Beginner here
I just managed to set up java and the latest version of tomcat.
I entered: http://localhost:8080/
I can see the start page but the examples won't work. I am getting:
HTTP Status 404 - /jsp-examples/
type Status report
message /jsp-examples/
description The requested resource (/jsp-examples/) is not available.
Apache Tomcat/5.5.16
What did I do wrong?
What did I do wrong?Click on the link of Tomcat Manager and see if the jsp-examples show up in the list of deployed applications. If not, there is some problem with the installation and you would need to create the deployment yourself.

Very confused beginner here...
Hello everyone. I'm new to the board here. I am currently a junior meteorology major with a minor in computer science at Millersville University. To incorporate both my minor and major, I decided to make a computer program that scrolls weather watches and warnings across the bottom of a computer screen (much like they do on television). I am a beginner at Java, only using it for a few months. I really feel like I have bitten off more than I can chew with this program. However, I am dedicated in working through this problem. Below is a copy of the code I am using for this. I keep getting errors, however. I had it working perfectly, besides the fact that a) it never updated and b) it would never scroll more than one watch or warning, meaning it would just loop one over and over. I have also included the errors that I receive during this. Any help would be greatly appreciated. I am sorry if the code looks a bit trashy and disorganized. These are just some things, being a rookie, that I am going to have to learn how to clean up. Thanks

I will say this: it's a confused mess. There's too much code and too little abstraction. This is typical of beginning object-oriented programmers.
When you start seeing LOTS of repeated stuff like this:
if (newscroll.contains("Tornado warning".toUpperCase()))
scrollLabel.setBackground(red);
}alarm bells should start ringing in your head. It appears that a Map with a String as key and Color as value is wanted. I can make all that code collapse into something MUCH smaller. If I externalize all those awful Color declarations into a File that's read on startup (e.g., taking in the key message and the RGB values and initializing the Map), now I have something that I can change more easily. AND there's less code to manage.
I see URLs, applet, TimerTask, HTML - the kitchen sink.
I can't tell you what this class is about.
Be lazier - write less code. That's what good programmers do.
Try to think more abstractly.

Beginner here - build to FLASH - video tracks missing sound?
OK...was reading some other forum entries on audio problems...way over my head...here goes my problem:
I can see it all working perfectly (including all sound) under Encore's preview all the sound for the videos are there...sound for Main Menu...sound for Secondary Menu...sound for slide show...sound for videos...I did a ULTRA build...
After doing a Flash build...which looked like it completed normally...I brought the .html file up...all the functionality works EXCEPT...no sound for the video clips.
Any ideas why? If you have an answer please dummie it down for me!
Thanks, --billDavid,
My hat is off to you for persevering with Encore 3 and getting it to output flash video. AFter reading that you had gotten it to work, I was inspired to try once again. This time I encoded my timeline to DVCPro HD by exporting the FCP project to Compressor. I then took this timeline (an 11 minute video) into Encore 3 and tried to build a flash DVD. I have a main menu and scene selection menu, and they both transcoded fine in about 20 minutes, but once again when Encore got to my timeline, the progress bar moved to about 1-2% and simply stayed there. After 7 hours I finally gave up and canceled the transcode which had never progressed any further and did a Force Quit on Encore.
I noticed in doing the above, that during the transcode of the menus Activity Monitor shows my cpu is reading 170-190 and varying as you would expect. Once Encore hits my timeline and begins the transcode of that, the cpu drops to 100 and remains there with no real sign of activity.
Can you tell me if your DVD that you successfully output to flash with Encore 3 had chapter marks in it? I am wondering if they could be the trouble. Some people have indicated that they solved the problem by going back to an earlier version of Quicktime. I am using version 7.5 of Quicktime, which is the latest version. Can you tell me what version of Quicktime you are using on the Mac that succeeded in outputting to Flash video using Encore 3?
Thanks again for your help.

Beginner Here With A few Questions
Hey everyone,
I am just beginning in the web design industry and could use
a little help with some terminology.
1) If you want to create a site like say "MySpace" with
thousands of "User Accounts" with their own user name, password,
and email address, what do you call those type of accounts? Are
they difficult to create once the site is up and running?
2) If you want to add Ecommerce to those accounts to aquire a
monthly fee, is that difficult and what is the best way to do it
with dreamweaver and tool box?
Any and all help is appreciated....

How do I publish an iMovie to YouTube? (Beginner here and I keep getting a communication error)
When publishing iMovie to YouTube I keep getting a communication error at the end saying to make sure I am connected to the internet. Can anyone tell me why this is?
Thanks for your reply Matt, that is what I have been doing, but I was really hoping it would be possible to do this from the Sharing menu on either or both of my iPhone or iMovie.
I guess I shall be disappointed yet again. As so often, "So much promise, so little delivery." -
Hi,
I am working in ADF 11g, OIM Self Service Control.
Can anyone provide me some material on OIM, as how to create Groups and provisiong Users to Groups.
Also, can anyone help me in understanding the relation between OIM, OAM, OID.
Early response is appreciated.
Thanks
Edited by: user617801 on Mar 16, 2009 8:46 AMHi,
You need to go to documentation section of oracle and get OIM/OAM/OID documentation. On this forum one could not give a lot of info and this forum is platform to discuss any issue or any conceptual questions.
Just go through documentation and if you are biggener then you must attend some oracle training or start with small development and understand bit and pieces of Identity Management systems.

Applescript beginner here: Opening files
I'm progressing slowly. One area I am stuck on is file operations. Part of my current effort is to write a script to go like this:
Launch Adobe Photoshop CS3
Do File New
Automatically Press OK button in resulting dialog box
Paste into Photoshop the contents of the clipboard
Seems simple, by I am flummoxed in getting Photoshop (or any application) to select menu items. I have seen no info on that, and even if there was a scriptable dictionery item for Photoshop filehandling, I can't yet decipher the syntax in dictioneries. For example:
"move v : Move object(s) to a new location
move specifier : the object(s) to move
to location specifier : the new location for the object(s)
→ specifier : to the object(s) after they have been moved" ?????
Therefore, can anyone suggest a script that would do the bit in bold type above;
And, can anyone recommend a book for absolute beginners in Applescript (Dummies, Applescript for Applications: Visual quickstart Guide (2001 !)

How to Remove “Other” Data from iPhone, iPad and iPod Touch

With an iOS device, the “Other” space in iTunes is used to store things like documents, settings, caches, and a few other important items. If you sync lots of documents to apps like GoodReader, DropCopy, or anything else that reads external files, your storage use can skyrocket. With iOS 5/6/7, you can see exactly which applications are taking up the most space. Just head to Settings > General > Usage, and tap the button labeled Show All Apps. The storage section will show you the app and how much storage space it is taking up. Tap on the app name to get a description of the additional storage space being used by the app’s documents and data. You can remove the storage-hogging application and all of its data directly from this screen, or manually remove the data by opening the app. Some applications, especially those designed by Apple, will allow you to remove stored data by swiping from left to right on the item to reveal a Delete button.

Beginner Question: How to put 5 V on an output?
Hi everybody,
I am an absolute beginner here, a Biology student that has to do electronics in Labview now...
I want to do as much of this myself as possible, but need truly beginners hints, hoping to be clever enough to put it together myself with your information.
I need to control some outputs, and monitor some inputs. I am focusing on the outputs at the moment.
Questions:
How do I make a block in my block diagram that can put a variable voltage on an output? I need two controls, one that puts a voltage on an output of 0 to 10 V continuously, the other puts a voltage on an output of 0 to 5 V in increments of 0.1 V
Any hints will be highly appreciated. I have Labview 6 to work with. Pointers like 'look at p
age XX of the manual' will do, but descriptions here, or through my mail... anything will be highly appreciated.
Thanks in advanceIn article <[email protected]>,

Well, for me and my past gigs this has been a very common situation. When
I worked for telecom we would have to develop apps for instruments that we
wouldn't receive for six months. Luckily we had the basic concept of how
they were supposed to run and this was adequate for development. It
sounds like you're in a similar situation.

Lemme see if I understand you from this post and your first one. You
would like to buid a user interface that includes the following:
1) A boolean control that gives these two options:
a) output a continuous voltage in the range of 0-10 volts b) output a
ramping voltage starting at 0 (or 0.1) volts and ending at
5 volts using 0.1 volt increments with a dwell time of x mseconds
2) A boolean to stop the application
(perhaps another one to pause it)
3) Several numeric controls:
a) numeric control for the output voltage b) numeric control for the
dwell time (optional) c) numeric control for the voltage increments
(optional) for if the
user wants to use values other than 0.1 volts
4) An indicator that shows what the measured output voltage is. This is
good for verifying your output signal. A chart would be nice.
This is a top down approach which is helpful for laying out the
application's user interface. The next thing you want to do is build some
subVIs to simulate your voltage signals. Once you get some hardware you
can simply replace these simulation subVIs with the real ones that
actually communicate the hardware.
I'm not sure if your measuring the output voltage too. I kinda just
assumed this but that would require another subVI. I won't tell you how
to build the subVIs (I can't take all the fun out this) but I hope I've
pointed you in the right direction.
Merry x-mas!
-Kevin
PS: learn how to play with control references. they're very convenient
when you need to update the front panel indicators with data from a subVI
sitting in its own continuous loop. it avoids global variable abuse. -
Java Program to copy file from one directory to another failing
Hello All,
Oracle Applications 12.1.3
RDBMS: 11.2.0.30
SQL*Plus: 10.1.0.5.0
Java beginner here so help is much appreciated. I'm have some java code that I'm using to copy a file from one directory to another in an Oracle Applications Server. I notice that when moving to a new instnace I started to get file not found errors. I think it's because of the directory. My question is, does the directory in which I trying to pick up the file have to be a DBA_DIRECTORY, or a UTL_FILE directory in order for the java to find the file and move it?
Here is my code...
CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "COPY_FILE_JVS" AS
import java.io.*;
public class COPY_FILE_JVC{
public static void copy(String SourceFile, String DestDir) {
File source = new File(SourceFile);
File dest = new File(DestDir);
File cpDestFile = null;
try {
if (dest.isDirectory()) {
if(source.isFile()) {
System.out.println("File name = " + source.getName());

If I change the directory from /home/my_user/ to any directory that is defined in DBA_DIRECTORIES or is a UTL_FILE directory to program works.

Needing help making a Slideshow in Premiere 7
Back in 2008 several contributors on this forum helped me make a slideshow using Photoshop Elements 6 and Premiere Elements 4, which I am forever grateful for. It was a long process as I had never made a slideshow before, but after much labor I created a wonderful slideshow of my Alaska photos with music. After a lot of reading I decided to upgrade to Elements and Premiere 7, which I was able to actually do for free. I purchased the Muvipix.com Guide to Adobe Premiere Elements 7 as I was told this would be a great resource to help me out. Well, here I am two years later trying to make a slideshow again and still as confused as ever. I am trying to make the slideshow in Adobe Premiere Elements, as I was told last time it was easier to do it that way if I wanted to add music to it. I am just getting started and am already confused.
My first question is: Am I best off making the slide show in Premiere Elements rather than Photoshop Elements? I want to add music to it.
I have tried using both the book that came with the program and the Muvipix book and I am lost on step one.
In the Adobe manual it says to deselect the Show Video and Show Audio buttons. Why do I need to deselect these?
In the Muvipix book it tells me to select a number of clips amd then either right-click on them or click on the ">>" button to access the "Create Slideshow" too. I can't find the ">>" button. How do I access the the "Create Slideshow" feature?
I have a question about the stills that show up in the panel. Many actual photos appear in this panel. However, there are also a large group of boxes with two swirling arrows, one green and one red. Why are they there rather than actual photos? I have tried double clicking on a few and they all bring up the same photo folder from "my pictures." I am confused.
Sorry if my questions seem very basic, but this is not what I do for a living. It is a once every couple of year hobby. Perhaps if I ever get it downpat I will do it more often.
Thanks for any help you can give me. I am sure I will need a little more handholding. I have been looking for the last two years for a class on this program. I know that is what I need. However, none have been available in my area.Thanks for the response Steve. I am hoping it will be easier this time around.
"If you're seeing empty boxes with swirling arrows in them instead of your photos in the Project panel, it means that the program no longer has access to the photos -- either because they were moved or the device that they were on (your camera?) was disconnected from the computer. You really need to copy these photos to your computer's hard drive if you're going to use them in a project"
These photos were still on the harddrive. I checked in Photoshop Elements and they needed to get reconnected. Here is what I think happened. When I download my photos, they go into MY PICTURES. When I move them from where they automatically get placed by the program, into a folder of my choice, they seem to get "unconnected". I was able to reconnect them and now they appear in Premiere Elements. Thanks for the tip which actually led me to a solution.
"There are actually at least four different ways to make a slideshow in Premiere Elements and Photoshop Elements. Each has advantages. Which method are you using? (In all cases, as I say in my book, you should make sure your photos are sized to no larger than 1000x 750 pixels in size before you begin.)"
I am just starting and I was using Premiere Elements 7. I thought I was told back in 2008 on this forum it was easier to do it all in Premiere Elements if I wanted to add music rather than creating it in Photoshop Elements and then moving it to Premiere. As far as photo size, I am a real beginner here. I have no idea what size they are or where to look to find that out. All I know is that my Alaska slideshow turned out great and did nothing about changing pixels. Where would I find out how to change pixel size?
"It sounds like you're using the Create Slideshow tool in the Project media panel. (As I say in Chapter 1, you'll only be able to see the >> menus if you go to the Window drop-down menu and select Show Docking Headers.) You can also access this tool by selecting all of the photos you want to include in the Project panel and right-clicking on them."
I did read about Show Docking Headers and did follow that instruction. That was the first thing I did, actually. However, when I am in Premiere ELements, I still don't see where I find the Create Slideshow tool that you mention on p. 59. I am a bit confused with this option. I can move the photos I want from the panel to the Timeline, but I am confused as to where the "Create Slideshow Tool" is located.
Thanks again for your help.I know I will get this done, just very slowly. -
What file type to export vid from final cut to studio pro
Beginner here, the question I have is what is the best file format to export from final cut to studio pro so that I will play in a decent to good quality on a DVD that I make in studio pro. Thanks.
For my FCS projects, I export DV_NTSC "anamorphic" (I use 16:9 format) to a "reference" movie: that is quite fast after all rendering is completed and the resulting file is pretty small. The only disadvantage to "reference" I've found is that you must keep all those FCS file around since those are what is referenced by the export.
I export like that instead of exporting to compressor because for me, exporting directly to compressor is very slow; on my G5 Quad, my compression step is about 1:1 with real time.
You can take those .mov files into DVDSP and let it do the compression using your defaults. I prefer to use Compressor directly so I can set the compression, Dolby, etc. parameters. Compress to mpeg2 and AC3 (Dolby Digital) and if you are just in stereo, just keep it in stereo, check the "no surround encoding" and make sure the highest audio level in either channel is -3db (or the compressor setting let you reduce the level by 3db). That prevents a downmix to mono (like on a cheap TV) from clipping (-3db + -3db = 0db. (zero plus zero = +3db and is clipping).
