Intellij Idea 8 & Seam

I think that I found a clue:

http://www.theserverside.com/news/thread.tss?thread_id=46560

"Also, I found it quite simple to configure the output of POJO classed to /WEB-INF/dev for hot-swap of changed POJOs (yes, class structure change is supported here by seam)"

Any Idea how to configure my project on this way, cause I don't find it so simple.


Thanks in advance

Did you make it work?

I just found a suboptimal workaround, by changing the URI to 'WEB-INF/dev' in my .iml-file:

<containerElement type="module" name="%MODULE-NAME%">
             <attribute name="method" value="1" />
             <attribute name="URI" value="/WEB-INF/classes" />
</containerElement>

But everytime I re-import my maven files it's overriden by IDEA again. Not sure yet which maven setting to change to keep it.

What I also needed to for the workaround to function properly, I had to define an ant-task (in Maven) to copy the non-class files (e.g. persistence.xml) from the /dev folder to the /classes folder:
         <build>
                 <plugins>
                     <plugin>
                         <groupId>org.apache.maven.plugins</groupId>
                         <artifactId>maven-antrun-plugin</artifactId>
                         <configuration>
                             <tasks>
                                 <echo>Moving non-classes to /classes</echo>
                                 <move todir="${project.build.directory}/exploded/WEB-INF/classes"
                                       overwrite="true">
                                     <fileset dir="${project.build.directory}/exploded/WEB-INF/dev">
                                         <exclude name="**/*.class"/>
                                     </fileset>
                                 </move>
                             </tasks>
                         </configuration>
                     </plugin>
                 </plugins>
             </build>

I put this into a special 'dev'-profile in maven and call it once everytime I start Tomcat. This way all the class changes are directly hot deployed when doing Make instead of having an ant-task EVERY time I want to hot deploy.

PS: I get this error:
SEVERE: Exception sending context initialized event to listener instance of class org.jboss.seam.servlet.SeamListener
org.jboss.seam.InstantiationException: Could not instantiate Seam component: PU

Is there any easier way to enable compiling to WEB-INF/dev?

I have 4 source folders, one of which is for my hot-deployed classes. How can I set this source folder to compile to WEB-INF/dev so that Jboss will pick it up? I'm not using Maven.

Is this approach the recommended method : http://stackoverflow.com/questions/690676/achieving-seam-hot-deployment-with-intellij-idea

Thanks,

Damian.

Workaround is to use an Ant task to compile the classes and set it to run after compilation (right click on the Ant task -> Execute On -> After Compilation.)
