Question

我正在开发一个java项目，我必须与ejabberd（创建/删除jabber用户等）xmpp服务器进行通信。根据互联网上提供的不同建议，我理解xml rpc是实现这一目标的一种方法。

我尝试按照此主题中的建议安装mod_xmlrpc。 Error while starting ejabberd with xml_rpc

但是在配置mod_xmlrpc后我没能启动ejabberd。 ejabberd日志说，

=ERROR REPORT==== 2015-03-15 20:23:27 ===
C(<0.42.0>:gen_mod:75) : Problem starting the module mod_adhoc for host "example.com" 
 options: []
 exit: {noproc,
       {gen_server,call,
           [ejabberd_iq_sup,
        {start_child,["example.com",mod_adhoc,process_local_iq]},
        infinity]}}

=ERROR REPORT==== 2015-03-15 20:23:27 ===
C(<0.42.0>:gen_mod:80) : ejabberd initialization was aborted because a module start failed.

和erlang日志说，

因为我是ejabberd＆amp; amp;的新手。 erlang世界我发现很难找到根本原因。请帮我确定这次崩溃的根本原因。

BTW还有其他方法可以与java服务中的ejabberd（创建/删除jabber用户等）进行通信吗？

Answer 1

erlang日志说它在模块ejabberd_xmlrpc中找不到没有参数的函数socket_type。由于它是一个有效的调用，并且模块和函数都存在于应用程序ejabberd中，这意味着在安装过程中出现了错误（编译失败，错误的路径???）

在ejabberd中安装mod_xmlrpc后出错
