Data Import in Solr 4.2 not working? - java

My data-config.xml is as follows and I have kept in the the Conf folder along with the solrconfig.xml :-
<dataConfig>
<dataSource name="Sample" driver="org.postgresql.Driver" url="jdbc:postgresql://localhost:5432/Sample" user="postgres" password="P#ssword">
<document name="oneDocs">
<entity dataSource="Sample" name="entity1" query="select FirstName from Employee">
<field column="EmpId" name="EmpId" />
<field column="FirstName" name="FirstName" />
<field column="LastName" name="LastName" />
</entity>
</document>
</dataSource>
</dataConfig>
And my solrconfig.xml is as follows :-
<requestHandler name="/dataimport"
class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">data-config.xml</str>
</lst>
</requestHandler>
I have also tried to add the libraries in the following ways :-
<lib dir="../../../contrib/extraction/lib" regex=".*\.jar" />
<lib dir="../../../dist/" regex="solr-cell-\d.*\.jar" />
<lib dir="../../../contrib/clustering/lib/" regex=".*\.jar" />
<lib dir="../../../dist/" regex="solr-clustering-\d.*\.jar" />
<lib dir="../../../contrib/dataimporthandler/lib/" regex=".*\.jar" />
<lib dir="../../dist/" regex="solr-dataimporthandler-\d.*\.jar" />
<lib dir="../../dist/" regex="postgresql-9.2-1002.jdbc3-\d.*\.jar" />
<lib dir="../../../contrib/langid/lib/" regex=".*\.jar" />
<lib dir="../../../dist/" regex="solr-langid-\d.*\.jar" />
<lib dir="../../../contrib/velocity/lib" regex=".*\.jar" />
<lib dir="../../../dist/" regex="solr-velocity-\d.*\.jar" />
<!-- If a 'dir' option (with or without a regex) is used and nothing
is found that matches, it will be ignored
-->
<lib dir="/total/crap/dir/ignored" />
I am getting the same error constantly :-

Please help to resolve this.This is eating away most of the time. Thanks
NOTE: I am using Postgres and Apache Tomcat 7 and Java 7 .

Your data-config.xml is flawed. You have wrapped the document elment into the datasource element. Both need to be on the same level as direct child of the dataConfig element.
This is why the exception you posted states:
Data Config problem: DataImportHandler configuration file must have
one node.
The XML parser does not find the document element as child node of dataConfig.
Try it like this:
<dataConfig>
<dataSource name="Sample" driver="org.postgresql.Driver" url="jdbc:postgresql://localhost:5432/Sample" user="postgres" password="P#ssword" />
<document name="oneDocs">
<entity dataSource="Sample" name="entity1" query="select FirstName from Employee">
<field column="EmpId" name="EmpId" />
<field column="FirstName" name="FirstName" />
<field column="LastName" name="LastName" />
</entity>
</document>
</dataConfig>

In your data-config.xml the document element should be a sibling to the dataSource element, not a child.
ie it should look like this;
<dataConfig>
<dataSource>
..
</dataSource>
<document>
..
</document>
</dataConfig>

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.

How to add Annotations elements in metadata generated by Apache Olingo V2.0?

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.

How can I create a blob index field correctly with Solr 5?

I think the title of my question explains much of what I need. I am using the Data Importer Handler of Apache SOLR 5. I configured my solrconfig.xml, schema.xml and data-config.xml. It's working for now.
However, I need to add one more field. An Oracle Blob field. First, let me show my configurations:
data-config.xml
<dataConfig>
<!-- Datasource -->
<dataSource name="myDS"
setReadOnly="true"
driver="oracle.jdbc.OracleDriver"
url="jdbc:oracle:thin:#//server.example.com:1521/service_name"
user="user"
password="pass"/>
<document name="products">
<entity name="product"
dataSource="myDS"
query="select * from products"
pk="id"
processor="SqlEntityProcessor">
<field column="id" name="id" />
<field column="name" name="name" />
<field column="price" name="price" />
<field column="store" name="store" />
<!-- I've added this blob field -->
<field column="picture" name="picture" />
</entity>
</document>
</dataConfig>
solrconfig.xml
<requestHandler name="/products" class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">data-config.xml</str>
</lst>
</requestHandler>
<!-- JDBCs -->
<lib dir="../../../lib" />
My fields in schema.xml
<field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false" />
<field name="_version_" type="long" indexed="true" stored="true"/>
<field name="_text" type="string" indexed="true" stored="false" multiValued="true"/>
<field name="name" type="string" indexed="true" stored="true"/>
<field name="price" type="float" indexed="true" stored="true"/>
<!-- BLOB field -->
<field name="picture" type="binary" indexed="true" stored="true"/>
<copyField source="*" dest="_text"/>
<!-- ommited solr default fields -->
Now, when I start a full-importer, SOLR only indexes some records. This is the output after SOLR finish the importing:
Indexing completed. Added/Updated: 64 documents. Deleted 0 documents. (Duration: 04s)
Requests: 1 (0/s), Fetched: 1369 (342/s), Skipped: 0, Processed: 64 (16/s)
Started: less than a minute ago
As you can see, I have 1369 records, but SOLR only index 64 documents. If I remove the field picture from schema or, set index and stored attributes to false, SOLR import all documents.
I opened the SOLR log, and found this error when importing the blob field:
3436212 [Thread-19] WARN org.apache.solr.handler.dataimport.SolrWriter – Error creating document : SolrInputDocument(fields: [name=PRODUCTNAME, price=PRICE, store=STORE, picture=oracle.sql.BLOB#4130607a, _version_=1497915495941144576])

I checked querying directly against database, and it's working fine. I am using SOLR 5, ojdbc7 and Java 8. How can I use the binary field correctly in SOLR?
Update
I've changed the properties of picture in schema.xml setting indexed=false. This way:
<!-- BLOB field -->
<field name="picture" type="binary" indexed="false" stored="true"/>
Then, I restarted SOLR, reloaded my core, and did a Full-Import again. No success and same exception. The same 64 documents that I described above was imported and the field picture does not appear in JSON response. The query I execute is:
/select?q=*%3A*&wt=json&indent=true

Ofbiz service creation

Starting to learn ofbiz, I am following the tutorial here:
https://cwiki.apache.org/confluence/display/OFBIZ/OFBiz+Tutorial+-+A+Beginners+Development+Guide#OFBizTutorial-ABeginnersDevelopmentGuide-SecureYourApplicationbyAuthentication
Now I am in the step to make the list form of persons editable. In this step I need to create a service which will be used for auto-fields-service. Below I give the code which I have done.
In the controller.xml of my componenent I have created a requestMaps as follows:
<request-map uri="updatePracticePerson">
<security https="true" auth="true"/>
<event type="service" invoke="updatePracticePerson"/>
<response name="success" type="view" value="personForm"/>
<response name="error" type="view" value="personForm"/>
</request-map>
Moving now to the PracticeScreens.xml i have the following for personForm:
<screen name="personForm">
<section>
<actions>
<set field="headerItem" value="personForm"/>
<set field="titleProperty" value="PageTitlePracticePersonForm"/>
<entity-condition entity-name="Person" list="persons"/>
</actions>
<widgets>
<decorator-screen name="CommonPracticeDecorator" location="${parameters.mainDecoratorLocation}">
<decorator-section name="body">
<label text="Person List" style="h2"/>
<include-form name="ListPersons" location="component://practice/widget/PracticeForms.xml"></include-form>
</decorator-section>
</decorator-screen>
</widgets>
</section>
The above includes the ListPersons from PracticeForms.xml, which I have as :
<form name="ListPersons" type="list" list-name="persons" list-entry-name="person" target="updatePracticePerson" paginate-target="personForm">
<auto-fields-service service-name="updatePracticePerson" default-field-type="edit" map-name="person"/>
<field name="partyId"><hidden/></field>
<field name="submitButton" title="Update" widget-style="smallSubmit"><submit button-type="button"/></field>
<field name="deletePracticePerson" title="Delete Person" widget-style="buttontext">
<hyperlink target="deletePracticePerson?partyId=${person.partyId}" description="${uiLabelMap.CommonDelete}" also-hidden="false"/>
</field>
<field name="submitButton" title="${uiLabelMap.CommonUpdate}"><submit button-type="button"/></field>
</form>
If you see above the ListPersons calls the service updatePracticePerson.
inside servicedef/services.xml i have the following:
<service name="updatePracticePerson" default-entity-name="Person" engine="simple"
location="component://practice/script/org/hotwax/practice/PracticeServices.xml" invoke="updatePracticePerson" auth="true">
<description>Create a Person</description>
<auto-attributes include="pk" mode="IN" optional="false"/>
<attribute name="salutation" mode="IN" type="String" optional="true"/>
<attribute name="firstName" mode="IN" type="String" optional="false"/>
<attribute name="middleName" mode="IN" type="String" optional="true"/>
<attribute name="lastName" mode="IN" type="String" optional="false"/>
<attribute name="suffix" mode="IN" type="String" optional="true"/>
</service>
In the root of my project in the file ofbiz-component.xml i have :
<service-resource type="model" loader="main" location="servicedef/services.xml"/>
this to make sure that my service is loaded.
Although all of the above seem correct to me I get the following error :
org.ofbiz.widget.screen.ScreenRenderException: Error rendering screen [component://common/widget/CommonScreens.xml#GlobalDecorator]: java.lang.RuntimeException: Error rendering included form named [ListPersons] at location [component://practice/widget/PracticeForms.xml]: java.lang.IllegalArgumentException: Error finding Service with name updatePracticePerson for auto-fields-service in a form widget (Error rendering included form named [ListPersons] at location [component://practice/widget/PracticeForms.xml]: java.lang.IllegalArgumentException: Error finding Service with name updatePracticePerson for auto-fields-service in a form widget)
Which obviously implies that everything is not ok and there is something wrong with my service. Could you please assist on this?
Thanks in advance,
gianis
Restart OFBiz and check the logs. During startup it will show you loading your component and then the services defined in your component. You should be able to see the problem in the logs
at the end i found the answer myself.
in the file on the root of my component ofbiz-component.xml i had:
<resource-loader name="personForm" type="component"/>
when I should have:
<resource-loader name="main" type="component"/>

Obfuscating source code using proguard

Instead of using the option -ignorewarnings, you should try solving the warnings that you get. You don't mention warnings in your question, but chances are that you have specified library classes (with -libraryjars) that depend on program classes (with -injars), which is not allowed. Cfr. ProGuard manual > Introduction.
