How do I reference a JAXB POJO in a mule flow

How do I reference a JAXB POJO in a mule flow - java

I have successfully unmarshalled an XML document into a JAXB object but now, I would like to reference the object in the flow and insert the value of it's properties into a database table.
The flow is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<mule xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns:mulexml="http://www.mulesoft.org/schema/mule/xml" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation" xmlns:spring="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-current.xsd

After unmarshalling, the object is instantiated as com.dhg.api.PAYMENTS#some_random_string, which makes it difficult to reference. So my question is simply, how can I refer to this object and be able to access the values for use elsewhere in the flow.
Thanks for your help.

Your setter/getter is not compliant with property names in :
public PAYMENTS.TRANSACTION getTRANSACTION() {
return transaction;
}
public void setTRANSACTION(PAYMENTS.TRANSACTION value) {
this.transaction = value;
}
So in <logger message="#[payload.transaction.email]" level="INFO" doc:name="Logger"/> the transaction part is null.
The correct getter name is getTransaction and is the same for setter. Change them please

I have tried to convert simple xml to pojo but that worked. But unable to find out what is problem with my pojo.

You don't need to use namespace = "http://adcb.com/poc/wiremock"
If there is no xmlns="http://adcb.com/poc/wiremock" inside

convert xml to java object using JAXB

I have the following XML and want to convert it into Java object.
<?xml version="1.0" encoding="UTF-8"?>
<datasources xmlns="http://www.jboss.org/ironjacamar/schema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.jboss.org/ironjacamar/schema http://docs.jboss.org/ironjacamar/schema/datasources_1_0.xsd">
<datasource jndi-name="java:jboss/datasources/FDMS_DemoDS" pool-name="FDMS_DemoDS">
<connection-url>jdbc:mysql://localhost:3306/demo?zeroDateTimeBehavior=convertToNull</connection-url>
<driver>com.mysql</driver>
<pool>
<max-pool-size>60</max-pool-size>
</pool>
<security>
<user-name>fduser</user-name>
<password>fdms!</password>
</security>
</datasource>
</datasources>
I am not sure what will be my corresponding java class when I use JAXB to convert it.
This is what I have tried so far based on my understanding:
#XmlRootElement
public class Datasources {
String connectionUrl;
String maxPoolSize;
String driver;
public String getConnectionUrl() {
return connectionUrl;
}
#XmlElement
public void setConnectionUrl(String connectionUrl) {
this.connectionUrl = connectionUrl;
}
public String getMaxPoolSize() {
return maxPoolSize;
}
#XmlElement
public void setMaxPoolSize(String maxPoolSize) {
this.maxPoolSize = maxPoolSize;
}
public String getDriver() {
return driver;
}
#XmlElement
public void setDriver(String driver) {
this.driver = driver;
}
}

Here's the Java classes with the JAXB annotation.
This is not 100% accurate but it may help you.

}

And to parse this xml I have created class to map the objects which creates the objects and print it in the console. But Don't know what I am doing wrong.
#XmlElementWrapper(name="Country")
public void setCountry(String Countryv) {
Country= Countryv;
}
#XmlElement (name = "name")
public void setname(String namev) {
name= namev;
}
#XmlElement (name = "capital")
public void setcapital(String capitalv) {
capital= capitalv;
}
#XmlElement (name = "population")
public void setpopulation(String populationv) {
population= populationv;
}
#XmlElementWrapper(name="states")
public void setType(String statesv) {
states = statesv;
}
#XmlElementWrapper(name="state")
public void setType(String statev) {
state = statev;
}
#XmlElement (name = "name")
public void setpopulation(String namev) {
name= namev;
}
#XmlElement (name = "pincode")
public void setpopulation(String pincodev) {
pincode= pincodev;
}
#XmlElement (name = "capital")
public void setpopulation(String capitalv) {
capital= capitalv;
}
when I run the program I m getting the
com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException:
counts of IllegalAnnotationExceptions
How to add wrapper anotations to wrapping the elements under separate headers and headers inside other headers.

Try this class
#XmlAccessorType(XmlAccessType.FIELD)
#XmlType(name = "", propOrder = {
"name",
"capital",
"population",
"states"
})
#XmlRootElement(name = "Country")
public class Country {
#XmlElement(required = true)
protected String name;
#XmlElement(required = true)
protected String capital;
#XmlElement(required = true)
protected String population;
#XmlElement(required = true)
protected Country.States states;
public String getName() {
return name;
}
public void setName(String value) {
this.name = value;
}
public String getCapital() {
return capital;
}
public void setCapital(String value) {
this.capital = value;
}
public String getPopulation() {
return population;
}
public void setPopulation(String value) {
this.population = value;
}
public Country.States getStates() {
return states;
}
public void setStates(Country.States value) {
this.states = value;
}

This worked for me
class Country {
#XmlElement
String name;
//...
#XmlElementWrapper(name="states")
List<State> state;
}
class State {
#XmlElement
String name;
//..
}

Want to create a hashmap with a key(String) and value(Node)

I want to create a hashmap which is to have as 'Key' and the node as 'Value'. Can i know how do i do that using hashmap ? I will be creating two hashmaps on similar pattern, later want to compare it based on the 'Key(srv_field). Let me know how do i initialise and store the required data into hashmap.
Input xml is as below.

Map<String,Node> map = new HashMap<String,Node>();
// or new HashMap<>();
map.put("asdf", new Node());
To get a value:
Node n = map.get("asdf");
You can compare values by getting Nodes from two Maps and comparing them, possibly with .equals().
There are other Map methods, which are detailed in the documentation.

Reading XML files from java

I am trying to read an XML file from java program. I am able to read its contents.I am posting the XML file from which i am reading contents.
<?xml version="1.0" encoding="UTF-8" ?>
<customer id="100">
<age>29</age>
<name>lucifer</name>
</customer>
i am able to write its contents through java program i am posting my code..
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
#XmlRootElement
public class Customer {
String name;
int age;
int id;
public String getName() {
return name;
}
#XmlElement
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
#XmlElement
public void setAge(int age) {
this.age = age;
}
public int getId() {
return id;
}
#XmlAttribute
public void setId(int id) {
this.id = id;
}
}
public class CheckClass {
public static void main(String[] args) {
try {
File file = new File("./file/NewFile.xml");
JAXBContext jaxbContext = JAXBContext.newInstance(Customer.class);
Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
Customer customer = (Customer) jaxbUnmarshaller.unmarshal(file);
System.out.println(customer.age);
} catch (JAXBException e) {
e.printStackTrace();
}
}
}
But i have to read values from this XML file which i can not.This is my XML file
<?xml version="1.0" encoding="UTF-8"?>
<DBConfig ID="1" Name ="" DriverName="" HostName="localhost" PortName="" DBName="" ServiceName="" User="" PassWord="" sid="">
<TableConfig ID= "1" TableName="">

</DBConfig>
When i am trying to access this xml values through java class i am getting this error..

System.out.println(db.HostName);
} catch (JAXBException e) {
e.printStackTrace();

}
}
can anyone help

Note that you are annotating Attribute as Element. Fix that.
Even after that if problem occurs -
Try using - #XmlAccessorType(XmlAccessType.FIELD)
Move #XmlAttribute(name = "HostName") annotations to fields instead of accessor methods.
I am not sure if this is your problem. I faced a similar problem and this helped me. I wont guarantee that it will solve your problem but prima facie, it appears that above can fix it.

dbName, sid are Attributes, but you have annotated them #XmlElement. change all the attributes to #XmlAttribute.

Why don't you use
Xstream library
Example:
import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.annotations.XStreamAlias;
import com.thoughtworks.xstream.annotations.XStreamAsAttribute;
#XStreamAlias("Cat")
class Cat {
#XStreamAsAttribute
int age;
String name;
}
public class XStreamDemo {
public static void main(String[] args) {
XStream xstream = new XStream();
xstream.processAnnotations(Cat.class);
String xml = "<Cat age='4' ><name>Garfield</name></Cat>";
Cat cat = (Cat) xstream.fromXML(xml);
System.out.println("name -> " + cat.name);
System.out.println("age -> " + cat.age);
}
}
You need to add Xstream jar files in to classpath.

Use these classes.
#XmlAccessorType(XmlAccessType.FIELD)
#XmlType(name = "", propOrder = {

#XmlRootElement(name = "TableConfig")
