    <p>I'm using hibernate 4.1.2 in a project based on struts framework 2.3.3 with tomcat 7.0.26. I'm also using mysql (and postgres) for my tests. This is my hibernate.cfg.xml with MySql:</p> <pre><code>&lt;session-factory&gt; &lt;property name="c3p0.min_size"&gt;5&lt;/property&gt; &lt;property name="c3p0.max_size"&gt;20&lt;/property&gt; &lt;property name="c3p0.timeout"&gt;300&lt;/property&gt; &lt;property name="c3p0.max_statements"&gt;50&lt;/property&gt; &lt;property name="c3p0.idle_text_period"&gt;3000&lt;/property&gt; &lt;property name="show_sql"&gt;true&lt;/property&gt; &lt;property name="connection.driver_class"&gt;com.mysql.jdbc.Driver&lt;/property&gt; &lt;property name="connection.url"&gt;jdbc:mysql://localhost/struts2&lt;/property&gt; &lt;property name="connection.username"&gt;semperEst&lt;/property&gt; &lt;property name="connection.password"&gt;*******&lt;/property&gt; &lt;property name="dialect"&gt;org.hibernate.dialect.MySQL5InnoDBDialect&lt;/property&gt; &lt;!-- Enable Hibernate's automatic session context management --&gt; &lt;property name="current_session_context_class"&gt;thread&lt;/property&gt; &lt;!-- Disable the second-level cache --&gt; &lt;property name="cache.provider_class"&gt;org.hibernate.cache.NoCacheProvider&lt;/property&gt; &lt;!-- Drop and re-create the database schema on startup --&gt; &lt;property name="hbm2ddl.auto"&gt;create-drop&lt;/property&gt; &lt;mapping class="firstname.secondname.lesson2.User"/&gt; &lt;/session-factory&gt; </code></pre> <p>My WEB-INF/lib contains: </p> <pre><code>antlr-2.7.7.jar asm-3.3.jar asm-commons-3.3.jar asm-tree-3.3.jar commons-fileupload-1.2.2.jar commons-io-2.0.1.jar commons-lang-2.4.jar commons-lang3-3.1.jar dom4j-1.6.1.jar freemarker-2.3.19.jar hibernate-commons-annotations-4.0.1.Final.jar hibernate-core-4.1.2.Final.jar hibernate-jpa-2.0-api-1.0.1.Final.jar javassist-3.11.0.GA.jar javassist-3.15.0-GA.jar jboss-logging-3.1.0.GA.jar jboss-transaction-api_1.1_spec-1.0.0.Final.jar log4j-1.2.16.jar mysql-connector-java-5.1.20-bin.jar ognl-3.0.5.jar postgresql-9.1-902.jdbc4.jar slf4j-api-1.6.4-sources.jar slf4j-log4j12-1.6.4.jar struts2-core-2.3.3.jar xwork-core-2.3.3.jar </code></pre> <p>*<strong>I've already added mysql-connector-java-5.1.20-bin.jar in $CATALINA_HOME/lib*</strong></p> <p>but I still have this exception: </p> <p><em><strong>java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost/struts2</em></strong> at java.sql.DriverManager.getConnection(DriverManager.java:604)</p> <pre><code> at java.sql.DriverManager.getConnection(DriverManager.java:190) at org.hibernate.service.jdbc.connections.internal.

    1. COi don't see any reason not working with S2 as S2 is out of the context here. see https://forum.hibernate.org/viewtopic.php?p=2454336 and https://hibernate.onjira.com/browse/HHH-7169

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).
