Could you be more specific about your usecase? What version of Search are you using and what's your setup? How does your code look like?
BTW, could it be a session problem?

--Hardy

i am using lucene 2.4.1
here is my hibernate search code and hibernate confugarion
this is my search code
public List search1(String name1,String scat,String cat,int pageNumber)

{

//indexWithHibernate();

//createSomeArticles();
Session session = HibernateUtil.currentSession();
System.out.println("i am in method"+session);
fSession = Search.getFullTextSession(session);
System.out.println("Session test"+fSession);
fSession.beginTransaction();

// create a parser to parse a full text query
QueryParser parser = new QueryParser("name", new StandardAnalyzer());
int id=Integer.parseInt(cat);
System.out.println("parser"+parser);

try {
lucenceQuery = parser.parse(scat+":"+name1+"*"+" OR catpojo.id :"+id);
System.out.println(lucenceQuery);
} catch (ParseException e) {
throw new RuntimeException("Cannot search with query string",e);
}




System.out.println(lucenceQuery+ " "+fSession);
FullTextQuery fp=fSession.createFullTextQuery(lucenceQuery,MovieMasterPojo.class);System.out.println(" size1"+fp.getResultSize());
/////////here only i am getting problem...
fp.setFirstResult(pageSize * (pageNumber - 1)) ;
fp.setMaxResults(pageSize) ;

this.setTotal(fp.getResultSize());
List<MovieMasterPojo> articles = fp.list();
fSession.getTransaction().commit();
System.out.println(" size2"+articles.size());
return articles;
}

please come with good idea

Your code seems a little messy, but on the first glance it should work.
Looking at your original stacktrace you seem to use Struts2. The error you are posting is probably from the web browser. Is there any more information in the tomcat log?

I also can't see yet what you mean with:"problem comes when the request is going through some other page.". Do you have an Action forward or what are you talking about?

--Hardy

no exceptions in tomcat logs.
But my problem is, my search application(using struts2)is working fine as a standalone.but if i give the link (common hyperlink)in my application it is throwing an exception called
INDEX ALREADY BOUND EXCEPTION:Index already closed..

Given that your code works standalone I suspect some sort of session setup problem in your webapp. Do you use the Open Session in View pattern?
Where is your HibernateUtil class coming from?

For a sample setup for a Struts2 application using Hibernate/JPA see - http://cwiki.apache.org/WW/struts-2-spr ... -ajax.html

Are you using something like OpenEntityManagerInViewFilter in your web.xml? If you think your setup is correct, could you provide a sample war file demonstrating the problem?

--Hardy

yes i am using session view pattern for getting session...i am not using any JPA in my application...i am giving my HibernateUtil and web.xml..
please check it and give me the solution....
