I managed to figure out the problem. My package contained a POJO jar model which seems to poison the entire package and as a result none of my process defintions are available in the jbpm console.

The jar contained multiple features such as generics and one of the classes (called 'Field') was abstract. I reduced the jar to only contain the Field class and removed the "abstract" modifier. Still no result. The class looks like this:

package com.companyname.secretproject.common

import java.io.Serializable;

import org.json.simple.JSONAware;
import org.json.simple.JSONObject;

public class Field implements JSONAware, Serializable
{
          private static final long serialVersionUID = 8501917889951368463L;


          public static class Params
          {
                    public static final String DISPLAYABLE_NAME = "displayableName";


                    public static final String NAME = "name";


                    public static final String READONLY = "readonly";


                    public static final String REQUIRED = "required";


                    public static final String TYPE = "type";
          }


          protected String name;


          protected String displayableName;


          protected boolean readonly;


          protected boolean required;


          public String getName()
          {
                    return name;
          }


          public void setName(String name)
          {
                    this.name = name;
          }


          public String getDisplayableName()
          {
                    return displayableName;
          }


          public void setDisplayableName(String displayableName)
          {
                    this.displayableName = displayableName;
          }


          public boolean getReadonly()
          {
                    return readonly;
          }


          public void setReadonly(boolean readonly)
          {
                    this.readonly = readonly;
          }


          public boolean getRequired()
          {
                    return required;
          }


          public void setRequired(boolean required)
          {
                    this.required = required;
          }


          @SuppressWarnings("unchecked")
          public JSONObject toJSONObject()
          {
                    JSONObject o = new JSONObject();


                    o.put(Params.DISPLAYABLE_NAME, displayableName);
                    o.put(Params.NAME, name);
                    o.put(Params.READONLY, readonly);
                    o.put(Params.REQUIRED, required);
                    o.put(Params.TYPE, this.getClass().getSimpleName());


                    return o;
          }


          @Override
          public String toJSONString()
          {
                    return this.toJSONObject().toJSONString();
          }
}

My only idea is that the class name "Field" is somewhat reserved or the "problem" is that it implements an interface other than Serializable.

I would appreciate if someone could collect all the requirements for writing a domain specific POJO model.

Best regards,
Márton
