In My organization we are using a performance tracking tool named Dynatrace, Which says there are some errors when we open BIRT reports, i am not getting any idea from where this tool is hunting down this below issue. It looks like it is looking for some url http://localhost:631 on calling /SLE_BIRT/frameset and source of error is shown as org.eclipse.birt.report.soapengine.endpoint.BirtSoapBindingImpl. Method is getUpdatedObjects().
Is BIRT is trying to access some kind of Web Service from its library.
