Ok. Solved.

I declared it to be a String eariler up in the JSP page. That's why.

Below is the error.

insertOrder(int,java.lang.String,java.lang.String,long) in limited.ProcessBean2 cannot be applied to (int,java.lang.String,java.lang.String,java.lang.String)
processBean.insertOrder( uniqueOrderID, name, address, creditCardNumber);

----------------------------------------------------------------------

In ProcessBean2.java, there's a method accepting the parameters (int, String, String, long).

Does it mean that my ( uniqueOrderID, name, address, creditCardNumber) is actually (int, String, String, String)?

Hmmmm...

When I included the public infront of the empty constructor, it still couldn't work.

But when I deleted the constructor away, it's able to work again.

Oh my!! It works now!

Hi.

I have the following tags in my JSP.

<jsp:useBean id="cart" scope="session" class="limited.CartBean" />
<jsp:useBean id="idBean" scope="page" class="limited.GetOrderIDBean" />
<jsp:useBean id="databean" scope="page" class="limited.InsertDataBean" />

Only the third failed to compiled.



Nothing's looking wrong.....or is there...

I'm sorry if I posted this in the wrong forum.

Here's my problem...
I have a javaBean that writes stuff to the database to be saved.
It works fine when I use a testing Class to invoke the bean's method to write some dummy variables.

When I deployed it on a JSP page, I received the following error.

"org.apache.jasper.JasperException: /checkout.jsp(4,0) The value for the useBean class attribute limited.InsertDataBean is invalid.
"

I should think my bean met the bean requirements. But I can't find out what's wrong. Any help would be really really really great..

Here's my insertDataBean code

I have a class containing a private array. (as below)



How can I display all the items in another class by invoking the getMyArray() method?

Let's say I have a getter method.

What is the difference between a return and a return()?

Oh okay, solved. THanks to all who replied.

I had to instantiate Pack1 as an object inside Pack2.

Man, fundamentals.

Hey thanks a lot!!!

I have created a constructor to read the values into the array.

Another problem came up, though.

This file is in a package.

When I use another file to reference the array index myDouble[0] and print out using the command prompt, the result was 0.0, instead of the 21.2 I read it into the first file (Pack1.java in this case)

Here's my other file called Pack2.java

I create the simplest array and it doesn't work...

Here's the java file with the array code



It gives me the following error message..

D:\webapp_proj2\WEB-INF\classes\limited\Pack1.java:9: ']' expected
myDouble[0] = 21.2;
^
D:\webapp_proj2\WEB-INF\classes\limited\Pack1.java:9: <identifier> expected
myDouble[0] = 21.2;

I'm lost.

I've tried System.out.println in the connection file too. And the queries were printed out correctly. I have 9 items, and all the 9 items were displayed.

But somehow when I run the other java file to reference the array from the connection file, it returns null.

hmmm...

I have an array in a jdbc class file.
But I can't reference it in another class file in the same package.


Here's my jdbc connection class code



and further down (in the same file )I have



in another file called file2.java, I tried to reference the array in the above file using the following...



I've got null printed.

I don't know what I've missed...

The service method is not empty. And I've put the servlet in the correct package in the correct class.

I've also repackaged the servlet. But still doesn't work.

I got the code from a textbook's CD, so can't think of what other things that could go wrong.

Here's the code.

I noticed that sometimes my IMAGE button doesn't appear.

Is it a bug?
