Java.exe in \jdk1.4.0\bin VS. java.exe in \jre\bin ?

Hi,
What is different java tools in bin directory from
java tools in jre\bin?
Why do we need these duplication?
and what kinds of role jre directory do?
If anyone give any more comments about jdk directory structure
with the reason, it will be big help.
Thank you..

i guess you have installed the java development kit ( JDK ) . I you read the documentation JDK comes with development tools + java runtime environment ( JRE ) . if you have a look at this picture http://java.sun.com/j2se/1.4.1/images/j2se9.2_arch3.1.jpg .It will make it more clear . so what you see in jre folder is for the runtime execution . once you have compiled the java file you you only need the jre content to run it . where as other flders contain development tools , documentation etc .

I have a class "Stimulus.java" in which another jar's class has been used. When I created jar and executed I got below error. I used "-classpath" to set dependancy jar file. Any clues are appreciated.

You can't mix classpath values with the -jar option. Using the -jar option causes Java to use only the Class-Path: information in the jar's manifest file, while ignoring all external classpath information. Review this for details:

WLS : 9.2
Platform : Solaris is 32 bit.
Is the case that with JRockit jdk1.5.0_10 (Release R27.2) JRockit Mission Control is not supported?JRMC works. But there is no JRMC GUI application for Solaries (because the Eclipse RCP libraries are unavailable on that platform). You can enable the JRMC server on the Solaris machine (start JRockit with the appropriate -Xmanagement flag) and connect remotely from a Windows or Linux desktop.
When checked with supported configuration could see JRockit Mission Control 3.1.0 is for Solaris 64 bit.Yes. JRockit JVM including JRMC server. No JRMC GUI.

Getting Web Start to use JDK's javaw.exe, not JRE's

On Windows, I need a Web Started app (actually, my Glossitope desklet) to run with the JDK's javaw.exe, not the JRE's, because I use the Java Compiler API, which is more or less a no-op in the JRE. I've tried using the Java Control Panel to change the Java Application Runtime Settings path to use the JDK path rather than the JRE's, but the change never takes. What, if anything, can I do to get JNLP's to run with the JDK?

Well, using ToolProvider is exactly what I'm trying to do. The program lets you type some Java code, then compiles it and runs it (with help from a custom class-loader). The problem is that when run from Web Start on Windows, ToolProvider.getSystemJavaCompiler() returns null. I can see from the Control Panel that Web Start's path to Java uses the JRE path, not the JDK, and I suspect that's the reason I'm getting null for the compiler.
I suspect bundling the tools jar is exactly what I need to do, and I also suspect the license forbids that.
Works great on the Mac, FWIW.
Thanks for the reply.

Jar files download problems in Java Webstart with JRE 1.6

We have encountered a few problems in Java Webstart with JRE 1.6
In JRE 1.5, the jar files are getting downloaded onto the client
machine with it's original names.
Example :
Server File Name : acm.jar
Client File Name : RMacm.jar
But in JRE 1.6, the jar files are getting downloaded with improper file names.
Example :
Server File Name : acm.jar
Client File Name : 4fb074cc-66fc7407
Moreover the path itself seems to be invalid.
Example Path :
JRE 1.5 path:
C:\Documents and Settings\Administrator\Application
Data\Sun\Java\Deployment\cache\javaws\https\D17.16.23.11\P443\DMtest\DMwebStart
JRE 1.6 path:
C:\Documents and Settings\Administrator\Application
Data\Sun\Java\Deployment\cache\6.0\12
Due to this, we are facing Classpath problems.
What changes do we have to make to the code, for Java
Webstart to work ?
We are using JBoss 4.0.4 and JDK 1.5 in the Server
On the client machine, we have IE 6 and JRE 1.6.01
Help would be appreciated.

Running a java exe without JRE

i have created an exe for a java application by using a C program...The c program invokes the DOS shell and runs the JAVA application...
now how do i make this exe executable on a windows XP machine without JDK being installed...
The second issue is that if i wrap my exe with the required JRE components the size becomes too large...how do i ship my java application as a single EXE runnable on all WINDOWS machines!!!!!!!!!!!

Including the JRE with your app, if you zip it, will add about 14MB to your distribution. It's annoying but in the days of broadband, it's not so much of a problem. You could also check this:

(HP Share to Web)/(java 1.5 JRE) incompatibility problem?

A Java application developed with JDK 1.3, and which used JRE 1.3, ran fine, but upon migrating from Java 1.3 to Java 1.5 (i.e. compiled with JDK 1.5 and using JRE 1.5), the application started having problems running on a given machine, which would give the fatal error, "javaw.exe has generated errors and will be closed by windows." This error would occur after the application would start and when the user would start to interact with application. The problem was traced to the application HP Share-to-Web, which was running on the machine in question. This problem would happen on machines running Win2K and Win98, and the aforementioned application, HP Share-to-Web, but would not happen on XP. When the application, HP Share-to-Web, was uninstalled, the Java 1.5 application would work fine. The following log file concerning this error was written on the Win98 machine. Hey..if anyone has any idea what be a happening, or if someone has experienced this same problem, any response would be appreciated.

AWT strongly suggests gui to me.
That often means video software or hardware problems which can also include fonts.
Does the particular software package grap the screen? And is it certified to work on the OS with the particular video hardware and software (including versions)?

Managing JAVA JDK and JRE with Package Management in Solaris 11.1

I want to manage Java JDK & JRE in an Solaris environment using Package Management I'm currently running Solaris 11.1 in a VMWare host. My current latest Java release is JDK1.7.0_07 and JRE1.7.0_07. I want to upgrade to JDK1.7.0_17 & JRE1.7.0_17 using Package Management. I've tried on several occasions to upgrade to latest release of Java but I have not been successful. Each time I try using the Package Management GUI or use command line they appear to be successful but the new release does not show.
What could I be doing wrong?
Thanks

I also learned that the READMEs for the following patches in My Oracle Support also describe the downgrave process:
Patch 18362676: JAVA 6 DOWNGRADE INCORPORATION FOR ORACLE SOLARIS 11.1.15.4.0 AND 11.1.16.5.0

Java Sound in JRE 1.5.4?

Hello,
I recently installed the Java Run-time envir.. 1.5.4, for windows. Changing from the 1.5.3 version, but in the 1.5.3 version I could play .wav files, but now I cannot.
Would anyone know if the wav player has been taken out, and has to be installed separately?
Thank you

There is no JRE 1.5.4 and there never will be (Sun said there won't be 1.5.x releases with x>0). There is a JRE 1.5.0 Update 4 'though (or 1.5.0_04 in old-speak). I assume you're talking about that.
Is it possible that you installed some additional components inside your JRE-directory that didn't get migrated?

Could not able to RUN Java Programs in JRE 1.5.08

hi
I am using Jdk 1.5.8.
I don�t have any problem in compiling the files.
but i could not able to run the program through windows cmd prompt.
Say name of the java file is newFile (no packages).
When i try to run the program by using java newFile it raises a ClassNotFoundException.
it s the same case when try to set any JDBC drivers ..
is there any problem in my class path settings? Please help me out to fix this problem

if your current directory is not in the classpath,you should include it in the classpath.
To do that you can include .(dot) to your classpath variable.

Java Checker needs JRE to install??

Hi Everyone,
I have just downloaded the Java Checker for Personal Java and am having big trouble installing it. Could someone please advise. This is what it says in the install file:
The JavaCheck installation file is a zip archive that contains a set of
self-extracting class files. The JavaCheck download page describes the
correct method for extracting these files by using the "jre" command.
If you have tried to install JavaCheck by downloading the zip archive and then using an unzip utility to extract its contents, you have made a mistake. You should delete the unzipped files and directories and start over, being sure to use the "jre" command. Read the download web page for detailed instructions.
Could someone please tell me what command I have to use to do this. When I run java against the install class (which I extracted from the zip) I get an exception of not being able to find the file.
Thanks
Dan
