What is a DLL?

DLL stands for Dynamic Link Library, which serves as a set of instructions or functions for other programs to use. The purpose of a DLL file is to save disk space by providing quick access to code and data that are necessary for some applications to work. The benefit is that programs use a shared DLL instead of storing data in its files, thereby making your computer run faster.

Why did I get a JAVA.DLL error?

Most DLL files are included in Windows installation by default. When you install a program, it assumes that the necessary library is present on your computer. If a particular DLL file is corrupt or missing, an error message appears.

In most cases, DLL errors are caused by viruses or other malware. Occasionally, it’s because the DLL files are removed from the Windows Registry by accident, or no longer supported. Regardless, a DLL error is a sign that your computer is missing important data for applications to work.

# Resolving java.dll not found error

Steps to fix Could not find Java.dll error if you are using Oracle JDK.

If you are using Oracle JDK, Please follow the below steps:

Reinstall JDK and set system variable JAVA_HOME on your JDK. (e.g. C:\tools\jdk7)
And add JAVA_HOME variable to your PATH system variable
Type in command line

To verify whether your installation was done successfully.

Steps to fix Could not find Java.dll error if you are using OpenJDK

If you are using OpenJDK, this issue is a bug in OpenJDK 9 and is fixed in the latest releases. Please use the latest version of OpenJDK Java 9. You should be able to use Java 8 and Java 9 on the same client system without any issues. For clean install please refer Java Installation on Windows

Note:

If above steps fail to resolve the issues then this is most like an issue with environment variable path setup pointing to the correct version. Please make sure that there is no ambigous environment variable in the path.

Refer below links from Oracle for details:

More details about this Bug in OpenJDK —

Here is the summary of the proposed / implemented fix in OpenJDK:

Installer creates symlinks for java.exe and some other Java binaries in C:\ProgramData\Oracle\Java\javapath folder. This folder is added to system wide PATH variable. So when user types «java.exe -version», the symlink from C:\ProgramData\Oracle\Java\javapath folder is executed. Launcher calls GetJREPath() function from jdk/src/java.base/windows/native/libjli/java_md.c to get path to java.dll which is the JVM itself. GetJREPath() calls GetApplicationHome(). GetApplicationHome() calls GetModuleFileName() WIN API. It returns path to sysmlink, i.e. «C:\ProgramData\Oracle\Java\javapath\java.exe». Logic of GetJREPath() tries to find sibling java.dll. It fails as we don’t copy all bits from JRE bin folder of installed java to «C:\ProgramData\Oracle\Java\javapath» folder. GetJREPath() fallbacks to logic that tries to get path to installed JRE from the Registry. This trick woks for 8u. However, in 9 and Verona this fallback logic was dropped with JDK-8081824 fix. The proposed solution is to add extra processing of result of GetModuleFileName() call in GetApplicationHome(). The extra processing should detect in the running module is a symlink. It it is, GetApplicationHome() should return target of the symlink and not the path to symlink itself.

Please refer the below openjdk bugs for details.

How to fix Eclipse Error could not find java.dll

In this tutorial, we will go through the steps involved in how to fix the Eclipse error could not find java.dll. Eclipse installation depends on clean Java install on the machine. This error is due to corrupt java install on the machine.

Eclipse Error during the launch

Error: opening registry key ‘Software\JavaSoft\Java Runtime Environment’
Error: could not find java.dll
Error: Could not find Java SE Runtime Environment.

Root Cause: Java Corrupt Install

Fix for this error is to identify the corrupt Java install and reinstall it on the machine. In case of multiple Java installations, remove the corrupt install from the PATH variable.

Open a command shell and issue the following command:

>java -version
Error: opening registry key ‘Software\JavaSoft\Java Runtime Environment’
Error: could not find java.dll
Error: Could not find Java SE Runtime Environment.

Multiple Java Installs

Check the PATH variable to check if we have added multiple Java install paths. This error could be due to one of the corrupt Java install that has been specified in the PATH.

In this case, we need to identify the corrupt install and remove the corrupt Java install path from the environment variable.

Check Environment variables

To check JAVA_HOME on Windows:

>echo %JAVA_HOME%
C:\Program Files\Java\jdk1.8.0_121

To check PATH variable on Windows:

>echo %PATH% C:\oraclexe\app\oracle\product\11.2.0\server\bin;C:\ProgramData\Oracle\Java\ javapath;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem; C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\ ATI Technologies\ATI.ACE\Core-Static;C:\maven\bin;C:\Program Files\ Java\jdk1.8.0_121\bin;C:\Program Files (x86)\Silverfrost\FTN95; C:\Program Files\MATLAB\R2017b\bin;C:\codeblocks\MinGW\bin; C:\Program Files\MySql\bin;C:\WINDOWS\System32\OpenSSH\; C:\Program Files (x86)\Java\jdk1.8.0\db\bin;C:\Program Files\MongoDB \Server\4.0\bin;C:\ffmpeg\bin;C:\Python27;C:\Users\vani\AppData\Local \Android\Sdk\platform-tools;C:\Users\vani\AppData\Local\Microsoft\WindowsApps; C:\Fortran\g95\bin;C:\sqlite

In this case, there are multiple Java installs, and any could be corrupted or removed.

C:\Program Files (x86)\Java\jdk1.8.0\db\bin

The Oracle product that was removed from the machine still had it pointed in the PATH variable. Removing the entry from the PATH fixed the problem.
