Ermanno,

Please add the attached USR0029 member to file QWSDL2RPG and then run A_INSTALL again.

By the way there was no need for installing the beta if you actually decided to fixMarshaller_toBase64Binary(). What I said was either fix WSDL2R98 _or_ install the beta.


Nevertheless, sorry for the missing USR0029 member.

Thomas.

I corrected the procedure Marshaller_toBase64Binary as indicated,
I downloaded the beta and I've redone the installation

In creating the module WSDL2R01 I get the error: USR0029 State QWSDL2RPG
file not found, the installation terminates.

What can I do?

Ermanno,

Based on your input I was able to fix the bug in WSDL2RPG. The problem you
encountered with your web
service actually was a problem of the Base64 UnMarshaller. By mistake I
defined a field as 2I0
(integer) instead of 2U0 (unsigned integer). Because of that mistake the
maximum data size was reduced
to 32k instead of 64k.

I did not change anything in 'ws_cab', because I actually did not use it to
debug the problem. Since
the mistake was in service program WSDL2RPGRT, there is a good chance that
you do not need to change
something in 'ws_cab'. I used your debug data to create my own test web
service and based on that web
service I debugged the problem. Guess what, it is a nice barcode that you
will get.

There are two options to fix the problem:

1) Change the following lines in WSDL2R98 and reinstall WSDL2RPG:

    Procedures: Marshaller_toBase64Binary
                UnMarshaller_toBase64Binary

    Before: D outLength               1      2I 0
    After:  D outLength               1      2U 0

2) Download the latest beta from here:

    http://www.tools400.de/beta/wsdl2rpg_v1.10_20091206_1932.zip

In case you do not know how to save the decoded file data to a stream file,
here is the code I used do
do that:

    /COPY QIFS,PIFS                              IFS IO-Procedures
    ...

    // Now let's call the web service.
    getBase64EncodedJpegFileResponse =
       Base64File_getBase64EncodedJpegFile(
           requestMessage:
           errText);

    // If the Web service finished successfully ...
    if (not Base64File_isError());
       // ... write image data to IFS file.
       path = '/home/raddatz/wsdl2rpg/' +
               getBase64EncodedJpegFileResponse.fileName;
       hFile = f_openIfsFile(path
                             : O_WRONLY + O_SHARE_RDONLY +
                               O_CREAT + O_EXCL
                             : *: *: *);
       if (hFile = RC_ERROR);
          sndMsg('Failed to open file: ' + path);
       else;
          bytes = f_writeIfsFile(hFile
                              : %addr(getBase64EncodedJpegFileResponse...
                                     .fileData) + 2
                              : %len(getBase64EncodedJpegFileResponse...
                                     .fileData));
          f_closeIfsFile(hFile);
       endif;
    else;

In order to use the IFS procedures you have to bind to service program IFS.

Last but not least do not forget to increase the size of
'retriveDDTObjectReturn':

      D impl_retriveDDTObjectResponse_t...
      D                 DS                  based(pDummy)
      D                                     qualified
      D  retriveDDTObjectReturn...
      D                              128A   varying

For my test web service I set it to what is shown below:

      D tns_getBase64EncodedJpegFileResponse_t...
      D                 DS                  based(pDummy)
      D                                     qualified
      D  fileData                  64449A   varying
      D  fileName                    128A   varying


Regards,

Thomas.

I will be very grateful if you can fix the problem.

Ermanno,

I agree that it seems as if the web service returns the binary image data

as

element data of element
<retriveDDTObjectReturn>. Most like this is the reason why you receive the
"receiver is too small"
error message.

Without the wsdl file all I can do is just guessing that your stub module
should have a procedure
ending with "retriveDDTObjectReturnEnd". That should be the procedure

which

receives the data of
element <retriveDDTObjectReturn>. Feel free to start the debugger and add

breakpoint to that
procedure. When "depth" is 2, "value" should contain the image data and
"name" should be set to
"retriveDDTObjectReturn". If that is true, it is up to you to modify the
stub module to put the image
data to a place of your choice.

The problem is the 64k barrier of RPG. Of course I could use pointers and
dynamic memory allocation to
manage larger response data but I am fairly sure that most of the RPG
programmers would not be happy
with that. The other option is to wait for V6R1 which allows fields up to
16MB.

Just because I am curious, what is the schema type of
"retriveDDTObjectReturn"?

Last but not least, if you cannot fix the problem on your own, feel free

to

send the generated stub
module to me. At the moment I do have much time left for playing around

but

perhaps I can fix it
quickly. Having said that: I did not promise you anything.

Regards,

Thomas

Thomas, sorry for the delayed response, we'll send debugging where I

understand that the web service called me back the string of the image

that

I think exceeds 64K.
If this is the reason how can we fix this?

Ermanno,

May you please turn the debug log on and pass the debug log along with

the

wsdl file to me? Please ensure that the debug log does not contain any
ctritical data such as user name and password.

Please do not post the log and the wsdl file to the mailing list but send
it directly to my tools400.de e-mail address.

Thomas.

Thomas, to better clarify my application it m makes a request to the web
service by passing the host name of an image and must receive the stream

of

the image to be displayed on the browser
While I am on first use of this tool, but I expect that the function
retriveDDTObjectResponse, contains this stream of return and that I can

open

the image as if it had any link .. here is where does the limit I

mentioned

that I could be 64K.
This is the procedure or must return an attachment, stored on IFS and

then

display it
someone can clarify this fact,
thanks for your availability,
Ermanno.

i Thomas,I changed the value localhost with 192.168 .... exposed the

problem

was due to a firewall that blocks traffic.

Now that I can reach the host comes back to me the following error:

The value of the receiver is too small to hold the result.

16: recvchunk: saveproc: Not all data was written

-1009: The value of the receiver is too small to contain the result

Got an idea on what may be caused?

the web service I should return the stream of an image;

There are size limitations?

Ermanno.
