Qlik Talend Product: Facing issue while using tWriteJSONField Component to POST data

It is getting Java Error Response from JSON results back when using tWriteJSONField to POST data from postman in Talend 8, JDK 11.

superclass access check failed: class nu.xom.JDK15XML1_0Parser (in unnamed module @xxxxx) cannot access class com.sun.org.apache.xerces.internal.parsers.SAXParser (in module java.xml) because module java.xml does not export com.sun.org.apache.xerces.internal.parsers to unnamed module @xxxxx

Resolution

Talend Studio

Go to Studio ->Project setting -> Build-> Java version-> Module access Settings-> Custom

GLOBAL=java.xml/com.sun.org.apache.xerces.internal.parsers, java.xml/com.sun.org.apache.xerces.internal.util

GlobalModelAccessSettings

Talend Remote Engine

When Job was built by jdk 8/11, which also need neccessary configurations to let Talend Remote Engine support jdk 8/11.
In the <RE_installation>/etc/system.properties file, set the org.talend.execution.JAVA_*_PATH properties with the paths to your Java installations.

The following configuration is a feature introduced since R2025-03 for old task execution compatibility.

org.talend.execution.JAVA_8_PATH=/path/to/java8/bin
org.talend.execution.JAVA_11_PATH=/path/to/java11/bin
org.talend.execution.JAVA_17_PATH=/path/to/java17/bin

In the meanwhile, please consider jobs migration to jdk 17 , since jdk 17 would be the only support jdk version in next few years.

Cause

It is a compilation error and task execution compatibility issue.
