    <p>I was building the first project for OpenShift the PaaS. Decided to go with java so downloaded the JBoss Developer Studio and created the first poject. Openshift kind of already created the template so it should run. But in the developer studio, there is error:</p> <blockquote> <p>javax.servlet cannot be resolved</p> </blockquote> <p>I know this could be simple for Java EE people but my question is that for OpenShift, would the solution be same. Can we just copy an apache tomcat jar to the project folder? JBoss Develper Studio is not exactly Eclipse I guess? So I added the jar and the error disappeared. Then there is this warning:</p> <blockquote> <p>Classpath entry .. tomecat-7.0.42/lib/servlet-api.jar will not be exported or published ClassNotFoundException may result.</p> </blockquote> <p><strong>Question</strong></p> <p>What is the right thing for the error and warning to disappear? Should Openshift already have the jar since it's a PaaS, not IaaS. Do we just need the jar to build but this jar will not be part of the web app?</p> <p><strong>Info</strong></p> <p>The JBoss Developer Studio does have pom.xml</p> <pre><code>&lt;project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"&gt; &lt;modelVersion&gt;4.0.0&lt;/modelVersion&gt; &lt;groupId&gt;tom&lt;/groupId&gt; &lt;artifactId&gt;tom&lt;/artifactId&gt; &lt;packaging&gt;war&lt;/packaging&gt; &lt;version&gt;1.0&lt;/version&gt; &lt;name&gt;tom&lt;/name&gt; &lt;repositories&gt; &lt;repository&gt; &lt;id&gt;eap&lt;/id&gt; &lt;url&gt;http://maven.repository.redhat.com/techpreview/all&lt;/url&gt; &lt;releases&gt; &lt;enabled&gt;true&lt;/enabled&gt; &lt;/releases&gt; &lt;snapshots&gt; &lt;enabled&gt;true&lt;/enabled&gt; &lt;/snapshots&gt; &lt;/repository&gt; &lt;/repositories&gt; &lt;pluginRepositories&gt; &lt;pluginRepository&gt; &lt;id&gt;eap&lt;/id&gt; &lt;url&gt;http://maven.repository.redhat.com/techpreview/all&lt;/url&gt; &lt;releases&gt; &lt;enabled&gt;true&lt;/enabled&gt; &lt;/releases&gt; &lt;snapshots&gt; &lt;enabled&gt;true&lt;/enabled&gt; &lt;/snapshots&gt; &lt;/pluginRepository&gt; &lt;/pluginRepositories&gt; &lt;properties&gt; &lt;project.build.sourceEncoding&gt;UTF-8&lt;/project.build.sourceEncoding&gt; &lt;maven.compiler.source&gt;1.6&lt;/maven.compiler.source&gt; &lt;maven.compiler.target&gt;1.6&lt;/maven.compiler.target&gt; &lt;/properties&gt; &lt;dependencies&gt; &lt;dependency&gt; &lt;groupId&gt;org.postgresql&lt;/groupId&gt; &lt;artifactId&gt;postgresql&lt;/artifactId&gt; &lt;version&gt;9.2-1003-jdbc4&lt;/version&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;mysql&lt;/groupId&gt; &lt;artifactId&gt;mysql-connector-java&lt;/artifactId&gt; &lt;version&gt;5.1.25&lt;/version&gt; &lt;/dependency&gt; &lt;/dependencies&gt; &lt;profiles&gt; &lt;profile&gt; &lt;!-- When built in OpenShift the 'openshift' profile will be used when invoking mvn. --&gt; &lt;!-- Use this profile for any OpenShift specific customization your app will need. --&gt; &lt;!-- By default that is to put the resulting archive into the 'webapps' folder. --&gt; &lt;!-- http://maven.apache.org/guides/mini/guide-building-for-different-environments.html --&gt; &lt;id&gt;openshift&lt;/id&gt; &lt;build&gt; &lt;finalName&gt;tom&lt;/finalName&gt; &lt;plugins&gt; &lt;plugin&gt; &lt;artifactId&gt;maven-war-plugin&lt;/artifactId&gt; &lt;version&gt;2.1.1&lt;/version&gt; &lt;configuration&gt; &lt;outputDirectory&gt;webapps&lt;/outputDirectory&gt; &lt;warName&gt;ROOT&lt;/warName&gt; &lt;/configuration&gt; &lt;/plugin&gt; &lt;/plugins&gt; &lt;/build&gt; &lt;/profile&gt; &lt;/profiles&gt; &lt;/project&gt; </code></pre>

    1. COyeah... copying random `jar`s around is probably a bad idea. A `jar` is a compressed collection of `class` files.

    2. COlooks like he used external jars, otherwise, why the warning is pointing to another path? A newbie might have tried different things and forgot what finally made it to work. Normally the servlet-api.jar (tomcat) is part of the JBOSS server already. For developer, one just need to have it to compile.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
