hallo
i need your help
first my java j2ee and jdk
j2ee j2sdkee1.3.1
jdk j2sdk 1.4
i nedd the server for jms.
when i started the server with j2ee -verbose
i get the error message:
Starting web service at port: 8000
Exception in thread "Main" java.lang.OutOfMemoryError
what can i do to get out off this error message and starting the server normal. please help me to solve the problem!!!
i read in this forum about -Xms und Xmx but this Commands don't go on my system.
thx for help!!!

Hi Warren,
Still I am not clear with your question. But generally this out of memoryspace error can be rectified by changing the properties which comes in the menubar of your command prompt. Then increasing the virtual memory over there. I hope this will help you.
Thanks

Hi gimbal2,
yeah, its streaming the particular data (ie CUSTOMER) from input xml file and generate the txt file.
I tried like below . But this is also not working. Getting the same error.

Any other possible solution on this?

FB 4.7 AIR 3.6 Flex 4.9 iOS packing - Exception in thread "main" java.lang.OutOfMemoryError'

I've got an error similar to Isaac_Sunkes' 'FB 4.7 iOS packaging - Exception in thread "main" java.lang.OutOfMemoryError',
but the causes are not related to what he discovered, corrupt image or other files, I'd exclude bad archive contents in my project.
I'm using Flash Builder 4.7 with Adobe AIR 3.6 set into an Apache Flex 4.9.1 SDK;
HW system is:
iMac,    2,7 GHz Intel Core i5,    8 GB 1600 MHz DDR3,    NVIDIA GeForce GT 640M 512 MB,    OS X 10.8.2 (12C3103)
The Flash project consists in an application with a main SWF file which loads, via ActionScript methods, other SWF in cascade.
I've formerly compiled and run the application on an iPad 1, IOS 5.0.1 (9A405), but got on the device the error alert:
"Uncompiled ActionScript
Your application is attempitng to run
uncompiled ActionScript, probably
due to the use of an embedded
SWF. This is unsupported on iOS.
See the Adobe Developer
Connection website for more info."
Then I changed the FB compiler switches, now are set to:
-locale en_US
-swf-version=19
Please note that without the switch    -swf-version=19     the application is compiled correctly and the IPA is sent to the device
and I can debug it, but iOS traps secondary SWF files and blocke the app usage, as previously told.
they work on deploy of small applications,
but, when I try to build a big IPA file either for an ad-hoc distribution, either for an debug on device, after some minutes long waiting, I get a Java stuck, with this trace:
Error occurred while packaging the application:

I've tried to change the Java settings on FB's eclipse.ini in MacOS folder,
-vmargs
-Xms(various settings up to)1024m
-Xmx(various settings up to)1024m
-XX:MaxPermSize=(various settings up to)512m
-XX:PermSize=(various settings up to)256m
but results are the same.
Now settings are back as recommended:
-vmargs
-Xms256m
-Xmx512m
-XX:MaxPermSize=256m
-XX:PermSize=64m
I've changed the Flex build.properties
jvm.args = ${local.d32} -Xms64m -Xmx1024m -ea -Dapple.awt.UIElement=true
with no results; now I'n get back to the standard:
jvm.args = ${local.d32} -Xms64m -Xmx384m -ea -Dapple.awt.UIElement=true
and now I truely have no more ideas;
could anyone give an help?
many thanks in advance.

I solved this. It turns out the app icons were corrupt. After removing them and replacing them with new files this error went away.

Exception in thread "main" java.lang.OutOfMemoryError(please help me )

Hi All
here my java class trying to read a txt file(which is having size of 60MB).and putting each line into a Vector class. problem is ,upto certain number of line it is reading properly and putting into vector..after that it is giving error like Exception in thread "main" java.lang.OutOfMemoryError..what is the problem and how to rectify this one..anybody help me on this.
actual situation is one txt is there in that 80 lakhs of lines of content is there..java file trying to read each line and put it into vector or stringbuffer and split it into two lines like key=value and put it into hashmap object.then finally iam creating new file(.properties) and writing these hashmap data on it. if you want clearly..please look into below code..
package test.utf8; import java.io.*; import java.util.*; public class AssetUtils
//static StringBuffer stringbuffer = new StringBuffer();
public AssetUtils()
public static void main(String args[]) throws IOException
BufferedReader bufferedreader = new BufferedReader(new InputStreamReader(new FileInputStream("D:\\list.txt")));

System.out.println(vector.capacity());
Object obj = null;
int n=0;
System.out.println("Reading list:" + new Date(System.currentTimeMillis()));
do
String s = bufferedreader.readLine();
//System.out.println("line no: "+ ++n);
if(s == null)
break;
vector.add(s);
} while(true);
System.out.println("List Read complete:" + new Date(System.currentTimeMillis()));
String s1 = args[0];
System.out.println("S1: "+s1);
System.out.println(vector.capacity());
HashMap hashmap = new HashMap();
System.out.println( "Vector.Size..>>>>>>>>>>>>>>>>.."+vector.size());
for(int i = 0; i < vector.size(); i++)
System.out.println("i value:"+i);
String s2 = (String)vector.get(i);
//System.out.println("S2: "+s2);
if(s2.indexOf("/") != -1)
String s3 = s2.substring(s1.length(), s2.length());
//System.out.println("S3: "+s3);
if(s3.indexOf("/") != -1) {
String s4 = s3.substring(0, s3.lastIndexOf("/"));
//System.out.println("S4: "+s4);
String s6 = s3.substring(s3.lastIndexOf("/") + 1, s3.length());
//System.out.println("S6: "+s6);
StringBuffer stringbuffer=null;
stringbuffer = new StringBuffer();
String s8 = (String)hashmap.get(s4);
//System.out.println("S8: "+s8);
if(s8 != null) stringbuffer.append(s8 + "," + s6);
else
stringbuffer.append(s6);
hashmap.put(s4, stringbuffer.toString());
//stringbuffer.delete(0,stringbuffer.length());
stringbuffer=null;
System.out.println("Opening asset.properties:" + new Date(System.currentTimeMillis()));
File file = new File("D:\\asset.properties");
PrintWriter printwriter = new PrintWriter(new FileOutputStream(file));
String s5;
String s7;
for(Iterator iterator = hashmap.keySet().iterator(); iterator.hasNext(); printwriter.println(s5 + "=" + s7))
{ s5 = (String)iterator.next(); s7 = (String)hashmap.get(s5); } printwriter.close();
System.out.println("Closing asset.properties:" + new Date(System.currentTimeMillis()));

Theres a number of ways you can improve your memory usage:
1) Build you map as you read in your file.
2) Use StringBuffers in your map - do not use "asshaj" + "ashaskj" This is very memory intensive
If you still run out of memory try running the JVM using -Xms128m -Xmx512m or higher

FB 4.7 iOS packaging - Exception in thread "main" java.lang.OutOfMemoryError"

Check your code where u set the connection query; there's a procedure in my DBConnection class, looks like this:
public void setQuery(String query) throws SQLException {
this.query = conn.prepareStatement(query);
Should look the same for u, at least similar.
I set the query this way: dbConn.setQuery("insert into groups (id, code, sectionID, languageID, year, no_students) values (?,?,?,?,?,?)");
I had to insert 24,827 records into a table, and it throws the heap space exception u mentioned when it reaches 12,667. So what i did was to put dbConn.setQuery(...) outside the loop, and inside the loop it remains to set the parameters and execute the query from connection. It works for me. Hope will help u save some memory space.

How do I stop "Exception in thread "main" java.lang.OutOfMemoryError.java heap space

I'm trying to rebuild my iPhone app, with hires graphics etc, using CS6 Flash Pro. However, I get this now,
Exception in thread "main" java.lang.OutOfMemoryError.java heap space ..... followed by a lot of location information related to the error.
Now, how do I increase the java memory allowances if that's the problem. I've already upp the jvm.ini file from 128 to 512. No difference.
I'm based on
Win8, 8GB RAM, x64
I'm obviously asking it to load a lot of resources - but hey, Flahs should be able to handle it right?
thanks if anyone can help

Hmmm. Maybe I was doing something wrong with images, and icons. I'm not sure, as it's not at all clear really.
This is the Icons screen from CS6, can't see the files above 512x512unless scrolling up - 29x29,57x57,114x114. no matter.
So - after reading and rereading the Apple specs and directions, I removed the 512x512 and the 1024x1024 images from the Icons list that get pulled in during build.
Next, I again re-read the Apple directives, and put the required files for the build into the base directory of the build, as per this image.
In actual fact - I can probably leave out the last two. iTunesArtwork.xxx But I don't know, because it is entirely unclear on that point. I can find no directive regarding this at all.
Do I upload them myself? Probably? I don't know.
HOWEVER.
The build now completes. Java, or something, was very confused about finding that file called 1024x1024.png in the build list, and would not do it.
Take it out of icons, built fine. Put it in the icons directory, and crash...
Now - with the setup I am using, it all builds fine for ipad and iphone, in all resolutions.
I don't know what the problem is with what Java is seeing, but this fixes it it seems.
Hope that helps anyone else.
cheers

Put the hsqldb JAR file into your classpath. I suspect Mr Singh was using ".." when he should have been using "." in the classpath string, but even if he wasn't his classpath issue's not that likely to be identical to yours.

The server is starting fine with domain variables without changing the memory arguments in the managed server startup scripts.
But when i changed the mem args in the server startup script , this is the error and server is not starting.
the domain env is set and weblogic server version 9.2
Here is the arguments i changed in the startup script, the server is starting with out these arguments with domain set memory arguments. Any body please help
USER_MEM_ARGS="Xms512m -Xmx512m -XX:MaxPermSize=128m"
export USER_MEM_ARGS

I think you are missing a character '-'
USER_MEM_ARGS="Xms512m -Xmx512m -XX:MaxPermSize=128m"Add this character like follows
"-Xms512m -Xmx512m -XX:MaxPermSize=128m"

Error: Exception in thread "main" java.lang.NoClassDefFoundError:

Hi
I have seen this problem on a few forums but have not found an answer that works for me, sorry if missed it!!
The command I am giving is:
C:\Program Files\Rococo\ImprontoSimulator\examples\echo\bin>echo-server
Exception in thread "main" java.lang.NoClassDefFoundError: com/rococosoft/impronto/examples/echo/EchoServer
this runs the following batch file:
@echo off
set CLASSPATH=
set CLASSPATH=%SIMULATOR_HOME%\lib\isim_j2se.jar;%CLASSPATH%
set CLASSPATH=%SIMULATOR_HOME%\lib\log4j.jar;%CLASSPATH%
set CLASSPATH=%SIMULATOR_HOME%\examples\echo\lib\echo.jar;%CLASSPATH%
java -classpath "%CLASSPATH%" com.rococosoft.impronto.examples.echo.EchoServer
this is where I assume all the CLASSPATH's are set.
Any help would be very much appreciated.
Thanks
Nitin

Once you have defined your classpath as an environment variable, it shouldn't be necessary to include it (or quote it) within the command line. In other words,
c:\> java EchoServer
should have worked. However, I suspect the reason the batch script doesn't work might be because %SIMULATOR_HOME% isn't defined? If Java can't find any of the libraries, then it can't find a class EchoServer that contains a main() function to call, resulting in the error message you've received.

Exception in thread "DoSManager" java.lang.OutOfMemoryError: nativeGetNewTLA

Hi,
We are facing this 'Exception in thread "DoSManager" java.lang.OutOfMemoryError: nativeGetNewTLA' exception in our production logs. Our JVM as part of WebLogic Server is BEA JRockit(R) Version R27.6.5-32_o-121899-1.6.0_14 and linux-x86_64.
This is how our JVM is configured:
a. Stack size(-Xss)
--This is not configured
b. Heap size
---Xms2048m -Xmx2048m
c. XXtlasize
---This is not configured
d. XXlargeobjectlimit
---This is not configured too
As I understand if we don't configure above parameters then default values will be considered. Our concern is whenever this exception occurs our application crashes obviously because JVM is not able to execute the code because of insufficient memory. Do we need to tune our JVM or do we need to fix issues in our code? My next task is actually to do the Heap Dump analysis on the Production heap dump which would have been taken when there is an 'OutOfMemoryError' outage for better analysis. For heap dump analysis we will be using MAT.
Any suggestions regarding this would be welcomed.

You are leaking memory or attempting to use to much. There is a bug in your code.
