This online help provides reference documentation for the 3.5 WSDL that is available in the IBM® FileNet® P8 Platform 4.5 release and beyond.
In Content Engine 4.0.x, Content Engine Web Service (CEWS) applications were limited to using the 3.5 WSDL, which supported Microsoft® Visual Studio® .NET 2003 with Web Services Enhancements (WSE) 2.0 SP2 and IBM Rational Application Developer® 6.0. The 3.5 WSDL endpoints also supported DIME attachments and SOAP with inline, Base64 encoding for uploading and retrieving content data. Beginning in the 4.5 release, you have the choice of creating a CEWS client application using either the 3.5 WSDL or the 4.0 WSDL. The 4.0 WSDL supports Microsoft Visual Studio 2005 with WSE 3.0 (incompatible with DIME) and its endpoints also support Message Transmission Optimization Mechanism (MTOM) and SOAP with inline, Base64 encoding for uploading and retrieving content data. The 4.0 WSDL does not support IBM Rational Application Developer Java™ clients. Documentation for Content Engine Web Service for the 4.0 WSDL is installed as part of the IBM FileNet P8 documentation installation.
New applications being written for the 4.5 environment and beyond should use the Content Engine 4.x Java API, or Content Engine 4.x .NET API. Although these APIs are layered upon CEWS, they offer much better ease of use and supportability than using the CEWS interface directly. The 3.5 WSDL continues to be supported in the 4.5 release going forward primarily to allow you to use existing CEWS 3.5.x and 4.0.x applications that you do not wish to upgrade (note, however, that some CEWS 3.5.x applications using the 3.5 WSDL might still need to be ported in order to run in a 4.5 environment). Starting with the 4.5 release, the 4.0 WSDL is supported primarily to allow you to upgrade existing CEWS 3.5.x applications so that they can take advantage of MTOM based attachments, and new web service application development frameworks.
Beginning with the 4.5 release, the use of the Direct Internet Message Encapsulation (DIME) standard to upload and retrieve content is deprecated; MTOM is now the preferred mechanism. Support for DIME attachments will be dropped in a future P8 release. Because DIME support is deprecated in this release, the DIMEAttachmentReference
and DIMEContent
elements in the 4.0 and 3.5 DIME endpoints are also deprecated. Therefore, you are encouraged to port existing 3.5.x or 4.0.x .NET client applications that use DIME for content upload and retrieval to use the 4.0 MTOM endpoint.
For information on upgrading a 3.5.x or 4.0.x Content Engine Web Service application to run in a 4.5 environment and beyond or to modify a 3.5 WSDL-based application to use the 4.0 WSDL, see "Upgrade Custom Applications" in the IBM FileNet P8 documentation.
