java.lang.UnsatisfiedLinkError: E:\SAP\sapjco3.dll

[Former Member]

Hi All,

I am new to SAP Netweaver.

I am trying to write a standalone java program to execute few RFMs. I am using JCO 3.0. The program works on my laptop. But when I deploy the same program to the server, the dll does not work. I get the following error.

java.lang.UnsatisfiedLinkError: E:\SAP\sapjco3.dll:

This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem

I am not sure what reinstalling means. We just have to extract the jar and dll files and put them in classpath and path.

The server OS is Windows 2003 Server.

Am I missing something?

Thanks,

Daya

I too faced the same issue.

Please follow the pre-requisites. Dont install any advanced versions.

Eclipse Platform2020-03 (4.15)Operating System

• Windows 7/10, or
• Apple Mac OS X 10.13 or higher

Java Runtime^*JRE version 8 or 11 (64-Bit)SAP GUI

• For Windows OS: SAP GUI for Windows 7.50
• For Apple Mac or Linux OS: SAP GUI for Java 7.50

SAP GUI is not required to work with the SAP Cloud Platform ABAP Environment.Microsoft VC Runtime

For Windows OS: Microsoft Visual C++ 2013 (x64) for communication with the back-end system is required.

I followed the same. Now my issue resolved.

This thread is ancient but it crops up in all google searches so I thought I would post a solution anyway.

I had exactly the same problem and tried all of the above without success.  The solution in my case was to make sure the JVM and sapjco3.dll were the for the same platform.  I had the 64 bit JCO3 running with 32 bit JVM.  I changed and installed the 32 bit JCO3 version.

Go to Start>Control Panel>Java to check JVM version.

If that doesn't work try these:

1. JCO 3 problems with Library - UnsatisfiedLinkError [SOLVED] - Toolbox for IT Groups

2. https://scn.sap.com/thread/11967

3. Error: sapJco3 load the Java library

Redistributable Package worked to me too. My Windows 7 distribution is based on 64x

Hi all,

I had the same problem today using sapjco3.dll on a Windows XP Professional system.

For me the link didn't work but the following containing the SP1 of the C++ 2005 package did:

Maybe this will help others, too.

Hello

To help yourself, install SAPGUI 710 on the machine where you have the problem, and the error will be disappeared.

I know, that this is not an explanation but a good medicine

I don't really know how dll work and i don't want to break anything. Any hint?

Thanks

Lucie

Hi John,

Can you please tell, how to change the version in the manifest?

Also, did you try running some JCo code after you got rid of the error?

Thanks,

I get the same error with version3 (version 2 works).

I searched for the error with "Dependency Walker" and here is what I found:

Is the dll broken?

"Diese Anwendung konnte nicht gestartet werden, weil die Anwenungskonfiguration nicht korrekt ist. Zur Problembehebung sollten Sie die Anwendung neu installieren" is german and is the translation of

"This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem"

SOLVED:

The problem is a wrong version of "Microsoft.VC80.CRT" (msvcr80.dll) in e.g. Windows XP.

The manifest of sapjco3.dll demands version 8.0.50727.762 whereas Windows XP has only version 8.00.50727.163.

<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
  <dependency>
    <dependentAssembly>
      <assemblyIdentity type="win32" name="Microsoft.VC80.CRT" version="8.0.50727.762" processorArchitecture="x86" publicKeyToken="1fc8b3b9a1e18e3b"></assemblyIdentity>
    </dependentAssembly>
  </dependency>
</assembly>

Because of a newer version in Windows Vista there is no problem with sapjco3.dll in Vista.

(To test I changed the version in the manifest and then there was no java.lang.UnsatisfiedLinkError in Windows XP, too.)

Hi,

I'm getting the same problem, can you help me solve this problem?

Where can I change the Manifest of sapjco3.dll?

Thanks in advance

[Former Member]

The manifest is part of the dll.

You can edit the header with e.g. PE-Explorer (http://www.heaventools.com/) (or even any HexEditor).

After you change the minimum version everything seems to work fine (I successfully called a remote function).

A cleaner solution I did is to make a "side-by-side" (C:\WINDOWS\WinSxS) install of the newer dlls which are required.

Hi ,

Hi

You said it worked on you laptop, have you checked the authorizations for the you programs on the server , does it have the permission to execute it on the server. If it's Dev server try adding it to the sidadm group.
