RMI and netscape
Hi all, I am dealing with security issues with netscape and plugins for linux. I am running RMI server application on my http server and trying to run applet which connect to the RMI server and server passes some information back to applet. Things works fine if i use appletviewer but not with netscape! I installed java plugins for jdk1.2 from blackdown. Applet throws netscape Security Exception on browser's java console as follows, Netscape Communications Corporation -- Java 1.1.5 Type '?' for options.

RMI JNI and objective c issue.
Hi, I have problem which enough people may not be interested but if any one can give any hint, would be appreciated. I am running objective c application using JNI starting JVM from objective c code and calling java application which uses RMI to communicate with my applet for the browser. Now the problem is, When i use simple objective code to call jvm and use RMI, it works fine but my actual application does some dynamic memory operations during runtime and so when i run with my application i get following errors, Prog Instance bound in registry SIGSEGV 11* segmentation violation si_signo [11]: SIGSEGV 11* segmentation violation si_errno [0]: Success si_code [0]: SI_USER [pid: 0, uid: 0] stackpointer=0xbedffa1c Full thread dump Classic VM (1.2.2-L, native threads): "RMI LeaseChecker" (TID:0x4133ecf0, sys_thread_t:0x82cb028, state:CW, native ID:0x 2009) prio=5 at java.lang.Thread.sleep(Native Method) at sun.rmi.transport.DGCImpl$LeaseChecker.run(DGCImpl.java:299) at java.lang.Thread.run(Thread.java:475) "GC Daemon" (TID:0x41339cd0, sys_thread_t:0x8295cd0, state:R, native ID:0x1807) pr io=2 at sun.misc.GC$Daemon.run(GC.java:95) "RMI Reaper" (TID:0x413399a8, sys_thread_t:0x8283500, state:CW, native ID:0x1406) prio=5 at java.lang.Object.wait(Native Method) at java.lang.ref.ReferenceQueue.remove(ReferenceQueue.java:108) at java.lang.ref.ReferenceQueue.remove(ReferenceQueue.java:123) at sun.rmi.transport.ObjectTable$Reaper.run(ObjectTable.java:284) at java.lang.Thread.run(Thread.java:475) "RMI TCP Accept-1" (TID:0x41339738, sys_thread_t:0x8288278, state:R, native ID:0x1005) prio=5 at java.net.PlainSocketImpl.socketAccept(Native Method) at java.net.PlainSocketImpl.accept(PlainSocketImpl.java:402) at java.net.ServerSocket.implAccept(ServerSocket.java:236) at java.net.ServerSocket.accept(ServerSocket.java:220) at sun.rmi.transport.tcp.TCPTransport.run(TCPTransport.java:291) at java.lang.Thread.run(Thread.java:475) "Finalizer" (TID:0x4132e320, sys_thread_t:0x81dab20, state:CW, native ID:0xc04) prio=8 at java.lang.Object.wait(Native Method) at java.lang.ref.ReferenceQueue.remove(ReferenceQueue.java:108) at java.lang.ref.ReferenceQueue.remove(ReferenceQueue.java:123) at java.lang.ref.Finalizer$FinalizerThread.run(Finalizer.java:170) "Reference Handler" (TID:0x4132e3b0, sys_thread_t:0x81d46d0, state:CW, native ID:0x803) prio=10 at java.lang.Object.wait(Native Method) at java.lang.Object.wait(Object.java:420) at java.lang.ref.Reference$ReferenceHandler.run(Reference.java:110) "SIGQUIT handler" (TID:0x4132e3e0, sys_thread_t:0x81d9fa8, state:R, native ID:0x402) prio=5 "main" (TID:0x4132e1e0, sys_thread_t:0x815d330, state:R, native ID:0x400) prio=5 Monitor Cache Dump: java.lang.ref.ReferenceQueue$Lock@4132E338/41364028: Waiting to be notified: "Finalizer" (0x81dab20) java.lang.ref.Reference$Lock@4132E3C0/41363B20: Waiting to be notified: "Reference Handler" (0x81d46d0) sun.misc.GC$LatencyLock@41339960/413BE920: owner "GC Daemon" (0x8295cd0) 1 entry java.lang.ref.ReferenceQueue$Lock@41339340/413BC430: Waiting to be notified: "RMI Reaper" (0x8283500) java.net.PlainSocketImpl@413393C8/413BD0E0: owner "RMI TCP Accept-1" (0x8288278) 1 entry Registered Monitor Dump: utf8 hash table: JNI pinning lock: JNI global reference lock: BinClass lock: Class linking lock: System class loader lock: Code rewrite lock: Heap lock: Monitor cache lock: owner "GC Daemon" (0x8295cd0) 1 entry Thread queue lock: owner "GC Daemon" (0x8295cd0) 1 entry Monitor registry: owner "GC Daemon" (0x8295cd0) 1 entry % Anyone know how can i secure my jvm side memory from c side?

Hi,
I am trying to implement my version
of RMISocketFactory that provides ssl sockets instead of regular sockets.
I extended RMISocketFactory as follows but compiler complains that i can
not extend it's methods!
package bank;
import java.io.*;
import java.rmi.server.*;
import javax.net.*;
import javax.net.ssl.*;
public class CGGAMPSSLSocketFactory extends RMISocketFactory
{
public Socket createSocket(String
host,int port) throws IOException{
SSLSocket socket = (SSLSocket)SSLSocketFactory.getDefault().
createSocket(host,port);
String ciphers[] = socket.getEnabledCipherSuites();
socket.setEnabledCipherSuites(ciphers);
return socket;
}
public ServerSocket createServerSocket(int
port) throws IOException {
SSLServerSocket server = (SSLServerSocket)
SSLServerSocketFactory.getDefault().createServerSocket(port);
String ciphers[] = server.getEnabledCipherSuites();
server.setEnabledCipherSuites(ciphers);
return server;
}
}
Here is the compiler complain,
black:rpatel% javac bank/CGGAMPSSLSocketFactory.java
bank/CGGAMPSSLSocketFactory.java:17: The method
bank.Socket createSocket(java.lang.String, int) declared in class bank.CGGAMPSSLSocketFactory
cannot override the method of the same signature declared in class java.rmi.server.RMISocketFactory.
They must have the same return type.
public Socket createSocket(String
host,int port) throws IOException{
^
bank/CGGAMPSSLSocketFactory.java:25: The method
bank.ServerSocket createServerSocket(int) declared in class bank.CGGAMPSSLSocketFactory
cannot override the method of the same signature declared in class java.rmi.server.RMISocketFactory.
They must have the same return type.
public ServerSocket createServerSocket(int
port) throws IOException {
^
2 errors
black:rpatel%
I am totally lost i have the same function signature as of RMISocketFactory.
Why the compiler does not like it? I would appreciate your quick
response,
Thanks,
-Raj

Thank you very much. I had import javax.net.* so i thought it is ok but actually it
requires java.net.Socket as return type and other places it requires javax.net.* So
now it works for that part but now i get following exception. Can you give me some
guideline if possible,

I have following in my code to support ssl,
java.security.Security.addProvider(
new com.sun.net.ssl.internal.ssl.Provider());
System.setProperty("java.protocol.handler.pkgs",
"com.sun.net.ssl.internal.www.protocol");
try{
RMISocketFactory.setSocketFactory(new CGGAMPSSLSocketFactory());
}catch (IOException e){
e.printStackTrace();
}
Isn't that enough? What am i missing?
Thanks,
