Talend: java.lang.UnsatisfiedLinkError: no sapjco3 at java.library.path

I have a jar and a dll in the Talend lib directory. Path and classpath are set. I also downloaded and installed the VC ++ 2005 sp 1 redistribution patch and the missing DLLs that are supplied by SAP. I tried to run this ETL job on a Windows 2003 machine and on an XP machine with the same result. Can anyone help me here.

First make sure you have the .jar file in \ lib \ java \ If you are on windows you should put the dll and sapjco3.jar in C: \ Windows \ system32 \ If you are using Linux you need to put the .so files in own way.

  • copy sapjco3.jar file to talend lib / java folder and make sure sapjco3.dll is in% PATH% (quick and dirty place in Windows \ system32 \)
  • check it by double clicking sapjco3.jar it should show jar location information and dll location


Common OS problems Talend and sapjco3: You need the 32 bit version if you are using 32 bit JAVA. 64-bit version if you have 64-bit Java.
