First
...
a
...
little
...
definition
...
of
...
what
...
is
...
the
...
classpath
...
:
...
The
...
class
...
path
...
tells
...
to
...
java
...
tools
...
and
...
applications
...
where
...
to
...
find
...
third
...
party
...
and
...
user
...
classes
...
or
...
libraries.
...
Most
...
of
...
the
...
time
...
it
...
is
...
a
...
suite
...
of
...
path
...
to
...
your
...
file
...
system
...
separated
...
by
...
a
...
;
...
character.
...
The
...
classpath
...
is
...
used
...
for
...
two
...
steps
...
:
...
the
...
compilation
...
step
...
(using
...
javac
...
command)
...
and
...
the
...
running
...
step
...
(using
...
java
...
command).
...
The
...
following
...
shell
...
extract
...
shows
...
you
...
how
...
to
...
run
...
the
...
demo
...
application
...
with
...
full
...
features
...
and
...
specifying
...
classpath
...
elements.
...
Therefore
...
we
...
didn't
...
choose
...
to
...
specify
...
each
...
module
...
libraries
...
one
...
by
...
one,
...
we
...
just
...
included
...
the
...

...

If

Using Eclipse IDE
There is no known issue or tip for using JFReport inside Eclipse IDE.
If you are developer and you want to work on 0.8 branch source code you will have to use the release-0_8_7-branch
...
tag
...
as
...
you
...
could
...
see
...
on

this

Otherwise you just need to include the required libraries to the classpath of your project. Right click on your project and Build Path then Configure Build Path:
Using IntelliJ IDE
The only one known issue using IntelliJ if you plan to be a JFreeReport developer (working with sources) is to add some file patterns in .... to be copied over the compile directory. The patterns to add are *.css and *.txt. Here is how it look like:

Webapp
There is nothing to say as I could see
Applet
A Java applet is small application served by a web server and running inside the client web browser virtual machine. You also have to know that to prevent illegal accesses from the applet to the client local file system, it must be signed to allow the client to verify its authenticity.
Before talking about how to sign applets, I will introduce the basis needed to make and run an applet:
An applet use the same technologies as a standard Java application (a JRE/JDK, libraries,...) but its main class must extends java.applet.Applet class. Within the web server it must be embedded into an HTML page as the following using the applet tag:
| Code Block |
|---|
<applet code="my.package.MyApplet.class" width="200" height="200" codebase="applet/">
</applet>
{code}
The {{code}} attribute is used to define the canonical applet class with the appended {{.class}} suffix. The {{codebase{}}}attribut is not mandatory (default set to ".", the calling HTML page) is used to define from where the ressources will be downloaded. As no external libraries are specified, we assume this server layout for the above example : {{_<codebase>_ |
The code attribute is used to define the canonical applet class with the appended .class suffix. The codebaseattribut is not mandatory (default set to ".", the calling HTML page) is used to define from where the ressources will be downloaded. As no external libraries are specified, we assume this server layout for the above example : <codebase>/my/package/MyApplet.class
...
If you need to specify libraries, you must do it using the archive attribute. The archive attribute is a coma separed list of jars also using the codebase attribute value to be retrieved:
| Code Block |
|---|
<applet code="my.package.MyApplet.class" width="200" height="200" codebase="applet/"
archive="jfree/jfreereport-0.8.7-10.jar">
</applet>
{code}
|
If
...
you
...
need
...
more
...
informations
...
about
...
using
...
applets
...
you
...
should
...
have
...
a look at Sun applet page.
If you planned to use Java applets and want to write and read to the client file system,...
...
you
...
have
...
to
...
package
...
it
...
into
...
a
...
jar
...
and
...
to
...
sign
...
it
...
with
...
a
...
certificate.
...
If
...
you
...
don't
...
remember
...
how
...
to
...
make
...
a
...
jar
...
from
...
your
...
classes,
...
go

In
