Error in compilation satge of java files

Hi all
Whenever i m trying to compile java files i m getting this error .I have no idea how to go about fixing this issue. Can any one help me out with this.
Error occurred during initialization of VM
Could not reserve enough space for object heap

Well i could go ahead and solve the issue by bringing down the memory allocation at the minimum and maximum level during the compilation stage.
I got the tip from the forum itself where a similar problem had been reported and there this tip was provided.
Earlier in my case i was allocating 1GB of memory for compilation but due to some issue that much space was not being detected on the server. When i pruned that down to 512mb the compilation went ahead without any trouble.
Thanks kelly for geting in involved in geting to know the issue .

How to compile and run java files on a mac using command line?

can someone tell me or link me to some article on how to compile and run java files from command line on a mac? I have mac OS X leopard

What do you mean by "where to put them" ? What do you want to put anywhere ?
Have you read Peter's comment in brackets ? Perhaps you have a classpath problem ?

How to compile dunamically genrated java files through java program?

Hi, I have a requirement where i generate java files from WSDL dynamically using wsdl2java jaxbri. I need to compile these files dynamically on the fly and jar it. Everything should happen through java program. Bcos everything is dynamic here, no information is known (like dir, file names ...) until the runtime. Everything is user fed.
the directories may contain other directories with java files. its recursive
i tried com.sun.tools.javac.Main.. but either its not scaling to my needs or i donno how to wok with this.
is there any option to compile the java files as they are created thru JAXBRI (wsdl2java)?
any help is appreciated..
-s

my requirement is :
i create java files from wsdl2java (axis).. i need to compile all the java files.. directories with in the directories (recursive)...
as bcos the the java files have inter-dependencies they have to be compiled as a bunch something like (java *.java). I donno how to do this in javac.Main tool
Once all these files are compiled i need to create a jar out of them
Any help is appreciated!

Error: code too large for try statement, when compiling a big java file.

Hi,
I have a big java file ( around 16000 lines). When compiling it, I got following error message:
MyMain.java:15233: code too large for try statement
} catch ( Throwable t ) {
In MyMain.java, I just repeat following statements about 1000 times.
try {

System.out.println( "year: Evaluation version is not valid" );
} else {
System.out.println( "year: Evaluation version is still valid" );
} catch ( Throwable t ) {

I tried 1.3 and 1.4 javac compiler, there was some error.

How to make compiler to compile this code?
You don't. Each method has an absolute limit on the number of byte codes. You have reached that limit. The limit is part of the specification and JVMs will refuse to run classes that exceed the limit. So even if you could compile it, it wouldn't run.
It is quite common for code generators to generate large monolithic blocks of code. Presumably this is how you got to this spot. Modify the code generator to break it into smaller blocks.
If you did it manually then you did it wrong. And you will have to manually break it into smaller blocks. (And re-examine your design since it is probably wrong.)

I have spent hours scratching my head but don?t have a clue. I was wondering if you have any idea as why I might be getting these errors.
Thank you for your time.
Green

Hello, did you read the answers?
You have to put j2ee.jar or servlet-api.jar in your classpath. Those JAR files are included in the Java EE package somewhere. Remove the QTJava.zip junk from the classpath.
If you don't know what the classpath is and how to set it, read this:
Setting the class path
How Classes are Found
And I'll repeat what the others say: if you are very new to Java, then Java EE will probably be way over your head. First learn the language and the standard API. If you understand that well, start with Java EE. Or do you already know what servlets are, and that you need a servlet container to run them, and how to deploy them etc.?

Javac error: Can't read my .java-file

Hi,
sorry for my stupid question, but I have problems compiling my java code.
Before, I used NetBeans to compile the code and I had no problems with it. Now I have to use the javac command (with the same *.java-files) and it does not work.
It's running on Linux. In my current working directory, I have the file
image/transfer/smallserver/RequestProcessor.java
So I type
javac image.transfer.smallserver.RequestProcessor.java but I get this error:
error: can't read: image.transfer.smallserver.RequestProcessor.javaPlease, can anyone tell me, what's wrong with this?
Thank you for your help
Susanne

I set all possible classpathes. It makes no difference.
If I try it a different way, I get other errors concerning the files I want to import. These files are located in image/transfer/client.
I tried to use smallserver as working directory, simply with the command
javac RequestProcessor.javaI get
Class image.transfer.client.ImageObject not found in importI tried it with the same working directory as before with "/" instead of "." in the path name. I get
error: Invalid class file format: ./image/transfer/client/ImageObject.class, wrong version: 46, expected 45and addionally the message from above (ImageObject not found)

Compiling / Running a Java file in JSP

Hi,
ok, I have a jsp page, which we will call page 1. Once I go to that page, I all I want it to do is compile a certain file.java, and then run the file.java. The user doesn't actually know that this is going on in the background. Page 1 automatically redirects the user to page 2 (also a jsp page).
The java program that I created (that was previously compiled and ran) creates a special javascript file. After running the file.java in page #1, the java file creates a javascript file that will be used in page 2 to display a tree node (group of information).
so, right now, I'm trying to figure out how to write the jsp code that will tell how to compile and run a java file. I was thinking about using javabeans before, but I think you HAVE to actually display the contents of the java file into the jsp (I think). Anyhow, thanks for the help!

sorry about being ambiguous before. What I mean by
running a java file was that I already created a java
file. I don't want to hava my java statements inside
the jsp file. I just want the jsp file have a command
in it that would call a java file, tell the java file
to compile and run. All the jsp file would do
(hopefully) is just give commands for a seperate java
file to compile and run. Thanks again for any help!Ok, so this other java file has some entry-point method, like main(), right? So call it...
<%
YourJavaClass.main(appropriateArgumentsGoHere);
%>
or better yet, it's an object you can use:
<%
YourJavaClass x = new YourJavaClass();
x.callSomeMethodHere(withAppropriateArgumentsHere);
x.callAnotherMethodMaybe();
%>
You don't need the jsp file to "compile" this java file, you'd already have compiled it beforehand, and it's class bytecode needs to be in your classpath (on the server side) of course.

Is it possible to compile & run other java files from one file

hi friends,
i need to run 2,3 java sourse files(first.java,second.java etc) from one file.i tried the Runtime.getRunTime().exec( cmd) but here cmd must be a executable file
what is need is to compile and run the files (first.java,second.java) from one other source file
pls. help me in this matter,
with warm regards,
Vishal

Sure:public class Test {
   public static void main(String[] args) {
      try {
         Runtime r = Runtime.getRuntime();
         r.exec("javac Test2.java");
      } catch (Exception e) {
public class Test2 {
   public static void main(String[] args) {
      System.out.println("Hello World!");
}Note that Test and Test2 are in two seperate files.

Ubuntu is not a supported platform. The compiler mostly works, but there are a number of extra issues. Some options like -compat=g are nowhere near usable, even if you use the same version of libstdc++ that is present on the supported platforms.

Compiling a single .java file

Hi,
is it possible to compile a single java class without having to rebuild the complete
application ? If this is not a feature is it going to be available in SP3 ?
Thanks
Mark

Just put your java classes in a Java project under your application and
then compile only that project.

Total time: 3 secondsI'm using JDeveloper 10g. Did someone had problems like this?
I think the problem maybe is caused by jar lib concurrences...
thanks

You get that error when response headers have already been sent to the client (browser). This can happen in two ways that I know of:
- you flushed data to the client, or somewhere the data was automatically flushed
- you already did a redirect/forward and are attempting to do a second one.
So if you want to prevent yourself from getting the error, you'll need to make sure that neither of the situations has occurred. Don't output content unless you are absolutely certain that you won't need to foward/redirect later and don't do a redirect/forward twice in the same resource.

Compiling all possible java files

Hi,
I have a project in which not all files/packages compiles but a set of packages compiles always.
Say set of classes which might not compile as 'A' and set of classes which will always compile as 'B'
On frequent basis i need to get update. And I am only concerned about set 'B' but when i compiles my project using ant
compilation fails as 'A' compilation fails and because of that it doesn't go further to compile 'B'.
So how to get eclipse like functionality to compile all possible files?
what i have is
================================
<javac debug="${debug}" deprecation="${deprication}"
               optimize="${optimize}" destdir="${build.home}/WEB-INF/classes"
               listfiles="${listfiles}" target="${jdk.compliance}"
               verbose="${verbose}" srcdir="${src.home}"
               memoryMaximumSize="512M" fork="true"
               source="${src.compliance}">
               <classpath refid="compile.path"/>
               <include name="**/*.java"/>
               <exclude name="HBM/**"/>
               <compilerarg value="-Xlint:unchecked"/>
===================================
I do not wish to write all the classes specifically that compiles in ant script.
Thanks in Advance

Try with failonerror option in your javac.
        <javac debug="${debug}" deprecation="${deprication}" optimize="${optimize}" destdir="${build.home}/WEB-INF/classes" listfiles="${listfiles}" target="${jdk.compliance}" verbose="${verbose}" srcdir="${src.home}" memoryMaximumSize="512M" fork="true" source="${src.compliance}" {color:#0000ff}*failonerror="false"*{color}>
            <classpath refid="compile.path" />
            <include name="*/.java" />
            <exclude name="HBM/**" />
            <compilerarg value="-Xlint:unchecked" />Regards,

Please tell me how to debug it to make it works, thx

add C:\Tomcat\webapps\examples\WEB-INF\classes to your classpath.
You can do this through the control panel or by:
set CLASSPATH=%CLASSPATH%;C:\Tomcat\webapps\examples\WEB-INF\classes
