hi
I am trying to invoke the scrapingsession from a java class file...
com.screenscraper.scraper.RemoteScrapingSession scraperSession = new com.screenscraper.scraper.RemoteScrapingSession("Shopping Site");
scraperSession.setVariable("SEARCH","dvd");
scraperSession.setVariable( "PAGE", "1" );
scraperSession.scrape();
but as soon as it encouters the like "scraperSession.setVariable("SEARCH","dvd");"
I get the message ...
java.lang.NoSuchMethodError: java.lang.String: method replaceAll(Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String; not found
at com.screenscraper.scraper.RemoteScrapingSessionCommand.replaceCarriageReturnsAndNewLines(RemoteScrapingSessionCommand.java:164)

Error while invoking Session from Java App..
Hi Athreya,
My apologies for the trouble. I'm still unable to reproduce the problem. Here are the steps I took:
1. Completely un-install screen-scraper.
2. Install version 2.6 of screen-scraper.
3. Import the "Shopping Site" scraping session. Email me if you'd like me to send you a copy. My email address is my first name at screen-scraper.com.
4. Start screen-scraper in server mode.
5. Invoke a simple Java class that runs the "Shopping Site" scraping session. The directory that contains this class also contains a copy of the screen-scraper.jar file I copied from the screen-scraper instance I installed in step 2.
The full code for my class is as follows:
import com.screenscraper.scraper.*;public class StartTest
{
public static void main( String args[] )
{
try
{
com.screenscraper.scraper.RemoteScrapingSession scraperSession = new com.screenscraper.scraper.RemoteScrapingSession("Shopping Site");
scraperSession.setVariable("SEARCH","dvd");
scraperSession.setVariable( "PAGE", "1" );
scraperSession.scrape();
scraperSession.disconnect();
}
catch( Exception e )
{
System.err.println( e.getMessage() );
}
}
}
If you follow those steps do you still get the error? Thanks for your patience and please let me know how it goes.
Best,
Todd

hi todd
I tried what you mentioned but I continue to get the same error.
I downloaded the SW 3 days ago and that is the only ver of screen-scrapper I have.
Is there any other alternative you can suggest.
I am using Ver 2.6
thanks

Hi Athreya,
This is most likely occurring because you've upgraded your instance of screen-scraper, but are referencing a slightly old screen-scraper.jar file from your Java class. Be sure that the screen-scraper.jar file you're referencing from your code is the same screen-scraper.jar file that's found in the screen-scraper installation directory.
Hopefully that does the trick. If not, please don't hesitate to post a reply.
Kind regards,
Todd Wilson
