SPEL: Can I use java expressions for complex rendering?

Hi
I would like to avoid complexity in extending controllers and VO's in iProcurement by adding some rendering control to my page attributes such that the value of "rendered" is a more complex SPEL function.
E.g.:
normally I could use:
rendered="${oa.VO.isFieldRendered}"
where the above attribute exists in the VO.
However, I would like not to have to create a new Attribute, but use the following:
rendered="${oa.VO.Field.equals("Y")}"
Does anyone know if this kind of thing is possible?
Cheers
Chris

Hey Jon! Will e-mail ya later!!
Tapash: Am trying to use an existing VO field to determine the rendering of a page item. The current field has a Y/N value, not boolean which the render SPEL generally uses.
The only way I know how to do this is to extend the VO and add a new calculated boolean field. I can do this, but was hoping that SPEL might provide an alternative..
Thanks
Chris

  • Can i use java only for database transaction with vb as a front end

    Hello All.
    I am sorry,i don't know whether this location is the correct location to post my question or not
    I have developed one application using complete vb only. That is completly desktop appliation and not suitable for centralized database. Is there any facility to keep my front end as same (vb application) and for the database transaction can i use jdbc? Is there any possibility to do that like View is vb based application and the database connectivity is only jdbc
    If my thought is wrongplease execuse me.
    thanks in advance

    Sounds like a really bad choice even if it was possible.

  • Can I use Signal Express for multiple customers for only the one time $699?

    How do I go about distributing Signal Expresss applications to multiple customers?

    Hi Nutter,
    Unlike LabVIEW, Signal Express doesn’t have any file distribution capabilities.  If your application uses only basic features, you could install the free LE version of Signal Express on as many computers as necessary.  If you need the full capabilities of Signal Express, however, you would need to purchase a license for each customer.
    An alternative to paying for Signal Express for each customer deployment would be to generate LabVIEW code from the Signal Express project and create an executable.  This process is described in the Knowledge Base articles Generate LabVIEW VIs from Signal Express and Deploying VIs generated in Signal Express.  Note that this method requires that you have LabVIEW installed on your development computer with Application Builder capabilities.

  • Can I use Airport Express for printing and Ethernet printing at same time?

    I've been trying to set up a couple of laser printers that were given to me recently. The printers are Apple LaserWriter 16/600 PS and Samsung CLP-510. The reason I'd like to have both up and running is because the black toner for the Samsung costs twice as much as the toner for the LaserWriter. I have two questions that I am hoping someone will be able to answer.
    1) The CLP prints a test page just fine. I was finally able to get the Samsung printing while directly connected to my PowerBook G4 via usb (I had to install a Xerox Phaser 6100 driver to do so!). Today I tried putting the usb into my Airport Express (which I use for my portable internet and airtunes) and now the printer does not respond. When I try to add the CLP as a bonjour printer, I get an error adding the printer and the printer does not respond. Can someone offer some advice as to how and if the CLP may work via the Airport Express?
    2) The LaserWriter prints a test page just fine. I purchased a transceiver (albeit not an Apple transceiver - this one says Asante Friendlynet, the guy I bought it from said it would work though). The transceiver is connected to the Ethernet port on the printer - and I have a yellow ethernet cable (?) running from the transceiver to the ethernet port on my computer. I read somewhere on the internet that I need to turn on Appletalk in order to use the printer via ethernet but when I went into my network settings to do that, there was a warning that I could not turn on appletalk for ethernet without forsaking my airport. Can someone offer some advice as to how and if the 16/600 PS may work via ethernet without disrupting my (working) airport express? Also - I did not receive any software or drivers with this printer but I read that I may not need to (they come with Tiger - ?) Is anyone able to confirm this?
    Any help would be TOTALLY appreciated!

    Hello Kappy! Thank you for taking the time to reply to my question.
    I should update you at this point to say that I can add the 16/600 PS printer through a process that I found called 'Direct IP printing over ethernet'. (I think I've done this correctly - but I honestly have no idea about network stuff). Here's what I did:
    -went into system prefs and looked at the network settings under built-in ethernet tab. Under TCP-IP I found the IP address of my network host.
    -In the Printer Setup Utility I tried to manually add the 16/600 PS printer. In the Printer Browser window, I selected IP Printer.
    -Under IP printer, I selected LPD Protocol. I inserted the IP address copied from my network settings (above) in the address bar. In the Queue bar I typed in the name of the printer 'Apple LaserWriter 16/600 PS'.
    -Again in the Printer Browser box I gave the printer a name and location. Finally, in the 'print using' box I selected Apple and then chose the model from the drop down list. 'Apple LaserWriter 16/600 PS fax v.2014.016'
    -I got a dialogue box that asked about other installable features - clicked ok.
    -when I tried to print a Word document, the Apple LaserWriter driver opened up and appeared in my dock and then I got an immediate error saying "network host ---.---.--.--- is busy, down, or unreachable..."
    -I tried to repair permissions, but it did not resolve my issue.
    -I noticed that even after adding the 16/600, it did not show up as a bonjour printer, but remained visible as a printer in my list (although grayed out).
    I did some troubleshooting and the best I could find as a close match for my problem was that perhaps I had entered the name incorrectly in the Queue box...? If anyone knows how to find the appropriate name to insert I would sure appreciate knowing.
    Finally - you should probably know that I received this printer from someone else. I guess I'm wondering if I need to be resetting network settings on the printer somehow? The test page lists the following:
    Ethernet (Address: 08:00:07:84:78:e9)
    EtherTalk: PostScript
    NetWare: AutoSelect
    TCP/IP: AutoSelect
    IP address: 0.0.0.0
    And - now finally, to answer your questions (the best I can, that is)
    I did connect the yellow network cable directly into my laptop (right side, 4th input, counting away from me). I have a portable internet modem that plugs into my wall (for power) and then has a cable (Ethernet?) that goes into my Airport Express (LAN port?). I have no other router and there are no other inputs or outputs on my modem. My Airport Express has only one input for the modem, one mini input for airtunes, and one usb input (in which I have a cable connecting to my other laser printer (now working wirelessly via Airport Express!!)
    Should I have these cables hooked up differently?
    What is a Phonenet adaptor? My internet is provided via a cable service (not DSL). It is wireless and portable - I can take it to any major city in Canada and it works as long as it is plugged into a power source and near a window.
    I really appreciate any help you can offer. At this point I must have spent the better part of almost two weeks trying to get these older laser printers up and running.
    Thank you again.

  • Can I Use Airport Express for Airplay and a non-apple router with streaming capabilities on the same network?

    I want to do the following things but can't find one device that fits all purpose.
    Wi-Fi router that has USB port to share external hard disk wirelessly to all devices (Mac, Samsung Smart TV, PC, Ipad, Iphone) along with inbuilt torrent download capability that also has a 3.5mm jack to do airplay.
    Greedy? Yes I know but why can't we have it all I ask.
    Airport Express severs Wifi Router + Airplay purpose
    Then there are other non-apple routers in market that satisfy my need to attach external hard disk and stream to the devices mentioned (Note: Timecapsule will not stream to my Smart TV)
    So I am thinking why not connect both Airport Express and a second non-apple router and get best of both worlds.
    Is it possible?
    Thanks in advance.

    I currently have a D-Link DI-604 broadband router with windows computers.  How can I add wifi to the network for use with ipad?  Can I use AirPort Express?

    Yes. You can directly connect an 802.11n AirPort Express Base Station (AXn) using an Ethernet cable. The AXn would then just need to be configured as a bridge to allow the D-Link to continue to provide both NAT & DHCP services for all network clients connected to either router.
    In this configuration, the AXn would broadcast a wireless network for your wireless network clients to connect to.

  • Can I use airport express to extend my network AND stream iTunes???

    I have an airport extreme connected to the cable modem and sending a signal out to my home network. I also have a powerbook and an airport express connected to the home stereo.
    My question is, can i use the express to extend my extreme signal (to reach the back yard) and stream music from itunes at the same time? The set up utility seems to suggest that you do one or the other.
    Thanks!

    Are you sure you configured the Express to extend the Extreme's network? If you use the standard setup, the two base stations will be indistinguishable, i.e. you'll only see one entry for the wireless network.
    If you were connected to the Extreme when you configured the Express, try turning off Airport in the Airport menu and then turning it back on. The computer should pick up the stronger signal at that point.

  • I have an airport extreme and express, if I use the extreme as a base station connected to my old router can I use the express to extend the signal while also creating a new network that only I can use?

    I have an airport extreme and express, if I use the extreme as a base station connected to my old router can I use the express to extend the signal while also creating a new network that only I can use? Essentially having two wifi connection off the same network? If so how do I set this up?

    Extending using a wireless connection always results in a performance compromise.
    If the Express is going to extend using a wireless connection, then the Express will need to be located about half way between the AirPort Extreme and the general area where you need more wireless coverage. The more that you have line-of-sight between the Extreme and Express, the better the network will operate.
    Remember......the Express can only "extend" the quality and signal speed that it receives, so it needs to be located where it can get a very good signal from the Extreme. Although Apple cleverly uses the term "extend", a more accurate term for the Express would be "repeater".
    If the Express will extend by connecting to the Extreme using a permanent, wired Ethernet cable connection......highly recommended for best performance.....then the Express can be located exactly where you need more wireless coverage. There is no signal loss at all through the Ethernet cable, so the Express gets a full speed signal no matter where it might be located.
    Post back to let us know which way to you want to go.

  • Is there a way to turn the wireless capabilities off on an AirPort Express?  I have an AirPort Extreme as my main router and use the express to just extend it. I only really want to you use the express for hard ethernet connections

    Is there a way to turn the wireless capabilities off on an AirPort Express?  I have an AirPort Extreme as my main router and use the express to just extend it. I only really want to you use the express for hard ethernet connections. For whatever reason when I have my express extend my wifi at home the download speed from just the express is absolutely terrible, drops to about 1.5 mb compared to when it's on the extremes part of the network the speed goes up to 50-75mb. These terrible download speed really only affects the iPhones as my MacBook Pro usually gets the good speed no matter where it is. I don't believe there is anything wrong with my phone because if I am in the part of the house that uses just the extreme the download speeds on the iphone goes up to 50-75mb. As a note I have an AirPort Extreme on the top floor of my house (second floor) that's where my modem is located. On the first floor that's where one airport express is located. I also have another airport express in the basement that is accessed by my landlord. Any thoughts on how to fix this would be helpful.

    It appears that your networking goals with the AirPort Express is to use it as a wireless Ethernet bridge instead of using it to extend the wireless range of your AirPort Extreme. The latter requires that the Express Wi-Fi radios be enabled.
    If you intended to use the Express as a wireless bridge, you just need to reconfigure it to "Join a wireless" network instead of "Extend a wireless network."
    For whatever reason when I have my express extend my wifi at home the download speed from just the express is absolutely terrible, drops to about 1.5 mb compared to when it's on the extremes part of the network the speed goes up to 50-75mb.
    In an extended network, the placement of the extending base station is critical as it can only extend the wireless network at the bandwidth at which it receives it.
    Please check out the following AirPort User Tip for details on optimal base station placement.
