OSGi: using Third party .jar results in NoClassDefFoundError's

New Member Posts: 21 Join Date: 11/14/19 Recent Posts

Hi! I developed an OSGi module (Liferay 7.0 EE, service archetype) which uses jasperreports jar (v6.12.2) to generate PDFs. After Deployment I get a lot of errors (e.g. java.lang.NoClassDefFoundError: org/apache/commons/collections4/map/ReferenceMap). What do I have to do so that:

a.) my osgi module jar contains the neccessary jar and its dependencies.
b.) no more errors appear in the logs.To get access to the jar, I added it as a dependency in the the POM.

pom.xml

<dependency>
&nbsp; <groupid>net.sf.jasperreports</groupid>
&nbsp; <artifactid>jasperreports</artifactid>
&nbsp; <version>6.12.2</version>
&nbsp; <scope>compile</scope>
</dependency>

bnd.bnd

Bundle-Name: jasper
Bundle-SymbolicName: com.example.service.jasper
Bundle-Version: 1.0.0
Bundle-Activator: com.example.service.activator.JasperReportServiceActivator
Export-Package: com.example.service.jasper.api

Are there any clear instructions what to do in this specific scenario? I only found vague ones.

Since you are using compile scope, jasper is used to compile your module but is not including it or any transitive dependencies into the module. This is what is causing all of your no class def errors, unresolved references, etc.

When building your module, you need to either include the deps in the module (shadow them in or build an uber jar) or they have to be deployed and available in the OSGi container (potential issues here in dealing with conflicts).

Either way, without the dependencies your module will not start.

Hi David. Thanks for your reply. I removed the compile-scope in the pom above and also modified the bnd file you see below. Now with this configuration the errors are gone. Do you know if there is a more user-friendly way doing this?

Nope, that's pretty much it...

Unfortunately I get further errors. What is this?

Shut down Liferay, purge the osgi/state directory, then try again...

Thank you David. Deleting the files in osgi/state, liferay/work, tomcat/work, tomcat/temp and a restart solved the problem.
