Question

I have a JBoss application on google cloud VM which has an API to upload a zip files. I am getting below error while making call to API. Note this happens only with JBoss on google Cloud but not with non-cloud application :

CLASSPATH on the Google Cloud is not set up properly. You will need to update it to make sure it includes the referenced class org.apache.james.mime4j.message.Message .
