Just tell me what are all the risks involved if my bean doesn't implement the Serializable interface?

Thanks for the reply.

My web application is running in one of the webservers. I just create a javaBean and set some values and put it in the request scope. In my JSP I just get the bean from the request scope and print the value... simple.

For this simple process whether my been need to implement the serializable interface. And what are all the risks involved if I didn't implement the Serializable interface. I heard that we need to implement serializable to avoid accessing/changing the data through the network. Is it true?

Thanks in advance.

I've a plain Java bean which I used as a model in the MVC architecture. My application is running in the remote server. In this situation whether my model should implement the Serializable Interface. If yes, what will be a error/exception if I failed to implement a Serializable interface?

Welcome to Javaranch

The content of the collection will not change with respect to the retrieval, You can get the elements of the collection based on the position(in case of List) any any time.

In between the two DB interactions you can close the resultset but not the statement object .

But it is not advisable to close the resultset and statement objects within try block.
you can try the below code:

finally{
if(rs!=null)
rs.close();
if(stmt!=null)
stmt.close();
}
