How to convert Integer value to String Value in JSP?


  Hi, i'm new with JavaServer Page(JSP), and i want to do some increasing number as the ID number for employee records. below is the case and problems found:

1.in the Page1.jsp
  select * from employee order by(ID) desc

if (rs!=null){
int id=getInt("ID)
int id2=id+1 //to increase a number for a new employee
print.out("New ID:"id2);
}
else
id2=10000;
}

2. in the Page2.jsp

String id=rs.getParameter("id2");
String name=rs.getParameter("Name");
"insert into employee(id, name)values(id2,'"+name"'")");

Error Message: Can't convert Integer to String

So, can you show me how to solve this problem?

Should be

"insert into employee(id, name)values(" + id + ",'"+ name + "')"

The variable is id not id2.

Use Integer.parseString method or something like this.

The getParameter takes always gets the variable as a string. So once you have the parameter as a string you can explicitly convert it into a integer by Integer.parseInt("String") and assigning this value to an integer varibale.
The better method is to use the oracle to your advantage. instead of just inserting the id convert it into a number by giving "insert into employee (id,name) values(to_number("+id+"),"+name+")";
The best method would be not to calculate the id in your application, where as create a sequence number in oracle eg:EMP_SEQ and just give EMP_SEQ.NEXTVAL in your insert statement in the place of "id" this will reduce a lot of overhead on you to keep track of the id and also makes the application simple.
Hope this answers your question.

Create Sequence number(EMP_SEQ) on employee table and write database trigger (ON INSERT - inserting a new record use sequence number EMP_SEQ.NEXTVAL).

Otherwise, rs.getParameter("id2").toString();
