Wiki Example leads to 'Cannot create JDBC driver of class'

[bwagner]

I tried to get the SDK CustomComponent example to work which fails with a Authentication Exception. Since I need a JCR Query instead of Lucene based, I subclassed SearchBasedListConstraint to do a JCR Query and use this new class in my constraint in the model file.

   <constraints>
     <constraint name="my:customConstraint"
       type="org.alfresco.sample.constraints.JCRSearchBasedListConstraint">
       <parameter name="query">
         <value> TYPE:"{http://www.alfresco.org/model/content/1.0}content"
         </value>
       </parameter>
       </constraint>
   </constraints>
‍‍‍‍‍‍‍‍‍‍‍

use new model and class in *-context.xml to be bootstrapped

   <bean id="JCRSearchBasedListConstraintInitializer" 
      class=""org.alfresco.sample.constraints.JCRSearchBasedListConstraint"> 
   </bean>

    <!– Registration of new models –>   
    <bean id="extension.dictionaryBootstrap" parent="dictionaryModelBootstrap" depends-on="dictionaryBootstrap">
        <property name="models">
            <list>
                <value>alfresco/extension/exampleModel.xml</value>
            </list>
        </property>
    </bean>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍

and in my JCRSearchBasedListConstraint.java try to get the context as described in wiki http://wiki.alfresco.com/wiki/Introducing_the_Alfresco_Java_Content_Repository_API#Programmatically

final ApplicationContext context = new ClassPathXmlApplicationContext("classpath:alfresco/application-context.xml");
‍‍‍

this line already leads to the following error

i've also tried the second mentioned approach with injection, but with no results either

<bean id="myBean" class="myBeanImplementation">
  <property name="JCRRepository"><ref bean="JCR.Repository"/></property>
  …
</bean>
‍‍‍‍‍‍

hints very appreciated

bump;
I am having this same issue, only after doing a Community 3.3 to Enterprise 3.3 move. Non-JAR webscripts work fine. I assume this to be a no brainer, yet I cannot find any documentation out of two days of search. Any insight?

[premium93]

Thinking this would be in relationship the the retrieval of the ApplicationContext.

I tried:

import org.alfresco.util.ApplicationContextHelper;‍

// SLIDE_DEPOT_PROP_MAP.get(MAP_IDX_CLASSPATH_XML_APP_CONTEXT) is the same thing as "classpath:alfresco/application-context.xml"
// ApplicationContext context = new ClassPathXmlApplicationContext(SLIDE_DEPOT_PROP_MAP.get(MAP_IDX_CLASSPATH_XML_APP_CONTEXT));
ApplicationContext context = ApplicationContextHelper.getApplicationContext();‍‍‍‍

Not Successfull!

[premium93]

Update:

Alfresco 3.3 moves to a new set of definitions, porting to Spring.

It's not good to use ApplicationContext as this opens multiple instances of Alfresco. It's recommended to use WebServiceFactory and use Alfresco Services to retrieve Nodes instead.

Hi,

Any updates on this? Examples on how to initialize services when using java API?
I've understood that you cant use ApplicationCOntext now.
