Context We have this application, using about 60 coding projects. We have several products that are realized using this same code base, so we follow the maven best-practices : we assemble each product using an assembly project, using the assembly plugin. We have an historical assembly using Ant, that need many improvements. In a firs...

Hello. Where I work, we have a policy in place that states we should try to build web services "bottom-up" (code-first). When doing this, how can I add restrictions within my XSD <types> WSDL element? For example, in the following: import javax.jws.WebService; import javax.xml.ws.BindingType; @WebService @BindingType(javax.xml.ws.soa...

I annotated a XmlAdapter class like so: @XmlTransient public class DateTimeXmlAdapter extends XmlAdapter<String, DateTime> { but schemagen.exe generates <xs:complexType name="xmlAdapter" abstract="true"> <xs:sequence/> </xs:complexType> so does't skip the class, which was what I expected. XmlAdapter indeed is an abstract clas...

I'm looking for a reputable Java implementation of a topological sort, given a directed graph of dependencies (node #7 depends on node #2, node #2 depends on note #4, etc.), that will detect the presence of a cycle so I can report an error if a cycle occurs. I assume Apache ant has to do this so I'm hoping I could just make use of it, b...

I must be really stupid, but I'm at my wits' end with a JPA issue, using MyEclipse 7.5. I am accessing a DB2 database (on an AS400) via JPA. I have reverse-engineered a simple table to provide a DAO with some precision "find" methods. So far so good. If I run a SELECT statement over the table thus, I get 4 rows: SELECT * FROM MyTable ...
