Problems with signature in jasperREports

Classic Servoy
1

I have 2 servoys, for to different apps, in one app the reports run okey, but in another when i try to show a report show me this messag error:

Exception Object: java.lang.Exception: class "net.sf.jasperreports.engine.base.JRBaseParagraph"'s signer information does not match signer information of other classes in the same package
MSG: class "net.sf.jasperreports.engine.base.JRBaseParagraph"'s signer information does not match signer information of other classes in the same package
class "net.sf.jasperreports.engine.base.JRBaseParagraph"'s signer information does not match signer information of other classes in the same package
Wrapped java.lang.Exception: class "net.sf.jasperreports.engine.base.JRBaseParagraph"'s signer information does not match signer information of other classes in the same package (/Applications/Servoys/Servoy6_QCinst/workspace/jMSI_mod_reports/globals.js#193)
	at /Applications/Servoys/Servoy6_QCinst/workspace/jMSI_mod_reports/globals.js:193 (openReport)

i signed all the .jar, copied the all plugins folder from the other servoy but the problem persist, anything what to do? is form the plugin or from the report?

I’m not a signing expert, but if I would get such an error, I would signing each Servoy App Server installation with the signtester tool from ServoyForge.
For me this is best praktice and is working without problems.

I signed ALL the jar inside of the application server, but the error persist.

You signed all jars yourself?
Did you remove the old/original signatures?

Yes, I used signister but I have the same error one after one

EDIT: Problem solved. I have merged jar in the same directory of and old version of iReport and the last one, i removed the old files and all it’s ok
