that?For MS Access? Why would you want to?
There is no server service for MS Access - you would have to create it yourself.
And there is a good reason that there isn't one. The only way to get to MS Access using ODBC is with a mapped drive on the client machine. And that means if the source of the database changes then every client machine must have the mapped drive changed. Now you could certainly do that in java (using JNI) but it certainly isn't a 'normal' part of a data source service.
Given the above I can't see that a data source service for MS Access is really going to be useful. But as I said you can't create it yourself.

DataSource Interface

Hi everybody,
I am new in jdbc3.0. I've read the jdbc3.0 specfisication and I found out the sun encourages uses of DataSource interface for obtaining connections.
I use SQL Server 2000 as database.
I have some questions regarding this:
1. Does Microsoft develop any class that implements this interface?
2. How difficult is to implement a Datasource for connecting to SQLServer database? Any reference is welcomed.
Thnks.

Sure, you can search "MicroSoft JDBC driver" in microsoft website. Actually all database vendors (like DB2, Sybase, Oracle) have their own JDBC driver implementations. Third-party vendor, such as DataDirect, also provide JDBC drivers for these databases.
Regarding to the second questions, the effort will depend on how much you want to develope. If you only want to implement JDBC extension (javax.sql.*) on top of java.sql.* implementation (JDBC base drivers), that won't be too difficult. However, if you want to develope a driver which implements both java.sql.* and javax.sql.*, you are founding a company like DataDirect. :)

How to create a login interface in labview PDA module?

How to create a login interface in labview PDA module? So that it checks with a list of usernames and passwords and allow to go to another VI?
Anu

Anu,
I've attached a really short example that does something like what you're talking about. It just compares the user's username and password a pre-determined username and password and then "logs the user in" based on that comparison. Like Greycat said, you probably want to store this username and password info in some sort of file on the PDA that's in an encrypted format for both security and flexibility of your application.
I hope this helps,

How to handle multiple datasources in a web application?

I have a J2EE Web application with Servlets and Java ServerPages. Beside this I have a in-house developed API for certain services built using Hibernate and Spring with POJO's and some EJB.
There are 8 databases which will be used by the web application. I have heard that multiple datasources with Spring is hard to design around. Considering that I have no choice not to use Spring or Hibernate as the API's are using it.
Anyone have a good design spesification for how to handle multiple datasources. The datasource(database) will be chosen by the user in the web application.

Let me get this straight. You have a web application that uses spring framework and hibernate to access the database. You want the user to be able to select the database that he wants to access using spring and hibernate.
Hopefully you are using the Spring Framework Hibernate DAO. I know you can have more that one spring application context. You can then trying to load a seperate spring application context for each database. Each application context would have it's own configuration files with the connection parameters for each datasource. You could still use JNDi entries in the web.xml for each datasource.
Then you would need a service locater so that when a user selected a datasource he would get the application context for that datasource which he would use for the rest of his session.
I think it is doable. It means a long load time. And you'll need to keep the application contexts as small as possible to conserve resources.

How to Add a Physical Interface After Installation in Solaris 10

How to Add a Physical Interface After Installation in Solaris 10
Hi Java Specialist,
I am trying to setup a network interface with the following steps on a new fresh Solaris 10 installation using the instruction titled How to Add a Physical Interface After Installation in Solaris 10 3/05 ONLY from http://docs.oracle.com/cd/E19253-01/816-4554/esxhb/index.html:
1. # ifconfig lo0 plumb up
2. # ifconfig lo0 10.56.8.101 netmask 255.255.240.0. This was the working Windows DHCP environment prior to installing Solaris
10 on top of it.
3. # Added saturn to /etc/hostname.lo0.
4. # Added 10.56.8.101 to /etc/inet/hosts
5. # Added 10.56.0.0 255.255.240.0 to /etc/inet/netmasks
6.# reboot
However, the following errors kept recurring:
svcs –xv …. unable to qualify my own domain name,
failed with exit status 69.
Any idea on what other steps have I missed? I was hoping to only do step 3 – 6 for the change to apply permanently.
Many thanks,
Jack

Hi Java Specialist,... in a Solaris forum?
1. # ifconfig lo0 plumb upThe loopback connection (your lo0)is NOT a physical interface. There are no hardware components for it. Nor can I think of any reason why it should ever be anything other than the default 127.0.0.1
Use your favorite Internet search site (such as Google, Bing, Yahoo) to learn more about it.
2. # ifconfig lo0 10.56.8.101 netmask 255.255.240.0. This was the working Windows DHCP environment ...I have no idea how a nonexistent software construct gets a DHCP address in a MS Operating System, unless you are confusing this with the "Microsoft Loopback Adapter" which is an utterly different concept. Again, go see what Google tells you.
 
 
 
... completely unrelated to configuring an IP...
unable to qualify my own domain nameAgain, search the Internet or even search these forums with that string of words.
Go back through your two most recent posts and read the responses again.
They seem to both be on the same topic as this new one -- configuring an IP on something.

When you've done all that, then come back and tell us what you are actually trying to do.

How to create a datasource for 0COSTCENTER to load data in csv file in BI

how to create a datasource for 0COSTCENTER to load data in csv file in BI 7.0 system
can you emil me the picture of the step about how to loaded individual values of the hierarchy using CSV file
thank you very much
my emil is <Removed>
allen

Step 1: Load Required Master Data for 0CostCenter in to BI system
Step 2: Enable Characteristics to support Hierarchy for this 0Cost Center and specify the External Characteristic(In the Lowest Node or Last Node) while creation of this Characteristic InfoObject
Step 3: On Last Node of Hierarchy Structure in the InfoObject, Right Click and then Create Hierarchy MANUALLY by Inserting the Master Data Value as BI dosent Support the Hierarchy load directly you need to do it manually....
Step 4: Mapping
Create Text Node thats the first node (Root Node)
Insert Characteristic Nodes
Insert the Last Node of the Hierarchy
Then you need to create a Open hub Destination for extracting data into the .csv file...
Step1 : Create the Open Hub Destination give the Master Data table name and enter all the fields required....and create the transformations for this Open Hub connecting to the External file or excel file source...then give the location on to your local disk or path of the server in the first tab and request for the data...It should work alright let me know if you need anything else...
Thanks,

How to change the Ethernet Interface name in Solaris 10

I have to install Oracle 10G RAC on three nodes with different ethernet cards, but the ethernet interface name must be the same which is the precondition for Oracle RAC installation.
So I want to know how can I change the ethernet name in Solaris.
For example, the ethernet name in the OS is "ce0", how can i change the interface name "ce0" to "e1000g0".
bash-3.00# dladm show-dev
ce0 link: unknown speed: 1000 Mbps duplex: full
ce1 link: unknown speed: 100 Mbps duplex: half
ce2 link: unknown speed: 100 Mbps duplex: half
ce3 link: unknown speed: 100 Mbps duplex: half
ce4 link: unknown speed: 100 Mbps duplex: half
ce5 link: unknown speed: 0 Mbps duplex: unknown
Thanks in advance.

You can't. The ce or e1000g refers to the driver as well as the adapter itself. The only exception I am aware of is: the ipge and e1000g which both refer to the Intel Pro 1000.I'm pretty sure I've renamed a driver in the past (and all references to it in name_to_major, path_to_inst, driver_aliases, and minor_perm) and had it function just fine after 'plumb'ing it up. However I just tested this by trying to turn a 'pcn' driver into a 'foobar' driver on a vmware box. It looks like everything works except some internal bits of the driver continue to create one file with 'pcn' in the name instead of 'foobar'. And since this is Solaris 10, the /devices filesystem is dynamic and read-only. I can't seem to force the change.
So while this may be possible with some drivers (and maybe only on older versions of the OS), it doesn't seem to be generally possible for all drivers on Solaris 10.

How to avoid long user interface response time in long measurements ?

Hi
I tried to find more information regarding techniques how to avoid long user interface response times in case of extremely long measurement times with an external instrument communicating over GPIB, so I post this hoping to get some hint or a link to a guideline. I guess this is quite normal problem.
Problem is that when I want to measure long time in order to get an average result from the instrument, I have to wait until the result is returned from the instrument. Obviously that makes the user interface response very slow in traditional technique.
My restriction is the old GPIB 488 instrument driver that I would not want to modify, but I have source code to it.
What would be the best way to improve the response time for user interface ? I have looked into the few things:
* multithreading
* callback in main program for GPIB events
* modifying instrument driver e.g. to support VISA and creating a VISA callback
regards,
Petri

Several ways to do this:
If you're getting several measurements, you could have the instrument generate an asynchronous interrupt (an "SRQ" in GPIB terms), then collect the data in response to the SRQ callback. While you're waiting for the SRQ's, you can have your main thread running the interface so responsive GUI. You don't have to spinlock on the GPIB read waiting for instrument data.
Or, as you mentioned, you could spawn a thread to manage the measurements, and use a timer in the main thread to periodically allow you to check the status of the measurement thread. Again, the main thread mostly just runs the user interface.
Either way, the idea is to keep the main thread freed up most of the time to run the GUI, and have it periodically check for completion of your measurement sequence. While you're waiting in the main thread, you may want to make sure the user can't inadvertently re-trigger another measurement sequence until the active one is complete.
If you do find yourself doing a dead wait, you'd want to break this up into a series of shorter waits, and in between each wait, do a ProcessSystemEvents from the main thread to keep the GUI active.
