textbook example 12-3(david pasons java/xml) - DAO / DB-POOL / TOMCAT

At localhost
http://localhost:8080/jspadv/webhomecover/listclaims.jsp
I do NOT know, how debug? In debug a javabean, how check it is giving to other component CORRECT data?
The below means not find data ...? in db? may where clause faults?

What is claimCollection.claims?

Is claims a list inside claimCollection?

Is it possible to have a look at how com.webhomecover.beans.ClaimCollection is made?

Last thing: you don't need to write line 26 if you use jstl.

claims is a list of claim.
String x=new String(); provides empty string or needed inside parenthesis "" (doublequotes)?

is it faults where clause?

The constructor String() is ok.
Well, did you set in your servlet/action a request or session attribute with name claimCollection and with value a ClaimCollection object ?

Try this:

in your servlet set your collection as attribute to your request, with the following line.



and in your jsp you change the items on your forEach loop in this way:



Remember to delete line 26 in the jsp you posted.

It seems it's not, Leonidas, or you wouldn't have posted a question...
Check the solution i proposed to you, if you want, and see what happens.
If it won't work the problem is elsewhere, but we made a step further
