Impossible to launch the Web Service Explorer in Eclipse // Eclipse WTP / JSDK 1.7, 1.8, 21 // Win 11.
Each time I launch the Web Service Explorer it ends with:
*HTTP ERROR 500 javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/apache/el/util/JreCompat
URI: /wse/wsexplorer/wsexplorer.jsp STATUS: 500 MESSAGE: javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/apache/el/util/JreCompat SERVLET: org.eclipse.equinox.http.jetty.internal.HttpServerManager$InternalHttpServiceServlet-f345f12 CAUSED BY: javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/apache/el/util/JreCompat CAUSED BY: java.lang.NoClassDefFoundError: org/apache/el/util/JreCompat CAUSED BY: java.lang.ClassNotFoundException: org.apache.el.util.JreCompat cannot be found by org.mortbay.jasper.apache-jsp_9.0.52 Caused by: javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/apache/el/util/JreCompat at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:332) .../...*
Please help.
Other info: Windows 11 within Parallel Desktop on macOS Sonoma 14.1.2.
I tried with JSDK 1.7, 1.8, 17 & 21.
I reinstalled Eclipse 3 times, from both Java IDE version and WTP IDE. I tried to solve the issue installing several plug-ins from Eclipse repository. I added tomcat-util-9.0.0.M9.jar as external jar to the JREs.
... always the same result.
I want to use the Web Service Explorer to test the web services I am developing.
Thank you for your help. Kind regards.
