Hi Collins   
  
 i am using j2sdk1.4.0&tomcat3.2…my problem with Log4j got solved,there was some problem with xml file…from java file i am sending one xml file and sequence file…to OrchestratorGateway, it is giving output

Hi,  
First, for some reason it seems that the code in your   
getResultsFromMediator method to build the URL has been partially commented out, so your http request doesn’t contain any information about the location of the sequence file. If you uncomment this code you should send an extra argument:  
?xbd.sequence.uri=  
with the URI and this should help.

```auto
// get the URL for HTTP protocol
_url = (_sequenceFile == null) ?
_destinationURL:
_destinationURL + "?" + SEQUENCER_PROPERTY + "=" + _sequenceFile;
```

Next, the location of the sequence file seems to contain a typo:  
MediatorUtility.getResultsFromMediator(“[http://localhost:8080/orchestrator/samples/data/transformsequece.xml](http://localhost:8080/orchestrator/samples/data/transformsequece.xml)”  
  
Shouldn’t there be an extra “n” in transformsequence.xml?  
  
Third, the location of the stylesheet in the SagTransformer step of the sequence should be (I think) a URL like this:  
  
where (in my case) item1.xsl lives in the same location as the transformsequence.xml file.  
  
Finally, the stylesheet tries to create several output elements like this:  
 **Person1 details**   
 **Person1 details**  
and it is illegal to create a DOM document like this with several root nodes. So I changed your stylesheet to wrap the output in a html tag like this:  
\<xsl:template match=“/”\>  
  
\<xsl:call-template name=“first” /\>  
\<xsl:call-template name=“second” /\>  
\<xsl:apply-templates select=“root/person” /\>  
  
\</xsl:template\>  
and now it works - I get this output:  
**Person1 details**  
ramakrishna  
cellexchangeKKK  
  
\<br/  
\> **Person2 details**   
shoban  
business  
  
  
1. **Person de  
tails**   
ramakrishna  
cellexchangeKKK  
chess  
cricket  
2.  
**Person details**   
shoban  
business  
vollyball  
tennis  
  
   
If none of this helps please let us know…
