I have heard that we can use some little java codes in text field expressions.
I am looking for a sample code how can i use little java code expressions in textfields.

For ireport when a recognised code is entered then ireport is styling the text.
i tried if, else ,do, while...
they all are recognised because they all have been styled.
Can you give a sample code or a web site that demonstrates how i can use them in textfield expressions?

I think you are talking about the Jakarta Commons EL project.

No not exactually.
I know what jsp EL is.

This is different.
In properties of a textfield ,i think we can write java based scripting language.

Its not alright pure java .It's convention is similar to java.A script language which is used instead of formulas in RDF (oracle forms).

I wanted to make an experiment to see if some key words are recognised.

When a recognised keyword is written ireport is coloring that one.If its not recognised its not colorising the word.

I tried to type "if" , "else" ,"do" ,"while" ,"for","continue","break"...

They all have been recognised and colored it to bold,black immediately.

But for example if i write "sinasi" its not coloring.That means they have speacial usage.

Its like java but i dont exactually know its usage.And if i type them as it is in java ireport is giving me ClassInstanceCreation Exceptions...

I just wanna know a sample how to use that scripting language.

thank you.

I see - by Jasper you mean JasperReports, not the Jasper compiler.

I'm not quite sure what you're trying to achiev. This functionality exists in Oracle RDF, and you want to make it work in iReports?
