I am developing a Java program in Eclipse, to send Nfse to Camaquã. XML is signed and sent, but returns this error in java:
"Exception: Character string reference was not defined as a character string instance. Parameter name: s"
I have no idea what causes this error and would like to know if anyone could help me. Entire log of the bug as Debugger:

This error definitely seems to be coming from the webservice of Camaquã. How is it that you are invoking it?
– Victor Stafusa
Camaquã’s webservice seems to be done on . net and he fired an exception
System.ArgumentNullExceptionbecause the stringswas null, which is analogous to ajava.lang.NullPointerExceptionin Java. What you put as this parameters?– Victor Stafusa
@VictorStafusa, Os parâmetros passados são:

>call.setSOAPActionURI("http://tempuri.org/INFSEGeracao/RecepcionarLoteRps");

>call.setTargetEndpointAddress("http://nfseteste.camaqua.rs.gov.br/NFSEWSTESTE/Services.svc?wsdl");

>call.setSOAPActionURI("http://tempuri.org/INFSEGeracao/RecepcionarLoteRps"); >call.setOperationName(new Qname("http://tempuri.org/", "Recepcionarloterps"));
– Mateus Folletto
I don’t know what would be causing this problem, since other cities make the shipment the same way and work normally. (Porto Alegre, Esteio, Novo Hamburgo, among others).
– Mateus Folletto
It may be a problem in their webservice. Having a
System.ArgumentNullExceptionno. net is the same as having ajava.lang.NullPointerExceptionin Java - or it’s laziness to treat the parametersnulls properly or is programming error.– Victor Stafusa
