execute() throws Exception{
StringBuffer sb = new StringBuffer("http://localhost:8080/Astralpharma1/astralpharma/astralpharma/showprodsuppliers.action?productID=1";);
URL url = new URL(sb.toString());
URLConnection urlConn = url.openConnection();
urlConn.setUseCaches(true);
urlConn.setDoOutput(true);
urlConn.setDoInput(true);
System.out.println("reached point 1");
OutputStreamWriter osr = new OutputStreamWriter(urlConn.getOutputStream());
BufferedReader br = new BufferedReader(new InputStreamReader(urlConn.getInputStream()));
String tempStr;
StringBuffer buffer = new StringBuffer();
System.out.println("Reached point 2");
while((tempStr = br.readLine())!= null)
{
buffer.append(tempStr + "<br>\n");
}
br.close();
StringTokenizer st = new StringTokenizer(buffer.toString());
ArrayList<String> output = new ArrayList<String>();
System.out.println("reached point 3");
while(st.hasMoreTokens())
{
String server = st.nextToken();
try{
if(st.nextToken().contentEquals("productID"));
{
productID=st.nextToken().valueOf("productID");
System.out.println("Value of productID" + productID);
}
}
catch(Exception e)
{
System.out.println("Exception" + e.getMessage());
}
}
System.out.println("Reached point 4");
Connect connect = new Connect();
Connection con = connect.useConnection();
String query="Select suppliername from supplier_proddetails where productid=?";
PreparedStatement stat = con.prepareStatement(query);
stat.setString(1, productID);
System.out.println(stat);
ResultSet rs = stat.executeQuery();
System.out.println("rs"+ rs);
while(rs.next())
{
System.out.println("inside while");
supplierName.add(new Supplier((rs.getString("supplierName"))));
System.out.println("item added successfully");
}
return "success";
}
public List<Supplier> getSupplierName() {
return supplierName;
}
public void setSupplierName(List<Supplier> supplierName) {
this.supplierName = supplierName;
}
public String getProductID() {
return productID;
}
public void setProductID(String productID ) {
this.productID = productID ;
}
public String getProductName() {
return productName;
}
public void setProductName(String productName) {
this.productName = productName;
}
}
My front end jsp is as follows:
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<title>Product Handled</title>
<link href="<s:url value="/css/main.css"/>" rel="stylesheet"
type="text/css"/>
</head>
<body>
<table class="productTable">
<tr><td>This Page Gives the List of Products handled by Astral
Pharmaceuticals</td></tr>
<tr><td>Products Handled</td></tr>
<s:iterator value="productDetail" >
<tr><td><a href="showprodsuppliers.action?productID=<s:property
value="productID"/>">
<s:property value="productName"/>
</a></td></tr>
</s:iterator>
</table>
</body>
</html>
The url i am generating is as follows:
http://localhost:8080/Astralpharma1/astralpharma/astralpharma/showprodsuppliers.action?productID=1
I just need to get the productID from the url.
Sincerely,
Prashant Singh
