FullTextEntityManager fullTextEntityManager = Search
.createFullTextEntityManager(em);
String temp = "message";
QueryParser parser = new MultiFieldQueryParser(
new String[] { "message"}, new StandardAnalyzer());
Query query = null;
org.apache.lucene.search.Query luceneQuery= null;
try {
luceneQuery = parser
.parse(getSearchString());
} catch (ParseException parEx) {

Hi,

shouldn't

Code:
return ( (FullTextEntityManager) em ).createFullTextQuery(luceneQuery, InstantMessage.class);


actually be

Code:
return fullTextEntityManager.createFullTextQuery(luceneQuery, InstantMessage.class);

Hi Hardy,

Hope this will help you to understand my problem :)

Code:
             FullTextEntityManager fullTextEntityManager = Search
            .createFullTextEntityManager(em);
      
      List<InstantMessage> instantMessages = em.createQuery(
            "select o from InstantMessage as o").getResultList();
      for (InstantMessage instantMessage : instantMessages) {
      
            fullTextEntityManager.index(instantMessage);
         }
      FullTextQuery fullTextQuery= getData();
      javax.persistence.Query hibQuery= fullTextQuery;
       List<InstantMessage> result = hibQuery.getResultList();
      




Code:
public FullTextQuery getData() {
      FullTextEntityManager fullTextEntityManager = Search
            .createFullTextEntityManager(em);
      String temp = "message";
      QueryParser parser = new MultiFieldQueryParser(
            new String[] { "message"}, new StandardAnalyzer());
      Query query = null;
      org.apache.lucene.search.Query luceneQuery= null;
      try {
         luceneQuery = parser
               .parse(getSearchString());
      } catch (ParseException parEx) {
         parEx.printStackTrace();
      }
      return fullTextEntityManager.createFullTextQuery(luceneQuery, InstantMessage.class);
   }





Code:
@Entity
@Indexed
@Analyzer
@Table(name = "INSTANTMESSAGE")
public class InstantMessage implements Serializable {
@DocumentId
   @Id
   @GeneratedValue
   @Column(name = "INSTANTMESSAGEID")
   long id;

@Column(name = "MESSAGE", unique = false, nullable = false, length = 50)
   @Field(index=Index.TOKENIZED, store=Store.NO)
   String message;   

getter and setter.......




Any Idea Now :)

you could try using

Code:
@In FullTextEntityManager em;

to get a FullTextEntityManager, no need for casts or calling the Search wrapping method.

Still no luck :( :(

this time i tried with the SOP's here are the details of it


FullTextEntityManager fullTextEntityManager = Search
.createFullTextEntityManager(em);

List<InstantMessage> instantMessages = em.createQuery(
"select o from InstantMessage as o").getResultList();
for (InstantMessage instantMessage : instantMessages) {

fullTextEntityManager.index(instantMessage);
}
System.out.println("getData() "+ getData());
FullTextQuery fullTextQuery= getData();
System.out.println("fullTextQuery " + fullTextQuery);
javax.persistence.Query hibQuery= fullTextQuery;
//Line where i am getting error
List<InstantMessage> result = hibQuery.getResultList();






public FullTextQuery getData() {
FullTextEntityManager fullTextEntityManager = Search
.createFullTextEntityManager(em);
String temp = "message";
QueryParser parser = new MultiFieldQueryParser(
new String[] { "message"}, new StandardAnalyzer());
Query query = null;
org.apache.lucene.search.Query luceneQuery= null;
try {
luceneQuery = parser
.parse(getSearchString());
} catch (ParseException parEx) {
parEx.printStackTrace();
}
System.out.println("luceneQuery" + luceneQuery);
return fullTextEntityManager.createFullTextQuery(luceneQuery, InstantMessage.class);
}


Output

getData() test
luceneQuery message:test
fullTextQuery org.hibernate.search.jpa.impl.FullTextQueryImpl@b930e4

and the error
Caused by: java.lang.ClassCastException: org.jboss.seam.persistence.FullTextHibernateSessionProxy
at org.hibernate.search.impl.FullTextSessionImpl.<init>(FullTextSessionImpl.java:70)
at org.hibernate.search.Search.createFullTextSession(Search.java:21)

Can you tell us which versions of HSearch and Seam you are using?

Seam

jboss-seam-debug-2.0.0.GA
jboss-seam-ui-2.0.0.GA

Hibernate

<groupId>org.hibernate</groupId>
<artifactId>hibernate-search</artifactId>
<version>3.0.1.GA</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-annotations</artifactId>
<version>3.3.0.ga</version>
</dependency>

I imagine you are using JBoss AS 5, can you try

http://www.hibernate.org/446.html#A6
When I run Hibernate Search in JBoss AS 4.2, I get a NoSuchMethodError?
