How to pass form field values between JSP pages?
I have a JSP form, and I need to pass all the form field values between two other pages.
And one of the form field values is a textarea field.
I don't think they can be passed in the URL, because of the length restriction.
So how can I do this.
An example would be appreciated.

Use POST method in your FORM tag.
<form name="form1" action="jsp2.jsp" method="post">
<input type="text" name="field1">
<input type="text" name="field2">
<input type="text" name="field3">
<input type="text" name="field4">
<input type="text" name="field5">
...
<input type="text" name="fieldn">
<input type="submit">
</form>
<input type="text" name="field1">
<input type="text" name="field2">
<input type="text" name="field3">
<input type="text" name="field4">
<input type="text" name="field5">
...
<input type="text" name="fieldn">
<input type="submit">
</form>

I am sorry.
I didn't clarify my request enough.
I know all too well how to use POST for forms.
My issue is, that I need to pass the form values to two other JSP pages after the initial POST has been made by the form.
Example:
1. my form post the field values to a select statement that checks table2
2. I then need to pass those same form field values back to the form, or to another insert statement, depending on the results from table2.

I think your issue is that (1) you don't want to pass the form values in the url because of size restrictions; and (2) if you pass them via POST, the form values are "request" level so you lose them after you process the page after the post.
I believe the request object stores all the values in a HashMap. Why don't you create your own HashMap, and give it "session" access? Then you can access the form values, update them whenever you want, and delete the HashMap when it is no longer needed.

Dorothy,
That sounds like a good option.
Would you have an example to share?

You could also create a form to store the hidden values after the first post... Then you could submit it to the other 2 pages using javascript.
