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，我得到了 NamingException 异常。
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");
我将此资源作为 GlobalNamingResource 添加到我的 Tomcat server.xml 中:
<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 中，我添加了 ResourceLink:
<ResourceLink
name="jcr/repository"
global="jcr/globalRepository"
type="javax.jcr.Repository"/>
我的网络应用程序的 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:当网络应用程序使用 Vaadin 时会出现此问题。例如，如果 Web 应用程序使用 jsf，则此配置有效。
最佳答案
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
