Executing KSH shell scr thru web-page using JSP or servlets - req. assistan

Hi - I have a shell scr which I regularly use thru UNIX terminal. It takes parameters like -stgdir=xxx, -abc, -def, etc. etc. and then kicks off processing whatever it's supposed to do. It does not run in the background, so in another screen I basically "tail" the logs. 2nd. script does the same but takes some user inputs interactively. Note that none of these scripts perform any sys admin activities, nor do they require root privileges.
Priority is 1st. script - I was wondering if it's possible to build a servlet, which can invoke this script and thus I can deploy the servlet/jsp page combination in some web-server within the UNIX machine and be able to access it from my Windows PC, Firefox/IE. Once started, the servlet can do either (a) Provide a link which links to the log-file (b) Automatically do a page change and start showing the log-file.
Is this possible and if yes if some help can be provided - much appreciated.
2nd. script I believe would be a bit complex as the servlet need to capture user inputs and actually "mirror" the shell script queries back to the client. If any help can be rendered for this too, much appreciated.
An important detail - the parameters for the 1st. script can not be hard-coded but need to be provided as an option to user, since the options can change with situation.
Again - thanking you in advance.

    ProcessBuilder pb1 = new ProcessBuilder("script1.sh "+param1+" "+param2);
    Process p1 = pb1.start();
    p1.waitFor() // in case you want to wait for completion of the shell script
    ProcessBuilder pb2 = new ProcessBuilder("script2.sh "+param1+" "+param2);
    Process p2 = pb2.start();
    PrintWriter pw = new PrintWriter(p2.getOutputStream(), true);
    pw.println(input1); // input1 is the input expected by the script2.shalso look at the API for ProcessBuilder and Process classes

Consuming a Web Service using JSP and servlet

I have created a Web Service in Netbeans IDE 5.5. I developed a JSP to provide input to the Web Service, and a servlet that will pass the input to the web service through a request and outputs the result.
I am getting the following error:
HTTP Status 500 -

Any hints???

You probably should post to either the NetBeans website mailing list, or the Sun forum that supports the Sun Application Server, as the error is the result of a configuration error of one or both of these products. A file can't be found:

Silent print a PDF from a web page using Flex. We are targeting Windows and Mac with Arcobat reader installed

We are planning to Silent print a PDF from a web page using Flex. We are targeting Windows and Mac with Arcobat reader installed. I have tried using the AIR appliaction and it worked, But our requirement is NO INSTALL to the user machine for the silent printing. It is just from web page and silent printing to the default printer to the desktop/Laptop. Can anyone share your thoughts and experience with us. It will be very helpful..
For AIR : I tried the thread Re: AIR and PDF showing/silent printing

Hey CodeMonkey & Ross,
Did you either of you ever find a solution? I'm stuck too, it seems I can get remote printing on all these PDFs to work but it just prints a blank page since I've been using Javascript in the browser, not Adobe's (they are Engineering drawings that I do not have permission to edit so I can't just insert code into them but I need to make work instructions). I've been scouring the internet for hours now, it seems that this thread is the only relevant/useful one at this point. No one else was trying to achieve this for similar reasons to mine.
Thanks guys,
Lox

How can I add a podcast episode to an existing web page using iWeb?

How can I add an episode to an existing web page using iWeb?
I could probably figure this out but I am afraid if I make changes to the site and re-upload it to the podcast area I will have just doubled it. I see them repeated from time to time.
What is the proper protocal? Thanks

Hi apple-owner,
Method 1.
To create this scatter-plot, I selected the whole of Columns A and B. (Shift click on the Column reference tabs).
The plot ignores blank rows, but they are "ready" for new data:
Method 2
If you did not select whole columns, you can extend the "active" rows. Rows 1-5 selected:
Add more data rows and drag the fill handle (small white circle, bottom right) down

IPhoto still won't make web pages using the comments field

I am someone who makes use of the comments field in iPhoto. I don't edit the title, because I thought it edited the photo file name (perhaps only in earlier iPhoto versions). Unfortunately, the Apple's tools for making a web page from iPhoto '08 seem to still use the title field only and not the comment field. That means that I have to edit all titles (to blank or a proper title) if I just want to show an annotation on just a few photos in a web page. At least the comments field defaults to blank, so I normally use it, along with the Better HTML plugin to make web pages, http://www.geeksrus.com/software/betterhtmlexport/
Now, the web pages produced by Apple are now as good as and even better than the BHTML templates, and I'd like to use them. But this problem with the comments means I can't quickly convert my old photo albums to something that makes nice web pages using my annotations with the iPhoto tools.
Does anybody know of any solutions to this problem? E.g. a script to copy the comments field to the title field?

I know what you mean. I can't believe that after so many versions of iPhoto that have supported publishing of some sort that such a basic and obvious feature still hasn't been implemented. It can't take that much effort to add. I'd rather have that than the new (and IMHO completely useless) "Events" feature. Speaking of which, does anyone know if there is a way to turn it off? It's annoying the heck outta me. I hate it.

How to embed 3D models in web page using JAVA?

Hello
I'm doing a project at University to create a virtual tour of a village. I am creating the buildings in MAYA using polygon planes and cubes and then exporting to VRML.
I plan to embed each individual model into a separate web page. Then when the user clicks on a location in a 2D map they will be taken to the web page containing that building.
However, I can't work out how to embed these 3D models into web pages using JAVA. Can anyone help me with this, please?
Also, I've been told to use JAVA 3D to interact with the project but am unclear as to how JAVA 3D would be used in this project - aqny ideas/suggestions welcome!
M.

If you use Java-plugin, you can embed Java3D in a web page.
Here is the URL(http://www.geovista.psu.edu/products/demos/LorenzAttractor3D/index.html) which used Java3D.
I hope this helps.

Resizing pixs for web page use

I have resized the photos to use on MS Frontpage but when the thumbnails are clicked on to be enlarged in the web page they are still too large. How do I make photos usable for web page use?

What version of Elements are you using? How are you now going about creating the thumbnails and larger images? What size are you making the large ones? I suspect all you need to do is change the width and height parameters to something smaller.

I want to make a web page using labview.

I want to make a web page using labview. I have the internet tool kit. Where do I start. Till now all I have used labview is for industrial I/O and mmi. I have used various TCP UDP comms for network purposes, but I haven't ever done anything with Web page design.

The internet toolkit has some functions for generating and manipulating HTML, but it isn't really intended as a Web page authoring tool. I personally wouldn't use it for such a purpose, and I've done a good bit of Web programming in various different environments, including LabVIEW.
The true power of the internet toolkit lies in its ability to create LabVIEW VIs to handle CGI requests, the way that perl or PHP might be used in more traditional Web development. In the old days, this was really the only way to provide Web interactivity with LabVIEW on the back end. Here is a document that outlines how to start up the toolkit's Web server and check out the CGI examples that ship with LabVIEW. This is the best jumping-off point for creating your own pages, if you are planning to use the CGI functionality in the internet toolkit. Just examine how the HTML pages and the CGI VIs in the examples work together and begin to try out your own VIs.
Since LabVIEW 6i, LabVIEW has shipped with Remote Panel functionality that allows you to publish any LabVIEW VI in a Web browser without the burden of creating special CGI functionality. Furthermore, users can fully interact with the VI--buttons, graphs, string controls, etc. That's really a better solution if you want to make VIs available via the Web and aren't so much interested in CGI/transactional behavior. Check this out by choosing Tools >> Web Publishing Tool from LabVIEW.
I hope this info gives you some ideas about starting points for Web functionality in LabVIEW. Please follow up if you have more specific questions.
Best Regards,
John

How to open a web page using indesigncs3 javascript ?

Create an entire web page using cffile

I would like to create an entire web page using cffile..
it seems that the output attribute is where you put the
content like:
output="this is a test."
Q: so how do you add the full .htm content inside ....
output=""
... where there will be lots of other double quotes?
(if it involves 'escaping' characters - then I'll need some
help with that.)
Also : is it possible that the content could be some data
combined with an cfinclude - i get errors when i try this...

Well, I dont think I fully understand your intentions or
goals are. However, from what I gather so far, you could output the
data into pdf files. But like I said I dont understand what your
trying to achieve. As far as the errors with <..etc, if they are
included and you are trying to produce results those characters
very well could cause problems when you are trying to do something
that they were not intended to do.

Controlling shockwave content (dcr) from a web page using javascript

Hi,
Is it possible to control shockwave content (dcr; object="application/x-director") from a web page using javascript?
I believe this is possible using 'FSCommand' in Flash...
I'd like to use HTML to do something like:
- html_object[1].go(10);
to send playback to frame 10.
Thanks.
Mark

Sean,
Thanks - this is exactly what I was looking for.
'Shockingly' difficult ( pun intended :-)
Someone really put in some effort on this.
Very creative solution, putting a flash ( swf ) component in a director project and communicating indirectly through the flash element.
Apparently, Javascript can communicate with the SWF file & the SWF file can communicate with the DCR file, but it is not possible to have Javascript communicate directly with the DCR. Too bad.
After looking over this example I think I'll rethink my project.
Thanks again.
Mark
