• SQL Server Express performance issue

  - by Developer IT

  Hi folks ! I know my questions will sound silly and probably nobody will have perfect answer but since I am in a complete dead-end with the situation it will make me feel better to post it here. So... I have a SQL Server Express database that's 500 Mb. It contains 5 tables and maybe 30 stored procedure. This database is use to store articles and is use for the Developer It web site. Normally the web pages load quickly, let's say 2 ou 3 sec. BUT, sqlserver process uses 100% of the processor for those 2 or 3 sec. I try to find which stored procedure was the problem and I could not find one. It seems like every read into the table dans contains the articles (there are about 155,000 of them and 20 or so gets added every 15 minutes). I added few index but without luck... It is because the table is full text indexed ? Should I have order with the primary key instead of date ? I never had any problems with ordering by dates.... Should I use dynamic SQL ? Should I add the primary key into the url of the articles ? Should I use mutiple indexes for seperate columns or one big index ? I you want more details or code bits, just ask for it. Basicly, every little hint is much apreciated. Thanks.

• why MVC instead of good old asp.net? Still not grasping why I should go this route??

  - by RJ

  I know this question has been asked before and I read all the answers but they still don't give me the answers I am looking for. I need something concrete. I volunteered to give a presentation on MVC to other developers in our group which forces me to learn it. The big question everyone has is: "What can MVC bring to the table that we can't do in asp.net or MVC can do faster. I have just gone through Nerd Dinner and actually created a complete website that sort of mimics Nerd Dinner. But as great a job that Scott Guthrie did on it, there are big gaps that aren't answered such as, how do I throw a textbox on the listing page with a button and do a simple search. In asp.net, I would throw a textbox, button and grid on the page and bind it to a sproc and away I go. What is the equivalent in MVC. I guess I need a really good tutorial on how to use MVC without using Linq-to-Sql. I know I am sort of babbling on about this but it is a very serious question that still seems to go unanswered. On a side note, the View page of MVC brings back nightmares of classic asp with all the in-line code that we got away from way back when with code behind pages. Yes, MVC has Controller and Model classes which are great but I still don't like the classic asp tags in the html. Help me out here, I really like the concept of MVC and want it to be successful but I need more!

• Visual Studio 2008 Setup Project - Include .NET Framework 3.5

  - by rajadiga

  I built a Visual Studio 2008 setup Project wich depends on .NET 3.5. I added Prerequisites like: .NET 3.5, Microsoft office interoperability, VS tools for office System 3.0 Run time, .etc. After that Selected "Download Prerequisite from Same location as my application" in Specify install location for Prerequisite. I Built the setup and found mysetup.msi in Release directory. In a new machine I started fresh installation of my application. A dialog shows like this "This Setup Requires .NET framework 3.5 , Please install .NET setup then run this setup, .NET Framework can be obtained from web Do you want to do that now?" it gives "Yes" and "No" option - if I press yes it goes to Microsoft website. How can avoid it? I wanted setup take .NET Framework to be installed from same location where I put all setup files including mysetup.msi? In case of quiet installation cmd /c "msiexec /package mysetup.msi /quiet /log install.log" ..in log I can see only half way through installation then error Property(S): HideFatalErrorForm = TRUE MSI (s) (D0:24) [00:07:08:015]: Product: my product-- Installation failed. === Logging stopped: 3/23/2010 0:07:08 === How can complete I the installation without user intervention and without error using VS2008 setup project?

• Perl Module from relative path not working in IIS6

  - by Laramie

  Disclaimer: I am not a PERL developer and am learning by the seat of my pants. I am using a Perl module called from a CGI scipt in IIS 6 that is bombing. The identical folder structure on an XP machine (IIS 5.1) works fantastic. If I remove the module loading command at line 9, it will print "about to load" and "ok", but When I try to run use Language::Guess; I receive The specified CGI application misbehaved by not returning a complete set of HTTP headers. in the browser. The folder structure is /cgi-bin/test.pl /PerlModules/Language/Guess.pm I have tried adjusting the file/folder permissions and have reviewed my IIS configuration time and again. It runs fine from the command line on the IIS machine or if I copy the module into \Perl\site\lib, but I don't have permission to load modules on the shared server this script is destined for. Am I missing something simple? Here is test.pl use strict; use CGI ':standard'; print header("text/html"); use lib "..\\PerlModules\\"; print "about to load<br/>"; #bombs here use Language::Guess; print "ok"

• How to disable firefox's form auto completion without change events?

  - by Dmitriy Likhten

  So firefox has a nifty mechanism which will try to autocomplete values in fields when a page is reloaded or the back button is used. Which is great and all except when you have something like a drop-down which when set to a value modifies the page using ajax. What winds up happening is that the browser reloads the page, the drop down is pre-filled with the remembered value, and then no change event is fired when the dom is ready. And therefore the change handlers attached don't fire and thus the page does not update. Is there a good way to "fix" this behavior so that it works for the user as expected: a) We do want the browser to auto-complete because that is a good user experience. b) Still want that onchange event firing. The only thing I can think of doing at the moment is to add an on-ready event to the document which has javascript pre-populated with initial values in the form, when the document loads the javascript will check the pre-populated values and if not matching what is in the input will trigger the change handlers. Anyone have a better solution? Is there a lib that does this already? (Using Rails 2.3.5 + jQuery)

• Is it wise to use temporary tables?

  - by Industrial

  Hi guys, We have a mySQL database table for products. We are utilizing a cache layer to reduce database load, but we think that it's a good idea to minimize the actual data needed to be stored in the cache layer to speed up the application further. All the products in the database, that is visible to visitors have a price attached to them: The prices are stored in a different table, called prices . There are multiple price categories depending on which discount level each visitor (customer) applies to. From time to time, there are campaigns which means that a special price for each product is available. The special prices are stored in a table called specials. Is it a bad to make a temp table that binds the tables together? It would only have the neccessary information and would ofcourse be cached. -------------|-------------|------------ | productId | hasPrice | hasSpecial -------------|-------------|------------ 1 | 1 | 0 2 | 1 | 1 By doing such, it would be super easy to know if the specific product really has a price, without having to iterate through the complete prices or specials table each time a product should be listed or presented. Are temp tables a common thing for web applications or is it just bad design?

• I am confused -- Will this code always work?

  - by Shekhar

  Hello, I have written this piece of code public class Test{ public static void main(String[] args) { List<Integer> list = new ArrayList<Integer>(); for(int i = 1;i<= 4;i++){ new Thread(new TestTask(i, list)).start(); } while(list.size() != 4){ // this while loop required so that all threads complete their work } System.out.println("List "+list); } } class TestTask implements Runnable{ private int sequence; private List<Integer> list; public TestTask(int sequence, List<Integer> list) { this.sequence = sequence; this.list = list; } @Override public void run() { list.add(sequence); } } This code works and prints all the four elements of list on my machine. My question is that will this code always work. I think there might be a issue in this code when two/or more threads add element to this list at the same point. In that case it while loop will never end and code will fail. Can anybody suggest a better way to do this? I am not very good at multithreading and don't know which concurrent collection i can use? Thanks Shekhar

• Dev-C++ and Detours compiling error

• Atomically maintaining a counter using Sub-sonic ActiveRecord

  - by cantabilesoftware

  I'm trying to figure out the correct way to atomically increment a counter in one table and use that incremented value as an pseudo display-only ID for a record in another. What I have is a companies table and a jobs table. I want each company to have it's own set of job_numbers. I do have an auto increment job_id, but those numbers are shared across all companies. ie: the job numbers should generally increment without gaps for each company. ie: companies(company_id, next_job_number) jobs(company_id, job_id, job_number) Currently I'm doing this (as a method on the partial job class): public void SaveJob() { using (var scope = new System.Transactions.TransactionScope()) { if (job_id == 0) { _db.Update<company>() .SetExpression("next_job_number").EqualTo("next_job_number+1") .Where<company>(x => x.company_id == company_id) .Execute(); company c = _db.companies.SingleOrDefault(x => x.company_id == company_id); job_number = c.next_job_number; } // Save the job this.Save(); scope.Complete(); } } It seems to work, but I'm not sure if there are pitfalls here? It just feels wrong, but I'm not sure how else to do it. Any advice appreciated.

• Showing an array of certain pages with WP_Query in Wordpress

  - by Ragnar

  What I'm trying to achieve is showing only certain pages in a loop. 3 certain pages, not more, not less. I've tried many things but I just can't complete it. <?php $special_tabs = new WP_Query(array('post_type' => 'page', 'post_in' => array(100,102,104))); ?> What this does, from what I understand, is that it shows an array of pages and then includes those ID's there as well. <?php $special_tabs = new WP_Query(array ('page_id' => 100)); ?> And this shows only ONE certain page, it doesn't support the showing of array of different IDs. I'm sure I am not the first person to have such specific needs and I'm certain there is a relatively simple way to achieve what I'm trying to achieve, but I just can't come up with a solution or to find one. Can anybody please help me with this? Many thanks in advance!

• JQuery Progress Bar Inline Text

  - by Craig

  Hello, I am trying to use the basic progress bar however I am unable to figure out the css/command to actually put some text inside the bar. I am using this progress bar: http://docs.jquery.com/UI/Progressbar however I am open to other ones if they are just as simple to implement. I want it to display in the left corner some static information and then a percentage of complete somewhere in the right section. All css I attempted to do just made the information display below or to the side of. As well I am unsure how to actually have this CSS change based on a JQuery method (new to JQuery). below is my actual JQuery. Don't try to understand the url value just assume it returns 0-100. <script type="text/javascript"> var url = "%%$protocol_url%%/bin/task_status?id=%%$tid%%&cmd=percent_done"; $(function() { var progress = 0; //alert("some value" + value, value); $("#progressbar").progressbar({ progress: 0 }); setTimeout(updateProgress, 500); }); function updateProgress() { var progress; $.get(url, function(data) { // data contains whatever that page returns if (data < 100) { $("#progressbar") .progressbar("option", "value", data); setTimeout(updateProgress, 500); } else { $("#progressbar") .progressbar("option", "value", 100); } }); } Thanks

• How to append to a log file in powershell?

  - by Mark Allison

  Hi there, I am doing some parallel SQL Server 2005 database restores in powershell. The way I have done it is to use cmd.exe and start so that powershell doesn't wait for it to complete. What I need to do is to pipe the output into a log file with append. If I use Add-Content, then powershell waits, which is not what I want. My code snippet is foreach ($line in $database_list) { <snip> # Create logins sqlcmd.exe -S $instance -E -d master -i $loginsFile -o $logFile # Read commands from a temp file and execute them in parallel with sqlcmd.exe cmd.exe /c start "Restoring $database" /D"$pwd" sqlcmd.exe -S $instance -E -d master -i $tempSQLFile -t 0 -o $logFile [void]$logFiles.Add($logFile) } The problem is that sqlcmd.exe -o overwrites. I've tried doing this to append: cmd.exe /c start "Restoring $database" /D"$pwd" sqlcmd.exe -S $instance -E -d master -i $tempSQLFile -t 0 >> $logFile But it doesn't work because the output stays in the SQLCMD window and doesn't go to the file. Any suggestions? Thanks, Mark.

• Verify an event was raised by mocked object

  - by joblot

  In my unit test how can I verify that an event is raised by the mocked object. I have a View(UI) -- ViewModel -- DataProvider -- ServiceProxy. ServiceProxy makes async call to serivce operation. When async operation is complete a method on DataProvider is called (callback method is passed as a method parameter). The callback method then raise and event which ViewModel is listening to. For ViewModel test I mock DataProvider and verify that handler exists for event raised by DataProvider. When testing DataProvider I mock ServiceProxy, but how can I test that callback method is called and event is raised. I am using RhinoMock 3.5 and AAA syntax Thanks -- DataProvider -- public partial class DataProvider { public event EventHandler<EntityEventArgs<ProductDefinition>> GetProductDefinitionCompleted; public void GetProductDefinition() { var service = IoC.Resolve<IServiceProxy>(); service.GetProductDefinitionAsync(GetProductDefinitionAsyncCallback); } private void GetProductDefinitionAsyncCallback(ProductDefinition productDefinition, ServiceError error) { OnGetProductDefinitionCompleted(this, new EntityEventArgs<ProductDefinition>(productDefinition, error)); } protected void OnGetProductDefinitionCompleted(object sender, EntityEventArgs<ProductDefinition> e) { if (GetProductDefinitionCompleted != null) GetProductDefinitionCompleted(sender, e); } } -- ServiceProxy -- public class ServiceProxy : ClientBase<IService>, IServiceProxy { public void GetProductDefinitionAsync(Action<ProductDefinition, ServiceError> callback) { Channel.BeginGetProductDefinition(EndGetProductDefinition, callback); } private void EndGetProductDefinition(IAsyncResult result) { Action<ProductDefinition, ServiceError> callback = result.AsyncState as Action<ProductDefinition, ServiceError>; ServiceError error; ProductDefinition results = Channel.EndGetProductDefinition(out error, result); if (callback != null) callback(results, error); } }

• How to determine the size of a project (lines of code, function points, other)

  - by sixtyfootersdude

  How would you evaluate project size? Part A: Before you start a project. Part B: For a complete project. I am interested in comparing unrelated projects. Here are some options: 1) Lines of code. I know that this is not a good metric of productivity but is this a reasonable measure of project size? If I wanted to estimate how long it would take to recreate a project would this be a reasonable way to do it? How many lines of code should I estimate a day? 2) Function Points. Functions points are defined as the number of: inputs outputs inquires internal files external interfaces Anyone have a veiw point on whether this is a good measure? Is there a way to **actually do this? Does anyone have another solution? Hours taken seems like it could be a useful metric but not solely. If I ask you what is a "bigger program" and give you two programs how would you approach the question? I have seen several discussions of this on stackover flow but most discuss how to measure programmer productivity. I am more interested in project size.

• Displaying data from a linked table and displaying it as a list with HTML/PHP/MySQL

  - by user1672694

  I have three tables. students studentID | FirstName | LastName | Email | Form course CCode | Title courseenrolement courseenrolementid | studentID | ccode | complete | scode With the website, I have a page where I can view all the current enrolements and I wish to be able to view the list displaying the first name, surname and course title. I know I could do it with the following SQL (for the names): SELECT FirstName, LastName FROM student, courseenrolement WHERE courseenrolement.studentID = student.studentID But I am unsure how to get this to work using HTML/PHP. At present I only know how to display the studentID and CCode from the courseenrolement table using the following code: <ul> <?php foreach ($courseenrolements as $ce): ?> <li> <form action="" method="post"> <div> <?php htmlout($ce['studentID']); ?> <?php htmlout($ce['CCode']); ?> <input type="hidden" name="courseenrolementid" value="<?php echo $ce['courseenrolementid']; ?>"> <input type="submit" name="action" value="Edit"> <input type="submit" name="action" value="Delete"> </div> </form> </li> <?php endforeach; ?> </ul> which displays this: But I would like the names and course title. I managed to get it to show the names etc in the dropdown on the 'Add new' form, so I would assume it will be similar, but just unsure on how exactly. Thanks in advance

• Prevent box shadow from showing on a specific side

  Is there any way to create a css box-shadow in which regardless of the blur value, the shadow only appears on the desired sides? For example if I want to create a div with shadows on left and right sides and no shadow on the top or bottom. The div is not absolutely positioned and its height is determined by the content. -- Edit -- @ricebowl: I appreciate your answer. Maybe you can help with creating a complete solution to fix the problems stated in my reply to your solution...

• Python C API from C++ app - know when to lock

  - by Alex

  Hi Everyone, I am trying to write a C++ class that calls Python methods of a class that does some I/O operations (file, stdout) at once. The problem I have ran into is that my class is called from different threads: sometimes main thread, sometimes different others. Obviously I tried to apply the approach for Python calls in multi-threaded native applications. Basically everything starts from PyEval_AcquireLock and PyEval_ReleaseLock or just global locks. According to the documentation here when a thread is already locked a deadlock ensues. When my class is called from the main thread or other one that blocks Python execution I have a deadlock. Python Cfunc1() - C++ func that creates threads internally which lead to calls in "my class", It stuck on PyEval_AcquireLock, obviously the Python is already locked, i.e. waiting for C++ Cfunc1 call to complete... It completes fine if I omit those locks. Also it completes fine when Python interpreter is ready for the next user command, i.e. when thread is calling funcs in the background - not inside of a native call I am looking for a workaround. I need to distinguish whether or not the global lock is allowed, i.e. Python is not locked and ready to receive the next command... I tried PyGIL_Ensure, unfortunately I see hang. Any known API or solution for this ? (Python 2.4)

• Data Annotations on ViewModels or Domain Objects

  - by Ahmad

  Where would data annotations be more suitable: ViewModels or Domain Objects or Both I am struggling to decide where these will be more suited. I have not as yet fully utilized them but this question came to mind. From most of the examples I have seen, they are generally placed on Models and simply use the required attributes for validation using ModelState.IsValid. I have also seen another question on SO where the use of data annotations alone is not sufficient and advocate. Option 1 - I will still need to validate again in my service layer. ( I think that my service layer should be complete and this include validation, since its planned to be used elsewhere) Option 2 - How will I then get the benefits of the built in validation both client and server side. Option 3 - there will be a repetition of validation logic, however I was wondering if one could use a MetaData class approach that can be used for both ViewModels and Domain Objects. ( This is completely of the top of my head, so it may be nonsensical) I wonder if this question even makes sense. If not, can someone please help in understanding this better. Have I completely misunderstood the use of data annotations?

• DotNetOpenAuth / WebSecurity Basic Info Exchange

  - by Jammer

  I've gotten a good number of OAuth logins working on my site now. My implementation is based on the WebSecurity classes with amends to the code to suit my needs (I pulled the WebSecurity source into mine). However I'm now facing a new set of problems. In my application I have opted to make the user email address the login identifier of choice. It's naturally unique and suits this use case. However, the OAuth "standards" strikes again. Some providers will return your email address as "username" (Google) some will return the display name (Facebook). As it stands I see to options given my particular scenario: Option 1 Pull even more framework source code into my solution until I can chase down where the OpenIdRelyingParty class is actually interacted with (via the DotNetOpenAuth.AspNet facade) and make addition information requests from the OpenID Providers. Option 2 When a user first logs in using an OpenID provider I can display a kind of "complete registration" form that requests missing info based on the provider selected.* Option 2 is the most immediate and probably the quickest to implement but also includes some code smells through having to do something different based on the provider selected. Option 1 will take longer but will ultimately make things more future proof. I will need to perform richer interactions down the line so this also has an edge in that regard. The more I get into the code it does seem that the WebSecurity class itself is actually very limiting as it hides lots of useful DotNetOpenAuth functionality in the name of making integration easier. Andrew (the author of DNOA) has said that the Attribute Exchange stuff happens in the OpenIdRelyingParty class but I cannot see from the DotNetOpenAuth.AspNet source code where this class is used so I'm unsure of what source would need to be pulled into my code in order to enable the functionality I need. Has anyone completely something similar?

• Accessing memory buffer after fread()

  - by xiongtx

  I'm confused as to how fread() is used. Below is an example from cplusplus.com /* fread example: read a complete file */ #include <stdio.h> #include <stdlib.h> int main () { FILE * pFile; long lSize; char * buffer; size_t result; pFile = fopen ( "myfile.bin" , "rb" ); if (pFile==NULL) {fputs ("File error",stderr); exit (1);} // obtain file size: fseek (pFile , 0 , SEEK_END); lSize = ftell (pFile); rewind (pFile); // allocate memory to contain the whole file: buffer = (char*) malloc (sizeof(char)*lSize); if (buffer == NULL) {fputs ("Memory error",stderr); exit (2);} // copy the file into the buffer: result = fread (buffer,1,lSize,pFile); if (result != lSize) {fputs ("Reading error",stderr); exit (3);} /* the whole file is now loaded in the memory buffer. */ // terminate fclose (pFile); free (buffer); return 0; } Let's say that I don't use fclose() just yet. Can I now just treat buffer as an array and access elements like buffer[i]? Or do I have to do something else?

• google chrome extension update text after response callback

  - by Jerome

  I am writing a Google Chrome extension. I have reached the stage where I can pass messages back and forth readily but I am running into trouble with using the response callback. My background page opens a message page and then the message page requests more information from background. When the message page receives the response I want to replace some of the standard text on the message page with custom text based on the response. Here is the code: chrome.extension.sendRequest({cmd: "sendKeyWords"}, function(response) { keyWordList=response.keyWordsFound; var keyWords=""; for (var i = 0; i FIRST QUESTION: This all seems to work fine but the text on the page doesn't change. I am almost certainly because the callback completes after the page is finished loading and the rest of the code finishes before the callback completes, too. How do I update the page with the new text? Can I listen for the callback to complete or something like that? SECOND QUESTION: The procedure I am pursuing first opens the message page and then the message page requests the keyword list from background. Since I always want the keyword list, it makes more sense to just send it when I create the tab. Can I do that? Here is the code from background that opens the message page: //when request from detail page to open message page chrome.extension.onRequest.addListener(function(request, sender, sendResponse) { if(request.cmd == "openMessage") { console.log("Received Request to Open Message, Profile Score: "+request.keyWordsFound.length); keyWordList=request.keyWordsFound; chrome.tabs.create({url: request.url}, function(tab){ msgTabId=tab.id; //needed to determine if message tab has later been closed chrome.tabs.executeScript(tab.id, {file: "message.js"}); }); console.log("Opening Message"); } });

• Timer Service in ejb 3.1 - schedule calling timeout problem

  - by Greg

  Hi Guys, I have created simple example with @Singleton, @Schedule and @Timeout annotations to try if they would solve my problem. The scenario is this: EJB calls 'check' function every 5 secconds, and if certain conditions are met it will create single action timer that would invoke some long running process in asynchronous fashion. (it's sort of queue implementation type of thing). It then continues to check, but as long as long running process is there it won't start another one. Below is the code I came up with, but this solution does not work, because it looks like asynchronous call I'm making is in fact blocking my @Schedule method. @Singleton @Startup public class GenerationQueue { private Logger logger = Logger.getLogger(GenerationQueue.class.getName()); private List<String> queue = new ArrayList<String>(); private boolean available = true; @Resource TimerService timerService; @Schedule(persistent=true, minute="*", second="*/5", hour="*") public void checkQueueState() { logger.log(Level.INFO,"Queue state check: "+available+" size: "+queue.size()+", "+new Date()); if (available) { timerService.createSingleActionTimer(new Date(), new TimerConfig(null, false)); } } @Timeout private void generateReport(Timer timer) { logger.info("!!--timeout invoked here "+new Date()); available = false; try { Thread.sleep(1000*60*2); // something that lasts for a bit } catch (Exception e) {} available = true; logger.info("New report generation complete"); } What am I missing here or should I try different aproach? Any ideas most welcome :) Testing with Glassfish 3.0.1 latest build - forgot to mention

  - by Kent Boogaart

  I have a web tier that forwards calls onto an application tier. The web tier uses a shared, cached channel to do so. The application tier services in question are stateless and have concurrency enabled. But they are not being called concurrently. If I alter the web tier to create a new channel on every call, then I do get concurrent calls onto the application tier. But I wanted to avoid that cost since it is functionally unnecessary for my scenario. I have no session state, and nor do I need to re-authenticate the caller each time. I understand that the creation of the channel factory is far more expensive than than the creation of the channels, but it is still a cost I'd like to avoid if possible. I found this article on MSDN that states: While channels and clients created by the channels are thread-safe, they might not support writing more than one message to the wire concurrently. If you are sending large messages, particularly if streaming, the send operation might block waiting for another send to complete. Firstly, I'm not sending large messages (just a lot of small ones since I'm doing load testing) but am still seeing the blocking behavior. Secondly, this is rather open-ended and unhelpful documentation. It says they "might not" support writing more than one message but doesn't explain the scenarios under which they would support concurrent messages. Can anyone shed some light on this?

• Loading velocity template inside a jar file

  - by Rafael

  I have a project where I want to load a velocity template to complete it with parameters. The whole application is packaged as a jar file. What I initially thought of doing was this: VelocityEngine ve = new VelocityEngine(); URL url = this.getClass().getResource("/templates/"); File file = new File(url.getFile()); ve = new VelocityEngine(); ve.setProperty(RuntimeConstants.RESOURCE_LOADER, "file"); ve.setProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, file.getAbsolutePath()); ve.setProperty(RuntimeConstants.FILE_RESOURCE_LOADER_CACHE, "true"); ve.init(); VelocityContext context = new VelocityContext(); if (properties != null) { stringfyNulls(properties); for (Map.Entry<String, Object> property : properties.entrySet()) { context.put(property.getKey(), property.getValue()); } } final String templatePath = templateName + ".vm"; Template template = ve.getTemplate(templatePath, "UTF-8"); String outFileName = File.createTempFile("p2d_report", ".html").getAbsolutePath(); BufferedWriter writer = new BufferedWriter(new FileWriter(new File(outFileName))); template.merge(context, writer); writer.flush(); writer.close(); And this works fine when I run it in eclipse. However, once I package the program and try to run it using the command line I get an error because the file could not be found. I imagine the problem is in this line: ve.setProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, file.getAbsolutePath()); Because in a jar the absolute file does not exist, since it's inside a zip, but I couldn't yet find a better way to do it. Anyone has any ideas?
