It’s the package rename for the later servlet spec. Use tomcat 9 and you’ll be fine.

Issue with tomcat version of GWT 2.11 for class javax.validation.Path

Priya <priyako...@gmail.com>: Mar 20 03:14PM +0530 Hi Team,   We are working on development environment with Tomcat 10 where third party jar *jakarta.validation-api.jar *has been updated to tomcat specific version where package structure is changed from javax.validation to jakarta.validation.   When GWT 2.11 with tomcat specific jars(Gwt-servlet and requestfactory-server.jar) are deployed, it is trying to find javax.validation.Path with below stack trace-   Exception while dispatching incoming RPC call java.lang.NoClassDefFoundError: javax/validation/Path java.base/java.lang.Class.forName(Class.java:467) at com.google.gwt.user.server.rpc.SerializationPolicyLoader.loadFromStream(SerializationPolicyLoader.java:217) at com.google.gwt.user.server.rpc.jakarta.RemoteServiceServlet.loadSerializationPolicy(RemoteServiceServlet.java:98) at com.google.gwt.user.server.rpc.jakarta.RemoteServiceServlet.doGetSerializationPolicy(RemoteServiceServlet.java:437) at com.google.gwt.user.server.rpc.jakarta.RemoteServiceServlet.getSerializationPolicy(RemoteServiceServlet.java:251) at com.google.gwt.user.server.rpc.impl.ServerSerializationStreamReader.prepareToRead(ServerSerializationStreamReader.java:505) at com.google.gwt.user.server.rpc.jakarta.RPC.decodeRequest(RPC.java:241)   As this package has been changed in our environment to jakarta.validation.path, GWT source code is unable to find this class, giving NoClassDefFoundError.   Also we can find several references of javax.validation.Path in gwt-user and other jars under GWT 2.11 jars.   My queries are - 1. Has anyone come across such error, if yes, what is workaround. 2. as javax packages are outdated and replaced by jakarta, is there a plan to update them and what is significance of those classes .Also, how this failure can be addressed. 3. One solution I could see for older releases, is to add dependency for gwt-servlet-deps.jar, but that is not viable solution to us,as we are moving away from javax packages due to tomcat upgrade.   Any immediate help will be appreciated. Thanks!
