我已經設置了JNDI資源，但遇到了一個問題我不確定如何在我的apache-tomcat-8.0.36服務器上進行更正。javax.naming.NameNotFoundException：在此上下文中未綁定名稱[jdbc/FsEDBUser]
我context.xml文件包含以下內容：
<ResourceLink name="jdbc/FsEDBAdmin" global="jdbc/FsEDBAdmin" type="javax.sql.DataSource" />
<ResourceLink name="jdbc/FsEDBUser" global="jdbc/FsEDBUser" type="javax.sql.DataSource" />
<Resource name="jdbc/FsEDBAdmin" auth="Container"
type="javax.sql.DataSource" driverClassName="org.postgresql.Driver"
url="jdbc:postgresql://location"
username="user_admin" password="pass"
maxActive="20" maxIdle="10" maxWait="-1"/>
<Resource name="jdbc/FsEDBUser" auth="Container"
type="javax.sql.DataSource" driverClassName="org.postgresql.Driver"
url="jdbc:postgresql://location"
username="user_user" password="pass"
maxActive="20" maxIdle="10" maxWait="-1"/>
我web.xml：
<resource-ref>
<description>Admin Connection</description>
<res-ref-name>jdbc/FsEDBAdmin</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
<resource-ref>
<description>User Connection</description>
<res-ref-name>jdbc/FsEDBUser</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
我還使用這些連接定義身份驗證Realm： server.xml：
<Realm className="org.apache.catalina.realm.LockOutRealm">
<!-- This Realm uses the UserDatabase configured in the global JNDI
resources under the key "UserDatabase". Any edits
that are performed against this UserDatabase are immediately
available for use by the Realm. -->
<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
resourceName="UserDatabase"/>
<Realm className="org.apache.catalina.realm.DataSourceRealm"
digest="digest_method" dataSourceName="jdbc/FsEDBAdmin" userTable="schema.table_name"
userNameCol="name_col" userCredCol="pass_col"
userRoleTable="schema.table_name" roleNameCol="rolename_col"
localDataSource="true"/>
</Realm>
但是當我啓動我的應用程序時，我收到標題中提到的錯誤。如果需要，我可以提供完整的堆棧跟蹤。
我想補充一點，這是工作在一個點，最近的變化是使用Realm進行身份驗證。很明顯，我在一個地方或另一個地方定義這些資源時犯了一個錯誤，所以另一組眼睛告訴我在哪裏將會非常感激。謝謝。
編輯：這是我如何我打電話的資源：
