Hello,
I have a problem to run the next code. I have a glassfish server and I add servlet api.
The problem is when I try to run it this error occurs:
In-place deployment at /Users/jakublemiszewski/NetBeansProjects/JspServletTutorial/build/web
GlassFish Server, deploy, null, false
/Users/jakublemiszewski/NetBeansProjects/JspServletTutorial/nbproject/build-impl.xml:1077: The module has not been deployed.
See the server log for details.
The other error:
/Users/jakublemiszewski/NetBeansProjects/JspServletTutorial/src/java/Servlet/SimpleServlet.java:47: error: method getAttribute in interface HttpSession cannot be applied to given types;
session.getAttribute("savedUserName", userName);
required: String
found: String,String
reason: actual and formal argument lists differ in length
1 error
/Users/jakublemiszewski/NetBeansProjects/JspServletTutorial/nbproject/build-impl.xml:899: The following error occurred while executing this line:
/Users/jakublemiszewski/NetBeansProjects/JspServletTutorial/nbproject/build-impl.xml:321: Compile failed; see the compiler error output for details.
BUILD FAILED (total time: 0 seconds)
I'm new in this stuff so I don't understand what is the problem Hope to receive some help.
Thank you :)
