PaintComponet(g) in Japplet? thanks- newbie here

Hey guys, I have a JApplet with a series of jpanels. I would like to draw on the various panels independently. The forums have showed me that I need to use the paintComponent() method. well whenever i use the code..
public void paintComponent(Graphics g) {
super.paintComponent(g);
g.drawImage(pic.getImage(),0,0,this);
}it says that Error(433,11): method paintComponent(java.awt.Graphics) not found in class javax.swing.JApplet . What am I doing wrong? Thanks in advance!!!

paintComponent is a method of class JComponent.
JApplet is not derived from JComponent.
Even if it where, it would be a mistake to do that.
JApplet's job is to be a container: it should not be doing the drawing.
Define subclasses of JPanel to do your custom drawing, and have your JApplet function as it normally does.

Hi newb here , Can anyone help with Port Forwardin...

Hi guys
Newb here on Broadband Option 3 .
New to the world of BTorrents ( hope thats not a dirty word ) and just need some help on Port Forwarding with the Curved Blue Voyager ( latest one I think )
Problem is I can't seem to upload anything back and obviously I dont just wanna leech all the time lol
Thanks in advance

First of welcome to BT Community Forums, although your in the help with speed/connection issues section and bit-torrent is nothing to do with BT but i'll still try to help.
downloading a torrent file is one thing but just because you download does'nt mean you need to upload anything if for example your downloading something with say 100 seeders and 15 leechers then you may find that you dont upload anything or very little, thats nothing to worry about at all.
Or
If you've made a torrent and cant figure out why its not uploading it may be due to the fact you need to upload the small torrent file to a p2p site in order for others to see it.
Hope this small insight into the world of torrents helps, but i dont know what else to tell you on this subject.
Kindest Regards

[multithread] newbie here ... is inputStream shared?

Hi, a newbie here. I've been playing with java for six month now and it's been pretty fun. Looking forward to learn more about java from this forum. Now I have a question about this little project I've been doing.
I'm currently developing a multi-threaded client-server application (both client and server are multi-threaded). The idea is very easy which is to create threads that send http request to one server which will send back XML to the
corresponding thread.
I've managed to make it work. My application can now make http request and get the XML it's looking for. However, problem occurs when I try this scenario:
1. Client Thread 1 http request> server -> creates server thread 1
I made Server Thread 1 sleep for awhile so Client Thread 1 has to wait for the response.
Then, while Server Thread 1 is still on sleep, I make another http request:
2. Client Thread 2 http request> server -> creates server thread 2
I again Server Thread 2 sleep for awhile so Client Thread 2 has to wait for the response.
Now, Server Thread 1 wakes up and returns the XML response message. Now the funny thing is the Client Thread that accepts this response is not Client Thread 1, but Client Thread 2:
3. Server Thread 1 wakes up -- XML response --> Client Thread 2 reads the response instead of Client Thread 1.
What could be the problem!? What's also weird to me is that, if I try to do this scenario using a browser (by executing http request), the problem doesn't happen. Client Thread 1 returns to Server Thread 1 and Client Thread 2 returns to Server Thread 2.
The code I wrote consist of a thread objects which has it's own private UrlConnection, InputStream, OutputStream, etc.
This is a snippet of my code:
public class Process {
// this is how I create my threads
public void execute(DataSource datasource, ADData ad)
HttpProcess httpRequestor;
try
httpRequestor = new HttpProcess(datasource,ad);
httpRequestor.start();
catch (Exception e)
e.printStackTrace();
public class HttpProcess extends Thread {
private URL url;
private HttpURLConnection urlConn;
private DataSource ds;
private ADData adData;
private BufferedReader d;
private BufferedWriter t;
private InputStream in;
private OutputStream out;
private DataInputStream din;
private DataOutputStream dout;
public HttpProcess (DataSource datasource, ADData ad)
this.ds = datasource;
this.adData = ad;
// this is how I implement my run method
public void run ()
try
String urlmsg = "http://localhost:9050" +
"/?field1=" + adData.getField1()+
"&field2=" + adData.getField2()+
"&field3="+ adData.getField3();
System.out.print("Sending URL message : " + urlmsg);
url = new URL(urlmsg);
urlConn = (HttpURLConnection)url.openConnection();
urlConn.setRequestMethod("GET");
urlConn.setDoOutput (true);
urlConn.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");
out = new BufferedOutputStream(((HttpURLConnection)urlConn).getOutputStream());
dout = new DataOutputStream(out);
t = new BufferedWriter(new OutputStreamWriter(dout));
t.flush();
while(listening)
in = new BufferedInputStream(((HttpURLConnection)urlConn).getInputStream());
din = new DataInputStream(in);
d = new BufferedReader(new
InputStreamReader(din));
String inputStr;
if ((inputStr = d.readLine())!=null)
din.close();
XMLParser xmlparser = new
XMLParser(ds,adData,ajData);
listening = false;
d.close();
I thought I had it right by having private inputStream for each thread. but the behavior looks like the inputStream is shared by the two threads. However, I'm still new with java so I know my conclusion worth zero. Has anybody ever bumped into this kind of problem? Looking forward to hear back what you guys think. I'm just really really really curious about this problem
Thanks so much.

Please use code tags ([code] and [/code]). It's also quite possible the problem is in your server code, or your test jig, etc. You should post a small example that replicates your problem.
Also, the while(listening) loop looks really screwy. I'm not sure what's going on there (why would you wrap your input stream inside a loop, especially since you close the input stream in the loop)?

Help!!! Newbie here!

Alright. I have CS3 and am 'trying' to get used to it. I am trying to do a vintage effect and of course this takes many steps. One of the steps (almost one of the lasts) is to go to Filter>Distort>Lens Correction AND then from there, use the Vignette Slider, etc...
Well, Under MY Filter, there is NO distort, there was in my CS2, so I dunno what the deal is. I used the Help Search and it found the distort under the Edit>Transform>Distort. BUT, the distort is greyed out! I have tried everything. It IS in 8 bit, I've even tried 16 bit... NOT working. The only time distort even comes up is if I go to another 'blank' layer... and of course, I can't do anything with it! :(
so, what do i need to do to get the distort working... it's there, but it's greyed out. Please help. And I don't know if this will give my email or not, please feel free to email me also with your help! :D thanks!

Hi Macadam_ace,
Welcome to Apple Discussions
Do they have their show on the internet? The iTunes Help document says,
"If you know the Internet address (URL) of an MP3 streaming broadcast, you can connect to it using iTunes.
Choose Advanced > Open Stream.
Enter the full URL of the file you want to listen to. For example, http://www.apple.com/itunes/sample.mp3."

Can I use one hard drive for two computers? Newbie here.

Newbie here.
I currently use Time Machine for my iMac (Intel)
I've been using my Macbook Pro (Intel) a lot lately and would like to back it up from time to time as well.
Can I simply attach the external hard drive to my Macbook Pro and set up Time Machine?
Can use the external hard drive for both machines?
Will Time Machine recognized that my Macbook Pro is a separate computer and set up a separate folder on the external hard drive automatically?
Thanks

Hi,
you can use the drive for as many Macs as you like, just make sure it's big enough. Time Machine will create separate folders for your Macs and will "know" which one you're using.

Newbie Here - Constant Crashing & Can't Load Files CS5.5

A complete newbie here....I have started a project, imported clips, everything works great. I edit my sequence, I've got a create basic edited video. I save the project. That was a great days work....
Now everytime I re-open a project, it sits there loading for what feels like eternity. The video never loads into the "program" viewing area, but I can see the clips and a thumbnail of the clips in the Sequence section below.
And then it crashes while trying to play the program, most of the time.
If it doesn't crash it's simply choppy and I cannot play the program still.
However, if I start from sratch, new project, load clips in, everything plays smoothly so I don't believe it is my hardware that's causing the problem. I'm getting tired of re-editing the same clips over and over.
Suggestions?

Alright...I have some more info...I looked into the windows event viewer...

Flex Newbie Here

I am a complete Flex newbie...so forgive my limited knowledge
while I ask my question! LOL
Here is what I'm trying to do:
I have some data in a database that tracks how many of a
certain item I have.
I want to create a simple flex app that will list these items
and their current count, and when that count changes in the
database, the page automatically reflects the new value without
refreshing my entire page.
From the very limited amount of knowledge I have of Flex so
far, this seems like it should be pretty simple, but I need to get
this running fairly quickly, more quickly than I think I could
learn how to do it on my own. So any help/guidance would be greatly
appreciated!!
Also, on a side note, I have picked up and am starting to
work my way through the Adobe Flex 3 Training from the Source
book...are there any other good resources for learning Flex out
there that anyone could recommend?
Thanks!!

You want to use the Data Management Services for such a
thing.
If your company, does not have the budget for Adobe Livecycle
Data Services (LCDS), you can use Farata Systems' Clear Toolkit
based on the free Blaze DS.

Brain-dead Newbie here...

I would like to create a tool that will drag an image from a webpage to a folder every 20 seconds- for 15 minutes- every afternoon.
I do that by hand now- the images are from a webcam set up watching a nest of barn owlets growing up and eventually fly off. (I'm making a time lapse animation) Last night I got the big idea to automate the image gathering aspect; hours later I was more lost than when I started!
I don't know WHERE to start- the documentation for Automator isn't "newbie simple" for me. I couldn't even figure how to turn the example workflows on! I can deal with Photoshop actions, fancy wired sprites in skinned Quicktime movies, and webby javascript things- but I'm in diapers as far as Automator's process for building a tool is concerned. I'd be thrilled to find a tutorial that makes sense! Any suggestions? Thanks ahead of time.

It's very much task oriented (type of action) and not detailed oriented (how to do action). It takes practice, but letting go of how we are doing it and just identifying the action for the computer to do (however it wants to accomplish that action) really helps when creating Automator workflows. Changing the view of Automator actions to "Category" (instead of "Application") can help when using this approach. On the other hand, I'm sure some would say it's not that at all, that it's instead just a different way of thinking. Oh well, who knows.
Anyways, it sounds like this is what you want, in a somewhat task oriented approach:
1. starting from a web page (not how it's viewed, just start with web page or its URL)
2. get an image (not how to get it, just do it)
3. wait 20 seconds
4. start back over, but stop after 15 minutes
Here is a basic workflow for when you have a constant URL for the web page, but not a constant URL for the image.
1. "Get Specified URLs" (Internet category, or Safari app)
Easiest way to set this is have the page open in Safari and then use the "Current Safari Page" button in this action.
2. "Get Image URLs from Webpage" (Internet category, or Safari app)
In the previous action (step 1), we provided a URL of the webpage with the image we want. This action gets all image URLs from that webpage, but not the images themselves. (Note that we could set this to get any links on the page that lead to images, but that doesn't apply to our needs if the image is already on this page.) You can click on the "Results" button at the bottom of this action to view the URLs obtained when you run the workflow. In fact, go ahead and run the workflow before adding more actions so you can find out URL of the image you want.
3. "Filter URLs" (Internet category, or Safari app)
We probably don't want every image URL found by the previous action in step 2. It's likely we only want one image. You'll set the conditions for isolating that one image from those found in step 2. The easiest criteria is selecting "name" and then "begins with" or "contains", depending on what will match the name (after the last / in the URL) of the desired image but not the other images. This helpful for when the name of the image changes, perhaps because the date and time might be part of the name.
4. "Download URLs" (Internet category, or Safari app)
This is the second part of getting the images. As the name implies, this will download the files pointed to by the URLs. In our case, there should be only one URL that will be downloaded and it'll be an image.
5. "Pause" (Utilities category, or Automator app)
The description of this action doesn't tell you this, but if you try to set the pause to greater than 59 seconds (and press Return) then it'll give you a cryptic error message. You want every 20 seconds, so that shouldn't be a problem.
6. "Loop" (Utilities category, or Automator app)
This will start the workflow over again. Set it to "Loop Automatically" and then either choose the number of times (thrice per minute for 15 minutes is 45 times) or set it for 15 minutes. I would go with the number of times since the workflow likely won't run exactly three times per minute, because it takes time to go through each action. Try a few times (three or four) or a short number of minutes (like one or two) when first testing it out to make sure it's doing what you expect. Also, make sure it's set to "Use the original input" and not the results, because the results aren't URLs and this workflow needs to start with just our specified URL in the first action.
That's it.
Of course, if you discover that the image has the exact same name each time (i.e. the URL to the image doesn't change), then you can shorten the workflow. Essentially, you would start with the URL to the image as the specified URL instead of the webpage. In that case, you obviously wouldn't need "Get Images URLs from Webpage" since the URL is to an image and not a webpage. You also wouldn't need to filter the URLs because there would be only one specified. So, just specify URL, download URL, pause, loop. An easy way to specify the image URL in "Get Specified URLs" is to use its "Current Safari Page" button after opening the image in a new Safari window (just right-click on the image and choose "Open Image in New Window").
However you do it, you'll probably want to save this as an application instead of a workflow so you can run it instantly by double-clicking it, or put it in your Dock. You can edit it again by opening it from within Automator, or drag-n-drop the app onto Automator.

Hi All, newbie here, trying to install Windows 7 on my new iMac, heaps of trouble?

I get to a point where I choose the Bootcamp partition and the error message comes up: Windows cannot be installed to this hard disk space. Windows must be installed on a partition formatted as NTFS.....

Roger
Thanks for the response. I am having heaps of fun here. Got a printer working and printed out the Bootcamp help, which I followed slavishly to no good end. I partitioned the disk, burnt a cd with the Bootcamp data. The Windows 7 loaded as far as the choosing partition to install. The instructions say to go with the Bootcamp partition Disk 0 Partition 3....then I have just read on the next page and it says I choose "format"...so it looks like I have answered my own question. I was clicking on "Next"!!!
Bit dim on a Sunday afternoon here...
Cheers from the great South Land.

Newbie here having input problems

Hi, I'm still very new to Java and I'm basically learning it on my own right now. I think my current problem is with the way I'm reading in the input. Since my entire program right now is over 100 lines, I'll only post how I'm reading input in, and how I'm trying to use the input to continue program execution so that I can verify first if my input is correct before I move on to posting snippets of my program. Here's what I'm trying to do:
//Begin code here
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
String cmd="";
while(//condition)
//Print out input options here
//Read input here
cmd = in.readLine();
cmd.trim();
if((cmd == "A') || (cmd == "a"))
      //Process
else if((cmd == "S") || (cmd == "s"))
        //Process
else if((cmd == "B") || (cmd == "b"))
     //Process
else
      System.out.println("Command not recongnized");
}Based on that code above, is the input reading being done correctly? That's the idea of what I'm trying to do in my program, yet it always just says that it doesn't recognize the command. If need be I will start to post more of my code if this example is not sufficient enough. I'm sorry if this is another one of those cookie cutter answer questions, I've just become somewhat frustrated in the last few hours of trying to figure out why my program isn't working. Thank you for any help you may be able to provide.

Shoot, sorry didn't read over my post before posting as I should have. The snippet:
if((cmd == "A') || (cmd == "a"))
      //Process
}Should read:
if((cmd == "A") || (cmd == "a"))
//Process
Sorry about that.

Complete newbie here

have a clean, wiped hdd....not formatted or partitioned at all...
x86 system, dell gx280, p4, 1gig ram...
i downloaded the five zip files, extracted the isos and burned a dvd w the five iso's on it.
inserted into the dvd rom on the clean system and it won't boot...
question: do i need to fdisk w 98 boot disk to create a primary partition? i want a dual boot system here...would like to put xp pro on a partition & solaris on another...
how many partitions should i have total? primary is xp???? solaris will be on a logical in the extended? vice versa????
i thought the grub boot loader would launch when i set the dvd/cd rom to boot but it wouldn't go. any tips would be appreciated. thanks!

I suggest that instead of just plowing forward and trying to do something
that is completely new to you, that you spend some time preparing for the task.
Read the posts in this forum.
Read every thread from the past year.
Do not post anything, but just read and read and read.
You may not understand every discussion, but you will actually learn
procedures, methods, terminology, and more.
Then go read the posts in the Solaris-on-x86 forum and the Solaris-10 forum, as well.
Next, compare your system to the Hardware Compatibility List.
http://www.sun.com/bigadmin/hcl/
Many system components will have native functionality in Solaris,
but some of your system components may require third-party drivers,
and there is a possibility you may need to replace one or more with compatible hardware.
Third, read the Download And Burning Instructions web page that you may have
bypassed when you got the OS zipfiles.
http://www.sun.com/software/solaris/download_instruction.xml
When you finally get around to installing Solaris, expect to do it
at least five or six times, over and over again. You will learn something new
each time you do that. Don't complicate the issue by wondering about
dual-boot or multi-boot with other OS's. Just install Solaris to the primaty disk,
using the entire drive for the installation. Get comfortable with this OS and you
will acquire competency..
( Were you competent with MS Windows on the very first day you ever touched it ? )

Newbie here, sorry but gotta start somewhere

I created a video file that's 5 mins @ 173 mbs which resides
on my HD.
Right. Okay, instead of sending it through e-mail as an
attachment (it's
way too big anyway) I want to post it, I believe this is
called FTP - not sure.
After posting, I want to create a link that I could send to
whomever through e-mail.
I own Dreamweaver, Go LIve! and have a web-site. Yes, I do
have a web-site but I created the site's layout with the hosting
company's "site creator" program which allows lazy people to make
basic web-pages. So, that's why I'm asking for your help.
Thanks and any advice will be appreciated.

Hi Man
Your first post about the FTP url is a way to go, alright,
but not all hosts allow this mode of transfer as it is not as
secure as others. But if you are goign by way of a new build in DW
as you say, then you have your FTP built-in.
Ok so point by point:
1. - You can imsert your image a few ways. if you want to
layer your other item on top of it your easiet way out is to set
your page margins to 0 (Page properties on the properties
inspector), and insert either a table (pretty basic stuff) or a DIV
(more advanced but ultimately more powerful). You can then set the
image as the backgroudn to this and continue building on top. There
are other ways, but try that first and see how you like it. As you
stadard sizes.... You should search this forum for posts regarding
viewport size/screen resolution. Its probably the hottest
long-standing debate there is. In short there is no such thing. But
i will say thgis and get hammwered by som eof the others for it. If
you are a beginner, giving your page a fixed width is the easiesty
way to go. And the most common resolution is 1024x768. Some use
lower, plenty use higher, but that is the most common. Fact. SO if
you want to design for a set size, design for that. It means width
wise you want to go to around 980 and height approx 650 . Again,
play around and see works for you. Many things can play around with
the viewable area of the screen - the taskbar size and position,
the vewiport size (maximized or not), but eventually you have to
say "Scr** it!" and go for SOMETHING. When you have more experience
under your belt yuou can start worrying about luquid sized sized
that change with the screen size. For now stick with the above, but
as i said, play around with it. You need SOME graphics program, but
only use them to makie and size the image, then insert it into
dreamweaver as is, dont let Fireworks or any other graphics
application create you html for you- its a disaster from the
get-go.
2. - Create the words on the image itself in the graphics
program, and then use whats calle Image Maps in DW to make them
links. This means an area of a page you select (the area over the
word) and this becomes your link, so it looks as though its the
word itself when in fact its a square or circle sitting on top of
the right part of the image.
You know, as i think of it - if you insert the image as a
background as i said just now, you cant use image maps, so perhaps
insert it into a 1x1 table, then insert your second table into THAT
one to hold any other elements you want. Again, you might be better
with DIVS; look into them and see if you think they are somerhing
you can come to grips with yet because for what you are proposing
they make more sense.
3. Not sure what you mean here....can you clarify?
Lastly linking pages - Select the item to be the link,
(hotspot, image or text) and in the Properties Inspector, in the
Link box type the name of the page to link you want to link to, or
better yet hit the Browse button (the folder icon) and find the
file that way. Thats it, you've made your link. You can link to
pages, images, videos, whatever you want (though pages are
obviously the most common).
Best of luck. Post back.
