Java io ioexception createfileexclusively

Fix: java.io.IOException: No such file or directory at java.io.UnixFileSystem.createFileExclusively(Native Method)

Error:
When importing, you see this error:

java.io.IOException: No such file or directory at java.io.UnixFileSystem.createFileExclusively(Native Method) at java.io.File.createNewFile(File.java:850) at edu.sdsc.grid.io.local.LocalFile.createNewFile(LocalFile.java:481) at org.dspace.storage.bitstore.BitstreamStorageManager.store(BitstreamStorageManager.java:325) at org.dspace.content.Bitstream.create(Bitstream.java:184) at org.dspace.content.Bundle.createBitstream(Bundle.java:355) at org.dspace.app.itemimport.ItemImport.processContentFileEntry(ItemImport.java:1045) at org.dspace.app.itemimport.ItemImport.processContentsFile(ItemImport.java:972) at org.dspace.app.itemimport.ItemImport.addItem(ItemImport.java:609) at org.dspace.app.itemimport.ItemImport.addItems(ItemImport.java:476) at org.dspace.app.itemimport.ItemImport.main(ItemImport.java:385) java.io.IOException: No such file or directory

If you are importing a collecting of items, it will often fail at different items.

Solution::
The normal issue that causes this is if you have been running the importer as a different user to the user that is running tomcat, or another user has been changing files (maybe running the filter-media cron job as root etc). Check that all of the directories under dspace/assetstore/ are owned by the correct user.

DSpace randomly selects a set of directories to put a new file in, and if one of these happens to not be owned by the same user you are running the importer as, then it won’t be able to write the file, and will stop. So check they are all owned by the correct user or that you have the correct permissions to write to them.

Because Dspace randomly chooses the directories to write the file to, the importer will stop and different places randomly.

You can fix the problem by using a command such as

chown -R user [dspace]/assetstore/

where user is the username that the assetstore should be owned by (often tomcat or dspace) and dspace is the location of your DSpace installation.

You’re trying to create files /hello.txt /test_file. The leading slash means you want to put them in the root of your file system. From the exception I see that you are using a Linux or UNIX file system (perhaps Mac OS even). The thing is, on Linux and UNIX systems, not every user can write to any location. Usually all users have only access to their own home folder, and the /tmp folder, with the exception of the root user who can do anything he wants on the system.

So, if you want to write to the root of the file system (which you really really really shouldn’t!) you’ll need to run your code as a user who has more rights. On Ubuntu you need to put sudo before the command, e.g. sudo java IOTest.File_1, and that will still fail if you’re not allowed to run sudo.

And could you please UseCodeTags next time?

Горячий, чтобы избавиться от java.io.Exception в java.io.WinNTFileSystem.createFileExclusively?

У меня в настоящее время проблема с тем, что я сталкиваюсь с исключением, которое я никогда раньше не видел, и почему я не знаю, как его обрабатывать. Я хочу создать файл в соответствии с заданными параметрами, но он не будет работать.

public static Path createFile(String destDir, String fileName) throws IOException < FileAccess.createDirectory( destDir); Path xpath = new Path( destDir + Path.SEPARATOR + fileName); if (! xpath.toFile().exists()) < xpath.toFile().createNewFile(); if(FileAccess.TRACE_FILE)Trace.println1("return xpath; > public static void createDirectory(String destDir) < Path dirpath = new Path(destDir); if (! dirpath.toFile().exists()) < dirpath.toFile().mkdir(); if(TRACE_FILE)Trace.println1("> 

java.io.IOException: The system cannot find the path specified at java.io.WinNTFileSystem.createFileExclusively(Native Method) at java.io.File.createNewFile(Unknown Source) [. ]

Проблема в том, что файл не может быть создан, если весь содержащийся путь уже существует — его ближайший родительский каталог и все родители над ним. Если у вас есть путь c:\Temp и поддиректории ниже него, и вы пытаетесь создать файл c:\Temp\SubDir\myfile.txt, это не сработает, потому что C:\Temp\SubDir не существовать. До

(Я не уверен, что mkdirs() требует только путь в объекте, а если это так, то измените эту новую строку на

В противном случае вместо этого вы создадите свое имя файла как подкаталог! Вы можете проверить, что правильно, проверив проводник Windows, чтобы узнать, какие каталоги он создал.)
