Recently we upgrade itext jar from 2.1.7
to itextpdf-5.4.2.jar
but getting below nested exception is
java.lang.NoClassDefFoundError: com/lowagie/text/pdf/FontMapper exception
and we are using jasper reports 4.7.0
in that they are using below package
com/lowagie/text/pdf/FontMapper
only that's why it causes a problem. How to resolve this issue. (it's mandatory we have to upgrade itext jar at any cost)
