Is there a recommended way to upgrade Quartz in JBoss 4.2.x? JBoss bundles quartz 1.5.2, but I have encountered issues (QUARTZ-399, QUARTZ-520) that I want to avoid. I would not want to patch quartz.jar in JBoss just to resolve the errors, but instead provide a new quartz.jar (plus associated configuration artifacts). The Quartz 1.6 mi...
Hi, I am running a series of JUnits using Apache ANT using JDK 1.5. All JUnits that use an Oracle JDBC driver give the UnsatisfiedLinkError shown below. What native library is it looking for and how do I solve this? What should the PATH variable contain? oracle/jdbc/driver/T2CConnection.t2cGetCharSet([CI[CI[CI[CII[SLoracle/jdbc/drive...

Now, I have an object of type A and want to do the following: If...
I'm in college. Basically I have already learnt the syntax of java from books and have been programming in java for two years (Not every other day of course, because it's a computer science and not software engineering course). However, I find myself lacking sufficient knowledge of java and feel inadequate. For example, none of the book...
We have a number of projects that use the same and/or similar package names. Many or these projects will build jar files that are used by other projects. We have found a number of foo.util foo.db and foo.exceptions where the same class names are being used leading to name space conflicts. Does anyone know of a tool that will search a s...
I want completely automated integration testing for a Maven project. The integration tests require that an external (platform-dependent) program is started before running. Ideally, the external program would be killed after the unit tests are finished, but is not necessary. Is there a Maven plugin to accomplish this? Other ideas? ...
It appears that our implementation of using Quartz - JDBCJobStore along with Spring, Hibernate and Websphere is throwing unmanaged threads. I have done some reading and found a tech article from IBM stating that the usage of Quartz with Spring will cause that. They make the suggestion of using CommnonJ to address this issue. I have ...

Is there a way to use a Graphics object's 'setClip()' method to clip using a Line-ish shape? Right now I'm trying to use a Polygon shape but I'm having problems simulating the "width" of the line. I basically draw the line, and when I reach the end, I redraw it but this time subtract the line width from y-coordinate: Polygon poly = ne...
Does anyone know of a way, in Java, to convert an earth surface position from lat, lon to UTM (say in WGS84)? I'm currently looking at Geotools but unfortunately the solution is not obvious. ...
I'm working with a combobox in a Swing-based application, and I'm having a hard time figuring out what to do to differentiate between an ItemEvent that is generated from a user event vs one caused by the application. For instance, Lets say I have a combobox, 'combo' and I'm listening for itemStateChanged events with my ItemListener, 'l...

Is it possible to suppress warnings in Eclipse for JDK1.4 project? EDIT: Longer version. There is a project which requires JDK1.4 (no annotations). Only way of suppressing warnings I know is using annotation @SuppressWarnings - no can do in JDK1.4. Is there any way to remove some warning notifications in some specific method/class (not ...

Why do I get compiler errors with this Java code? 1 public List<? extends Foo> getFoos() 2 { 3 List<? extends Foo> foos = new ArrayList<? extends Foo>(); 4 foos.add(new SubFoo()); 5 return foos; 6 } Where 'SubFoo' is a concrete class that implements Foo, and Foo is an interface. Errors I get with this code: On Line 3: "C...
I need to enumerate all classes in a package and add them to a List. The non-dynamic version for a single class goes like this: List allClasses = new ArrayList(); allClasses.add(String.class); How can I do this dynamically to add all classes in a package and all its subpackages? Update: Having read the early answers, it's absolutel...
Given an aggregation of class instances which refer to each other in a complex, circular, fashion: is it possible that the garbage collector may not be able to free these objects? I vaguely recall this being an issue in the JVM in the past, but I thought this was resolved years ago. yet, some investigation in jhat has revealed a circul...
