PayloadZipBean - variable filename inside the archive

[Former Member]

Hi,

I'm using the Adapter-Specific Message Properties in a sender fileadapter to determine the incoming filename, which has variable components (i.e. date and time). After changing the prefix and suffix in a Message-Mapping the new name is applied in a receiver fileadapter. The new name is now part of the payload in the tag <Filename>. The receiver fileadapter contains the PayloadZipBean to compress the output file, everything works fine.

Now I want the file inside my compressed archive always to have the same name as my archive has. In Stefan Grube's blog about the PayloadZipBean I only found the possibility to choose a fix name by using the MessageTransformBean (name="file.txt").

Example:

1. variable input filename: IN_RNK_20080227_1006.txt

2. filename after Message-Mapping: OUT_RNK_20080227_1006.gz

3. archive filename after receiver adapter: OUT_RNK_20080227_1006.gz

filename inside the archive: MainDocument (this is the default (payload-name))

I would like to name the file inside the archive OUT_RNK_20080227_1006, too.

Question 1: Is there any possibility to read out the mapped <Filename>-tag from the payload to use it for the element inside my archive (File Name Scheme and Variable Substitution don't work when using Adapter-Specific Message Properties).

Question 2: Is there a way to modify the name of the payload so that I can change "MainDocument" to "OUT_RNK_20080227_1006"?

I'm on XI 3.0 - SP19.

Many thanks,

Ralph

This is not possible with standard functionality.

You have to write an adapter module that stores the file name for example in the content type.

Hi Stefan,

One more guy to say thanks for your blog [Zip or Unzip your Payload with the new PayloadZipBean |https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/5899] [original link is broken] [original link is broken] [original link is broken];

I am following this thread now as we have similar issue. Is there some example code that we can refer to to write such adapter module. We have to get the filename that is available in the dynamic configuration and put it in the content type as we are having difficulty in setting the filename in the ZIP archive as per the sender filename. The PayloadZipBean only allows certain fields to be used for filenames.

However we are successful in naming the ZIP file name correctly as per sender file name at the receiver.

For this we are using the AF_Modules/DynamicConfigurationBean to write the File Name from the dynamic configuration to message.interface and then using Variable Substitution to use this key to format the receiver filename.

This works fine for the ZIP archive name and want to make sure the name of the in the archive also is correct and not something hardcoded.

In this thread there is a module for reading the content type and setting the dynamic configuration:

It should be not be so difficult to derive the reverse way.

Thanks for this info Stefan.

The code of the EJB module we had to write to get the filename from the Dynamic Configuration (ASMA) and then set the content type of the message is given below.
