Hi Bill  
  
 I changed all that you have said,i changed these lines in java file  
  
\_url = (\_sequenceFile == null) ?  
 \_destinationURL:  
  
 \_destinationURL + “?” + SEQUENCER\_PROPERTY + “=” + \_sequenceFile;  
  
  
  
and sequence fie  
transformsequence.xml as u said  
  
  
 \< !–{Name: step};{Notes: }–\>  
  
  
  
  
  
  
i am getting error 500

First can you please continue a thread rather than starting a new one (just hit Post Reply at the bottom of the page)… but don’t worry about that for now.  
  
Second you seem to have changed your sequence xml file so that the stylesheet location is the same physical file as the sequence file. Please change it to the value I showed you in my original post:  
  
  
and then make sure that the files item1.xsl and transformsequence.xml are both in the same filesystem location (folder).  
  
If you work carefully through my previous reply I’m sure it will work, but if it still fails, please tell us what output do you have in your Component Factory window when you attempt to run your utility (please cut and paste it in reply to this message).  
  
Thanks.

So you can see from the error in the Factory window that your code is still trying to load “transformsequece.xml”:

```auto
2002-12-30 17:49:12,785 ERROR - Error getting sequence=http://localhost:8080/orc
hestrator/samples/data/transformsequece.xml
```

Have you really corrected and recompiled your code? If so I can only suggest you restart the Factory and Tomcat and try again…

OK I missed that -sorry- but it is still just a File Not Found Exception. If you make sure that the file   
[http://localhost:8080/orchestrator/samples/data/transformsequence.xml](http://localhost:8080/orchestrator/samples/data/transformsequence.xml) can be found, this problem will go away. Please put your “transformsequence.xml” file into directory /webapps/orchestrator/samples/data  
and try again.

In your last post you mention file  
[http://localhost:8080/orchestrator/samples/data/trasformsequence.xml](http://localhost:8080/orchestrator/samples/data/trasformsequence.xml)  
but the file we want to load is called  
[n[/b]sformsequence.xml]http://localhost:8080/orchestrator/samples/data/tra **n** sformsequence.xml](http://localhost:8080/orchestrator/samples/data/tra%5Bb)  
Was this just a typo in your posting or a real problem in your filename?
