how to create custom content model using JCR?

[naveenkumar]

Hi, I am trying to create custom content using JCR. I created a new custom tag for content and modifies some xmls. but unable to create content using JCR. Please if anyone can help me…

this is my code………..in the code - "dml is my custom tag"

Node rootNode = session.getRootNode();
           Node companyHome = rootNode.getNode("app:company_home");
   
           // create the content node
           String name = "JCR sample (" + System.currentTimeMillis() + ")";
           Node content = companyHome.addNode("dml:" + name, "dml:newscontent");
          // Node content = companyHome.addNode("cm:" + name, "cm:content");
           content.setProperty("cm:name", name);

           // add titled aspect (for Web Client display)
           //content.addMixin("cm:titled");
          // content.setProperty("cm:title", name);
           //content.setProperty("cm:description", name);
           content.setProperty("dml:Headline", name);

           //
           // write some content to new node
           //
          //content.setProperty("cm:content", "The quick brown fox jumps over the lazy dog");
          
           //
           // To set the content mime type, we need to use an Alfresco native service
           // as there isn't an equivalent call in JCR
           //
           setMimeType(context, content, MimetypeMap.MIMETYPE_TEXT_PLAIN);

Can you provide more info?

What error are you getting?
What's your model?
What bits of xml did you modify?

Check my custom model::

<?xml version="1.0" encoding="UTF-8"?> <!– Definition of new Model –> <!– The important part here is the name - Note: the use of the my: namespace which is defined further on in the document –> <model name="dml:content" xmlns="http://www.alfresco.org/model/dictionary/1.0"> <!– Optional meta-data about the model –>    <description>Modele NewsML</description>    <author>Christophe</author>    <version>0.1</version> <!– Imports are required to allow references to definitions in other models –>    <imports> <!– Import Alfresco Dictionary Definitions –>    <import uri="http://www.alfresco.org/model/dictionary/1.0" prefix="d"/> <!– Import Alfresco Content Domain Model Definitions –>    <import uri="http://www.alfresco.org/model/content/1.0" prefix="cm"/> </imports> <!– Introduction of new namespaces defined by this model –> <!– NOTE: The following namespace my.new.model should be changed to reflect your own namespace –>    <namespaces>    <namespace uri="com.company.dml.model" prefix="dml"/>   </namespaces> <types><type name="dml:newscontent">          <title>Newscontent</title>          <parent>cm:content</parent>          <properties>             <property name="dml:ProviderId">                <type>d:text</type>             </property>             <property name="dml:DateId">                <type>d:long</type>             </property>             <property name="dml:NewsItemId">                <type>d:long</type>             </property>             <property name="dml:RevisionId">                <type>d:long</type>             </property>             <property name="dml:PublicIdentifier">                <type>d:text</type>             </property>            </properties>       </type> </types></model>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I have doubt about namespace uri.. is that correct???

Here is my example-model-context.xml…

<?xml version='1.0' encoding='UTF-8'?> <!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'> <beans> <!– Registration of new models –> <bean id="extension.dictionaryBootstrap" parent="dictionaryModelBootstrap" depends-on="dictionaryBootstrap"> <property name="models"> <list> <value>alfresco/extension/newsModel.xml</value></list> </property> </bean> </beans>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

For your information i am able to create content using custom model through web client… i am able to see the meta properties…. when i try to use FirstJcrClient not able to see…
