I just got it working under BizTalk 2010, just a minor thing, the pipeline components dlls are supposed to be copied to /Pipeline Components, and don’t need to be gaced.

You can find my e-mail address on the about page of this blog.

public override bool Read()
{
Boolean result = wrappedReader.Read();
//Abir’s new code
if(wrappedReader.IsStartElement() && wrappedReader.LocalName == “FileName”)
{
//filename =
wrappedReader.ReadStartElement();

this.documentFilePath = @”C:\Projects\LEMA\POC\SchemaExtractor\Docs\” + wrappedReader.Value;

result = wrappedReader.Read();
wrappedReader.ReadEndElement();

}

if(wrappedReader.IsStartElement() && wrappedReader.LocalName == nodeNameOfEncodedFileContents)
{
if(wrappedReader.IsEmptyElement)
{
wrappedReader.Read();
}
else
{
Base64DecodeDocument(wrappedReader);
}
}

return result;
}

If you want you can send me your sample solution that depicts you problem. So I can look at it. If you do please make sure everything is included binding files, sample message, etc.
Thanks!

I used the sample as is with no orchestration in the middle. It worked fine. I then added an orchestration subscribing to a receive port. I get the following error:
The published message could not be routed because no subscribers were found. This error occurs if the subscribing orchestration or send port has not been enlisted, or if some of the message properties necessary for subscription evaluation have not been promoted.

Everything is enlisted and I have tight bound the Orchestration receive port.

Any clues, it seems to me like all the relevant promoted properties are not coming through.

Can you mail me your pipeline code along with a test message so I can have a look. It has been some time since I wrote this so I have to dig into it again.

Thanks!

Thanks very much for this, it is very interesting and educational. I learned a lot. I modified the send pipeline a little, so that it checks for certain elements and then uses the filename in the element and replaces the element contents with the base64 encoded file. It works very well.

However, now I want to do the reverse on the receiving side. My problem is that my messages have many elements containing base64 encoded data. I need to be able to check for certain elements that contain the base64 encoded data and at that point, decode it and save it to file, and replace the base64 data with the filename of the file I have just created from it. I almost have it working. A series of files are extracted and stored. The problem I need to solve is that the output message has the elements that used to contain the base64 data absent. I think this is because I have called ReadElementContentsAsBase64. It seems to consume both the start and end elements. I wonder if I need to combine the subclassed XmlReader with the subclassed XmlTranslatorStream in the same component perhaps?

I wondered if you had any ideas?

Thanks again for the excellent article.

As Far I understood the pipline properties I have stated them as below

Receive Pipline Side:
ContextKeyForDocumentFilePath: StoredFile (What does this property mean)
ContextNameForDocumentFilePath (This can be any random namespace or it shoul be namespace as per my incomming message)
DocumentFilePath:(Path where I want the encoded content to be moved to)
NodeNameOfEncodedFileContent: (Node which I want to strip off)

Send Pipline Side:
ElementToCreateName: (Node name to create which holds my endoded data)
ElementToCreateNamespace: (What Should go here)
ElementToCreatePrefix: (What Should go here)
FilePathPropertyName: (This can be any random namespace or it shoul be namespace as per my incomming message)
FilePathPropertyNamespace Element after which I put in my encoded data)

Kindly correct me if I am wrong on this understanding.

Thanks and Regards,
Nilesh.

In the properties of the pipeline (component) you need to fill in the path where the base64 encoded part (in this case the .pdf) will be stored. It probably does not have a value set now.

Glad that u replied.
Yes I used the sample as downloaded. The MSI file worked for me but when I Build and deployed the sample solution it threw the above error. My guess is that some environment variable might be missing missing. Are u setting any environment variable in the MSI file.
Also can I get your emailid so that I can mail u my solution. The only changed I made were, setting the pipeline properties.

Thanks and Regards,
Nilesh.

I am not able to unserstand where the parameter gets passed.

Thanks for your comment.

Are you using the sample as downloaded? Or did you make any modifications? If so please .zip and mail me your modified sample so I can take a look (also include the binding file).

Thanks and Regards,

The following items could not be matched up to hosts due to name and/or trust level mismatches:
Item: ‘FILE’ Host: ‘BizTalkSendHost’ Trust level: ‘Untrusted’
You must do one of the following:
1) Create hosts with these names and trust levels and try again
2) Re-export the MSI without the binding files and have a post import script apply a suitable binding file. (Microsoft.BizTalk.Deployment)

Here i created BizTalkSendHost with untrusted but still no success. so i started to create manually the receive and send port.

Now i am having the below issue. Could you help me if time permits for you. I verified the path and also XmlStoreAndRemove.btp which is
C:\Sample.Pipelines\Temp\Document_%Guid%.pdf

There was a failure executing the receive pipeline: “Sample.Pipelines.XmlStoreAndRemove, Sample.Pipelines, Version=1.0.0.0, Culture=neutral, PublicKeyToken=6e8722a4213dc18d” Source: “Pipeline ” Receive Port: “ReceivePort_Base64″ URI: “C:\Sample.Pipelines\In\*.xml” Reason: Path cannot be null.

Thanks,

I tried to download and unzip the .zip file myself. Seems ok from this side. I’ll mail you the .zip file anyway.
