In what line? In all cases, use the debugger and find out. This is one of the simplest exceptions to locate and fix.

You are probably failing at parsing the date.

Please make that an extra line and check the format.
It's probably best to keep it to the default format:

Java

DateFormat df = new SimpleDateFormat();//"MM/dd/yyyy"); 

// otherCode();

String dateValue = ptechdatabean.getFrom_Date();
Date date = df.parse(dateValue);
cs.setDate(6, date);

Ensure that the field you're trying to get from contains a date in the format you are formatting. If the date field is null, the NullPointerException is thrown, otherwise it throws the ParseException. In your case, I think your bean is not passing the date, check your code abstraction to see where the problem really is and then try the following.

Java

DateFormat df = new SimpleDateFormat("MM/dd/yyyy");
// You don't have to cast to Date as the returned value is already formatted as a date.
cs.setDate(6, df.parse(ptechdatabean.getFrom_Date());
