[JBoss Tools (users)] - Re: Load Seam example into Eclipse JBoss Tools?
by oneworld95
Thanks, snjeza. After having pulled my hair out for more than a month, I'm giving up on Seam... for now. Haven't been able to make any headway with it. I've found tutorials, try to implement them in Eclipse as a new Seam Project, get to a certain point, and have 10,000 Java exceptions thrown in my face.
This is true of the tutorial here: http://docs.jboss.com/seam/latest/reference/en-US/html/tutorial.html
Got the Registration example working by building it manually in Eclipse using the JBoss Tools. Couldn't find a way to import it successfully and run it.
The app worked for one day. Came back the next day, added another project, now the Registration project was choking too. Hadn't even touched it. It worked one day, not the next. Very brittle technology, and that's why I'm not going to use it right now. Going with JSF and AJAX. That's sufficiently painful.
Someday Seam will be an easy-to-use, pain-free tech, but not right now. It got so bad, I even thought about quitting this job and going back to the dreaded .NET world! I think if I get my Ph.D. in computer science along with some post doctoral research, have a dozen Red Hat consultants sitting next to me, I might actually be able to get Seam to work. In the meantime, I need to get some actual work done before they fire me.

[Performance Tuning] - Re: Maximum XMX value on 32bit Windows Machine
by PeterJ
On a 32-bit system each process is limited to 4GB of address space. 2GB of that is used by the OS (handles and other data used by the OS to service your app), Some of the low memory is occupied by stuff that dates back to MS-DOS. Much of the memory area just below the 2GB mark is occupied by system DLLs (even the JVM DLLs are compiled to load just below that area). The java.exe code loads just above the MS-DOS area. This leaves the memory between the java.exe code and the JVM DLLs available to run the Java app. The JVM reserves some room for the thread stacks.
Given that, the largest heap space I have been able to use is around 1.7GB (the exact number changes with the exact level of the OS and service packs and at time with patches).
You set the permgen to 512MB - this reduced the available space for your heap by that amount, so a 1.3GB max for you sounds about right.
