Desperate help needed with writing files

I need to know how i can write files with an applet to a directory so that i can retrieve the files for later use. I need to know how to do this step by step as i am a beginner. i've tried looking for tutorials and i just can't seem to get it working.
can somebody PLEASE provide me with some valid info here as i'm sure that many others have exactly the same problem and can refer to this topic.
much appreciated.
thnx

You will need a certificate to sign the Applet with.
here is a rehash of the script I use to to this...
CERTIFICATE_FILE_NAME is the name of your certificate file.
c:\windows\.keystorefile is the path & name of your keystore
jar cf tmp.jar *.class *.gif *.jpg *.au
jarsigner -keystore c:\windows\.keystorefile -signedjar YOUR_DESTJARNAME.jar tmp.jar CERTIFICATE_FILE_NAME
del tmp.jar
del *.classThis is excatly what you need to do and your file writes will work.
Now you may need to tweak your getImage to find the files within the
jar but thats another story.

Help needed with .asp files

I am not sure what I am asking or what I need to do, so please bear with me, thanks.
I am helping out with a site that has one dynamic page utilizing a database with an .mdb extension.
Previously hosted on a site with ASP (not sure which version).
New host has MySQL with PHP (?)
I would like to be able to rework the one dynamic page in DW, using .php. I am not able to upload the .mdb file to my localhost MySql area.
It all comes down to the database.....
Is there a way to convert the .mdb file to one with an .sql extension?
Or am I taking the wrong approach?
Thanks,
Melissa

>Previously hosted on a site with ASP (not sure which version).

Are you sure the host doesn't also support .asp?
>I would like to be able to rework the one dynamic
>page in DW, using .php. I am not able to upload the
>.mdb file to my localhost MySql area.
An mdb file is MS Access. There are conversion utilities that will convert between the two dbms's, but if the schema is not complex you can simply build the new database in MySQL, export the data from access and then import it.

Desperate help need with Document Listener

I'm working on a very cool freeware Java text editor, that is working beautifully, except for the code used to change the color of reserved words, etc, on the fly...
At the moment, I use a documentlistener. When text is inserted, I need to color some of that text automatically. However, when I try to call setCharacterAttributes in DefaultStyledDocument, it causes a runtime exception, Illegal State Exception (Attempt to mutate in notification)>
I understand how this exception is caused, but how do I get around it?

Thanks for the replies. They were very helpful, and I have now managed to sort the problem, although in a different way that involves using the key listening class you can add to containers...
The java editor is called j-Scribe, and is a text editor dedicated to java. I've designed it to be more user friendly than other text editors, with a useful interface. The code dispplay is all highlighted, and clicking on a brace collapses that section of code, to make larger classes easier to work through... There are also some nifty filemanagement windows, including a history pane similar to IE6, and one click access to all open files, and one click access to all of their save and close functions... There are wizards to automate creation of certain elements of code, and eventually a number of intelligent features will be added. The program makes extensive use of xml to store all of the information generated by the program.
I'm working on the alpha version right now, for release in about two weeks. The beta will be out three - four weeks after that, and the release should be late September / early October time...
If you're interested, e-mail me and I'll add you to the list for the alpha and beta test releases...

Help needed with jar file

hi, first of all sorry if my post is in wrong forum...but my application is done using swing so i am posting this here....and regarding my question...
I have made an GUI using Java swings and my application is working fine. Now i want to make an executable jar file for my GUI. I have read some tutorilas on making jar files and this is what i have done...
i have created a manifest file called mainClass.txt which has
Main-Class: MainWindow ,where MainWindow is my main class name.
Then i ran the jar utility with this command line:
jar cmf mainClass.txt example.jar *.class
With this line, I told jar to create a JAR file (option c) with modifications to the manifest file (option m) as specified within mainClass.txt, naming the JAR file (option f) as example.jar and including everything that matches the pattern *Class
everything is file till now but my problem is ...I have some library files from JFreechart software included in my GUI to generate barcharts..How can i include these library files in my example.jar file..
Kindly help me
Thanks
byee

I had this problem too. I ran my program out of JCreator and it worked flawlessly. I jarred it up into and Executable Jar and I would get a runtime error explaning I have not included the correct libraries.
What I did was look at the error, for example say it said something like:
org.uhoh.PathSys ClassDefNotFound (or something similar to this)
What I did was extract the library that contained that class file. Then in my project file where I kept my classes I made the folder org, then in org I made uhoh. Inside uhoh I copied over PathSys.class.
I hope I addressed the problem you speak of. I am only a novice but this is how I figured it out. If anyone knows a better way let us know =D

Help needed with audio files in pdf

I added mp3 audio files to a multi page pdf document via Acrobat Pro and the files play fine for me when I open the pdf. My client, however, doesn't even see the audio player rectangles after opening the pdf. Is there something I'm missing to make these files play for everyone who opens the document, every time? My client prefers that the audio files be embedded in the pdf, rather than using links.

Hi The CountryCamera,
Do you know how your client is opening the PDF files with the embedded audio (Reader, Acrobat on Mac OS or Windows)?
If your client is on Mac OS, please check out this thread: Re: Audio files not showing/working on a Mac - solution?
Best,

Help needed with DWT file

Please can you help, made initial template for my website but now I want to change template so I can edit meta tags (tags were originally an unetitable area).
When I apply my example below in the DWT file and apply to all pages the meta tags disappear.
Please can you help.
Currently have..
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="keywords" content="keywords are here" />
<meta name="description" content="description is here" />

<title>Title</title>

<link href="../css-file/css.css" rel="stylesheet" type="text/css" />

</head>
And tried this but meta tags in pages disppear..
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link href="../css-file/css.css" rel="stylesheet" type="text/css" />

<title>Title</title>
<meta name="keywords" content="keywords are here" />
<meta name="description" content="description is here" />


</head>
As always, thanks in advance.

I've placed another example below, would this be correct.
Move the charset <meta> tag and link to the style sheet below the title like this:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>

<title>Title</title>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link href="../css-file/css.css" rel="stylesheet" type="text/css" />

</head>
When you say don't put anything in the head of the document do you also mean taking out the title and reference to the external css file.
No, I was responding directly to your question about the keywords and description. It's perfectly OK to put other things in the non-editable part of the <head>. But anything that you want to be able to change in child pages should be added directly to the child page. That's why Dreamweaver creates the second editable region called "head". By default, it's empty; but it's where you add things like keywords, extra style sheets, and JavaScript to individual child pages.

Urgent help needed with class file platform transfer

Hi,
I am working at home on Java in the windows (2000) system. Now I have compiled a java source code which compiles fine. This is an applet and works fine.
However, when I am uploading the files( class files generated and the html file) to the Sun Unix system, the applet does not work. My first question is: Does this class file generated in Windows system not transferable in the Unix system?
At this point, I uploaded the java source file to the Unix system. The source file has been created in Textpad in the Windows environment. Now using telnet I used the javac command to compile the source file in Unix system. Now, I am seeing three errors which was not the case in the Windows environment? I have no idea why the same source code is working on one platform and producing error in another?
Any help is highly appreciated. Thanks. Regards.

What are the errors?

Help needed with deleted files

Hi all
Still a novice, though have been using Aperture successfully for a few weeks now...
I have somehow (and I am still trying to go back and work out how) managed to delete a whole named project with all the photos in it.
I went from one project to another, in order to continue editing, but when I used the control back arrow and delete button to delete 1 photo that was highlighted, it deleted all the photos and the project (or so it seems).
Where can it be, is it lost for ever, and if it isn't how can I retrieve it?
Thanks
Ruth

Any other ideas? Still can't find them.....reading the manual to see if that gives me any more clues too!
Despairing now!!
Please help!

Java Web Start help needed about writing files?

Hi there! I have this java web start app. i have implemented the File Open service succesfully using the JNLP API but i cant seem to get the File Save Service to work. Basically I have an object in the system which I want it to be serialised to a file on the user's desktop.
       FileSaveService fss;
         try {
             fss = (FileSaveService)ServiceManager.lookup
                                   ("javax.jnlp.FileSaveService");
         } catch (UnavailableServiceException e) {
            fss = null;
        if (fss != null) {
            try {
            FileContents fc = null;
            FileContents newfc = fss.saveFileDialog(null, null,
            fc.getInputStream(), "newFileName.txt");
            FileIO io = new FileIO();
            io.write("new123.nod", r.getTree()); /// my object is r.getTree() !!!
            } catch (Exception e) {
                  e.printStackTrace();
        }My Object (r.getTree) is basically an array. But I cant save it because the saveFileDialog method accepts ObjectInputStream as a parameter?! Any ideas? Thanks!

does anyone know? It actually doesnt even open the Save dialog?? why is that?

Desperate help needed with quote create issues ...

Dear SD experts
I am trying to create a quote using 'BAPI_QUOTATION_CREATEFROMDATA2' in the test mode.
I am entering the bear minimum required (without opening any parameters other than the default
which are QUOTATION_HEADER_IN and QUOTATION_PARTNERS.
The problem that I am seeing is with QUOTATION_PARTNERS-ITM_NUMBER.
When I give QUOTATION_PARTNERS-ITM_NUMBER = '0000000' and run, I get a bogus
message that the quote (with a number assigned) is created. But when I try to open using VA23
it is not and even the table 'VBAK' doesn't have an entry for this.
However when I change QUOTATION_PARTNERS-ITM_NUMBER = '0000020' where 000020 is a valid value, I get a message that says "112 Please enter sold-to party or ship-to party".
What I don't understand is how this ITM_NUMBER "item number of SD document" is connected
to ship-to variable. How can I make sure that these two have proper relationship in the database.
Any suggestions or comments will be highly appreciated.
Thanks
Ram

Desperate help needed with insertion sort code

Here is my insertion sort code for a doubly linked list that does not work. I cannot figure out why and I've been trying everything for the last 10 hours! Please Please help..
public void insertionSort()
    Node pointer=head;
    while(pointer.next!=null)
        Node insert=pointer.next;
        if (insert.item.compareTo(pointer.item)>0)
            pointer=pointer.next;
        else
            insert.prev.next=insert.next;
            insert.next.prev=insert.prev;
            if (head.item.compareTo(insert.item)>0)
                insert.next=head;
                insert.prev=null;
                head.prev=insert;
                head=insert;
            Node current =head.next;
            while (current.item.compareTo(insert.item)<0)
                current=current.next;
            insert.next=current;
            insert.prev=current.prev;
            current.prev.next=insert;
            current.prev=insert;
}

It makes sense tracing it out on paper, running it,
the program never ends.This means that there is an infinite loop somewhere in your code. Find the loops and put some System.out.println()'s in them to see where it's going wrong.

Help needed for writing query

help needed for writing query
i have the following tables(with data) as mentioned below
FK*-foregin key (SUBJECTS)
FK**-foregin key (COMBINATION)
1)SUBJECTS(table name)
SUB_ID(NUMBER) SUB_CODE(VARCHAR2) SUB_NAME (VARCHAR2)

2)COMBINATION
COMB_ID(NUMBER) COMB_NAME(VARCHAR2) SUB_ID1(NUMBER(FK*)) SUB_ID2(NUMBER(FK*)) SUB_ID3(NUMBER(FK*)) SUBJ_ID4(NUMBER(FK*))
383           S1      9           4           2           3
384           S2      4           2           5           3
---------I actually designed the ABOVE table also like this
3) a)COMBINATION
COMB_ID(NUMBER) COMB_NAME(VARCHAR2)
383           S1
384           S2
b)COMBINATION_DET
COMBDET_ID(NUMBER) COMB_ID(FK**) SUB_ID(FK*)
1               383          9

8               384          3
Business rule: a combination consists of a maximum of 4 subjects (must contain)
and the user is less relevant to a COMB_NAME(name of combinations) but user need
the subjects contained in combinations
i need the following output
COMB_ID COMB_NAME SUBJECT1 SUBJECT2      SUBJECT3      SUBJECT4
383     S1     Biology Chemistry      Computer Science Physics
384     S2     Chemistry Computer Science Mathematics Physics
or even this is enough(what i actually needed)
COMB_ID     subjects
383           Biology,Chemistry,Computer Science,Physics
384           Chemistry,Computer Science,Mathematics,Physics
you can use any of the COMBINATION table(either (2) or (3))
and i want to know
1)which design is good in this case
(i think SUB_ID1,SUB_ID2,SUB_ID3,SUB_ID4 is not a
good method to link with same table but if 4 subjects only(and must) comes
detail table is not neccessary )
now i am achieving the result by program-coding in C# after getting the rows from oracle
i am using oracle 9i (also ODP.NET)
i want to know how can i get the result in the stored procedure itsef.
2)how it could be designed in any other way.
any help/suggestion is welcome
thanks for your time --Pradeesh

Well I forgot the table-alias, here now with:
SELECT C.COMB_ID
, C.COMB_NAME
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID1) AS SUBJECT_NAME1
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID2) AS SUBJECT_NAME2
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID3) AS SUBJECT_NAME3
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID4) AS SUBJECT_NAME4
FROM COMBINATION C;
As you need exactly 4 subjects, the columns-solution is just fine I would say.

Help needed with itunes

help needed with itunes please tryed to move my itunes libary to my external hard drive itunes move ok and runs fin but i have none of my music or apps or anything all my stuff is in the itunes folder on my external hard drive but there is nothing on ituns how do i get it back help,please

(Make sure the Music (top left) library is selected before beginning this.)
If you have bad song links in your library, hilite them and hit the delete button. Then locate the folder(s) where your music is located and drag and drop into the large library window in iTunes ( where your tracks show up). This will force the tunes into iTunes. Before you start, check your preferences in iTunes specifically under the"Advanced" tab, general settings. I prefer that the 1st 2 boxes are unchecked. (Keep iTunes Music folder organized & Copy files to iTunes Music folder when adding to library). They are designed to let iTunes manage your library. I prefer to manage it myself. Suit yourself. If there is a way for iTunes to restore broken links other than locating one song at a time I haven't found it yet. (I wish Apple would fix this, as I have used that feature in other apps.) This is the way I do it and I have approx. 25,000 songs and podcasts and videos at present. Hope this helps.
