Hi,

I am trying to perform exact Json creation steps mentioned in below link which takes delimited rows as input and writes into json using tWriteJSONField. While executing I am getting below error.

It is a compilation error, it seems you are using an unsupported JDK. What is your studio version and JDK version?

nu.xom.JDK15XML1_0Parser, i think you could try to reinstall talend 8 and just use JDK11, then install the jar for json component, cause it seem to be clearly a java version issue, and as far as i know for talend 8 jdk 11 is recomended.

you could also try to add this to your jvm parameters :

-XaddExports:java.xml/com.sun.org.apache.xerces.internal.parsers=ALL-UNNAMED,java.xml/com.sun.org.apache.xerces.internal.util=ALL-UNNAMED

Hello,

It looks like your machine has more than 1 version of Java installed on it.

Please refer to this online documentation about:

https://help.talend.com/r/en-US/8.0/installation-guide-open-studio-for-data-integration-windows/specify-another-jvm-to-launch-studio

Here is a related topic and feel free to let us know if this solution helps.

Hello,

From Talend Studio side

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

From Talend Remote Engine side

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.

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

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

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