InstantDB: Re: Version 3.13 & Network Support using RmiJDBC


Has anybody responded with an answer security policy question? I've figured
out most of them, but now I'm getting a:
Unexpected exception; nested exception is:
java.security.AccessControlException: access denied
(java.util.PropertyPermission * read,write)
I don't want to give blanket read,write property permissions. What
properties are InstantDB reading and/or writing?
BTW, This is true for 3.14 as well.

TIA,
Bill

Hi, 
I'd appreciate if someone could mail me the solution to the following
problem : 
I've installed: InstantDB version 3.13 on Sparc Solaris running Jdk1.2. 
I created the "sample" database. 
0) I move the following files into ${JAVA_HOME}/jre/lib/ext , needed amongst
other things 
one need not have these classes on the "downloaded classes" CLASSPATH. 
idb.jar 
RmiJdbc.jar 
Reason: Otherwise I run into the documented security problems with JDK1.2. 

** It would be nice if someone could say what modifications are needed in
the personal 
** ${HOME}/.java.policy file. 
1) I start the RmiJdbc.RJJdbcServer 
I am able to view the contents of the sample database with "java JDBCmain" 
using the URL: jdbc:idb:/tmp/Idb/sample.prp 
>From the screen echo I know its using : jdbc.idbDriver. 
PROBLEM: 
To confirm that I am using the RmiJdbc drivers, as opposed to the
"sun.jdbc.odbc.JdbcOdbcDriver" which is 
also loaded in "JDBCmain" (JDBCAppl), I attempt the following : 
Use of : 
1) TestClient code which arrives with RmiJdbc compiled in /somepath/ 
setenv CLASSPATH ${CLASSPATH}:/somepath 
java TestClient 
TestClient:jdbc:rmi://hostname.domainname/jdbc:idb=sample.prp 
java.rmi.UnexpectedException: Unexpected exception; nested exception is: 
java.security.AccessControlException: access denied
(java.util.PropertyPermission * read,write) 
java.security.AccessControlException: access denied
(java.util.PropertyPermission * read,write)

all.java, Compiled Code)

at java.sql.DriverManager.getConnection(DriverManager.java, Compiled Code) 
at TestClient.main(TestClient.java, Compiled Code) 
java.sql.SQLException: Unexpected exception; nested exception is: 
java.security.AccessControlException: access denied
(java.util.PropertyPermission * read,write) 
at RmiJdbc.RJDriver.connect(RJDriver.java, Compiled Code) 
at java.sql.DriverManager.getConnection(DriverManager.java, Compiled Code) 
at java.sql.DriverManager.getConnection(DriverManager.java, Compiled Code) 
at TestClient.main(TestClient.java, Compiled Code) 

2) RJAdmin code that is in RmiJdbc.jar file, and I compiled in /somepath/ 

setenv CLASSPATH ${CLASSPATH}:/somepath 
cd /tmp/Idb 
java RJAdmin PING jdbc:rmi:jdbc:idb=sample.prp 
jdbc:rmi:jdbc:idb=sample.prp] server is responding, but database connection
failed for [,] 
As you can see in both instances I fail to connect to the Database. 
In (1) it looks like some security related issue, which I thought with
moving the .jar files into jre/lib/ext/ 
would have cured, alas not. 
I've followed the instructions in "Network Support" documentation of
InstantDB : 
<http://instantdb.enhydra.org/software/documentation/network.html> 
So I would really appreciate some help on resolving this. Please do email me
the response, as I do not subscribe to 
this channel due to lack of time in reading all the messages that I have
from other channels.
