web services - Trying to find out why one of those two SOAP requests does not work (java.lang.IllegalArgumentException) -

i have running jax-ws webservice has working endpoints. i'm having following issue:

i'm having 2 different soap requests here , don't understand why first 1 works second 1 not.

the obvious difference in requests first 1 specifies namespace in <envelope> tag while second 1 specifies when calling method <getmolddatahistory>.

soap request 1 - not working (namespace specified @ method call)

<s:envelope     xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" >     <s:body         xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"         xmlns:xsd="http://www.w3.org/2001/xmlschema"     >         <getmolddatahistory             xmlns="http://history.production.soap.webservices.product.company.at/">             <machineid>92623-15853588</machineid>             <start>0</start>             <end>0</end>         </getmolddatahistory>     </s:body> </s:envelope> 

soap request 2 - working (namespace specified in <envelope> tag)

<soapenv:envelope      xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"      xmlns:his="http://history.production.soap.webservices.product.company.at/">     <soapenv:header/>     <soapenv:body>       <his:getmolddatahistory>          <machineid>92623-15853588</machineid>          <start>0</start>          <end>0</end>       </his:getmolddatahistory>    </soapenv:body> </soapenv:envelope> 

the soap error message i'm getting when making first (not working) request.

<s:envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">    <s:body>       <s:fault xmlns:ns4="http://www.w3.org/2003/05/soap-envelope">          <faultcode>s:server</faultcode>          <faultstring>java.lang.illegalargumentexception</faultstring>       </s:fault>    </s:body> </s:envelope> 

the stacktrace of exception thrown server when receiving first soap request.

so i'm trying figure out why first request not working despite being valid soap request. there need configure @ server allow such requests?

edit:

after doing more testing found out position of namespace declaration not matter if method call has 0 parameters. parameter required stops working.

edit 2:

now stumpled upon this thread here . have same issue. c# client makes requests not use namespace int method tag. after add it works.

still how can tell jax-ws deal this.

does not work:

<getmolddatahistory xmlns="http://history.production.soap.webservices.product.company.at/"> 

works:

<his:getmolddatahistory xmlns:his="http://history.production.soap.webservices.product.company.at/"> 

when using prefix bound namespace in

<his:getmolddatahistory xmlns:his="http://history.production.soap.webservices.product.company.at/">     <machineid>92623-15853588</machineid>     <start>0</start>     <end>0</end> </his:getmolddatahistory> 

then element getmolddatahistory put specified namespace. reason syntax xmlns:his="..." declares prefix. must used @ all elements want in specified namespace. in code snippet, element getmolddatahistory.

using xmlns="..." syntax in

<getmolddatahistory xmlns="http://history.production.soap.webservices.product.company.at/">     <machineid>92623-15853588</machineid>     <start>0</start>     <end>0</end> </getmolddatahistory> 

not declares namespace, puts associated element , all child elements namespace.

conclusion: these 2 xml snippets not semantically equivalent.

if there such thing "expanded element name" syntax, these xml snippets ...

first one:

<{http://history.production.soap.webservices.product.company.at/}getmolddatahistory>     <{}machineid>92623-15853588</{}machineid>     <{}start>0</{}start>     <{}end>0</{}end> </{http://history.production.soap.webservices.product.company.at/}getmolddatahistory> 

second one:

<{http://history.production.soap.webservices.product.company.at/}getmolddatahistory>     <{http://history.production.soap.webservices.product.company.at/}machineid>92623-15853588</{http://history.production.soap.webservices.product.company.at/}machineid>     <{http://history.production.soap.webservices.product.company.at/}start>0</{http://history.production.soap.webservices.product.company.at/}start>     <{http://history.production.soap.webservices.product.company.at/}end>0<{/http://history.production.soap.webservices.product.company.at/}end> </{http://history.production.soap.webservices.product.company.at/}getmolddatahistory>
