GroovyEvaluator not found

Question

I'll try to do my PIE 3D report in iReport, in my struts.xml i got this to call my report.

<action name="cargaReporte" 
        class="com.techera.eventos.action.MisVisitasAction" 
        method="cargaReporte">              
    <result name="success" type="jasper">
        <param name="location">/WEB-INF/jsp/reportes/reporteMisVisitas.jasper</param>
        <param name="dataSource">visitas</param>
        <param name="format">PDF</param>
    </result>
</action>

in my jsp i got this

<a href="cargaReporte">Reporte</a>

and when i clicked the link, the error is this

java.lang.ClassNotFoundException: net.sf.jasperreports.compilers.GroovyEvaluator
    at java.lang.ClassLoader.findClass(ClassLoader.java:522)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:423)

    at java.lang.ClassLoader.defineClass1(Native Method)
    at java.lang.ClassLoader.defineClass(ClassLoader.java:791)
        ...

Someone to tellme what I can do wrong?

I use the libraries:

groovy-all-1.7.5.jar

• iText-2.1.7.jar
• jasperreports-4.5.0.jar
• jcommon-1.0.15.jar
• jfreechart-1.0.12.jar
• struts2-jasperreports-plugin-2.3.1.1.jar
• struts2-jquery-chart-plugin-3.3.1.jar

Solution 1

Let me explain: if you're compiling your jasper report files (jrxml) with iReport-5.6.0 then you have to use jasperreports-5.6.0.jar at runtime..

Solution 2

I was able to resolve this by :

1. removing language="groovy"
2. (or) replacing language="groovy" with language="java" in my JRXML file

Don't forget to save and compile.

Solution 3

It usually happens when your ireport and jasper jar version is different. In such case compile the jrxml with java or your version of jar should be similar to ireport

String dir = request.getRealPath("/");
        
        try {
            JasperCompileManager.compileReportToFile(dir+ "/WEB-INF/jasper/SummaryReportExport.jrxml", dir+ "/WEB-INF/jasper/SummaryReportExport.jasper");
       } catch (Exception e) {
            e.printStackTrace();
            return ERROR;
        }
