Question about Webapp sample

2004-08-16 10:55

Hi,

 

What I'm trying to accomplish is to write an applet that will allow the end user to print a report on their local printer. From what I can see, the PrinterApplet in the webapps sample will do this.

 

I've taken the code for this applet and modified it slightly, as I don't want the end users to see the report.

 

I can compile the code just fine, and everything seems to be fine when I run the HTML file in appletviewer -- but when I click on the Print button, I get the following error:

I have jasperreports-0.6.0.jar and jasperreports-0.6.0-applet.jar in my classpath, so I am a bit confused about the "Class not found" error.

 

I've also tried running the original applet, and I get the error "java.security.AccessControlException: access denied".

 

Could someone point me in the right direction? I apologize in advance for my newbie status when it comes to applets....

 

Thank you,

 

Ken Hollister

hi, i'm not sure if this applies to you too. i've got a similar error (java.lang.NoClassDefFoundError) when trying to make webapp run..

 

i tried including the .jar file in the tomcat/commons/lib directory and then the error msg changed (to another error). so maybe you could trying the same way..

 

and by the way, this is my current error, but nothing seems to help...
