Hi, im a new member here although i have been lurking for a few years!
Im not sure if this is the correct sub forum to be posting in and i apologize if it is not.
I have created a javaapplet which is linked to a database in MySQL. It queries and updated the tables within depending on user interaction.
My applet runs fine from within Eclipse but i seem to be running into a similar problem to many others. I have looked over MANY threads on this problem but have yet to find a definitive answer/solution. They all seem to differ. I have picked up information from these threads but i am still a bit confused. When i open my applet through a html file nothing happens, no error messages, nothing. I have commented out my code and just painted a line of text and it works, so i dont believe its my html file thats the issue. What i would like to know from you gurus is:
1. Do i have to create a jar (i have tried this but is it necessary?)
2. Do i have to get my applet signed to enable the database interaction whilst running in a browser?
3. Could there be another reason why my applet will not load?
This is extremely frustrating! It will eventually be placed on a server along with the database.
I can post the code if required, although it has quite a high amount of lines. Any help would be GREATLY appreciated!
Applets are very limited in what they can do. They can't access the local file system, or any networked resource other than the server it's downloaded from. If you want to do something like this you will need to create a signed JAR file. So that would be a "yes" to both questions 1 and 2.
