I'm using JBoss 4.0.4 GA with EJB3-RC9-FD and JBossWS 1.0.3. NPE is thrown by org.jboss.ws.tools.schema.SchemaTypeCreator.java:578 during deployment.
After digging through the code I found Introspector, BeanInfo and PropertyDescriptor were causing the problem while analyzing one of my EJB methods. The method signature is:
public MyComplexType getMyComplexType();
public int getCodeCount(int type);
if (fieldType.equals(ParameterWrapping.WrapperType.class))
if (fieldType != null && fieldType.equals(ParameterWrapping.WrapperType.class)) continue;
import java.beans.BeanInfo; import java.beans.Introspector; import java.beans.PropertyDescriptor; import javax.ejb.SessionBean; public class TestIt { public int getCodeCount(int type) { return 1; } public static void main(String[] args) { try { Class javaType = TestIt.class; // taken from SchemaTypeCreator.java BeanInfo beanInfo = Introspector.getBeanInfo(javaType, Object.class); PropertyDescriptor[] props = beanInfo.getPropertyDescriptors(); int len = props != null ? props.length : 0; for (int i = 0; i < len && SessionBean.class.isAssignableFrom(javaType) == false; i++) { PropertyDescriptor prop = props; String fieldname = prop.getName(); Class fieldType = prop.getPropertyType(); // End of borrowed code...the next line throws NPE System.out.println(fieldType.getName()); } } catch(Exception ex) { ex.printStackTrace(); } } }
