Definition
In Salesforce development, an open-source Java library (Web Service Connector) that generates Java stubs from Salesforce WSDL files, providing a client framework for making SOAP API calls to Salesforce from Java applications.
In plain English
“WSC (Web Service Connector) is an open-source Java library that generates Java stubs from Salesforce WSDL files. It provides a client framework for making SOAP API calls to Salesforce from Java applications.”
Worked example
Marlowe Cosmetics has a Java application managing wholesale buyer accounts that needs to read and write Salesforce data via SOAP API. The integration developer downloads the Salesforce Enterprise WSDL, runs the WSC (Web Service Connector) Java tool against it, and gets a generated set of Java client classes - typed wrappers for every Salesforce object and operation. Her Java code calls account.setName(...), connection.create(new Account[]{...}), and similar typed methods rather than building raw SOAP envelopes. WSC handles the SOAP serialization, session management, and error handling; the developer focuses on the integration's business logic.
Why WSC (Web Service Connector) matters
In Salesforce development, WSC (Web Service Connector) is an open-source Java library that generates Java stubs from Salesforce WSDL files, providing a client framework for making SOAP API calls from Java applications. It simplifies Java-based Salesforce integration by generating typed Java classes from WSDL definitions.
WSC is relevant for Java developers building SOAP-based integrations with Salesforce. Most modern integrations use REST APIs (with HTTP clients rather than WSC), so WSC is less common now than it was when SOAP was the primary Salesforce API. It remains useful for Java teams maintaining SOAP-based integrations.
How organizations use WSC (Web Service Connector)
Maintains legacy Java integrations using WSC while building new integrations with REST.
Teaches WSC as context for legacy Java integration patterns.
Uses REST APIs for new Java integration, reserving WSC for legacy SOAP.
