Unable to create a new instance of type 'some class'. Types cannot be instantiated without a public, no arguments constructor
I have a class with constructor and overloaded methods in it. When i try to import that class using blazeds i get an error saying
[RPC Fault faultString="Unable to create a new instance of type '开发者_如何学编程some class'." faultCode="Server.ResourceUnavailable"
faultDetail="Types cannot be instantiated without a public, no arguments constructor."]
How to import class having overloaded methods using blazeds
You must provide a "no args"-constructor. See Converting data from ActionScript to Java.
public class SomeClass
{
// no-args constructor is required for BlazeDS
public SomeClass() {}
public SomeClass(int arg) {}
}
public class SomeService
{
public Connection getConnection()
{
// implement to create or get a connection
}
public void saveSomeClass(SomeClass sc) throws SQLException
{
Connection conn = getConnection();
Statement stmt = conn.createStatement();
String sql = "INSERT INTO some_table (...) VALUES (...)";
stmt.executeUpdate(sql);
stmt.close();
}
}
