    <p>I am new to setting up JNDI resources and setting up JNDI resources in Tomcat.</p> <p>I inherited a servlet application. It runs on a test server via WebLogic. The servlet application accesses its database resource in the following way:</p> <pre><code>ctx = new InitialContext(); ds = (javax.sql.DataSource)ctx.lookup("myDataBaseName"); conn = ds.getConnection(); </code></pre> <p>When I tried that in a test JSP it doesn't work. I get</p> <pre><code>javax.naming.NameNotFoundException: Name myDataBaseName is not bound in this Context </code></pre> <p>However I was able to make the test JSP work if I altered the test JSP code thus:</p> <pre><code>ctx = new InitialContext(); Context envContext = (Context)ctx.lookup("java:/comp/env"); ds = (DataSource)envContext.lookup("myDataBaseName"); conn = ds.getConnection(); </code></pre> <p>I have this entry in TOMCAT_HOME/conf/context.html ( I'm just using it as a dev environment on my box )</p> <pre><code>&lt;Resource name="myDataBaseName" auth="Container" type="javax.sql.DataSource" driverClassName="oracle.jdbc.OracleDriver" url="jdbc:oracle:thin:@blahblahblah:1521:database3" username="joeuser" password="password" maxActive="20" maxIdle="30" maxWait="-1"/&gt; &lt;/Context&gt; </code></pre> <p>And I have this in my TOMCAT_HOME/conf/web.xml:</p> <pre><code>&lt;resource-ref&gt; &lt;res-ref-name&gt;myDataBaseName&lt;/res-ref-name&gt; &lt;res-type&gt;javax.sql.DataSource&lt;/res-type&gt; &lt;res-auth&gt;Container&lt;/res-auth&gt; &lt;/resource-ref&gt; </code></pre> <p>I read about 10 stackoverflow pages on related problems, but I am not familiar enough with setting up JNDI resources to abstract those solutions to my problem.</p> <p>How can I change the way I have Tomcat 7 set up to allow the existing servlet application to access its database as "myDatabaseName"? I don't have the option of altering the code in the servlet application or altering the way WebLogic is set up on the test server. </p> <p><strong>I need to alter the way my copy of Tomcat 7 is set up on my computer ( for a dev environment ) to allow the servlet application to access its database in the style of the first chunk of quoted code at the top of this post.</strong></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
