Error importing external jar in a custom component

Anonymous — Sat, 16 Nov 2024 09:43:52 GMT

Hello,

I'm trying to create a component for modbus communication. I run Talend ESB 5.5.1
When I try to instanciate a objet of the external jar EasyModbusJava.jar I face an error:

Exécution en erreur :Échec de la génération du code.
[----------
1. ERROR in C:\Workspace_talend_esb\.JETEmitters\src\org\talend\designer\codegen\translators\laita\TModbusBeginJava.java (at line 35)
de.re.easymodbus.modbusclient.ModbusClient modbusClient = new de.re.easymodbus.modbusclient.ModbusClient("192.168.0.10",502);
^^
de cannot be resolved to a type

Jar is referenced in tModbus_java.xml:

<CODEGENERATION>
<IMPORTS>
<IMPORT NAME="modbus" MODULE="EasyModbusJava.jar" REQUIRED="true"/>
</IMPORTS>
</CODEGENERATION>

The jar has been copied in:

TalendDirectory/plugins/org.talend.designer.components.localprovider_5.5.1.r118616/components/tModbus

and

TalendDirectory/lib/java directory

An extract of tModbus_begin.javajet:

<%@ jet 
imports="
org.talend.core.model.process.INode 
org.talend.core.model.process.ElementParameterParser
org.talend.designer.codegen.config.CodeGeneratorArgument
java.util.Map
java.util.List
"
%>
<%
CodeGeneratorArgument codeGenArgument = (CodeGeneratorArgument) argument;
INode node = (INode)codeGenArgument.getArgument();

String cid = node.getUniqueName();
de.re.easymodbus.modbusclient.ModbusClient modbusClient = new de.re.easymodbus.modbusclient.ModbusClient("192.168.0.10",502);

I've searched on you forum but didn't find anything that help me

I've tried to execute the same code in a tJava with tLibrary to load the external jar, and it worked fine, but in my custom component the library isn't recognized..

Hi
Have a try to import the class in the Import section:
<%@ jet
imports="
org.talend.core.model.process.INode
org.talend.core.model.process.ElementParameterParser
org.talend.designer.codegen.config.CodeGeneratorArgument
java.util.Map
java.util.List
de.re.easymodbus.modbusclient.ModbusClient
"
%>
If it still does not work, would you mind sending your custom component as well as external jar to me for testing?

Regards
Shong
