How To Increase heap size in Java Studio Creator 2

Hi,
I'd like to know how I can increase the heap size in Java Studio Creator 2.
I already tried editing creator.conf, but it doesn't seem to work...
Can anybody help me?
thanks.

In the servers window of creator, right-click 'Deployment Server' and choose 'View Admin Console'. A new web page comes up with the web interface to the Sun Application Server 8. Type your username and password that you configured during installation. I think default username is admin and default password either admin or adminadmin. After you're in, click 'Application Server' link in the left window, then click 'JVM Settings' tab, then click 'JVM Options' tab. Add new JVM option -Xms512m to start the server with 512MB. Find the -Xmx option and edit it to something larger, provided you have enough memory on your system.

How to increase heap size in Java in detail?

I am writing an java app in eclipse that do need a lot of memory.
The default
java -Xms32m -Xmx128mis not enough.
I want to change it to
java -Xms128m -Xmx512mI opened the command line in windows xp and changed the current directory to the installing place of jre and jdk.
But under either directory after I ran the above command, it returns help information like
C:\Program Files\Java\jdk1.6.0_05\bin>java -Xms128m -Xmx512m
Usage: java [-options] class [args...]
           (to execute a class)
   or java [-options] -jar jarfile [args...]
           (to execute a jar file)
where options include:
    -client       to select the "client" VM
    -server       to select the "server" VM
    .......Have I changed the heap size successfully?
How can I verify it? I am using eclipse 3.2 running the application.
Please offer me some help. Many thanks!

It is showing you the help message, because you forgot to specify a class. When you call the "java" command, you have to say a class name after the -Xms and -Xmx commands.
So, do this:
java -Xms128m -Xmx512m classNameWhere className is the main class of your app.
Best of luck.

How to do internationalization with Sun Java Studio Creator?

Hi everybody,
the Sun Java Studio Creator seems to be a great peace of software ;-) Currently I'm trying to design some forms for a hello-world-test-project. My question now is: how can I realize internationalization with property-bundles? I already managed it to create my own bundles, I set up a few locales (de, en, fr) and put in some "SayHello" Variables. But how can I associate my locale-variables in the .propertie-files with the value- or text-attributes of the UI-Components using the form designer?

well... it's not working!
I created some locale-properties. Put a
<f:loadBundle basename="mypackage.mainlocales" var="messages"/>directly under the "<f:view>"-Tag as it is descriped in the manual.
But when I write something like
<ui:label binding="#{sites$main$mainmenu.label1}" id="label1" style="position: absolute; left: 312px; top: 168px" text="#{messages.test}"/>The designer crashes with an error-message:
javax.faces.el.PropertyNotFoundException: Error testing property 'test' in bean of type null

i think the best thing for you to do is to use javascript. go to jsp page of the form and find the button, as part of its attribute type onClick="window.print()"

How to increase heap size in OC4J .

Hi Friends ,
I am getting out of memory exception,so i need to increase the heap size , so kindly provide me the information where and how could I increase the heap size in OC4J ?.
Yrs
Jeyaprakash

you should be able to pass the java heap options when starting the container:
-Xmx1024M
So if you are starting the 10.1.3 container from a Windoz command file you could use:
setlocal
@echo off
set ORACLE_HOME=C:/Programs/oc4j-10.1.3
set JAVA_HOME=C:/Progra~1/Java/jdk1.5.0_07
set J2EE_HOME=%ORACLE_HOME%/j2ee/home
%JAVA_HOME%/bin/java.exe -Xmx1024M -jar %J2EE_HOME%oc4j.jar

JGrasp -- how to increase heap size?

Hello, can anybody tell me how to increase the max heap size in jGrasp?
Thank you.

Thanks.. I tried that, but I'm not sure that it
increased the heap size. I tried using that method
to set it to 512MB (-J-Xmx512m), and when I open up
System Properties within jGrasp, it says:
Free Heap: 7,805,040
Total Heap: 19,812,352
Max Memory: 532,742,144That is what you would expect with a 512MB max heap.
And then I put the following lines of code in my
program:
long max = Runtime.getRuntime().maxMemory();
System.out.println("Runtime.maxMemory():
): "+max/1024/1024+" MB");
And the output that I got was: "Runtime.maxMemory():
63 MB"You have set the max heap for jGRASP itself, which you
might need if you are editing some huge files or
something and jGRASP is running out of heap. Max
heap for user programs is a different issue. To change
that, on the compiler settings for the current workspace
or project, in the "Flags/Args/Main" tab, add Java flags
like "-Xmx512m" to "Flags2 or Args2" for the "Run" and
"Debug" rows.

Problem increasing heap size using Java Control Panel

I am running a web-based bioinformatics package which uses a Java applet as the client application. It mostly works fine, but some large clustering processes don't complete, they just cycle endlessly. The user manual advises increasing heap space "by entering the following command in the Java Control Panel or Java Plug-in dialog: -Xms128M -Xmx256M." I can open the Java Control Panel OK and enter the necessary command in the Java Runtime Parameters box, but after clicking OK then Apply, the Runtime Parameters box is empty again and there is no increase in the heap size allocation. In other words, the change doesn't take effect.
I have already tried: adjusting one parameter at a time (max heap size first, then min); changing uppercase to lowercase M (-Xmx256m); restarting the browser after the change; rebooting my PC - none of these has helped.
Technical details: it's Java 6 standard edition, build 1.6.0_10-rc-b28; browser is Internet Explorer 7; operating system is Vista (Service Pack 1); PC is a 2.4 GHz processor with 2 GB RAM (so I have plenty available to allocate to Java). I have local admin privilege on my PC.
Help would be much appreciated, as I really need to complete these cluster analyses. I'm a biologist not a developer, so ideally I need a solution that doesn't involve major programming, though I'm OK with registry edits and use of the command line. Thanks in advance.

The failure to retain the parameters is a bug, per hdong in this [Java,net thread|http://forums.java.net/jive/thread.jspa?threadID=44540&tstart=0] dated August 14
"I did a little more research and found out that the problem is only with "-rc" or "-beta" versions of plugin. When 1.6.0_10 is finally released, the version string will be "1.6.0_10". Plugin works fine to set/get jvm parameters when version string is "1.6.0_10".
I am surprised that this issue was not discovered earlier. It was probably because the internal test binary use "1.6.0_10" as version string.
Yeah, it is a bug that will affect many manny developers. It will be fixed as soon as possible."

How to increase Heap size at runtime

And unless there is no reason to be swapped out
(plenty of physical memory) then it will be swapped
out.I don't understand this. If there is no reason to
swap a page back to the disk - e.g., there is plenty
of available phyiscal memory for some other process -
then why would the OS bother to swap that page back
out to the disk?Ok I don't understand the statement either :)
So obviously I need to rephrase it.
Page swapping only occurs when needed. If there is plenty of physical memory to hold everything, then swapping does not occur.
On the other hand if there is not enough physical memory then pages will be swapped out.
>
And application can also tell the OS that it nolonger
wants to use some memory (pages.) But what doesthis
gain the application? After all if it kept thememory
and simply did not use it, it would not affectother
applications. That is because the memory isswapped
out to the harddrive until needed. So there is no
need for an application to return memory to the OS.But since virtual memory is finite and there is a
performance overhead if there is frequent swapping of
pages into physical memory and out from the disk
(thrashing), overall performance/throughput degrades.Some what correct. First virtual memory has a finite limit. But that limit itself does not affect other applications.
Virtual memory in of it self does not cause swapping. If I allocate 1 gig for my application, when my application runs it will not have 1 gig of physical space. Only the memory that is 'touched' is relevant to the OS. So during a time slice it might be the case that only 16k of actual physical memory is used - say 8k for the small piece of code running and 8k for data (an over simplification but appropriate for this discussion.)
It is rather unlikely, perhaps even impossible, that the entire 1 gig of memory would be swapped into memory during a single time slice.
If the process' consumption of memory can not be
streamlined, then that's typically when people go and
buy more physical memory, no? Or in some cases,
increasing the amount of virtual memory available to
the OS can alleviate the problem.There is a difference between requesting memory and using memory. Memory that is used ('touched') is the only thing that has to be in physical memory. If you do indeed use a lot of memory in your application then more physical memory will help. But simply requesting more memory doesn't impact physical memory.

How to Increase Java Heap Size through Java Code. Increase inside Code?

Hi All,
I am using a third party tool. When i run a particular program it says OutOfMemory error. I like to increase heap size through Java Code before calling the particular Java application or Code..
Is there is any way to set the Heap Size through Java Code in run time ???
Pls Kindly help.
Thanks.

if you start the program with a -Xmx512m flag, the virtual machine gets half a gigabyte of memory to use (or that's the max it's allowed to use). All things run in the same virtual machine will have the same limit, third party tools run in the same virtual machine can't "not care about this" unless they're throwing OOMs themselves for some stupid reason.

As of 1.0 Creator doesn't support creating HTML frames via the designer. However, it may be possible to edit the JSP source to include one by hand.

Need to improve Java Studio Creator performance

Can anyone has a suggestion on how to improve the performance of Java Studio Creator? JSC works fine when you have a less than 50 java files but when your building a large project JSC IDE works slow in terms of loading the whole project, modify the page in design layout, drag and drop a component or even modifying some java codes.The PC had a 2 GB memory. I'm grateful for any suggestion you can give. :D

Hello, i supossed u r using Windows right?, and running in a x86 machine?. Ok well, even Windows XP is not so "Strong" enough to run Creator with a decent performance, i can say this because i have at home a PC Windows XP Pro, Intel Core 2 Duo Processor, 2 GB RAM, and HD Seagate Barracuda 120 GB ATA and Creator Still hangs some time, my suggestion is:
Install Solaris in your pc, I've installed Solaris 10 11/6 in the pc ans runs great (the x86 vesion). I have a Sun Ultra 20 with 1GB RAM and 3 projects at work with more than 150 pages and works fine.
