Could not find the OffLine WLST class

I am trying to install Oracle ATS 12.5.0.3. on Windows 2008 R2 server.
At the end of the installation I get a warrning, that some actions failed. After looking into a log, I found:

... 7 more ERROR: Unknown error (code: 1)
After some research, I tried to set CLASSPATH system variable to "." (it was not set at all previously). But it made no difference...
I am out of ideas how to fix this. Can somebody please help me?
Thanks in advance.

I faced the same issue today, installing OATS 13.1.0.1. Basically, it fails at the step of installing FMW (fusion middleware). It seems to fail because its installation step checks a lock file which was already created by the setup.bat.
Steps to correct this issue:
Uninstall clean. If uninstall/bin/uninstall.bat did not work, stop Oracle ATS services and delete them using regedit
Install FMW first. You can find fmw jar file from fmw folder in your unpacked OATS installation package directory (your fmw jar file name may vary). This step requires cmd run as administrator and the java should be from your jdk location
java -jar fmw_12.1.3.0.0_infrastructure.jar
To make this jive with the next step, you can choose C:\OracleATS\wls (or [the directory of your choice for OATS installation]\wls) for Oracle Home.
If you have failed the installation step before, it might have created the OLT schema in your local database. To avoid this issue, use your favorite SQL client to run these commands
drop user oats cascade; drop user olt cascade; drop user otm cascade;
Now run setup.bat to install OATS, use custom, unselect fusion middleware before continuing on installation
Once installation is finished, you can check it by visiting http://localhost:8088/admin/LoginSubmit.do and login using administrator:[password you set during installation]

i am not able to find the class,
com.oracle.cie.domain.script....
so i have done the following,
I have used all jars in wlserver\server\lib in classpath now the issue is resolved.
and added -Dweblogic.home= -Dbea.home=
now i have resolved the issue.

Running this on a Windows 10 box. I even tried using the msys git bash shell thinking maybe that would help the JVM simulate a chmod operation. Didn't change anything. Any suggestions on how to do this on Windows?

I too faced this error and it was resolved after following the steps. (Note : I am using Spark 2.0.2 and Hadoop 2.7)
Verify whether you are getting "java.io.IOException: Could not locate executable null\bin\winutils.exe in the Hadoop binaries.". You check it by running "spark-shell" command.
I got the above mentioned error. It occurred because I didn't add "HADOOP_HOME" in environment var. After adding the "HADOOP_HOME", in my case same as "SPARK_HOME", the issue was resolved.

Running a Hadoop program using only jars on Windows requires a few steps beyond just referencing the jars.
Credit to Professor Lu at University of Helsinki for posting a Hadoop on Windows guide for his students.
Here is a rundown of steps I had to take using Windows 10 and Hadoop 2.7.3:
Download and extract Hadoop binaries to somewhere like C:\hadoop-2.7.3.
Download patch files from https://github.com/srccodes/hadoop-common-2.2.0-bin/archive/master.zip and extract them to your %HADOOP_HOME%\bin directory.
Set a HADOOP_HOME environment variable. For example, C:\hadoop-2.7.3.
Download the Hadoop source code, copy hadoop-common-project\hadoop-common\src\main\java\org\apache\hadoop\io\nativeio\NativeIO.java to your project, and modify line 609 from
return access0(path, desiredAccess.accessRight());
to
return true;

One of the solutions is as follows.
In the Project Structure (Intelij), under SDK's ensure there is no other version of Hadoop referenced. In my case - I was running Spark earlier and it was referring Hadoop JAR's and this was causing access issues. Once I removed them and ran the MR job it ran fine.

PWC1231 and PWC6344

I have two servers running on Glassfish 2.1 both have the same web app.
Two times this error occurred: Some jsp pages stop displaying only showing a blank page, and the following errors are printed in the logs...

Followed by this:
PWC6344: Unable to create output writer for file /path/to/jsp/file/jsp_file.jsp.java|#]
Sometimes only the PWC6344 error is printed and sometimes both, the PWC1231 error is always followed by PWC6344 (which somewhat makes sense, because that exception is thrown when an IOException occurs).
Well, both times this errors happened, the only thing I did was stop and start the instance, and everything was alright again, also this error has only occurred in one of the servers.
Whats is happening ?... Or how can I diagnose what is causing this so I can fix the problem instead of stopping and re starting for eternity...
UPDATES:
I was looking into the possibility of this been a file descriptor problem, as suggested by sbridges but!, the maximum number of file handlers is 811975 with 4520 opened files in one server and 359532 with only 6894 in the other.
So, I guess its safe to say this is not the problem!
Does someone have another theory?

It looks like the permissions are set incorrectly and you can't write the compiled jsp page to disk,
/path/to/jsp/file/jsp_file.jsp.java (Permission denied)
Are the permissions correct on that directory/file?

Rename jsp_file.jsp.java to jsp_file.jsp.

PWC6344: Unable to create output writer for file /path/to/jsp/file/jsp_file.jsp.java|#]
This can also happen if the underlying operating system has run out of file handlers/descriptors which are required in order to open a file for reading or writing. I'm not closely familiar with CentOS, but Google hints that it has a "relatively low" limit of 1024 given the lot of problems related to it in the search results. Among the results you'll see a lot of questions/answers as to how to increase it, such as the following blog:
Increase the number of file descriptors on Centos and Fedora Linux
Raising the number of file descriptors for a regular user on CentOS/Fedora/Redhat is surprisingly difficult to learn how to do. There are lots of incomplete walk throughs on the web, some with typos and other problems.
Here are the steps that worked for me to raise the open file descriptor limit from 1024 (the default) to 65535:
As root, edit /etc/sysctl.conf and add the line:
fs.file-max = 512000
At the bash prompt, run:
$ sysctl -p
That will cause the settings to take effect. You can also cat 512000 > /proc/sys/fs/file-max but that may reset on reboot.
Edit /etc/security/limits.conf and add the following:
* - nofile 65535
See the inline comments for more details on what that does and how to make it more restrictive if you prefer.
As root, run
$ ulimit -n 65535
and make sure you have no errors. To double check, run ulimit -n and make sure the response is 65535.
Ensure that PAM authentication is turned on for SSH, or else when you try to connect as a regular user, you won’t see the new limits. Edit /etc/ssh/sshd_config and make sure you have:
UsePAM yes
Restart SSH /sbin/service sshd restart if you made any changes.
Login as a regular user with a new SSH session & shell and run:
$ ulimit -n 65535
Run ulimit -n again to check and good luck!

Cannot Create New file: The device is not ready

I am Creating a new File using Java but am getting tis exception:

I have used this amny times before and I do not understand what's going on Because I am logged in as Administrator. Please Help.

The problem was the Path, which was not found because someone had renamed the drive letter from F to D. Sorry for not noticing that In time.

If this kind of error occurred in your net-beans while you deploying an app then open this path C:\Program Files\Apache Software Foundation\Apache Tomcat 8.0.3\conf\Catalina\localhost (it might be different as your tomcat installation dir). There is web.xml you should open it and check docBase="D:\xyz\web\target\web" is configured by proper project base directory or not.

deploy java app on Heroku launch.main error

I want to deploy a java appa on HEROKU. I am new to maven. I made all set up as per in the deploy a sample app to heroku (java+maven+ tomcat7)documentation.
and i made a bulid,It was successfull. But as soon i typed sh /target/bin/weapps i am getting the following error. Can anybody help me to sort out this issue.
Exception in thread "main" java.lang.NoClassDefFoundError: launch/Main

I had a similar problem, I (well, almost) solved it this way, just remove:
<packaging>war</packaging>
from pom.xml. I know this is not an ideal solution, but somehow the embedded tomcat plugin doesn't work with war packaging!

I don't have enough points to comment, but what article are you following? Can you link it?
Based on the error, I suspect your Main.java is not in src/main/java/launch. If you follow these instructions, I think you should be able to clear up the error:
http://devcenter.heroku.com/articles/create-a-java-web-application-using-embedded-tomcat
If that's the article you're following and you're still having trouble, it may ease the problems you're having if you simply clone the sample repo:
git clone git://github.com/heroku/devcenter-embedded-tomcat.git

Since you said you are new to maven, I think the reason of this error is that you simply put your *.java code under the root folder of the project, while you are rather expected to put it under ./src/main/java/
This should work for you. I experienced the same problem and figured this out.

This is probably dead, but in case it helps people of the future.
I was getting up and running with a java app on Heroku, using an Ubuntu machine for development - and got this same Exception in thread "main" java.lang.NoClassDefFoundError.
Double check that you're using the same java compiler version as your java sdk version.
type java -version & javac -version. Make sure they are the same version.
If not, you can fix this by reconfiguring your environment to use the same for both.
Assuming you have downloaded and installed the java version you want to use, type :
`sudo update-alternatives --config java`
You'll get a nice menu with options
Selection Path Priority Status

2 /usr/lib/jvm/jdk1.7.0/bin/java 1
Select the version you wish to use. Done.
Now try to build.
