How to set password for dbxml in java program

Question

When I calling XmlManager.openContainer() by a XmlContainerConfig object set to XmlContainerConfig.setEncrypted("mypass")
it always says:
BDB XML: Database environment not configured for encryption
but I can not find the way to construct the Environment for the database,
When I use:
envcfg = EnvironmentConfig.DEFAULT;
envcfg.setEncrypted("mypass");
env = new Environment(new java.io.File("/some/path/"), envcfg);
it says:
java.io.FileNotFoundException: No such file or directory

Hi,
Please follow Vyacheslav's advice. In addition, make sure that the path to the environment really exists. The Environment() construct will not create the directory structure if it does not exist.
Also, note that containers cannot be converted to an encrypted format after they have been created. You'll need to dump and re-create them.
Another remark; you've configured encryption for the environment:
envcfg.setEncrypted("mypass");Since the container is opened within an XmlManager's underlying environment which is configured for encryption you shouldn't set an encryption password at the container's level:
XmlContainerConfig.setEncrypted("mypass");http://www.oracle.com/technology/documentation/berkeley-db/xml/java/com/sleepycat/db/DatabaseConfig.html#setEncrypted(java.lang.String)
The environment wide encryption password will be used to encrypt data in the databases, containers, opened within that environment. Otherwise, if you want to encrypt stores (databases/containers) individually or encrypt just some of them, you'll need to not specify an encryption password at the environment's level and set it only at store's level.
