ibm mobilefirst - No MBean found for worklight project

Question

I have been getting this error while starting up my server with my worklight project (.war) deployed on it. Was wondering if anyone has any inputs. Below are the relevant information.

The system is set up in Redhat OS, Worklight version 6.2 consumer edition, DB2 as database and WS-Liberty 8.5.5.1 as server.

P.S: My application was available before this problem occured, however my worklight console was never working correctly (always had problem with message on worklight console saying "no runtime configuratin can be found"). It still says the same.

Answer 1

The first error is "FWLSE0188E: Failed to connect to DB2 database : Cannot create PoolableConnectionFactory ([jcc][10389][12245][3.67.27] Failure in loading native library db2jcct2, java.lang.UnsatisfiedLinkError: no db2jcct2 in java.library.path: ERRORCODE=-4472, SQLSTATE=null) [project MyProjectName]"

The recommended way to configure the DB2 data sources in Worklight is to use the JDBC 4.0 driver (db2jcc4.jar and its associated license jar files in the same directory), as described in the Worklight documentation (here and here). It does not involve the use of native code libraries.

Therefore I would check the data source definition in Liberty's server.xml file.
