Read in From a File Specified in the Command Line at Run Time

Recently I was trying to run the Apache Tomcat server from the control prompt to examination my Java web application on localhost, merely to observe the "The system cannot find the path specified" fault in command prompt. I oasis't seen this error earlier and then I was wondering whether tomcat is throwing or something is wrong with my system'due south PATH environs variable.  In lodge to outset the tomcat server, I was running the catalina.bat file as tomcat/bin/catalina.bat start and it wasn't starting the Tomcat at all, instead, it was keep throwing "The system cannot find the path specified." error as shown below:

C:\apache-tomcat-          7.0          .73\bin>catalina.bat          first          The system cannot          discover          the path specified. The organization cannot          find          the path specified. The arrangement cannot          notice          the path specified.

This really gives me hint that it's not the Tomcat only something is really incorrect with the PATH environs variable, simply what could be wrong? What does this error mean? and nearly importantly how to solve this mistake?

Cause of "The system cannot find the path specified." Error

Information technology seems this error occurs when you have invalid paths in your PATH surroundings variable e.yard. directories which don't exist anymore. To discover out if that'south the case just run following command in your DOS command prompt:

C:\apache-tomcat-          7.0          .73\bin>echo          %PATH%          C:\Windows\system32;C:\Windows;C:\Windows\System32\WindowsPowerShell\v1.0\; The system cannot          find          the path specified. The system cannot          find          the path specified. The system cannot          notice          the path specified.

Y'all tin see that later printing some paths, the command prompt is throwing "The system cannot find the path specified." error again, which means it has nothing to do with Tomcat or Catalina merely just with the PATH environment variable. In that location are some directories in the PATH which organisation is not able to resolve or find, hence it is throwing "The system cannot discover the path specified." error.

To be honest, the error bulletin makes sense if you read it, merely nosotros are so used to panic when we encounter the error, we don't try to understand the fault bulletin in first place. Now that, we take tried printing the value of PATH environment variable and seeing the message after few valid PATH, it all of a sudden starts making more sense.

This error is cipher to exercise with Tomcat, it tin come while running any program/application from command prompt or even when a program trying to use the PATH environment variable.

The solution of "The system cannot find the path specified." Error

Now that yous know the cause of this error is invalid directories and path in the PATH environment variable, you can easily solve this problem by finding and removing those invalid path entries which system is not able to establish.

Btw, finding invalid path can be a problem too if y'all have several directories listed in PATH environs variable. In order to check every path is correct, you need to split up the whole PATH String by semicolon and bank check if they are correct by copying and opening a directory in command prompt. This could be troublesome but it is the sure curt style to find all invalid path in your PATH environment variable.

Can we do better? is there a way to omit some of the valid paths? Well, if you lot have paid close attention to the output of echo %PATH% control, you see it printed a couple of directories earlier throwing the "The arrangement cannot find the path specified." error, which ways they are valid, so we should start the search from the signal point you see the mistake.

For case, in our case, the last valid path in the output above was "C:\Windows\System32\WindowsPowerShell\v1.0\;", so adjacent path must exist invalid. We tin confirm that by copying that path and opening from the control prompt by only copy pasting it on run window and hitting enter.

If information technology opens a directory then it's a valid path, otherwise, run window will tell it's an invalid path. The next step is to right or remove that path and run the echo %PATH% again. At this bespeak, you will run across the mistake when the system will hit the side by side invalid PATH, just repeat the process i.e. copy the invalid path by copying path after last valid path printed past echo %PATH% command and open that directory past using run control window or file explorer. If it's valid so it volition open a directory otherwise you come across the error, something like path doesn't be.

Repeat the steps until the error completely goes aways, at this time, all the paths in your PATH environment variable is valid and yous are gear up to run your plan from command prompt over again e.k. Coffee, Tomcat, NetBeans or anything else.

Btw, if you are wondering how to meet the value of PATH environs variable in Windows 8 or Windows x, you lot tin can follow these steps to copy the PATH String and edit information technology to correct or remove invalid entries in PATH environment variables.

1. From your desktop, rick-click "My Computer" and click "Backdrop"
2. In the System Properties window, click on the Advanced tab.
3. In the Advanced section, click the Environment Variables push.
4. In the Environment Variables window, highlight the Path variable in the Systems Variable section and click the Edit button.

Hither you can copy the value of PATH surroundings variable then y'all can search for concluding valid path e.g. "C:\Windows\System32\WindowsPowerShell\v1.0\;", then next path is your invalid PATH. Verify that by opening the directory using run command window or file explorer, if it's valid either right it or remove it and then salvage and open up a new command prompt to try again past running echo %PATH%.

If it throws "The system cannot find the path specified." error over again means you have some more than invalid paths in PATH environment variable. Simply go along correcting or removing them until your PATH is printed completely by echo %PATH%. At this indicate, your PATH has only valid entries and yous can tomcat or Coffee from the command line.

In my instance, though the root cause was nonetheless invalid path in PATH environment variable, the reason of being invalid was quite interesting. My system PATH surround variable has sub-directories with an ampersand (&) grapheme on it due east.m. C:\Program Files (x86)\A & B\bin. When I re-create pasted and open up the directory from the file explorer or run window it was managed to open the directory but when I put the same path in PATH environment variable it was throwing the "The organisation cannot notice the path specified." mistake.

I tried to escape & with backslash \ it didn't piece of work and then I tried to put single quote around A & B e.m. 'A & B', that didn't piece of work too, finally I removed the directory from PATH because it wasn't really needed and boom the mistake "The system cannot find the path specified." was gone. Now the full path is printed when I type the path or echo %PATH% in control prompt. Then, that resolved my problem.

Simply retrieve that every time you brand a change on PATH or Path surround variable under Organisation Properties department, you must open a new command prompt window, don't run the PATH or echo %PATH% on old command prompt window because information technology volition have onetime value of organization properties. The new, updated value of PATH volition only be available on new command prompt window.

Important points

one. The root cause of "The system cannot find the path specified." is an invalid path in PATH environs variable.

two. The name of the PATH environment variable can be Path or path likewise.

3. You should utilize the value of the PATH surroundings variable from System Properties Window in Advanced Settings, Environment Variables.

4. Watch out for & character in PATH, it's invalid and cause "The system cannot find the path specified.", remove them from PATH.

5. To discover the invalid path, just type the path or echo %PATH% in the control prompt and see where information technology is declining to display the directory path. That's your invalid entry. Notice out what is wrong and and so correct information technology or remove it from PATH.

That'due south all about how to solve "The organization cannot find the path specified." error while running the program from the command prompt. The root crusade of this fault is invalid directories, sub-directories in the PATH surround variable, just remove them and the error will be solved. When searching for invalid directories, look where the path is declining to display directory proper name, when you blazon the path or echo %PATH% in command prompt. Sentinel out for special characters like & in PATH, fifty-fifty though run window tin can open such path, it seems they are not valid for the PATH environment variable.
