Strange error, need help

[ideni]

Hi,

i've got a java swing project wich uses JasperReports to generate contract reports. Everything works fine. So far so good.

 

Now i need to adjust the report that way, that i need to put in a horizontal line and place all elements underneeth the line 5 pixels lower. That's pretty easy ..... i thought.

So after i made theses adjustments, i faced a problem that i can't compile the report anymore. So i deleted the report file, and replaced it with that one from the backup. Than tried to compile and it worked. After i've tried some time, i adjusted the report file from the backup by placing a space. After that i deleted the space again and saved the file. So the file is the same as that one from the backup. But as i thought, i can't compile the report anyway.

I always get following error:
