Hello all, after a clean install, I am getting the error below. This is my configuration:
Liberty profile installed with WLS
Exception thrown by application class
The stack trace in the server.log points to here:
Invocation of init method failed; nested exception is java.lang.RuntimeException:
java.lang.ClassNotFoundException: Class org.hsqldb.jdbcDriver not found in Worklight platform or project /worklight
I am not using authentication, nor I have created any projects per say. I a currently going over again over the settings and configuration material.
Does anyone have a lead into what may be causing this exception to be thrown? Or maybe a lead on specific troubleshooting steps. I have done the prerequisite Google search and DeveloperWorks searches.

Re: "Exception thrown by application class" error after installing 188.8.131.52012-09-13T18:16:08Z in response to SystemAdminI'm not sure why you have this issue after a clean install, but a workaround was given here:
Re: "Exception thrown by application class" error after installing 184.108.40.206012-09-14T16:09:10Z in response to SystemAdminCan you please provide your worklight.properties file and the server.xml of your liberty profile. (The properties file is located in the war file that you have deployed to the Liberty profile)

Normally you get this error if the database access to the core WL database is not properly configured as Worklight tries to establish connectivity with the database at the startup.
Now what I suspect here is to what database your worklight is configured to connect to and if it is using some invalid driver configuration values or to any invalid database location or invalid database credentials, then you would see such errors.
For that reason I have asked you to send me the server.xml for your liberty as well as worklight.properties file or you can take a look at them to see if it is configured correctly.
Re: "Exception thrown by application class" error after installing 18.104.22.168012-09-18T17:24:21Z in response to SystemAdminThanks a ton! It was the hsqldb.jar file missing in my /opt/IBM/Worklight/server/wlp$ cd usr/shared/resources/lib folder. Once I added that I was able to hit the login screen at localhost:8080/worklight/console
