Re: [servlet]

[Eric Bresie]

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.

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]

[Peter Scharf]

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.
Yours,
Peter

Re: [servlet]

[Peter Scharf]

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]

[Eric Bresie]

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.  I get the correct result of 
the conversion servlet at the path http://localhost:8080/mavenproject3/convert.
Yours,

Does anything show up in tomcat log?

I seem to recall there is some migration going on to move namespace from
Java EE to jakarta EE name space.  Not sure if maybe that is coming into
play here.  This might help if it is impacted

 I just installed NetBeans 16 on a MacBook Pro with an M chip:

 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:

 Tomcat Native library which allows using OpenSSL was not found on the

 following instructions here:

 However, I still get the 404 not found in Safari.
 Can anyone help me?

Re: [servlet]

[Carl Mosca]

It opened (automatically) here for me: http://localhost:8080/mavenproject3/

Servlet says the urlpattern is “/convert”

Try

Re: [servlet]

[Peter Scharf]

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.  I have now moved it into the git directory.
Forgive me; I’m not very familiar with git and am using the desktop version.
Yours,
Peter

Re: [servlet]

[Peter Scharf]

Thank you for suggesting to put the project on Github.  I have now created a 
public repository at the following url:

https://github.com/the-sanskrit-library/public.git

The project is in the NetBeans directory.
