Márton Steierlein [https://community.jboss.org/people/stmarci] created the discussion "Re: Only the default "Evaluation" process is shown in the process list after restarting jBPM 5.2" To view the discussion, visit: https://community.jboss.org/message/726831#726831 -------------------------------------------------------------- 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.
