Is there any way to speed up the initialization of javax.xml.bind.JAXBContexts with a large (>1000) number of classes? In our XML heavy application the startup time is some 10 minutes and consists mainly of the initialization time of the JAXBContexts. :-( We are using Sun's JAXB implementation in the JDK 1.5 and the org.jvnet.jaxb2.mave...
This should be really simple. If I have a String like this: ../Test?/sample*.txt then what is a generally-accepted way to get a list of files that match this pattern? (e.g. it should match ../Test1/sample22b.txt and ../Test4/sample-spiffy.txt but not ../Test3/sample2.blah or ../Test44/sample2.txt) I've taken a look at org.apache.comm...
I would like to have multiple Hibernate SessionFactories in a spring application, all of them with identical configurations except for the DataSource. Ideally, I would acquire a particular SessionFactory by name. I need to be able to do this based on runtime state, and it isn't possible to determine which session factories I will need ...

"You want to access the business-tier components from your presentation-tier components and...

This morning, after the number of sessions increased on the machine, Tomcat began throwing 500 errors to users. I checked the logs and found an instance of OutOfMemory, followed by dozens of errors related to Google Guice attem...

Having just wrapped up a GWT-1.5 based project, I'm taking a look at what we'll have to do to migrate to 1.6. I'm very surprised to see that GWT seems to want to write its compiled output to the war directory, where you would normally have items under source control. What's the reason behind this? Did Google really think this was a go...
I have three classes interacting in an interesting way. One is a model class, and it has to be accessed by both of the other classes, so a single instance of it is kept as a member of each. Both of these classes interact with the model in different ways. There are a couple of instances where the model object has to be completely throw...
I have a class which calls out to an existing web service. My class properly handles valid results as well as fault strings generated by the web service.

Hello! I want to make a class usable in SortedSet | SortedMap. class MyClass implements Comparable<MyClass>{ // the only thing relevant to comparisons: private final String name; //... } The class' instances must be sorted by their name property.

Does anyone have a tutorial for building a custom Eclipse IDE with only a select set of plugins? I am assuming I would need: eclipse.exe some plugins from the plugins directory, some folders from the features directory. My goal is to only include the basic text editor and maybe a couple of other utilities. (Yes, I could just use notep...
