Sapjco3.dll cant find dependent libraries

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...

"Hello, I have just installed JCO 3 on my laptop. I have download the latest version of JAVA from sun.com. Java functions correctly and can compile a simple JAVA file. Though when I check the JCO it fails to find the library when using the sapjco3.jar file and java -jar {sapjco-install-path}/sapjco3.jar. Details of error output are below: C:Documents and Settingswnash>java -jar c:tempsapjco-install-pathsapjco3.jar java.lang.UnsatisfiedLinkError: C:tempsapjco-install-pathsapjco3.dll: This ap plication has failed to start because the application configuration is incorrect .

I did a further review into "UnsatisfiedLinkError" and downloaded Dependency Walker program and found that I was missing two DLL files. Which I have put into C:WindowsSystem32, msvcr80,dll and msjava.dll. Based on other BLOG entries I have also downloaded the C++ 2008 vcredist_x86, as it seems JCO3 needs some special C++ libaries. I have also installed SAPGui 7.10 with Patch 15. Further, through the Dependency Walker program I also find that MPR.dll is missing a function, but other BLOGs mention it is not issue if the program initiates the dll. Has anybody had this same issue or can offer any advice. Basically all I want to do is confirm that we can change a legacy JAVA program so it can post sales orders into SAP. Kind Regards and Thanks Waza"
