The best thing one can do is to set up a completely
new project, and one-by-one, add each kind of resource
to the project.  That is, add a servlet, run the Web app.
Look at the file system explorer to see what went where.
Then add a JSP and do the same.  Add a static .html file
and redirect to it from the servlet.  I know, this sounds
like too much work, and it is.  (JBuilder 5 and 6 progressively 
provide better assistance in structuring a Web app project, 
as you might expect from a rapidly evolving product.)  

Here's what I have surmised from looking at one project.
Suppose the project file (.jpr) is located in the "webOne"
folder, and other folders are as shown here:

  d:/projects
    + webOne
      + myWebApp.jpr
      + src
      | | - home.jsp
      | | - static.html
      | + com
      |   + mycorp
      |     + servlets
      |     | - servlet1.java
      |     | - ... <other servlets>
      |     + models
      |       - datamodule1.java, etc.
      + bak
      + classes
      + images
        - logo.jpg
    

In the Project Properties dialog:

Paths tab

  Working directory: d:/projects/webOne
  Source tab
    d:/projects/webOne/src

Run tab

  JSP/Servlet tab
    Start file/class: <your starting HTML or JSP>

    Servlet options tab
      Document base: d:/projects/webOne


To reference resources in JSPs or static HTML, you'd
write, for example,

html
  body
    <a href="home.jsp"><img src="/images/logo.jpg">/a
  /body
/html

Note the "/" prefix to "images/logo.jpg".  This means
that the folder "images" is in the "Document base"
folder, which was defined above as "d:/projects/webOne".

That should just about do it.
