I have this class initialiser:
System.setProperty("java.library.path", "C:\\Users\\lucas\\Desktop\\libraries");
System.loadLibrary("libTTARCHHelper");
TTARCH_LIBRARY=(TtarchLibrary)Native.loadLibrary(TtarchLibrary.class);
And the DLL is located at C:\\Users\\lucas\\Desktop\\libraries\\libTTARCHHelper.dll
If I run this in Eclipse I get 'The specified module could not be found' and if I run it as a JAR I get 'no libTTARCHHelper in java.library.path'.
How do I fix these? I even tried putting the DLL in a folder in the PATH environment variable.

So it looks like it doesnt find it , It throws a
java.lang.UnsatisfiedLinkError: The specified module could not be found.
I found the problem, the DLLs were for the wrong bit. Eclipse runs on 64 and the JAR uses the 32bit JVM. I downloaded the 32 bit dlls too and now it works when I run the JAR. However the 64 bit dlls in Eclipse keep throwing the module exception above
JNA will look for libraries at locations in the jna.library.path environment variable.
One option is to specify it as a command line option in Eclipse's run configuration. In the Run menu, select Run Configuration. Go to the (x)=Arguments tab. Add this in the VM arguments field:
-Djna.library.path=C:\Users\lucas\Desktop\libraries
You can also programmatically set it in your code before attempting to load the DLL:
System.setProperty("jna.library.path", "C:\\Users\\lucas\\Desktop\\libraries");
As you later indicated with the debug log, it may be finding the DLL but failing to open it. Possible reasons for this can be:
The DLL is runtime-dependent on another DLL on your system that's not in the appropriate path(s). A common one is the Visual C++ Distributable.
You may need to consult the DLL documentation for more information. You can sometimes use Process Monitor from the SysInternals library to try to see what it's opening.
Having a duplicate/incompatible version of a dependent DLL as above
Running a 64-bit JVM and trying to open a DLL that's not 64-bit compatible, or vice-versa
Your Java program may not have permission to read the directory where your library is located
To help diagnose the problem, look at the full stack trace. While the most recent error message may not be relevant (file not found in a "backup" search) if you look down the trace you may see multiple suppressed exceptions from earlier attempts to open a DLL which may give you more informative debugging information.

This was a well known error that was caused by some incompatibility issues between TOMCAT 7 & JDK <= 6.
In my case I'm working with this configurations:
Server number: 8.0.9.0
Server version: Apache Tomcat/8.0.9

JVM Version: 1.8.0_131-b11
Can anyone help me to solve this issue ?
I upgraded to tomcat 8.5 and everything works fine.
I am following google drive v3 api quickstart
tutorial
I don't want to use gradle for this application since is a group project.
I have downloaded the google drive v3 libraries.
I am using Intellij, and I have added all of the jar to the class path. All jars are imported successfully and the IDE doesn't give any error.
At run time I get a warning which from reading online seems to be a problem with Windows Compatibility.
I have downloaded the .json file with user ID and user secret and placed it in the same folder as the main
My code is the same as the one of the quickstart example:
The error i get is the following:

I don't Understand why I get this error or how I could correct it
I know that this is an old post, but I had almost the exact same stacktrace and couldn't find an answer. So, I'm posting in hopes that it will help those that come after me.
The issue appears to be related to file/directory permissions. As soon as I changed the filepath being used by the FileDataStoreFactory to a directory that my application had read/write permissions to, OAuth2 worked correctly. So, make sure that you are using a non-restricted filepath and that all of the directories have the correct ownership and permissions.

SEVERE: Failed to start Neo Server on port [7474]
How to clear this?
According to the documentation,
set the Neo4j configuration parameter "allow_store_upgrade=true" in your neo4j.properties or embedded configuration
Hope that helps.
In general with Neo4j, a database can be upgraded from a minor version to the next, e.g. 1.7 → 1.8, and 1.8 → 1.9, but you can not jump directly from 1.7 → 2.0.
You have two options:
upgrade to each minor version in succession setting the Neo4j configuration parameter "allow_store_upgrade=true" as in #Vidya's answer, or
re-import your data into the new 2.0 version of Neo4j.
I am getting this error while clicking on the neo4j.bat file in Windows. I tried other answers on stackoverflow but none of them is working. I set all variables in path JAVA_HOME & JRE_HOME. It says database incorrectly shutdown, performing recovery. And then console goes off. I have installed jdk 1.7 & jre7.

Most likely, you have an instance already running. Kill any Java processes and try again.
could you help me to change this command line to use it in a MacOS? the jar files will be on the desktop.
java -classpath jooq-2.0.0.jar;jooq-meta-2.0.0.jar;jooq-codegen-2.0.0.jar;mysql-connector-java-5.1.18-bin.jar;. org.jooq.util.GenerationTool /guestbook.xml
Thank you.

You can prepend the full path to each jar file (e.g. ~/Desktop/), and you also need to replace the windows classpath separator (semicolon, ';'), with the UNIX/MAC separator (colon, ':'). For example:
java -classpath ~/Desktop/jooq-2.0.0.jar:~/Desktop/jooq-meta-2.0.0.jar:~/Desktop/jooq-codegen-2.0.0.jar:~/Desktop/mysql-connector-java-5.1.18-bin.jar:. org.jooq.util.GenerationTool /guestbook.xml

The ':.' after the last jar file is required.
Thank you.
