Could not find java.exe

I've installed the jdk 1.4.2 with netbeans, but as i try to execute netbeans i received an error message saying "could not find java.exe"
What do i need to do to fix this error? thanks

Okay, I just moved to a Mac, which automatically has the 1.4.2 jdk installed. So I downloaded 5.0 and NetBeans 4.1. I set the platform for a certain project (I wish I could change the default, but I don't think it will let me) to 1.5.0 but still get an error when I try to use generics and the like. What am I doing wrong?

Could not find jrmc.exe. help required

i have installed jrmc on windows. i want to access it remotely.
http://download.oracle.com/docs/cd/E15289_01/doc.40/e15067/toc.htm
according to instructions, it installed properly.
i could not find jrmc.exe in my windows, to access it.
anyone please help me out.
thanks in advance.

If you installed JRMC using the installer, you should have a new entry in your start menu.
Which version of JRMC did you install?
The installation dir default valyue for the latest JRMC is C:\Program Files\Java\jrockit-jdk1.6.0_29-R28.2.0-4.1.0
If you don't find something there I suggest you try reinstalling.

Eclipse give following error :could not find Java 2 runtime environment

When I try to start eclipse it is giving me following error could not find Java 2 runtime environment.It was working fine untill I installed a new verson of eclipse although I am not whethar that is the source of problem.
When i give java -version command in command prompt it shows
Registry key 'Software\JavaSoft\Java Runtime Environment\CurrentVersion'
has value '1.4', but '1.6' is required.
Error: could not find java.dll
Error: could not find Java 2 Runtime Environment.
My java Home ,classpath , and path are all set as I say it was earliar woking fine.
Please Help.

I know this is a relatively old post, but some people can stumble on this page when doing a search for this problem.
Anyway, I ran into this on my PC after I installed Sybase which had an older jre.
Solution:
1. Run regedit
2. Look for Java Runtime Environment
You may have to do multiple searches. Eventually you'll find one with the version number.
3. Modify the value and change it to the correct version number. (in your case, you would have changed it from 1.4 to 1.6).
This is much quicker than reinstalling Java every time installing something that uses an older version of Java hoses up the registry value.

Consider going to a Windows forum
(or better yet, to Microsoft's web site or to a local book store)
and learning about Vista's "User Account Control".
At least do a Google search on it.

Could not find .java and .class files...

I am working on Windows Vista operating system.
I am able to access the .java which I created and also .class files from the command prompt.
But I am not able to find those files in the bin folder in Windows Explorer.
I want to delete some .java and .class files. When I use the delete command on the command prompt , I am getting ---- could not find the file.
Can anyone help me...

Hey everyone,
I found the answer!
If the command prompt application is run as administrator(since it is windows vista), the created .java files as well as .class files will be stored and can be seen in the bin folder.
However, I could not locate the .java files (and also corresponding .class files) which I created previously.

Could not start java - I dont know what ishappening

I tried reading the early post regarding this problem and also tried some of the solutions provided but still does not start. I am using windows XP.
1. I tried going to the regedit and changed the version to 1.5 still it does not start.
2. Even my path is : C:\jdk1.5.0\bin;[WORKSHOP].
$ javac
Error opening registry key 'Software\JavaSoft\Java Runtime Environment\1.5'
Error: could not find java.dll
Error: could not find Java 2 Runtime Environment.
The only change from the last time that I used java is I restarted the machine that is the only change that I did. So could somebody help me with this please.
I also updated my JRE from java update now still nothing is changing. I would definetly appreicate some hlep in this respect please.

First, a question: You are showing a prompt of a dollar sign, which is not the default Windows prompt. Please explain - are you using a shell program of some sort, or ?
Try this:
Verify that your Test.java source file exists and is correctly named, with the extension of "java". Change the current directory to that directory. Compile using the full path to the javac.exe file - it appears that the command should be:
C:\Program Files\Java\jre1.5.0_01\bin\javac Test.javaIf that compiles, then run the program like this, from the same directory - include the period after classpath and the surrounding spaces:
C:\Program Files\Java\jre1.5.0_01\bin\java -classpath . TestIf these commands work, either the command shell or the Windows path environment variable have a problem.
The path variable in your original post and reply #2 are both wrong. The only Java entry that belongs in the path variable is the path to the javac.exe file, which appears to be the default:
C:\Program Files\Java\jdk1.5.0_01\bin
Also, clean up your classpath, none of the bold entries should be there:
.;C:\Program Files\Java\jdk1.5.0_01\bin;C:\javamyprograms\Privacy-PolicyStudy;C:\javamyprograms;C:\jdk1.5.0\bin;C:\jdk1.5.0\Myprograms;C:\aima;C:\Downloads\junit3.8.1\junit 3.8.1\junit.jar

Could not found java bean

Dear All,
I m try to learn java bean in oracle forms 10g, For the purpose i download an example of color slider from internet and perform all the setps that are define in it . But when i open that example then forms gave me error 'Could not find java bean'. I download example from
http://fdegrelle.over-blog.com/ext/http://sheikyerbouti.developpez.com/index_en/

- did you copy the JAR file in your /forms/java folder ?
- did you add the JAR to your /forms/server/formsweb.cfg file ?
- When you play with Java Bean, ALWAYS display the Java Console at runtime to see if any Java error is raised.

Could not find a valid Java virtual machine to load

On a fresh copy of CFMX8, when I run updater 7, it responds
'Could not find a valid Java virtual machine to load'.
This is being installed on a Win2K3 server and this is on a
'freshly minted' POC box solely for the purpose of
installing/testing CFMX8 to determine how it compares to our
CFMX6.1 environment.
You will notice that it is NOT being installed in the default
directory:

I do find it curious that I can run the Updater 6, and it
seems to behave properly (it finds the VM). I ran it just as a
test, then wiped everything to start over from scratch. For some
reason do I need to direct Updater 7 to the installation that I did
not have to do in Updater 6?
Thank you in advance for your assistance - Jacques

I know this is a relatively old post, but some people can stumble on this page when doing a search for this problem.
Anyway, I ran into this on my PC after I installed Sybase which had an older jre.
Solution:
1. Run regedit
2. Look for Java Runtime Environment
You may have to do multiple searches. Eventually you'll find one with the version number.
3. Modify the value and change it to the correct version number. (in your case, you would have changed it from 1.4 to 1.6).
This is much quicker than reinstalling Java every time installing something that uses an older version of Java hoses up the registry value.
