Unknown error in Repast: does not find some module?

I am launching a model that was created with an old version of repast (RepastSimphony 1.2.0) and I am trying to run it an the latest version of Repast.
I have imported manually the scenarios files to the best of my abilities (I am a beginner with Repast).
Now, when I launch the model in Repast, it has en error because it cannot find a certain file/library/module (I am unsure).
Now, I am not sure whether this is a Repast internal library or some piece of code that I should have been given and that is missing...
Any insight about this error will be welcome !
The error is this one:
WARN [AWT-EventQueue-0] 13:20:38,158 ObjectActionLoader - Error loading information from data. Continuing with model loading.

Incidentally, I tried to run a model from the model library (zombies) and it launches and works properly.

Conversion Error in JMeter through Java. What dependencies are missing?

From https://www.blazemeter.com/blog/5-ways-launch-jmeter-test-without-using-jmeter-gui, I have this test file:
public class JMeterTests {
StandardJMeterEngine jmeter;
HashTree testPlanTree;
#BeforeEach
void init() throws Exception {
// JMeter Engine
jmeter = new StandardJMeterEngine();
// Initialize Properties, logging, locale, etc.
JMeterUtils.loadJMeterProperties("src/test/java/com/tests/JMeterTests.java");
JMeterUtils.setJMeterHome("/usr/local/Cellar/jmeter/5.4.1");
JMeterUtils.initLocale();
// Initialize JMeter SaveService
SaveService.loadProperties();
// Load existing .jmx Test Plan
FileInputStream in = new FileInputStream("src/test/jmeter/my.jmx");
testPlanTree = SaveService.loadTree(in); // <-- testPlanTree is null, did not load
in.close();
}
#Test
void fromExistingJmx() throws MalformedURLException {
// Run JMeter Test
jmeter.configure(testPlanTree); // <-- Fails since testPlanTree is null
jmeter.run();
}
}
As a result, I get this error:
ERROR 2021-10-19 13:29:31.301 [jmeter.s] (): Conversion error com.thoughtworks.xstream.converters.ConversionException: org.apache.jmeter.extractor.json.jsonpath.JSONPostProcessor : org.apache.jmeter.extractor.json.jsonpath.JSONPostProcessor

I've already confirmed my.jmx works in GUI mode.

From https://www.blazemeter.com/blog/5-ways-launch-jmeter-test-without-using-jmeter-gui, you have the following statement:
Have the required JMeter jars from /lib and especially /lib/ext folders of your JMeter installation in your project or module class path.
If it is not clear enough get Apache JMeter Components » 5.4.1 library in your project classpath
Also you made a mistake in copying and pasting this line:
JMeterUtils.loadJMeterProperties("src/test/java/com/tests/JMeterTests.java");
it should point to jmeter.properties file, preferably the original one.

How do I add and call a custom Java class inside a jBPM Process?

I have a local jBPM 7.33 with a simple process. At one point in the process, I need to generate a PDF file.
I want to do it by creating a very basic Java class that is run in a Task. The class would get variables from the process scope, generate the PDF and save the generated blob (or filesystem path) as a process variable.
How do I add a custom class and then call that class?

that's what we call it WorkItemHandler , your java class will be a customized jbpm task
First of all install jbpm in eclipse
Create a jBPM project in eclipse (tick Build the project using Maven)
create a java class that implements WorkItemHandler. it will be in this format.
package com.example;
import org.kie.api.runtime.process.WorkItem;
import java.util.HashMap;
import java.util.Map;
import org.drools.core.process.instance.WorkItemHandler;
import org.kie.api.runtime.process.WorkItemManager;
public class WorkItemTest implements WorkItemHandler {
#Override
public void executeWorkItem(WorkItem workItem, WorkItemManager manager) {
workItem.getParameters().toString();
/**Input Variables***/
String stringVar = (String) workItem.getParameter("stringVar");
/***
*
*
* YOUR CODE
*
*/
String msg = "done";
/**Output Variables in a HashMap***/
Map<String, Object> resultMap = new HashMap<String, Object>();
resultMap.put("Result", msg); //("name of variable", value)
manager.completeWorkItem(workItem.getId(), resultMap);
}
#Override
public void abortWorkItem(WorkItem workItem, WorkItemManager manager) {
System.out.println("Aborted ! ");
}
}
Build a jar file of this project (with maven).
From the workbench, go to Artifact, upload the jar
click on this icon, then artifacts
from the settings of your project, go to dependencies, and add from repository the uploaded artifact
from the settings of your project, go to Deployments / Work Item Handler and add a new work Item Handler : type its name and how to instantiate it (new com.example.WorkItemTest())
Finally, go to the Asset "WorkDefinitions" , define your work item (so you can see it in the workflow designer tool) as follow
[
"name" : "WorkItemTest",
"parameters" : [ //inputs
"stringVar " : new StringDataType(),
],
"results" : [ //outputs
"Result" : new ObjectDataType(),
],
"displayName" : "WorkItemTest",
"icon" : "defaultservicenodeicon.png"
]
you can now find this task in "service tasks" of your workflow designer tool (refresh before)

Compile Jython3 sources on Windows

CONTEXT :
I need to call a "file.py", where is implement my class "myClass", by the Python language OR the JAVA language through Jython.
I do in my "file.py" :
try :
# Jython source file
from com.local.mylocal.jython import ImyClass
except :
ImyClass = None
from threading import Thread
class myClassMetaClass(type) :
def __new__() :
if IClient is None :
bases = (Thread,)
else :
bases = (Thread, ImyClass,)
return type.__new__(metacls, nom, bases, dict)
class myClass(metaclass=myClassMetaClass) :
pass
When I run my PYTHON code, my class : myClass is instance with all metaclass she need. My code run.
When I run my JAVA code who call my PY class through Jython, my code error is :
Exception in thread "main" SyntaxError: ("mismatched input '='
expecting RPAREN", ('../file.py', 52, 22, 'class
myClass(metaclass=myClassMetaClass) :\n')) Blockquote
INVESTIGATION :
I see in "https://github.com/jython/jython3" isaiah solved my probleme.
PROBLEME :
I can't compile the source code on my Windows environement (need : POSIX ...).
I need the "jython3.jar" file.
REQUEST :
How compile jython3 souces on my Windows environement ?
Is it possible to acces to a "jython3.jar" file ?

com.thoughtworks.xstream.converters.ConversionException

[EDITED]
The project i'm working on is a 3 folder project in Java J2EE with servlets and Hibernate for the persistance. The structure is as follow: - Admin -> the main program with the beans and HTML/CSS - Jar -> with the jars, Hibernate tools and classes - War -> with the Servlets
Between them, I use Xstream to share the classes and important info.
I'm using Eclipse and Tomcat 7.
Hope that with this all of you get the global idea.
This what the Xstream debugger said:
Caused by: com.thoughtworks.xstream.converters.ConversionException: satdata.musicoterapia.hibernate.Terapeuta0 : satdata.musicoterapia.hibernate.Terapeuta0

Where the problem occurs: below, in the comment

If something is missing, ask and I'll put it here. Thanks for all!!!

In your servlet code you are are mentioning :
xstream.alias("Terapeuta", Terapeuta.class);
In XML file it is given as:
<terapeuta class="satdata.musicoterapia.hibernate.Terapeuta0" resolves-to="Terapeuta">
So in logs you are getting error as:
The exception in logs says:
com.thoughtworks.xstream.mapper.CannotResolveClassException:
satdata.musicoterapia.hibernate.Terapeuta0
it seems your class namein MXL should be satdata.musicoterapia.hibernate.Terapeuta
satdata.musicoterapia.hibernate.Terapeuta0
