The WSDL validator, available in all WTP downloads, is located in plug-in org.wsdl.validation.The current version of the WSDL validator will only compile against Eclipse 3.2, WTP 1.5 and later.(These libraries are already included when using WTP.) Note: As of WTP 1.5, the classes discussed in this section have not been declared as API and are therefore subject to change.
Step 3 is handled by the WSDL validator and any extension namespace validators (more on extensions below).Step 4 is handled by any declared custom validators (more on this below as well).Each step must pass in order for the next step to run.The WSDL validator can be run outside of Eclipse (see Using the WSDL Validator Outside of Eclipse) and is also integrated with the WTP validation and URI resolution frameworks when used within Eclipse. Validate the WSDL document using semantic rules defined in the WSDL specification. Validate the WSDL document against custom validation rules, such as those defined by the Web Services Interoperability (WS-I) organization.WSDL validation can be thought of as a three step process: 1. (That is, ensure all tags are properly nested and closed.) 2. The WSDL validator handles validation according to the 4 step process defined above.
The WSDL validator provides, as you should expect, the ability to validate WSDL documents (as of WTP 1.5.2, WSDL 1.1 documents).
