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”:

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…

BBill,

I compiled my code properly,i verified it again
when u see little down in the error which i had send u will find transformsequence.xml also

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 can be found, this problem will go away. Please put your “transformsequence.xml” file into directory /webapps/orchestrator/samples/data
and try again.

Guest · December 30, 2002, 6:29pm

Bill i kept my transformsequence.xml in

http://localhost:8080/orchestrator/samples/data/trasformsequence.xml and item1.xsl in same location

i could access this thru browser

Regards
Dacha

Guest · December 30, 2002, 6:32pm

In your last post you mention file
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/transformsequence.xml
Was this just a typo in your posting or a real problem in your filename?

Guest · December 30, 2002, 7:00pm

Bill,

It was a typo,yes i got…there was some problem with item.xsl

Thanks a lot for all the help u extended

Dacha
