I was playing with some free java code but I was miffed.
In the current working directory, I have xyz.jar and a subdirectory
coresrvlets. The classes of the package coreservlets are naturally all in
the subdirectory coreservlets. Furthermore xyz.jar has the library that some
of the coreservlets classes may cay on.
I can't run the ShadowedTextFrame class from the current directory with
java -classpath .;xyz.jar coreservlets\ShadowedTextFrame
nor
java -classpath .;xyz.jar;coreservlets coreservlets\ShadowedTextFrame
( I get something like
Exception in thread "main" java.lang.NoClassDefFoundError:
coreservlets\ShadowedTextFrame (wrong name: coreservlets/ShadowedTextFrame)
at java.lang.ClassLoader.defineClass0(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:486)
)
However, I could run an applet which calls the above ShadowedTextFrame from
the current directory like this
appletviewer ShadowedText.html
where ShadowedText.html has an applet tag like this
<applet
code=coreservlets\ShadowedTextApplet.class
name=ShadowedTextApplet
archive=xyz.jar
width=320
height=300 >
<param name="MESSAGE" value="TEST text shadow">
</applet>
What do I need to do so I can run the ShadowedTextFrame class directly with
the java command?
ShadowedTextFrame.java looks to me perfectly like a regular swing java
application to me with its main. and the source code is as follows
The package coreservlets;
import java.awt.*;
import javax.swing.*;
import java.awt.geom.*;
import java.awt.event.*; // for the listeners
/** Interactive interface to MessageImage class.
* Enter message, font name, and font size on the command
* line. Requires Java2.
