ClassNotFoundException when using setVariable(...) with a custom POGO

[louisp]

I am calling setVariable(...) using a POGO, it does not raised any err, but later, when my BPMN reaches a Service Task I get the following err :

java.lang.ClassNotFoundException: <MyClass> at org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedWebappClassLoader.loadClass(TomcatEmbeddedWebappClassLoader.java:74) at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1119) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName0(Class.java:348) at org.activiti.engine.impl.util.ReflectUtil.loadClass(ReflectUtil.java:291) at org.activiti.engine.impl.util.ReflectUtil.loadClass(ReflectUtil.java:68) at org.activiti.engine.impl.variable.SerializableType$1.resolveClass(SerializableType.java:124)

Is there a way to make Activiti aware of this POGO ? I am already loading a custom JAR into my GroovyScriptingEngine, but it does not seem enough.

Please share your POJO.

Have you implemented the Serializable interface? it is mandatory to implement, for acitiviti to persist data in DB
