Question

我已经使用模型2（Shared J2EE Resource）在Tomcat 7中部署了Jackrabbit，但是当我尝试访问存储库时，我得到NamingException例外。

javax.naming.NamingException: Cannot create resource instance
  at org.apache.naming.factory.ResourceFactory.getObjectInstance(ResourceFactory.java:144)
  at javax.naming.spi.NamingManager.getObjectInstance(Unknown Source)
  at org.apache.naming.NamingContext.lookup(NamingContext.java:842)
  at org.apache.naming.NamingContext.lookup(NamingContext.java:153)
  at org.apache.naming.NamingContext.lookup(NamingContext.java:830)
  at org.apache.naming.NamingContext.lookup(NamingContext.java:167)

我的代码是：

InitialContext context = new InitialContext();
Context environment = (Context) context.lookup("java:comp/env");

// The exception is thrown in this line
Repository repository = (Repository) environment.lookup("jcr/repository");

我在Tomcat GlobalNamingResource中将此资源添加为server.xml：

<Resource name="jcr/globalRepository"
    auth="Container"
    type="javax.jcr.Repository"
    factory="org.apache.jackrabbit.core.jndi.BindableRepositoryFactory"
    configFilePath="C:\Users\vgomez\repository.xml"
    repHomeDir="C:\Users\vgomez\repository"/>

在context.xml我添加了ResourceLink：

<ResourceLink 
    name="jcr/repository"
    global="jcr/globalRepository"
    type="javax.jcr.Repository"/>

我的网络应用的web.xml是：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" 
    version="2.4">

    <display-name>Archetype Created Web Application</display-name>

    <resource-ref>
        <description>JCR Repository</description>
        <res-ref-name>jcr/repository</res-ref-name>
        <res-type>javax.jcr.Repository</res-type>
        <res-auth>Container</res-auth>
     </resource-ref>

</web-app>

编辑：当网络应用使用Vaadin时会出现此问题。例如，如果Web应用程序使用jsf，则此配置可用。

我发现了问题。我想我没有所需的所有依赖项。对于使用Book of Vaadin中给出的命令创建的Vaadin项目，这是pom.xml
