How to transfer files using ibm web sphere message queue in .net? - asp.net

I am using IBM WebSphere Message Queue for transferring my messages in .NET. Now I want to send some files using the message queue, is it is possible to send all file formats? And how can I send them using .NET?

There are two ways I think.
1) Use WebSphere MQ Managed File Transfer (WMQMFT) product to transfer files. WMQMFT is a product built on top of WMQ. More details here
2) Write your own .NET application that
a) At the sender end, reads the file data
b) Attach the file data as message body to one or more messages.
c) Send message(s) to a queue.
d) At the receiver end, receive message(s) from the queue.
e) Assemble messages and write to a file.

WMQ does not care what the message data is. Therefore, read the file then send it as a message but remember that the "default" maximum message size is 4MB. Your MQAdmin can change the maximum message size to a maximum of 100MB.
If you need to transfer files greater than 100MB than you will need to use WMQ MFT or the open source project: Universal File Mover. http://www.capitalware.biz/ufm_overview.html

BizTalk: Mapping not executed when using unzip-component

I am building an integration that should fetch a zip-file from SFTP and save it as XML on disk. I have got everything working except the unzip-part...
The integration looks like this.
Receive location polls the SFTP, and in the receive port "Inbound maps" I have provided a mapping schema (converting the txt-file in the zip file to XML).
Receive location: polls the SFTP, custom receive pipeline.
Custom pipeline: In Disassemble first the unzip-component from BizTalk Utility pack ( BizTalk Server 2020 – 20 days, 20 posts: Unzip File Pipeline Component for BizTalk Server 2020) and then the flat file disassembler. The document-schema here matches the source-schema in the mapping.
Send port: Save file on disk.
The problem is that when I run the integration, the file is picked up from the SFTP and the file is indeed unzipped but the send port saves the content from the original file to the send-location. It is as if the mapping is never executed.
But if I remove the unzip-component in the custom pipeline and manually unzip the file and upload the content (.txt-file) to the SFTP everything works fine.
As per Sandro Pereira's instruction no configuration is needed, so I don't really understand why it is not working.
Receive Pipelines - Disassemble stage (Microsoft.com)
If this stage contains more than one component, only the first component that recognizes the message format is run. If none of the components within the stage recognize the message format, the message processing fails.
So you can't have both in the disassemble stage of the pipeline and have them both execute. Move the Unzip to the Decode stage of the pipeline.

Can I use a single pipeline for both a file receive location and an email receive location?

I have a pipeline that is working for a file receive location. This pipeline accepts a csv file and maps it to an XML.
I'm now trying to setup a new email receive location using the same port, pipeline and pipeline settings.
Shouldn't biztalk ignore everything but the attachment if I set the body part index equal to 2? And then it should place the attachment in the pipeline just like with the file location, then the pipeline would output an XML file.
Error:
Microsoft.XLANGs.Core.PersistenceException: Exception occurred when persisting state to the database. ---> Microsoft.BizTalk.XLANGs.BTXEngine.PersistenceItemException: A batch item failed persistence Item-ID 72fbeba9-6bfe-48e0-a0e6-ca5bbd191aa1 OperationType MAIO_CommitBatch Status -1061151998 ErrorInfo The published message could not be routed because no subscribers were found. . ---> Microsoft.BizTalk.XLANGs.BTXEngine.PublishMessageException: Failed to publish (send) a message in the batch. This is usually because there is no one expecting to receive this message. The error was The published message could not be routed because no subscribers were found. with status -1061151998

PipelineConfigurations:
I tried stopping the orchestration and the send port and test both locations.
Testing the email location I got the same error with an email with a .csv attachment.
Testing the file location the data didn't reach the database, but the csv was processed because I could see it in the information logs.
This leads me to the conclusion that the problem is related with the mime decoding and whatever my pipeline is outputing from the email body parts.
Also after researching for a while all solutions seem to point to the necessity of having a pipeline exclusively for email since I need to say which part of the multibody part to decode. I was hoping there was a solution that would allow me to reuse the pipeline I use for the file location.
As #Dijkgraaf mentioned:
It is not failing in the pipeline. It is failing due to there being no Orchestration or Send Port that is expecting the message the Receive Port has published to message box.
That means that the receive worked, that the message has passed the pipeline, and is published in the Messagebox, but there is no matching subscription.
Check for routing failures in the BizTalk management console to find out why. It may be that the message type is not waht you expected, or that one more published properties are not set correctly.
See the suspended message and check which body part is the CSV file. Your config says its it should be the 3rd message BodyPart = 2.

Executing BizTalk Flat file disassembler pipeline inside orchestration

I am not new to BizTalk however this situation is somewhat new. I have below situation in an BizTalk Orchestration,
I get path of flat file from some other source.
I want to load this file in orchestration and disassemble it by executing pipeline.
I searched a lot but almost every one talks about feeding a XML document in pipeline inside orchestration.
I got below links too but I couldn't get the working solution so far,
Calling FlatFile pipeline inside orchestration
4 Different ways to process an XLANGMessage
When I implemented solution given at above links, I get error "No Disassemble stage components can recognize the data."
I also don't want to create dynamic receive locations because of performance constrains.
Below is my code so far,
Load file content in a stream
Create a CustomBTXMessage instance as suggested in link two.
Load stream as below
customBTXMessage = new CustomBTXMessage("MyMessageName",
Service.RootService.XlangStore.OwningContext);
customBTXMessage.AddPart(string.Empty, "Body");
customBTXMessage[0].LoadFrom(ms);
return customBTXMessage.GetMessageWrapperForUserCode();
I think this situation is not something new in BizTalk world. Any one who has done this must be able to help me quickly.
Here's what I would do...or at least try first.
Create a Receive Port and Receive Location for each Flat File type you get.
Get the list of files.
In the Orchestration, Move the file to the appropriate Receive Location.
Flat File Disassembler the file in Port Pipeline like normal.
Receive the File into the Orchestration with an Ordered Delivery Port bound to the Receive Port from Step 1.
Loop on Receiving the files, checking for BTS.LastInterchagneMessage.
When True, Exit that Loop and go back to step 3.

Send notifcation if expected message did not arrive in BizTalk

I have a BizTalk receive port monitoring an FTP location. I expect a file to arrive at least once per day in that location and for BizTalk to pick it up and kick off an orchestration. This part is working fine.
However, sometimes the sender fails to send a message during a day, in which case I want an email to sent to notify the users that something is amiss.
I could solve this outside of BizTalk, by creating a daily job that looks in our database for processed files and makes sure there is at least one in any given day. However, I'd prefer to solve this "in line" with the BizTalk solution that is already in place, and not deploy a separate, unrelated job which will increase maintenance headaches.
Is there any functionality in BizTalk that would allow me to send a notification if a receive port doesn't receive something in a given timeframe?
Short answer: Not really.
The logic you want to implement would require a customised version of the FTP Adapter. Depends on how comfortable you are rolling up your sleeves and getting into the Adapter SDK.
If you wanted to keep your solution "Purely BizTalk", you could set up a secondary Orchestration using a SQL Receive Location tied to a stored procedure. This stored procedure executes regularly and looks for records in your "Processed File" table received in the past (business) day. If none are found, it fabricates a record and returns it via the SQL Receive Location. This would be your trigger to send the email notification.
One solution, not elegant though, is to have a secondary FILE receive location, with a schedule window, outside your cutoff time.
Failure scenario:
In this FILE receive location, you have an intelligent/dummy message conforming to the same schema as FTP receive. The intelligent part is to have one of the fields in the message telling us when was the last time we received the file from FTP. The rest of the content is dummy.
Within your orchestration, you check where you received your file from. If its the secondary receive location (using the context property BTS.ReceiveLocationName), you check the date field of this dummy/intelligent message and if it is in past 24 hours ( or similar logic) send an email notifying you did not receive the file from the upstream FTP process and also save a copy of the dummy message (received) back to the secondary FILE receive location unchanged.
Success Scenario:
Apart from normal processing, you save a copy of the dummy/intelligent message to the secondary FILE receive location, with the datetime field reflecting when you processed the file you received from FTP receive location.
Initialising:
You start with a dummy/intelligent message in the secondary FILE receive location with the datetime field value well in the past ( assuming we never received the file from FTP) or with yesterday's date ( assuming we received a file successfully from FTP the day before.)
Overview:
Your orchestration has two trigger points.
When you receive a file via FTP
A scheduled FILE receive location, triggered after the cut-off time.

How do I send a message from a web site to my local machine?

I want to send a string from a website to a local machine.
My local machine is connected into a network through a router.
Thanks You

Well, that largely depends on what the receiving computer needs to do with that string.
If you only need to notify the user of this, I would suggest the easier way is to go with the net send command.
Since you are wking in ASP.net, you can use the Process and ProcessStartInfo class to launch a command like
net send YourPC "String to send"
If you need to do something more sophisticated with the string message, you could for example print it in some sort of log file and then read it from the destination machine.
If you can give more information on your needs, we'll be probably able to help you better.

I suggest you poll the webapp for messages.
For instance, let the webapp have an URL that simply returns the timestamp of the most recent message, at http://thesite.com/messages/MostRecentTimetamp.aspx
The page should return the timestamp only, in an format you can parse, for instance:
2009-08-29 14:00:00
Then, on another URL, http://thesite.com/messages/FromLastHour.aspx display the list of messages for the last N hours (or other suitable time period). This page could return one message per line, with the message timestamp at the start of the line.
For instance:
2009-08-29 13:58:20 A message
2009-08-29 13:59:30 Here's a message
2009-08-29 14:00:00 Another message
On your local machine, create a program that as often as needed reads and parses http://thesite.com/messages/MostRecentTimetamp.aspx. If the program detects that the timestamp has changed, read http://thesite.com/messages/FromLastHour.aspx and process the new messages.
Adjust the timing according to your needs.
Or even better, have an URL: http://thesite.com/messages/MoreRecentThan.aspx?timestamp=2009-08-29 13:50:00.
That returns messages that are newer than the timestamp passed in. The program on your local machine should then pass the timestamp of the most recent message it has handled.
Of course, your web site has to keep track of outgoing messages in some sort of queue. You could use a database table for this. The web app can delete old messages from this table periodically.
If you want to get fancy, you could implement this as a SOAP web service. Or you could let the URLs return the data formatted as JSON.
