sapjco3.dll: Can't find dependent libraries

[Former Member]

Hello

We have been using JCo2 for quite some time. Now we are going to use JCo3. I wrote a small Java application to run one RFC via JCo3. My application runs on Windows 7.

Error message:

Error getting the version of the native layer: java.lang.UnsatisfiedLinkError: C:\Program Files (x86)\JCo3\sapjco3.dll: Can't find dependent libraries

I can provide the complete stack trace if you want.

Does anybody know what are those dependent libraries?

Here is what I have done so far:

1) The installation.html included in the JCo3 download states 'Do not copy the sapjco3.dll...into...SysWOW64...'. So I created my own folder C:\Program Files (x86)\JCo3. (I have tried SysWOW as well. It makes no difference.) In my own folder I placed the sapjco3.jar and sapjco3.dll.

2) In Eclipse I added sapjco3.jar to the Java Build Path.

3) I installed the Microsoft Visual Studio 2005 C/C++ runtime libraries as described in note 684106 as per the instructions of the installation.html. I wish this would have added those dependent libraries.

4) At this point if I run my application I get a slightly different version of the error:

Error getting the version of the native layer: java.lang.UnsatisfiedLinkError: no sapjco3 in java.library.path

I resolved this problem by editing the 'Native library location' of the sapjco3.jar in Eclipse. After that I am stuck with the error stated above.

Thanks for any help...

Hi

I am not getting the error anymore. This is really cool. Looking forward to finishing my application.

Actually, this helped for me: http://scn.sap.com/thread/1018168

It points to the Microsoft Visual C++ 2010 Redistributable Package (x86). This instead of the 2005 version suggested in SAP note 684106 solved it for me.

Thanks for your help!

Hi,

I'm getting the same error, after installing the Microsoft Visual C++ 2010 Redistributable Package (x86) I continue getting the error "sapjco3.dll Can't find dependent libraries".

Please, anybody else can help me, any idea?

Thanks,

best regards

Solved!

Finally the problem was the version of the SAP Java connector, in http://service.sap.com/connectors i can download the correct versión.

Best Regards.

Hi,

We resolved this by adding the Visual Studio 2013 C/C++ runtime libraries. (Refer the java doc of sapjco 3.1.x version).

Thanks
