Use getValues().nextLine().equals("n") instead. The Scanner name is confusing BTW, just name it scanner instead of getValues which is more appropriate for a method name.

You are comparing a Scanner object with a String object.

This doesn't seem to be a JSTL problem since the class missing belongs to the jsp-api.jar library which is a part of the standard distribution [i.e. part of the specification, placed in Tomcat/lib]....

What's wrong with the getTime() method of the Date class which returns the number of milliseconds elapsed since January 1970 as long? To get the seconds, just divide by 1000.

Just report that post using the "Flag Bad Post" option and it should get appropriately handled.

Yes, as long as it's not a space, it would work. For a more standardized naming approach, trying replacing the underscore with a hyphen.

Done and done. :-)

Read the contract of the substring method; substring(4, 6) == 2 characters.

Also get in the habit of using uppercase characters for enums i.e. `BIN' instead of `bin'.

I don't think so. :-)

Post the entire command you are using as it is.

C:\Test>java -cp .;ojdbc14.jar OracleConnect

Read my previous reply; just typing the class name won't do; you have to set the classpath.
