Good morning / afternoon,

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).

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;
}

Here is the log :

Thanks for all.

    I found the solution ^^

    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.

    I add to my felix-config.properties

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

    And 

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

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

    Thanks for your help.
