calling a method with xsd__base64Binary

[Jamie <ja...@mweb.co.za>]

Hi

I am using the Axis C++ API to send compressed emails from a C++ client 
to a server implemented in Java.

In my client code (see below), I have an exposed function called 
storeMessage, that has a xsd__base64Binary parameter. When I send the 
email without compression (i.e. plaintext), the data is passed 
correctly. However, when I compress the data using zlib, I get a wierd 
message "xarchiveInternalReturn e" (each letter seperated by null 
characters) coming through as a parameter. See source below.


                        CA2GZIP gzip((char*)pszBuffer,ulFileSize); // 
wrapper library for zlib services.. pszBuffer contains plaintext email
                        char endpoint[256];
                        sprintf (endpoint, 
"http://127.0.0.1:8080/testservice/services/TestService");
                        TestService webservice(endpoint);
                        xsd__base64Binary bb;
                        bb.__ptr = (xsd__unsignedByte*)gzip.pgzip; // 
contains compressed data
                        bb.__size = gzip.Length;
                        FILE *aout=fopen("c:\\test.gz","wb"); // just 
for testing to see that the message is valid for debugging purposes
                        size_t count1=fwrite(bb.__ptr,1,bb.__size,aout);
                        fclose(aout);
                        webservice.storeMessage(bb);
       
Am I missing something here? I assume the AXIS will take care of the 
base64 conversion before sending the message?

I have also noticed that Axis C++ generates a nasty access fault when an 
exception is thrown from the client. It tries to delete a stray pointer. 
Has anyone experienced problems with exceptions?

Thanks in advance for your help.

web service exception causes crash - possible bug in WSDL2Ws?

[Jamie <ja...@mweb.co.za>]

Hi everyone,

I am using the latest nightly build of Axis C++. My client application 
crashes when an exception is thrown from the server via Axis web 
services. The generated code (see below), attempts to delete memory 
pointed to by detail (fault point is marked below). The contents of 
detail at this point is"<hostname>jamie</hostname>". Any ideas on how to 
fix this? From time to time, my server application throws exceptions.. 
in which case i'd like the client app to behave responsibly.

Thanks in advance for your help.

Is this a bug in the code generated by WSDL2Ws?
