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

Xiaodi_Shi — Mon, 08 Dec 2025 02:15:11 GMT

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

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.
