Hi!!! I suppose this topic might not be mystery at all for all those who have been working with ZOPE for a while, but for me, as a beginner, it's really starting to look as a pain in the ***. The issue is namespaces. I've been dabbling across ZOPE documentation and help files, but somehow I never found an appropriate answer to my problem. Let me be more specific. Suppose I have all my files organized in the following directory tree: Work | |-- dmFiles | |-- sqlFiles | \-- pyFiles Consider that all my DTML Documents are located in the root directory (Work). DTML Methods, SQL Methods and Python Scritps are located respectively in the folders dmFiles, sqlFiles, pyFiles. So far so good... The problems start when I want to code one of the following situations: - call a Python Script (pyFiles folder) from a DTML Method (dmFiles folder); - call a SQL Method (sqlFiles folder) from a Python Script (pyFiles folder); What is correct code necessary to implement both this cases? Thanks in advance, Vitor Varalonga
