Java Security Problem

[Thomas Dandelot]

Hi all,   I'm using entity beans with Orion and got some strange messages while calling a Remote method on one of them : Exception occurred during event dispatching: java.security.AccessControlException: access denied (java.io.SerializablePermission enableSubstitution)         at com.evermind._dn.EXCEPTION_ORIGINATES_FROM_THE_REMOTE_SERVER(.:1446)         at com.evermind._dn.invokeMethod(.:1369)         at com.evermind._yd.invoke(.:53)         at com.evermind._jdb.invoke(.:22)   On server side, I also have an exception, almost at the same time :   java.security.AccessControlException: access denied (java.io.FilePermission ./database/defaultdb.script.new delete)         at java.security.AccessControlContext.checkPermission(AccessControlContext.java:272)         at java.security.AccessController.checkPermission(AccessController.java:399)         at java.lang.SecurityManager.checkPermission(SecurityManager.java:545)         at java.lang.SecurityManager.checkDelete(SecurityManager.java:1005)         at java.io.File.delete(File.java:709)         at org.hsql.Log.writeScript(Log.java:432)         at org.hsql.Log.close(Log.java:147)         at org.hsql.Database.close(Database.java:586)         at org.hsql.Database.processShutdown(Database.java:603)         at org.hsql.Database.execute(Database.java:127)         at org.hsql.jdbcConnection.executeStandalone(jdbcConnection.java:686)         at org.hsql.jdbcConnection.execute(jdbcConnection.java:541)         at org.hsql.jdbcConnection.closeStandalone(jdbcConnection.java:677)         at org.hsql.jdbcConnection.close(jdbcConnection.java:277)         at com.evermind._hi.close(.:92)         at com.evermind.sql.OrionPooledDataSource._ape(.:424)         at com.evermind.sql.OrionPooledDataSource.run(.:380)         at com.evermind.sql.DriverManagerXADataSource.run(.:173)         at com.evermind._bq.run(.:133)         at com.evermind._bs.run(.:64)   I thought it was a security problem so I changed my java.policy to all permissions like this (both in server and client side) : grant {  permission java.security.AllPermission; };   But the same problems occur all the time. Does anybody know from where this error comes from ? Did anybody already have this problem ? How could I solve it ? Any help would be really much appreciated, this is urgent.   Thanx,                                 Thomas Dandelot
