VERY SIMPLE QUESTION REGARDING UML DIAGRAMS IN JDEVELOPER

Hello there,
I have a very simple question. I want to know how I can convert a class diagram that I have created in jdeveloper into a jpg image so I can put in word. When I try exporting it only has the uml to xmi option
Does anyone have a suggestion?

Hi,
Right mouse click on the class diagram,
than click publish diagram on the context menu
and save as jpg where ever you want...

Very simple question, how do you configure windows 8.1 to use a SF card as the default install location for software applications?

Very simple question, how do you configure windows 8.1 to use a SD card / external drive as the default install location for software applications? Primarily interested in apps installed from the windows store. This should be available in the settings
charm within the windows store. This must have been overlooked in the development of windows 8.1 or is a bug.

I've tried modifying this key and the path:

The registry method does not work with 8.1. I found this out the hard way. Doing it on 8.1 will leave you reinstalling the OS if you didn't do a SRP beforehand.

A very very very simple question

Hi guys,
I have a very simple question and standard but I cant find anywhere...
I have two dateTime variables, i need to calculate difference between this dates in days, thats it.
I tried all functions and tried without success a Java Embed task but I couldnt retrieve this objects as java.util.Date so I couldnt calculate exactly the difference in days like this pure java code:
(dataVencimento.getTime() - dataReferencia.getTime()) / 86400000L)
can you help me this?

Hi Jose
Just see if these alternate approaches works. I know there may be lot like this and you may be lucky to find out simple out of box solution itself. If you want to solve this issue and move ahead, gives these approaches a shot.
1. Create a very simple standalone WebService that takes 2 input date elements (can be of Date type or String type. If string type, convert to date in your java code). Create a simple operation like getDaysBetween(firstDate, secondDate). In the generated webservice impl class, use the java code apis (refer earlier link for usage), and get the difference. Return this value. NOW, invoke this WebService in your BPEL Process, and pass your 2 inputs (if the bpel payload elemetns are date object or string objects of date), and get output, and then use this output in your continuing bpel process.
2. This approach, I did a long back. When we insert any expression using XPath, in that editor window on bottom right side, we see many categories and for each category we see list of functions we can use, like for String, we can use concat etc. I vaguely remember reading somewhere, that we can add our own custom functions also in this section. So explore this direction and see if you can add your own function and then use that fucntion with your 2 input dates.
I have not given solution to your problem, but may be these directions can help you move ahead. Or something along these lines.

A very simple question..Very Urgent

HI,
I have a very simple question.I am able to set up the client authentication as well as server authentication. Now do i need to authenticate (both server as well as client auth.) for every request i send to the server on https...i think it should be like that it should authenticate only for the first time and for the next upcoming requests in same session should not require any server or client authentication.. i think as it happens in browsers..
what is the fact actually??..can somebody put some light...right now in my case it is authenticating for every requests..
This is what i have done..
/****constructor part********/
// and tm are arrays of keymanagers and trustmanagers for client keystore and truststore
sslContext.init(km, tm, null);
HttpsURLConnection.setDefaultSSLSocketFactory(ssf);
HttpsURLConnection.setDefaultHostnameVerifier(new MYHostNameVerifier());
/****Method to send the request and response*********/
urlConn = (HttpsURLConnection)url.openConnection();
urlConn.setDoInput(true);
urlConn.setDoOutput(true);
OutputStream os = urlConn.getOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(os);
oos.writeObject(someobject);
oos.flush();
InputStream is1 = urlConn.getInputStream();
ObjectInputStream ois = new ObjectInputStream(is1);
SomeObject retObj = null;
retObj = (SomeObject)ois.readObject();
ois.close();
System.out.println("Get String>>>>> "+retObj.getString());
I am creating the object of this class..and calling the method again and again for sending requests and response..so i think handshake everytime i call the method...what i want is that handshake should happen for the first time and for the next requests no handshake or certificates should be checked or processed..
is it possible ..how..what i need to do for that..
please help me in this..

I am a Chinese student in a university.I have a very simple question to ask.
I have writed a EJB module,and I have deployed to Weblogic8.1 successfully.
1.Now I want to write a client program.Is it necessary that the client program is packaged in the EJB package.For example ,the EJB package is Beans,is "package Beans " or "import Beans.*" necessary in my client program.
2.If I only know the EJB interfaces,that means the EJB module is writed by other programer.I want to know how I can write the client program.How can I call EJB module's method writed by other programer.Could you give me a simple example?

HT4753 I have a very simple question: how do I view where Lion has autosaved my current version to (without the convoluted route of using finder)? In days gone by i'd simply use the save as function to see where it was being saved.

I have a very simple question: how do I view where Lion has autosaved my current version to (without the convoluted route of using finder)? In days gone by i'd simply use the save as function to see where it was being saved.

It's actually even easier than using Save As to see the full path to the currently open document. Just do a "Secondary click" on the document title in its window's title bar.
Like you, I relied upon Save As my whole life to check a file's location and considered it a must-have capability. Turns out it's even faster to use the single-click method to reveal the full path to the open document. It displays the entire path to the current document starting from the level of your Mac, and works for files stored on drives as well as iCloud.
If you're not sure how to do a secondary click, go into System Preferences, select Trackpad, Point & Click to find the current preference for secondary click on your Mac. If you happen to have a mouse with more than one button, it's probably the right button. As a trackpad user, I check the box to "Click or tap with two fingers," so a simple two finger tap on the title of an open document reveals its full path. This feature actually has been around for a very long time.
Note that this is not the same thing as the Autosave and Versions menu, which is exposed using a little drop down triangle to the right of the title. There is no visual clue for the presence of this feature - you just have to know it's there, probably because this feature goes all the way back to pre-OS X days.

UML diagrams using Jdeveloper 9.0.3

I would like to get some help from people who have used Jdeveloper 9.0.3 for creating UML diagrams.
scenario
I have 2 packages namely com.pack.bo and com.pack.ejb created using Jdev.
I have business objects represented in UML inside bo package and have SB's inside ejb package.
Now how would i show the relationships from ejb's to bo's diagramatically ?
Is there any way to show the above mentioned ?
Thanks

Hi,
You could use the Dependency relationship to show the connection on a diagram. Also you could use Notes and Note Attachements to further annotate any relationship.

A very basic question regarding data block

Hi All,
I've a very basic question concerning data blocks in oracle forms 10g.
I want to make a view only screen (only query allowed, no update, insert or delete).
I'll have 6-7 fields on the screen but all the fields are not from a single table.
For e.g, let say we've field names to display on the screen are f1, f2, f3, f4..
Out of this f1 and f2 will come from table A and f3, f4 will come from table B.
Now, my question : Is it possible to create a data block using the data block wizard for such situation if we select create data block from table options?
If no, can you please tell me an approach to do this.
Regards,
Navnit

Hello ,
First write your query & select datablock property.
just change the below properties
Query Data Source Type=From Clause Query
Query Data Source Name = (Paste query here)
now you should add the block ITEMs and give their names according to query columns names. shows the column on canvas and run..
Best Regard

Very simple question from a rookie

Hi,
I don't know how sequences work in OWB.
I have a very simple mapping:
1 (not empty) source table, 1 (empty) target table, 1 sequence.
Source and destination are connected.
The sequence.nextval is connected to the primary key. sequence.currval is not connected.
When I run the debug mode an error occurs: "Could not find data for all sources and target ...". The "Test Data" shows that OWB has not found data for the sequence.
Help!

I use 10gR2 and OWB 10.2
The tables and the sequence are deployed. They are in the database.
There's something strange about this:
Starting ("Start...") works.
The debugging does not work.
Problem nearly solved ...

Very simple question from a beginner

I am currently doing a little exercise, but I ran into a problem. I have written a class that supports operations on rational number. The fields are two long variables, one each that stores the numerator and denominator.
I have made add, subtract, multiply, and divide methods...
1. what I need help in is: beingh able to store the rational number in reduced for, with the denominator always positive
2. constructing a toString method, equals method, and compareTo method.
3. it also says "make sure the toString method correctly handles the case in which the denominator is zero by throwing an exception.
I have been working on this for a long time now, an I am stuck at this point.
I know this will be very simple for you guys and gals, but I am a beginner. Please offer some input, advice, and/or some code to help me get past this problem.
Thanks so much,
Jason

ok, here is what I have so far
public class Rational {
     public long num, den;
     public Rational(long n,long d) {
          this.num = n;
          this.den = d;
     public static void main(String args[]) {
          Rational r = new Rational(1,2);
          Rational s = new Rational(3,4);
          Rational rmuls = r.multiply(s);
          Rational rdivs = r.divide(s);
          Rational radds = r.add(s);
          Rational rsubs = r.subtract(s);
          r.print();
          s.print();
          rmuls.print();
          rdivs.print();
          radds.print();
          rsubs.print();
     public void print(){
          System.out.println(this.num+ "/" +this.den);
     public Rational multiply(Rational t){
          long n;
          long d;
          n = this.num*t.num;
          d = this.den*t.den;
          Rational answer = new Rational(n,d);
          return answer;
     public Rational divide(Rational t){
          long n;
          long d;
          n = this.num*t.den;
          d = this.den*t.num;
          Rational answer = new Rational(n,d);
          return answer;
     public Rational add(Rational t){

Very simple question about webapp list layout.

Hi Everyone!
I am having a very simple issue. I have created a web app and it has a default list layout looks like:
<table><tbody><tr><td>{tag_counter}. {tag_name}</td></tr></tbody></table>
I have placed web app module (using {module_webapps,14273,a} ) in one of my page. In front-end it has show every thing fine except it shows table tag for each item:
<table>
    <tbody>
        <tr>
            <td>1. <a href="/lot/lot-101">Castlepoint Lot 101</a></td>
        </tr>
    </tbody>
</table>
<table>
    <tbody>
        <tr>
            <td>2. <a href="/lot/efg-lot">EFG Lot</a></td>
        </tr>
    </tbody>
</table>
<table>
    <tbody>
        <tr>
            <td>3. <a href="/lot/some-lot">Some Lot</a></td>
        </tr>
    </tbody>
</table>
<table>
    <tbody>
        <tr>
            <td>4. <a href="/lot/some-other-lot">Some Other Lot</a></td>
        </tr>
    </tbody>
</table>
When I delete table and tbody tags from list view, it stop showing table related tags instead it start showing it without any tag.
How to correct this issue? Please help!!!

Here is what you can do:
-edit the webapp list layout via FTP or via the "alpha" File Manager. The WYSIWYG editor will attempt to "correct" your HTML code. Enter something like this:
<tr>
<td>
{tag_counter}. {tag_name}
</td>
</tr>
-on the page you need the listing placed on enter this code:
<table>
<tbody>
{webappmodule here}
</tbody>
</table>
When the page renders you will get the desired result:
<table>
<tbody>
<tr><td>1</td><td>Item1</td></tr>
<tr><td>2</td><td>Item2</td></tr>
<tr><td>3</td><td>Item3</td></tr>
<tr><td>4</td><td>Item4</td></tr>
</tbody>
</table>

Some simple questions regarding the Xcode.

I have some preliminary questions regarding the Xcode (objective C):
What is the difference between the programming files followed by .h and .m?
What does an asterisk * followed by a text mean (i.e. *window;)?
Is there any source that briefly explains the most common codes with examples (nsstring, nsarray, iboutlet, inaction.....etc)?
Any other tips will be highly appreciated.
Many thanks.

Xcode is the IDE.
Objective-C is the most common language used within Xcode.
UIWindow *window ..... the * means return the address of the instance variable 'window'.
An * is called a pointer to a variable.
Everything you need is explained here: https://developer.apple.com

Pretty simple question regarding headphones.

Hey everybody. I want one of the new shuffles as a secondary iPod, however, I just got a new pair of Bose in-ears and there's no way I'm letting them go to waste. I guess I have a few simple questions anyone who already has a new shuffle can easily answer:
1. Does playback immediately start upon switching the switch to either shuffle or straight through? and
2. Can you plug in the apple headphones, adjust the volume to an acceptable level, select a playlist, etc., then switch out to third party headphones to listen?
As for an adapter, there's no way I'm spending money on accessories for an $80 mp3 player. Sorry Apple...

No
2. Can you plug in the apple headphones, adjust the volume to an acceptable level, select a playlist, etc., then switch out to third party headphones to listen?
Yes
Basically, when you unplug the apple headphones, or even turn it off after you've set what you want it'll keep your 'settings' but stop playing.
When you plug in your own headphones, you just need to switch it off and on again to continue playing where you left off.
Awkward, but possible. Btw, the new shuffle audio quality and playlist handling is definitely an improvement over the 2nd gen shuffle. Basically the player is better all round.
It's just the lack of a headphone adapter that lets it down.

A very simple question (I think)

My school has purchased some mac minis to use in our science lab, and now I want to get some very cheap monitors as we have a limited budget. I have some very basic questions that some experienced users could help me with:
1. Could I use a TV monitor and connect via the HDMI input?
2. What are the drawbacks when connecting a VGA monitor via the HDMI or mini connector?
3. Would spending a bit more and getting a DVI capable monitor connected by the supplied "dongle" be best?
4. What are the best brands of monitor?
Many thanks,
Geoff

Well...
1. If the TV has HDMI input, absolutely. Your main concern is the level of compatibility with a 'computer type' HDMI input, to avoid overscan/underscan issues.
2. You can not connect VGA to HDMI without a device converting the signal from digital to analog, and such would cost much more than its worth. The only way to connect VGA avoiding compatibility issues is via the Mini Displayport with the correct dongle from Apple.
3. I don't see any special advantage to getting a DVI capable computer monitor, over using an HDTV with HDMI or a computer monitor with HDMI. Basically you just need to find whatever display supports the input best as you need, at the best price.
I won't really answer 4 because there's a lot of opinion in that.
