GMLC MLP did not understand dtd file #12

Closed nhanth87 closed 8 years ago

nhanth87 commented 8 years ago

MLP required jibx to convert xsd to object. However something missing that it can't find xsd object and refer to dtd (which is not correct)

Hi Tran,

Hmmm, that looks like it's actually just complaining about the request containing invalid XML?

Can you provide more detailed information about exactly what you're trying? What's your request XML?

There are indeed some relevant XSD files here: gmlc/core/slee/sbbs/src/main/config

There are referenced by jibx here: gmlc/core/slee/sbbs/pom.xml

                    <configuration>
                        <includeSchemas>
mlp_svc_result_310.xsd mlp_svc_init_310.xsd 
                        </includeSchemas>
                    </configuration>

Now I did at one point convert those from DTD files, so the DTDs do exist, but in my testing they weren't required and everything worked fine without them, although I suppose it's possible something in the jibx error handling might be trying to find them it seems.

Cheers, Andrew

Hi Andrew, Nice to meet you here,

The problem happen just by sending a MLP request: Create a request file demo.txt with content:

<?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE svc_init SYSTEM "MLP_SVC_INIT_310.dtd">
 <svc_init xmlns="MLP_SVC_INIT_310.dtd">
   <hdr>
     <client>
       <id>USERNAME</id>
       <pwd>PASSWORD</pwd>
       <serviceid>SERVICEID</serviceid>
     </client>
   </hdr>
   <slir>
     <msids>
       <msid type="MSISDN">12345</msid>
     </msids>
     <eqop>
        <resp_timer>15</resp_timer>
     </eqop>
   </slir>
 </svc_init>

then use curl -X POST http://ip:8080/restcomm and the problem happen (telestax changed /mobicents to /restcomm due to rebrand)

I have do debugging and the problem is here: org.oma.protocols.mlp.svc_init.SvcInit svcInit = (org.oma.protocols.mlp.svc_init.SvcInit)unmarshaller.unmarshalDocument(requestStream, "UTF-8");

But no way to jump into this function to know what's the root cause Please advice me what I need to do to solve it

BR, TN

Hi Tran,

I'm not sure if that's just an e-mail client paste error or not?

Your request XML should look more like this, does it?

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE svc_init SYSTEM "MLP_SVC_INIT_310.dtd">

USERNAME PASSWORD SERVICEID MSISDN OF TARGET 15

I suspect it's something like due to malformed XML, jibx is trying to process the specified DTD file and not finding it, so we may need to find a way to point jibx at the DTD in order to allow for proper error handling anyway, but the root cause should just be that you're feeding bad XML into the system. Of course even if you get it to work, we should still make a note and get the error handling fixed. I'll try to help take a look soon when I can.

Cheers, Andrew

Hi Andrew, I downloaded 12 DTD files from OMA and put it in bin directory and it work. However, GMLC will read 12 files every request and it went bad in case 1000 request/s, we are burning our hard disk.

I take a note and will comeback asap with this.
