The integration framework supports queries from external systems. The external system sends an XML message to query the integration framework and the integration framework returns an XML message as a response to the query. You can execute a query for object structure and enterprise services by using HTTP, Java™ Remote Method Invocation (RMI), or a Simple Object Access Protocol (SOAP) request in a web service.
Support for XML queries is based on the system Query By Example (QBE) capability that is available from the List tab of most applications. XML-based queries provide the same query support that is provided in the applications except for attribute searches that are available in some system applications. Integration query time outs are controlled by the mxe.db.Query.Timeout system property.
