Jasper Java Compile NoClassFound Exception

问题

Despite the question asked before, I cannot solve the problem by using them. I am currently trying to generate pdf file via using the jasper report.However, I always get an exception related with the jar dependencies. Despite, I add following jars file into my build path,

jasperreports-6.0.4.jar
commons-logging-1.2.jar
commons-beanutils-1.9.2.jar
jasperreports-javaflow-6.0.4.jar
commons.digester3-3.2.jar
commons-collections4-4.0.jar

program generates me class not found exception either related with collections. My main goal is via using jrxml file generate a pdf. I am using iReport 5.6.0 to generate jrxml file. Any help is appreciated. The Stack trace of error is below;

I manage to solve problem and I want to share the answer in order to help the community. The jar dependencies can be gathered via the pom.xml. However, the easy way relies on the iReport (jrxml generated version) installed folder. There is a folder in the location Jaspersoft\iReport-x.x.x\ireport\modules\ext (depends on OS). You can get the following jar files from there;

jasperreportsXX.jar
commons-loggingXX.jar
commons-beanutilsXX.jar
commons.digesterXX.jar
commons-collectionsXX.jar
iTextXX.jar
jtd-compilerXX.jar
groovy-allXX.jar

Then all problems are gone. Hope this helps to other user who meets the problem.

Regards.
