About control flow graph on java

i want to ask if there are some papers about control flow graph based on java or another object oriented language.
thanks

> i have search already on google. the problem is that i
didnt find anything usefull on this.
Once again, we have no idea what may or may not be useful to you or why the Google search results don't meet your satisfaction.
> i have to do a research on this subject.
Okay.
so i asked if u have already
found some papers about control flow graph based on
java or with some other object oriented language.
And the answer is, "Yes, I have found many". I found them easily with Google. Again, I have no idea which ones may or may not be useful to you, so it doesn't make much sense to just start posting a bunch of links only to have you say, "Nope, that's not what I'm looking for".
Keep researching, and best of luck.

About: control USB device with Java

Any body know how to control USB device with Java?
Does JDK provide a package for USB?
Is there any web site concerning USB programming?
Thank you! ^_^

Look at www.prosyst.com. There is an usb bundle (linux

Programatically calling control flows from java code

Hi all,
I have a bounded taskFlow that uses pageFragments. This flow is a region in a page(.jspx).
In my page fragment, I have a inputComboboxListOfValues with a ValueChangeListener code in a java bean.
I want when a value is changed, to programatically call "controll flow" (this one has: "From Activity Id" -the page fragment with that inputComboboxListOfValues, and "To Activity Id" - the default Activity on this task Flow).
So when the value change, practically I want to restart the flow programatically and pass the selected value as input parameter.
Since the inputComboboxListOfValues is not like a button where in the "Action" property you can set the Control Flow and navigate somewhere, the only option I have is to programatically cause navigation from java code (example: the value change listener code).
Can this be achieved?
Any advice is helpfull.

Hi,
Absolutely, you can do it using the NavigationHandler. Try the following in you value change listener:
FacesContext context = FacesContext.getcurrentInstance();
NavigationHandler handler = context.getApplication().getNavigationHandler();
handler.handleNavigation(context, null, outcome);
// Render the response after that phase, the button actions should not be called
context.renderResponse();
// Add the following line if you want to prevent further value change listeners to be called
// throw new AbortProcessingException();Regards,

Bounded-Task-Flow Page Fragment Control Flow Help

jDeveloper: 11.1.1.0.2
I am having an issue trying to figure out the correct way to use control flow cases between a bounded-task-flow with page fragments and an unbounded-task-flow page. We have taken the approach in our application to have a few shell / container pages to host bounded-task-flows made up of page fragments to facilitate re-usability and to speed up development. There are 4 or 5 shell pages on the applications unbounded-task-flow. As of now, we have about 20 page fragments that are implemented as bounded-task-flows. These fragments don't do much now, meaning there is only a single fragment in each bounded-task-flow. The issue I am having is trying to invoke a control flow navigation action from one of the fragments to load a different shell page.
For Example, shellPage1.jspx contains fragment-flow-1 as a region. In my adfc-config.xml I have shellPage1.jspx and shellPage2.jspx, with control flow cases "toShell1" and "toShell2" respectively connecting the two pages. I have a link's action bound to the "toShell2" within the fragment that makes up fragment-flow-1. When the application is run, shellPage1.jspx and its fragment are displayed. But clicking on the link in the fragment ("toShell2") does absolutely nothing. It does not navigate me to the shellPage2.jspx as expected. What am I doing wrong here or do not understand?
If the fragment is included as a JSP include, and not a bounded task flow include, everything works as expected. This is not desirable as we then need to copy the fragment's pageDef into the shellPage's pageDef to get the DataControls to function.
If the faces-config.xml is used instead, and a JSF navigation case is used, it will also work as expected. This is not desirable because we really don't want to be mixing adcf-config and faces-config.
So I am really stumped here.... Thanks in advance!

Hi there:
In your case, the adfc-config.xml has the control flow case between shell pages. And the task-flow-N.xml or your-task-flow.xml for each page fragment by default doesn't inherit control flow case from their containing shell page. In your case, in the page fragment task-flow.xml, you should add a "Parent Action" to flow to shell page2 for example. The outcome of "Parent Action" would be "toShell2" if calling from ShellPage1 page fragment.
Is this 'Correct' or 'Helpful' for you? Please mark it as so if it does.
Good luck,
Alex

Cannot build a flow graph with the customized options

we implemented a DataSource for video capturing that is based on the lti-civil API, so that video capturing on Mac OS X should be possible.

We guess that the problem was first the wrong input format (wrong video-size or wrong framerate) but this has been changed to the correct format.
The flow graph looks like correct, but it doesn't work anyway.
What does the last line in the log means, and are there any information were the problem good be located?

How were you even able to accomplish that? In my classpath I have fmj-nojmf.jar, jmf.jar and lti-civil.jar but I keep on getting this in my log.

How to draw a directed 2D graph in java

how to draw a directed 2D graph in java?-if anybody can suggest some tutorials about this topic or can suggest the way to draw the graph.......how can i do that.......if the nodes of the graph has X and Y co-ordinate.........and the neighbours of each node are known.......suppose
node1 has neighboures node2,node3 and node4.....node2 has node5 and node3 as neighbours.....in this way....so directed edge from node1 to node2,node3,and node4......
or if u can suggest other way out......plz reply....

Tutorial on AWT/Swing control flow

Greetings all,
Just wondering if any of you folks know of a good tutorial on AWT/Swing control flow? I'm doing some pretty complex stuff with a table whose editors call other windows and insert values into the table based on callback objects...weird stuff happening with loss of focus when the other windows come out, etc etc etc.
I have it working via a series of what I consider kludges, but I would really like to implement it cleanly, and it's looking like that's going to require understanding <ugh> <grin>
So it looks like it's time that I bit the bullet and got to grips with control flow in AWT/Swing. Is there a tutorial out there that could help me with this?
Many TIA

Let's take your word for it, but if you have the slightest doubt please consider the subject: EDT violation is a classic here.OK sure, but I really don't think I'm violating it. I avoid multi-threading like the plague, and only introduced it for my report writer because I wanted to have a little window advising the user that the report was in the process of being written.Raise your left hand and swear this report writer is not running when you experience the problem you describe! >o(
OK, this is just kidding, as per the rest of your description, it sounds reasonable now to assume that your problem is not related to EDT violation.
I'm doing some pretty complex stuff with a table whose editors call other windows and insert values into the table based on callback objects...This summary is a bit worrying, and I thought you would mention problems in the display of the table being edited. But you seem to refer to problems in other windows, or did I misunderstand?
Or do you mean, loss of focus in the editor still being edited? Can you please clarify what you do and what your problems are?
In particular, what does the other windows come out mean?OK, I was trying to be sparse with details because I didn't think they were relevant.Actually the worrying seems all the more justified, now that you have described it more extensively: I was afraid that you would raise other windows while editing, and that's the case. I know little of focus though...
I have a table in window A, one of whose columns has a custom editor which, when a cell in the column is double-clicked, registers itself with window B as a choice-listener (see later) then asks window B to come to the front. Window B, when the user performs a choice amongst the UI elements in there, fires a choice-event to its listener, i.e. the custom editor. At which point the editor saves away the chosen value (for use by getCellEditorValue()), sets the text in the cell appropriately, turns edit mode off via fireEditStopped(), and brings window A back to the front.
(...) once the custom editor asks window B to come to the front, the table in window A loses focus and when it is brought back to the front, the table's JScrollPane seems to have the focus (visually, it has the focus rectangle around it). Pressing the Tab key has no effect on focus; you have to use the mouse to focus something.I assume you have read the tutorial on using tables in Swing.
It contains an example where a custom editor is bringing up a dialog: http://download.oracle.com/javase/tutorial/uiswing/components/table.html#editor
AFAIK, the example does not suffer from focus problems.
What I am finding, and I reiterate this is new since I rewrote the windowing subsystem for the app (the custom editor was not changed in the rewrite), is that (...)Just what do you call "rewriting the windowing system" (just to rule out the possibility of something Ramboesque)?
I have no idea why this loss of focus is occurring, and I am at a loss to begin to figure it out. As I wrote above, I have a series of kludges which gets around the symptoms, but I would really rather figure it out and fix it.OK I admit I cannot tell what happens exactly, but:
1) instead of bringing window B to front, couldn't the editor bring up a dialog B (e.g. using JOptionPane.showXxxDialog() to bring up just the choice panel? The advantage is that it is more "synchronous", you can control when the window A's table model is updated.
2) what worries me too is that you update the model of the table being edited while you're editing one cell of it? Would it be possible, and make sense in your case, to update this model later (that is, post the model update as an invokeLater(...) call)? I don't see how seeing the table updating underneath helps the user editing its cell, but you may have your reasons.
What do you call flow control , or control flow in AWT/Swing?Basically, what I am after is something that will help me begin to understand/diagnose problems such as the above when they happen in my code. I am deeply averse to multi-threading (...) Things in my code were working, and that was enough for me.
But the above behaviour, and another weird behaviour I was having last week, which again I have solved with what I consider a kludge, and again which only began with my new windowing subsystem, have caused me to realise that it's time I really got to grips with this issue.Yes, when they say beware of threads when using Swing , nobody tells to not use threads! Just to be aware of how special Swing is with regards to threads (at least, compared to AWT, that didn't make such warning).
I would like, for example, to really deep-down understand exactly when listeners for AWT-Swing events get called. I don't really care so much when the events get put on the queue, but I do care when exactly my event handlers will be called. This will help me diagnose problems, I'm sure.Well they get called in the EDT, by some framework code that, in an infinite loop, does something along the lines of:
- pop next event from the event queue
- determine which is the target widget
- let the widget transform the event and send it to all registered listeners
Now with dialogs, things gets dimmer, because while a dialog is brought up (via a<tt>setVisible(true)</TT> call on the EDT, the EDT is indeed suspended, and a new event thread manages the events for the dialog).
I'm sorry I have no reference for that behavior, and my description is certainly blurry (and possibly wrong), but I don't think your problem is so much related to threading as I initially thought.
N.B.: Darryl's second link does features sequence diagrams that try to demonstrate what happen (in a specific example with asynchronous access, but you can derive the simpler, regular, working, from it).OK, yes I saw that diagram, I was offput by the asynchronicity but I will have another look tomorrow also. Thanks againDon't put too much hopes in there, indeed it's definitely not the kind of info I understand you're looking after.
Much luck all the same, and feel free to come back with your findings, or with more questions, about the initial subject (reference on event flow) and the specific problem (your focus issues with the editor).
I also cannot end this message without suggesting that you try to reproduce the problem with an SSCCE (http://sscce.org), that you could post here for us to try out. See this recent discussion about the multiple interests of this approach: {message:id=9587964}

Control flow extraction

I am looking for a package that gives me the control flow of a given java program. I need this information so that I can do some static analysis on the control flow.
Can anyone recommend anything?
Thanks

Barat (http://pmd.sourceforge.net) provides a very nice object view of Java source (control structures and all). The distribution is very untidy and it relies on the "Poor Man's Genericity" package. It is a pain to use but I like it a lot. Not much of a community behind it.
PMD (http://sourceforge.net/projects/barat) seems to be a very solid and polished static analysis framework. I haven't used it much. If I remember correctly it gives you an abstract-tree view of the source rather than a coupled object model of it.
Then again you can roll your own. Both these projects rely on JavaCC/JJTree combo (https://javacc.dev.java.net) to build a syntax tree.

Dialog control flow case not opening in new browser window

Hello -
Using JDev 11gR1.
I have a page fragment that contains a table of command links like so:
        <af:commandLink text="#{row.id}" id="cl2"
                        action="#{reportRunnerBean.runReportAction}"
                        useWindow="true" windowHeight="500" windowWidth="500">
          <f:param value="#{row.id}" name="reportId" id="p2"/>
        </af:commandLink>the runReportAction method returns the String: "dialog:runReport"
in my page flow, the page fragment has a control flow case with the outcome "dialog:runReport" that leads to a URL View with the URL setting set to #{pageFlowScope.reportUrl}
(the reportRunAction places a string in page flow scope with the key of "reportUrl". in case it matters, the url is external to the application)
When I click on the link, I am directed to the correct URL. However, it does not open in a new browser window - it takes up the main browser window.
Is there something obvious that I am doing wrong?
Thank you for reading this,
-- Scott

Well, I couldn't figure out why the dialog wasn't working correctly, so I changed my page to use a server listener to handle the logic I wanted and just used af:goLink instead of a command link. That command link above became:
          <af:goLink text="#{row.id}" id="gl1"
                     destination="#{row.reportUrl}"
                     targetFrame="_blank">
            <af:clientAttribute name="reportId" value="#{row.id}"/>
            <af:clientListener method="logReport" type="click"/>
            <af:serverListener type="LogReportEvent"
                               method="#{reportListBean.logReportInvocation}"/>
          </af:goLink>with the following client listener:
    <af:resource type="javascript">
      function logReport(evt) {
          var component = evt.getSource();
          var reportIdParam = component.getProperty("reportId");
          AdfCustomEvent.queue(component,
                               "LogReportEvent",
                               { reportId: reportIdParam}, false);
    </af:resource>and code in the bean:
    public void logReportInvocation(ClientEvent clientEvent) {
            String reportId =
                (String)clientEvent.getParameters().get("reportId");
            //...do something w/reportId here...
    }Thanks to anyone who took the time to read this.
