I just installed NetBeans 16 on a MacBook Pro with an M chip: Product Version: Apache NetBeans IDE 16 Java: 19.0.1; OpenJDK 64-Bit Server VM 19.0.1 Runtime: OpenJDK Runtime Environment 19.0.1 System: Mac OS X version 13.0.1 running on aarch64; UTF-8; en_US (nb)
I am trying to create a minimal servlet and war file to use with Tomcat apache-tomcat-10.0.23 I worked through half of the demo How to create a webapp tutorial at: https://www.youtube.com/watch?v=eP9oz6ZKUXM which, however, uses NetBeans 12 and other older software than I have installed. I was able to do the first item successfully with minor adaptations: 1. Create a Jave Web project with Maven Got build error: https://stackoverflow.com/questions/66920567/error-injecting-org-apache-maven-plugin-war-warmojo Went to: https://maven.apache.org/plugins/ Answer: manually configuring one of the recent war plug-ins in POM.xml Changed 2.3 to 3.3.2 Then got the form. I successfully created the Unit Conversion form which opens in Safari (Version 16.1) in tomcat: http://localhost:8080/mavenproject3/ But trying the second—third items: 2. Create Java Servlet & JavaServer Page (JSP) 3. Run Java Web App on Tomcat inside NetBeans I got stuck. When I fill in a value in the miles box and click Convert to kilometers, Safari gives me a HTTP Status 404 – Not Found Message The requested resource [/mavenproject3/convert] is not available Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists. After a couple of days trying to fix it, I’m still at a loss. I did get rid of a problem not finding the native tomcat libraries: INFO [main] org.apache.catalina.core.AprLifecycleListener.lifecycleEvent The Apache Tomcat Native library which allows using OpenSSL was not found on the java.library.path: ... by dowloading and installing The Apache Tomcat Native library following instructions here: https://formulae.brew.sh/formula/tomcat-native However, I still get the 404 not found in Safari. Can anyone help me? I wonder whether these debugger messages indicate a problem using a symbolic link to my real tomcat directory from /Library/Tomcat 16-Jan-2023 11:15:13.009 INFO [main] org.apache.catalina.startup.VersionLoggerListener.log Command line argument: -Dignore.endorsed.dirs= 16-Jan-2023 11:15:13.010 INFO [main] org.apache.catalina.startup.VersionLoggerListener.log Command line argument: -Dcatalina.base=/Library/Tomcat 16-Jan-2023 11:15:13.010 INFO [main] org.apache.catalina.startup.VersionLoggerListener.log Command line argument: -Dcatalina.home=/Library/Tomcat but the infos in the debugger do tell me that it is using the real directories: CATALINA_BASE: /usr/local/apache-tomcat-10.0.23 CATALINA_HOME: /usr/local/apache-tomcat-10.0.23 I get the following debugger WARNING: WARNING [http-nio-8080-exec-10] org.apache.catalina.startup.HostConfig.deployDescriptor The path attribute with value [/mavenproject3] in deployment descriptor [/usr/local/apache-tomcat-10.0.23/conf/Catalina/localhost/mavenproject3.xml] has been ignored Trying to follow suggestions at: https://stackoverflow.com/questions/11731377/servlet-returns-http-status-404-the-requested-resource-servlet-is-not-availa I’m lost. I can’t even figure out which versions of Servlet I’m using, and the instructions to find out at.: https://stackoverflow.com/questions/3913485/how-do-i-know-what-version-of-servlet-api-jar-i-have don’t provide enough context for me to know where to put the commands suggested. === Can anyone help me either (a) work through this tutorial with current versions of software, or (b) give me an example of how to create a servlet or portable war file in NetBeans to use with Tomcat by copying it to its webapps directory using current versions of NetBeans and other software?
