>> It could come from tow reasons : - Which version of Xerces do you use ?? if it is the 1.3.1, then you can throw it away, and let's use Xerces1.2.3, because of a bug of Xerces1.3.1 !!!! - otherwise, take care to put every ".jar" and directory (where is stocked the java classes yuo want to use) before starting Tomcat (or other web server) !!! and I advise you to put all classes of you server in the same directory, put the "set classpath=%classpath%;." and start Tomcat from its directory !!! good luck I use the tomcat as webserver, and i have deployed the urn:Hello to the webservice, but i get this fault. Generated fault: Fault Code = SOAP-ENV:Server.BadTargetObjectURI Fault String = Unable to resolve target object: is anyone meet this error, and how to resolve it, thank you. HongBao Wang :)
