Hello,

In a JUnit-Test and in a Ajax-Server I try to validate an Object with
com.opensymphony.xwork2.validator.DefaultActionValidatorManager (Version
2.3.15.3).

The MyObject-validation.xml file is provided in the same directory as the
MyObject-Class (no action alias used).

I instantiate the validator manually with the new operator because the
ActionValidatorManagerFactory is no longer supported in the version
2.3.15.3:

--------------------------------------
DefaultActionValidatorManager validator = new
DefaultActionValidatorManager();
validator.validate(myObject, null);
--------------------------------------

but at runtime I get a NullPointerException:

--------------------------------------
java.lang.NullPointerException

The problem seems to be caused by the fileManager, that is set to NULL.

Has anyone an idea how to solve the problem?
How is the DefaultActionValidatorManager used correctly?

You must inject FileManagerFactory - manually via setter (new
DefaultFileManagerFactory()) - but as far I understand you use
DefaultActionValidatorManager outside struts, right? If in struts
action, you can use @Inject to inject proper instance.


Regards

Do you simply mean:

-------------------------------------------------

validator.setFileManagerFactory(new DefaultFileManagerFactory());
validator.validate(request, null);
--------------------------------------------------
?



---------------------------------------------------
java.lang.NullPointerException

---------------------------------------------------



Thanks,
Thomas

DefaultActionValidatorManager validator = new DefaultActionValidatorManager(); The DefaultFileManagerFactory is not instantiated properly. I get the following exception now: at com.opensymphony.xwork2.util.fs.DefaultFileManagerFactory.lookupFileManager(DefaultFileManagerFactory.java:57) at com.opensymphony.xwork2.util.fs.DefaultFileManagerFactory.getFileManager(DefaultFileManagerFactory.java:41) at com.opensymphony.xwork2.validator.DefaultActionValidatorManager.setFileManagerFactory(DefaultActionValidatorManager.java:73) Isn't there an easy way to initialize the DefaultActionValidatorManager properly?
