PayloadZipBean + MessageTransformBean

[#1]

Hi all,

This is my first post on SCN. I hope to be a positive resource to this community. 🙂 I wanted to ask a question I have been riddled with for some time. We had the requirement to use a sender file adapter for zipped plain text files (sort of CSV file).

Issues I encountered:

1. GZip is not really supported by the PayloadZipBean: I assume there is no way around this (Question 1), so we decided to switch to normal Zip files
2. Using File Content Conversion:
   • Apparently this is not possible, as it tries to convert the inbound zip file into an XML: replaced this by the MessageTransformBean.
   • So at this time, the modules set up are: PayloadZipBean with mode set to unzip, afterwards, the MessageTransformBean with all the parameters set up correctly. This was working fine, as long as the input did not contain any special characters. So on to the next issue.
3. The plain text files are in codepage ISO-8859-1. I have tried TextCodepageConversionBean with the conversion.charset set to utf-8. I have also tried to use the XMLAnonymizerBean (and changing the charset of the XML to ISO, but no result) before the MessageTransformBean. However, this still results in special characters being replaced by ï?n or question marks. I assume this is because the TextCodepageConversionBean only works on payloads of type plain/text, while the result of the PayloadZipBean is "application/octet-stream". Is there any way to do this properly? (Question 2)
4. My workaround is quite simple. I use the PayloadZipBean module in a first sender adapter. Drop this file with a file receiver adapter and then use a second file sender adapter with normal FCC with the Encoding set to ISO-8859-1. This works fine - special characters are read correctly. However, I would prefer doing it all in one sender adapter.

If anyone has any answer to my questions or is maybe doing something similar and has questions, please feel free to answer my post! Also thanks to Stefan Grube for his great post working-with-the-payloadzipbean-module-of-the-xi-adapter-framework.

Hi Aerv,

After reading your post i learned many things, i would prefer 4th point solution to achieve your requirement. Because doing in one scenario may be big risky

But solution is use OS Command script to zip your file and call OS command in File channel with option beofore message processing then use otehr module(code page conversion).

Hi Raj,

Thank you for your feedback. I know that using an OS command to unzip (I'm not zipping the file) would also work. But would prefer to do it all in the adapter.
