After upgrade 7.0 > 7.4 : inspection.wsil empty, no webservices listed

[Qualiture]

Hi all,

We are facing a rather strange but blocking issue after we upgraded our NetWeaver 7.0 environment to 7.4

When testing the Adobe Document Services, we found out they did not work.

As a first step, we checked the 'ConfigPort_Document' destination, but that was configured correctly. However, upon opening the containing <host>:<port>/inspection.wsil showed a shockingly empty WSIL except for the <wsil:inspection> header data...

When looking in wsnavigator, we found the total amount of 0 service endpoints, whereas we'd expect somewhere around 60+ or so...

In the logs we find traces like:

there is an error in publishing service definition : SOAPublicationObject{SOAObject{class='com.sap.esi.esp.lib.mass.entity.ServiceDefinition'soaObjectInfo=SOAObjectInfo

SOAObjectId

type = SERVICE_DEFINITION

local = sap.com~caf~eu~gp~model~ejb.com.sap.caf.eu.gp.model.gpws.uwl.GPWorkItemProviderVi

ns = sap.com/caf~eu~gp~model~eap

processingState = INITIAL

delete = false

(processingTraceId=null, processingLogId=null)

displayName=GPWorkItemProviderVi, description=GPWorkItemProviderVi

status=Active

systemObject=false, hiddenObject=false}'serviceRegistryStatus=UNKNOWN}

the SR returned : com.sap.esi.esp.lib.mm.config.exceptions.TechnicalException: com.sap.engine.interfaces.webservices.runtime.reverseproxy.WSReverseProxy

...for all the various services.

The recurring theme seems to boils down to a flakey WSReverseProxy class and or tc~esi~esp~srv_api.jar, but it might have an even deeper rootcause...

Any hints on why this behavior might happen and ultimately how we can solve it?

Any help will be much appreciated!

Eventually our issue got solved by implementing note 1616798 - ClassNotFoundException - WSReverseProxy

Hi Robin,

I am not sure but you  can check below sap note

1856845 - NullPointerException when publishing to central SR

It may help you.
