Hi,
<div class=""><br class="">
</div>
<div class="">Thx for the quick reply. We’re testing on MP 4.4 - openjdk 17. I see there’s indeed some collision</div>

<div class="">Hi Davy</div>
<div class=""><br class="">
</div>
<div class="">It always helps when you state the midPoint version you use, especially when there is a dependency clash like this. In this case, the QName class MP uses is the one from JDK (either 11 or 17, both have it), and it seems there is another one sneaking
in with the connector.</div>
<div class="">Check the connector JAR for dependencies, I guess they are under <strong class="">
lib</strong> inside the JAR. You can also try to search for the class in IDEA (I guess that's what you use from the snippet format below), use Ctrl+N, QName, Ctrl+N again if needed, to see non-project classes - you will see the dependency on the right:</div>

<div class="">Now, some of these can be OK - as they are in different packages, but if there is some older non-compatible version with the same fully-qualified name, there can be trouble. You have to exclude that library. In the worst case, Axis 2 stack will
not play well with MP at all. We used CXF for previous WS in MidPoint.<br class="">

<div data-marker="__QUOTED_TEXT__" class="">Hi,

<div class="">I have an issue with a connector were currently developing. It uses axis2 WSDL2JAVA to generate stub classes for accessing SOAP endpoints. During building tests work flawlessly, but we’re not able to use it within midpoint. There seems some kind
of clash between objects:</div>

<div class="">We tried adding some exclusions to our pom.xml file but this does not help. Does anyone have an idea how to fix this? We don’t have much experience with java development. Our dependencies and plugin config (for axis2 1.8.0) looks like this:</div>
