J9 wlan connection handling - help needed

I wrote an application which is running on phone and communicates with a server. I can open sockets, and communicate with the server (read/write data on chanel), but after ferw minutes/hours(depend on trafic) the wlan connection between the client and server breakes. The problem is, that after an exception is thrown, I close th connection and try to open a new connection, but can't. It seems, that somewhere in the phone's operatin system the connection is not closed.
My question is , that is there anybody who meet this problem? The second question is that kind of workaround can be used to reconnect to the server?

hi,
have you found a solution? I have nearly the same problem now...
My application runs on windows mobile 6.1 with IBM j9. Connecting to the WLAN inclusive VPN works well on the device, browsing with internet explorer is no problem and if necessary the WLAN and VPN connections are established automatically if needed.
But when I try to invoke a webservice-request from within my java-application the connection isn't established. (Doing the webservice-request while a there is an existing connection everything works fine, e.g. when starting the application right after browsing in internet explorer).
Probably I have to tell the connection manager on wm6 to connect - but how do I implement that?
For .Net I found the following:
- http://msdn.microsoft.com/en-us/library/bb840031.aspx
- http://msdn.microsoft.com/en-us/library/ms849587.aspx
Can anybody give me a hint, please?

Computer restarts when ipod is connected urgent help needed

alright this is weird, I've had my ipod for ages and suddenly I go to plug it in and the computer slows down really really really slow and eventually just turns it self off, restarts and then sits in a black screen. if I leave the ipod plugged into the computer and restart it again it just goes straight back to the black screen, but both my ipod and computer work fine when there not connected. i have the latest version of itunes which seemed to help the first time i tried it actually started to update the ipod but then guess what the computer has another heart attack. urgent help needed please!!!

if I leave the ipod plugged into the computer and restart it again it just goes straight back to the black screen
Given this, I'd put it down to a flaky power supply in the computer. Might want to try using another computer or replacing the PSU.

WLAN Controller configuration help needed

Hi,
I need to configure AP with WLAN controller for guest access. we have 2 vlans. vlan 1 - guess vlan (internet only access) and vlan 2 - all access.
while configuring wlan controller. which vlan should i configure as native vlan? I have radius server which would check health of the user and would direct wlan controller to put in user in vlan 1 or 2 depending on its credentials.
please advise how to implement it. what would be initial steps.

Hi,
I have couple of doubts before going further for solution to implement ?
What model of wlan controller & AP , you are using ?
to configure the Controller , initially you need to configure the interface ( which are virtual ) .
You need to connect controller to your existing LAN set-up may be one of the port of your core switch ............
below are the interface which you need to configure in controller .......
1) Management interface with IP ( which will be used to access your controller from lan ... ) this is ip should be able to ping from the network.
2) AP manager IP ( this is again depend on model ) if it is 5500 , this is not required ..
3) Virtual IP : this is should the IP address which is not at all there in your lan eq.1.1.1.1
4) dynamic interface with IP : this is the interface which will map your vlan to WLAN
once you create the mentioned interfaces , you need to create the wlan and map the above dynamic interface with respective wlan.if required you can configure the DHCP pool as well in controller for Wlan.
let me know , whether this information helped you ........................

Dreamweaver Connections Folder Help Needed

I am working on Mac OS 10.4, Dreamweaver 8, PHP 4.1+ and
MySQL. I can get my database connection to work if I have it
directly in the PHP code but if I try to do it using the
Dreamweaver interface - the connection doesn't work. My testing
server and remote server all test ok on the connections. I believe
the problem is where the Connections folder is located but it
appears Dreamweaver only accepts it at the top level and the way my
hosting company configures their domains, it doesn't see the
connections folder and it doesn't work. I need to get it to work as
I want to use the Dreamweaver interface. I've searched every help
forum and tried many suggestions with no luck - anybody run into
the same problem?
Thanks!

Thank you for writing. I do need your help, and here's the
scenario. I work for a company that deals with business credit. In
the previous post at
http://www.businesscreditbuilder.com
there is a login. Once logged in, there is a home page for the
members. That first page I need to change as soon as possible for
over 40,000 members. All the members will see the same home page
inside the members area. You're welcome to login as "makaiman",
password is "1143mak" to see the first page that comes inside the
members area I need to change just a little. PHP is installed on a
remote server running on Windows. I need help or guidance on this
immediately but I have to sleep right now as it is 1130pm pacific
and need to have this done by sometime tomorrow morning. I
appreciate all of your help so very much... any advice would be so
much appreciated...

Connection Pooling Help Needed

Greetings.
I am trying to get a database connection in Websphere 5.0 (running on Redhat Adv. Server) and my connection times are very, very slow. Below is the code to get the connection:
Properties parms = new Properties();
parms.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"com.ibm.websphere.naming.WsnInitialContextFactory");
// Create the Initial Naming Context
Context ctx = new InitialContext(parms);
DataSource ds = (DataSource) ctx.lookup("jdbc/customer");
Connection con = ds.getConnection();
Here is the setup for the database connection within the Websphere Admin Console to an Oracle 8i database:
Implementation: oracle.jdbc.pool.ConnectionPoolDataSource
JNDI Name: jdbc/customer
Statement Cache Size: 10
Data source helper class name: com.ibm.websphere.rsadapter.OracleDataStoreHelper
Connection Timeout: 1800
Maximum Connections: 30
Minimum Connections: 10
Reap Time: 180
Unused Timeout: 1800
Aged Timeout: 0
Purge Policy: Entire Pool
We CAN connect to the database. We CAN run SQL statements and stored procedures just fine. Everything with the database is working correctly. ok, so here is the problem... The statement: Connection con = ds.getConnection(); Takes a long time. 3+ seconds. Every time. No Matter what the load is. We need to get this time down significantly. It's killing our web services.
Using JMeter, We have tested it using a single thread and up to 50 concurrent threads and it all runs the same. 3+ seconds. We actually changed the code to create a database connection just using JDBC with no JNDI lookup and it runs at the same speed. It is almost as if the connection pool is not working correctly.
So then we looked to see if we were ever getting the same connection twice, but when we printed out the object references, it looks like the connection is a brand new connection EVERY time because the object references are different. Please see the partial log file I have included below.
Right now, our theory is that the connection pool is just getting us a new connection every time without reusing existing connections. We have played with all the settings on minimum connections, maximum connections, and everything else and nothing seems to help.
Thank you to anyone that might be able to help us.

The problem might be the version of Driver Class you use... If you use Oracle 9x, u need to have new version of classes12.jar/zip. Do check it out.

Event Handling Help needed please.

Hi,
I am writing a program to simulate a supermarket checkout. I have done the GUI and now i am trying to do the event handling. I have come up against a problem.
I have a JCombobox called prodList and i have added an string array to it called prods . I have also created 2 more arrays with numbers in them.
I want to write the code for if an item is selected from the combo box that the name from the array is shown in a textfield tf1, and also the price and stock no which correspond to the seclected item (both initialised in the other arrays) are also added to the textfield tf1.
I have started writng the code but i am really stuck. Could someone please help me with this please. The code i have done so far is as follows(just the event handling code shown)
          public void ItemStateChange(ItemEvent ie){
          if(ie.getItemSelected()== prodList)
               changeOutput();
          public void changeOutput()
               if(ItemSelected ==0)
                    tf1.setText("You have selected" +a +b +c);
     }

Do you say this because i missed the d of ItemStateChanged ?
I have amended that but still i am getting the same errors class or enum expected. 4 of them relating to the itemStateChanged method.
i will post my whole code if it helps

Wi-Fi Connections issues: HELP NEEDED!

I've been running my iPhone mostly on the EDGE network the past few weeks. Some hair might have gone grey while I was waiting for it to laod, but it loaded after sometime.
Anyways, I have a linksys wireless router and everytime I try and use my Wi-Fi with the iPhone it says "Safari can't open the page because it could not connect to the server."
Does anyone have a solution for me to change settings through network settings, or anything eles that might be quick and easy?

Here is a quick check list you can take a look at and try. As well as a couple questions. It sounds like possible interference of some kind.
1. Has Firmware on the router been updated?
2. Have you updated iPhone Software to 1.0.1?
3. Have you done a restore on the iPhone and tested the network again?
4. You may wish to inquire to your router provider about changing the channel on your router, To see if it is stopping the iPhone from grabbing a stable connection.
Test your iPhone on another Wireless Network, If other Wireless Networks work, Then it could just be a compatibility issue with your router, But please inquire to your Router Provider about how your wireless device will not hold the information of the Router IP and other information, They may be able to change a setting in the router to help stabilize the connection.
Apple has also released a new router, The Airport Extreme 802.11n

Thank you

IPod not connecting! HELP NEEDED BADLY!

I have 2G iPod nano and I also have the newest iTunes downloaded (7.0.2). However, iTunes cannot find the iPod, or the iPod is not showing up in iTunes where it should (under the device section).
A message does come up, it is this:
An iPod has been detected, but the iPod software is not installed. Please install the iPod software from the CD that came with your iPod or download the iPod software updater from www.apple.com/ipod/download
I have done this and all it does is bring me to a place where I can download iTunes, which I already have.

Also, I do not have a CD.

SQL Server Database Connectivity with Visual Studio 2012 - Help Needed

Hello,
I am having Visual Studio 2012 and SQL Developer 4.0 installed on my system with Windows 8 - 64bit
I want to shift a VS project with an SQL database connectivity to another new Laptop (above mentioned) ...
I have the project opened in VS without bieng connected to the database..
I have a backup file of the database (which needs to be restored to a new created database on SQL Developer)
The problem:
I am unable to create a server connection in SQL Developer which will allow me to create a new database followed by the recovery from backup file.
I am getting the following error message when I try to create a connection:
Status: Faliure - IO error: The network adapter could not establish a connection
Please help me in setting up a server connection and adding a new sql database

The error message seemed unfamiliar to me and since I had never heard of SQL Developer before, I went to Google. Google might be pulling my legs, but it appears that SQL Developer is related to Oracle. This forum is devoted to SQL Server, so you are in the
wrong place.
Try finding a forum for SQL Developer.

Creative Cloud Connection Help Needs Mac Support

I'm very happy to see that the Creative Cloud Connection preview is now available.
I was VERY disappointed to see that the Help file only covers Windows computers. Please update it to support Macintoshes as well!

The "Creative Cloud Help / Getting started with the Creative Cloud Connection" page does have a section on MacOS: http://helpx.adobe.com/creative-cloud/kb/desktop-sync-getting-started.html
Is there a specific problem you're having with Creative Cloud Connection that you need help with?

Help needed in Connecting to SAP From Eclipse

Hi All,
Currently, we have a requirement where we need to retrieve data from SAP System and need to upload the same in a Third Party Application (Java based system).
We are able to create an account in Java Application using Eclipse IDE by hard coding the Account details. We are stuck up in establishing the SAP connection and retrieving the details and then creating the extracted account details in Java application from Eclipse.
Any pointers on this will be of great help.
Regards,
Eureka

Hi Eureka,
Please refrain from creating cross-posts in parallel forums, moreover this question is JCo-related and is not directly connected with Java EE 5. The Help needed in Connecting to SAP From Eclipse in the Java Programming forum would be enough. Please continue the discussion there.

Vladimir

Help needed to connect dual monitors.

Hi everyone. Here's my problem, I bought two Samsung SyncMaster 913v LCD TFT Displays.
Both of these displays (since they aren't the digital LCD) connect the same way my old Sony Trinitron MultiscanG400 display connected, which I believe is the VGA connection or SVGA or whatever... I'm not smart enough to look into the difference.
Anyway, I have the right Graphics/Video card to run dual monitors. I'm using the GeForce 2 TwinView and it has the required 64mb VRam.
My problem is that there is only one port on the back for monitors. I believe the connection type next to it is an old pre-usb printer/scanner type of connector, LPT1 or whatever those are called.
So do I need an adapter/connector to hook up both of my monitors to use it as a dual display? If not, what do I need to do?
Thanks.

Hi,
To clarify the last post by PB PM. Your present card meets those requirements.
The GF2 Twinview card is sufficient. It has two outlets, one is VGA the other is ADC (Apple Display Connector). You will need a ADC to VGA Adapter, they cost @ $25-30. Hook one monitor to the existing VGA outlet, the other to the adapter on the ADC outlet.
One example is here: http://eshop.macsales.com/item/AddLogix/MCAADCVGA/
You can google for other prices.
After the monitors are connected you may need to go to Displays Pref's and set it for dual monitors in Mirror or Span modes.

Dave
