netstat -pMac OSX 10.8 and earlier doesn't support switch '-p' in netstat command. However there is simple workaround. There is command 'lsof' which list open files and their process ids. You can list processes which are listening like this:
lsof -i | grep LISTENIt's useful to see port number instead of service name running on such port. It's better to see :8080 instead of 'http-alt'. It could be done like this:
lsof -i -P | grep LISTEN
I met following exception during changing hibernate mapping. I'm using hibernate 3.2
Caused by: org.hibernate.MappingException: Repeated column in mapping for entity: cz.koroptev.cubiculus.core.model.Brick column: id_shape (should be mapped with insert="false" update="false") at org.hibernate.mapping.PersistentClass.checkColumnDuplication(PersistentClass.java:605) at org.hibernate.mapping.PersistentClass.checkPropertyColumnDuplication(PersistentClass.java:627) at org.hibernate.mapping.PersistentClass.checkColumnDuplication(PersistentClass.java:645) at org.hibernate.mapping.PersistentClass.validate(PersistentClass.java:420) at org.hibernate.mapping.RootClass.validate(RootClass.java:192) at org.hibernate.cfg.Configuration.validate(Configuration.java:1026) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1211) at cz.koroptev.cubiculus.core.services.impl.HibernateManagerServiceImpl.Problem was in inconsistent mapping of relations ship between objects 'Shape' and 'Brick'. Object 'Shape' contain set of bricks mapped as:(HibernateManagerServiceImpl.java:28) ... 47 more
<set name="bricks" lazy="true" order-by="id_brick" > <key column="id_shape" not-null="true" /> <one-to-many class="Brick" /> </set>and 'Brick' contains mapping to 'Shape'
<many-to-one name="shape" class="Shape" column="id_shape" foreign-key="brick_shape" not-null="false" />Problem is that in first mapping is column 'id_shape' mapped as not-null="true" and in second is mapped as not-null="false". This lead to mentioned exception.

Strange exception in other words say that it's not possible to find application template for some component. This problem shows just at production server not at my development machine. I'm using Tapestry 5 version 5.3.2.
After some time I found that problem was in directory naming. Templates in maven project are in directory 'src/main/webapps/buildinInstruction'. Name 'buildinInstruction' contains upper case I. When I change it to lower case problem disappears. Problem can't be reproduced at my machine because my Mac OS X use case insensitive file system.

Problem is in maven project info plugin version. When version is 2.1 or lover problem disappears.
Plugin could be configured like this:
<project>
...
<reporting>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-project-info-reports-plugin</artifactId>
<version>2.1</version>
...
</plugin>
...
</plugins>
</reporting>
...
</project>
Root of the problem is in version of module doxia-sink-api module which is different in both versions of project info plugin version. In version 1.1 is doxia-sink-api-1.0-alpha-11 and in version 2.2 is doxia-sink-api-1.2.
When you have in pom file dependency on javadoc plugin which itself contains dependency on doxia-sink-api-1.0-alpha-11 than in runtime doxia-sink-api version in project-info-plugin is overridden by version of doxia-sink-api from java doc plugin. So another solution is to upgrade java doc plugin or maven site plugin.
