Jasper Reports “package net.sf.jasperreports.engine does not exist” exception in JDeveloper 11.1 using WebLogic only in EAR Web Page

Question

I\'m using JDeveloper 11.1, Oracle 11 and TIBCO JasperReports 6.0.1.

I\'m having problems trying to generate Jasper Reports from my web page (ViewController) while u

Answer 1

I used eclipse ecj-4.3.1.jar and it works.

Answer 2

First checks the dependencies of jasperReports - for example version 6.1.0 - https://mvnrepository.com/artifact/net.sf.jasperreports/jasperreports/6.1.0

With this you can see if there is any dependency that is missing in your lib directory (webApp) or inside your .jar (if it is a main application of java).

That mistake also happened to me, and I solved it by adding dependence

<groupId>org.eclipse.jdt.core.compiler</groupId>
<artifactId>ecj</artifactId>
<version>4.3.1</version>

I hope it supports you

Answer 3

Well, as somebody says it was necessary to use jdt-compiler-3.1.1.jar. I added it to /lib folder and now it is working.

It's really strange that this .jar is not in the installation product for TIBCO Jasper Reports 6.0.0 actually I descend until JR 3.7.6 which is the lowest version. The file is from 28/12/2008...

Nice...
