jackRabbit helloworld示例需要帮助

Question

我是JackRabbit的新手，我正在尝试运行FirstHop.java，但是我遇到了以下错误。

代码

import javax.jcr.Repository; 
import javax.jcr.Session; 
import org.apache.jackrabbit.core.TransientRepository; 

public class FirstHop { 

    public static void main(String[] args) throws Exception 
    {

        Repository repository = (Repository) new TransientRepository(); 
        Session session = repository.login(); 
        try 
        { 
            String user = session.getUserID(); 
            String name = repository.getDescriptor(Repository.REP_NAME_DESC); 
            System.out.println( 
            "Logged in as " + user + " to a " + name + " repository."); 
        } 
        finally 
        { 
            session.logout(); 
        } 
    } 
} 

log4j:WARN No appenders could be found for logger (org.apache.jackrabbit.core.TransientRepository).
log4j:WARN Please initialize the log4j system properly.

我用的是下面的罐子。

1. commons-dbcp-1.2.jar
2. commons-pool-1.5.jar
3. jackrabbit-api-2.3.5.jar
4. jackrabbit-core-2.4.2.jar
5. jackrabbit-jcr-commons-2.3.5.jar
6. jackrabbit-spi-2.1.3-.jar
7. jackrabbit-spi-2.3.5.jar
8. jackrabbit-spi-commons-2.3.5.jar
9. 野兔-独立-1.5.0.jar 10.jcr-2.0.jar 11.org.apache.sling.jcr.jackrabbit.api-2.0.2-incubator.jar

谢谢。

你只需要杰克比-独立的罐子。在多个jars中存在相同的类定义时，会发生多个冲突。此外，在使用Jack兔子时，还存在版本不匹配的问题，因为许多功能已经从1.5更改为2.4。

我只运行了同样的程序，一个独立的罐子。
