I'm trying to marshall a list containing objects into an XML string. I was able to marshall a single object into an XML string but am struggling on what is needed to do a list? I am including an example using JBoss Tools Web Services. It will query the database and receive a back a list of WebCalendar objects. If I create a single object and marshall it will work. However, I need to marshall the list so that it creates multiple entries for each object in the marshalled XML. If you can advise I would appreciate it. Here is an example code: This is the class that will query the database which returns a list of WebPayCalendar objects I then try to marshall the list into an XML string: @WebMethod public String retrievePsWebPayCalendar() { try { /************************************************************************** * The following example marshals an object class into an XML string which * is returned to the caller. The object is an entity representing a * row on the database. **************************************************************************/ WebPayCalendarList selectCalendar = (WebPayCalendarList) Component.getInstance("webPayCalendarList"); // Retrieve the entire list of web pay calendar dates List pc = selectCalendar.getResultList(); // For a test retrieve only the first web calendar date object WebPayCalendar wpc = pc.get(0); // Marshal the calendar information into an XML string and return it JAXBContext context = JAXBContext.newInstance(WebPayCalendar.class); Marshaller marshaller = context.createMarshaller(); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); marshaller.marshal(pc, System.out); return result.getWriter().toString(); } catch (Exception e) { return "Error: " + e.getMessage(); } } This is the object Class: package org.domain.PSWebService.entity; import java.io.Serializable; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.Id; import javax.persistence.Table; import javax.persistence.UniqueConstraint; import javax.xml.bind.annotation.XmlRootElement; import javax.xml.bind.annotation.XmlType; import org.hibernate.validator.Length; @Entity @Table(name="WEB_PAY_CALENDAR", uniqueConstraints = {@UniqueConstraint(columnNames={"RUN_ID"})}) @XmlRootElement public class WebPayCalendar implements Serializable { //WEB_PAY_CALENDAR Data Columns @Length(max=3) private String payGroup; @Id @Length(max=10) @Column(name="RUN_ID") private String runId; @Column(name="CHECK_DT") private java.util.Date checkDt; @Column(name="PAY_BEGIN_DT") private java.util.Date payBeginDt; @Column(name="PAY_END_DT") private java.util.Date payEndDt; @Length(max=1) @Column(name="PAY_CONFIRM_RUN") private String payConfirmRun; public String getPayGroup() { return payGroup; } public void setPayGroup(String payGroup) { this.payGroup = payGroup; } public String getRunId() { return runId; } public void setRunId(String runId) { this.runId = runId; } public java.util.Date getCheckDt() { return checkDt; } public void setCheckDt(java.util.Date checkDt) { this.checkDt = checkDt; } public java.util.Date getPayBeginDt() { return payBeginDt; } public void setPayBeginDt(java.util.Date payBeginDt) { this.payBeginDt = payBeginDt; } public java.util.Date getPayEndDt() { return payEndDt; } public void setPayEndDt(java.util.Date payEndDt) { this.payEndDt = payEndDt; } public String getPayConfirmRun() { return payConfirmRun; } public void setPayConfirmRun(String payConfirmRun) { this.payConfirmRun = payConfirmRun; } } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4152353#...
