Chris, About the multipart data, it sounds like the Tomahawk Extensions filter is perhaps all you're missing. Take a look at this, http://myfaces.apache.org/tomahawk/extensionsFilter.html, and see where that leaves you. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [jug-discussion] Server now running
Hi William and Andrew, I'm having a bit of a problem navigating around http://myfaces.apache.org/tomahawk/ .? I downloaded the code from the "File Upload" link where a link to an example is given as "examples/fileupload.jsp", but this is very confusing, and I eventually found it at http://www.irian.at/myfacesexamples/fileupload.jsf.? As was said, the "enctype" has to be set to "multipart/form-data".? It also says that the MultiPart Filter has to be enabled in web.xml.? This is mentioned in "Core JavaServer Faces" where a listing is given, but so far I've been unable to find a link to it giving details of the xml file on the website you gave me. I've also had problems getting hold of the API, namely javax.faces.Input, org.apache.myfaces, and the API link on the website doesn't work, nor does "Impl", which presumably means implementation.? I got the code in the section on file upload in chapter 13 of "Core JavaServer Faces" to work on my laptop with Glassfish, but the listings are much more complicated than in the link you gave me.? The listings in the book imports org.apache.common.fileupload.* etc., which are included in jar files, as opposed to the link above where the bean imports org.apache.myfaces.custom.fileupload.?? I don't know how different this is. The problem I have with the book is that after the first few chapters it gives some very detailed examples, such as for file upload, which is good, but I'm lacking a tutorial on something very simple to get me started on this.? Taking the detailed example in chapter 13 and wading through it and extracting what I really need looks quite involved, so some help in getting started on this would be very much appreciated.

Re: [jug-discussion] Server now running
Many thanks for the correction. While working at Steward Observatory I was paid about the same as a 3rd grade primary school teacher, which I regarded as unacceptable,?but while I was under the restrictions of a?visa regime there was little I could do about it.? Once I got my "Green Card" and?had a big?paper in the Astrophysical Journal accepted for publication I felt free to strike out in a different direction. I guess that many?commercial JEE etc. programmers don't know much about scientific?and mathematical computing, and most scientists who do the latter (to a great extent in FORTRAN), don't know much about JEE programming.? Naturally I'm looking at possibilities that can take advantage of these combined skills, even though I'm still very new to JEE, and spend a lot of time learning and making mistakes.

Re: [jug-discussion] Server now running
Hi Andrew, Many thanks for your quick reply, and in particular for your information with the link.? It's really frustrating working in isolation here in France, without any person able to help me with my various questions, so I've had to use books and the Internet to get all my information.? Basically I started with Glassfish and server-side programming completely from scratch when I started here in October.? However, the positive side of my situation is that nobody here knows how I'm writing the code or understands what I'm doing, they only see the end result, so if I goof up, which I've done often, they don't see my silly mistakes, and I just say there is a bug which I'm trying to fix! I first worked on this project here a year ago, but they were unable to provide a computer to host the website, due to delays in getting the required funds, and I didn't have a laptop with Linux on it.? Moreover there was not much in the way of tools,?so when I first started I didn't know what server technology to use, so I developed all the client-side code in HTML, CSS, and JavaScript by hand using Notepad and a couple of browsers.? When I got Glassfish running in the fall, I already had my forms wired up using JavaScript and DOM, and rather than rewriting the client-side code from scratch, I modified the JavaScript to that I could concatenate the values from the various input fields on a page, then used the DOM to write to a separate JSF form I have at the bottom of a page.??No doubt there is a much better way of doing this, but I wanted to take advantage of what I had already coded and debugged. I have a bean that picks up the concatenated input, parses it, and sends the output to a directory which is periodically scanned by a Linux script, which then calls some FORTRAN code written by one of the people here.? Originally I wanted a bean to invoke C via the JNI, from which FORTRAN can be called, or invoke a Linux script from Java, and I found out how to do?both of these?and got some code to work.? However, the powers that be and their mentality on security meant neither of these methods were acceptable. On a completely different subject, I spent a couple of weeks last month learning some Flash, and put together my first attempt at http://csharp.com/mirrors.html , the idea coming from a T-shirt design at Steward Observatory. Yes, many thanks, I also certainly look forward to meeting you in person at the next JUG meeting after I get back to Tucson.
