java.lang.NoClassDefFoundError: org/apache/xerces/jaxp/datatype/XMLGregorianCalendarImpl$Parser

When you encounter the following error that related to web service. java.lang.NoClassDefFoundError: org/apache/xerces/jaxp/datatype/XMLGregorianCalendarImpl$Parser Solution 1: Ensure no xercesImpl.jar in your classpath since the implementation of xerce is built-in wiht JAVA SE 1.6.

Start or restart all of the servers in the domain. ============================================= Using WebLogic Scripting Tool (WLST) Using WLST to Check the Value of enforce-valid-basic-auth-credentials The Administration Console does not display or log the enforce-valid-basic-auth-credentials setting. However, you can use WLST to check the value in a running server. Remember that enforce-valid-basic-auth-credentials is a domain-wide setting. The WLST session shown below demonstrates how to check the value of the enforce-valid-basic-auth-credentials flag in a sample running server. Example: wls:/offline> connect('weblogic','weblogic123','t3://localhost:7002') Connecting to t3://localhost:7002 with userid weblogic ... Successfully connected to Admin Server 'AdminS...
