Hi All, I have written an Client/Server application. When my server is trying to send a big chink of data, i am getting the following exception javax.net.ssl.SSLException: SSLEngine error during encrypt: BUFFER_OVERFLOW src: java.nio.HeapByteBuffer[pos=16384 lim=16418 cap=16418]outNetBuffer: java.nio.HeapByteBuffer[pos=16421 lim=32836 cap=32836] at org.apache.mina.filter.ssl.SslHandler.encrypt(SslHandler.java:380) at org.apache.mina.filter.ssl.SslFilter.filterWrite(SslFilter.java:506) at org.apache.mina.common.DefaultIoFilterChain.callPreviousFilterWrite(DefaultIoFilterChain.java:421) at org.apache.mina.common.DefaultIoFilterChain.access$1400(DefaultIoFilterChain.java:38) at org.apache.mina.common.DefaultIoFilterChain$EntryImpl$1.filterWrite(DefaultIoFilterChain.java:745) at org.apache.mina.filter.codec.ProtocolCodecFilter$ProtocolEncoderOutputImpl.flush(ProtocolCodecFilter.java:384) at org.apache.mina.filter.codec.ProtocolCodecFilter.filterWrite(ProtocolCodecFilter.java:210) at org.apache.mina.common.DefaultIoFilterChain.callPreviousFilterWrite(DefaultIoFilterChain.java:421) at org.apache.mina.common.DefaultIoFilterChain.access$1400(DefaultIoFilterChain.java:38) at org.apache.mina.common.DefaultIoFilterChain$EntryImpl$1.filterWrite(DefaultIoFilterChain.java:745) at org.apache.mina.common.DefaultIoFilterChain$TailFilter.filterWrite(DefaultIoFilterChain.java:671) at org.apache.mina.common.DefaultIoFilterChain.callPreviousFilterWrite(DefaultIoFilterChain.java:421) at org.apache.mina.common.DefaultIoFilterChain.fireFilterWrite(DefaultIoFilterChain.java:415) at org.apache.mina.common.AbstractIoSession.write(AbstractIoSession.java:241) at org.apache.mina.common.AbstractIoSession.write(AbstractIoSession.java:200) I get this problem in my office network ( Tested on 3 different machines) but i am not able to reproduce it in my home network ( tried on 2 different machines). is it related to https://issues.apache.org/jira/browse/DIRMINA-471 ?

Problem with dispose(); Access denied Exception.

On calling dispose my application throws an exception and the application hangs. At the same time the CPU usage of the client goes to 100%.

Re: Problem with dispose(); Access denied Exception.
Hi Trustin, I am running a desktop application. This application is built on top of the netbeans platform and the exception is on calling the close() method on the IOSession object. The netbeans platform does implement some kind of security manager. I would like to mention that the application was working fine with the 1.x version. Is ther any change in the permissions required? But the application still hangs and the CPU usage goes to 100% as soon as I call dispose() on the connector.

How to gracefully shutdown a connection from client
Hi,
I am writting a Client-Server application with mina. I am having problem in
gracefully shutting down the client. the way i am trying to do is:
- The client sends a logout request to the server.
- The server does the clean up and closes the connection.
- The client is waiting for the connection to be closed by the server.
- As soon as the connection is closed the client does the cleanup and exit.
The first two steps are fine. But the client is not recieving close
notification, due to this the client is hanging.
The code is as under:
On server side when I recieve LOGOUT:
session.close();
On Client Side:
GenericRequest req = new
GenericRequest(Constants.REQ_LOGOUT, null);
WriteFuture future = session.write(req);
future.awaitUninterruptibly();
conHandler.shutdown();
pinger.shutDown();
System.out.println("Waiting to close::");
this.session.getCloseFuture().awaitUninterruptibly();
System.out.println("Closed ");
The client is hanging on
this.session.getCloseFuture().awaitUninterruptibly();
Please let me know what is the right way to gracefully shut down a client
application.
Thanx,
Saurabh

Re: How to gracefully shutdown a connection from client
When i try to use close at client side then i get a
java.security.AccessControlException: access denied
(java.lang.RuntimePermission modifyThread) due to the Security manager
implementation of my application. Does close operation require any specific
permissions?
Also I have gone through the examples and i think this is the same mechanism
used in the examples. (May be I have missed something [:(] ) I followed the
chat example.
