Thanks ! :-D
I have found the solution.
It's necessary to add commons logging library.

Hello everybody,
I want to use Modbus4J rather than Jamod. I use Modbus4J version 3.0.0.
I'm trying to test the smallest possible example :
package testModbus;
import com.serotonin.modbus4j.ModbusFactory;
import com.serotonin.modbus4j.ModbusMaster;
import com.serotonin.modbus4j.code.DataType;
import com.serotonin.modbus4j.ip.IpParameters;
import com.serotonin.modbus4j.locator.BaseLocator;
public class Main {
public static void main(String[] args) throws Exception {
IpParameters params = new IpParameters();
params.setHost("localhost");
params.setPort(502);
ModbusFactory masterF = new ModbusFactory();
ModbusMaster master = masterF.createTcpMaster(params, false);
master.init();
System.out.println(master.testSlaveNode(5));
// Define the point locator.
BaseLocator<Number> loc = BaseLocator.holdingRegister(1, 0, DataType.TWO_BYTE_INT_UNSIGNED);
// Set the point value
master.setValue(loc, 1800);
// Get the point value
System.out.println(master.getValue(loc));
}
}
I have this error when I tryto execute the Java program :
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
at com.serotonin.modbus4j.ip.tcp.TcpMaster.<init>(TcpMaster.java:57)
at com.serotonin.modbus4j.ModbusFactory.createTcpMaster(ModbusFactory.java:69)
at testModbus.Main.main(Main.java:18)
Caused by: java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory

at java.lang.ClassLoader.loadClass(Unknown Source)
at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
... 3 more
With another bigger test, the error is the same.
I don't know where is the real problem with the code, or configuration, ... ?
Thanks you in advance for the help :-)
