How to excute java file from remote desktop(mstsc) - cmd

I logged into my remote desktop location from cmd by mstsc command. Made some changes in java file and saved it. But I am not sure how can I execute the java file from remote location. Can someone help me out.
Thanks and Regards,
Sm.Aslam.

I assume that you mean an uncompiled .java file. In that case, it is as easy as typing the following in Command Prompt:
javac file.java
Note that this requires Java to be installed on the remote computer. If this is not the case, you will have to install it.

Alias to open file on Windows using CygWin

I have a windows machine with CygWin installed on it. I do not hold any admin privileges, so, forget about changing environment variables which apply to all user and etc...
Scenario:
When I execute CygWin and type the following command to execute Maven, it works perfectly:
/cygdrive/c/maven/apache-maven-3.5.0/bin/mvn
However, when I create the file .profile as below:
alias mvn="cygdrive/c/maven/apache-maven-3.5.0/bin/mvn"
After restarting CygWing and executing the command "mvn", the following message is sent: No such file or directory.
Any suggestions?
Thanks in advance.
For any of you who may have the same problem, the way I solved this was basically adding a "sh" at the beginning of the command:
elias mvn="sh /cygdrive/c/maven/apache-maven-3.5.0/bin/mvn"
Cheers.

Installing and starting the H2 database on Ubuntu

I would like to use the H2 database on Ubuntu 12.10, and went to the website and got the platform independent install file.
The installation instructions are quite literally, "To install the software, run the installer or unzip it to a directory of your choice."
I'm not a Linux novice, so I've used many of the usual install procedures before, but I have no idea what I am supposed to do here. There are no configure or makefiles that I can find, and the documentation doesn't mention anything, and there I can't find anything using google.
I don't know if I am missing something obvious. Can anybody help please?
A shell script to start the H2 server and browser GUI is included. I don't have Ubuntu right now, but the steps should be:
Download the H2 zip file (for example h2-2013-07-28.zip).
Open a terminal window
And then run:
cd <download directory>
unzip h2*.zip
cd h2/bin
chmod +x h2.sh
./h2.sh
This should start the H2 server tool and open a browser window that lets you connect to a database.
The content of the h2.sh script is relatively simple, it is:
#!/bin/sh
dir=$(dirname "$0")
java -cp "$dir/h2-1.3.173.jar:$H2DRIVERS:$CLASSPATH" org.h2.tools.Console "$#"
What you can also do is double click the h2*.jar file (if double click is configured to start java), or run this on a command line:
java -jar h2-1.3.173.jar
this bash script start the server:
#!/bin/bash
java -cp h2*.jar org.h2.tools.Server
you need the h2-version.jar in the current directory as well
Download h2 from here http://www.h2database.com/h2-2015-01-16.zip, then once the download has completed, unzip in home directory and run the following:
cd (directory path ).
cd h2/bin.
chmod +x h2.sh.
./h2.sh.
If you're using Maven to download h2 database, then try to find out where does it saves (~/.m2/repository/com/h2database/h2/.../h2-version.jar). Since h2 dependency has all downloaded for you, then you just doubleclick on jar file (the web browser should open h2 GUI or look for h2 icon on system tray). And yes, GUI is the same as Standalone package has.
Update: as long as icon displays on tray - h2 will be launched. To disable it - right mouse click -> Exit

Uninstalling IBM WebSphere

I am uninstalling WebSphere from my drive E by using IBM installation Manager, during uninstallation it gives me the following error:
"E:\Program Files\IBM\WebSphere\AppServer\bin\clearClassCache.bat" not found"
I have searched and found that the location of clearClassCache.bat file is:
"E:\Program Files\IBM\WebSphere\AppServer\profiles\AppSrv01\bin"
Should i copy the file from AppSrv01\bin to AppServer\bin and retry uninstallation? Or is there any other solution to this problem?
Scripts under AppServer\profiles\AppSrv01\bin should also be under AppServer\bin, but the copy under profiles is often (always?) modified to be profile-specific. So I doubt that copying it will work for you.
That specific script is under my AppServer\bin, so it seems it's been removed in your case. Possibly from the earlier part of the uninstallation.
Kinda an old question but here it goes.
Uninstall script is in <application_server>\uninstall folder. Not sure what is called under Windows but on Linux it is <application_server>\uninstall\uninstall ( yes script has the same name as folder)

How to resolve the error "Unable to access jarfile ApacheJMeter.jar errorlevel=1" while initiating Jmeter?

Download Jmeter and execute the batch file (Jmeter\apache-jmeter-2.6\bin\jmeter.bat).
We get the error message in the console:
Unable to access jarfile ApacheJMeter.jar errorlevel=1
Kindly help me to resolve the problem.
Try downloading apache-jmeter-2.6.zip from http://www.apache.org/dist/jmeter/binaries/
This contains the proper ApacheJMeter.jar that is needed to initiate.
Go to bin folder in the command prompt and try java -jar ApacheJMeter.jar if the download is correct this should open the GUI.
Edit on 23/08/2018:
The correct answer as of current modern JMeter versions is https://stackoverflow.com/a/51973791/460802
I got this error today because the "Source" is missing the ApacheJmeter.jar. I downloaded it again from "Binaries" and everything works as expected.
JMeter should be started using :
jmeter/bin/jmeter.sh for Linux
jmeter/bin/jmeter.bat for windows
this will ensure correct property files are read and necessary jars in lib are loaded.
any other method will expose you to a lot of trouble.
the most upvoted answer is wrong !
See 1.4 Running JMeter in reference documentation :
https://jmeter.apache.org/usermanual/get-started.html
If you'd like to learn more about JMeter and performance testing this book can help you.
I'm running JMeter 2.8 (Windows 7) and received a message similar to that in the original post:
C:\>jmeter
Error: Unable to access jarfile C:\local\software\jMeter\apache-jmeter-2.8\binApacheJMeter.jar
errorlevel=1
Press any key to continue . . .
I'd created a Windows environment variable JMETER_BIN and set it to the JMeter path which I could see contained ApacheJMeter.jar (so it wasn't a question that the jar was missing).
I should have noticed at the time this portion of the error: "binApacheJMeter.jar"
When I went to the jmeter.bat file to troubleshoot, I noticed this line:
%JM_START% %JM_LAUNCH% %ARGS% %JVM_ARGS% -jar "%JMETER_BIN%ApacheJMeter.jar" %JMETER_CMD_LINE_ARGS%
and that caused me to revisit the "binApacheJMeter.jar" portion of the error.
What was happening was that the batch file was requiring a trailing slash on the end of the path in the JMETER_BIN environment variable to correctly specify the location of the .jar.
Once I corrected my environment variable, adding the trailing slash, all was wonderful.
YMMV, but this worked for me.
If you'll go through these steps:
In the Terminal type brew install jmeter and hit Enter
When it'll be done type jmeter and hit Enter again
You won't have to solve any kind of issue.
Don't thank 😀
I faced with the same error, when i downloaded the Jmeter Source, and it got fixed once i downloaded Jmeter Binary. Please watch this video.
navigate to the url http://jmeter.apache.org/download_jmeter.cgi-->download apache-jmeter-2.11.zip, which is under binaries.
this error is occurring since Apache jmeter.jar is missing in bin folder
If you are using linux and faced such problem during creating link, try to change jar file path of original jmeter file.
+ java -server -XX:+HeapDumpOnOutOfMemoryError -Xms512m -Xmx512m -XX:NewSize=128m -XX:MaxNewSize=128m -XX:MaxTenuringThreshold=2 -XX:PermSize=64m -XX:MaxPermSize=128m -XX:+CMSClassUnloadingEnabled -jar ./ApacheJMeter.jar -help
Change to:
java $ARGS $JVM_ARGS -jar "/opt/apache-jmeter-2.11/bin/ApacheJMeter.jar" "$#"
Try to use updated JMeter version which is JMeter 3.0 now.
I had moved the apache jmeter folder to c:, open cmd with admin grant and execute jmater.bat.
This solved the problem for me.
This error could also happen because of version mismatch of jmeter and java. As jmeter versions supports different java versions as below.
Download the zip accordingly and you are good to go.
For people still getting the issue.
I face same problem and seems some .jar file missing.
so try tar -xf apache-jmeter-5.2.1.tgz in the console rather than just right click unzip. And also, try binary package if source package still has an issue.
this solve my issue (I am using ubuntu)
For window if you download scr folder say apache-jmeter-5.3_src then you won't find ApacheJMeter.jar file insider bin folder.One might have downloaded zip file under source section. Form this link download zip file under binaries section and click on ApacheJMeter.jar from bin folder https://jmeter.apache.org/download_jmeter.cgi
When we download the binary of apache-jmeter-x.x.tgz, where x could be any version of apache Jmeter. ApacheJMeter.jar must present inside apache-jmeter-x/bin folder , if it is not present somewhere your package not downloaded properly. Cause could be slow internet, or improper shutdown
Download package again and make sure ApacheJMeter.jar present in apache-jmeter-x/bin folder. Once it is present hit sh jemeter.sh
This issue will come if you download the source from the below URL :
https://jmeter.apache.org/download_jmeter.cgi
Solution :
Always download :
Apache JMeter 5.5 (Requires Java 8+)
Binaries
apache-jmeter-5.5.tgz sha512 pgp
apache-jmeter-5.5.zip sha512 pgp --- > This one
worked for me

Programming on a remote machine [Eclipse - ruby]

Has someone used any add-on on eclipse to develop on a remote machine ?
I am having to ssh through the terminal and copy paste the eclipse code
to run it on a remote host that has the necessary permissions for the
task. I am wondering if I can do that on eclipse from my ubuntu desktop
Thanks!
Edit:
https://help.ubuntu.com/community/SSHFS suggested by Shawn Bower works as far as the OS is concerned
Q] Unfortunately eclipse can open the script on remote mounted FS, however it doesnt show up in the Script explorer or in run Configurations. "Invalid working directory"
Q] Is there a way to sudo su when I am using SSHFS.
To give a perspective:
Normally I log into the remote user as myself#remote and then sudo su - powerUser and then use that to run my ruby scripts. Unfortunately I do not have the pswd for powerUser.
So now though I can edit the scripts on eclipse after using SSHFS , I still cant run them as powerUSer.
Thanks !
Have you looked into using sshfs? https://help.ubuntu.com/community/SSHFS. It will allow you to mount the remote file system so it acts as a local filesystem. Then you can just point eclipse at the local path and edit away. I use this for a bunch of sites.
