Compiler Options for Web App

I am working on a training course that deploys a web application to a web server of my choice. I have Tomcat setup and I also have used the embedded server in JDeveloper 10g. There are several exercises that I have partial code written. When I try to deploy the app to test one of the exercises I get compiler errors on other parts of the web app.
Is there any way I can tell the compiler to only compile those things that have changed or still deploy with errors? I was able to get it to deploy by commenting out several pieces of code, but this is not my optimal solution.
Thanks

yes, mod_plsql for Apache (the core of Oracle 9iAS) allows you to make PL/SQL calls from a browser environment and return HTML. the entire Oracle Portal product is written using this mechanism.
learning JSP from scratch, and learning how to manage security, database connections and record sets would be a daunting task. if you want to learn Java, great. it's my favority web language. however, if you have PL/SQL experience and a need to get information to the web, use mod_plsql and generate dynamic content via PL/SQL and the database.
good luck,

  • Detail on High Availability options for Web Apps

    Hi,
    I do really struggle to locate actual information on Azure Availability offerings / capabilities...as an Infrastructure Architect it has bugged me for years now with Azure offerings!
    Something that simply states the availability within any local DC and options for true HA over 2 or more DC's.
    We are moving away from using Web Roles to Web Apps for solutions for our clients. I understand the principles of fault domains, etc. with Web Role requirements for min. of 2 to (mostly) avoid MS update disruption within a single DataCenter, but cannot locate
    similar info. with regard to Web Apps.
    Really appreciate if someone could point me to some appropriate detail as I've failed....
    (Also, cannot find anything on DocumentDB....)
    Many Thanks,
    Lee

    Hi,
    High Availability of a running service always comes with a cost, and priorities will be app-specific. If it's the web tier, then you may indeed want to consider hosting in multiple geo's. If it's a backend processing tier, sometimes it's "ok" to
    let a service go offline, as long as requests are queued up. If it's the storage system (preventing queueing of messages), perhaps an alternate queue in a different data center could be available for redundancy purposes.
    I would request you to check this article:
    https://msdn.microsoft.com/en-us/library/azure/dn251004.aspx
    Hope this information helps.

  • How many display options for Web Apps are there?

    I know this is going to sound stupid,
    But are there only 2 ways to show web apps?
    Basically - I want to get links to auto populate on one web app, pulling just links to another web page (this web page is one of the fields in another web app), but automatically updated when the category of the "linked to" web app has another product linked to it.
    I know what that reads like!
    The only thing is - these are separate web apps.
    The alternate/backup view of the first web app looks like this:
    Currently - the user has to manually add the links like this:
    Which is not ideal - I just want them to dynamically populate on the fly.
    Is this possible?
    Cheers, Dave

    Funny you say that - as the most obvious things appear in your brain immediately after posting a question... Will see how that works...

  • Problems with "save for web" app low quality messed up images

    Please help I have never had a problem with the "save for web" application before (over three years) I am currently running A.I. cs3 on windows vista. in the past whenever I save anything this way the images were always clean. as of yesterday everything I try to save through the save for web app the images are very low quality all the vector has jagged edges, it is very low rez looking and the file sizes are very small, half the size they normaly would be. What did I do to change the settings or better yet how can I get it back to the way it was.

    Thank you for your help I moved the folder but it still did not fix this problem. it is also not just the jpg option under the save for web app but all the setting ie. gif, png, ect. ect. Also the the files sizes are much less, example I exported a design as a jpg with the quality setting about 6 the file size was 374kb when I exported the same design through the save for web app the file size was only 45 kb on the quilty setting of 100. further more in the preview screen of "save for web" the original images as well as the optimized both look messed up. The "save for web" app has always worked for me in the past never a problem and I use this app alot so it is very important.

  • Custom module templates for Web Apps

    Just wanting to see if there's anyone out there who knows if the custom module templates from the September release are available for Web Apps?  I can't seem to get them to work.
    When placing {module_webapps,8168,a template=”/custom/wap-contract.tpl”} I get a "No Items Found" response. I would appreciate help as this would be very useful in building Web Apps and I can't find documentation on it
    Thanks

    They do work with Web Apps, I've been able to use it successfully. Here is the only documentation I can find on it so far:
    http://helpx.adobe.com/business-catalyst/partner/using-custom-templates-modules.html
    Curious though, when  you get "No items found" that means there are no web app items to show. So we don't really know if your custom template worked or not. If you can get some items to show up and they use the default layout, then we know something is wrong.
    Hope this helps,

  • JavaHelp for web app?

    Hello,
    I'm trying to include JavaHelp for our web application.
    Has anyone used this tool or any other tool with javascript for displaying help for web apps?
    I tried to follow the browser demo that is in applet and comes with javahelp zip. It worked fine for me, but when tried to follow the same setting for the web application, I am getting this error.

         <PARAM NAME = HELPSETNAME VALUE ="GAPIHelp">
    </Applet>Also, since applet approach is not that much favored, do you know if any other way to include this tool within web applications or any other tool that would do the same thing?
    Any input is greatly appreciated.
    Thanks,

    Yes, as long as you conform to what the HelpSet specifies you can use Servlets / JSPs.

  • Do we have a built-in option for web based tool in Nexus 5548UP switches for management purpose?

    I have purchased Nexus 5548UP switch, i want to know if we have a built-in option for web based tool to manage and configur it just as ASA have ASDM. If there is no such options then what are the options available that can be freely available and can be used to get performance monitoring done.
    Message was edited by: Praveen Varun

    DCNM (Data Center Network Manager) runs on a server (Windows, RHEL or Solaris) and can be used to manage Nexus devices. It's free for Nexus 1K through 5K devices (paid license required for Nexus 7K management).

    There is not a "built-in" management product like ASDM for ASA.

  • What happened to the add to home page option for web pages. Can't find it.

    What happened to the add to home page option for web pages. Can't find it.

    Try stopping Safari followed by resetting your phone: double-tap the home button, locate Safari at the bottom (swiping if necessary), tap and hold until it wiggles, tap the minus sign.  Now reset: hold the on/off and home buttons until you see the Apple logo (ignore the off slider that appers first), then release.  If it still is missing you may need to restore your phone, which will put a fresh copy of the iOS on your phone (see http://support.apple.com/kb/HT1414).

  • Set Disable or Expiry Date for web app item via Edit form

    I have a user that wants to delete a web app item from a secure zone edit form, but they are not the owner of that web app item.  All items in the web app were imported via a csv file and hence do not have a 'submitted by' user id assigned.
    Is it possible to Disable a web app item using a web app Edit form?  or alternatively, is it possible to set the Expiry Date of a web app item using a web app Edit form?
    Thanks
    Dave

    Sorry Brian, but I'm not sure that answers my question.
    Sure, I can create a single web app item for every single client of my customer, manually.
    Sure, I can create and 'allocate' that single web app item to each customer manually.
    I pray the customer doesn't have hundreds of clients. And I would have to teach my customer how to do this convoluted process for every new client.
    But the one thing this doesn't do is answer the question of updating the value of units held.
    It seems the order module remains the closes to what I am looking for in that it allows an equation, and is automatically customer specific.
    However, I am looking for a way to achieve a single daily update by the customer as to the value of the units held by each client. This can be done via the product module - update price. But this does not update existing orders. Exisitng orders are fixed at the price on the day. The customer wants to update the value once, in one place, and have that amend all existing 'orders' to reflect the new total value of units held by each individual client, and to have this show in each client's member area.
    If you can think of a way of doing this in webapps or via the order module, this is what I am looking for. Anyone?

    Hello Daniel,

  • Advance Options in Web APP Designer

    Hi,
      Although we have BI for NW04S , we are still using Web APP designer3.5. Using the Drop down box we can have a dropdown based on  a info object ( for example if the report has a charateristics/info object "0CALQUARTER", I can easily build a dropdown which can show all the quarter that the infoprovider has and then user can select that perticular Quaerter or All Querter( or with another drop down for Year). This combination allows the user to see the data for a perticluar( or for all year) and for a perticular quater( or for all quarter in that Year, selected in previous dropdown). What I really want to do a rolling quarter( for example ( would like to show the data based the current and previous 3 quarter based on a drop down, or only current quarter etc).. One way to do this is to have the report using variables replaced by user exit. Is there any other way directly in the web app desiner?
    Thanks
    Arun

    If you are talking about different screens for the associated reports - you could have a user entry variable for quarter and the value for the same can be passed through the URL and you can use the required offsets in the query design..

  • Seperate Log file for web app

    I am running a web app under WS 6.1 and uses the java logging.
    I i turn the logging to "finest" on the virtual server, i get my app finest and the vertual server finest in the same file!
    What i need is to seperate these 2 in two files.
    or is it possible to say that for the package com.foo.bar i wanted to be finest, but the rest i wanted to be warnning?
    Thanks,

    Kumar,
    I don't know the answer to your "separate log per web-app" question (sorry :-(, but regarding your property changes -- if you are referring to the XML configuration files (like "orion-web.xml"), then they do not get overwritten when you redeploy. You must either edit them manually, or delete all the files/directories created when you first deployed your application before redeploying -- that way, they will be created again when you deploy.
    By the way, why are you so reluctant to upgrade to the latest version of OC4J?
    Hope this has helped you.
    Good Luck,
    Avi.

  • Power Query - How to format options for Web.Content()?

    I am trying to access a web api which can return data in either JSON or XML. When connecting with Power Query I get a "400, Bad request" error though and I suspect it could be due to Power Query not explicitly providing accepted Content-Types
    in the request. Anyone know how to add options to the Web.Content() request?
    http://office.microsoft.com/en-001/excel-help/web-contents-HA104112310.aspx
    Thanks!

    I believe the default reponse content-type is JSON. It doesn't serve Power Query with anything but an error response though and with the help of Network Monitor I caught a bit more details (in Swedish).
    Request:
    Http: Request, GET /platsannons/matchning, Query:lanid=1
    Command: GET
    + URI: /platsannons/matchning?lanid=1
    ProtocolVersion: HTTP/1.1

    And the API can be found at:

    Would be great to be able to define custom headers to the request through options for cases like these. Thanks for the reply!

  • Modifying Advance CSV export options for Web Intelligence

    When we download a Webi report as a CSV(witha dvance options)
    In the CSV download advanced options -- We have options for specifying the 'Text Qualifier which is ( " and ' ) and Delimiter (, and ; and tab)
    I would like a 'none' option for the 'Text Qualifier' i.e the output columns of the csv should not be enclosed by single or double quotes....
    Any suggesstions as to where I can modify this.

    1. have you created any hierarchy in the universe ? after creating required hierarchy, in the webi report you need to enable drill mode.
    2. you can use opendocument url with sReportName parameter. Please check this doc for details: http://help.sap.com/businessobject/product_guides/boexir3/en/xi3-1_url_reporting_opendocument_en.pdf
    But for this you need to export the report to InfoView.
