    copied!<p>I have built a little model using Roo. There are 6 objects in the model that have various relationships - it was neat, it took like 20 minutes! Now that I have it, I want to create Spring MVC project and use the domain model - but I want to keep the web project totally separate from the Roo project (I don't understand Spring MVC to use the scaffolding in Roo yet).</p> <p>So I've created the dependency in the pom.xml of the web project and I can build and deploy the web project using 'mvn tomcat:run'. However, when the web tries to use the Spring Roo objects I get exceptions like this:</p> <pre><code>java.lang.IllegalStateException: Entity manager has not been injected (is the Spring Aspects JAR configured as an AJC/AJDT aspects library?) at com.loquatic.clcmops.consignortool.entities.Consignor_Roo_Jpa_ActiveRecord.entityManager_aroundBody0(Consignor_Roo_Jpa_ActiveRecord.aj:19) at com.loquatic.clcmops.consignortool.entities.Consignor_Roo_Jpa_ActiveRecord.ajc$interMethod$com_loquatic_clcmops_consignortool_entities_Consignor_Roo_Jpa_ActiveRecord$com_loquatic_clcmops_consignortool_entities_Consignor$entityManager(Consignor_Roo_Jpa_ActiveRecord.aj:1) at com.loquatic.clcmops.consignortool.entities.Consignor.entityManager(Consignor.java:1) </code></pre> <p>I have done this in a standalone project for a project where I had a class that had a main() method and I had to add a line of code to get the context loaded correctly (this basically: <a href="https://stackoverflow.com/questions/3284496/how-to-use-junit-tests-with-spring-roo-problems-with-entitymanager">How to use JUnit tests with Spring Roo? (Problems with EntityManager)</a> ). This being Spring MVC I sort of assumed it was happening automagically - I am obviously mistaken.</p> <p>So do I need to do something in the web project to get the context loaded for the Roo jar file? Or do I need to change something in the roo jar file project? Do I need annotate a controller with something to make this happy? </p> <p>I've tried adding the following to the pom.xml in the web project:</p> <pre><code> &lt;dependency&gt; &lt;groupId&gt;org.springframework&lt;/groupId&gt; &lt;artifactId&gt;spring-aop&lt;/artifactId&gt; &lt;version&gt;${org.springframework-version}&lt;/version&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;org.springframework&lt;/groupId&gt; &lt;artifactId&gt;spring-aspects&lt;/artifactId&gt; &lt;version&gt;${org.springframework-version}&lt;/version&gt; &lt;/dependency&gt; </code></pre> <p>and</p> <pre><code> &lt;dependency&gt; &lt;groupId&gt;org.aspectj&lt;/groupId&gt; &lt;artifactId&gt;aspectjrt&lt;/artifactId&gt; &lt;version&gt;${org.aspectj-version}&lt;/version&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;org.aspectj&lt;/groupId&gt; &lt;artifactId&gt;aspectjweaver&lt;/artifactId&gt; &lt;version&gt;${org.aspectj-version}&lt;/version&gt; &lt;/dependency&gt; </code></pre> <p>But that hasn't changed anything - and this is some serious guess work, too. </p> <p>Anyone have any pointers? How are you supposed to use a Spring domain model in another project that isn't necessarily a Roo project?</p> <p>Thanks!</p>
