hi,
I would like to know( if it's possible), why i've those error messages when i try to use my applet java because when i use this in an java application i've no problems.

Could not read property 'edtftp.log.level' due to security permissions
Could not read property 'edtftp.log.log4j' due to security permissions


my: java.policy.applet is

grant{
permission java.util.PropertyPermission; permission java.util.PropertyPermission "edtftp.log.level", "read"
permission java.util.PropertyPermission "edtftp.log.log4j", "read"
};



ps: I don't have error at compilation


thanks a lot!

Try adding your permissions to the java.policy file.

I'm not sure that java.policy.applet is recognized by the JRE.

Thanks for your reponse but i've found my problem before.

It was just because my archive .jar was malformed and not a policy file problem.
My applet applet work well without use a policy file.


For use edtftp librairy with an applet, your signed .jar file must contain:

- YourApplet.class
- the folder: com (issue from extracting "edtftpj-1.5.2.jar").


that's all

I have exactly the same problem as you.
And, I do not understand what your solution is.

I have tried the folowing tricks:

1.
My JAR archive (ftp.jar) contains two libraries:
- mine (com.xxx)
- edtftpj-1.5.3 (com.entreprise.dt.net, com.entreprise.dt.net.ftp, com.entreprise.dt.net, com.entreprise.dt.net.ftp.test, com.entreprise.dt.net.util.debug)

2.
My JAR archive only contains my librairy.
Here's my workspace root directory: 
.
|-- class
|   |-- com
|   |   `-- xxx ...
|   `-- java.policy.applet
|-- ftp.jar
|-- index.html
|-- lib
|   `-- edtftpj-1.5.3.jar
`-- src
    `-- com
        `-- xxx ...


The content of my HTML file is:
<html>
  <body>
  <applet archive="ftp.jar" code="com.xxx.MyApplet" width="150"  height="20">
    <param name="dossier" value="tt/" />
  </applet>
  </body>
</html>


And the error is:
Could not read property 'edtftp.log.level' due to security permissions
Could not read property 'edtftp.log.log4j' due to security permissions
java.security.AccessControlException: access denied (java.net.SocketPermission pixpoket.com resolve)

        at java.net.InetAddress.getByName(InetAddress.java:958)
        at com.enterprisedt.net.ftp.FTPClient.setRemoteHost(FTPClient.java:842)
        ...


Is it important to specify the java.policy.applet file ?
Does anybody else have a solution?
