UIX Submit Validation - Internal Server Error

Question

My UIX page (lean test page) contains the following code:
<contents>
<form name="test">
<contents>
<textInput text="Norbert" name="Norbert" >
<onSubmitValidater>
<regExp pattern="Norbert" />
</onSubmitValidater>
</textInput>
<submitButton text="Submit" formName="test" />
</contents>
</form>
</contents>
I try to run this page in debug mode within JDeveloper 9.0.2.x.
and get the following error (within IE)
500 Internal Server Error
java.lang.NoClassDefFoundError: oracle/cabo/ui/validate/RegExpValidater
java.lang.Object oracle.cabo.ui.xml.parse.ClientValidaterFactory$Parser.getNodeValue(...) ......
All my classpaths are set properly (I guess so).
This works fine within Apache (on my testbox), validation is working properly,
but fails within debug mode on JDev.
I assume JDev is able to load file: 'UIX2.jar' properly, because it is able to load
"oracle.cabo.ui.xml.parse.ClientValidaterFactory$Parser" (within 'UIX2.jar')
but why is JDev complaining about missing
"oracle/cabo/ui/validate/RegExpValidater"
this is within the same JAR and should be accessible.
Thanks for help

Answer 1

We need a class in the regexp.jar library. That JAR should
be available in JDev, though you can also download it
from jakarta.apache.org (Apache Regexp).
