XML to repot

2004-02-25 23:26

A silly nd dumb question perhaps, but I need to know.

 

What happens to the XML file that I create for reports? If I change value for one field in textElement as well as field (say amount), it is still giving me ClassCastException. Where should I look nnow?

 

I am sorry for ambiguous question, but modifying legacy code without any documentation; things don't get more complex than this!!!

 

TIA,

- Manish

Hi,

 

Make sure that the expression that you write inside

the <textFieldExpression> tag returns values that

are compatible with the "class" attribute of the same tag. The default is java.lang.String.

 

I hope this helps.

I have ensured this. It is java.lang.Integer

 

How do I find out what is the class returned by

$F{fieldname}

 

TIA,

Hi,

 

In the XML there is a <field> tag that introduces your

fieldname alog with its class.

 

Thank you,

Teodor

Yes in that also I have marked it as Integer (I think I did mentioned it in first post), but no luck!!!! :(

Hi,

 

No, I'm afraid you did not mention it in the first post.

You only told us about the ClassCastException.

And in the second post you asked about the type

of the $F{fieldname}, so you got your answer.

We're in a vicious circle here...

 

I suspect your report receives a custom data source

and does not have an SQL query of its own.

The cast exception might come from a mismatch

between the declaration of your report field and the

actual data found in the data source.

 

I hope this helps.

Maybe i did not make it clear, but this is what I meant by -

 

If I change value for one field in textElement as well as field (say amount)

 

I meant (1) I changed class in the textExpression as well as the <field> tag. My values indeed come from a custom data source (custom JDO of sorts..) and hence there is som much confusion. The exception indeed is due to mismatch.

 

Thank you very much for all your help. maybe I should have made it clearer in the first post.
