jasperserver multipart response

[rossi-jeff]

I am trying to convert some SOAP::RPC::DRIVER code I was using to fetch pdf documents from jasperserver. This probably isn't really an issue I just can't seem to find how to do it in the documentation.

My xml request

portion of backtrace from error

Are there some options to invoke or a method of response that will make this work?

[troelskn]

What's the error message? It seems to be something in the http-parser.

[troelskn]

Oh .. and if you switch to a different http-driver, does the problem go away?

Here's the full backtrace caught by a rescue clause in my controller

And here's the method from my handsoap model

def run_report(report,format,parameters)
soap_action = 'runReport'
xml = ''
doc = Builder::XmlMarkup.new(:target => xml)
doc.request(:operationName => 'runReport', :locale => 'en') do
|request|
request.argument(format, :name => 'RUN_OUTPUT_FORMAT')
request.resourceDescriptor(:name => '', :wsType => '',
:uriString => report, :isNew => 'false') do |resource|
resource.label('null')
if parameters.size > 0
parameters.each do |k,v|
if v.is_a?(Array)
v.each do |v2|
resource.parameter(:name => k, :isListItem => true) do |p|
p.cdata!(v2)
end
end
else
resource.parameter(:name => k) do |p|
p.cdata!(v)
end
end
end
end
end
end
response = invoke('runReport', soap_action) do |message|

message.set_attr("env:encodingStyle","http://schemas.xmlsoap.org/soap/encoding/")
message.add('requestXmlString',xml) do |request|
request.set_attr("xsi:type","xsd:string")
end
end
return response.http_response.parts
end

I'm hoping it's just a simple error on my part.

Thank You

I'm not sure how to do that.

Put this in your global config to switch to the Net::HTTP driver

Handsoap.http_driver = :net_http

You can see a full list of supported drivers here

`parse_multipart'

This is the culprit. It appears that the response, which is a multipart, is malformed. I suspect that this is a problem with the http client driver (curb), but it could also be the server sending garbage. If it doesn't work after switching http client driver, can you try to dump the tcp stream and attach it here? You can use tcpdump or Wireshark for capturing the stream.

The server is jasper server and I have gotten pdfs with
SOAP::RPC::DRIVER, can I change the http driver for just this class or
possible just the method to get pdfs instead of globally? I have 2 other
classes that are working properly using handsoap w/ curb.

Watch out - that Authorization header is giving away your user/pass in plaintext (it's just base64 encoded). Might want to change that after posting it here. Or edit the post quickly.

[troelskn]

The server is jasper server and I have gotten pdfs with
SOAP::RPC::DRIVER, can I change the http driver for just this class or
possible just the method to get pdfs instead of globally? I have 2 other
classes that are working properly using handsoap w/ curb.

You can override http_driver_instance in your service class

[troelskn]

This is a wild guess, but the other service calls that works - would they happen to be smaller in size? I think the parser may be stumped by the content being in chunked mode. If that is the case, it would require some addition to the http parser library. I would expect this to not be a problem with other drivers than curb, as they will probably abstract the chunked part away. Did you try with another http driver?

I added

http_driver_instance = :net_http

just after the endpoint line in my service class

Isn't the chunked part what I want?

overwriting driver actually took

def http_driver_instance
Handsoap::Http.drivers[:net_http].new
end

But still no joy

Isn't the chunked part what I want?

No, multipart and chunked transfer are two separate matters. Chunked refers to the ability to send a large http response in multiple "chunks", rather than as one stream. So it's a transfer encoding (Sort of like gzip or other transfer-level encoding). Multipart is something higher level (Eg. is parsed later in the process).

But this is just a hunch of mine - It might be a red herring.

I'll suggest that you try to edit /usr/lib/ruby/gems/1.8/gems/handsoap-1.1.8/lib/handsoap/http/drivers/abstract_driver.rb and dump the contents of status to see if that makes us any the wiser. Something is clearly going wrong with the parsing around that line.
