Dear Roman,

thank you for the fast response. In the previous conf. file I have
filled all possible parameters for datasource to eliminate
so "wrong" default parameter. But I obtain the same error message
for this minimal configuration:

<property name="UserName" value="SYSDBA"/>
<property name="LoginTimeout" value="5000"/>
<property name="UserName" value="SYSDBA"/>
<property name="MaxSize" value="5"/>
<property name="MinSize" value="1"/>
<property name="LoginTimeout" value="5000"/>
<property name="Database"
value="localhost/3050:c:/data/ejb_experiment.gdb"/>
<property name="Password" value="masterkey"/>
<property name="Pooling" value="true"/>
<property name="IdleTimeoutMinutes" value="35"/>
<property name="Database"
value="localhost/3050:c:/data/ejb_experiment.gdb"/>
<property name="Password" value="masterkey"/>
<property name="Pooling" value="true"/>

this is very strange for me, when write the DataSource connection in
standalone Java App, it is working fine.

Thank you, Jan
