title: Orbeon - MySQL connection problem
body: <p>Orbeon was working well. The next step was to connect to a MySQL-database.</p>
  
  <p>I followed the following instructions on <a href="http://wiki.orbeon.com/forms/doc/developer-guide/form-runner/mysql-persistence-layer" rel="nofollow">http://wiki.orbeon.com/forms/doc/developer-guide/form-runner/mysql-persistence-layer</a></p>
  
  <ol>
  <li><p>Creation database + tables for the user "orbeon" and "orbeon" as a password</p></li>
  <li><p>Placed "mysql-connector-java-5.1.13-bin.jar" in "/etc/apache-tomcat-5.5.31/common/lib"</p></li>
  <li><p>Tested the jdbc-driver with the following instructions (MySQL DBCP Example on  tomcat.apache.org/tomcat-5.5-doc/jndi-datasource-examples-howto.html). this example worked fine, so I concluded that there is nothing wrong with the JDBC-driver.</p></li>
  <li><p>Added the following to "server.xml" in "etc/apache-tomcat-5.3.1/conf"</p>
  
  <pre><code>&lt;Context path="/orbeon" docBase="orbeon"
          debug="5" reloadable="true" crossContext="true"&gt;
  
  
     &lt;Resource name="jdbc/mysql" auth="Container" type="javax.sql.DataSource"
      initialSize="3" maxActive="10" maxIdle="20" maxWait="30000"
      driverClassName="com.mysql.jdbc.Driver"
      poolPreparedStatements="true"
      username="orbeon"
      password="orbeon"
      url="jdbc:mysql://localhost:3306/orbeon"/&gt;
  
  
  &lt;/Context&gt;
  </code></pre></li>
  <li><p>Created a new file "properties-local.xml" on "etc/apache-tomcat-5.3.1/webapps/orbeon/WEB-INF/config" and added the following line: </p>
  
  <p>&lt; property as="xs:anyURI"  name="oxf.fr.persistence.app.uri.<em>.</em>.*" value="/fr/service/mysql"/></p></li>
  </ol>
  
  <p>When I did a shutdown and restart from tomcat there is no problem, the problems start when I want to add data to an existing form or want to add a new form definition.</p>
  
  <p>I'm looking 4 hours on this allready and I can't solve it.</p>
  
  <p>Does someone knows the problem?</p>
  
  <p>Many thx.</p>
  
  <p>Koen</p>
