Nodejs: Spawn jar (non executable)
248
April 26, 2018, at 08:46 AM
I have a Java jar file, which is not executable(does not have a main method). However I would like to invoke a particular class and its methods from my node.js application. I am currently using the below:
var child = require('child_process').spawn(
'java', ['-cp', "abc.jar", com.abc.ABCClass]
);
How now can I invoke the method in the ABCClass with appropriate arguments? I currently get an exception such as below:
A JNI error has occurred, please check your installation and try again
Exception in thread "main"
Error: java.lang.NoClassDefFoundError:
org/apache/kafka/clients/consumer/KafkaConsumer
Thanks in advance. I am looking for a solution to call the method in that class.
