    <p>I am trying to setup my application to receive files using Spring Integration (version 2.2.0.RELEASE). When I start Tomcat (where application is deployed), I get the following error message. Anyone has an idea why?</p> <pre><code>SEVERE: Error configuring application listener of class com.xxxx.aaa.web.mvc.context.CccccContextListener java.lang.NoClassDefFoundError: com/xxxx/bbb/application/core/exception/unchecked/InvalidFormatException at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Class.java:2389) at java.lang.Class.getConstructor0(Class.java:2699) at java.lang.Class.newInstance0(Class.java:326) at java.lang.Class.newInstance(Class.java:308) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4079) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4630) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1045) at org.apache.catalina.core.StandardHost.start(StandardHost.java:785) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1045) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:445) at org.apache.catalina.core.StandardService.start(StandardService.java:519) at org.apache.catalina.core.StandardServer.start(StandardServer.java:710) at org.apache.catalina.startup.Catalina.start(Catalina.java:581) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:289) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:414) Caused by: java.lang.ClassNotFoundException: com.xxxx.bbb.application.core.exception.unchecked.InvalidFormatException at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1645) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1491) ... 20 more </code></pre> <p>I believe the error message above is a red herring. Before adding the spring integration dependency to the pom file and having the ftp config file, Tomcat was starting successfully.</p> <p>I use Java6 and Tomcat6. My FTP config file is:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:int="http://www.springframework.org/schema/integration" xmlns:int-ftp="http://www.springframework.org/schema/integration/ftp" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/integration http://www.springframework.org/schema/integration/spring-integration-2.2.xsd http://www.springframework.org/schema/integration/ftp http://www.springframework.org/schema/integration/ftp/spring-integration-ftp-2.2.xsd"&gt; &lt;int:channel id="ftpChannel"&gt; &lt;int:queue/&gt; &lt;/int:channel&gt; &lt;bean id="ftpClientFactory" class="org.springframework.integration.ftp.session.DefaultFtpSessionFactory"&gt; &lt;property name="host" value="localhost" /&gt; &lt;property name="port" value="21" /&gt; &lt;property name="username" value="user" /&gt; &lt;property name="password" value="password" /&gt; &lt;/bean&gt; &lt;int-ftp:inbound-channel-adapter id="ftpInbound" channel="ftpChannel" filename-pattern="*.csv" session-factory="ftpClientFactory" auto-create-local-directory="true" delete-remote-files="true" remote-directory="/" local-directory="C:/folder/IN"&gt; &lt;int:poller fixed-rate="1000" max-messages-per-poll="15"/&gt; &lt;/int-ftp:inbound-channel-adapter&gt; &lt;/beans&gt; </code></pre> <p>I added dependency in the pom file as follows :</p> <pre><code>&lt;dependency&gt; &lt;groupId&gt;org.springframework.integration&lt;/groupId&gt; &lt;artifactId&gt;spring-integration-ftp&lt;/artifactId&gt; &lt;version&gt;2.2.0.RELEASE&lt;/version&gt; &lt;/dependency&gt; </code></pre> <p></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.

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).
