Servoy JasperReports Plugin

As suggested by Andrei Costache I tried to use the new version of Jasper Plugin which includes support for styles.
I modified my '.jrxml' file and added the line
<template><![CDATA[com.servoy.plugins.jasperreports.JasperReportsResourceLoader.loadStyle("databridge.jrtx")]]></template>
This are the paths defined on Servoy Server Admin Page:
directories.jasper.extra: /home/report/SY/styles/,/home/report/SY/images/
directory.jasper.report: /home/report/
('databridge.jrtx' is on the the folder /home/report/SY/styles/ and '.jrxml' file is in a subdirectory under '/home/report/').
When i tried to compile report on my developer it returns an error. This is the command line:
plugins.jasperPluginRMI.compileReport('avviso_arrivo_merce_a.jrxml');
the error returned is attached as 'a1.jpg'.
Otherwise, if I add a style reference and select my 'databridge.jrtx' it seems to work (it leaves me to compile report). I move file on server under the right directory but if I try to print via client it returns another error.
As told by Andrei I also tried to call directly the not-compiled file ('.jrxml') but it returns the same error which is returned if i try to compile it in my developer.
I hope that u can help me as soon as possible so I can implement styles in my reports (I use a lot of them and this will be a very useful feature!)

Write me if u need some other explanations (sceresini@databridge.it).

Best regards
