https://answers.axonivy.com/questions/4451/axis-web-service-client-calls-linkageerror-with-policy<p>Since Axon.ivy 8.0 you may have problems with AXIS web service client calls, which you will notice in the log as follows:</p> <pre><code>LinkageError: loader constraint violation: loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @4797c3e2 wants to load class org.apache.neethi.Policy. A different class with the same name was previously loaded by org.eclipse.osgi.internal.loader.EquinoxClassLoader @59b5251d. (org.apache.neethi.Policy is in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @59b5251d, parent loader 'platform') </code></pre> <p>This problem occurs in combination with web service policies. To fix this issue, you need to migrate to the CXF Web Service Client technology - the AXIS stack is deprecated.</p> <p><img alt="alt text" src="https://answers.axonivy.com/upfiles/1583991754-603005-image.png"></p> <p>We have invested heavily in the new CXF technology in the Web Service Call Stack . If you have any problems with CXF, please contact us. We will take our time and make the CXF stack even better 💪!</p>enTue, 30 Jul 2024 06:34:09 -0000
