Hello.

I use SAP Java Connector in my Java applet.

The applet works good, when I start it from IDE (I use Eclipse)

When I start from WEB-browser the applet doesnu2019t work.

Exception is

java.lang.ExceptionInInitializerError: JCO.classInitialize(): Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC'

By some note I could use the same version sapjco.jar, librfc32.dll, sapjcorfc.dll.

On sap.servise.com I couldnu2019t download that.

Can you help me with this problem. Or attach this 3 files.

Thank you for you attention.

Hi Alex,

I think you have to use JCo (Java connector) for this integration.

If possible you can try creating TCP/IP connection using SM59 but am not how exactly it works.
