Accessing the EWS

Each networked printer has a very useful utility which allows the user to monitor, maintain, and alter the performance of the machine. This utility is called the Embedded Web Server or EWS for short. Accessing the EWS is easy, but does require that your printer have an IP address.
Simply open up a browser on a device on the network (computer, tablet, phone, etc) and enter the IP address into the browser's address bar. Press enter and it will navigate you there.
Once you are here you will be presented a variety of options that varyies depending on your printer model and capabilities.

Not sure how you setup your email addresses, I just ran into the same issue. We had the address that I was assigning to UM as hidden from Exchange address lists. Once I unchecked the "Hide from Address List" box I was able to re-provision
the UM properties.

Where do I find the EWS for a Photosmart 7520?

I want to change the direct print password and the touchscreen says to change it in the EWS. Where is the ews?
This question was solved.
View Solution.

The EWS is the Embedded Web Server. This is the internal website created for the printer whenever it is connected to a network.
To access the EWS:
* Obtain the IP address of the printer from the front panel of the unit
* Open preferred web browsing program
* Type the IP address in the URL bar and press Enter to access the page
Let me know if you need more information.

How do I access the web utility with model cisco sf302-08p ?

Hi,i have a problem with the model Cisco SB SF302-08PP Switch , i connect a cable rj45 to my pc and configure the adapter local area connection (ip address:192.168.1.252), the LEDs blink green, and go to the address bar and get the IP by default, which according to the manual is 192.168.1.254 and the result is: page not found. Is there any way to change the web utility? How do I access the web utility?

restore the switch by holding more than 30 seconds and try accessing with ip 192.168.1.254. username and password is "cisco". before change your base ip to 192.168.1.2-253.try to ping and check the connectivity

Prevent multiple users accessing the same form

hi,
i am working in forms
i have a requirement like this
if more than one user are using the same form and try to access the same record then the second user should not be able to do transaction
he should be popped up with a msg saying that other user is working on it
can any one suggest how to do this in my form
thanks in advance
selvaraj s

That is pretty much exactly the way Forms works automatically.
Two users can use the same form, and can even display the same data record. One of the users can make changes to the record -- Forms locks the row upon the FIRST keystroke in the first field the user begins to change.
Once the row is locked, the second user is free to look at the record, and won't even know if another user has begun making changes. However, if second user tries to change even one field in the record, Forms pops up the message, "Could not reserve record (2 tries). Keep trying? Yes / No"
There are also protections so if the first user actually changes the row and commits, then the second user tries to make a change. Forms will automatically detect whether changes were made, and if so, will undo the change and issue the message, "FRM-40654: Record has been updated by another user. Re-query to see change."
The above automatic processing works very nicely. If it will not work for you, then what is it you need?

Multiple users accessing the same data in a global temp table

I have a global temp table (GTT) defined with 'on commit preserve rows'. This table is accessed via a web page using ASP.NET. The application was designed so that every one that accessed the web page could only see their data in the GTT.
We have just realized that the GTT doesn't appear to be empty as new web users use the application. I believe it has something to do with how ASP is connecting to the database. I only see one entry in the V$SESSION view even when multiple users are using the web page. I believe this single V$SESSION entry is causing only one GTT to be available at a time. Each user is inserting into / selecting out of the same GTT and their results are wrong.
I'm the back end Oracle developer at this place and I'm having difficulty translating this issue to the front end ASP team. When this web page is accessed, I need it to start a new session, not reuse an existing session. I want to keep the same connection, but just start a new session... Now I'm losing it.. Like I said, I'm the back end guy and all this web/connection/pooling front end stuff is magic to me.
The GTT isn't going to work unless we get new sessions. How do we do this?
Thanks!

Thanks!You may want to try changing your GTT to 'ON COMMIT DELETE ROWS' and have the .Net app use a transaction object.

How can I verify my iCloud account if I can not access the primary email account associated with my Apple ID?

The email address I had set for my Apple ID when I had originally signed up was through my college. I have been out of college now for a few years and the email account has been deleted. I was trying to set up iCloud on my iPad and iPhone but it says I need to access the account to verify through email. I have tried to change my Apple ID email to my current email address but it tells me I can not do this either because that email is set up as my rescue email. How can I change my primary email address for my Apple ID or get my iCloud verified in this situation I'm in?

Go to http://appleid.apple.com and click 'Manage your account'. You will be able to change the non-Apple email address you use as a login. You will then need to log out and in again on all your devices.

move the entire iTunes folder to <MacintoshHD>/users/shared. on each user account, launch iTunes while holding the option(⌥) key, click on choose library when prompted, and select the iTunes folder you moved to the share folder.
be aware only one iTunes at a time can access the library !

Access the Name and Value of a StationGlobals container programatically

Hello,
I am having some trouble trying to programmatically write the contents of a container into my HTML report header. The container contains a series of strings and numbers. These are saved into StaionGlobals.
Note that I am performing all of these operations in a statment step inside the sequence editor of TestStand
I used the following method to access the correct property, which sits inside a for loop. Now this seems to work fine as Locals.PropertyObj contains the element which I wish to access. In the following Locals.PropertyObj is an object. TestSetup is the name of my setup information container
Locals.PropertyObj = StationGlobals.GetNthSubProperty("TestSetup", StationGlobals.ForIterator, 0)
I can access the Name of the parameter simply by using the following code (where Locals.Name is a string):
Locals.Name = StationGlobals.GetNthSubPropertyName("TestSetup", StationGlobals.ForIterator, 0)
However when I try to access the actual value of the parameter I get an error or the wrong information. The following line gives me back the value "PropertyObject, IID = {8D87....}" which is not the value I am trying to get to.
Locals.Val = StationGlobals.GetNthSubProperty("TestSetup", StationGlobals.ForIterator, 0)
I must be doing something wrong, and have tried various methods to do this but cannot get my head around the problem. I tried to use the following also, but it resulted in an error:
Locals.PropertyObj.AsPropertyObject.GetFormattedValue((Locals.PropertyObj.AsPropertyObject).Name, 0, "", False, "")
Note that the following line works fine:
(Locals.PropertyObj.AsPropertyObject).Name
Also can you tell me why the lookup string needs to be defined in Locals.PropertyObj.AsPropertyObject.GetValueString(), is there a way to not require the lookup string as you are already have the correct property, and just the value is needed to be gotten.
One last thing, in Evaluate() how do I make it work with dots, for example the following line (another attempt to get the value) did not work due to the presence of the . character
Evaluate("StationGlobals.TestSetup." + (Locals.PropertyObj.AsPropertyObject).Name)
Many thanks in advance of your response,
Ben Lawler
ps. hope that I am not being stupid and missed something very obvious

Ben,
Just a few comments;
[Locals.PropertyObj = StationGlobals.GetNthSubProperty("TestSetup", StationGlobals.ForIterator, 0)]
This should give you a PropertyObject for the 1st subproperty of StationGlobals.TestSetup if StationGlobals.ForIterator = 0
[Locals.Name = StationGlobals.GetNthSubPropertyName("TestSetup", StationGlobals.ForIterator, 0)]
This should give you the name of the 1st subProperty of StationGlobals.TestSetup if StationGlobals.ForIterator = 0
[Locals.Val = StationGlobals.GetNthSubProperty("TestSetup", StationGlobals.ForIterator, 0)]
This is going to return the 1st subproperty of StationGlobals.TestSetup if StationGlobals.ForIterator = 0 as a PropertyObject reference
and Locals.Val should be an ActiveX Reference type which I am guessing it isn't.
[Locals.PropertyObj.AsPropertyObject.GetFormattedValue((Locals.PropertyObj.AsPropertyObject).Name, 0, "", False, "")]
I think this should be Locals.PropertyObj.GetFormattedValue("", 0, "", False, ""), you dont need to specify the lookup string because you have obtained a reference to the actual sub-PropertyObject.
and therefore
Locals.Val = Locals.PropertyObj.GetFormattedValue("", 0, "", False, "")
should give you the value of the 1st subproperty of StationGlobals.TestSetup if Locals.PropertyObj was obtained as above.
I will try to check out your sequencefile later when I have access to TestStand 4.x.

Not able to access the Oracle I/PM web client.

I have started the Administration server and the Oracle I/PM Managed Server. Now I'm trying to access the Oracle I/PM web client at this URL: http://hostname:16000/imaging. But when I hit this URL, the following error comes up:
Error 404--Not Found
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.

Hi Srinath,
I have checked that as well, it is showing the IPM_server in running mode.
Also it doesn't show any deployment failure in the command line. Here is what it shows:
<May 20, 2013 10:32:51 AM IST> <Notice> <WebLogicServer> <BEA-000332> <Started W

<May 20, 2013 10:32:52 AM IST> <Notice> <WebLogicServer> <BEA-000360> <Server st

I feel there is some issue as this log is suggesting:

I have just sought to update my lightroom and am now unable to access the develop function and get a note stating that I have reduced functionality what it this about and how do I get my product back

Hi there
I have version 5.7 and every time I opened it I was told that updates are available and to click on the icon to access these. Instead it just took me to the
adobe page with nowhere visible to update. I then sought to download lightroom cc and this is when I could not access the 'develop' section due to reduced
functionality It was apparent that my photos had been put in cc but no way to access them unless I wanted to subscribe.
I have since remedied the problem as my original lightroom 5.7 icon is still available on the desktop and have gone back to that. I do feel that this is a bit
of a rip off and an unnecessary waste of my time though.
Thank you for your prompt reply by the way.

Access the nodes data in a table view (generated by aet).

Hi all ,
I have created a table view in bp overview page.
so it has created new component /ztable/zbol entity .
Now how can i access the nodes of BP page..in the new component created?.

thanks vishal ,
but as per the thread,when we create table view using aet ,
Table view in EHP1 CRM 7.0
You dont need to worry about the component usage nor you need to create or handle anything like that for AET compoent for table extension. SAP has a special way to handle it in WD_USAGE_INITIALIZE of component controller for AET extension generated component so its nothing for us to do about it. Thanks to SAP
so still i need to redefine..or can directly access the nodes in do_prepare_output.?

Accessing the same stateful session bean from multiple clients in a clustered environment

I am trying to access the same stateful session bean from multiple
          clients. I also want this bean to have failover support so we want to
          deploy it in a cluster. The following description is how we have tried
          to solve this problem, but it does not seem to be working. Any
          insight would be greatly appreciated!
          I have set up a cluster of three servers. I deployed a stateful
          session bean with in memory replication across the cluster. A client
          obtains a reference to an instance of one of these beans to handle a
          request. Subsequent requests will have to use the same bean and could
          come from various clients. So after using the bean the first client
          stores the handle to the bean (actually the replica aware stub) to be
          used by other clients to be able to obtain the bean. When another
          client retrieves the handle gets the replica aware stub and makes a
          call to the bean the request seems to unpredictably go to any of the
          three servers rather than the primary server hosting that bean. If the
          call goes to the primary server everything seems to work fine the
          session data is available and it gets backed up on the secondary
          server. If it happens to go to the secondary server a bean that has
          the correct session data services the request but gives the error
          <Failed to update the secondary copy of a stateful session bean from
          home:ejb20-statefulSession-TraderHome>. Then any subsequent requests
          to the primary server will not reflect changes made on the secondary
          and vice versa. If the request happens to go to the third server that
          is not hosting an instance of that bean then the client receives an
          error that the bean was not available. From my understanding I thought
          the replica aware stub would know which server is the primary host for
          that bean and send the request there.
          Thanks in advance,
          Justin


          If 'allow-concurrent-call' does exactly what you need, then you don't have a problem,
          do you?
          Except of course if you switch ejb containers. Oh well.

Can not access the Instance Data of a Singleton class from MBean

I am working against the deadline and i am sweating now. From past few days i have been working on a problem and now its the time to shout out.
I have an application (let's call it "APP") and i have a "PerformanceStatistics" MBean written for APP. I also have a Singleton Data class (let's call it "SDATA") which provides some data for the MBean to access and calculate some application runtime stuff. Thus during the application startup and then in the application lifecysle, i will be adding data to the SDATA instance.So, this SDATA instance always has the data.
Now, the problem is that i am not able to access any of the data or data structures from the PerformanceStatistics MBean. if i check the data structures when i am adding the data, all the structures contains data. But when i call this singleton instance from the MBean, am kind of having the empty data.
Can anyone explain or have hints on what's happening ? Any help will be appreciated.
I tried all sorts of DATA class being final and all methods being synchronized, static, ect.,, just to make sure. But no luck till now.
Another unfortunate thing is that, i some times get different "ServicePerformanceData " instances (i.e. when i print the ServicePerformanceData.getInstance() they are different at different times). Not sure whats happening. I am running this application in WebLogic server and using the JConsole.
Please see the detailed problem at @ http://stackoverflow.com/questions/1151117/can-not-access-the-instance-data-of-a-singleton-class-from-mbean
I see related problems but no real solutions. Appreciate if anyone can throw in ideas.
