Re: Glassfish using too much memory
2008-08-19 13:46:01
Hi Felipe,
That is not unusual usage. Your total memory usage is basically going
to equal JVM/Native/thread space + Java Heap + Java Perm Gen.
Calculating the first one is difficult, but it is generally going to be
at least a couple hundred MB. The second is determined by -Xms (start
value) and -Xmx (max value). The final value is determined by
-XX:PermSize (start) and -XX:MaxPermSize (max). You want to take
individual care not to run out of native space, heap space (in any of
the generations), or perm space, all while staying under process limits
(~4GB for 32 bit Solaris processes) and definitely not swapping (KILLS
performance).
Permanent Generation holds all of your classes and methods. In a dev
environment, this could potentially get very large. If you are getting
PermGen errors, try increasing your MaxPermSize (try 128m).

WS-Eventing primer
2008-08-19 13:46:01
I am having to quickly build a java client to connect to a .net Web Service. I was able to use WS-Import to generate code to connect to the service and I am sending requests and getting responses fine, but I can't seem to find any examples or documentation on how to build a WS-Eventing Client... can anybody point me to some documenation or examples on how to do this?
JAXB 1.x stable release download
2008-08-19 13:46:01
Hi,
Where can I find the downloads for JAXB 1.x stable release ? Any URL please ?
I am trying to build a prototype to persist XML using Hibernate (Hyperjaxb2) which uses jaxb 1.0.6 .
I ran into an issue while UnMarshalling. I think I need to play around with JAXB 1.0.6 a little more..
Using HyperJaxb 3 + JAXB 2.x is another option. However, I have a restriction to use Java 1.4
Thanks in advance
Re: unmarshal to java object, but then marshal to an XML based on diff sche
2008-08-19 13:46:01
Sorry to be a kill-joy, but I'm pretty sure that what you're suggesting is impossible.
When you create a JAXBContext, you have to give it class names for the classes which you want to marshall/unmarshall. When you do this. it reads the annotations and solidifies its internal definition of your data. So when you unmarshall xml, you're only going to get objects of the types that you initialized the JAXBContext with.
You could potentially do a piece-wise copy of each piece of data from one class instance with a set of mapping annotations for the first data definition to a class instance with mapping annotations following the second data definition. This seems like overkill on resources, though.
From what you describe, I would suggest XSLT. If you need Java objects in one data format, but still need to validate against the other data format, you can marshall the objects, run the resulting xml stream through a transform, and then validate the result.
Glassfish using too much memory
2008-08-19 13:16:10
I have Glassfish V2 UR1 installed in a Ubuntu 8.04 server. It consumes about
700MB of memory. Is it normal?
In my developing environment memory usage increases so much that I get
PermGen space error.
Thanks for any help,
Felipe

Did that fix it? Inquiring minds want to know.

Re: Glassfish cannot be started(CLI156 Could not start the domain domain1)
2008-08-19 13:16:10
Hi,
it seems CLI156 is just a general error when the domain cannot be started.
The output states that the host "bolpiilinux2" is not known. Can you ping the host? I assume that it is your local machine. Maybe you can try to put the name into /etc/hosts file.
Cheers

See previous post: Re: Error in glassfish server log.
The issue is that Wonderland can't initialize the 3D gaphics:
Caused by: java.lang.NullPointerException: Canvas3D: null GraphicsConfiguration at javax.media.j3d.Canvas3D.checkForValidGraphicsConfig(Canvas3D.java:982) at javax.media.j3d.Canvas3D.<init>(Canvas3D.java:1025) at org.jdesktop.lg3d.wonderland.scenemanager.hud.HUDCanvas3D.<init>(HUDCanvas3D.java:133)
