    <p>I suspect that this may be some sort of versioning issue, but still can not get to the bottom of it. I am trying to set up a play2.1/storm project in Scala 2.10, with a Scala DSL based on <a href="https://github.com/velvia/ScalaStorm" rel="nofollow">https://github.com/velvia/ScalaStorm</a>. I copied and edited the DSL files into my project. My problem arises when trying to implement the WordCountTopology example from the same project. A direct copy/paste of the example compiles fine, and eclipse doesn't complain about anything, but when running the main function, I get classNotFoundExceptions</p> <p>The classes are clearly defined, and commenting out the lines that use them (the builder.setSpout and builder.setBolt lines) and just creating new objects of the ClassNotFound classes (RichStormSpout, WordCount, SplitSentence), though it doesn't do anything, compiles and runs just fine.</p> <p>Any help is much appreciated</p> <p>edit: here is a stack trace: </p> <pre><code>│java.lang.RuntimeException: java.lang.ClassNotFoundException: storm.WordCount │ at backtype.storm.utils.Utils.deserialize(Utils.java:70) ~[storm-0.8.2.jar:na] │ at backtype.storm.utils.Utils.getSetComponentObject(Utils.java:199) ~[storm-0.8.2.jar:na] │ at backtype.storm.daemon.task$get_task_object.invoke(task.clj:56) ~[storm-0.8.2.jar:na] │ at backtype.storm.daemon.task$mk_task_data$fn__3766.invoke(task.clj:158) ~[storm-0.8.2.jar:na] │ at backtype.storm.util$assoc_apply_self.invoke(util.clj:731) ~[storm-0.8.2.jar:na] │ at backtype.storm.daemon.task$mk_task_data.invoke(task.clj:152) ~[storm-0.8.2.jar:na] │Caused by: java.lang.ClassNotFoundException: storm.WordCount │ at java.net.URLClassLoader$1.run(URLClassLoader.java:202) ~[na:1.6.0_35] │ at java.security.AccessController.doPrivileged(Native Method) ~[na:1.6.0_35] │ at java.net.URLClassLoader.findClass(URLClassLoader.java:190) ~[na:1.6.0_35] │ at java.lang.ClassLoader.loadClass(ClassLoader.java:306) ~[na:1.6.0_35] │ at java.lang.ClassLoader.loadClass(ClassLoader.java:247) ~[na:1.6.0_35] │ at sbt.PlayCommands$$anonfun$53$$anonfun$55$$anon$2.loadClass(PlayCommands.scala:535) ~[na:na] </code></pre>

    1. COYou are running this in a play application, how are you kicking everything off? I'm confused in reading your description, it said you are running a main function.

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.
