  • Servlets: forwarding to a resource in a different webapp

    - by skaffman
    I'm trying to construct a java web app along modular principles, with some common resources (JSPs, mainly) in one WAR, and some custom resources in another. This means JSPs scattered across different WARs. Now JavaEE frowns upon this sort of shenanigans, and wants you to put everything in one place. My current workaround to this is to have an Eclipse-triggered Ant script which copies the content of one WAR into the other, but this is not a pleasant solution (it's fragile and too IDE-dependent). Ideally, what I'd like to be able to do is for a servlet to forward to a JSP located in a different WAR to one in which it is itself deployed. This would allow greater freedom in how I assemble my WARs. However, the RequestDispatcher does not seem to support such things. Another possibility is to use <c:import>, which does allow resources to be imported from a different WAR (with some caveats). This would probably allow me to have a "hook" JSP in one WAR, which then drags in the required JSP from another. This is a bit clunky, though, and the fact that <c:import> permits it shows that the underlying servlet API does also. But how do I access that functionality via the RequestDispatcher in a servlet?

  • JSON-P and a GET resource?

    - by user246114
    Hi, If a website operating on a domain other than my own supports get requests, like: http://api.someothersite.com/v1/farms There's no way for me to access it using JSON-P right, they would have to have support for it as a query parameter? Something like: http://api.someothersite.com/v1/farms?callback=fantastic I mean, there's no way for me to use it without them explicitly supporting it, right? Thanks

  • Looking for a good course/book/resource on modern databases

    - by spanky
    This is slightly embarrassing. I'm a professional developer working at one of the big tech companies and I've never used a database. I've got an idea for a website I want to build as a learning experience and possibly as a business, but I don't have the faintest idea what database to use, let alone how to fix/debug the database when I run into problems. I'm looking for a course, a website, a book, etc., that will give me an overview of modern database technology (SQL vs. NOSQL vs. relational vs. non-relational (I only have a vague idea what these even mean)). I'm starting by googling/wikipediaing all of these terms, but if there are better, comprehensive resources available that I should be aware of, I'd love to hear about them.

  • Referencing java resource files for cold fusion

    - by Chimeara
    I am using a .Jar file containing a .properties file in my CF code, however it seems unable to find the .properties file when run from CF. My java code is: String key =""; String value =""; try { File file = new File("src/test.properties"); FileInputStream fileInput = new FileInputStream(file); Properties properties = new Properties(); properties.load(fileInput); fileInput.close(); Enumeration enuKeys = properties.keys(); while (enuKeys.hasMoreElements()) { key = (String) enuKeys.nextElement(); value = properties.getProperty(key); //System.out.println(key + ": " + value); } } catch (FileNotFoundException e) { e.printStackTrace(); key ="error"; } catch (IOException e) { e.printStackTrace(); key ="error"; } return(key + ": " + value); I have my test.properties file in the project src folder, and make sure it is selected when compiling, when run from eclipse it gives the expected key and value, however when run from CF I get the caught errors. My CF code is simply: propTest = CreateObject("java","package.class"); testResults = propTest.main2(); Is there a special way to reference the .properties file so CF can access it, or do I need to include the file outside the .jar somewhere?

  • Android: Referring to a string resource when defining a log name

    - by spookypeanut
    In my Android app, I want to use a single variable for the log name in multiple files. At the moment, I'm specifying it separately in each file, e.g. public final String LOG_NAME = "LogName"; Log.d(LOG_NAME, "Logged output); I've tried this: public final String LOG_NAME = (String) getText(R.string.app_name_nospaces); And while this works in generally most of my files, Eclipse complains about one of them: The method getText(int) is undefined for the type DatabaseManager I've made sure I'm definitely importing android.content.Context in that file. If I tell it exactly where to find getText: Multiple markers at this line - Cannot make a static reference to the non-static method getText(int) from the type Context - The method getText(int) is undefined for the type DatabaseManager I'm sure I've committed a glaringly obvious n00b error, but I just can't see it! Thanks for all help: if any other code snippets would help, let me know.

  • Include HTML file as embedded resource

    - by Stacey
    A followup to another question I did, I've done some more digging but I am still coming up dry. Is there any way to include .HTML/.ASPX files as 'embedded resources' into an ASP.NET MVC application? I've found lots of examples of using string resources, but never other files entirely.

  • mysql_num_rows(): supplied argument is not a valid MySQL result resource

    - by php-b-grader
    I am getting this error when I pass an invalid SQL string... I spent the last hour trying to find the problem assuming - It's not my SQL it must be the db handle... ANyway, I've now figured out that it was bad SQL... What I want to do is test the result of the mysql_query() for a valid resultset. I am simply using empty($result)... Is this the most effective test? Is there a more widely accepted method of testing a resultset for a valid result?

  • vs2008 resource editor changes rc file language

    - by user346134
    Hi all, I am doing some improvements to an application in vs2008 in c++. When i try to edit resources (for example add an entry in the string table), the vs2008 editor changes the rc file language from LANG_ENGLISH to LANG_NEUTRAL and a non english text is replaced with question marks. If i edit the rc file externally (in notepad), and then load it to the vs2008 it works fine. can anybody help me solve this? thanks Shimon

  • Generic DRM (Distributed resource management) wrapper

    - by Pavel Bernshtam
    I need to write a software, which launches DRM jobs in a customer environment and monitors those jobs status. It should work with various customer environments and DRMs - like LSF, Sun Grid and others. Can you recommend some 3rd party library, which hides DRM differences from me and has API like "launch job", "get list of jobs", "get job status" etc. ? Both Java and native libraries are good for me.

  • best practice for Jquery plugin implementation and resource locations

    - by ptutt
    This is probably a very basic question, but I seem to have issues plugging in jquery plug-ins. The issue seems to be around the location of the script, css and images and ensuring the css has the correct url to the images. The standard plug-in has the following folder structure (eg : JPicker) js css images My project is asp.net mvc so I have the default: scripts images content So, I try to split the jquery plugin to the appropriate folders (not sure if this is the best way?). Then I try to correct the references to images (background urls) in the css. I believe the url is relative to the page that is implementing the css file, not the location of the css file itself. Anyway, when I try the above, the plugins don't seem to work. I believe the issue lies with the images not being found. The jquery code runs without errors, so I assume that's not the problem. Any help/advice much appreciated

  • Resource id #45 [on hold]

    - by user2916506
    What is this error? I am trying to connect from PHP to Traffic Live mysql and do a POST and at some id's I get this error. With the biggest part of contacts my code works just fine but it keeps getting this trouble maker. What can I do? Here is the trouble making code:if ($sales_datemodified[$h] $traffic_datemodified[$t]) { //if ($traffic_id[$t] != 22033) { $postrequestclient = $clients - post("staff/employee", null, '{"@class": "com.sohnar.trafficlite.transfer.trafficcompany.TrafficEmployeeTO", "id": ' . $traffic_id[$t] . ',"locationId":' . $traffic_locationid[$t] . ', "departmentId": ' . $traffic_departmentid[$t] . ', "ownerCompanyId": ' . $traffic_ownercompanyid[$t] . ',"userId": ' . $traffic_userid[$t] . ',"userName": "' . $traffic_username[$t] . '","employeeDetails": {"id": ' . $traffic_id[$t] . ',"jobTitle": "' . $sales_title[$h] . '","costPerHour": { "amountString": ' . $traffic_amountString[$t] .

'" }}}') - setAuth(user, password); $postresponseclient = $postrequestclient - send() - json(); I don't have any errors in my code. That commented "if" is for excluding the trouble making contact on which I get this error. If I uncomment that the program runs fine without any problems. The problem is that this test is made on a small number of contacts and if I add more contacts to the test I get more errors of this kind. this should be a synchronization job so excluding all the "bad" contacts won't work

  • Spring Webflow in Grails keeping plenty of hibernate sessions open

    - by Pavel P
    Hi, I have an Internet app running on Grails 1.1.2 and it integrates Spring WebFlow mechanism. The problem is that there are some bots ignoring robots.txt and are entering the flow quite often. Because second step of the flow needs some human intelligence, the bot leaves open flow after the first step. This causes a lot of open flows which leades to a lot of abandoned open hibernate sessions. Do you know some common clean-up mechanism for this kind of unattended flows (plus hibernate sessions) in Grails+Spring WebFlow? Thanks, Pavel

  • Code Formatter: cleaning up horribly formatted jsp code

    - by ahiru
    So I am working on a jsp/servlet that came to me and I'm looking at the jsp file and it is just a jungle of jstl tags, java code and html thrown together. At first it looked like someone ran the standard eclipse formatter on it and had the page width set to 40 so alot of stuff is broken up, I tried to format it with a larger page width but that seemed to make it worse to the point of not being able to tell what is going on without formatting parts of it first. Anyone have any luck with any jsp/code formatter?

  • Do I need to explicitly destroy JavaScript objects on window unload?

    - by Bilal Aslam
    I have a JavaScript widget that is hosted on websites. This widget tracks state in a number of variables in its local namespace. Moreover, it attaches listeners for several events, such as mouse movement. Should I explicitly destroy both state-tracking variables and detach event listeners on window unload? Or is it ok to rely on the browser to do a good job of cleaning up after the user leaves the page that hosts my widget?

  • Shutting down a windows service that has threads

    - by Dave
    I have a windows service written in .NET 3.5 (c#) with a System.Threading.Timer that spawns several Threads in each callback. These are just normal threads (no Thread Pool) and I've set the IsBackground = true on each thread since I'm only going to be running managed code. When a user stops the service, what happens to all the threads? Do they die gracefully? I don't have any code that manages the threads via calling join or abort. Is it correct to assume the IsBackground = true is enough to assume the threads will be disposed and stopped when a user stops the service? What exactly happens when someone stops a windows service via the Service Manager GUI? Does it kill the process after it fires the OnStop event? This would actually be acceptable for me because I've built a separate mechanism that allows a user know for sure there are no threads before they stop the service. This is done via 2 WCF methods exposed from a ServiceHost that runs inside the Windows Service. There's one method to stop spawning new threads and another method to query how many running threads there are left. I'm just curious what happens if they skip those steps and just stop the service... It seems the IsBackground helps achieve this:

  • Efficient way to copy a collection of Nodes, treat them, and then serialize?

    - by Danjah
    Hi all, I initially thought a regex to remove YUI3 classNames (or whole class attributes) and id attributes from a serialized DOM string was a sound enough approach - but now I'm not sure, given various warnings about using regex on HTML. I'm toying with the idea of making a copy of the DOM structure in question, performing: var nodeStructure = Y.one('#wrap').all('*'); // A YUI3 NodeList // Remove unwanted classNames.. I'd need to maintain a list of them to remove :/ nodeStructure.removeClass('unwantedClassName'); and then: // I believe this can be done on a NodeList collection... nodeStructure.removeAttribute('id'); I'm not quite sure about what I'd need to do to 'copy' a collection of Nodes anyway, as I don't actually want to do the above to my living markup, as its only being saved - not 'closed' or 'exited', a user could continue to change the markup, and then save again. The above doesn't make a copy, I know. Is this efficient? Is there a better way to 'sanitize' my live markup of framework additions to the DOM (and maybe other things too at a later point), before saving it as a string? If it is a good approach, what's a safe way to go about copying my collection of Nodes for safe cleaning? Thanks! d

  • How to make this C++ code more DRY?

    - by Macha
    I have these two methods on a class that differ only in one method call. Obviously, this is very un-DRY, especially as both use the same formula. int PlayerCharacter::getAttack() { attack = 1 + this.level; for(int i = 0; i <= current_equipment; i++) { attack += this.equipment[i].getAttack(); } attack *= sqrt(this.level); return attack; } int PlayerCharacter::getDefense() { defense = 1 + this.level; for(int i = 0; i <= current_equipment; i++) { defense += this.equipment[i].getDefense(); } defense *= sqrt(this.level); return defense; } How can I tidy this up in C++?
