JCO error with client.getAttributes

[Former Member]

Hello,

I connect my Rich Client to Sap with JCO. After the connect I want read the attributes with JCO.client.getAttributes(). If I do that then I get this error message:

com.sap.mw.jco.JCO$Exception: (121) JCO_ERROR_NULL_HANDLE: Invalid rfc_handle = NULL encountered

at com.sap.mw.jco.rfc.MiddlewareRFC.nativeGetAttributes(Native Method)

at com.sap.mw.jco.rfc.MiddlewareRFC$Client.getAttributes(MiddlewareRFC.java:1206)

at com.sap.mw.jco.JCO$Client.getAttributes(JCO.java:2855)

What I do wrong? I hope you can help me.

Best Regards
