Re: [base] downloading files
yeah, there are too many changes to integrate into 2.1.1 the 2.1.2pre branch does not have the new classes i tried to upgrade to the trunk, but it blows in too many places.. so i guess i'll just wait for the classes to be released.. thanks again for all the help, -keith Nicklas Nordborg wrote: Keith Ching wrote: Hi, I am getting a peculiar stack trace upon trying to define the plugin. do you think it could be caused by using Base2.2 classes in a Base2.1.1 codebase? i tried to include the revised classes in the plugin JAR.. but i suppose this probably doesn't work.. i had to include Base2.2 versions of net.sf.basedb.core.Path net.sf.basedb.util.FileExportOutputStream net.sf.basedb.core.plugin.AbstractExporterPlugin net.sf.basedb.core.plugin.ExportOutputStream net.sf.basedb.core.plugin.ImmediateDownloadExporter do you think it would be safe to just replace these files in 2.1.1 and rebuild it? It is nothing that we recommend and we are not going to help you with any problems resulting from mixing two BASE versions. The immediate download functionality also depends on changes in JSP pages and other java classes. If you check ticket #189 (http://base.thep.lu.se/ticket/189) you can see all changes related to this issue.

[base] downloading files
I have a List of File objects. what is the best way to zip them all together and download it? Is there a way to get the Httpresponse object from inside a plugin? If the files are really large, would it better to write the outputstream to the local filesystem and have the user find and download the archive from inside their home dir? is there a nice File.Action.addZip ? thanks, -keith -- Keith Ching, Ph.D. Bioinformatics, Laboratory of Gene Regulation Ludwig Institute for Cancer Research 9500 Gilman Drive, #0653 CMM East, Room 3020 La Jolla, CA 92093-0653 [EMAIL PROTECTED] 858-822-5767 - Take Surveys.

Re: [base] downloading files
Keith Ching wrote: I have a List of File objects. what is the best way to zip them all together and download it? I assume that you want to this with a plugin. I think the best way is to create a new File (net.sf.basedb.core.File) object and then use java.util.zip.ZipOutputStream for writing to the new file. Is there a way to get the Httpresponse object from inside a plugin? Not really, since plugins are executed in the background or maybe even on a different server. In the the upcoming 2.2 release we have added the interface net.sf.basedb.core.plugin.ImmediateDownloadExporter that more or less makes it possible for a plugin to send the output to the HTTP response. Look at the source code some of the existing export plugins (for example HelpExporter) to see how to use it. If the files are really large, would it better to write the outputstream to the local filesystem and have the user find and download the archive from inside their home dir? Maybe. I don't think a zip stream needs much memory or uses very much CPU. The main problem is probably slow network connections. If you use the net.sf.basedb.core.plugin.AbstractExportPlugin as a base class it can help you with supporting both immediate download and saving to the file system. is there a nice File.Action.addZip ? No. /Nicklas - Take Surveys. Earn Cash.
