anonymous wrote : always from the console, if we modifying the DataSource is actually modified the file under the directory data / attachments / This statement is confusing. What console? In Jboss AS, embedded jopr is the admin console, and you just now stated that embedded jopr places datasource config files (*-ds.xml) in the server/xxx/deploy directory. And yes you can modify the *-ds.xml files using any text editor. That is the usual mechanism for editing those files (embedded jopr is new and previously all configuration was done by editing the config files directly using any text editor).
