I'm trying to run my Batch application during this I want to connect to another application via some property file.

Seems that you have no jakarta/xml/ws/WebServiceException class definition in Java Runtime.

Still, you managed to compile this, which means either this class is not needed during the compilation process (for instance loaded through Class.forName) or it is marked as compile time only. I do not know what build tool you are using, but it seems you need to put declare dependency like this for Maven:

<dependency>
	<groupId>jakarta.xml.ws</groupId>
	<artifactId>jakarta.xml.ws-api</artifactId>
	<version>3.0.1</version>
</dependency>

Or like this for Gradle

compile group: 'jakarta.xml.ws', name: 'jakarta.xml.ws-api', version: '3.0.1'

P.S: I have noticed the jakarta package, I'm guessing you are in the process of transitioning from javax to jakarta, if so, you may find this SO post useful.
