We have a (non-web app) Spring application that throws a NoSuchBeanDefinitionException when running tests on our CruiseControl continuous integration linux box. The test runs fine on Windows in Eclipse. The exception is thrown on the getBean() method: ApplicationContext context = new ClassPathXmlApplicationContext(CONTEXT_FILE); MyBea...

I have a test for a create DB method and I need a temp directory to put it in. The directory will be removed after the test is done. I tried using File.createTempFile(), like so: tempDir = File.createTempFile("install", "dir"); tempDir.mkdir(); But tempDir is already exists as a file. How do I create a temp directory as opposed to a f...
@Column(name="DateOfBirth") private Date dateOfBirth; I specifically need the above code to create a column named "DateOfBirth," instead Hibernate gives me a column named date_of_birth. How can I change this? Is there a web.xml property? I came across DefaultNamingStrategy and ImprovedNamingStrategy, but not sure how to specify one ...
Hey everyone, I did see the question about setting the proxy for the JVM but what I want to ask is how one can utilize the proxy that is already configured (on Windows). Here is a demonstration of my issue: Go to your Control Panel->Java and set a proxy address. Run the following simple applet code (I'm using the E...
Normally to attach a debuger to a running jvm you would need start the jvm with arguments such as the following: > java -Xdebug -Xrunjdwp:transport=dt_socket,address=1000,server=y,suspend=n Now if I want to debug a process that wasn't started in debug mode, what can I do? This situatoin arrises when a production system (ie started wi...
I'd like to automate data entry into Excel spreadsheets. User data will exist on a web site, and when the user requests it, that data will need to be injected into an Excel spreadsheet. The complication is that the format of the Excel spreadsheet can vary significantly between users - it'll be user defined. I've been thinking of this as...
I have a script that needs to run after tomcat has finished starting up and is ready to start deploying applications. I'm using $TOMCAT_HOME/bin/startup.sh which returns immediately. How can I wait until tomcat has finished starting up? ...
The same as this question but for java Update Based on the comments and responses of a few people, Its clear that Java has very little undefined behaviour. So I'd like to ask as well what behaviour is not obvious. Please when answering make the disticnction between the two :) ...
Hi guys, having a little architectural trouble here. In C++, we have the notion of 'friends,' where such friend classes can access private members. So, I'm deving a Java app and trying to adhere to the MVC architecture. I've got a controller class that manages graph connectivity between 'map_objects.' I'd like to hide the function in t...

I have a flex web app and want to integrate it with Java. The app will have a very small database (2-3 tables), and some routine logic like sending mail. According to this link (http://learn.adobe.com/wiki/display/Flex/2b.+Code+Files), I would need to also have a .jsp file. I thought Flex would only be interested in my classes? Also, ...
Hello again - I am running a query on Sybase ASE that produces a ResultSet that I then traverse and write the contents out to a file. Sometimes, this will throw a NullPointerException, stating that the ResultSet is null. However, it will do this after printing out one or two records. Other times, with the same exact input, I will receiv...
I've been using IntelliJ IDEA at the day job for Java development for a few weeks now. I'm really impressed with it and I'm looking to extend it for other programming languages that I tinker with, starting with Python. I found this plug-in, pythonid. I figured I would look for some input on the Stack before proceeding. First, has anyone...
I inherited an application which uses a java properties file to define configuration parameters such as database name. There is a class called MyAppProps that looks like this: public class MyAppProps { protected static final String PROP_FILENAME = "myapp.properties"; protected static Properties myAppProps = null; public st...
I have 2 different webapps (package into different war files) which needs to share some data via a cache (ehcache). I want to test out this idea with you to see if it works. My idea is to create a service that bootstraps/accesses the ehcache and package that inside a jar. Then package that jar into the two wars: WAR1: ehcache-service....
I remember reading in some Java book about any operator other than 'instanceof' for comparing the type hierarchy between two objects. instanceof is the most used and common. I am not able to recall clearly whether there is indeed another way of doing that or not. ...
What is best language to learn next to Java? Criteria for this secondary language are: High potential of being the "next big thing". e.g. If the market for Java open positions hypothetically dies/dwindles, what is the next programming language that will have a bigger market for open positions? Another way to frame this question is: If...
Why does it (apparently) make a difference whether I pass null as an argument directly, or pass an Object that I assigned the value null? Object testVal = null; test.foo(testVal); // dispatched to foo(Object) // test.foo(null); // compilation problem -> "The method foo(String) is ambiguous" public void foo(String arg) { // More-...
