Hello,
When I run the 'Add shopping cart' and Vote in the Online book store application, I get this error message. May I ask if somebody can help me fix this problem ?. The rest of the application is working fine.
Regards
Gayatri

Your error was here:
org.apache.jsp.BookDetail_jsp.Rating_Show(BookDetail_jsp.java:1219)
It will trying convert string "" to Integer:
java.lang.NumberFormatException: For input string: ""
java.lang.Integer.parseInt(Integer.java:497)

What is Rating in your page?
Have custom code?
Have some control with Integer value and recover string from database?
May I ask if you cann tell me more information?

Thanks for your reply. I am trying to use the custom code from the application. The errror is in BookDetail.jsp. I think the problem is with the field fldrating. Its a string field and there is a parseint() function being done on this field. I tried converting the variable to integer but it still does not work. I do not know how to give you a copy of the code. If you have an email address, I can mail you the code.
Regards
Gayatri

Before convert to int the string field, verify if wasn't null or empty.
Use Codecharge function
if (!StringUtils.isEmpty(yourcontrol)){
/* your conversion */
}
