iterate mediator barfs on medium sized messages

[Harm Verhagen-4]

Hi,


I was trying to use the iterate mediator in a similar way as shown in [1]
I read xml files from disk, then process them in a sequence.

[1] http://www.slideshare.net/wso2.org/wso2-scenarios-esb-webinar-july-1st

When using tiny messages things work fine, but when using

for example:
<?xml version="1.0" encoding="utf-8"?>
<XXXRelations>
  <Relations>
    <Relation>
   <Relations>
    <Relation>
      <r_code>55267</r_code>  
    </Relation>
    <Relation>
      <r_code>55267</r_code>  
    </Relation>
  </Relations>
</XXXRelations>

 This results as expected in a sequence of messages.


However when I have an xml file with just 2 a bit larger<Relation/> parts (60 lines each). the iterate mediator refuses to work.

I get the following error:
2009-08-06 10:37:46,435 [-] [vfs-Worker-2] DEBUG LogMediator End : Log mediator

What is going on here ?
Am I using the Iterate mediator in a way its not supposed to be used ?
(The manual is quite brief about this type of iterator, but I guess this is exactly the job it is intended for, right ?)

Subject: iterate mediator barfs on medium sized messages
To: esb-java-user@...


Hi,


I was trying to use the iterate mediator in a similar way as shown in [1]
I read xml files from disk, then process them in a sequence.

[1] http://www.slideshare.net/wso2.org/wso2-scenarios-esb-webinar-july-1st

When using tiny messages things work fine, but when using

for example:
<?xml version="1.0" encoding="utf-8"?>
<XXXRelations>
  <Relations>
    <Relation>
   <Relations>
    <Relation>
      <r_code>55267</r_code>  
    </Relation>
    <Relation>
      <r_code>55267</r_code>  
    </Relation>
  </Relations>
</XXXRelations>

 This results as expected in a sequence of messages.


However when I have an xml file with just 2 a bit larger<Relation/> parts (60 lines each). the iterate mediator refuses to work.

I get the following error:
2009-08-06 10:37:46,435 [-] [vfs-Worker-2] DEBUG LogMediator End : Log mediator

What is going on here ?
Am I using the Iterate mediator in a way its not supposed to be used ?
(The manual is quite brief about this type of iterator, but I guess this is exactly the job it is intended for, right ?)

2.1.0  seems to work fine.

Do you recall what the problem was ?
Was it a synapse problem ?

Do you have a workaround for 1.7.1 ?

OK,

I'll give it a try on 2.1.0.
In the meanwhile it looks similar to https://www.wso2.org/jira/browse/ESBJAVA-496 (may/2008) which seems to be open. What do you think ?


Regards,
Harm
