Java Question

fetching records from database and displaying on struts webpage

My query is how to fetch records from a database table and display it on struts webpage. I have pasted my code below. When I run this code I didn't get any error but the table is not displayed even though the table contains many records. I googled it, but couldn't find the answer. Even the SO's similar solution didn't help me.. Thanks in advance.

//POJO Class

package example;

public class SplitConfig {

private String file_id;
private String category;

public String getFile_id() {
return file_id;
}

public void setFile_id(String file_id) {
this.file_id = file_id;
}

public String getCategory() {
return category;
}

public void setCategory(String category) {
this.category = category;
}

}


//Action Class

package example;

import com.opensymphony.xwork2.ActionSupport;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.util.ArrayList;

public class SplitConfigAction extends ActionSupport {

private ArrayList<SplitConfig> list = new ArrayList<SplitConfig>();

public ArrayList<SplitConfig> getList() {
return list;
}

public void setList(ArrayList<SplitConfig> list) {
this.list = list;
}

public SplitConfigAction() {
}

public String execute() throws Exception {
try {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection con = DriverManager.getConnection("jdbc:sqlserver://192.168.100.25:1433;databaseName=db_h2h;user=sa;password=123");
PreparedStatement ps = con.prepareStatement("select * from reporttracking.dbo.FILE_MASTER");
ResultSet rs = ps.executeQuery();
while (rs.next()) {
SplitConfig sc = new SplitConfig();
sc.setFile_id(rs.getString(1));
sc.setCategory(rs.getString(2));
list.add(sc);

}
con.close();
} catch (Exception e) {
System.out.println(e.getMessage());
}
return "success";
}

}

Answer

I wrote a different class name for splitcon action... Instead of ShowSplitAction, the class should be SplitConfigAction...
