The Rich Engineering Heritage Behind Dependency Injection

Andrew McVeigh takes us on a tour of the rich heritage behind dependency injection, what it represents, and tells us why its here to stay.

Java, the OLPC, and community responsibility

The "One Laptop Per Child" project has a great device ready to ship, but there's no Java on there. Let's think about working together to put Java on OLPC!

Re: Best JVM settings for Eclipse

In my case, the application needs to load average 384M binary data into memory before it can serve as a TCP/IP financial analyzing server. Since 3.2x version, I was suffering OutOfMemory heap memory exception as loading the big bulk data in Memory; finally I probably have solved my problem after I read this discussion.

So far, the configuration of my PC is
** AMD Athlon 64 processor 3000+ with 1GB RAM
** Windows XP sp2
** Eclipse 3.3 Build id: I20070625-1500

I used -vmargs -XX:+UseParallelGC when I start eclipse.exe then I edited VM property in JRE settings in eclipse preference:

Window --> Preferences --> Java --> Installed JRE, choose the one that the project uses (my project uses jdk1.5.0_07)
--> Edit --> at the field [Default VM Arguments] type "-Xms614m -Xmx614m" --> save settings.

Now, I can load the whole 384M binary data into application successfully.

Eclipse JVM settings not written to Registry

Hi,
I have the following jvm arguments which run fine when the application is started in Eclipse but only the first one is written to the Windows registry when the application is installed:

-Dconfigfile=config/coeMatrixProcessor.properties
-Dcom.sun.management.jmxremote
-Xrunhprof:file=dump.hprof,format=b

Is there any reason why this is the case?

Thanks.
