Subject Problem with Postgresql jdbc connection
Date Tue, 11 Jun 2002 21:22:13 GMT
Hello,

I am trying to use a jdbc connection to Postgresql and I have some problems
with the security manager (?).
Every access to the database gives me an abort of the transaction with a 
stack trace :

----------------------------------------------------------------------------------------------------------------------------------
Apache Tomcat/4.0.3
ACCESS Erreur connection : ==Something unusual has occured to cause the 
driver to fail. Please report this exception: Exception: 
java.security.AccessControlException: access denied 
(java.net.SocketPermission localhost resolve)
Stack Trace:

------------------------------------------------------------------------------------------------------------------------------------------

The line 46 in my class (database.access) looks like :

    44       try
     45       {
     46         db = DriverManager.getConnection(url, username, password);
     47       } catch (SQLException se)
     48         { ret = 1;
     49           System.out.println("ACCESS Erreur connection : " + "=="  
+se+ "==");
     50           return;
     51         }
     52     }

That class is OK when called through a "terminal screen", the connection is OK
and all wnet well.

I look at the "security" properties in the "catalina.policy" file, but I 
can't find the good value for the parameters, even if I give all permissions 
to the  jdbc.jar ..... with :
 
 grant codeBase "file:/var/lib/tomcat4/webapps/myapps/WEB-INF/lib/pgjdbc2.jar"
 {   permission java.security.AllPermission;
 };

I can't find the right "codebase" to apply the "grant" ?????. 

Any help is wanted ...

Regards

JP Pozzi
