JSP to download OpenCms resources as a ZIP
Thursday, June 25th, 2009What often bugged me is that I can upload a set of files into OpenCms as a ZIP file but can not download a tree of files as such (without the use of the database export feature). I had hacked together this little JSP some time ago. It allows you to dynamically download a set of OpenCms resources as a ZIP file.
The JSP has no interface since I mainly use it for development. Simply create a JSP somewhere in the OpenCms VFS and then open the file via the browser. E.g.:
“http://workplace.com/system/createzip?source=/system/modules/foo&filename=foo-module.zip”
The source parameter specifies which directory to zip up and the filename parameter which filename to use for the generated file. You can only zip up resources with a total size of 10 megabytes. This is mainly to prevent OutOfMemory errors to happen. You can easily increase the size by altering the variable maxSourceSize to any value you need.
If you find any bugs or want to give feedback simply leave a comment or send me an email.
