Runtime parse source code
Hi all,
I build small java editor and I have big problem.
Do you know how can I read name or type variable from source code and check variable is local or global .
I found package "com.sun.mirror.declaration" but I don't know how to use interface in this package.
How can I do it?
Sorry,
I mean range of variable in source code. For example:
int b=2;
public a() {
String b="constructor range";
System.out.print(b); // return "constructor range"
I need tools or class which checks range of variable in source code and may return atribut variable.
This tools I want assign to may application writen in Java.
Pleeeease Help.

Parse Timestamp with source code
Somebody help me, how can i convert Date to Timestamp. i want to parse
the Timestamp. but the parse method only return Date.
Please help.
Here are the source code
Date mydate;
String myString;
Timestamp myTime = new Timestamp(mydate.getTime());
myString = DateFormat.getDateTimeInstance().format(myTime);
try {
DateFormat df = DateFormat.getDateTimeInstance(DateFormat.SHORT, DateFormat.SHORT,Locale.US);
myTime = df.parse(myString);
catch (ParseException e) {}
best regards
NauI little chnage your example
String myString;
java.util.Date mydate = new java.util.Date();
Timestamp myTime = new Timestamp(mydate.getTime());
System.out.println("before " + myTime);
myString = DateFormat.getDateTimeInstance(DateFormat.SHORT, DateFormat.FULL, Locale.US).format(myTime);
try {
DateFormat df = DateFormat.getDateTimeInstance(DateFormat.SHORT, DateFormat.FULL, Locale.US);
myTime.setTime(df.parse(myString).getTime());
System.out.println("after " + myTime);
} catch (ParseException e) {
e.printStackTrace();
or yous form
String myString;
java.util.Date mydate = new java.util.Date();
Timestamp myTime = new Timestamp(mydate.getTime());
System.out.println("before " + myTime);
myString = myTime.toString();
myTime = Timestamp.valueOf(myString);
System.out.println("after " + myTime); -
Problem with registering Parser - Recompiled source code, don't see any changes
I had created a parser. I had register this parser with Ifs Manager. I had execute this following statement to see if been registered carefully:
On user ifssys/ifssys
sql)select name,stringvalue,bundle from odmv_property where name= 'p01';
I see my parser....
select name from odmv_propertybundle where id=1139;
ParserLookupByFileExtension
All it's ok. I upload a file with a 'p01' extension with option 'parser' on my Internet Explorer. All work fine.. My parser work. But I need to do some changes in my code. I update my code, recompile my code. My class file have been updated. After my parser (.class) file have been updated I upload a new file with parse option. I don't see any change I do in my code. Why??? How I can update my parser to view change. I have only recompile my code an place my new class files on the same directory. I have try again (change on code, recompile, test) and I don't see any changes.
But I have test by change my classname. My classname before is Test1 and I have rename my classe by Test2. I have compiled this code and a file Test2.class have been generate. I have update my register parser with Ifs Manager to use the new classname Test2. I have chack with sql statement to see if my parser have been updated. I have been updated correctly. I have upload a new file with parse option and I see my change on my code..
Do you have some explanations about that??
How I can update my source code of a parser already registered to the parser take the change I do.
Francois
nullOk, but they have another manner to resolve this problem. If I upload a file with parser option on Windows Nt explorer (Using SmbServer or WcpServer). How I can update the class file into the JVM? I need the restart this those server or just one? If just one which server I need to restart?
Thanks Francois

All the tool does is to instantiate the component and output

Will javafx runtime source code be open?
I wonder if oracle will share the source code of javafx, especially controls. I dont say open source javafx, that is a separate topic. Source code of controls will increase the speed of developing javafx projects.
Why?
All it does is read in some data (a list of example projects), and displays it in a Tree. Each project points to a path containing the application build files that are displayed in an iframe (web version), or an HTML control of some sorts for AIR.
All the worthwhile functionality is sitting in each individual project, most of which (if not all) have browsable source. -
Xletview: why not use sun's javaTV source code directly ?
xletview : one emulator for viewing MHP Xlets on a PC;
I see many difference from sun's code about the part of javaTV.
Why the author Martin Sveden need to rewrite them and not use sun's javaTV source code directly ?
Thank you for your any answer.
Sorry for my horrible english.XleView is a fine effort, but it has its limitations. I tried using it for the GunBunny demo available in the JavaME SDK 3.0 Eary Access available in
http://java.sun.com/javame/downloads/sdk30ea.jsp
and I encountered some of thost limitations. What Sveden does it several tricky manipulations in a classloader for the Xlet. In particular, he translates bytecode as he loads the Xlet's classes, changing some class names, such as changing
java.awt.Toolkit
tto
xjava.awt.Toolkit
This works up to a point. This version of Toolkit usually just turns around calls java.awt.Toolkit's corresponding routine, but he deliberately he does not implement the ubiquitous
public Image createImage(URL url)
When I downloaded his source and tried adding ths into his code, I then encountered at runtime
Uncaught error fetching image:
java.lang.NullPointerException
at sun.awt.image.URLImageSource.getConnection(URLImageSource.java:97)
at sun.awt.image.URLImageSource.getDecoder(URLImageSource.java:107)
at sun.awt.image.InputStreamImageSource.doFetch(InputStreamImageSource.java:240)
at sun.awt.image.ImageFetcher.fetchloop(ImageFetcher.java:172)
at sun.awt.image.ImageFetcher.run(ImageFetcher.java:136)
I think that this is some optimization within J2SE where they do not wait for the image to load and do the fetching in a separate thread. I do not know if there is some way to force the Sun's JVM to disable this optimization and I have not investigated furher, but I did email Svenden. I noticed that the current version of XleTView is 0.3.6 which is dated June 2004 and the web site http://www.xletview.org/ has had not news since 2005 .
I note that Svenden provides an elegant user interface but I advise you not try to learn the API's from his classes: he makes no effort to keep his implementation separate from the API standards so, for instance, his version of HScene is
package org.havi.ui;
public class HScene extends Container
implements HComponentOrdering, ImageObserver, MenuContainer, Serializable {
whereas the real standard is
public class HScene extends Container
implements HComponentOrdering {
I hate to critize such a fine effort, but it is best to keep an imlementation separate from the public API.
I agree that having a lightweight, simple and Java feature-complete Xlet viewer running would be very helpful, especially if BD-J gains much popularity. I have found trying to work with the vendor players described at
http://wiki.java.net/bin/view/Mobileandembedded/Blu-RayDiscHelloWorld
to be frustrating. I tried all four mentioned and I have gotten none of them to work for me yet. These are huge downloads and the "Intro Version" of Arcsoft pointed to at the SDK 3.0 Early Access page
http://www.arcsoft.com/products/totalmediatheatre/
just gives a "File not found" HTML page. This forum post mentions that perhaps it was recently taken down?
http://www.arcsoft.com/forum/forum_posts.asp?TID=1084
I have already emailed Michael Downs of Arcsoft since he is mentioned here:
http://wiki.java.net/bin/view/Mobileandembedded/BDJPCPlayers
What did work for me was to take Sun's JavaTV 1.1 Reference Implementation and PowerDVD's BDJ.jar and hack/fix a few classes to get GunBunny to work within the RI's RunXlet program. This is not trivial but I will will describe:
Download the JavaME 3.0 SDK EA and then download the correct version of PowerDVD that the SDK page points to:
http://www.brothersoft.com/powerdvd-download-50794.html
Download the RI binary and source of Java TV API 1.1
http://java.sun.com/javame/technology/javatv/index.jsp
Since I am too lazy to use anything but the latest 1.6 JRE as a runtime, I have to fix
com.sun.tv.media.util.MediaThread
to comment out its stop() method. This is becase stop() was deprecated and made final in J2SE 1.5
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Thread.html#stop()
http://java.sun.com/j2se/1.5.0/docs/guide/misc/threadPrimitiveDeprecation.html
Next, I had to mae a change to Sun's JavaTV implementation to keep the GunBunny demo happy by providing a ServiceContext. The RunXlet program calls SIEmulator, but that environment does not provide a ServiceContex, so I added one back in:
com.sun.tv.receiver.SIEmulator
private static ServiceContext svcctx = null;
Add before every call to new AppSignalEvent() and add the svcctx as the second-to-last argument:
if(svcctx == null){ try { svcctx = new com.sun.tv.ServiceContextImpl(); }catch (Exception e){ e.printStackTrace(); } }
I then had to hack a few PowerDVD classes, which is evil of me. First, I had to build an empty class by the name of
sun.util.BDJPlugin
becuase some PowerDVD class extends it but it is not in its BDJ.jar and then I had to reverse-compile (evil!) and modify one of their internal classes to avoid a dependency on their native methods. What I ended up with was a hacked version of com.cl.bdj.helper.CUtil to avoid the native methods which access the registry where they query for registry settings but also provide a default value (which I return).
com.cl.bdj.helper.CUtil
private static String pGetRegistryString(long i ,String string ,String string3) {
return string3;
private static int pGetRegistryInt(long i ,String string ,int j) {
return j;
The last thing I had to do was to change com.hdccookbook.gunbunny.BaseXlet, to use the JavaTV container rather than the org.havi one:
import javax.tv.graphics.TVContainer;
import java.awt.Container;
change
// protected HScene scene;
protected Container scene;
public final void run() {
// waitForPresenting();
// scene = HSceneFactory.getInstance().getDefaultHScene();
scene = TVContainer.getRootContainer(xletContext);
In order to having working keys, I had to add the KeyListener interface to BaseXet and
run(){
addKeyListener(this);
and then add a near duplicate of the org.dvb.event.UserEvent* stuff that is already there:
public void keyPressed(KeyEvent e){
switch(e.getKeyCode()){
case KeyEvent.VK_0:
case KeyEvent.VK_1:
case KeyEvent.VK_2:
case KeyEvent.VK_3:
case KeyEvent.VK_4:
case KeyEvent.VK_5:
case KeyEvent.VK_6:
case KeyEvent.VK_7:
case KeyEvent.VK_8:
case KeyEvent.VK_9:
numberKeyPressed(e.getKeyCode() - KeyEvent.VK_0);
break;
case KeyEvent.VK_ENTER:
enterKeyPressed();
break;
case KeyEvent.VK_LEFT:
arrowLeftKeyPressed();
break;
case KeyEvent.VK_RIGHT:
arrowRightPressed();
break;
case KeyEvent.VK_UP:
arrowUpPressed();
break;
case KeyEvent.VK_DOWN:
arrowDownPressed();
break;
public void keyReleased(KeyEvent e){
// System.out.println("Released: e="+e+" code="+e.getKeyCode());
public void keyTyped(KeyEvent e) {
// System.out.println("Typed: e="+e+" code="+e.getKeyCode());
It then comes up and functions, but the rendering is not very good. Again, this is complete hack. Running the Java TV 1.1 RI in a JRE 1.6 is not supported. If you try to run any of the other examples, you will discover that the XML parsing is broken in JRE 1.6 with this message:
Parsing failed: com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequence
Exception: Invalid byte 1 of 1-byte UTF-8 sequence., file: lib\JavaTVSampleFile01.xml
and you have to go and change the lines in
lib\JavaTV.properties
from
ServiceFileHandler=com.sun.tv.receiver.ReceiverFile
# ServiceFileHandler=SampleData_01
to
# ServiceFileHandler=com.sun.tv.receiver.ReceiverFile
ServiceFileHandler=SampleData_01
and build samples\db\SampleData_01.java and put it in your classpath along with all these other hacks.
Nonetheless, if you want to develop a somewhat generic Xlet that uses some BD-J features, that is how you might do it. But the moment you exercise anything else in the vendor's BDJ.jar that simply doe snot work outside of their environment or invokes one of their native methods, you are again stuck.
It would be nice if Sun would at least bother to update the JavaTV RI with the fixes I hae mentioned. Their "jmflite" implementation does not render perfecly but at least it would give the programmer something to work with without having to deal with an older JRE, etc.

I want to thank you for responding to the thread I started on the forum at java.sun.com. Your solution to my problem of needing to print the code of the html pages that the file I included generates was just what I was looking for. However, I have some further questions to ask, if you don't mind. To clarify my task I should say that your rephrasing of the problem is accurate: "You wan't to display the contents of the HTML file that the web server produces in response of client's request?"
Yes, this is what I need to do, but also it needs to display the source code of that html file that the server produces in response to the client's request. Also, in this case, I am the client requesting that the server return some html file, and I'm not sure where the server is. But the webserver.java file that I shared on the forum is on my local machine. I was wondering if I could modify this webserver.java file at my home so that any html file the server returns to me would automatically display the source code. This is a school project of mine and I am stuck on this one thing here.
Further, where would I put the "foo.html" file so it can be written to?
FileOuputStream fos = new FileOutputStream("foo.html");
fos.write(bytes);
fos.close();
Thanks so much for your help. I look forward to your response, at your convenience.

If I Use JavaFX to Create a Game Do I Have to Release the Source Code?
Hello,
I've asked this question before, but I just thought I would try it again now
that version 1.0 is out.
If I Use JavaFX to Create a Game Do I Have to Release the Source Code?
Thanx in advance.Could you please point me to a resource describing "the JavaFX Runtime license"? I'm trying to find answers to the following questions:
1. I'd like to use Scenario.jar from the JavaFX project in a desktop app that is not using Webstart and is not an applet. Will I be able to ship the jar with my software?
2. Can JavaFX applications be distributed as commercial software in the absence of a Web connection?
What's not clear to me is which is the real license for Scenario.jar (as shipped with JavaFX). Is it the one in openjfx-compiler's trunk, or the one that comes with the JavaFX SDK (which is very vague about redistribution)? -
Generated XML doc file contains comments from MFC source code
Hello, in my project I use the option /doc to generate XML doc file from my source codes but unfortunately in the output XML file there are mixed also comments from original MFC source codes, see the part of generated xml file:
Is there a solution to ignore these MFC cpp files?
Many thanks

Thank you for posting in MSDN forum.
>>In my project I use the option /doc to generate XML doc file from my source codes but unfortunately in the output XML file there are mixed also comments from original MFC source codes.
Based on your issue, could you please tell me how you use the option /doc to generate XML doc file from your source codes?
If you use the option /doc to generate the XML doc file by right-click the your MFC project->Properties->Configuration Properties->C/C++->Output file->set the Generate XML document files as Yes(/doc) like the following screen shot.
(1)If yes, since we could not reproduce your issue in mu side, so if possible, I suggest you could share me your MFC project so that we will further help you support this issue.
You could upload your MFC project to the OneDrive and then copy link here.
(2)If no, please try the above way to generate XML doc file and then check if you still get same issue.

Java.lang.RuntimeException: Uncompilable source code - missing method body
Hi,
I am getting the following error at runtime
java.lang.RuntimeException: Uncompilable source code - missing method body, or declare abstractwhen I try to instantiate a class using reflexion as following:
MyInstance = MyClass.newInstance(); I have tried to find some explanation using Google, but could not find any that fit my case. MyClass's implementation has a public constructor with no parameter. There is no error at compile time when cleaning and building all code.
Anyone has tips about what could cause this error?
Thanks.Jrm wrote:

How to dynamically configure JPA setting at runtime using java code?
Hi,
I am new to EJB 3.0 and JPA. I am trying to help my company to deploy the use of JPA in EJB3.0. Currently, i am trying out with OpenJPA in IBM Webshpere Application Server 7.0. We have four different WAS servers running for testing, system integration testing, user testing and production respectively, and in each region, the configurations for data source, JDBC username and password, schema, etc are different. So i think i would need to configure the JPA setting during runtime using Java code that determines which is the environment. And apparently i am stuck with the limited knowledge i have.
1) I understand that i could override the JDBC in the persistence xml by creating entity manager using entity manager factory. But is it possible that i do similar thing by using inejction of persistence context on entity manager to obtain a container managed entity manager?
2) Alternatively, it is possible to create multiple persistence unit in the XML and inject different PU to the entity manager, am i right? But how to inject dynamically since @PersistenceContext(unitName="xxx") only accepts constant declaration.
3) Is it possible that the JDBC username and password are read from properties file?
Thanks for your help in advance!Hi
Thanks for the reply.
Are you saying that i have to configure the data source authentication to the backend DB2 using the JAAS-J2C? Correct me if i am mistaken. I guess i am unable to do so as the application server setup only contains one data source, and the server hosted a number of applications. Every applications has their own JDBC username and password supply to the data source (the ID supplied at the DB2 side will decide which resource can access) and thus, i have to supply the username and password at runtime. Talked to the server guy and seems that it is not feasible to have seperate datasource for each applications as considered to the volume of applications hosted inside the server.
Any suggestion?
