  • starting rails in test environment

    - by Brian D.
    I'm trying to load up rails in the test environment using a ruby script. I've tried googling a bit and found this recommendation: require "../../config/environment" ENV['RAILS_ENV'] = ARGV.first || ENV['RAILS_ENV'] || 'test' This seems to load up my environment alright, but my development database is still being used. Am I doing something wrong? Here is my database.yml file... however I don't think it is the issue development: adapter: mysql encoding: utf8 reconnect: false database: BrianSite_development pool: 5 username: root password: dev host: localhost # Warning: The database defined as "test" will be erased and # re-generated from your development database when you run "rake". # Do not set this db to the same as development or production. test: adapter: mysql encoding: utf8 reconnect: false database: BrianSite_test pool: 5 username: root password: dev host: localhost production: adapter: mysql encoding: utf8 reconnect: false database: BrianSite_production pool: 5 username: root password: dev host: localhost I can't use ruby script/server -e test because I'm trying to run ruby code after I load rails. More specifically what I'm trying to do is: run a .sql database script, load up rails and then run automated tests. Everything seems to be working fine, but for whatever reason rails seems to be loading in the development environment instead of the test environment. Here is a shortened version of the code I am trying to run: system "execute mysql script here" require "../../config/environment" ENV['RAILS_ENV'] = ARGV.first || ENV['RAILS_ENV'] || 'test' describe Blog do it "should be initialized successfully" do blog = Blog.new end end I don't need to start a server, I just need to load my rails code base (models, controllers, etc..) so I can run tests against my code. Thanks for any help.

  • Get the id of the link and pass it to the jQueryUI dialog widget

    - by Mike Sanchez
    I'm using the dialog widget of jQueryUI. Now, the links are grabbed from an SQL database by using jQuery+AJAX which is the reason why I used "live" $(function() { var $dialog = $('#report') .dialog({ autoOpen: false, resizable: false, modal: true, height: 410, width: 350, draggable: true }) //store reference to placeholders $uid = $('#reportUniqueId'); $('.reportopen').live("click", function (e) { $dialog.dialog('open'); var $uid = $(this).attr('id'); e.preventDefault(); }); }); My question is, how do I pass the id of the link that triggered the dialog widget to the dialog box itself? The link is set up like this: <td align="left" width="12%"> <span id="notes"> [<a href="javascript:void(0)" class="reportopen" id="<?=$reportId;?>">Spam</a>] </span> </td> And the dialogbox is set up like this: <div id="report" title="Inquire now"> HAHAHAHAHA <span id="reportUniqueId"></span> </div> I'd like for the id to be passed and generated in the <span id="reportUniqueId"></span> part of the dialog box. Any idea?

  • Not able to play videos (from youtube) in WebView

    - by user1205193
    I am using a webview to display a video (could be from youtube or vimeo) in my app. In order to not load the video webpages in the default Android Browser, I am also extending the WebViewClient so I can override the shouldOverrideUrlLoading method. This way the video webpage loads successfully in the WebView. However, when I click on the embedded video on the WebView, it does not play. If I do not override the shouldOverrideUrlLoading method, and let the video webpages load in the default Android browser, the videos work just fine. Any ideas why the videos are not working in the WebView? Also, the main reason why I overrode the shouldOverrideUrlLoading method is because if I do not do that, then when I exit the Android browser to come back to my activity (by hitting the back button on the phone), I see a white screen. Upon hitting the back button twice, I am able to get back to my Activity. I am using the emulator to do this test. Here is my code: public class YoutubeLink extends Activity { WebView myWebView; String video_url; private class HelloWebViewClient extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { view.loadUrl(url); return true; } } @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.youtubelink); //Retrieving data from ListSample.java Bundle extras = getIntent().getExtras(); if(extras !=null) { video_url = extras.getString("video_url"); Log.d("inside YoutubeLink.java", video_url); } myWebView = (WebView) findViewById(R.id.web); myWebView.getSettings().setJavaScriptEnabled(true); myWebView.setWebViewClient(new HelloWebViewClient()); myWebView.loadUrl(video_url); } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if ((keyCode == KeyEvent.KEYCODE_BACK) && myWebView.canGoBack()) { myWebView.goBack(); return true; } return super.onKeyDown(keyCode, event); }}

  • .NET 3.5 DataGridView Wont Save To Database

    - by Jimbo
    I have created a test Winforms application in Visual Studio 2008 (SP1) to see just how "RAD" C# and .NET 3.5 can be. So far I have mixed emotions. Added a service-based database to my application (MyDB.mdf) and added two tables - Contact (id [identity], name [varchar] and number [varchar] columns) and Group (id [identity] and name [varchar] columns) Added a DataSource, selected "Database" as the source, used the default connection string as the connection (which points to my database) and selected "All Tables" to be included in the data source and saved as MyDBDataSet Expanded the data source showing my two tables, selected the "Group" table and chose to display it as a DataGridView (from the dropdown option on the right of each entity) and dragged it onto Form1, thus creating a groupBindingNavigator, groupBindingSource, groupTableAdapter, tableAdapterManager, myDBDataset and groupDataGridView Press F5 to test the application, enter the name "Test" under the DataGridView's "name" column and click "Save" on the navigator which has autogenerated code to save the data that looks like this: private void groupBindingNavigatorSaveItem_Click(object sender, EventArgs e) { this.Validate(); this.groupBindingSource.EndEdit(); this.tableAdapterManager.UpdateAll(this.myDBDataSet); } Stop the application and have a look at the database data, you will see no data saved there in the "Group" table. I dont know why and cant find out how to fix it! Googled for about 30 minutes with no luck. The code is auto-generated with the controls, so you'd think that it would work too :)

  • Linq to SQL - Failing to update

    - by Isaac
    Hello, I'm having some troubles with updating linq to sql entities. For some reason, I can update every single field of my item entity besides name. Here are two simple tests I wrote: [TestMethod] public void TestUpdateName( ) { using ( var context = new SimoneDataContext( ) ) { Item item = context.Items.First( ); if ( item != null ) { item.Name = "My New Name"; context.SubmitChanges( ); } } } [TestMethod] public void TestUpdateMPN( ) { using ( var context = new SimoneDataContext( ) ) { Item item = context.Items.First( ); if ( item != null ) { item.MPN = "My New MPN"; context.SubmitChanges( ); } } } Unfortunately, TestUpdateName() fails with the following error: System.Data.SqlClient.SqlException: Incorrect syntax near the keyword 'WHERE'.. And here's the outputted SQL: UPDATE [dbo].[Items] SET WHERE ([Id] = @p0) AND ([CategoryId] = @p1) AND ([MPN] = @p2) AND ([Height] = @p3) AND ([Width] = @p4) AND ([Weight] = @p5) AND ([Length] = @p6) AND ([AdministrativeCost] = @p7) -- @p0: Input Int (Size = 0; Prec = 0; Scale = 0) [1] -- @p1: Input Int (Size = 0; Prec = 0; Scale = 0) [1] -- @p2: Input VarChar (Size = 10; Prec = 0; Scale = 0) [My New MPN] -- @p3: Input Decimal (Size = 0; Prec = 5; Scale = 3) [30.000] -- @p4: Input Decimal (Size = 0; Prec = 5; Scale = 3) [10.000] -- @p5: Input Decimal (Size = 0; Prec = 5; Scale = 3) [40.000] -- @p6: Input Decimal (Size = 0; Prec = 5; Scale = 3) [30.000] -- @p7: Input Money (Size = 0; Prec = 19; Scale = 4) [350.0000] -- Context: SqlProvider(Sql2008) Model: AttributedMetaModel Build: 3.5.30729.4926 As you can see, no update is being generated (SET is empty ...)

  • Entity Framework POCO objects

    - by Dan
    I'm struggling with understanding Entity Framework and POCO objects. Here's what I'm trying to achieve. 1) Separate the DAL from the Business Layer by having my business layer use an interface to my DAL. Maybe use Unity to create my context. 2) Use Entity Framework inside my DAL. I have a Domain model with objects that reside in my business layer. I also have a database full of tables that doesn't really represent my domain model. I setup Entity Framework and generated POCO objects by using the ADO.NET POCO Generator extension. This gave me an object for each table in my database. Now I want to be able to say context.GetAll<User>(); and have it return a list of my User objects. The User object is in my business layer. Is that possible? Does that make sense or am I totally off and should start over? I'm guessing I need to use the repository pattern to achieve this, but I'm not sure. Can anyone help?

  • Jquery code breaks page Javascript

    - by Graham
    I required a function to remove URLs from <a> divs found within <div class="rj_insertcode">. Not being familiar with with direction to tackle this, I eventually mustered up the following Jquery code: <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <script src="jquery.min.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function(){ $('div.rj_insertcode a').each(function() { $(this).replaceWith($(this).html()); }); }); </script> </head> My site uses Joomla CMS and I was able to add the above script to the bottom of the template index.php. It works quite well and removes the links generated between the defined tags. My problem: Pages that also include JavaScript do not operate correctly. JavaScript appears to be disabled or not functioning. What can I change to ensure JavaScript still operates correctly, or is there another method I could adopt?

  • How to remove erroneous dependency from tycho build?

    - by sfinnie
    Context: Have built an eclipse update site using tycho but trying to install into target IDE fails. The update site builds fine; I can see it from a target eclipse installation and select the feature for installation. However, the dependency check fails at start of install as it can't find a declared dependency (org.eclipselabs.xtext.utils.unittesting). This shouldn't be a dependency: it was erroneously included in MANIFEST.MF for one of my eclipse plugin projects. I removed the dependency from the manifest and run mvn clean install. Build reported success. However when I try to use the newly built update site it still complains that the dependency to org.eclipselabs.xtext.utils.unittesting (a) exists and (b) can't be satisfied. So the question is: what else do I need to do to remove the dependency from the generated update site? Thanks for any pointers. PS: I know I could add the site for o.e.x.u.unittesting in the target eclipse installation so it can satisfy the dependency. However I don't want to do that; it's not needed for the feature to work and I don't want other users to have to add an unnecessary dependency.

  • Fluent NHibernate AutoMap

    - by Markus
    Hi. I have a qouestion regarding the AutoMap xml generation. I have two classes: public class User { virtual public Guid Id { get; private set; } virtual public String Name { get; set; } virtual public String Email { get; set; } virtual public String Password { get; set; } virtual public IList<OpenID> OpenIDs { get; set; } } public class OpenID { virtual public Guid Id { get; private set; } virtual public String Provider { get; set; } virtual public String Ticket { get; set; } virtual public User User { get; set; } } The generated sequences of xml files are: For User class: <bag name="OpenIDs"> <key> <column name="User_Id" /> </key> <one-to-many class="BL_DAL.Entities.OpenID, BL_DAL, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" /> </bag> For OpenID class: <many-to-one class="BL_DAL.Entities.User, BL_DAL, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" name="User"> <column name="User_id" /> </many-to-one> I don't see the inverse=true attribute for the User mapping. Is it a normal behavior, or I made a mistake somewhere?

  • Using the Queue class in Python 2.6

    - by voipme
    Let's assume I'm stuck using Python 2.6, and can't upgrade (even if that would help). I've written a program that uses the Queue class. My producer is a simple directory listing. My consumer threads pull a file from the queue, and do stuff with it. If the file has already been processed, I skip it. The processed list is generated before all of the threads are started, so it isn't empty. Here's some pseudo-code. import Queue, sys, threading processed = [] def consumer(): while True: file = dirlist.get(block=True) if file in processed: print "Ignoring %s" % file else: # do stuff here dirlist.task_done() dirlist = Queue.Queue() for f in os.listdir("/some/dir"): dirlist.put(f) max_threads = 8 for i in range(max_threads): thr = Thread(target=consumer) thr.start() dirlist.join() The strange behavior I'm getting is that if a thread encounters a file that's already been processed, the thread stalls out and waits until the entire program ends. I've done a little bit of testing, and the first 7 threads (assuming 8 is the max) stop, while the 8th thread keeps processing, one file at a time. But, by doing that, I'm losing the entire reason for threading the application. Am I doing something wrong, or is this the expected behavior of the Queue/threading classes in Python 2.6?

  • YouTube API, jQuery attr won't swap element attributes (I think) in IE, but works in FF

    - by Anthony
    JavaScript (jQuery) function display_youtube(new_url) { $('#movie_url').removeAttr('value'); $('#embed_url').removeAttr('src'); $(document).ready(function() { $('#movie_url').attr('value', new_url); $('#embed_url').attr('src', new_url); $('#shade').css('display', 'block'); $('#youtube_player').css('display', 'block'); $('#exit_youtube').css('display', 'block'); }); } HTML <object width="720" height="480"> <param id="movie_url" name="movie" value="http://www.youtube.com/v/_eaToCSn7yU?f=user_uploads&app=youtube_gdata&autoplay=0" /> <param name="allowFullScreen" value="true" /> <param name="allowscriptaccess" value="always" /> <embed id="embed_url" src="http://www.youtube.com/v/_eaToCSn7yU?f=user_uploads&app=youtube_gdata&autoplay=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="720" height="480" /> </object> Hyperlink <a href="javascript:display_youtube('http://www.youtube.com/v/_eaToCSn7yU?f=user_uploads&app=youtube_gdata&autoplay=1');">Click Here for Fun!</a> What I've done is parsed YouTube's API for the videos on my user channel. The hyperlink above is php generated, meant to trigger the above JavaScript function, and swap the url from attributes contained in ids "movie_url" and "embed_url". Works just like it should in FF, but IE will only perform the .css commands. My guess? IE doesn't like me assigning IDs to PARAM and EMBED, perhaps? What do you think?

  • Setting up isolated COM for multiple projects.

    - by Praneeth
    My solution consists of multiple projects all of which out type class library except one whose output type is windows application. The application references all the other projects. I also have a COM component which is referenced by some of the projects and the application also. I can setup the regfree COM by changing the Isolated property of the referenced COM component in visual studio to TRUE. The solution builds successfully and I can see the manifest file generated for that particular assembly or application. Now, my question is that do I need to do this for all the projects which reference the COM component? If yes, then I know that i cannot set the Isolated property to TRUE on more than one project(gives a build error) so how do I workaround this? I am relatively new to .net and don't know much regfree COM(i assume what i am doing IS regfree COM?). Any help I can get on this issue is greatly appreciated. Thanks. I am currently using VS 2008.

  • is it possible to write a program which prints its own source code utilizing a "sequence-generating-

    - by guest
    is it possible to write a program which prints its own source code utilizing a "sequence-generating-function"? what i call a sequence-generating-function is simply a function which returns a value out of a specific interval (i.e. printable ascii-charecters (32-126)). the point now is, that this generated sequence should be the programs own source-code. as you see, implementing a function which returns an arbitrary sequence is really trivial, but since the returned sequence must contain the implementation of the function itself it is a highly non-trivial task. this is how such a program (and its corresponding output) could look like #include <stdio.h> int fun(int x) { ins1; ins2; ins3; . . . return y; } int main(void) { int i; for ( i=0; i<size of the program; i++ ) { printf("%c", fun(i)); } return 0; } i personally think it is not possible, but since i don't know very much about the underlying matter i posted my thoughts here. i'm really looking forward to hear some opinions!

  • WSDL first for existing service layer

    - by Jurgen H
    I am working on an existing Java project with a typical services - dao setup for which only a webapplication was available. My job is to add webservices on top of the services layer, but the webservices have their own functional analysis and datamodel. The functional analyses ofcource focuses on what is possible in the different service methods. As good practice demands, we used the WSDL first strategy and generated JAXB bound Java classes and a SEI for the webservices. After having implemented the webservices partially, we noticed a 70% match between the datamodel. This resulted in writing converters which take the webservice JAXB classes and map them with the service layer classes. Customer customer = new Customer(); customer.setName(wsCustomer.getName()); customer.setFirstName(wsCustomer.getFirstName(); .. This is a very obvious example, some other mappings where little more complicated. Can anyone give his best practices, experiences, solutions to this kind of situations? Are any of these frameworks usefull? http://transmorph.sourceforge.net/wiki/index.php/Main_Page http://ezmorph.sourceforge.net/ Please don't start a discussion about WSDL first vs code first.

  • What should I do with an over-bloated select-box/drop-down

    - by Tristan Havelick
    All web developers run into this problem when the amount of data in their project grows, and I have yet to see a definitive, intuitive best practice for solving it. When you start a project, you often create forms with tags to help pick related objects for one-to-many relationships. For instance, I might have a system with Neighbors and each Neighbor belongs to a Neighborhood. In version 1 of the application I create an edit user form that has a drop down for selecting users, that simply lists the 5 possible neighborhoods in my geographically limited application. In the beginning, this works great. So long as I have maybe 100 records or less, my select box will load quickly, and be fairly easy to use. However, lets say my application takes off and goes national. Instead of 5 neighborhoods I have 10,000. Suddenly my little drop-down takes forever to load, and once it loads, its hard to find your neighborhood in the massive alphabetically sorted list. Now, in this particular situation, having hierarchical data, and letting users drill down using several dynamically generated drop downs would probably work okay. However, what is the best solution when the objects/records being selected are not hierarchical in nature? In the past, of done this with a popup with a search box, and a list, but this seems clunky and dated. In today's web 2.0 world, what is a good way to find one object amongst many for ones forms? I've considered using an Ajaxifed search box, but this seems to work best for free text, and falls apart a little when the data to be saved is just a reference to another object or record. Feel free to cite specific libraries with generic solutions to this problem, or simply share what you have done in your projects in a more general way

  • How can I embed images within my application and use them in HTML control?

    - by Atara
    Is there any way I can embed the images within my exe (as resource?) and use it in generated HTML ? Here are the requirements: A. I want to show dynamic HTML content (e.g. using webBrowser control, VS 2008, VB .Net, winForm desktop application) B. I want to generate the HTML on-the-fly using XML and XSL (file1.xml or file2.xml transformed by my.xsl) C. The HTML may contain IMG tags (file1.gif and or file2.gif according to the xml+xsl transformation) and here comes the complicated one: D. All these files (file1.xml, file2.xml, my.xsl, file1.gif, file2.gif) should be embedded in one exe file. I guess the XML and XSL can be embedded resources, and I can read them as stream, but what ways do I have to reference the image within the HTML ? <IMG src="???" /> I do not want to use absolute path and external files. If the image files are resources, can I use relative path? Relative to what? (I can use BASE tag, and then what?) Can I use stream as in email messages? If so, where can I find the format I need to use? http://www.websiteoptimization.com/speed/tweak/inline-images/ are browser dependent. What is the browser used by webBrowser control? IE? what version? Does it matter if I use GIF or JPG or BMP (or any other image format) for the images? Does it matter if I use mshtml library and not the regular webBrowser control? (currently I use http://www.itwriting.com/htmleditor/index.php ) Does it matter if I upgrade to VS 2010 ? Thanks, Atara

  • transmit a java.lang.reflect.Proxy over a network

    - by panzi
    Is there a convenient way to transmit an object including its code (the class) over a network (not just the instance data)? Don't ask me why I want to do this. It's in an assignment. I asked several times if that is really what they meant and the didn't rephrase their answer so I guess they really want us to transmit code (not just the field data) over a network. To be honest I have no clue why we need a Proxy in this assignment anyway, just writing a simple class would do IMO. The assignment says that we should instantiate the proxy on the server and transmit it to the client (and yes, they talk about a java.lang.reflect.Proxy, they name this class). Because there is no class file for a proxy I can't deploy that. I guess I would have to somehow read out the bytecode of the generated Proxy, transmit it to the client and then load it. Which makes absolutely no sense at all, but this seems what they want us to do. I don't get why.

  • Storing a jpa entity where only the timestamp changes results in updates rather than inserts (desire

    - by David Schlenk
    I have a JPA entity that stores a fk id, a boolean and a timestamp: @Entity public class ChannelInUse implements Serializable { @Id @GeneratedValue private Long id; @ManyToOne @JoinColumn(nullable = false) private Channel channel; private boolean inUse = false; @Temporal(TemporalType.TIMESTAMP) private Date inUseAt = new Date(); ... } I want every new instance of this entity to result in a new row in the table. For whatever reason no matter what I do it always results in the row getting updated with a new timestamp value rather than creating a new row. Even tried to just use a native query to run an insert but channel's ID wasn't populated yet so I gave up on that. I've tried using an embedded id class consisting of channel.getId and inUseAt. My equals and hashcode for are: public boolean equals(Object obj){ if(this == obj) return true; if(!(obj instanceof ChannelInUse)) return false; ChannelInUse ciu = (ChannelInUse) obj; return ( (this.inUseAt == null ? ciu.inUseAt == null : this.inUseAt.equals(ciu.inUseAt)) && (this.inUse == ciu.inUse) && (this.channel == null ? ciu.channel == null : this.channel.equals(ciu.channel)) ); } /** * hashcode generated from at, channel and inUse properties. */ public int hashCode(){ int hash = 1; hash = hash * 31 + (this.inUseAt == null ? 0 : this.inUseAt.hashCode()); hash = hash * 31 + (this.channel == null ? 0 : this.channel.hashCode()); if(inUse) hash = hash * 31 + 1; else hash = hash * 31 + 0; return hash; } } I've tried using hibernate's Entity annotation with mutable=false. I'm probably just not understanding what makes an entity unique or something. Hit the google pretty hard but can't figure this one out.

  • PHP IIS problems downloading file says it is corrupt

    - by Matt
    Hi, I am running PHP on IIS 6 with mssql. I have uploaded a file to my webserver through a php script. Upon checking the file on the server the file is ok and not corrupt. However, when i then have a link on my website to try and download the file, it says the file is corrupt. I know the file isnt corrupt as i can view it perfectly if i look at the file on the server. Is seems like this is a common problem as a similar problem was posted here: http://www.bigresource.com/Tracker/Track-php-1pAakBhT/ Any help would be much appreciated. Thanks, M My download code is as follows: $filesize = $rows->filesize; $filepath = $rows->filepath; header("Content-Disposition: attachment; filename=$filename"); header("Content-length: $filesize"); header("Content-type: application/pdf"); header("Cache-control: must-revalidate"); header("Content-Description: PHP Generated Data"); readfile($filepath);

  • How do you lock down & secure files stored on server in ASP.NET?

    - by Jon
    How do I go about securing files that are stored on the server? We have an ASP.NET app which generates PDFs. These are not stored in the wwwroot folder but in another folder i.e. C:\inetpub\data. This provides more security but maybe not enough. The ASP.NET/IIS process will need write access to this folder so it generate the PDFs there. Once the pdf is generated, it can be viewed using an ASP.NET form called viewpdf.aspx with the file to be viewed add to the query string like so viewpdf.aspx?FILE=mynewfile.pdf. This is loaded from a gridview. The full path to C:\inetpub\data is resolved and loaded in the Page_load event of the viewer page. Now I'm wondering how to secure this. Anybody could just view the file. Not by entering in the URL, as it won't been seen by IIS (its not in wwwroot), but could change the querystring in the viewpdf page. How do I stop anybody hacking this?

  • N Tiers with SubSonic 3, Dirty Columns collection is alwayes empty on update

    - by Adel
    Hello guys here is what i am doing, and not working for me. I have a DAL generated with SubSonic 3 ActiveRecord template, i have a service layer (business layer if you well) that have mixture of facade and some validation. say i have a method on the Service layer like public void UpdateClient(Client client); in my GUI i create a Client object fill it with some data with ID and pass it to the service method and this never worked, the dirty columns collection (that track which columns are altered in order to use more efficant update statment) is alwayes empty. if i tried to get the object from database inside my GUI then pass it to the service method it's not working either. the only scenario i find working is if i query the object from the database and call Update() on the same context all inside my GUI and this defeats the whole service layer i've created. however for insert and delete everything working fine, i wonder if this have to do something with object tracking but what i know is SubSonic don't do that. please advice. thanks. Adel.

  • genStrAsCharArray optimisation benefits

    - by Rich
    Hi I am looking into the options available to me for optimising the performance of JBoss 5.1.0. One of the options I am looking at is setting genStrAsCharArray to true in <JBOSS_HOME>/server/<PROFILE>/deployers/jbossweb.deployer/web.xml. This affects the generation of .java code from .JSPs. The comment describes this flag as: Should text strings be generated as char arrays, to improve performance in some cases? I have a few questions about this. Is this the generation of Strings in the dynamic parts of the JSP page (ie each time the page is called) or is it the generation of Strings in the static parts (ie when the .java is built from the JSP)? "in some cases" - which cases are these? What are the situations where the performance is worse? Does this speed up the generation of the .java, the compilation of the .class or the execution of the .class? At a more technical level (and the answer to this will probably depend on the answer to part 1), why can the use of char arrays improve performance? Thanks in advance Rich

  • Formatting data for printing automatically

    - by 0bytes
    I have a requirement to retrieve data, format it to mimic an old request format we've used for years and then send it via IP address to any of a number of printers. Gathering the data and selecting the printer is no problem. I need to format the output for the printer and I'm just not sure what's best. The requirement is that the end users not have any interaction with the print request that's generated; only the intended recipients of the request job will know of the printed (& in a future release e-mailed) request. We also a requirement for a future update that we will have to incorporate into this solution an option to change the config in the DB so that each recipient site can choose printing or e-mail notification so I expect that I'll need to keep the control in a console app or webservice. I have the data and I can send it to the printers or generate an HTML-formatted e-mail easily; I just need to format it for the autoprinting. I don't think SSRS will help because I don't know of a way to designate a printer when running a report. Thanks for all help & suggestions.
