I'd probably try to set
|useSystemClassLoaderAsParent="false"

all is all-right.
But when I modify context config as:
-------------------------------------
<Context
path="/SagittaWebShop"
docBase="../../eclipse/workspace/SagittaWebShop/web"
reloadable="true"
<Loader
reloadable="true"
checkInterval="1"
/>
<Realm
className="org.apache.catalina.realm.DataSourceRealm"
debug="99"
dataSourceName="jdbc/KaratDB"
userTable="dba.user_jsf_webusr"
userNameCol="usr_login"
userCredCol="usr_pass"
userRoleTable="dba.user_jsf_webusr"
roleNameCol="usr_role"
localDataSource="true"
/>
<ResourceLink
name="jdbc/KaratDB"
global="jdbc/SagittaDB"
type="javax.sql.DataSource"
/>
</Context>
---------------------------------------
- yes, only added <Loader .../> section, I got a error (catalina.log):

-----------------------------------------------
This happened in version of Tomcat 5.5.10 and newer... I'm running Tomcat 5.5.9 for a long time without any error(s), but yesterday I'm preparing upgrade of some servers and try tu update to 5.5.26...
In production server(s) isn't necessarily define <Loader... /> section,
but in developing environment...
So is some possible solution of this problem (some config) or it is a
BUG in Tomcat 5.5. from 5.5.10?
Any ideas?
King regards
