Hello,
I'm trying to write an applet which accesses sessionbeans...
I first made some servlets to test all the beans I made and that works fine.
But i can't get it work with an applet...
Have done the following steps:
- i created an directory where all jar files are put
(JNDI,EJB,JONAS,JTA,JDBC,RMI,all beans)
- In the source code you see that I use Codebase tot determine the host
- in the html I set codebase="/classes" where all jar files are put:
<applet code="LoginApplet.class" codebase="/classes" width="400"
heigth="400"></applet>
First i started the rmiregistry en EJBserver
When i start the applet i don't get any errors it initialises the applet,
but it does not do any transaction...
Can someone tell me what is missing?
Thanks
Best Regards,
Jochen Vastmans
