Error initializing tooling instance in Mule Anypoint Studio

I am new to Mule and was following the official tutorial in using the Anypoint Studio. I was trying to test the connection of a database connector when I found that there was an issue with the tooling instance, in which the following message was given.

Error-Test_DB_Connection

I went to check the status of the tooling instance, and it was not started. Then I tried to restart the tooling instance, but it failed as shown below.

Error-Restart_instance_failed

Below is the corresponding error message (in Workspace/.metadata/.log). Kindly see if there are any insights, thanks.

[Environment information]
Platform: macOS 10.13.4
AnyPoint Studio version: 7.1.2
Mule runtime version: 4.1.1 EE
JDK version: 1.8.0_172
Port 3306 outbound connection is open

Solution

  • I resorted to using the previous version (Anypoint Studio 6.4 with Mule 3.9) and there is no issue making a DB connection. In fact there isn't even a section in "Preference" which is about "Tooling" under "Anypoint Studio". Maybe there is some issue with Anypoint Studio 7.1.

    Nevertheless, falling back with the previous version should be one of the solutions.
