    copied!<p>I´m getting a little bit lost in my own (maven enabled) dynamic WEB - Project. The project works fine, I´ve got a RESTful WebService (Jersey) running and I´m able to consume it.</p> <p>... my next step was to persist my domain classes, with Spring Data and Neo4j. So, I´ve added some tags to my pom.xml</p> <pre><code>... &lt;repository&gt; &lt;id&gt;spring-milestone&lt;/id&gt; &lt;name&gt;Spring Maven MILESTONE Repository&lt;/name&gt; &lt;url&gt;http://maven.springframework.org/milestone&lt;/url&gt; &lt;/repository&gt; &lt;dependency&gt; &lt;groupId&gt;org.springframework.data&lt;/groupId&gt; &lt;artifactId&gt;spring-data-neo4j&lt;/artifactId&gt; &lt;version&gt;2.0.0.RELEASE&lt;/version&gt; &lt;/dependency&gt; ... </code></pre> <p>my next step was to annotate my entity-classes... here is a simple example:</p> <pre><code>... @NodeEntity public class Category { @GraphId Long nodeId; String categoryType; public Category(String categoryType){ this.categoryType = categoryType; } } ... </code></pre> <p>okay, everything´s fine... now I want to persist my category-object...</p> <pre><code>@Autowired Neo4jTemplate template; @Test @Transactional public void toGraphDb() { template.save(new Category("mashineCategory")); } </code></pre> <p>when I run the test I´m getting a NullPointerException, cause the template is null</p> <p>I guess there is something missing in my project, but I´m not sure in which folder/file to add informations/files...</p> <p>here is my web.xml:</p> <pre><code>... &lt;display-name&gt;ElisaSimulatorM4&lt;/display-name&gt; &lt;servlet&gt; &lt;servlet-name&gt;Jersey REST Service&lt;/servlet-name&gt; &lt;servlet-class&gt;com.sun.jersey.spi.container.servlet.ServletContainer&lt;/servlet-class&gt; &lt;init-param&gt; &lt;param-name&gt;com.sun.jersey.config.property.packages&lt;/param-name&gt; &lt;param-value&gt;de.elisa.communication.webservice.restservice.implementation&lt;/param-value&gt; &lt;/init-param&gt; &lt;load-on-startup&gt;1&lt;/load-on-startup&gt; &lt;/servlet&gt; &lt;servlet-mapping&gt; &lt;servlet-name&gt;Jersey REST Service&lt;/servlet-name&gt; &lt;url-pattern&gt;/rest/*&lt;/url-pattern&gt; &lt;/servlet-mapping&gt; ... </code></pre> <p>in some guides I read something about dispatcherServlets and an applicatonContext.xml, but I have no idea where to put it in my project.</p> <p>Maybe someone can help me out...</p> <p>Ps. I wanted to upload a screenshot from my project-tree but as a greenhorn I haven't got enough reputation... sorry for that</p>
