I am trying to create EntityManager at runtime so I can set different user name and password from a config.xml
Here is the code to to create the EntityManager
map.put(PersistenceUnitProperties.JDBC_USER, SystemConfig.getConfig().getString("jdbcUser"));
map.put(PersistenceUnitProperties.JDBC_PASSWORD, SystemConfig.getConfig().getString("jdbcPassword"));
map.put(PersistenceUnitProperties.JDBC_URL, SystemConfig.getConfig().getString("jdbcUrl"));
map.put(PersistenceUnitProperties.JDBC_DRIVER, "net.sourceforge.jtds.jdbc.Driver");
EntityManager eMgr = Persistence.createEntityManagerFactory("myPU", map).createEntityManager();
My program structure in unix: ~/test/myProgram.jar ~/test/lib/*.jar (all library and jdbc.jar here)
The program works fine when I run the program inside the folder /test/ However when I run the program under the root ~/ I get the Exception [EclipseLink-4021]. Any idea why??
Note: Ultimately I need to schedule the program using cron job.
