4.3.1 Setting up an export directory

  • Set up a file directory for storing the SEPA files. The directory should be located on the server on which Nuclos is installed.
  • Read and write access to these directories must be ensured for the Nuclos service.

4.3.2 Integrating the server extensions

  1. Set up the directories "extensions" and "extensions/server" in the Nuclos installation path.
  2. Place the JAR file extensions/server/org.nuclet.sepa.jaxb-2.3.0.jar from the ZIP file under "extensions/server".
  3. Copy this JAR file into the Nuclos installation path to "webapp/WEB-INF/lib".

The JAR from step 4.3.2 contains Java classes for generating the SEPA XML files. The JAR consists of two Java packages, one each for direct debits and credit transfers.

These packages also define the SEPA namespaces:

  • "urn:iso:std:iso:20022:tech:xsd:pain.008.001.02" for direct debits in the package org.nuclet.sepa.jaxb.sdd and
  • "urn:iso:std:iso:20022:tech:xsd:pain.001.001.03" for credit transfers in the package org.nuclet.sepa.jaxb.sct.
