MySQL Cluster 7.2.8 for windows does not contain ndbclient

[Jay Lim]

Hi,

I have previous developed a Java app with ClusterJPA as the persistence framework on a linux machine. After installing MySQL Cluster 7.2.8 in Windows , my app could not run due to the following exception:

SEVERE: Attempt to load native library ndbclient from path c:\mysql\lib failed with class java.lang.UnsatisfiedLinkError (no ndbclient in java.library.path).
Exception in thread "main" <openjpa-2.2.0-r422266:1244990 nonfatal general error> org.apache.openjpa.persistence.PersistenceException: Error getting connection to cluster with properties {com.mysql.clusterj.connect.verbose=0, com.mysql.clusterj.connect.retries=4, com.mysql.clusterj.connect.delay=5, com.mysql.clusterj.connectstring=localhost:1186, com.mysql.clusterj.max.transactions=1024, com.mysql.clusterj.connect.timeout.before=30, com.mysql.clusterj.database=housedb, com.mysql.clusterj.connect.timeout.after=20}:

It seems to me that the ndbclient is missing from the lib folder. In fact in the windows' version of the lib folder, only "ndbclient_static.lib" is present. On the other hand, in linux, various files (libndbclient.so, libndbclient.so.6.0.0, libndbclient_static.a & ndb_engine.so) are present. Please correct me if I am wrong, but is the windows version really missing that file to run the ndbclient? If so, is there any remedy for this?

Thank you!
