how to fix the issue where the agent does not report data and the version number is not displayed - Enterprise Distributed Application Service

After you install Enterprise Distributed Application Service (EDAS) Agent on an ECS instance, the EDAS Agent version number is not displayed.

Symptom

After EDAS Agent is installed, no prompt appears and the EDAS Agent version number is not displayed.

Cause

This issue occurs when a compatible Java Development Kit (JDK) is not installed or when an unsupported JDK version is in use on the ECS instance. EDAS Agent requires JDK 1.7.

Solution

Check the EDAS Agent log file for errors: If the log contains Java not found or other Java-related exceptions, the JDK is missing or incompatible.
```
cat /home/admin/edas-agent/logs/std.log
```
Verify the installed JDK version:
```
java -version
```
If the output shows JDK 1.5, run the rpm -e command to remove this version, and then reinstall EDAS Agent.
