calling java object from cf

[shahzad]

Hi there, I am trying to call a java object from cf script but its not
working. I know the class should be in web_root/WEB-INF/classes folder and i've
my class in C:\Program Files\Apache Group\Apache2\htdocs\WEB-INF\classes
folder. where C:\Program Files\Apache Group\Apache2\htdocs\ is the web-root.
thats wut web-root means in this case, doesnt it? so ya, i get the error
'Object Instantiation Exception. Class not found: extractor' I tried putting
this class in another folder and put that path in the classpath in the
administrator and that worked fine, but the problem with this method is that, i
would've to restart the cf server everytime i compile my java file. any
suggestions? thank you

And is that directory in the classpath?

I'm not quite sure what you mean, here.

But you can tell CF to reload class files every time, instead of caching
them in RAM. in your jrun-web.xml file, change the <reload /> node to be
true.

Hi thanks for the direct Sarge, that worked fine :) I don't have <reload />
tag in jrun-web.xml file Adam. Would you mind telling me how i can put that tag
in the file? i really don't want to restart the cf server every single time I
do a new compile of my Java code. I don't know any XML. thank you very much
for your help guys

Sarge:
Any idea why your posting never made it onto the NNTP feed? I got everything
else in the thread, just not your one. Odd.

Has anyone at Macromedia confessed to be responible for administration of
these forums yet?

This is my jrun-web.xml file. Theonly change I have made from the one that
installs by default is uncommenting the <reload /> and <compile /> nodes.
Yours will be similar, I should have thought...

nope, that didn't seem to do anything, I still had to restart cfserver to see
the new change. Following is my jrun-web.xml file

***BUMP***

I am having this exact same issue, both in Windows with CF 7.0 and Unix with CF 6.1.

Anyone have any more feedback on this issue?
