At least one item must exist on Schema

Anonymous — Sat, 16 Nov 2024 14:29:52 GMT

When I try to create Metadata File xml using the wizard, I often get the following error:
"At least one item must exist on Schema"
I must have done something wrong. Could someone help me?
Also, It takes quite long time to complete the third step of the wizard(over 10 minutes for a file of few hundred lines). Any idea why? I am doing this on a laptop with 1.8Ghz CPU and 1.5GB RAM. I am running Talend 2.2.2 on Windows XP.
Thanks in advance.

Hi
Can you show your xml file?

It takes quite long time to complete the third step of the wizard(over 10 minutes for a file of few hundred lines). Any idea why? I am doing this on a laptop with 1.8Ghz CPU and 1.5GB RAM.

You can allocate more memory to TOS by modifying the TalendOpenStudio.ini in <TOS_installation>
by default:

-vmargs
-Xms40m
-Xmx500m
-XX:MaxPermSize=128m

with 1.5GRAM, you can try

-vmargs 
-Xms512m 
-Xmx512m 
-XX:PermSize=128m 
-XX:MaxPermSize=128m

Best regards

hello,
i also have the same problem. it seems that that feature only works with highly simplified XML. if a schema is referenced (with a NS identifier) and that schema is not accessible by talend, will that cause the xml metadata function to stop working? this is a HUGE probem and is holding us up from using TOS to progress our workflows (
