在Websphere Liberty中启用jpa和jdbc的问题

Question

I am following these exercises for learning Liberty.

I am having an issue in he Lab 3 - Module 2.2 Liberty and JPA (DB2) . After setting all the JDBC and Data Source details, i restart the server and i do not see the two lines that mention the dataSource and jdbd driver.

[AUDIT] J2CA8004I : The dataSource DB2Connection is avilable as jdbc/DB2Connection. [AUDIT] J2CA8000I : The jdbcDriver my JDBCDriver is available.

How can i know if the jpa and jdb features ae correctly set?

This is the server.xml

<!-- Enable features -->
<featureManager onError="WARN">
    <feature>jsp-2.2</feature>
    <feature>jpa-2.0</feature>
    <feature>jdbc-4.0</feature>
</featureManager>

<!-- To access this server from a remote client add a host attribute to the following element, e.g. host="*" -->
<httpEndpoint id="defaultHttpEndpoint"
              httpPort="9080"
              httpsPort="9443" />


<jdbcDriver id="myJDBCDriver">
    <library name="DB2Lib">
        <fileset dir="C:\wlp\db2jdbc" includes="db2jcc4.jar, db2jcc_license_cu.jar"></fileset>
    </library>
</jdbcDriver>
<dataSource jndiName="jdbc/DB2Connection" id="DB2Connection"
    jdbcDriverRef="myJDBCDriver">
    <properties.db2.jcc databaseName="SAMPLE" serverName="igacloud" password="{xor}FhgeOz1tPj08" user="db2admin"></properties.db2.jcc>
</dataSource>

Unlike Classic WebSphere, which has a "test connection" capability in its admin console (datasource panel), there is no equivalent means with WebSphere Liberty yet. Have you tried testing the connection with a simple "Hello World" JPA application?

The CWWKF0012I message is simply confirming what features have been enabled - some features depend on other features and automatically enables them, which is why you see more features than defined in your server.xml.
