com.sun.jndi.ldap.LdapCtxFactory:在servlet中找不到类 [英] com.sun.jndi.ldap.LdapCtxFactory : class not found in servlet

问题描述

早上好/下午

我在LDAP连接器中遇到问题，当我在单元测试中使用它时没有问题，但是在应用程序服务器环境中调用它时，似乎存在类路径问题，但是该类是通过Java 1.6.17传递的(我使用的版本).

I have a problem with LDAP connector, when I use it in my unit test no problem, but when it was called in a application server environment, it seems to have classpath issue, but this class is delivred with java 1.6.17 (version I use).

我使用spring-ldap来启动连接.

I use spring-ldap to initiate my connection.

public static LdapContextSource getLdapContextSource(final String url, final String base) throws Exception {
    LdapContextSource ldapContextSource = new LdapContextSource();

    ldapContextSource.setUrl(url);
    ldapContextSource.setBase(base);
    ldapContextSource.setPooled(true);
    //ldapContextSource.setContextFactory(LdapCtxFactory.class);

    ldapContextSource.afterPropertiesSet();

    return ldapContextSource;
}

这是日志:

谢谢大家. 问候.

推荐答案

我找到了解决方案^^

I found the solution ^^

这是Jonas 5的问题，它是在OSGI平台上运行的应用服务器. 我的应用程序是一个普通的核心jar(包含带有DAO的spring上下文)，共3次战争.看来，用于托管公共内核的JVM与用于3次大战的JVM不同.

It was a problem with Jonas 5 wich is an app server running on OSGI platform. My application is a common core jar (containing spring context with DAO) shared by 3 wars. It seems that the JVM used to host the common core is not the same as used for the 3 wars.

我将其添加到felix-config.properties

I add to my felix-config.properties

org.osgi.framework.bootdelegation=....
    sun.util.calendar; \
    com.sun.jndi.ldap; \
    version="1.5.0"

还有

org.osgi.framework.bootdelegation=com.sun.corba, \
....
com.sun.jndi.ldap.*

这样我就可以在我的Common Core中加载com.sun.jndi.ldap.LdapCtxFactory.

So that I can load com.sun.jndi.ldap.LdapCtxFactory in my Common Core.

感谢您的帮助.
