java.io.FileNotFoundException on Properties FileInputStream in CMD

I'm loading a Property file with the following method:
private final String utitt=Paths.get(".").toAbsolutePath().normalize().toString();//
...
properties.load(new FileInputStream(utitt+"/beallitasok/lang.set"));
...
This works fine within NetBeans without problems, but the jar file fails in command prompt:
java.io.FileNotFoundException: C:\java\IKE\dist\beallitasok\lang.set
(A rendszer nem találja a megadott fájlt)

at IKE.IKE.(IKE.java:544)
at IKE.IKE.main(IKE.java:697)
I've copied the "beallitasok" directory there (to c:\java\IKE\dist in my case), so the file is actually there. I'm using some files to translate certain strings and save/read some settings. I've checked whether i'm just blind, so just opened the file with a "more C:\java\IKE\dist\beallitasok\lang.set" command and it works.
Where or how shall i search for a clue? I'm not a pro, so thanks for any help.
PS: (A rendszer nem találja a megadott fájlt) = The System can't find the specified file. Translated from the Hungarian language.

FileNotFoundException: path syntax wrong

I am trying to export my project as an executable jar file in eclipse.
My jar file looks like this:
\com
\de
\org
\res
I've got some xml files in the res folder and now I have some problems getting these files with the FileReader
java.io.FileNotFoundException: jar:file:\C:\Users\Patrick\Desktop\Brainwav3.jar!\res\de.xml (Die Syntax für den Dateinamen, Verzeichnisnamen oder die Datenträgerbezeichnung ist falsch)
at java.io.FileInputStream.open0(Native Method)

at java.io.FileReader.<init>(Unknown Source)
at de.brainwav3.language.LanguageHandler.load(LanguageHandler.java:98)
at de.brainwav3.core.Launch.main(Launch.java:24)
The path gets generated like this:
URL url = getClass().getResource("/res/de.xml");
FileReader reader = new FileReader(url.toString());
So I don't really have control over the path.
I resolved this problem with copying the required files next to the jar file and changing the url to another path but I want all ressources to be inside the jar file

Error connecting Java to SQL Anywhere database

I am trying to connect a java program to a database. I have sajdbc4.jar in the build path and it worked before, but now I keep getting this error when I try to make the connection:

Can someome please help me? Can't find anything abount this issue online.

For windows find this file in your computer:
dbjdbc12.dll
For linux find this file:
libdbjdbc12.so
Put the location of this file on the java.library.path either with a command line option:
java -Djava.library.path=DIRECTORYWITHDLL ...
or using System.setProperty in your code:
System.setProperty("java.library.path","DIRECTORYWITHDLL");

For Linux, you need to add the dbjdbc12.so to java.library.path using:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/some/path/that/contain/dbjdbc12.so
this is the same for dbjdbc16 also.
Since, sybase.jdbc4 driver need this file. Please refer- https://blogs.sap.com/2014/05/02/connecting-to-sql-anywhere-using-jdbc-2/#:~:text=jar%20is%20in%20the%20classpath,Connection%20con%20%3D%20DriverManager.
Similarly, for windows add dbjdbc12.dll file.

For SQL Anywhere 17 libdbjdbc17.so was not suffiecient, it was then complaning about the next file:
failed: java.lang.UnsatisfiedLinkError: /usr/local/tomcat/native-jni-lib/libdbjdbc17.so: libdbtasks17_r.so: cannot open shared object file: No such file or directory
So I ended up adding all files from the lib64 folder from the Database client (after I installed it on some other linux machine) to my tomcat lib path and it worked.

FileNotFoundException while trying to write an image using thread in java

I am trying to write an image using ImageIO.write() inside run() method of a thread in java. But it is throwing FileNotFoundException and not allowing me to write the image. It is showing stack trace as

Please suggest some solution. Thank You.

Run the Command Prompt or whatever IDE you are using as an Administrator and execute the program again. Else, change the path to a place when you have appropriate writing permissions.

It looks ike you have not the permission to write the file in C:\abc\pqr\

Java get resource InvalidJarIndexException

I have a class names test.java and another file "log4j.properties" in the same folder but following call
getClass().getResource("log4j.properties")
fails with
ms

sun.misc.InvalidJarIndexException: Invalid index

But getClass().getClassLoader().getResource("log4j.properties") works. What can be the reason?

The InvalidJarIndexException is normally caused by a corrupt INDEX.LIST file in the JAR. So check the JAR for any problems. See http://littletechsecrets.wordpress.com/2008/12/01/why-does-invalidjarindexexception-occur/
The different results you describe are probably related to Class.getResource() resolving a path relative to the classes package, and ClassLoader.getResource() resolving a path relative to the root. So getClass().getResource("/log4j.properties") might fix your problem.
