In my weblogic server ehcache is deployed , I need to get ehcahe mbeans from this program through java programming, Through JMX i am not able to connect.how can i get those custom mbeans??
i tried to get mbeans through weblogic t3 protocol

CacheManager manager = CacheManager.newInstance();
Ehcache cache = manager.getEhcache("Some cache name here..."); //<-- PLEASE EDIT THE CACHE NAME...
I don't know if this is what you're asking for....
Once you've obtained your cache, you can use it, pretty much like a java Map.
You can follow the Ehcache documentation to see how to programmatically get the remote cache. Essentially, you will need to create a configuration (or configuration file) which the CacheManager can access.

We have an old client application that is deployed on JBoss 4.2.3 and written in JAVA EJB2. It has classes that depend on JBoss's security libraries, an Oracle DataSource and ANT as build method. Now there is a need of upgrading the application server because JBoss 4 no longer has life support and we are required to upgrade to Wildfly(Version 8.2 in our case). Naturally we are having a lot of problems during the process and working tirelessly just to go no further from where we are.
I just would like to get community's thoughts on this process. Is it worth the effort to upgrade JBoss or should one just re-write the client from scratch with a newer technology e.g Spring? What is the best practice in a situation like this?
By the way this client is not a big application, it is used by only 6 users.
As proposed by Michele Dorigatti, Here are some more details on the project:
I already spent an estimate of 15 m/d on the upgrade proces.
We are required to implement the solution in 3 weeks from now on.
The app itself isn't that large, it consists of 1 login screen and 1 main view. There are several functionalities which would make up to maybe 15-20 use cases.
The team for the project consists of 2 developers (One being me), who have another project on their hand.
The app functions mainly on Oracle stored procedures and works maybe on 5-10 DB tables.
Also here is an example code snippet from the app

is there any wrong in my code ?
May be i am very late to answer your question but still if anyone needs how to connect with SFTP using jsch library.
You can use below method
static Session session = null;
static Channel channel = null;
public Session sftpConnection(final String value, final String sftpUser, final String sftpHost, final int sftpPort,
final String sftpPass) {
System.out.println("preparing the host information for sftp.");
try {
JSch jsch = new JSch();
this.session = jsch.getSession(sftpUser, sftpHost, sftpPort);
if (value.equals("puttyServer")) {
this.session.setProxy(new ProxySOCKS5("proxy need to add", Integer.parseInt("portnumber need to add")));
}
this.session.setPassword(sftpPass);
java.util.Properties config = new java.util.Properties();
config.put("StrictHostKeyChecking", "no");
this.session.setConfig(config);
this.session.connect();
return this.session;
} catch (Exception ex) {
ex.printStackTrace();
sftpConnection(value, sftpUser, sftpHost, sftpPort, sftpPass);
}
return null;
}
You are starting an FTP server, but connecting to it using an SFTP client.
That cannot work. The FTP and SFTP are two completely different and incompatible protocols.
This could be the issue of whitelisting the servers.
Consider there are two servers named X and Y and You are trying to connect to Y from X using Jsch SFTP.
In that case, server X should be in white list of server Y.

**j=io.getByte();** //io.getByte() reads the key which is shared between two servers
if(j<0)break;
buf.buffer[i]=(byte)j; i++;
if(j==10)break;
}
if(j<0){
throw new JSchException("connection is closed by foreign host");
}
just tweak the sshd_config 'MaxStartups' count, for example 'MaxStartups 1000', and restart ssh
I have been trying to invoke an operation on ThreadMXBean in a remote jvm. The code snippet I used invoke the operation is below
bean = new ObjectName("java.lang:type=Threading");
memoryInfo = RemoteConnector.getRemote().getMBeanInfo(bean);
RemoteConnector.getRemote().getObjectInstance(bean);
MBeanOperationInfo [] mBeanAttributeInfos = memoryInfo.getOperations();
for(MBeanOperationInfo mBeanAttributeInfo : mBeanAttributeInfos){
System.out.println(mBeanAttributeInfo.getName());
}
long [] allThreadIds = (long [])RemoteConnector.getRemote().getAttribute(bean,"AllThreadIds");
Object [] params = new Object[2];
int maxDepth = 100;
params[0] = allThreadIds;
params[1] = maxDepth;
String [] opSigs = {allThreadIds.getClass().getName(),"I"};
RemoteConnector.getRemote().invoke(bean,"getThreadInfo",params,opSigs);
Note that getRemote() method returns a mbeanserverconnection
I can't invoke the method getThreadInfo() on stub. I am getting this message
2016-05-05 00:17:37 ERROR ThreadDumpCreator:67 - Operation getThreadInfo exists but not with this signature: ([J, I)
Please help me resolve this issue :)
Below is the method i used to connect remote mbeanserver
public class RemoteConnector {
private static MBeanServerConnection remote = null;
private static JMXConnector connector = null;
public static void defaultConnector(){
try {
JMXServiceURL target = new JMXServiceURL
("service:jmx:rmi://localhost:11111/jndi/rmi://localhost:9999/jmxrmi");
//for passing credentials for password
Map<String, String[]> env = new HashMap<String, String[]>();
String[] credentials = {"admin", "admin"};
env.put(JMXConnector.CREDENTIALS, credentials);
connector = JMXConnectorFactory.connect(target, env);
remote = connector.getMBeanServerConnection();
}catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
public static MBeanServerConnection getRemote() {
return remote;
}
public static void setRemote(MBeanServerConnection remote) {
RemoteConnector.remote = remote;
}
public static void closeConnection() throws IOException {
if(connector != null){
connector.close();
}
}
}
Apparently I should have used int.class.getName() as the method signature requires from invoke method
We have configured OID/OAM as our security providers in weblogic security.
On checking user attributes, only user id is visible.
How to get all attributes available in OID/OAM to available in Weblogic Security User and Groups?
Short Version: Use JMX as described here to get the configured OID-Authenticator-MBean. You can then use that MBean to get the necessary parameters to establish your own Connection to the OID and traverse the attributes. You might also want to read about Java Naming and Directory Operations here
Sample Implementation:
