Running different servlet apps with NetBeans 16
I am trying to run and debug my webapps with NetBeans 16 and Tomcat 9.0.65 (I am running OpenJDK 11 but targeting JDK 8 on macOS 10.15). Things are working, but I think there should be a better way. I have a directory ./nbdev with three subdirectories: appA, appB, and apache-tomcat-9.0.65. Tomcat is installed under Services->Servers with debug port 11550. When I run or debug either app, the context.xml files do not copy to apache-tomcat-9.0.65/conf/Catalina/localhost. I cannot run my app until I copy the context file there myself and add the docBase to the Context of each file (as in docBase="/Users/thad/nbdev/appA/target/appA##1.0.6"). When I run the first app create (appA), the context file I copied remains at apache-tomcat-9.0.67/conf/Catalina/localhost/appA.xml However when stop Tomcat and run appB, its context is deleted and must be recopied. I cannot see any difference in their Project Properties (other than General). This occurs on both my home and office Macs. -- "Hell hath no limits, nor is circumscrib'd In one self-place; but where we are is hell, And where hell is, there must we ever be" --Christopher Marlowe, *Doctor Faustus* (v. 111-13)
Re: [servlet]
Regarding "compile error that complains about that RequestDispatcher is an
undefined symbol. "
When editing, are red issue icons in the Netbeans gutter on the left on
some of the imports? This can show missing dependencies in your pom file.
May need to add the javax-servlet-api dependency.

Re: [servlet]
Now I see that this also works:
${miles} miles = ${kilometers} kilometers
I had put round braces instead of curly braces which caused the previous error.

Re: [servlet]
Thanks, Carl! I put
<%=request.getAttribute("miles")%>
and
<%=request.getAttribute("kilometers")%>
in place of $(miles) and $(kilometers) in result.jsp and it works as desired.

Re: [servlet]
Now the next step in this tutorial passes the values of variables in the java
web form to a jsp file instead of embedding them in println commands. Here is
the code that the tutorial (https://www.youtube.com/watch?v=eP9oz6ZKUXM at
Creat JavaServer Page (JSP), about 23 minutes into it) gives:
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
float miles = Float.parseFloat(request.getParameter("miles"));
float kilometers = miles * 1.61f;
request.setAttribute("miles", miles);
request.setAttribute("kilometers", kilometers);
String resultPage = "result.jsp";
RequestDispatcher dispatcher = request.getRequestDispatcher(resultPage);
dispacther.forward(request, response);
}
I get a compile error that complains about that RequestDispatcher is an
undefined symbol. After much hunting on websites for answers, I revised the
code as in the project in the git:
https://github.com/the-sanskrit-library/public.git, namely:
protected void doPost(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, IOException {
float miles = Float.parseFloat(request.getParameter("miles"));
float kilometers = miles * 1.61f;
request.setAttribute("miles", miles);
request.setAttribute("kilometers", kilometers);
String resultPage = "result.jsp";
request.getRequestDispatcher(resultPage).forward(request, response);
}
Which compiles. However, the response I get give the string rather than their
values:
Unit Conversion Result
$(miles) miles = $(kilometers) kilometers
Any suggestions?
Yours,
Peter

Re: [servlet]
By the way, I believe these warnings are due to conflicting configuration methods. Can configure them in the descriptor or with annotations which I believe may take preference. Maybe there were some conflicting configurations in use and/or limiting the wrong place to correct. Glad it works now.

Dear Carl, Thanks for your help. I installed Tomcat version 9. Now the project runs correctly. Changing the context path to “/” however, interfered with the “It works” root app of Tomcat, so I changed it back.

Yes, the URL is correct: https://github.com/the-sanskrit-library/public.git The git directory hierarchy deceived me: I had the code outside the git directory.

Payara picks up the old version of code when I go "Debug" on a servlet
Looks like Payara is picking up the wrong version of my code when I debug a servlet from NetBeans. The work around is to go into the Admin page and undeploy the old version of the servlet. Then go back to NetBeans and try debug again. This then uses the latest version of the code. I suspect this has been a problem in the last few versions of the NetBeans/Payara combination but only now have I been able to find exactly what was happening, find a work around and articulate the problem. In trying to cure the problem, I tried many things such as deleting the NetBeans cache, deleting the .m2 cache and changing project version numbers. None of these helped. I decided to use NetBeans 12.3 and clean build. That didn’t help either ! The good news is that I’ve recompiled most of my code with 12.3 successfully with no issues. The behaviour I would have expected from the NetBeans/Payara combination is that when I go debug on a servlet, the NetBeans/Payara combination runs the latest version of my code, being the project I’ve just gone right click debug on. Has anyone else had a similar problem ? Is it a bug worth reporting or just the way Payara works ? I have kept evidence if needed. Regards David Gradwell
Web site, servlet deploy and work OK with NetBeans 12.0 beta 4 and Payara
I’ve successfully built, deployed and tested a fairly complex web site and a heavy duty servlet as Maven projects using Netbeans 12.0 beta 4. The debugger works. I’ve completed the survey. I noticed that the survey did not ask about use of native packaging. Jirka please add to the next survey ! Regards David
Allocate exception on servlet newInstance call moving from NetBeans 8 to NetBeans 11.3
Hi,
I have a large handful of servlets that were originally developed under
NetBeans 8 and Java 8, running on Glassfish 4.1.
I am now trying to move to NetBeans 11.3 and then 12.
On every one of my old servlets I can clean compile once I have changed to
libraries to javaee-web-api-8.0.jar but I always get an Allocate exception –
see below. Trying to trace through the error arises on the new instance by
name call. I’ve googled around and made sure that all my servlets have a no
parameters constructor but that doesn’t help.
I created a new project and that works.
I’ve looked at every point of comparison I can think of (constructor java code,
web.xml, build.xml, project.xml, libraries, .war contents) but can see no
difference. I’ve run under both Glassfish 5.1.0 and Payara latest version with
the same results under both. Maybe that’s not surprising since the core code
is the same. I’ve run with NetBeans on both Mac OS Catalina and Windows 10
with the same results.
I’ve kept the Java platform at 8 to avoid changing too much at once.
Looks like I will have to recreate all my servlet projects, but before I do,
has anyone had the same problem and solved it ?
Thanks
David G

Signing Java Web Servlet for Tomcat
Hello All, I am developing a Web application for deployment on a Tomcat server. I am using Netbeans 8.2 on Win7 platform for development. I have the application built sufficiently for JFileChooser to function correctly when run locally using XAMPP to save a generated database file. When the war file is built and deployed to the Tomcat server, JFileChooser does not appear to prompt for the filename. If code is remarked out and a filename is hardcoded instead then the output is generated and saved accordingly. A reference for this problem stated it was a security related issue with Tomcat server. Suggested resolution was to "sign" the applet. I have installed the plugin "Netbeans Signing" and it appears on the Tools menu list as "Sign Module". When I attempt to use it, first prompts for a project "module". I have not been able to locate any directory that will function here. There was also mentioned an option on the Tools menu list for "Keystores". However, I have not located that item either. I do have my certificate file (.p12) imported into the Windows storage for my personal identification certificate that I use for signing other documents, messages and encrypting messages. Are there any resources available that demonstrate how to sign a web servlet in Netbeans to deploy on a Tomcat server for a Java Web application? Sorry about length of message but certs are always a complicated issue. thank you, James - To unsubscribe, e-mail: users-unsubscr...@netbeans.apache.org For additional commands, e-mail: users-h...@netbeans.apache.org For further information about the NetBeans mailing lists, visit: https://cwiki.apache.org/confluence/display/NETBEANS/Mailing+lists
