How to specify anywhere ubication of JPA configuration files to JPA ?
How I specify a directory any where are the configuration files of JPA, i.e persitence.xml and orm.xml.
For example, I have a directory named \jpafiles and here are the persistence.xml and other mapping files, then in a application how to do for indicate that the mapping files are located into ...\jpafiles ?.
As well as Hibernate, by using a instance of Configuration, for example:
String jpafile="....\persistence.xml "; //path relative or absolute
String mapdir="...\orm.xml"; //path relative or absolute
Configuration cfg= new Configuration();
File cfgFile = new File(jpafile);
File cfgDir = new File(mapdir);
if( cfgDir != null && cfgDir.length() > 0){
cfg.addDirectory(cfgDir);
}
if( cfgFile != null && cfgFile.length() > 0){
cfg.configure(cfgFile);
}else{
//File configFile = new File(jpaURL.getPath() + "/persistence.xml");
File configFile = new File(jpaURL.getPath() + "/persistence.xml");
cfg.configure(configFile);
}
...
Class driverClass = testLoader.loadClass(cfg.getProperty("connection.driver_class"));
Driver driver = (Driver) driverClass.newInstance( );
WrappedDriver wd = new WrappedDriver( driver,
cfg.getProperty("connection.driver_class"));
Are there any way using the Api in JPA? or Is there any way to do?
