the easycwmp works fine with another Xasc server. And the openacs with tomcat works fine with other cwmp client. So I do not think there is problem on our easycwmp client or the openacs.(I cant get the log of the server) Is that possible there is something incompatible between client and server, such as http header.
Expecting your response, thanks a lot.

I spent lots of time to compare the ok message from other ok client with the message from our easycwmp. Finally I find two key points to solve the code 500 problem.(code 500 alwasy means format error in the easycwmp case)
 Firstly, the version of tr069 in easycwmp shows in "xmlns:cwmp=urn:dslforum-org:cwmp-1-2", but the server just support "xmlns:cwmp=urn:dslforum-org:cwmp-1-0".For compatible, maybe it's better for you to change the version of tr069 to cwmp-1-0.
 Secondly, the soap envelop:
#define CWMP_INFORM_MESSAGE \
"<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?>" \
  "<soap_env:Envelope " \
    "xmlns:soap_env=\"http://schemas.xmlsoap.org/soap/envelope/\" [^] " \
    "xmlns:soap_enc=\"http://schemas.xmlsoap.org/soap/encoding/\" [^] " \
    "xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" [^] " \
    "xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" [^] "\
    "xmlns:cwmp=\"urn:dslforum-org:cwmp-1-0\">"
   ...
the server didn't support the line break(LF) in element. But I didn't find anywhere in the code add the LF after load with:
   mxml_node_t *tree = mxmlLoadString(NULL, CWMP_INFORM_MESSAGE,MXML_NO_CALLBACK);
I caught from the message was (add the (LF) for easy understand ):
  <?xml version="1.0" encoding="UTF-8" standalone="no"?>
 <soap_env:Envelope (LF)
xmlns:soap_env="http://schemas.xmlsoap.org/soap/envelope/" [^] (LF)
xmlns:soap_enc="http://schemas.xmlsoap.org/soap/encoding/" [^] (LF)
xmlns:xsd="http://www.w3.org/2001/XMLSchema"(LF) [^]
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"(LF) [^]
xmlns:cwmp="urn:dslforum-org:cwmp-1-0"> (LF)
...

I write a FUNC to solve this. Any advice about the root cause problem.
