Runtime environment required

Hello Friends,
I have installed the developer studio, and when i start it ; give me error msg that a JAVA RUNTIME ENVIRONMNET or JDK must be avaiable to run Eclipse.
I have already downloaded and installed the JDK, and JRE, but did not work, then I set the path as well, did not work, then again I installed under c:\j2sdk1.4.2_15 did not work, then I set the java_home variable to c:\programme\java\jre1.6.0_02, did not worked for me
I set then path to c:\j2sdk1.4.2_15, and also set path to c:\programme\java\jre1.6.0_02\jre\bin, also did not worked for me
Any idea what I have to do inorder to run the studio ?
Regards,

Java SE Runtime Environment 5.0u22 will not install on Windows 98SE

Hi,
I know, its no longer supported.
As I understand, Java SE Runtime Environment 5.0u22 is the last SE Runtime that works with Windows 98SE and, if so, I need to install on a Windows 98SE computer.
This Windows 98SE machine currently has Java 2 Runtime Environment, Standard Edition 5.0 for Windows installed on it.
Downloaded jre-1_5_0_22-windows-i586-p.exe (offline installer version) from Sun, and when I click on this file it invokes my 56K dialer - once online, nothing happens, no HDD activity, no modem lights, nothing - and I do not get any error messages.
If I choose to cancel the dialer, again, nothing happens, no HDD activity, no modem lights, nothing - and I do not get any error messages.
I checked my MSI.DLL file and it is version 2.0.2600.2 - which is consistent with the installation requirements detailed here . . . http://www.oracle.com/technetwork/java/javase/install-windows-139179.html#installer2.0
I ran a few Googles, but did not find any help.
A few words of encouragement and suggestions of how to accomplish this install are sincerely appreciated.
Many thanks,
CurlySue

Well, its been 10 days and no replies.
Bummer.
Guess there are no longer any JSE 5.0 experts online.
Pity.

Removing Java 2 Runtime Environment, SE v1.4.2_04

I'm having problems removing this from my pc. I tried using the Add/Remove Programs and get an error message. Basically it ells me that "The file 'C:\Documents and Settings\Administrator\Local Settings\Application Data\etc.......... is not a valid installation package for the product Java 2 Runtime Environment SE v1.4.2_04 etc.......... etc........
However when I do a browse to that location I do see the .msi package it is looking for. I tried to reinstall the package but cannot because it tells me I already have a version installed. How can I remove this? I'm willing to go as far as doing it manually. Thanks.

The security enhancements are documented at http://java.sun.com/j2se/1.5.0/ReleaseNotes.html#150_06
Changes in 1.5.0_06
Prior to this update [1.5.0_06], an applet or [Java Web Start] application could specify the version of the JRE on which it would run. This has changed. All applets are executed with the latest JRE version. Unsigned Java Web Start applications that specify a version other than the latest trigger a warning, requiring explicit user permission before the application will run. Signed Java Web start applications are not affected.
In other words, only Applets and unsigned Java Web Start applications are affected by the security enhancements. Standalone applications can select any JRE they want, even if it is the outdated 1.4.2_13.

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.

"Error" in ApEx install scripts for runtime environment?

I recently installed a runtime ApEx 3.1 on a 10.2.0.1.0 database. After installing an application which uses the Database Account Credentials method for authentication I was unable to login to the application, getting an ERR-10480 message. After some research on this forum I granted ALTER USER to FLOWS_030100 which resolved the issue. So far so good.
But I was still puzzled as to why the application had worked without problems in a development environment and not in the runtime environment. It took only a few minutes to locate the problem though. In the runtime-install script "apxrtins.sql" there is a call to the "runtime_grant_revoke.sql" script which removes unnecessary DBA system privileges for a runtime environment (which is a good thing IMO). In this script there is also a REVOKE ALTER USER statement, but it seems this one is needed if your application uses the DBACCOUNT authentication method. I didn't find anything on this in the documentation.
Anyone else notice this as well? I would think this is a bug in the install-scripts but perhaps I'm missing something somewhere?

Tim,
Thanks for reporting this. In database server versions earlier than 10.2.0.3, the alter user privilege is required for the "flows" schema to support the feature you mentioned. We'll try to get this fixed in the next patch release.

Keep getting an error message that I need to download Java Runtime Environment

I have a one year old iMac and just downloaded OS 10.10 (Yosemite). Since doing this 2 weeks ago, I keep getting the same error message telling me that I need to download Java Runtime Environment in order for the webpage to run properly. I have downloaded, installed and checked the installation 3x already. The message goes away for a day or two and then returns.
Any idea on what I have not done correctly or need to do further?
Thanks for your he

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Registry key 'Software\JavaSoft\Java Runtime Environment\CurrentVersion'

Server and client are compiled under jsdk 1.3. After a crash on NT workstation installed jsdk 1.4 on it alone. (Did not recompile client to 1.4) All has been well for first few times I ran client on the machine with 1.4 installed. Then client refused to start with following message:
Registry key 'Software\JavaSoft\Java Runtime Environment\CurrentVersion'
has value '1.4', but '1.3' is required.
Error: could not find java.dll
Error: could not find Java 2 Runtime Environment.
Ideas?

I am guessing after installed jsdk1.4, you ran a few tests on the client before restarting the machine, so your java classes are still happy without knowing the registry key has changed. Then after restart, the registry has been picked up and there you go the complaint.
I am also guessing JDK1.3 compiled classes should still works in JDK1.4 environment without recompiled, at least in most of the cases. The registry check is some kind of JVM protection agaisnt version misuse. ??
But all are guessing.

'Software\JavaSoft\Java Runtime Environment\CurrentVersion' Error

Hi Friends,
I've JDK1.5 installed and everything was working fine till I installed JBuilder(i guess which uses JDK1.4).And now when i try to compile my programs from command prompt ,i get the following error.Please help.
D:\>java MailExample
Registry key 'Software\JavaSoft\Java Runtime Environment\CurrentVersion'
has value '1.4', but '1.5' is required.
Error: could not find java.dll
Error: could not find Java 2 Runtime Environment.
[/code

I noticed the JBuilder is using JDK1.4.So JBuilder is written in Java itself.
..while i had
JDK1.5 on my system.So I guess,during installation,it
changed the registry settings to point to
JDK1.4.....can i just set the path..instead of
renaming the folder???I would not expect an IDE to change the system JDK without permission. You can change the path (and any CLASSPATH) settings. However
(1.) Most IDE's would retain their own classpaths so you might need to look for these.
(2.) JBuilder presumeably contains many classes using many API's. Java is not not 100% backwards compatable. It may be worth checking the JBuilder site to see if anyone else has had the same difficulties before you do too much. I am guessing that they have some sort of noticeboard or forums. If not you can always change back later!!!

HKEY_LOCAL_MACHINE\Software\JavaSoft\Java Runtime Environment wrong

Hi,
I am changing my PATH (on NT4) for Java from JDK1.2.2 to JBuilder's JDK1.4, and get such error:
Registry key 'HKEY_LOCAL_MACHINE\Software\JavaSoft\Java Runtime Environment' has value '1.4', but '1.2' is required.
What should I do? Thanks
David

You still have 1.2 jvm (run time). Download and install 1.4 runtime from sun and you should be ok.

How to Force Internet Explorer specific Java Runtime Environment?

Problem: UConn uses a tool called Blackboard. Blackboard requires Version 1.5.0 (build 1.5.0_07-b03)
but I develop so NETBeans IDE needs/wants JDK6 ( likes JDK 6 Update 16 )
Tried managing add-ons in IE, Tried Firefox too.
What I want is to have IE forced to the JDK5 runtime and let my other applications (NetBeans, Oracle, OracleSQLDeveloper, Firefox and MYSQL use the JDK6). I know NEtBeans will allow to specify which JDK but it seems that IE still sees both and screws up.
Things I tried but didnt work: managing add-ons and I saw items like this Force Internet Explorer to use a specific Java Runtime Environment install?
from: http://stackoverflow.com/questions/71254/force-internet-explorer-to-use-a-specific-java-runtime-environment-install
First, disable the currently installed version of Java. To do this, go to Control Panel > Java > Advanced > Default Java for Browsers and uncheck Microsoft Internet Explorer.
Next, enable the version of Java you want to use instead. To do this, go to (for example) C:\Program Files\Java\jre1.5.0_15\bin (where jre1.5.0_15 is the version of Java you want to use), and run javacpl.exe. Go to Advanced > Default Java for Browsers and check Microsoft Internet Explorer.
To get your old version of Java back you need to reverse these steps.
Note that in older versions of Java, Default Java for Browsers is called <APPLET> Tag Support (but the effect is the same).
The good thing about this method is that it doesn't affect other browsers, and doesn't affect the default system JRE.
Any ideas?

Simple then - bad idea.
If your minimal target is 1.5 then you develop in 1.5. If you insist on using 1.6 for functional reasons then you will need to maintain two development environments on your box 1.5 and 1.6. You explicitly build support for 1.6 and detection for that into the code and test it using 1.6. And test using 1.5 as well.
Note you must test both 1.5 and 1.6. Full functional tests.
Obviously limiting yourself to 1.5 would require less effort (cost.)

Proper Runtime Environment for Servlets utilizing SQLJ

I've developed some servlets that utilize SQLJ. They run fine
on the Development system. I want to install the servlets
on another webserver for testing. Is it necessary to install the
entire JDeveloper 2.0 package on the test webserver, just to
provide the proper environment for running the servlets?
I tried to run the servlets on the test webserver by copying
over the java classes found in the JDeveloper 2.0 "jdbc" and
"sqlj" subdirectories to the webserver's "servlet" subdirectory,
and expanding the "zip" files in the "servlet" subdirectory.
I also copied over the contents of JDeveloper's "bin", "java\bin"
and "jdbc\bin" subdirectories, and added the subdirectories
pathnames to the PATH environment variable, but the servlets
still do not run correctly, nor do they raise any java exceptions
before they abnormally terminate. The webserver (Sun's
java webserver) does not, however, "crash" or stop running
when the servlet terminates abnormally.
Again, my question is: does JDeveloper 2.0 have to be installed
in its entirety on a test webserver, just to provide a
proper runtime environment for servlets that utilize SQLJ?
The test webserver is running Windows/NT 4.0 and Sun's
Java Web Server 1.1.3.

Raghu:
Thanks for the info (below). Using the current production copy
of JDeveloper, I've successfully run servlets containing SQLJ.
I am attempting to put together a deployment package for a
database servlet that utilizes SQLJ. When the java webserver
attempts to initialise the servlet and connect to the database,
an exception is thrown.
The SQLJ Statement causing the exception is:
conn = DriverManager.getConnection(connect_string,"its1","its1");
The exception is:
java.lang.UnsatisfiedLinkError: make_c_state
at oracle.jdbc.oci7.OCIDBAccess.logon(OCIDBAccess. java:142)
at
oracle.jdbc.driver.OracleConnection.(init)(OracleConnection.java:
93)
at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:146)
at java.sql.DriverManager.getConnection(Compiled Code)
at java.sql.DriverManager.getConnection(DriverManager.java:134)
I assume that "make_c_state" is a link to a "dll" package. Could
you (or someone else) tell me what package I need to include in
the distribution in order to satisfy this linkage requirement?
I am attempting to put together a distribution package that
does not require installing the entire JDeveloper 2.0 suite on
the target marchine running the webserver ,which I believe it is
necessary to do when following the instructions for deploying
database servlets via the instructions contained in the
JDeveloper on-line help information.
I have a second, related question. Our facility will be
installing a new "production" webserver that will be running
UNIX, not Windows/NT. Will it be possible to deploy the java
servlets (which utilize SQLJ) on this platform? To my knowledge,
JDeveloper 2.0 is currently available only for the Windows/NT
platform.
Thanks,

Why do I get a warning about downloading J2SE Runtime Environment?

I want to take some courses through SkillSoft, it requires downloading a Java Runtime environment. Before I even started to download I got a Firefox message about something being blocked and that the JRE could cause stability or security problems? I closed the window so I don't have the exact message. Should I download the JRE or not?

Welcome to the Support Communities. So that we can see exactly what you're referring to, please take a screen shot of the warning and post it using ASC's camera icon:
