Class file location

Question

I am not sure if this would be an admin type question but
here goes:
I have a Coldfusion 6.1 server riding on Weblogic 8 ish and I
am trying to do a small java example... *sigh*
I am getting a "class not found" error and so I went looking
for my classpath, since it didn't seem to be what was default in
the documentation. *sigh*
So I find that it is defaulting to .jar files and no
directories. I can see that there are class files that are out in
our coldfusion land so how does it see these? I am pretty ignorant
of weblogic. I was curious how they can be reading the files, if
they are, when the paths that I see only point to jar files. So, no
explanation is too simple, please use small words and type slow for
me. How should/do I change the path since I have to change it in
Weblogic not CF admin. Is there some kind of default folder I am
missing? I even tried adding my class to cfclasses under the cf
file directory. Any help (and I need a lot) would be greatly
appreciated.
Thank you in advance for your infinite patience and any help
you can provide!!!

Answer 1

I f you want to try the jar method, here's a quicky on how to
jar up your file as a package.
in a work folder, create a folder structure for your package,
convention uses reverse internet domain (i.e.
com.adobe.packagename)
for this one, we'll use a simple one level package called
ironyx. So create a folder called ironyx.
copy the java file you want to package up into the ironyx
folder
at the top of the java file place the following;
package ironyx;
Compile the java file.
Using a command prompt in the parent folder of the ironyx
folder, type the following;
jar -cf ironyx.jar ironyx
This will jar up the ironyx folder contents, including both
the java and class files into an ironyx.jar file. You can delete
the source java files prior to creation of the jar file if you
wish.
Copy the jar file to ColdFusion WEB-INF\lib directory, bounce
the cf instance
A typical cf execution might look like
<cfset mySimpleMath=
CreateObject("java","ironyx.SimpleMath")>
<!--- Usually you Initialize the object, but that depends
on the constructors of the class--->
<cfset mySimpleMath.init()>
<!--- Execute the method --->
<cfset result = mySimpleMath.addNumbers(num1, num2)>
Note: If you're using the SimpleMath class file from
http://builder.com.com/5100-6370-5177283.html,
they have a text formatting error for the method. There should be
spaces in publicintaddNumbers and it should look like
public int addNumbers
