data import handler issue

[Tanweer Noor]

Hi,
I am having issue in fetching records from db, I am using *eXist* database.
Please see if you can help in looking into this.

http://localhost:8983/solr/dataimport?command=full-import


 -  <
response>
 -  
   0
   0
   
 -  
 -  
   data-config.xml

   0:0:0.219
  
   This response format is experimental. It is likely
to change in the future.
  

below is my data-config.xml file




http://localhost:8081/exist/servlet/db/dbname/?_query=for%20$p%20in%20//Music%20return%20$p
"
processor="XPathEntityProcessor"
forEach="/data/store"
transformer="DateFormatTransformer">
 
   
  

  
  
  
  
  
  

 
 






If i go to URL, I can see that it is fetching record from database but
somehow, solr is not fetching a single row.

http://localhost:8081/exist/servlet/db/dbname/?_query=for%20$p%20in%20//Music%20return%20$p

solr indexing on same set of records with different value of unique field...not working...

[Noor]

hi,

I need to run around 10 million records to index, by solr.
I has nearly 2lakh records, so i made a program to looping it till 10 
million.
Here, i specified 20 fields in schema.xml file. the unoque field i set 
was, currentTimeStamp field.
So, when i run the loader program (which loads xml data into solr) it 
creates currentTimestamp value...and loads into solr.


For this situation,
i stopped the loader program, after 100 records indexed into solr.
Then again, i run the loader program for the SAME 100 records to indexed 
means,

the solr results 100, rather than 200.

Because, i set currentTimeStamp field as uniqueField. So i expect the 
result as 200, if i run again the same 100 records...


Any suggestions please...

Noor

Need to know about Custom request with filters in solr ?????

[Noor]

Hi,
  We're working on apache solr. We need some feature for appending 
some constraints(filters) with incoming solr query(request). The solr 
should response for the incoming query with the specified constraints 
meets.
We made the posting operation in java, it retrieved all the sql data and 
make it as xml;
Then it performs indexing and storing into solr data.

AttachDebugger in Netbeans, for solr ???

[noor]

hi,
i am new to solr.
I am having the solr package, and it starts running in my pc.
I created the custom handler class as a java project through Netbeans.
  And i put that jar in solr webapps's lib folder; and in 
solr-config.xml also i changed. before solr gets started.
What i need to do is debugging. I dont know about Netbeans 
Attach-Debugger facility.???


How do we use Netbeans attach-debugger facility, to debug my code, when 
solr runs...???

Re: Custom Request handler Error:

Also, how to make the update, through url, i mean,

Yes, i changed "custom" into "/custom", now it calls my class.

I solved this NullPointerException, by the following changes.

In java code:

.
}

and in solr-config.xml:


explicit

true



Now, my webapp runs fine by,
http://localhost:8983/mysearch
searching also working fine.
But, these are not run through my custom handler. So i felt, it 
wrongly

doing searching.
Because, in solr admin statistics page,
my custom handler under QueryHandler's request count remains 0, it
doesn't
get incremented, when i search something. Rather, 
statndardReqHandler's

request count is incremented.

And another thing, how do we debug solr. ???
Please anybody help me to solve this ...

Thanks in advance.

Yes Mark Miller,
I changed the Connector specification in attach-debugger dialog,

Now i got the netbeans debugger-console output as,

But, nothing will be display after that, but the progress shows,

Make a file next to build.xml called build.properties.

Add to the empty file: example.debug=true

Run the ant target 'run-example' in build.xml.

Solr will run with the ability to connect with a remote 
debugger on port 5005.


In Netbeans, from the main menu, select Debug > Attach 
Debugger... (In NetBeans 6.1 and older select Run > Attach

Make a file next to build.xml called build.properties.

Add to the empty file: example.debug=true

Run the ant target 'run-example' in build.xml.

Solr will run with the ability to connect with a remote debugger on 
port 5005.


In Netbeans, from the main menu, select Debug > Attach Debugger... 
(In NetBeans 6.1 and older select Run > Attach Debugger...).


Follow the dialogue box prompts to connect to the running Solr example.

Re: Debug Solr in Netbeans..

[noor]

Solr starts running in the port 8983,
i created build.properties in the project folder, where the build.xml is.
And in that empty build.properties file,
i added,
example.debug=true
only.
And in Netbeans, Debug -> Attach Debugger,
- Debugger is JavaDebugger(JPDA);
- Connector is SocketAttach(Attaches by socket to other VMs)
- HOST is localhost;
- Port as 5005;
and Timeout is empty.

During solr running, i set this, but in the output screen shows 
"Connection is refused."


Is my changes are correct ??? or i need to change anything else...


thanks and regards,
Noor

Re: Custom Request handler Error:

Specify the full package to your handler class. Packages starting with
"solr" are loaded in a special way.

  
I specified like

But still the same error.
