One weblogic instance listening to multiple ports

I'd like to run weblogic with its http subsysten listen to port 80.
Any other service should listen to port 7001.
Is it really impossible to let weblogic do this?
Are there any plans to implement such a feature?
Which alternatives do exist?
TIA
klaus

No, it is impossible.
Alternatives: use IIS/Apache/NES to listen to port 90, and use weblogic
plugin to proxy request to WLAS (7001).
Still, you can use one WLAS listent to port 80, and use HttpClusterServlet
to proxy requests to another WLAS (7001)

Question: one weblogic server listening on several port

can i start one weblogic server that listening on several port, one for
different application?
for example,
7001 for general user, and
7005 for admistrators and ask for two way authentification?
can i do this? or do i have to start two weblogic instance? does that
violate it's license for one computer and one ip address?
thank u.

Ummm.. how would this help security? If I want to bypass authentication, I just go to the unprotected port.
I don't think you can listen to different ports in the same instance
. You can listen to different IP addresses in the same instance.
WL is licensed by CPU so this would not cost any more to license.

Multiple listen ports for one weblogic instance

Can anybody confirm that you can have only one listen port defined for a single
weblogic instance (i.e. one instance cannot be listening to multiple ports at
the same time)?
Thanks

you can have multiple ip's assigned to the same box
and bind each WLS instance to a unique which will listen
on the same port.

Can imapd listen on multiple ports?

For historical reasons, we've got some multiplexors that expect to make the back-end imap connecto to port 993, and some others that want to talk to 994. Is it possible to configure imapd to listen on multiple ports?
Thanks!

I just realized this would be doable if the MMP would do STARTTLS to the back-end (since then I could enable STARTTLS on the default port and keep SSL on connect on the other port).
If only.....

Listen on multiple ports for smtp?

Traditionally, we've provided setup smtp to listen on an additional port to 25 for travellers who find themselves on an ISP which blocks that port. We used a line in master.cf like:
<newportnumber> inet n - y - - smtpdproxywrite unix - - n - 1 proxymap
This seems to make snow leopard's postfix unhappy. It also doesn't work. I'd be grateful if anybody could tell me:
* what is or where to look for info on setting up postfix to do multiple ports? I've tried Apple docs and found nothing and only old-style in postfix docs -- though I could be missing something obvious as always.
* is this the modern and preferred way to get around the blocked port 25 problem or is it better to do some fancy-schmancy port redirection eg at the firewall to map multiple ports on to port 25 for postfix?
thanks and allbests,

In the past I've used the following with great success. Add the following line to /etc/postfix/master.cf file:
2525 inet n - n - - smtpd
Stop and start the mail service. Then test with telnet to ensure that the port is responding. Sadly, this still appears to be the best way, sans the use of a VPN, to get around ISP blocking.
Obviously port 25 needs to be open to receive mail. But instead of opening additional port in the firewall, you could drive all users to VPN.
I just tested the above line in 10.6.1 and it is responding.
Hope this helps

Listening to multiple ports(socets) for data?

I know that this topic has been covered before, but is either simplistic questions or overly complex things (that I don't understand... yet)
Here is my issue: I have data coming from two ports (TCP/IP) an array of 210 bytes and I'm not sure which port will be activated first. The data is asyncronus. So basically I want to figure out how to listen to the ports. I have this code...
import java.io.*;
import java.util.*;
import java.net.*;
public class SocketListener{
    public static void main(String[] argv){
        ServerSocket mySocket = null;
        ServerSocket mySocket2 = null;
        try {
            mySocket=new ServerSocket(12000);
            mySocket2= new ServerSocket (13000);
        catch (IOException e){
            System.err.println("error");
            System.exit(-1);
        try {
            Socket client = mySocket.accept();
            System.out.println("The server has connected to 12000\n");
            // do what I need it to do a.k.a. get data array
            client.close();
        catch(IOException e){
            System.err.println("error");
            System.exit(-1);
        try {
            Socket client2 = mySocket2.accept();
            System.out.println("The server has connected to 13000\n");
            // do what I need it to do a.k.a. get data array
            client2.close();
        catch (IOException e){
            System.err.println("error");
            System.exit(-1);
}I'm not sure if it works or not... but thats what I got. Is this the best way to go about this or is there something else that I should look up in documentation / look for examples / someone might have a link to something.
Thanks a lot!!!!

There are two issues at hand here, one being networking and the second being threading. Threading is an extensive subject and I don't want to shortchange you here, so you may want to read this tutorial if you are not familiar with Java threading concepts: http://java.sun.com/docs/books/tutorial/essential/concurrency/index.html
That being said, if you want to concurrently listen to the sockets, you will need a thread for each socket you are listening. Otherwise you can use Java NIO, but unless you are going to be listening to many sockets at once, this complication is not necessary since the learning curve of Java NIO can be quite steep.
You might want to start out creating a new class that will handle the task of listening to a socket and retrieving the data in its own thread. You can do this by either extending the Thread class or implementing the Runnable interface. From your main class, you can then spawn as many of those objects as you need. The trick to this approach is knowing when the data has been read from the socket and stored in the object. For only two objects this is simple as you can have a hasData() method on your worker objects and then just put a loop in your main class checking to see if the condition has been met on the objects.
Here's some code fragments as an example...
public class SocketReader extends Thread ...
ServerSocket ss = null;
boolean hasData = false;
SocketReader(int port) {
ss = new ServerSocket(port);
public void run() {
ss.accept();
// do your stuff
hasData =true;
public boolean hasData() {
return hasData;
main() {
SocketReader sr1 = new SocketReader(12000);
SocketReader sr2 = new SocketReader(12000);
sr1.start();
sr2.start();
// keep looping until we have data in both
while (!sr1.hasData() && !sr2.hasData()) {
try {
Thread.sleep(100);
} catch (InterrruptedException ie) {/ do something}
} // end main
Keep in mind that this is a very simplistic example to demonstrate the concepts and would not be a good design for pretty much any other case.

Netbeans 6.1 SMS NON-Brute force ability listen to multiple ports

First of all, my appologies for being a nubie coming from Mobile6. The company I slave at is migrating from MS Mobile to j2me!!! I am porting a code segment that listens to all incoming/outgoing SMS text messages and logs the messages into another java contact applet for our sales department. Our company policy(I cannot change) allows the sales department to use any/multiple SMS packages and install onto the device.
Based on my understanding of the (MessageConnection)Connector.open("sms://" foo); I must include a port address to listen in on. Is there a NON-brute forced methodogy to poll "active" ports the device is using to send/recieve SMS text message?

db,
I was reading a blog by Bill Day [http://weblogs.java.net/blog/billday/archive/2004/02/midp_push_using.html]
regarding MIDP Push; A paragraph jumped at me, it was "...
Whichever network(s) you're application will be using, you need to find out what protocols they allow inbound to handsets. At the least, most GSM carriers will allow SMS (since they use SMS for short text messaging). Assuming your network does support SMS, from the server part of your application you would need to generate an SMS message directed to the port you bound your MIDlet to in its static or dynamic push registry settings. Assuming the network passes the SMS as expected, your MIDlet should be awakened when the SMS arrives in the handset..."
Either I'm not understanding your reponse, the info in this blog is incorrect or I must include a port address as part of the open method of the Connector. Still confused.

SocketServer Listen on Multiple Ports

What is the optimal way to have a SocketServer listen on more than one IP/port combination? I'm looking for various ways of doing this including a quick and easy way and the best-practices way.
Thanks.

There is no way to 'have a SocketServer listen on more than one IP/port combination'. A SocketServer can only listen at one port. You need multiple SocketServer objects, and you should use multiple threads executing accept loops.

Different weblogic instances listening to a topic

          Hi,
          I have a scenario like this---.
          I have 2 weblogic servers running on two different m/c s .They are NOT in a cluster.They
          have their own JMS Servers running.There are some queues and one topic on each
          machine.There is a router which routes incoming messages to these servers and
          responses back.Each wl server has the same application running(The application
          that processes the messages) and is totally unware of the existense of the other
          server.
          I want that for some particular message delivered to a topic on one m/c the
          other m/c should also receive that particular message.
          e.g. a message that certain system configuration parameters are updated and all
          servers should synchronize their cached system parameters with the database.
          Is it possible to meet this requirement either by configuration or programatically.The
          application has MDBs listening to the messages.
          I am using WL server 6.1
          Thanx ,
          sunil


You can do this yourself by writing a forwarder that opens up connections to
          both servers receiving on one and forwarding to the other. You can also
          use the messaging bridge. However, if A is forwarding to B and B is
          forwarding to A it is cyclic. You need to discriminate the forwarded
          messages so your forwarder does not forward messages back to the original
          server.
          Of course you could upgrade to 7.0, use a cluster and a distributed topic.
          All the forwarding is taken care of, you don't have to worry about cycles,
          and the forwarded messages maintain their original message ids.

NSAPI - directing to multiple weblogic instances

Hi,
I am trying to redirect 2 different URLs (www.test.com/server1 and www.test.com/server2)
to distinct weblogic instances which run on ports 7001 and 8001. The NSAPI instructions
say to do the following in the obj.conf file -- see below. This works great if
I open a new browser window for each one. However, the problem occurs in a single
browser instance when switching between the 2 URLs. Both URL requests will only
be directed to one of the WebLogic instances -- the other WL instance is ignored
no matter what URL you enter.
Any ideas????
# Here we configure the NSAPI module to pass requests for
# "/weblogic" to a WebLogic Server listening at port 7001 on
# the host myweblogic.server.com.
<Object name="weblogic" ppath="*/weblogic/*">
Service fn=wl_proxy WebLogicHost=myweblogic.server.com\
WebLogicPort=7001 PathTrim="/weblogic"
</Object>
# Here we configure the plug-in so that requests that
# match "/servletimages/" is handled by the
# plug-in/WebLogic.
<Object name="si" ppath="*/servletimages/*">
Service fn=wl_proxy WebLogicHost=192.192.1.4 WebLogicPort=7001
</Object>

I am not sure I understand what you want to do.. From your example, what you
are doing is directing anything that has "weblogic" in the URL to a single
weblogic instance. In your case: myweblogic.server.com.
You are also directing anything with "servletimages" in the URL to :
192.192.1.4.
Both these servers are listening on port 7001. There is no mention of 8001.
Let's say you want to have all requests that have "server1" in the URL go to
one weblogic instance and all that have "server2" in the url goto the other
weblogic instance(port 8001), then you need to configure two object tags.
One that has a ppath="*/server1/*" and that will point to weblogic instance
1(port 7001) and another weblogic object that has a ppath="*/server2/*" and
points to weblogic instance 2(port 8001).
Hope this helps.

Eric

Listening multiple ports

is there anyway a serversocket can listen to multiple ports?like the the serversocket can listen ports between 1 to 1024?thanks!

no methods that i know of. except to create an array of serversockets but pass the handling of sockets to a centralized location.

Restricting weblogic's listen address

Hi,
I have a machine that has 3 IPs and I want weblogic to listen only to 2 of them.
Is there a way to do it?
WLS 10.3.0
Thanks

A single WebLogic server can support multiple NICs, and can listen on multiple ports. In addition to the "default network channel", you can configure any number of "custom channels".

How Can I Use Multiple Weblogic Instances in a Single OS

Hello Everyone,
Actually I have to install Some different applications. Few of them need weblogic 10.3.6 and others need 10.3.4. The OS am using is Oracle Enterprise Linux 5.
Now I am able to install 2 separate(One of 10.3.4 and 10.3.6) instances with two different users,In two different directories.
I have installed the weblogic 10.3.6 version with a user webadmin and installed node manager with port 5556. This is working fine.
The main problem here is :
In the second instance (10.3.4 ) installed with a a different user and gave the port number to NodeManager as 1600 and its not getting started. Its throwing error and also after some errors in the terminal am able to see that its reverting to port number 5556 only.
What might be the issue?
I have to install 2 different versions of weblogic in a single Server. But am failing with NodeManager. What Can I do to have multiple weblogic instances with multiple versions in a single server ?
Can anyone suggest a resolution for this please ?
Thanks in advance.

About opening multiple files at once (in one program instance)

While developing an Image Viewer application i realized i had to give it some functionality for when a user selects multiple images in a directory and presses enter to open them with my app.
Everything is going well except for one tiny detail:
The Windows OS believes i am trying to open several instances of my Image Viewer, it even alerts me that "Choosing to 'Open' 26 items at once may take a long time and cause your computer to respond slowly."
It then hangs for a few seconds before opening my app. And i am talking about only 26 items. If i were to open more, the time it hangs is proportional and for that time the cpu usage is as its maximum (in this case a quad core).
So, do you know about a solution to this? Or at least a workaround?
Ideally, Windows would end up knowing i'm trying to open several files in only one program instance.
ps: i already tried deactivating the code that loads the Images, even with the InvokeEvent Listener doing nothing, Windows takes a lot of time trying to open 26 program instances.

it should work the way she's doing it, unless something is broken in CC
try these other two options
1. select all files and press "Enter", they should all open
2. select all files and press the button "Open" in explorer Toolbar

Issue listeneing queue from Weblogic Cluster server with multiple managed server

Haveing issue listeneing queue from Weblogic Cluster server with multiple managed server.
Weblogic Cluster structure is like
Weblogic Cluster01
--ManagedServer01(http://server01.myhost.com:7001)
--ManagedServer02(http://server02.myhost.com:7001)
JMS Servers
JMSserver01 targeting: ManagedServer01
JMSserver02 targeting: ManagedServer02
JMSmodule
ConnectionFactory01 targeting:JMSserver01,JMSserver02
UDQueue01 targeting:JMSserver01,JMSserver02
Uniform Distributed Queue in Monitoring tab showing like this
mysystemmodule!JMSserver01@UDQueue01
mysystemmodule!JMSserver02@UDQueue01
So when I am sending message to any Host(by specifying the provider URL) its distributing equally on both server like
mysystemmodule!JMSserver01@UDQueue01 10
mysystemmodule!JMSserver02@UDQueue01 10
But when try to listen message from these queue, it is listening from one server, for which URL given to connect.
mysystemmodule!JMSserver01@UDQueue01 0
mysystemmodule!JMSserver02@UDQueue01 10
untill I connect to other server by giveing its URL, will not able to access other message left on the queue.
Solutions that tried
1) we have tried give both server URL coma sparated in provider URL
we need to configur same scenario for 5 managed server with 3 listener on other servers.
Do any one have solution for this.

You need to have:
1. Consumers connected to each UDQ member
OR
2. If no consumers in some of the members is expected, you can configure Forward Delay (specify the amount of time, in seconds, that a queue member with messages, but with no consumers, will wait before forwarding its messages to other queue members that do have consumers):
http://docs.oracle.com/cd/E12839_01/apirefs.1111/e13952/taskhelp/jms_modules/distributed_queues/ConfigureUDQGeneral.html
For example you can set it to 10 (10s)
