I am getting below error when trying to start the tomcat using **systemd service**

```
systemd[1]: tomcat.service: Failed to execute command: Permission denied
systemd[1]: tomcat.service: Failed at step EXEC spawning /opt/tomcat/bin/startup.sh: Permission denied

```

**Below is my tomcat.service configuration**
