unable to log into database using oracle.apex.APEXExport class

I need to perform batch export of several APEX applications into .sql script. I am trying to use Oracle's unsupported (though packaged with 11g server) Java utility in question.

I have two database instances. Both of them are 11gR2 XE. One is running on my local VMWare machine for testing puproses, another one is running on remote APEX hosting.

The problem is, I cannot connect to latter instance. That's how I run it:

java -Duser.language=en -Duser.region=us oracle.apex.APEXExport -db my.hosting.net:1521:xe -user scott -password tiger -applicationid 101

And that's the error stack:

Exception in thread "main" java.sql.SQLException: ORA-01017: invalid username/password; logon denied

The funny thing is, I encounter no issues connecting to the very same schema using SQL*Plus.

And I also have absolutely no problems exporting applications from my local VMWare-based instance.

Any ideas of the direction I should look at?

Thanks.

Okay, if anyone else encounters the same issue... It helped when I issued alter user scott identified by tiger; where tiger was current password. So, basically, I just refreshed password and for some reason it all started to work.
