RE: Still having problems with File upload (multipart-formdata)
Hi Patrick, okay attched is my class it offers only two methods. soon more... perhaps ;-) one stores a form-file to a place, defined in a PROPERTIES-File under uploadPath-KEY the other stores the file to a place which is the second-parameter ;-) both methods are static. The class has only a private Construktor, so it is final... :-) With String placeString = getServlet().getServletContext().getRealPath(/); you get the Path of your Struts-App like: C:\Tomcat\webapps\myStrutsApp so you could use the second like: UploadFile.saveFile(myFormFile, placeString); your file is then in root. hope this is what you needed. greetings matthias -Original Message- From: Patrick Scheuerer [mailto:[EMAIL PROTECTED] Sent: Tuesday, December 30, 2003 5:15 PM To: Struts Users Mailing List Subject: Re: Still having problems with File upload (multipart-formdata) Matthias Wessendorf wrote: Hi Patrick, you want to get the path of /myapp like C:\Tomcat\webapps\myapp or?

Thank you very much for your help! I would also offer a couple of cautions about this approach: * You are not guaranteed that a particular servlet container even *has* a concept of a directory in which the web app is deployed -- for example, even Tomcat can execute a webapp directly from the WAR file. When you do that, getRealPath() returns null instead of a pathname, and your calculations above will trigger a NullPointerException. * Even when you know that your apps are being deployed in unpacked directories, uploading things directly into that directory means you have to be careful about redeployment when you update the app -- the normal behavior of delete the old directory and replace it with the new app wipes out any uploaded files. I would recommend defining a directory somewhere in your server to hold the uploaded files for a webapp, and then pass the pathname of this directory to your app as a context init parameter or something like that. This approach deals with both of the problems identified above. Patrick Craig - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Still having problems with File upload (multipart-formdata)
I'm refactoring (so to speak) my currently working form, which accepts an image to be uploaded, to use a DynaValidator(Action?)Form and I'm again running into an exception being thrown: java.lang.NoClassDefFoundError: org/apache/commons/fileupload/FileUploadBase$SizeLimitExceededException What's going on here?! Also, to get more mileage out of this post, what exactly is the difference between a DynaValidatorForm and a DynaValidatorActionForm?! -- Brice D.

I believe the only difference is in the key passed to the Validator. The former uses the value of the 'name' attribute from struts-config.xml, while the latter uses the value of the 'path' attribute.
