thanks for your help.
the solution is a bit another, as i managed to find out:
there was a misconfigured resource in web.xml:
<resource-ref>
<description>Test ss</description>
<res-ref-name>jdbc/show</res-ref-name>
<res-type>org.apache.commons.dbcp.datasources.PerUserPoolDataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
that raised an exception:
[#|2007-08-21T12:37:13.115+0400|SEVERE|sun-appserver9.1|javax.enterprise.system.container.web|_Threa

and all following resouces (even correctly configured) failed to initialize. i think, it could be a bug in glassfish
