Gerneral questions about express

Hi:
I am student who lives in a dorm. I have ethernet in my room but no wireless available. I would like to know if it will work to give my a small wireless network in my dorm room. Does anybody know any advantages I would have to go to Airport Extreme or should I just stay with express. Is there security so I can put a password on the network and I pretty sure a PC can join.
Thanks for all your help

Hello Tyler Parker. Welcome to the Apple Discussions!
I am student who lives in a dorm. I have ethernet in my room but no wireless available. I would like to know if it will work to give my a small wireless network in my dorm room.
Unless your school's IT staff does not allow for wireless networks, the AirPort Express Base Station (AX) can be configured to work with the existing Ethernet network to provide wireless coverage. This wouldn't be much different than using an Ethernet connection at a hotel.
Does anybody know any advantages I would have to go to Airport Extreme or should I just stay with express.
The only advantage of the AirPort Extreme is that it would offer additional Ethernet ports. If all of the devices in your dorm room will be wireless, then stick with the AX.
Is there security so I can put a password on the network and I pretty sure a PC can join.
Unless the PC is old, it should be able to connect with WPA Personal (or WPA-PSK in Windows terms). The AX supports, WEP, WPA Personal / WPA Enterprise, or WPA2 Personal / WPA2 Enterprise.

Question about expression language

Hello,
I have a question about expression language - is it possible to access one variable using abother EL as variable name? For example?
${applicationScope[${sessionScope.project.name}]}Or is there any other way of achieving that?
Thanks a lot for your help
Cheers,
Maciej
Edited by: swider on Oct 29, 2008 2:12 AM

I ran some other tests and I found out that following expression does not return value:
${applicationScope[sessionScope.project.aclId]}but this one is working
${applicationScope[sessionScope.aclId]}It is very strange. Project class ia simple JavaBean, has two members (Long and String).
Any ideas what can be wrong with that?
Cheers

Questions about Expression Filters

Hi.
I've read several times the excellent article "Filter Data Before you Get it" and am seriously considering as number one option for implementing an "Event and Notification Module" for an application. The flexibility and advantages addressed at the end of the article are good enough reason. However i have the following questions:
- Can I add or delete and attribute to an existing attribute set?. The idea would be to provide users with the ability to add or delete attributes of interest through the use of some metadata. If not, what would be the implications of recreating the attributtes, since there are several objects related to an attribute set(types, triggers, etc.).
- Can i evaluate expressions on a one by one basis?. The example showed always evaluate all expressions at the same time. My idea here, would be give the users the possibility of specifying the frequency of evaluating a particular expression, since all might not be equally important.
- Can i use the result of a pl/sql function and use it in an expression set. Again, sometimes things might be more complicated than evaluating columms of a table on a expression.
Thanks in advance .... Regards, Luis ...!

Luis,
Please find my responses below.
- Can I add or delete and attribute to an existing attribute set?. The idea would be to provide users with the ability to add or delete attributes of interest through the use of some metadata. If not, what would be the implications of recreating the attributes, since there are several objects related to an attribute set(types, triggers, etc.).At this time, an attribute set associated with an expression column cannot be edited (adding new attributes or deleting some attributes). The index and the trigger created to maintain the expression column are closely tied with the attribute set. So, you will have to drop the Expression Filter index and unassign the attribute set in order to recreate the attributes.
- Can i evaluate expressions on a one by one basis?. The example showed always evaluate all expressions at the same time. My idea here, would be give the users the possibility of specifying the frequency of evaluating a particular expression, since all might not be equally important.Yes, this can be done by specifying additional predicates in the query with EVALUATE operator. For example, the following query only evaluates the expression associated with a specific customer.
SELECT * FROM Customers
WHERE CustId = 1234 and
EVALUATE (Interest, :data) = 1
But, what is the logic behind "all might not be equally important" ? Often, rules are associated with a priority and the matching rules are ordered based on their priority. In this case, all the expressions are evaluated. But the application ignores the rules with low priority when there a matching rule with high priority.
- Can i use the result of a pl/sql function and use it in an expression set. Again, sometimes things might be more complicated than evaluating columns of a table on a expression.Yes, you can use user-defined functions in the stored expressions. See Example 10.3 in the Application Developer's Guide - Rules Manager and Expression Filter (10g Release 2) for a sample.
If you have 10g Release 2, you may also want to look at the Rules Manager feature. This feature allows declarative specification of complex Event-Condition-Action rules in the database and it is built on Expression Filter feature. With the Rules Manager, the ORDERING and CONSUMPTION event management policies can be used to control the execution of specific rules (may relate to your second question).
Please let us know if you have additional questions.
Thanks,

Question about expressions inside AE

I don't even know what to search for on google to find the answer. So after an hour trial and error inside AE and failure in google search, I'm coming here to seek help.
I have a plugin (RedGiant Sound Keys) that is giving values as keyframes for every frame. And the values go like: 0, 4, 7, 3, 5, 0, 0, 5, 6 ....
In other words, they fluctuate between zero and, say, 10.
I want another layer to get this value, but add it to itself every frame. I used to do QBasic programming and it was very simple there. Just something like x = x + (value from the Sound Key plugin)
But I don't know how to do this in AE.
Right now I have this:
x = (thisComp.layer("sound").effect("Sound Keys")("Output 1") * 0.5);
x;
What I really want is:
x = x + (thisComp.layer("sound").effect("Sound Keys")("Output 1") * 0.5);
x;
But it doesn't work.
Can someone help me please?

AE does not store persistent temporal variables. you have to accumulate them manually and write your own loops.
Expression Speed and Frequency Control
Soundkeys has an accumulate mode built-in, also, so rather than put up with complex expressions, simply use a duplicate instance of the effect and tweak the values.

Question about expressions that result in strings with quotes

Without jumping into too many of the details, I want to do something like this:
<h:outputLink onclick="someJSFunc('#{somebean.someVal}')" />
When the expression results in a string that contains apostrophes, the code naturally fails. Pre-JSF, I simply used a JSP scriptlet that took the value and passed it to a method that encoded it (quotes became an HTML code, etc). However, I don't know how I can achieve the same results with JSF...
Any ideas???

Are you using the latest RI? I'm looking at the source code, and the default response writer seems to escape quotes as """ when writing attributes, as it should for HTML.
If you do have the latest RI, what sort of error are you getting?

Simple question about Expression Builder

#{mybean.it1.value}
I need to know if inputText it1 is empty or not and to assign the boolean value to another property of another component.

you can check using the value of your inputtext :
ex : #{bindings.title.inputValue}
#{(bindings.title.inputValue==null) or (bindings.title.inputValue=="")}
if there is no exp in value att you can set att to dummy value in binding
by add variable of type string to executable and it to binding

Two Questions about Airport Express

All, I am a recent convert to using a Mac so bear with me.
I have two questions about the Airport Express.
Question if I buy one in the USA, I will visiting this week on holiday,can I use it the UK with a UK adaptor/apple plug?
Can the Express be used with my current wireless network, using a Netgear DG834G V4, I have read lots in the forums about putting a $ sign in front of the WPA password?
Any help and advice gratefully received.

Hello andixbox. Welcome to the Apple Discussions!

Yes, but at least two things to consider:
o The US version of the 802.11n AirPort Express Base Station (AXn) only supports radio channels 1-11 in the 802.11g radio mode. Channels 12-14, used in other countries outside the US will not be available.
o The AXn supports both the 2.4 and 5 GHz radio bands for 802.11n. The 5 GHz band is restricted in certain countries (like the UK) so operating in this mode may get you unwanted attention.
That should be okay then because the Netgear broadcasts on channels 1-11. I hadn't appreciated the 5 Ghz band, but having checked both US and UK Apple sites the techspecs both mention 2.4 Ghz and 5 Ghz.
Can the Express be used with my current wireless network, using a Netgear DG834G V4, I have read lots in the forums about putting a $ sign in front of the WPA password?
If your intent is to have the AXn join the Netgear as a wireless client, then yes it should work. The "$" requirement was for WEP. This shouldn't be necessary for WPA or WPA2.
I intended to use the AXn as an range extender, but you mention wireless client, is that something different?

[IPCC Express] Questions about database fields

Hello,
I'm developing some reports for Cisco IPCC Express.
During the development, a lot of questions came out related to the definition of some fields:
- In ContactCallDetail, what is the difference between transfer and redirect a call?
- In ContactCallDetail, what is the difference between transfer = 1 and contactType=5? Both are related to transfering a call.
I'll appreciate any help you can give me.

Few questions about Airport Extreme/Express

I have a few questions about Airport extreme/express:
1 Can you access hard drive trough express?
2 I have cable NOT wireless modem. What would be the best option (speed-wise) to connect to internet- connect modem to Extreme and access internet wirelessly from it? To connect modem to Extreme and imac?
3 How fast is read/ write from hard drive connected to Extreme?
4 How many hard drives can you connect to Extreme (or Express if that is possible)?
5 Can you remotely sync Ipod nano/ shuffle using Extreme?
I really hate wire clutter around my desk. What I intend to do is to connect hard drives and printer to Airport Extreme and access them remotely. That would leave empty desk:).
Thanks

1. You cannot connect a hard drive to the Airport Express USB port.
2. The speed of wireless networking is faster than the speed of most cable internet services. Therefore, you won't notice any difference in your internet connection speed between (a) a cabled connection directly between Mac and modem or (b) a wireless connection between Mac and base station and modem.
3. Apple has not published any specs on the speed of hard drive access for the Airport Extreme N Base Station. Several people have posted their own measurements (do a search in this discussion forum), and generally those results are not very good.
4. Apple has not placed a limit on the number of drives you can attach to the Airport Extreme N Base Station (with use of a hub). How many do you want to connect?
5. You cannot remotely sync an iPod using the Extreme Base Station.

HT201303 hi just got my new apple ipod touch i need to update my security information other wise it wont let me download apps it says to enter three questions about myself and i get to the third question and it wont let me enter the third question

hi just got my new apple ipod touch and to download apps it wants to add questions about myself for more sercurity information. i get up to question 3 and it wont let me select a question but it will let me write an answer so i just pressed done and then it says i cant carry on because ive mised out information when it wont let me do a question!

Welcome to the Apple community.
You might try to see if you can change your security questions. Start here, change your country if necessary and go to manage your account > Password and Security.
I'm able to do this, others say they need to input answers to their current security questions in order to make changes, I'm inclined to think its worth a try, you don't have anything to lose.
If that doesn't help you might try contacting Apple through Express Lane (select your country, navigate to iCloud help and enter the serial number of one of your devices)

Question about autodiscover in case of multiple bound namespace

Hi Experts,
I have a question about the autodiscover behaviour. Let's assume we have the below infrastructure:
SiteA :
MBX-Server-SiteA : Member of a DAG
CAS-Server-SiteA : outlook anywhere url = siteA.domain.com
SiteB :
MBX-Server-SiteB : Member of a DAG
CAS-Server-SiteB-1 : outlook anywhere url = siteB-1.domain.com
CAS-Server-SiteB-2: outlook anywhere url = siteB-2.domain.com
We have DB-1 and DB-2 that have copies in both MBX servers.
My question is how does exchange select the access URLs to return in the autodiscover process? I know that it depends on where the mailbox is hosted but can't find details about the process in the technet articles.
Thanks.

There's quite a few details that are involved in the Autodiscover process. First of all - probably the most important thing is that there are 2 stages to the whole process.
In the first stage, the client is simply concerned with getting the address of a CAS server that will help it further. We'll keep things simple and assume your scenario where the client is located inside the network and is domain-joined. The details of the
LDAP query are detailed in
this link. (At the time I was investigating this I've actually went ahead and ran the queries using the ldp.exe client against the Configuration partition of the respective AD domain - it's worth seeing the actual responses.) An interesting trick here is
the 'keywords' attribute that's stamped on those SCP entries. The reason behind it is that you don't want a client located in a site to go half across the globe in order to connect to a CAS server, when there's one available in its own site. One simple way
to get the 'keywords' attribute stamped is through the Set-ClientAccessServer cmdlet, using the -AutodiscoverSiteScope parameter. In your example, you'd probably want to run it against the CAS server in Site A and specify the name of the corresponding AD site
('SiteA') and correspondingly against the 2 CAS servers in Site B (using 'SiteB'). Once the client has got the response to his query, it will attempt to select one server that's handling the site he's in (essentially it will filter the results based on 'keywords'
-contains <client-site>). Now that we got our endpoint we can go to stage 2.
In stage 2, the client will actually use EWS in order to query the Autodiscover service itself running on our target server. There are 2 possible interfaces of accessing the Autodiscover service: POX (Plain Old XML) and SOAP. POX will be targeting the ../Autodiscover.xml
URLS, while the SOAP one will be using ../Autodiscover.svc URLs. Details about this including some hardcoded parts are
here. What happens next is detailed in point 3, section 2.1 The Autodiscover Process
here. This last link is the key to the whole process:
"It provides a list of CAS that has AutodiscoverSiteScope information set for the
Associated AD site of the Database where the client Mailbox is located."
In other words, the CAS is smart enough to return the URLs belonging to a CAS server in the AD site where the client's mailbox' database is active.
My advice is to test this on your scenario. Tests can be done here first-hand: the Outlook's tray icon Test E-Mail AutoConfiguration can be used or alternatively - if you want to see the details in the communication - SoapUI
for the SOAP access method, for POX there's an extension called 'Postman for Chrome' that can be used. I've used all these in my tests back when I was fighting conflicting results from the articles around the web about Autodiscover.
That's a long way of saying we get the AutoD URL of a CAS server closest to the workstation, which then provides the configuration to use which are the the URLs closest to the mailbox :)
By all means look at the SOAP response, but Outlook will only use POX. Lync does SOAP along with other 3rd party apps.

Best Practices: Question about Passing DataSet to Crystal through C#

I have used the tutorial provided by Business Objects and have successfully passed a dataset from C# code to Crystal Reports.
I have a few questions about "best pratices" though.
It appears that when passing the dataset to crystal then you no longer have the ability to put SQL Expressions in the report anymore otherwise errors will occur.
So, I'm trying to come up with a way to have a custom field in the SELECT statement and have it show up on the report as a field. So, in the below example I created a custom SQL field called TIMES7 in the query.
"Select CLM_ID, CLM, PAID_111X, *(PAID111X * 7) As TIMES7*_ From WIKI.MULCRICKET WHERE CLM_ID < 5"
If I create a formula field in Crystal and set it's value to {MULCRICKET .TIMES7} then it works like a hybrid SQL Expression at run-time.
This does work but has issues because the database field doesn't really exist in the design environment which causes error when the formula is saved. But it does work at run-time.
I was wondering if their was a best practice for this?

So why are you using a formula that doesn't work? If it errors in the designer it's telling you it's not supported.
Drop the formula into a filed and hide it if you don't want it displayed, this way it gets into the record selection formula.
"Best Practices" is don't use formulae that won't verify in the Designer. "If it doesn't work in the designer it won't work in code"
If you need to add an "unknown" field at run time then use RAS to insert the field.

Question about Stacking

Hello Everyone,
I have a quick question about stackwise plus technology. I would like to confirm that there is no redundancy at the ethernet switch port in terms of a physical problem. The reason I ask is that we are deploying stacked switches shortly to ensure high availability but curious to know whether anyone has seen issues with physical ports failing and not the chassis/PSUs. I understand that Etherchannels can be used but we have security cameras that cannot suffer any outages and would be connected to a single port on the stack. I'm guessing that my option is to monitor the Switch Ports statistics via SNMP and move the camera to another port if this ever happens.
Thanks in advance.
Cheers.
Evan

Sure, ports can fail without the whole switch failing, but edge redundancy, such as using dual links (often configured as a bundled channel), between the host and two stack members addresses both switch port failure and stack member failure.
Unless your security cameras support dual links, your going to have a single point of failure at the edge port.
Next best options, as you've already noted, would be to have, on-line, "warm" spare ports that you can quickly repatch into. Ideally you have enough spare ports to allowing repatching in case a whole switch member fails.
(BTW, when you have spare ports, you don't have to set aside a whole stack member, sitting empty. For example, instead of having a dual stack with only one switch member populated, and the other not at all, split the populated ports across both stack members. That way, if a stack member fails, you don't lose all your hosts, only half. [With cameras, depending on their views, you might be able to overlap their coverage across multiple stack member.])

Then click on 'Password and Security' on the left-hand side of that page and on the right-hand side you might see an option to send security question reset info to your rescue email address.
If you don't have a rescue email address set up then go to Express Lane and select 'iTunes' from the list of 'products' in the middle of the screen.
Then select 'iTunes Store', and on the next screen select 'Account Management'
Next choose 'iTunes Store Account Questions' or 'iTunes Store account security' (it appears to vary by country) and fill in that you'd like your security questions/answers reset.
You should get an email reply within about 24 hours (and check your Spam folder as well as your Inbox)

Newbee questions about XE application builder

Hi
I find that Oracle support someting that we can use to build some real database driven applications

2-Does any one use it to build a real world application that works some where in some business place ?
3-what is its behind code and technology , does it use JSF and managed Beans ? how i can see the generted codes ?
Thanks

Hello,
Here's the link to the Application Express Forum Oracle Application Express (APEX)
