Java Runtime error
Hi,
I Know very little Java. I got a requirement from my client to copy files from one directory to another. I got the following code from Internet. The code got compiled without any error. When I tried to run I am getting the following runtime exception. Please help me to fix this.
C:\Temp>echo %CLASSPATH%
C:\Program Files\VERITAS\Backup Exec\NT\ECM\bumodule.jar;C:\Program Files\VERITAS\Backup Exec\NT\ECM\LOG4J-CORE.JAR;C:\P
LOG4J.JAR;.
C:\Temp>java CopyDirectory('C:\Temp','C:\Y')
Exception in thread "main" java.lang.NoClassDefFoundError: copydirectory('C:\Temp','C:\Y')
Code:
====
import java.io.*;
public class CopyDirectory{
public static void main(String[] args) throws IOException{
CopyDirectory cd = new CopyDirectory();
String arg1 = args[0];
String arg2 = args[1];
File src = new File(arg1);
File dst = new File(arg2);
cd.copyDirectory(src, dst);
public void copyDirectory(File srcPath, File dstPath)
throws IOException{
if (srcPath.isDirectory()){
if (!dstPath.exists()){
dstPath.mkdir();
String files[] = srcPath.list();
for(int i = 0; i < files.length; i++){
copyDirectory(new File(srcPath, files),
new File(dstPath, files[i]));
else{
if(!srcPath.exists()){
System.out.println("File or directory does not exist.");
System.exit(0);
else
InputStream in = new FileInputStream(srcPath);
OutputStream out = new FileOutputStream(dstPath);
// Transfer bytes from in to out
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
in.close();
out.close();
System.out.println("Directory copied.");
Thanks
Leo
The following way of execution fixed the problem.
C:\Temp>java -classpath "%CLASSPATH%" CopyDirectory C:\Temp C:\Y
Just recording for others.

VijayHi Vijay,
Problem is with the standard java users,
Check the status of the ff. and if you choose, try changing the passwords
SAPJSF, SLDAPIUSER, SLDSUSER, J2EE_ADMIN and J2EE_GUEST are the common standard users of the Java Systems.

Java runtime error while executing install.sh - installing Oracle Clinical 4i
Hello DBA's
1. I am trying to install an Oracle App on a SUN SPARC 20 with 256 MB / 9.1
GB. (solaris 8)
2. I installed Oracle 8i EE completely and created the DB using Oracle
Universal Installer. So the Java components and runtime were also installed
I presume. I have it in /usr/java1.2 with links made during install.
3. Did post installation according to the manual.
4. Did pre-installation for install of Oracle Clinical application.
5. Put the OC CD into the drive and typed install.sh as requested.
Error: The Java Runtime environment was not found at
.. /../stage/Components/oracle.swd.jre/1.1.8.10/1/Datafiles/Expanded/solaris/bin/
jre Hence the universal installer cannot be run.
I am struggling for 2 months now and I am hoping that some guru will wipe
out the frustration and anxiety that has made my hair grey. I have also
included the contents of the oraparam.ini for Oracle 8i and Oracle CLinical.
They look almost the same but for some reason, the Oracle Universal
installer does not seem to work for the Oracle Clinical installation.
What could be the reason for this Jav runtime Error. I check the web and
other sites, but no conceivable answer. I have no access to Metalink. What
do I have to do to make the universal installer work.
Your help is really really appreciated.

I put the CD in the CDROM and then cd /cdrom

Would anybody know why I get install.sh NOT found when it is there?. This executabel is on the CD. I am not sure why it gives
a java runtime error message when it is OK. Remember, I have already installed Oracle 8i using the same environment with the existing java runtime .
Thanks for your help.Hi,
I am installing Oracle clinical 4.5.x.
I need to know whether both the Database server and application server for Oracle Clinical can be installed on same server(windows 2000 server).
Both of them are installed on windows platform.
It seems that u have tried the single node installation.
So,please give all the possible details regarding the single node installation for oracle clinical no matter what platform it is.
Please reply me as soon as possible, its urgent.
Thanking u in advance. -
Upgraded to Lion, getting Java runtime error.
I recently upgraded to Lion. Since then I am getting "Java runtime error" and says I need to downoad java, but that I am not connected to the interned. Clearly I am connected to the internet as I am writing this now. Of course Apple wont let me download java myself from the java website.
So heeeeeelp?
thanks!
BradenHi Braden,
you cannot d/l Java from http://support.apple.com/kb/DL1421 ?
Have you tried another browser -- maybe that would work?
Otherwise. the easiest way is of course downloading it on another machine, copying it to a thumb drive and plugging that into your Lion Mac then...
Hope that helps,

I keep getting java runtime error messages
I have updated and installed my java/java runtime. Since then, I keep getting these error messages telling me I need 'to install the java runtime environment". I have already done that. It keeps directing me to the java page to download the update, which I've already done.
Can anyone help me with this? It seems to pop up all the time, both on safari and firefox. I've checked under preferences and allow javascript, etc is checked.This should help.

FLASH CS5: JAVA RUNTIME ERROR
Hi Guys!
I'm facing a serious problem that I can't figure out how to solve it!
I installed the Flash CS5 trial and each time I launch the application, a windows with the message (error initializing java runtime and may need to reinstall Flash )
That's making 6 times that I reinstall Flash CS5, Java 6.21, unisntall, install from CS5 Suite, single Flash CS5 and always the same problem.
I use Windows 7 X86
I tried to find the solution all around the web, the Adobe support and nothing seems to point out the solution!
Is there someone here that can help?
Cheers!Please check the following links for some answers

http://wiki.answers.com/Q/Error_initializing_java_runtime_environment_you_may_need_to_rein stall_flash
I think the idea is that Flash AS3 compiler needs JRE to compile swfs, so please update to the latest JRE version for CS5 to work. You would not need to install, CS5 Flash again and again.

HT5473 Java Runtime error on Mountain Lion
I have been reading the forum on the Java problems with Mountain Lion, but none of the proposed fixes are taking care of my issues. I have the latest version of Java installed from Oracle and have the fix posted on the Apple website installed for the Java SE 6 runtime error I was seeing. I no longer see the runtime error, but programs continue to say that they don't detect Java on my computer. I feel I'm close to resolving this issue, but am obviously still missing a step. Any help?

Alexj55,
I just tried this (I was simply trying to verify whether my removal of Java 7 worked :-):
I opened a Terminal and just typed "java". Mac OSX knew that there was no JRE installed and offered to install one. I agreed. When I did a "java -version" from the terminal after the install was complete, I found that it had installed 1.6u33:
dhcp-110-03:~ twolf$ java -version
java version "1.6.0_33"
Java(TM) SE Runtime Environment (build 1.6.0_33-b03-424-11M3720)
Java HotSpot(TM) 64-Bit Server VM (build 20.8-b03-424, mixed mode)
You might want to give that a try. It was 16:00 US Eastern time when I did this. Good luck.

Tom,
Thanks for the suggestion. Glad to hear some progress is being made by someone! Sadly though, this did not work for me; I got the same error as before. Sticking with it. -
Upgraded to OS X Yosemite, but repeatedly receive Java runtime error
I recently upgraded to OS X Yosemite, despite the fact that I don't like the current version I got one additional problem: I repeatedly receive an alert that I need to install Java Runtime Environment. I did update my Java envrionment for more than 3 times and all the times I verified the environment through an additional step to make sure I have a verified and correct version of JAVA! But this problem still persists ! It makes me go back to previous and old version which I don't want to... Any help???
HI,
I found this thread in regards to your question ( I have the same issue). I've seen we need to install Apple's Java 6, the latest Oracle Java 8 and now this says install Java 7! Can someone PLEASE FIX this issue???? How many Java versions do we need on our computers just because of ONE upgrade? I'm going to try the Java 7 thing and see if it works.

Java Runtime errors in Windows (error=2,3,...)
Hello,
I had a Java progam that makes calls to external programs (of the type of question 2 in the FAQ), but for which I have no access to the code (it is intended for Unix). I have Java installed including the docs (except search API). My question is:
error=2, error=3, error=193 are IOEXceptions which mean something like file not found, not an executable file, the processe returned an exception, etc. Where can I find a translation of those cryptic numbers in plain English, within the docs?. Searching the Internet is not efficient ... TIA
LTJust to add some perspective:
Almost all UNIX platforms provide a file called /usr/include/errno.h (or same name in a subdirectory /usr/include/*/*.h ) as part of the baseline OS. It is only about 100 error codes and is based on the UNIX system calls. This file is provided even for those UNIX platforms (like Solaris) that do not provide any form of C compiler with the OS software (you have to pay extra for the compiler, often a lot extra). Its pedigree goes back to the origins of UNIX.
While Microsoft has a web page with their error code info, they do not provide the file is as part of the baseline OS. I agree that Sun could attempt to provide pointers, maybe as part of a FAQ on their web site. Perhaps Sun does not want to get bogged down with the complexities introduced by a major competitor's legacy issues:
ERRNO.H (for the WIN32 version, about 40 codes, for the C Runtime Library)
ERROR.H (DOS error codes, derived from XENIX, OS/2)
WINERROR.H (12,000 line header file all Win32 codes know at that time, using fields � la DEC's VMS, but includes codes of ERROR.H)
I expect that Sun's implementation of System.exec() calls the Win32 API routine CreateProcess and that probably the only codes you will see returned are defined in ERROR.H -
How to fix java runtime error for 10.7.2
I have a MacBook pro and with Lion OS 10.7.2 and I am getting a message from Java Script "You will need the latest Java(TM) Runtime Environment to print our coupons. Would you like to update now?"
Can anyone tell me how to fix this?That's not a problem with OSX Lion, it is an issue with that particular website (we've seen this before). It's not working with the Mac very well, and there's nothing you can do about it. Sorry.

Cannot remove java runtime error
while instaling i recived error message "internal error 2329.32 ,C:\config.Msi\14c815.rbf"
I now try and remove through add/remove programs and cannot.
Any suggetions?Sounds like there's a problem with the Microsoft Installer that Java uses to install itself. There's a MS tool to repair the MS Installer, these formums hava a mention somewhere, or you can Google the web for information (or search the MS website.)
There might also be a reference to the tool in the help pages at java.com -
