WebDynpro - SAP JCO. TypeNotFound Exception

[Former Member]

Hi,

In my WebDynpro application, the requirement is to connect the backend R/3, not by SLD, but by using SAP JCO Connectvity. So I created the proxy classes, JCO.Client parameters etc etc. While executing the application, an exception is throwing from the system. TypeNotFoundException.

The initial exception that caused the request to fail, was:

com.sap.tc.webdynpro.services.exceptions.TypeNotFoundException: type java:com.sap.mw.jco.JCO.Client not found

at com.sap.tc.webdynpro.services.datatypes.core.DataTypeBroker.getDataType(DataTypeBroker.java:224)

at com.sap.tc.webdynpro.progmodel.context.DataAttributeInfo.init(DataAttributeInfo.java:318)

at com.sap.tc.webdynpro.progmodel.context.NodeInfo.initUnmappedAttributes(NodeInfo.java:687)

at com.sap.tc.webdynpro.progmodel.context.DataNodeInfo.doInit(DataNodeInfo.java:238)

at com.sap.tc.webdynpro.progmodel.context.NodeInfo.init(NodeInfo.java:671)

I already setup the classpath and buildpath accordingly.

Anybody knows the solution, please help me.

Thanks and Regards,

Hi Vipindas,

You can try the following steps to get rid of this exception

1. Undeploy the application

2. Remove the JCO

3. Recreate the JCO

4. Restart the server and deploy the application

Thanks & Regards

did you set RunTime dependency for all used DCc?
