Eclipse: ABAP communication layer is not configured... no sapjco3 in java.library.path

Question

Situation:

After downloading and installing Eclipse Luna.
Then Installing SAP Plugins: HANA, ABAP

Issue:

Error Message pops up when Eclipse starts:

ABAP communication layer is not configured properly. This might be caused by missing Microsoft Runtime DLLs VS2010. Consult the installation guide or download page for further details on how to install this component.

JCo initialization failed with java.lang.UnsatisfiedLinkError: no sapjco3 in java.libray.path

Answer 1

Solution 1:

Use Eclipse Mars since the error did not occur there.

Solution 2:

1. locate or get the sapjco3 file:

Use an appropriate search tool to check if sapjco3 file exists on your computer: I use unix-tools on windows and search for sapjo3 like this:

$ find /c -iname '*sapjco3*' 2> find-sapjco3.err.txt

Be aware that you need the unix-tool find for that command.
Be also aware that the windows search function may not find the file.

I found the file und this path:

C:/\Users\thorsten.niehues\.eclipse\org.eclipse.platform_4.5.0_1884348784_win32_win32_x86_64\configuration\org.eclipse.osgi\1060\0\.cp\lib\sapjco3.dll

In case the file is not located on your computer then you need the get it from the internet e.g. SAP Market Place (you need an S-User for the Marketplace)

2. Place the file in a path listed by java.library.path:

The paths can be determined by: System.out.println(System.getProperty("java.library.path"));
