I have a multi module maven project, which builds successfully, I'd like to build just one of the modules I have. How would I do that with profiles ? I could do it from console in two ways, one way is go to the child module and mvn package or I could use reactor to build just one module.
Can I do the same thing with profiles? By modifying POM? Thank you
EDIT
If is impossible from POM, can I do it from settings.xml ?

Guys,
I"m trying to use Tyburn to do some BDD with JBehave and I've got a question about what Tyburn can do. Can Tyburn simulate Menu selections? Like Ive I want to say something like
@Then("when I select 'Start' from the Recording Menu)
selectMenu(Recording)
selectMenuItem(Start)
Is there a way to make this happen?
Thanks,
Joe
Basically I'm trying to make a little app for watching offline content. So there's a moment where the user selects to download the contents (and the app should download about 300 small files and images).
I'd like to show the user how does the process go if he enters the proper activity. Showing a list of all the files, telling what has been already downloaded, in progress or waiting for download.
My problem is that I really don't know what approach to take for achieve this. Since the download should last until finished I imagine the solution is an Service, but whats best? an IntentService, a Bound Service or an Standard Service calling a startService() for each download? And how can I keep my objects updated for displaying them later? should I use a database or objects in memory?
Thanks
Hi there,
I'm trying to load a custom font as follows:
private Paint customFont18;
customFont18 = new Paint();
customFont18.setTextSize(18);
Typeface fontFace = Typeface.createFromAsset(getAssets(), "FONT.TTF");
customFont18.setTypeface(fontFace);
The getAssets fails, thows this:
-The method getAssets() is undefined for the type MyClass
-assetManager cannot be resolved to a variable
What is my problem? I've seen several examples like this but none works in my case.
Thanks in advance.
I jsut learned that
A class may be declared with the
modifier public, in which case that
class is visible to all classes
everywhere. If a class has no modifier
(the default, also known as
package-private), it is visible only
within its own package.
This is a clear statement. But this information interfere with my understanding of importing of packages (which easily can be wrong). I thought that importing a package I make classes from the imported package visible to the importing class.
So, how does it work? Are public classes visible to all classes everywhere under condition that the package containing the public class is imported? Or there is not such a condition? What about the package-private classes? They are invisible no mater if the containing package was imported or not?
ADDED:
It seems to me that I got 2 answers which are marked as good (up-voted) and which contradict eachother.
Hi,
I want to write a buil.xml file that should open a new terminal for every client/server i want to use for testings.
How can i do that? i tried this code to run for example the 'ls' command on the newly created terminal. He created the terminal but doesn't run the cmd.
thanks.
I have tried to write an Android application with an activity that should be launched from a different application. It is not a content provider, just an app with a gui that should not be listed among the installed applications. I have tried the code examples here and it seems to be quite easy to launch existing providers and so on, but I fail to figure out how to just write a "hidden" app and launch it from a different one.
The basic use case is:
App A is a normal apk launchable from the application list.
App B is a different apk with known package and activity names, but is is not visible or launchable from the application list.
App A launches app B using the package and class names (or perhaps a URI constructed from these?).
I fail in the third step. Is it possible to do this?
A colleague of mine sets reference to null in finally blocks. I think this is nonsense.
public Something getSomething() {
JDBCConnection jdbc=null;
try {
jdbc=JDBCManager.getConnection(JDBCTypes.MYSQL);
}
finally {
JDBCManager.free(jdbc);
jdbc=null; // <-- Useful or not?
}
}
What do you think of it?
I'm working on a Serpinski triangle program that asks the user for the levels of triangles to draw. In the interests of idiot-proofing my program, I put this in:
Scanner input= new Scanner(System.in);
System.out.println(msg);
try {
level= input.nextInt();
} catch (Exception e) {
System.out.print(warning);
//restart main method
}
Is it possible, if the user punches in a letter or symbol, to restart the main method after the exception has been caught?
I have this weird issue,when I use
> File FileToRead = new File("\\\\MYSERVER\\MYFOLDER\\MYFOLDER\\MYPICTURE.JPG");
to read a file over a network,all I get is a null pointer exception.Normally a local path works with this,but when on a network path,I just couldn't manage to get it to work.Any ideas?
PS:oh and my network connection seems to work,no issues when accessing data in windows explorer...
More of the code:
File FileToRead = new File("file://DOKSERVICE/Somefolder/ProductImage/01001.JPG");
// File FileToRead = new File("c:\\dog.jpg"); local test
BufferedImage image = ImageIO.read(FileToRead);
BufferedImage resizedimage = new BufferedImage(260, 260,BufferedImage.TYPE_INT_RGB );
Graphics2D g = resizedimage.createGraphics();
g.drawImage(image, 0, 0, 260, 260, null);
g.dispose();
picture.setIcon(new ImageIcon(image));
I am in the midst of changing my JPA code around to make use of threads. I have a separate entity manager and transaction for each thread.
What I used to have (for the single threaded environment) was code like:
// get object from the entity manager
X x = getObjectX(jpaQuery);
if(x == null)
{
x = new X();
x.setVariable(foo);
entityManager.persist(x);
}
With that code in the multi threaded environment I am getting duplicate keys since, I assume, getObjectX returns null for a thread, then that thread is swapped out, the next thread calls getObjextX, also getting null, and then both threads will create and persist a new X().
Short of adding in synchronization, is there an atomic way to get/save-if-doesn't-exist a value with JPA or should I rethink my approach
EDIT:
I am using the latest Eclipselink and MySql 5.1
This might be a stupid question, but I just saw a question asking how to create a Type variable for a generic type. The consensus seemed to be that you should have a dummy method returning that type, and then use reflection to get it (in this case he wanted Map<String, String>). Something like this :
public Map<String, String> dummy() { throw new Error(); }
Type mapStringString = Class.forName("ThisClass").getMethod("dummy").getGenericReturnType();
My question is, not having used reflection that much, couldn't you just do something like:
Type mapStringString = new ParameterizedType() {
public Type getRawType() {
return Map.class;
}
public Type getOwnerType() {
return null;
}
public Type[] getActualTypeArguments() {
return new Type[] { String.class, String.class };
}
};
Would this work? If not, why not? And what are some of the dangers/problems if it does (besides being able to return some Type like Integer<String> which is obviously not possible.
I'm working on a data mining research project and use code from a big svn.
Apparently one of the methods I use from that svn uses randomness somewhere without asking for a seed, which makes 2 calls to my program return different results. That's annoying for what I want to do, so I'm trying to locate that "uncontrolled" randomness.
Since the classes I use depend on many other, that's pretty painful to do by hand. Any idea how I could find where that randomness comes from ?
Say a month end date is the date in a month which is the last non-weekend and non-holiday day in that month. How can I find the most recent past month end date with Joda time? For example, the answer for today would be Friday 28th May because that was May's month end and May was the most recent month to end.
I am looking for a way to direct all the jetty 7 logging to syslog. My current configuration
dumps everything to JETTY_HOME/logs/.. After some initial ivestigation, it seems I should change JETTY_HOME/etc/jetty-logging.xml, but this does not look straightforward. It looks like I should create a new PrintStream implementation which sends its output to syslog and redirecting stderr and stdout to that class in jetty-logging.xml.
any easier way to do that or to make jetty log directly to log4j ?
Thanks
I have a Person entity mapped by Hibernate to a database table in a database catalog "Active". After a period of time, records in this database table in the "Active" catalog are archived/moved to an exact copy of the table in a database Catalog "History". I have the need to retrieve from both the Active and History Catalogs. Is there a better way to model this with Hibernate annotations than making an abstract class that 2 classes extend from.
This is what I have now.
@MappedSuperclass
public abstract class Person {
@Id
private Integer id;
private String name;
}
@Entity
@Table(name="Person", catalog="Active")
public class PersonActive extends Person {
}
@Entity
@Table(name="Person", catalog="History")
public class PersonHistory extends Person {
}
If I have 6 modules in my project is it possible to build only one out of six ? without commenting out others ?
