I'm using dwr and spring and I get this error:
java.lang.IllegalArgumentException: Javascript name * is used by 2 classes
I found nothing helpful on Google, do you know why I'm getting this error?
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:dwr="http://www.directwebremoting.org/schema/spring-dwr"

<bean id="ping" class="com.mycompany.Ping">
<dwr:remote javascript="rpcPing">

</dwr:remote>
</bean>
</beans>
Found.
Because the version of the DWR's jar did not match the version of DWR's schema
In my case the reason was that the relevant snippets in dwr.xml were there twice.
<create creator="new" javascript="Tab">

I need to parse this XML file and assign values to its corresponding class objects.Which is the best option to parse such an xml file.
JAXB sounds good to me but the POJOs were already written by someone and now i will have to rewrite and deploy them.ALso teh xml file has some errors while running xjc command.
DOM approach seems to be very cumbersome n error prone.
Please suggest.
PS:Kindly excuse my beginner level knowledge.
the JDK project comes with SAX(Simple API for XML) accessible by importing org.xml.sax.*.
You may take a look at this https://www.tutorialspoint.com/java_xml/java_sax_parse_document.htm for an introduction to the subject.
I have developed Odata service for a system entity which generates a metadata but however I cant figure out how to add Annotations element to it. Sample Metadata generated is as follows :-
<?xml version="1.0" encoding="utf-8"?>
<edmx:Edmx xmlns:edmx="http://schemas.microsoft.com/ado/2007/06/edmx" xmlns:sap="http://www.sap.com/Protocols/SAPData" Version="1.0">
<edmx:DataServices xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"
m:DataServiceVersion="1.0">
<Schema xmlns="http://schemas.microsoft.com/ado/2008/09/edm" Namespace="myNamespace" sap:schema-version="1">
<EntityType Name="System">
<Key>
<PropertyRef Name="Id" />
</Key>
<Property Name="Id" Type="Edm.Int32" Nullable="false" />
<Property Name="name" Type="Edm.String" sap:label="System Name" sap:creatable="false"
sap:updatable="false" sap:sortable="false" sap:required-in-filter="true"/>
<Property Name="description" Type="Edm.String" />
<Property Name="status" Type="Edm.String" />
<Property Name="type" Type="Edm.String" />
</EntityType>
<EntityContainer Name="ODataEntityContainer" m:IsDefaultEntityContainer="true">
<EntitySet Name="Systems" EntityType="myNamespace.System" />
<FunctionImport Name="NumberOfSystems" ReturnType="Collection(myNamespace.System)"
m:HttpMethod="GET" />
</EntityContainer>
</Schema>
</edmx:DataServices>
</edmx:Edmx>
I need to add following elements to above metatada
<Annotations Target="myNamespace.System"
xmlns="http://docs.oasis-open.org/odata/ns/edm">
<Annotation Term="com.sap.vocabularies.UI.v1.LineItem">
<Collection>
<Record Type="com.sap.vocabularies.UI.v1.DataField">
<PropertyValue Property="Value" Path="name" />
</Record>
<Record Type="com.sap.vocabularies.UI.v1.DataField">
<PropertyValue Property="Value" Path="description"/>
</Record>
<Record Type="com.sap.vocabularies.UI.v1.DataField">
<PropertyValue Property="Value" Path="status" />
</Record>
</Collection>
</Annotation>
</Annotations>
I came across the org.apache.olingo.commons.api.edm.provider.annotation package but cant find any suitable API. Please let me know how should I proceed.
Thanks in advance.
The annotations you would like to use have been introduced with OData V3 which is why they are not directly supported with the Olingo V2 library.
You can use the EdmProvider AnnotationElement and AnnotationAttribute classes to mimic this behaviour though. For example You can create a AnnotationElement with the name "Annotations" this element will then have the "AnnotationAttribute" Target=SomeString. Since an "AnnotationElement" can have child elements you can put your Collection element there. Namespaces are also handled with "AnnotationAttributes".
You can only attach the annotation to Edm elements which are derived from the EdmAnnotatable interface. So this is a difference to V3.
This is currently the only way to get this behaviour with Olingo V2.
Using mybatis generator for classes of db tables, I found that sometimes it introduces newlines into function signatures in the .java files generated, *Example.java and *Mapper.java.
Can this be avoided someway, as it makes very difficult sometimes to check svn modifications?
I used the following configuration:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd" >
<generatorConfiguration >
<classPathEntry location="myFolder/myDriver.jar"/>
<context id="MyDB" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressDate" value="true" />
</commentGenerator>
<jdbcConnection driverClass="myDriver" connectionURL="myUrl" userId="myUserID" password="myPwd" />
<javaModelGenerator targetPackage="myPackage" targetProject="myProject" >
<property name="enableSubPackages" value="false" />
</javaModelGenerator>
<sqlMapGenerator targetPackage="myMapper" targetProject="myProject">
<property name="enableSubPackages" value="false" />
</sqlMapGenerator>
<javaClientGenerator targetPackage="myMapper" targetProject="myProject" type="XMLMAPPER">
<property name="enableSubPackages" value="false" />
</javaClientGenerator>
<table schema="MY_SCHEMA" tableName="TABLE_TO_GENERATE">
</table>
</context>
</generatorConfiguration>
In Spring, I'm declaring my org.springframework.oxm.jaxb.Jaxb2Marshaller, but I also want to declare an external binding file:
<bean id="myMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
<property name="contextPath" value="com.path.to.pojos" />
<property name="jaxbContextProperties">
<util:map>
<entry key="eclipselink.oxm.metadata-source">
<list>
<value>com/path/to/schema/binding.xjb</value>
</list>
</entry>
</util:map>
</property>
<property name="schema" value="classpath:com/path/to/schema/myService.xsd"/>
</bean>
My binding file looks like this:
<jaxb:bindings version="1.0"
jaxb:version="2.0"
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:annox="http://annox.dev.java.net"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
jaxb:extensionBindingPrefixes="xjc annox">
<jaxb:bindings schemaLocation="myService.xsd" node="/xs:schema">
<jaxb:globalBindings>
<xjc:javaType name="java.util.Date" xmlType="xs:date"
adapter="com.some.path.to.custom.adapter.DateAdapter" />
</jaxb:globalBindings>
<!-- More Declarations -->
</jaxb:bindings>
</jaxb:bindings>
This setup works fine with XJC to generate the objects from the schema along with the external binding file. But I can't get the appropriate setup for my Spring configuration.
I get the following error:
org.xml.sax.SAXParseException; lineNumber: 9; columnNumber: 77; unexpected element (uri:"http://java.sun.com/xml/ns/jaxb", local:"bindings"). Expected elements are <{http://www.eclipse.org/eclipselink/xsds/persistence/oxm}xml-schema>,<{http://www.eclipse.org/eclipselink/xsds/persistence/oxm}xml-schema-type>,<{http://www.eclipse.org/eclipselink/xsds/persistence/oxm}xml-schema-types>,<{http://www.eclipse.org/eclipselink/xsds/persistence/oxm}xml-java-type-adapters>,<{http://www.eclipse.org/eclipselink/xsds/persistence/oxm}xml-registries>,<{http://www.eclipse.org/eclipselink/xsds/persistence/oxm}xml-enums>,<{http://www.eclipse.org/eclipselink/xsds/persistence/oxm}java-types>
I'm stuck on this, and I really need the binding file to be separate than my schema. I can't find any example of this setup online, I would love an example on how to properly configure an external binding file with the JaxB2Marshaller.
Please let me know if my question is incomplete or if more information is required.
Thanks,
JP
As far as I know, bindings file is only used during the compilation time, to derive Java classes from the XML Schema. So it does not make sense to configure it in runtime, on a marshaller. Neither Spring nor JAXB will consider it. All you could have configured with the bindings file is already in your com.path.to.pojos.* classes.
I am trying to get the basic http rest helloworld example working in Mule but I get this error
Could not find a transformer to transform "SimpleDataType{type=java.lang.String, mimeType='*/*'}" to "SimpleDataType{type=java.io.InputStream, mimeType='*/*'}". (org.mule.api.transformer.TransformerException). Message payload is of type: String
This is my config file:

And my jersey service class
#Path("version")
public class AdminApi {
#GET
#Produces("text/plain")
public String sayHelloWithUri() {
return "Version 999 " ;
}
}
I am trying to access the service using:
http://localhost:8081/api/version
which I believe should be the right url but no luck I always get the above exception message.
Anyone has an idea what this could be?

Your configuration runs just fine with Mule 3.3.0 (tested outside of Tomcat, in Eclipse) so I suspect the problem comes from either missing or duplicated JARs on your web application classpath.
Check the JARs that get packaged in WEB-INF/lib and potential manually added JARs in Tomcat's /lib directory.
<flow name="HelloWorld">
<inbound-endpoint address="http://localhost:8081/api"/>
<jersey:resources>
<component class="com.helloworld.AdminApi"/>
</jersey:resources>
</flow>
and use this url. http://localhost:8081/api/version
result is -Version 999
If you are running with Mule Studio 3.3.0, you must put the mimeType.
Example:
<flow name="RestServiceFlow" doc:name="RestServiceFlow">
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8083" doc:name="HTTP" mimeType="application/json"/>
<jersey:resources doc:name="RESTUTCNotification">
<component class="example.esb.restApi"/>
</jersey:resources>
</flow>
