Java code downoads all emails attachments.txt (3.5 KB)

Hi Mohammad,

You should take your java code and create out of it 2 services:

  • isBlank
  • downloadAttachments (this is the main method of your current class)

Afterward, you can use the downloadAttachments service from wherever you want (Flow or Java).

If this works, you can do some refactoring work.
For example, you might find another standard service that verifies if a string is blank, so you do not have to do it again.

Hope it helps,
Vlad Turian


there are Built-In-Services for the file handling available (when using a recent version of wM 9.x or wM 10.x).
