hi,

i need to call java bean through iReport.

i.e menu->DataSource->Report Query->javaBean Datasource.

if i am trying this it gives error:

 

class npt not found!

check your classpath and retry.

 

i had already checked my class path.

can anyone help me out.

 

and one more thing i want to know is that could stored procedure could be called using iReport or not.

thanks you

hi

 

ad 1)

i've tried this out and got no error - maybe you should create a new folder, copy the class file to this folder and add the path of this folder to the class path - just to be sure

 

ad 2)

yes it is possible - if you want to call a function tell me if you managed to retrieve more than one row.

Nasiraliadil,

1) does the report have to display a collection of java beans, or do you need to instantiate the bean to call on some of its methods ?

Please provide your : a) path where iReport is installed b) content of your classpath c) Location of and the name of the bean that you need to call

hi

 

well concerning stored procedures you might run into troubles but i've tried out the following:

 

call a procedure/function which is returing a set of records based on a view parameters.

 

the problem in fact was that i got only the last returned record although all records where processed by the stored procedure.

 

i haven't managed to solve this problem until now! maybe someone could tell you more in this case ...

 

concerning the first issue:

 

i agree with polrtex - more infos would be great to solve your problem.

be sure you call the bean with the contained package

Hello All,

 

I'm having the exact same problem the gentleman with the original post was/is having.

 

I need some clarification on this classpath variable.

 

When I write code in an IDE, I import a bean with a particular path (such as "com.packa.packb.MyBean"), and it works.

 

Now is this the same path I put into the IReport Report Query window? I tried this and it doesn't work. It gives a 'Check your classpath!' error.

 

Please help!

 

Thanks
