I am trying to connect to a database through a servlet. I am getting the following error message:
sun.jdbc.odbc.JdbcOdbcConnection Error: 500 Location: /servlet/ProjectRequestProcessingInternal Servlet Error:java.lang.ClassCastException: sun.jdbc.odbc.JdbcOdbcConnection at ConnectionPool.returnConnection(ConnectionPool.java:180) at ProjectRequestProcessing.doPost(ProjectRequestProcessing.java:86) at javax.servlet.http.HttpServlet.service(HttpServlet.java:760) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)
I am not sure what the problem is, primarily because I don't know where the error is occuring. I have a servlet called ProjectRequestProcessing and a helper class called ConnectionPool. But I am not quite sure what the where the problem is occuring. Can any shed some light on this? Thanks in advance
Hi, I think the error is with the connection pool class. There is some problem in the casting you have done in the connection pool class. Try to solve it. Subramanian
I hope you have Your Connection Pool's Java File with you. 1) refer to its returnConnection() method and check what is on the left hand side of "DriverManager.getConnection() method". I guess the object on left side is of a class which doesn't implement Connection interface. ref: ConnectionPool.returnConnection(ConnectionPool.java:180) 2) If everything is right there, then plz check in your file where you are calling this function than that may be the place which is causing you trouble.
