We are using Tomcat 8.5 with Corretto 8 in the beanstalk. I have set all my configs properly, when i am deploying the code i am seeing below errors. ```auto Error opening zip file or JAR manifest missing : /home/ec2-user/elastic-apm-agent-1.36.0.jar agent library failed to init: instrument ``` Java\_OPS i am using ```auto -Xmx4256m -javaagent:/home/ec2-user/elastic-apm-agent-1.16.0.jar -Delastic.apm.service_name ``` ---

```auto Error opening zip file or JAR manifest missing : /home/ec2-user/elastic-apm-agent-1.36.0.jar agent library failed to init: instrument ``` This means that the JVM couldn't find the jar at this path: `/home/ec2-user/elastic-apm-agent-1.36.0.jar`. Please make sure you set your command line properly. I don't know why the below says: `-javaagent:/home/ec2-user/elastic-apm-agent-1.16.0.jar`, the error would have been for `1.16.0`. I am also not sure if what you provided is trimmed in the middle, or you really didn't set a value to the `-Delastic.apm.service_name` system property. This should be an easy fix, it is only a matter of getting the command line right. ---

i haven't trimmed. This are my JVM\_OPTIONS i have configured. ```auto -javaagent:"/var/lib/tomcat/webapps/elastic-apm-agent-1.36.0.jar" -Delastic.apm.service_name=nonprodqa-api -Delastic.apm.server_urls=http://url:8200 -Delastic.apm.environment=nonprodqa ``` Tomcat is failing to start. with the below error. Am i missing any quotes here? ```auto Feb 13 05:38:33 ip-10-0-1-5.us-west-2.compute.internal server[6037]: arguments used: start Feb 13 05:38:33 ip-10-0-1-5.us-west-2.compute.internal server[6037]: Error opening zip file or JAR manifest missing : /var/lib/tomcat/webapps/elastic-apm-agent-1.36.0.jar -Delastic.apm.service_name Feb 13 05:38:33 ip-10-0-1-5.us-west-2.compute.internal server[6037]: Error occurred during initialization of VM Feb 13 05:38:33 ip-10-0-1-5.us-west-2.compute.internal server[6037]: agent library failed to init: instrument ``` ---

I am able to fix the issue with below configuration. ```auto -javaagent:/var/lib/tomcat/webapps/elastic-apm-agent-1.36.0.jar -Delastic.apm.service_name=nonprodqa -Delastic.apm.application_packages=org.example -Delastic.apm.server_urls=http://10.0.1.180:8200 ``` ---

I am not familiar with `JVM_OPTIONS`, so I cannot say whether this is the right one. I normally use `CATALINA_OPTS`, which is appended only when using the startup script with `start`. In your last comment there is a bigger problem, where you added the agent to the `webapps` folder. The agent jar should never be loaded by the application other than through the `-javaagent` command! Make sure you move it from the `webapps` folder and any other folder from which jars are loaded by the app. It should also not be a dependency anywhere in your project. Please revert all changes you did, move the agent to a separate directory (like `/home/ec2-user/elastic-apm-agent-1.36.0.jar`) and follow our [documentation](https://www.elastic.co/guide/en/apm/agent/java/current/setup-javaagent.html#setup-tomcat). This should work. Your errors clearly indicate that the command line that gets built by the startup script is erroneous, so you will have to make sure you get it right. ---
