JAXBContext Managing

Question

I have to generate a lot of xml snippets and store the into my database for later (re-)use. JaxB works fine, but i some questions came up:

1. Should i have one JAXBContext for the whole application or for each response dto one? I would keep the context in a static variable in each root dto object. (initialized once)
2. Is there no way to inject an marshaller in JEE6?

I want to keep the boilerplate code as small as possible.

greetings m

PS: XStream worked fine too, but i want to stick to the standards.

Answer 1

• Yes, you need only one JAXBContext

• You can always inject marshaller. (Best way is to use Spring)

   <bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
       <property name="classesToBeBound">
          <list>
              <value>com.package.YourClass</value>
           </list>
      </property>
  </bean>
  

I don't properly understand what you mean be "sticking to standards", but you could give a look at JIBX. It generally provides better performance than JaxB
