I have a new windows 10 machine. Tomcat throwing the error -
FileNotFoundException - Access Denied
while writing application log. I am able to create folders or save file in the same path but when i try to do that programmatic, its throwing the error
Access Denied
When i checked 'canWrite()' on the path its returning true.
canWrite:true
java.io.FileNotFoundException: C:\Users\<User>\logs (Access is denied)
I tried giving 'full control' to the folder but didn't help.
Any pointers ?
Thanks!
Reboot and retry (I have seen exact the same in a Windows Domain environment. After reboot it works.);
Is the tomcat started as a service, or as standalone app? Check the user who own the tomcat process;
If both failed, try to delete the log folder, to see if any other process locks the log folder;
At last, you can use process monitor (https://learn.microsoft.com/en-us/sysinternals/downloads/procmon) to drill into the internal data from windows, to see what really happens.

I run a Java Application by using Apache Tomcat 7.0. I want to write files to another ftp server. The ftp file path is saving in a text file (//192.168.100.3/ftp/Testing).
When I start tomcat from bin>>tomcat.exe, the file is really written to the Ftp server.
When I start tomcat from services.msc, the following error occurs: File not found exception : access is denied
Execute services.msc as an administrator.
I assume one of the invoked files is in a subdirectory of Program Files and thus needs special permissions to be run.
On a particular server (Windows 2012 server R2) I am having trouble creating a temp file. I get the following error everytime I try.
java.io.IOException: The system cannot find the path specified
at java.io.WinNTFileSystem.createFileExclusively(Native Method)
at java.io.File.createTempFile(Unknown Source)
etc..
The error happens everytime the following code is ran:
InputStream inputStream = portalBean.createPDF( sessionID, foCode );
Things I have tried
Changed the java.io.tmpdir variable on the fly. System.setProperty("java.io.tmpdir", "C:\\");
Added -Djava.io.tmpdir=c:\\temp to the webnetwork lax file to an unrestricted location.
I tried setting the webNetwork service to run as a specified user with rights to temp files e.g. the Administrator.
Made sure I have free disk space and I cleaned out the c:\windows\temp folder.
Made sure the tmp environment variables were set to their default values.
I also tried running the service from a command prompt which was opened with the Run As Administrator option.
And the IOException lingers still. I have another server running the same code without issue (Windows Server 2012).
Does anyone else have any Ideas of what else I can try to resolve this issue? And or any tips on how I can debug the issue more thoroughly to get a grasp of what is going on?
One tool you can use to debug this is process monitor from system internal tool kit. The step is: add a filter to only monitor your process (I think it is javaw.exe in your case), after the error happens, go through the file activities in the process monitor log, you can find how the process is finding files and which directories the process searched. If the process is searching in the wrong directory, you can find it from the log.
I just used this tool to figure out a JVM crash problem today.
Based on the description of your problem, I guess the path variable of the process is changed in the middle of your code, with another tool process explore you can view the path variable of the process, it might help.
Try and create instead a directory somewhere under your home directory:
final Path tmpdir = Paths.get(System.getProperty("user.home"), "tmp");
Files.createDirectories(tmpdir);
System.setProperty("java.io.tmpdir", tmpdir.toAbsolutePath().toString());
Then try and Files.createTempFile() in there.
Note that if Files.createDirectories() refers to an existing file which is not a directory, you'll get a FileAlreadyExistsException.
May be you can help me with this problem.
Profiler crashes with "Access denied" message, then i start it for any local application. In a logfile I found:

Application runs on the same JVM HotSpot 1.07.0_21 x32 (VisualVM from JDK 1.6 works fine), using just next options:
-client -Xmx1524M
Any suggestions?
UPD: OS is WindowsXP sp3 x32
Have you checked their troubleshooting section?
in particular:
Insufficient permissions for %TMP%\hsperfdata_username folder - make
sure you're able to create a file in the directory and eventually
update the permissions for full folder access. Alternatively you can
just re-create the folder which should automatically set the correct
access rights. See see this forums.sun.com thread for more details.
For me I got below error while creating the heap-dump:
[com.sun.tools.visualvm.attach.AttachModelImpl]: takeHeapDump java.io.IOException: Access is denied
I could manuallya access this folder %TMP%\hsperfdata_username.
Hence I thought of launching the visualVM in Administrator mode,It resolved the issue.
Thanks #Lorenzo for inputs.
i'm having the the post's title error when trying to write a file on a window folder , mounted on unix system. I've developed a web service which runs inside a Tomcat 6 on a linux os and need to write on a windows network folder. System administrators have mounted it on the Linux sever and have no problem to create and modify a file on it.
When i try to execute the posted code i get the following exception :
Permission denied
java.io.IOException: Permission denied
at java.io.UnixFileSystem.createFileExclusively(Native Method)
at java.io.File.createNewFile(File.java:850)
The weird thing is that it seems to be related to the File.createNewFile method on a network folder , in fact the service can write on local file system without problems, both on debug (the pc i use to develop the service) and a tomcat folder system administrators have provided me on the linux server. The file gets created but is empty and the log entry following the create method doesn't get printed. Moreover if i use a plain outputstream to create and write the file i've no problems.
I cannot find any explanation about the exception on the web. Since i'm not very experienced with java , i'd like to understand why i'm getting this error. Am i using it in the wrong way ? Is it a bug of the library ? Do i miss to pass some parameter ?
As stated , i've solved the problem using a plain outputstream, this is a question to improve my understanding of java.
FileOutputStream fos = null;
try{
log.info(String.format("file length: %s",streamAttach.length));
log.info(String.format("check File : %s",filename));
File f = new File(filename);
if(f.exists())
...
boolean done= f.createNewFile();//here comes the exception
//nothing of the following happens
if(!done)
throw new NWSException("error creating file");
log.info(String.format("file %s creato", nomeFile));
thank you in advance for any answer
I ran into this problem recently and found that java.io.File.createNewFile() actually requires the "Change Permissions" permission (you can find this entry under Security->Advanced when checking folder permissions). Without this it will create the file and then subsequently throw an IOException.
It's deceptive because you will still be able to create files on the folder when manually testing, however createNewFile() will still fail if it doesn't have this particular permission (presumably such that it can change the permissions on the file its creating).
If you are using Netapp that shares an NTFS (CIFS) style filesystem to Unix you could be experience "NFS is not allowed to change permissions on a file in an NTFS-style security volume." (TR-3490 page 16)
Options here are to change to a unix filesystem or set the cifs.ntfs_ignore_unix_security_ops flag to on for the file system which quiches the NFS permission error.
java.io.UnixFileSystem.createFileExclusively(Native Method) opens the file with the O_EXCL and 0666 umask so I would get a EACCES, which really was a NFS3RR_ACCES
open("/net/storage01-a/filer/myfile", O_RDWR|O_CREAT|O_EXCL, 0666) Err#13 EACCES
Also you can use OutputStream to create the file, that does not use O_EXCL it seemes
It definitely not Java specific problem. If this Unix folder is mapped to your windows try to open file explorer and create file in this directory. I believe that you will get permission denied too. In this case fix this problem or ask your system administrator to help you.
Good luck!
now i'm desparate. I feel like i'm turning round. when i believe solve something then i break something else.
started using this mac this week.In the process of setting up my environment i face some challenge.I got a maven project which uses cargo plugin to publish to tomcat working fine.for that i had to google to create the /etc/launchd.conf file.For some reasons web applications created in netbeans cannot publish to tomcat server i thought it was due to tomcat permission but when i set chmod 777 /Library/tomcat020
sh-3.2# ls -l /Library/tomcat6020
total 136
-rw-r--r--# 1 highjo admin 6148 Nov 4 16:03 .DS_Store i have this for file
drwxr-xr-x# 26 highjo admin 884 Nov 4 16:03 bin and this for folder
i was expecting to be rwxrwxrwx.that's the first problem.
second the first project in maven that was working is not any more.
showing
org.apache.maven.surefire.booter.SurefireExecutionException: Unable to create file for report: /myproject/target/surefire-reports/com.myproject.dao.hibernate.someDAOImplTest.txt (Permission denied); nested exception is java.io.FileNotFoundException: /myproject/target/surefire-reports/com.myproject.dao.hibernate.someDAOImplTest.txt (Permission denied); nested exception is org.apache.maven.surefire.report.ReporterException: Unable to create file for report: /myproject/target/surefire-reports/com.myproject.dao.hibernate.someDAOImplTest.txt (Permission denied); nested exception is java.io.FileNotFoundException: /myproject/target/surefire-reports/com.myproject.dao.hibernate.someDAOImplTest.txt (Permission denied)
same Exception and permission denied anytime i need to run a web app which is supposed to be published on tomcat.
Is Netbeans lacking privileges to access those files?I 'm running late to set up the developement environment.I need help! thanks for reading this
As for the chmod, you seem to be expecting recursive behavior (since you're looking at the permissions what's IN the directory that you chmod, rather than the directory itself). In that case, you should be using chmod -R.
You say chmod 777 /Library/tomcat020, but then ls /Library/tomcat6020 ( note extra 6 )
