tDotNetInstantiate error

shrikavi2008 — Sat, 30 Jan 2016 05:24:09 GMT

Hi,
I created a job with tDotNetInstantiate and tDotNetRow to call dll.
I have downloaded the janet-dll and placed in c:\windows\system32 as well as in java's bin directory.
But Getting error as below:

Hi,
Have you already configured the JDK path in Windows > Preferences > Java > Installed JRES?
Are you using 32 bit OS? janet-win32.dll for Windows 32-bit version and janet-win64.dll for Windows 64-bit version.
Please see the usage section in component reference: TalendHelpCenter:tDotNETInstantiate
Best regards
Sabrina

Hi Sabrina,
Thanks for you reply.
I placed both janet-win32.dll & janet-win64.dll in my 64 bit OS.
I placed above files in jre , JDK and system 32 folders. Still getting same error

Hi,

C:\Program Files (x86)\Java\jre1.8.0_66\bin\janet-win32.dll: A dynamic link library (DLL) initialization routine failed

Starting from version 6.0, Talend Studio requires a JDK installation instead of JRE only to build jobs, and you must configure the JDK path in Windows > Preferences > Java > Installed JRES.
Have you tried to place your janet-win64.dllm under C:\Program Files (x86)\Java\jdk1.8.0_66\bin to see if it works?
Feel free to report a ticket on Talend Support Portal for your subscription product so that we can give you a remote assistance through support cycle with priority.

I am having the same issue with the janet-win64.dll not being found.
I have placed it in the java\jdk\jre\bin and java\jdk\jre\lib as well as the system32 folder.

The error being given:
Exception in thread "main" java.lang.UnsatisfiedLinkError: no janet-win64 in java.library.path
at java.lang.ClassLoader.loadLibrary(Unknown Source)
at java.lang.Runtime.loadLibrary0(Unknown Source)

Has this been resolved?

Hi,
Did you unblock the DLL ?

Right-click on the DLL and click on the unblock button. Then try.
Thanks,

Hi rsimon1

Have you find solution ?

I created a C# dll and I try to use it in tDotNETInstantiate but I have this error :

java.lang.UnsatisfiedLinkError: C:\Program Files\Java\jre1.8.0_181\bin\janet-win64.dll: Can't find dependent libraries

I have try all solutions as i can find on the web but the error still (Put janet* in System32 or java jdk/jre folder. I have specified the path in properties...

Thank in advance for your time.
