Hi, I’ve used getElementsCount in 7.8.2 with no problem. Today we decided to upgrade to 8.1.0 on a newer machine and run our scripts. The scripts fail on getElementsCount, and following error is displayed. Please help! ❌ Unable to get element count (Root cause: java.lang.LinkageError: loader constraint violation: when resolving field “NODE” the class loader (instance of org/codehaus/groovy/tools/RootLoader) of the referring class, javax/xml/xpath/XPathConstants, and the class loader (instance of ) for the field’s resolved type, javax/xml/namespace/QName, have different Class objects for that type ---

Hi @mqamar, Please share with us the .classpath file which is under the root folder project. ---

Thank you so much for a response. I did read this post, however, the response wasn’t clear for me. How and from where do I remove the stax-api-1.0.1.jar file? I see the stax-api-1.0.1.jar file mentioned in the .classpath, do I remove it from there? Earlier I removed the .classpath, bin, lib, .project folder but that didn’t help either. How does one remove the stax-api-1.0.1.jar file from katalon? ---

> [@mqamar](#): > > I see the stax-api-1.0.1.jar file mentioned in the .classpath, do I remove it from there? This. In the .classpath file you can find the exact full path of the stax-api-1.0.1.jar. You should remove the file at the path. > [@mqamar](#): > > Earlier I removed the .classpath, bin, lib, .project folder No harm to remove them, but it is not what you need to do now. ---

After removing stax-api-1.0.1.jar file from the .classpath and the folder where Katalon extracted the files, my code finally worked. Basically I searched for this jar file on my machine, and deleted it from all the places under my soap project.
