hi,

i managed to annotate my classes so that they can be easily marshalled and unmarshalled.
the only problem im still struggling with is that i can´t create the leading <janitor> and trailing </janitor> tag.

my generated xml looks like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <device uid="1" ip="127.0.0.1" name="heizung"> <actuator type="0" name="aktor" id="0"> <value>0.0</value> </actuator> </device>

i know that there is the @ElementWrap annotation but unfortunately i can´t use thise in my Device Class because of the @RootElement Annotation

package panel.xmlMappings; import java.net.InetAddress; import java.util.ArrayList; import java.util.List; import javax.xml.bind.annotation.XmlAttribute; import javax.xml.bind.annotation.XmlElementRef; import javax.xml.bind.annotation.XmlElementRefs; import javax.xml.bind.annotation.XmlRootElement; import javax.xml.bind.annotation.XmlTransient; @XmlRootElement class Device { @XmlElementRefs( { @XmlElementRef( type = Sensor.class ), @XmlElementRef( type = Actuator.class ), } ) private List<Component> components = new ArrayList<Component>(); private int uid; private String deviceName; private InetAddress ip; public Device() {}; public Device(int uid) { this(uid, null); } public Device(int uid, String deviceName) { this.uid = uid; this.deviceName = deviceName; } public void add(Component comp) { components.add(comp); } /** * @return the components */ @XmlTransient public List<Component> getComponents() { return components; } /** * @param components the components to set */ public void setComponents(List<Component> components) { this.components = components; } /** * @return the uid */ @XmlAttribute public int getUid() { return uid; } /** * @param uid the uid to set */ public void setUid(int uid) { this.uid = uid; } /** * @return the deviceName */ @XmlAttribute(name="name") public String getDeviceName() { return deviceName; } /** * @param deviceName the deviceName to set */ public void setDeviceName(String deviceName) { this.deviceName = deviceName; } /** * @return the ip */ @XmlAttribute() public String getIp() { return (this.ip == null ? "" : ip.getHostAddress()); } /** * @param ip the ip to set */ public void setIp(InetAddress ip) { this.ip = ip; } @Override public String toString() { StringBuffer sb = new StringBuffer(); sb.append("Device Daten:\n") .append("UID:\t").append(this.uid).append("\n") .append("Device Name:\t").append(this.deviceName).append("\n"); return sb.toString(); } @Override public boolean equals(Object obj) { if ( ( obj == null ) || !( obj.getClass().equals(this.getClass()) ) ) { return false; } Device other = (Device)obj; return this.uid == other.getUid(); } }

any ideas?

hi guys,

im new here, so firstly: hello :P

i have a problem related to xml processing.

i need to map these xml structure
<janitor> <device uid="123456" name="heizung"> <sensor id="123" type="float" name="sensor_amFenster"> <value>22.0</value> </sensor> <actuator id="124" type="boolean" name="aktor_amFenster"> <value>1.0</value> </actuator> </device> </janitor>

to java objects.

the <device> tag can ouccur only once where there can be an arbitrary number of <sensor> and <actuator> blocks.

in my frist approach i tried to solve it with sax, but i quickly saw that it will end up relatively complex so i discarded this way of solving the problem.

then i read about jaxb and it seems to be exactly what i need. but after working through some how to´s and introduction i still can´t solve my problem appropriate. for example i get error meesages like "if the annotation @XMLattribut is used, the class can´t have a @XMLelement tag" and so on.
(i used the variant with annotation because of the lack of a schema)

can you help me to figure out what classes i need and wich structure they need to have? the goal should be that i have a device object whith a list of components as attribute which holds the sensos and actuator objects.

thanks in advance

ps: i´ve uploaded the classes whith which i already tried and failed to solve the problem :P link:(edit: deleted)
pps: sorry for the bad englisch, as you can see from the xml i´m german...
