我们正在努力的是一个简单的Xpage解决方案。此工具的目标是从我们的LDAP获取个人信息（全名和公司），其他功能是更改密码（密码重置）。 这是我的java类

在faces-config代码中我们定义

<faces-config>
<managed-bean>
<managed-bean-name>emailBean</managed-bean-name>
<managed-bean-class>com.ibm.xsp.utils.EmailBean</managed-bean-class>

</managed-bean>
<!--AUTOGEN-START-BUILDER: Automatically generated by IBM Domino Designer. Do not modify.-->
<!--AUTOGEN-END-BUILDER: End of automatically generated section-->
</faces-config>
在Xpage中我定义了一个字段和一个按钮（此按钮将使用jave类从LDAP结构中获取信息）
该按钮包含以下代码
importPackage(com.mycompany.utils);
var UID = document1.getItemValueString("UID");
print(" ");
print(" ");
print("From xpages");
try{
var ldapConnection = new LDAP();
}catch(e){
print("Error generating dynamic LDAP: " + e.toString());
}
print("+=========================================1");
print (UID);
/*ldapConnection.searchForUID(UID);
if(ldapConnection.getFound()){
print("User :"+ldapConnection.getFirstNameAttr()+" "+ldapConnection.getLastNameAttr());
print("Company :"+ldapConnection.getTerCustCompanyName());
print("Passsword :"+new String(ldapConnection.getUserPassword(), StandardCharsets.UTF_8));
return ldapConnection.getTerCustCompanyName();
}else{
print("user not found!");
}*/
print("+=========================================2");
print(" ");
print(" ");
print("END xpages");
最后，当我们执行按钮时，我们会在控制台中收到以下消息。

感谢您的帮助。 最诚挚的问候

Apache Mina为LDAP连接创建了一个新线程，但使用了XPage引擎的类加载器。创建新线程时，此类加载器会检查是否存在NotesContext，而未对新线程进行初始化。这就是它失败的原因。
