Thx for ur answers, I have reied what you say about the second
question, but it's do not work. This is how I have changed my
"context.xml" file:
===
<?xml version='1.0' encoding='utf-8'?>
<Context privileged="true" swallowOutput="true"
workDir="work\Catalina\photoalbum\" path="/" cacheTTL="0"
cachingAllowed="false" displayName="bannerEmbedded beta" docBase="."
cacheMaxSize="0" reloadable="true">
<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
resourceName="PhotoAlbum"/>
<Valve className="org.apache.catalina.valves.AccessLogValve"
directory="logs/photoalbum/" fileDateFormat="yyyy-MM-dd" suffix=".txt"
prefix="photoalbum_access_log."/>
<!--<ResourceLink name="PhotoAlbum" global="PhotoAlbum"
type="org.apache.catalina.UserDatabase"/>-->
<Resource type="org.apache.catalina.UserDatabase" description="User
database that can be updated and saved" auth="Container"
name="PhotoAlbum"/>
<ResourceParams name="PhotoAlbum">
<parameter>
<name>factory</name>
<value>org.apache.catalina.users.MemoryUserDatabaseFactory</value>
</parameter>
<parameter>
<name>pathname</name>
<value>conf/Catalina/photoalbum.localhost/photoalbum-users.xml</value>
</parameter>
</ResourceParams>
</Context>
===
I have removed the ResourceParams from the server.xml file and move it
into the context.xml but in the log I can read this errors messages:
1) javax.naming.NameNotFoundException: Name PhotoAlbum is not bound in
this Context
2) GRAVE: Catalina.start:
LifecycleException: No UserDatabase component found under key PhotoAlbum
3) 2005-02-07 09:55:30 UserDatabaseRealm[photoalbum.localhost]:
Exception looking up UserDatabase under key PhotoAlbum
javax.naming.NameNotFoundException: Name PhotoAlbum is not bound in this Context
do u know why? I have I have give you all the elements you need to help me.
