How to use my own class in reports (iReports 3.5.2

[yelnaza]

Hi to all

I have a problem in my report.

I need to use custom class in it, but I don't know how to.

I tried to put path to jar file with my class file into CLASSPATH, tried to set my jar file in iReports- Tools - Options - CLASSPATH

but my report doesn't work. It compiles prefectly but doesn't fill data. I have this error:  java.lang.IllegalAccessError and message that my class can't be accessed from reports class.

Can anyone help me, please

this is a good question...

but there is something unclear when you describe your issue:

"It compiles prefectly but doesn't fill data. I have this error:  java.lang.IllegalAccessError and message that my class can't be accessed from reports class."

how it can compile perfectly also giving you an error?
can you be more clear (maybe reporting the exact error...) ?

Ok, when I said "compile prefeclty" I mean that when I go from Designer to Preview everything is ok.

When I try to run report with my parameter value  it  is crushing and log file said that filling report is impossible becouse report class can't access  to my class.

Very strange situation. Just create simple report on another computer, want check class - all working very well. Is order of jar files in classpath of iReports (Tools - Options - Classpath) important?

Can't figure out in what problem. Equal settings on different computers and one is working and another crushing.... Can this problem depend from system user?

have you tried the same report on two computer? not similar report, but exactly the same...

you can also try to import your class... (it's a bean class, an help class or what else?)

clicking on the main node of your report and then in the properties window on the "import" button setting the package of your class.

I use custom class but I'm not having problem.

I try to make new report with text field in it. In expression of text field I create new object of my class. On one computer it works, on another don't work's and log says:

from russia... wow :)

try to import your class as I have explained in the previous post, then, in the texfield use the expression:

(new InWords("1234")).toString() 

and not

new InWords("1234").toString() 

check if the cell type of the textfield is String

 

it seems to be a JVM problem...
have the two machines where you run the report the same JVM?

 

make a test and then give us a feedback :)

Yes,  JVM on my computes is different....

Thanks for advices, I'll try... and write there after

[yelnaza]

At last....

It was misprint in my class. It causes problem with class visibility.

Anyway thanks for help, especially about import custom classes. :)
