I have a complex XML Structure as below which needs to be unmarshalled:
<abc>
<pqr>
<attribute>name</attribute>
<entry>
<priorityKey>
<class>123</class>
<reason>abc</reason>
</prioritykey>
<priority> 1 </priority>
</entry>
<entry>
<prioritykey>
<class>456</class>
<reason>abc1</reason>
</prioritykey>
<priority>2</priority>
</entry>
</pqr>
<pqr>
'''
'''
</pqr>
</abc>
abc is the root node. It can have multiple pqr elements. Each pqr element has one attribute node and multiple entry nodes. So I believe it will be of type HashMap(entry,attribute).
Each entry in turn has prioritykey and priority which I believe will be of type HashMap (prioritykey,priority).
Need to unmarshall this xml but not getting how to configure the XMLAdapter
Here, create the contract first. I created one as part of my learning process...
<xs:element name="abc" type="abcType" />
<xs:complexType name="abcType">
<xs:sequence>
<xs:element name="pqr" type="pqrType" minOccurs="1"
maxOccurs="unbounded" />
</xs:sequence>
</xs:complexType>
<xs:complexType name="pqrType">
<xs:sequence>
<xs:element name="attribute" type="xs:string" minOccurs="1"
maxOccurs="1" />
<xs:element name="entry" type="entryType" minOccurs="1"
maxOccurs="unbounded" />
</xs:sequence>
</xs:complexType>
<xs:complexType name="entryType" >
<xs:sequence>
<xs:element name="priorityKey" type="priorityKeyType"
minOccurs="1" maxOccurs="1" />
<xs:element name="priority" type="xs:int" minOccurs="1"
maxOccurs="1" />
</xs:sequence>
</xs:complexType>
<xs:complexType name="priorityKeyType">
<xs:sequence>
<xs:element name="class" type="xs:int" minOccurs="1"
maxOccurs="1" />
<xs:element name="reason" type="xs:string" minOccurs="1"
maxOccurs="1" />
</xs:sequence>
</xs:complexType>
Copy and save this in an fileName.xsd file.
Now, generate JAXB classes or artifacts. If you are using an IDE, then this is simple. Click on the fileName.xsd file and you should get some option to generate JAXB artifacts. Otherwise, you can always use jaxb-xjc.jar present in the lib present in the JAXB download.
Command for the same - java -jar jaxb-xjc.jar fileName.xsd.
As the artifacts are in place, you can use them to unmarshall the xml content in question.

I have a xsd where there are 2 complextype elements under <Customer> complextype. One is <NormalCustomer> and <PrivilegedCustomer>. In my xml, I want either Normal or Privileged customer to be present under <Customer> tag based on the id attribute of Normal/Privileged customers.
below is my xsd
<xs:choice>
<xs:element name="normalCustomer" type="tns:normalCustomer" minOccurs="0" nillable="true"/>
<xs:element name="privilegedcustomer" type="tns:privilegedcustomer" minOccurs="0" nillable="true"/>
</xs:choice>
Complextype NormalCustomer
<xs:complexType name="normalCustomer">
<xs:sequence>
<xs:element name="id" type="xs:long"/>
<xs:element name="customerName" type="xs:string" minOccurs="1"/>
<xs:element name="customerType" type="xs:string" minOccurs="1"/>
</xs:sequence>
</xs:complexType>
Complextype PrivilegedCustomer
<xs:complexType name="privilegedCustomer">
<xs:sequence>
<xs:element name="id" type="xs:long"/>
<xs:element name="customerName" type="xs:string" minOccurs="1"/>
<xs:element name="customerType" type="xs:string" minOccurs="1"/>
</xs:sequence>
</xs:complexType>
Note: Am using JAXB for processing
Please suggest me how can I modify the tag to achieve my requirement.
Remove minOccurs="0" nillable="true" from both elements. The <xs:choice> enforces that exactly one of the elements are present. If none present are allowed, add minOccurs="0" to <xs:choice>.
plz help me to convert the below xsd into java code. I am using maven also.

You can use xjc, which comes with your Java development kit to create Java classes from an XML schema file. You can run this from the command line:
xjc schemafile.xsd
You'll have to wrap the elements like this:
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<!-- your elements -->
</xs:schema>
My transaction xml is shown below
<?xml version= "1.0"?>
<transactionlist>
<transaction action="c">
<transactionid>t004</transactionid>
<transactiondate>11/06/2013</transactiondate>
<merchantdetails>Sony wholesale Dealer</merchantdetails>
<itempurchased>3</itempurchased>
<amount>40399</amount>
<description>sony laptops</description>
</transaction>
<transaction action="d">
<transactionid>t003</transactionid>
</transaction>
<transaction action="u">
<transactionid>T001</transactionid>
<transactiondate>20/08/2013</transactiondate>
<merchantdetails>samsung Axses</merchantdetails>
<itempurchased>1</itempurchased>
<amount>40000</amount>
<description>samsung smart phone</description>
</transaction>
</transactionlist>
I have parsed the element itempurchased in above xml and stored it in integer variable. How to validate itempurchased only for numbers. that is i want to check whether itempurchased is number. pls provide suggestions
the best way should be validate xml against an xsd, where itempurchased would be of type xsd:int
below the xsd
<?xml version="1.0" encoding="utf-8"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="transactionlist">
<xs:complexType>
<xs:sequence>
<xs:element maxOccurs="unbounded" name="transaction">
<xs:complexType>
<xs:sequence>
<xs:element name="transactionid" type="xs:string" />
<xs:element minOccurs="0" name="transactiondate" type="xs:string" />
<xs:element minOccurs="0" name="merchantdetails" type="xs:string" />
<xs:element minOccurs="0" name="itempurchased" type="xs:int" />
<xs:element minOccurs="0" name="amount" type="xs:int" />
<xs:element minOccurs="0" name="description" type="xs:string" />
</xs:sequence>
<xs:attribute name="action" type="xs:string" use="required" />
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
Here Validating XML against XSD the code for validate xml against xsd
If you are marshaling your xml to a java bean then you may try using the Java6 Bean Validation Framework. Read more about it here:
http://docs.oracle.com/javaee/6/tutorial/doc/gircz.html
It is as simple as putting an annotation on your bean:
public class MyXMLBean {
#Max(10)
#Min(5)
private int itempurchased;
}
The above bean will allow setting the value of itempurchased between min and max values mentioned in the annotations.
Part of my xsd file looks like this:
<xs:complexType name="group">
<xs:sequence maxOccurs="unbounded" minOccurs="1">
<xs:element name="title" type="xs:string"/>
<xs:element name="description" type="xs:string"/>
<xs:element name="module" type="module" nillable="true" maxOccurs="unbounded"/>
</xs:sequence>
<xs:attribute name="name" type="xs:string" />
</xs:complexType>
When I generate my classes using Jaxb in Eclipse. The "Group" class generates a method called:
public List<JAXBElement<?>> getTitleAndDescriptionAndModule();
How do I change the xsd so that I get getter for each of the elements?
I make xml file using Jaxb from a xml schema my existing xml file looks like
<transaction>
<id>
<in>computer</in>
<sn>1234567</sn>
<book>JAVA</book>
<author>klen</author>
</id>
<data>
<dateTime>2011-06-24T17:08:36.3727674+05:30</dateTime>
<key>Err</key>
</data>
</transaction>
but I want to add inline schema before <id> node
My schema is looking like
<xs:schema id="transaction" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
<xs:element name="transaction" msdata:IsDataSet="true" msdata:UseCurrentLocale="true">
<xs:complexType>
<xs:choice minOccurs="0" maxOccurs="unbounded">
<xs:element name="id">
<xs:complexType>
<xs:sequence>
<xs:element name="in" type="xs:string" minOccurs="0" />
<xs:element name="sn" type="xs:string" minOccurs="0" />
<xs:element name="book" type="xs:string" minOccurs="0" />
<xs:element name="author" type="xs:string" minOccurs="0" />
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="data">
<xs:complexType>
<xs:sequence>
<xs:element name="dateTime" type="xs:dateTime" minOccurs="0" />
<xs:element name="key" type="xs:string" minOccurs="0" />
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="productData">
<xs:complexType>
<xs:sequence>
<xs:element name="dateTime" type="xs:dateTime" minOccurs="0" />
<xs:element name="key" type="xs:string" minOccurs="0" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:choice>
</xs:complexType>
</xs:element>
</xs:schema>
now I want to add this before node under node.
Is it possible using Jaxb in first time?I cannot generate xml file with inline schema using jaxb.Due to the large size of my xml I cannot do this using Dom parser.Presently I try that at first generate xml file with data using jaxb and then rewrite the xml file and add schema under <transaction> node before <id> node.
I will prefer sun provided api.I am new in java so if some codesnips will be added it will be help full for me.
