Help req for loop

Question

Hi All,
I am retriving values from database and then writing it to a file...The code for this is
String query = "SELECT Project_Master.proj_name,Project_Master.proj_desc,Project_Master.proj_location,folder_navigation.nav_name, content_document.cont_name,content_document.cont_type FROM Project_Master INNER JOIN folder_navigation ON Project_master.proj_id=folder_navigation.proj_id INNER JOIN content_document ON content_document.nav_id = folder_navigation.nav_id ";
ResultSet rs = stmt.executeQuery(query);
int maxcols = rs.getMetaData().getColumnCount();
while(rs.next())
System.out.println("proj_name::"+rs.getString("proj_name"));
System.out.println("proj_desc::"+rs.getString("proj_desc"));
System.out.println("proj_location::"+rs.getString("proj_location"));
System.out.println("nav_name::"+rs.getString("nav_name"));
System.out.println("cont_name::"+rs.getString("cont_name"));
for(int i =1;i <=maxcols;i++)
myData.add(new Tags_Define(rs.getString("proj_name"),rs.getString("proj_desc"),rs.getString("proj_location")));
I get output of this as
<name>data1</name>
<desc>data2</desc>
<path>data3</path>
this data is repeated 6 times as there are 6 colomns in my table
If i comment out for loop i get the above data 2 times
But I want data to be retained row wise
What should i do?
Please help
Thanks in advance

First of all, when posting code, click the code button.
Is the for loop meant to be nested in the while or is it supposed to come after it? It is impossible to tell as you did not include the closing brace.
Also this code:
String query = "SELECT Project_Master.proj_name,Project_Master.proj_desc,Project_Master.proj_location,folder_navigation.nav_name, content_document.cont_name,content_document.cont_type FROM Project_Master INNER JOIN folder_navigation ON Project_master.proj_id=folder_navigation.proj_id INNER JOIN content_document ON content_document.nav_id = folder_navigation.nav_id ";is much longer than it needs to be. Are you sure it executes without errors? Why don't you use a table alias instead?
String query = "SELECT PM.proj_name,PM.proj_desc,PM.proj_location,folder_navigation.nav_name, content_document.cont_name,content_document.cont_type
FROM Project_Master PM INNER JOIN folder_navigation ON PM.proj_id=folder_navigation.proj_id INNER JOIN content_document ON content_document.nav_id = folder_navigation.nav_id ";also, you have not specified folder_navigation or content_document in the from clause, I presume these are also tables? Also, what is myData? We do not see it declared anywhere.
