  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)
        at sun.rmi.transport.StreamRemoteCall.exceptionReceivedFromServer(StreamRemoteCall.java, Compiled Code)
        at sun.rmi.transport.StreamRemoteCall.executeCall(StreamRemoteCall.java, Compiled Code)
        at sun.rmi.server.UnicastRef.invoke(UnicastRef.java, Compiled Code)
        at RmiJdbc.RJDriverServer_Stub.connect(RJDriverServer_Stub.java, Compiled Code)
        at RmiJdbc.RJConnection.<init>(RJConnection.java, Compiled Code)
        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)
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.
