Exception in thread "main" java.lang.OutOfMemoryError( while importing xml)

I am trying to config application in Sun One Portal server 3.0 SP5 , (Sun Solaris 8)during configuration I was trying to import some xml files however during the process I got the error :
Exception in thread "main" java.lang.OutOfMemoryError.
I tried increasing the size of the heap in jvm12.conf to 512 MB and even tried to run the command -Xms512M, but this didn't help.
Pls respond as asap.

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.
java -Xmx2048m -mx2048m -Xss1024k -Xoss1024m
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

do

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)

//System.out.println("S8: "+s8);
if(s8 != null) stringbuffer.append(s8 + "," + s6);
else
stringbuffer.append(s6);
hashmap.put(s4, stringbuffer.toString());

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"

I have been having issues with FlashBuilder 4.7 and packaging my Flex Mobile application for iOS (simulator, or for install on device).

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.

I have also changed the JAVA_OPTS to -Xms128m -Xmx512m but this didnt solve the issue.

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

Vishal, thanks a lot for your reply. I used the App Server 2004Q4 beta and got the problem. When I switch to version 8.0.0_01 the things work well.
But now I'm trying to understand this example and creating my own simple web app using encryption feature. From the files in the example dicrectory I can figure out the security applied at client by examining client stub files generated by the wscompile in the asant gen-client task. But I wonder when security is added to the server side. Is it when we use wsdeploy with the model part specifiedin jaxrpc-ri.xml? What is the procedure to apply the security to the web service?
The last thing I want to ask is whether the deploytool bundled inside App Server can do the same things as ant task (eg. wsdeploy with some arguments).

Exception in thread "main" java.lang.NoClassDefFoundError

Am using java 1.3.1 on Red Hat Linux 7.1
i get this error
Exception in thread "main" java.lang.NoClassDefFoundError
while running a simple program HelloWorld.java
help

When you use the "java" command, the only required argument is the name of the class that you want to execute. This argument must be a class name, not a file name, and class names are case sensitive. For example, "java HelloWorld.java" won't work because the class name isn't HelloWorld.java, it's HelloWorld. Similarly, "java helloworld" won't work because a class defined as "public class HelloWorld {" is not named helloworld due to case sensitivity. Finally, the .class file must be in a directory that is in the Classpath - that's where java.exe searches to find the file that contains the class.

Hi Java Experts,
I am at a lost to how Java searches for all the classes when running a program. Below are the following steps I have taken to try a simple basic HelloWorld.java program on the command prompt on Windows XP (SP2) platform:
( i ) Installed both jdk1.5.0_09 and Netbeans IDE 5.0 and working properly.
( ii ) The source file is located in F:\Documents and Settings\abc\HeadFirstDesignPattern\src\ch11 and the compiled file is in F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes\ch11 which was compiled in Netbeans.
( iii ) No problem compiling & running this program in Netbeans.
( iv ) The RUN CLASSPATH in Netbeans is F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes.
( v ) No CLASSPATH variable has been set.
( vi ) The HelloWorld program looks like this:
package ch11;
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World!");
( vi ) Got the message
"Exception in thread "main" java.lang.NoClassDefFoundError: HelloWorld"
when running a combination of the following Java commands:
( a ) cd F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes
( b ) java HelloWorld, or
java -cp . HelloWorld or java -cp "." HelloWorld, or
java -cp F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes HelloWorld or "F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes" HelloWorld, or
java -cp F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes;. HelloWorld or "F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes";. HelloWorld, or
java -cp "F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes";. HelloWorld or "F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes";"." HelloWorld, or
java -cp "F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes";. HelloWorld or "F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes";"." ch11\HelloWorld.
It is the package location which is a subdirectory of F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes which caused Java not to find this program. I had no problem running it if the HelloWorld.java was moved one level up. ie from F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes\ch11 to F:\Documents and Settings\abc\HeadFirstDesignPattern\build\classes.
I have written Java in the last year mostly on Netbeans without any problem running them.
The reason for having to learn to run Java on the command line is so that I could add arguments to the program which I couldn't do in Netbeans just yet.
I have gone through a lot of the articles from Java forums, Google searches but yet to have found a solution.
Many thanks,

I am getting the same problem when running the same program on a Fedora 4.0 (Redhat Linux 10) system, together with Netbeans 5.5 and JDK1.5.0_09. Again, I have no such problem when running the same program in Netbeans.
Here are the steps that I have taken as follows:

Stuck for 2 days: Exception in thread "main" java.lang.NoClassDefFoundError

I wrote the code in netbeans 5.5 under windows XP and compiled perfectly. I tried to run the generated Jar file code in the command prompt and it did work perfectly.
C:\Datahub\dist> java -jar Datahub.jar
BUT when I took the jar file and tried to run it under linux here is what I got:
Exception in thread "main" java.lang.NoClassDefFoundError: while resolving class: main.hw

The project i am working on is funded by IBM and they will be really mad if it didn't work :(
Please help.

It is not clear what You want to run under Linux. Jar under JVM or native code? If You are going to use JVM make it clear for Yourself which one You are going to use and then make sure it is installed properly.
