ClassCastException

I'm trying to send multiple textarea values from jsp to be inserted into database. However the textarea values are not received in the Action class properly. I get ClassCastException when trying to insert the data into database.

Whats the workaround ?

Please see the file attached for details

It looks like you are trying to cast array of Strings into String. Try casting to Stirng[].

[javac] ps.setString(3,cvo.getItemDescription().get(k));

Where you call this:

(String)cvo.getItemDescription()

Open in new window

You should actually call:

((String[])cvo.getItemDescription())[i]

Open in new window

where i is the index of your text item.

object is right . That works . Awesome!

I just put the generic as object suggested and the error vanished....excellent.

But why the explicit casting did not work ? Why the generic worked but explicit cast failed ?

I'm using jdk 1.6 .

because it wasn't a list of strings.
Without the generics it cannot accurately determine what the type of object in the list is
