With DWR, I expected something similar to be required. However, we ended up hacking engine.js like this: if (DWREngine.USER_NAME != undefined) { batch.req.open(batch.httpMethod, request.url, batch.async, DWREngine.USER_NAME, DWREngine.USER_PASSWORD); } else batch.req.open(batch.httpMethod, request.url, batch.async); We would set DWREngine.USER_NAME and DWREngine.USER_PASSWORD after logging in successfully. This works, but I’ve never felt comfortable with it. It’s messy etc. etc. etc. What is the recommended way for doing this? Something like options to be set for the engine?

I was just doing some work on the dwr data store when I found myself needing something like this, and it seems like it could be generally useful. Thoughts? Joe.

On the client side, using javascript, I always get an error when trying to get the innermost List. That is, I can retrieve the outermost List easily, but when I go deeper and get the innermost List, I get an "ERROR" on the DWR test page. Can someone give me an example on how to use nested LIST? Tim Nguyen, Thien 1 (N-Albin Engineering 2008-05-13T00:00:09 http://comments.gmane.org/gmane.comp.java.dwr.user/11138 Greetings I am using DWR with Simple framework (http://www.simpleframework.org/). It has own Simple API which is different from servlet-api. But I use Adaptor pattern to convert simple.Request to HttpServletRequest and HttpServletResponse to simple.Response. Also I am using Reverse Ajax in my web application. Simple request handler receives request and forwards it to the DWR Servlet using DwrServlet.service(request, response) method. DWR Servlet configured properly and it works. Sometimes I have strange behavior: request is being processed 1 minute but method on the class mapped to javascript works only 10 msec. I received this statistic wrapping DwrServlet.service with timer1 and adding timer2 to the my Java class. timer1.maximum value = 1 minute (The maximum time is the same as maximum time for Reverse Ajax request) timer2.maximum value = 10 msec. This situation is hard to reproduce in my local version of the application. But I have this statistic often in the live system. So it is hard to debug it. It seems the number of these errors depends on browser (can't reproduce it with FireFox) and connection quality. (Not sure). Have you idea where the request can be 60 sec in the DwrServlet.service? Thanks in advance.

I'm creating a checkbox for each, naming the checkbox id+"cb" as I iterator through the list. I am disabling the checkboxes to begin with. At a certain point in time, I want to enable the checkboxes one at a time. Is that possible with DWR? This is what I have now and it is not working. Anybody know how I could do this in DWR or how I could tweak this code to work? Thank you... function enableCheckbox(){ var id = dwr.util.getValue("selectOutbuilding"); var name = id+'cb'; document.choiceForm.+ name + .disabled = false; } <c:forEach items="${outbuildings}" var="building"> <input type="checkbox" name="${building.id}cb" disabled="true"> ${building.description}</><BR> </c:forEach> __________________________________________ The information contained in this message may be privileged and confidential and protected from disclosure.

Lauren Riley 2008-05-08T19:34:10 http://comments.gmane.org/gmane.comp.java.dwr.user/11128 Seems like i'm messing too much with connection limit problem. But, here goes my query. In my application, i do "dwr.engine.setActiveReverseAjax(true)" and "dwr.engine.setActiveReverseAjax(false)" time-to-time to reduce the burden of keeping one permanent connection for reverse ajax even if the client does not need it. I want my server also to be aware of this thing i.e, whether there is a reverse ajax connection with a client or not. Explicitly Calling the server is not a reliable approach. I want some sort of listener at the server end which keeps track of when ActiveReverseAjax has been set true/false. Otherwise, can somebody suggest my some way to set ActiveReverseAjax true or false from server side only. Plz somebody help me out.. Hey Joe, are you listening? Nitin Thakur 2008-05-08T09:34:51 http://comments.gmane.org/gmane.comp.java.dwr.user/11123 Is there a way to send back information to only one browser even though multiple browsers are on the given page? My problem is that I have multiple users logged in accessing their data. If there is an update for any given user, I don't want it to be sent to all users currently logged in. I saw a post on how to deal with this if the thread is started by DWR, but in my case it isn't. Also, in the javadoc there is mention of getScriptSession(String id) but I can't find the method anywhere. Maybe I could use this to determine which ScriptSession I need to send updates to. Thanks, Erlend Erlend Sobec 2008-05-07T20:39:22 http://comments.gmane.org/gmane.comp.java.dwr.user/11120 Hi, all, I can successfully display the images returned from dwr call as bufferedImage which is retrieved from database, my problem is that the image is too big to fit my javascript window, I want the image exactly to fit the window, and resize with the window on the browser without going back to call dwr java function again to recalculate, so I mean my javascript program can recalculate the size of the image, with setup like this: day1.jpg I can do that with javascript, but with the dwr retrieved image like this: /webapp/dwr/download/10ED6EDB38A3C797840F9AB2E2764FD2 I can not set style with the size, if I do, it will not display anymore. Any suggestions for me in terms of what to do to resize it with javascript? Thanks in advance. Dave ddduuu 2008-05-07T15:31:49 http://comments.gmane.org/gmane.comp.java.dwr.user/11117 Is there any way to synchronize java-function-calls from javascript without server explicitly sending acknowledgment through reverse Ajax. Say, i want to make a call to method2 (JavaClass.method2) only after my previous call has been completed (JavaClass.method1). is there any way to assure this. Nitin Thakur 2008-05-07T13:58:48 http://comments.gmane.org/gmane.comp.java.dwr.user/11115 Hi, I'm trying to use reverse ajax to publish online events to a web browser. Everything works fine with firefox. In ie6, I get a low update rate. The update period is equal to the parameter I set in "maxWaitAfterWrite" (if I set 5000, the values are updated once every 5 seconds). Setting a lower value increase the update rate but then I get a "memory hog", memory consumption of ie grows very fast until I minimize the window (very strange behaviour). The memory problem seems to be triggered by javascript method call on the java side. I tried to disable all my application logic, but the problem persists. I tried severeral version of DWR (from 2.0.1 to 2.0.4rc1) with no luck. My web application is based on Spring and is deployed on a Jetty6 web server. Any ideas ? Maybe I am doing something wrong ? Damien Damien 2008-05-07T13:11:41 http://comments.gmane.org/gmane.comp.java.dwr.user/11114 If you're at JavaOne, and fancy a meal, or just a few beers, we could all hook up after the comet talk this evening. The talk is in 307-310 and from 6:30 to 7:20. It would be good to meet up, and I'll buy at least the first round. Joe. Joe Walker 2008-05-07T12:24:51 http://comments.gmane.org/gmane.comp.java.dwr.user/11112 Hi everybody, I'm getting a little headache at the moment because of my little test project. I'm writing a small test application using Hibernate and since yesterday also DWR. I already managed to request Collections from Hibernate and display them on the client with this lines: <convert converter="hibernate3" The problem now is that i have in some POJOS collections of other POJOS. example: 1 folder has zero or more sheets 1 sheet has zero or more tags (which are stored in a collection) When i request all sheets from the server i return a collection of sheets. That works perfectly. I want to display all sheets in a simple HTML table. Per sheet i also want to list all tags that belong to that sheet. The problem now is that the collection that holds all the tags per sheet is null. Is there another way (another option) that i missed to let DWR also return the collections that belong to one object? Thanks a lot already for DWR. It's a really nice tool. martin krüger 2008-05-07T08:13:40 http://comments.gmane.org/gmane.comp.java.dwr.user/11106 var answer=false; function callDWR(){ MyClass.doSomething(returnFunction); } function returnFunction(result){ answer =result; } //my javascript to call the above functions... callDWR(); if(answer){ //do something else } is it possible to wait for dwr to return result before executing the subsequent code? in other words, wait for dwr to return result before calling if(answer)... --------------------------------- Be a better friend, newshound, and know-it-all with Yahoo!

I find the "include" and "exclude" parameters of the BeanConverter very useful. Is it possible to use wildcards in include/exclude definitions? I would like to do something like: <convert converter="bean" match="MyClass"> <param name="exclude" value="str*"/> </convert> and expect DWR to exclude all member variables of MyClass that start with "str". Thanks, Gabor se 2008-05-05T12:41:46 http://comments.gmane.org/gmane.comp.java.dwr.user/11101 Hi all... I'm looking for a way I can gain access from my own code to the DWR configuration information... I'm working on an extension to DWR and I need to be able to read the dwr.xml file (or configurations resulting from annotations). I assume they're floating around somewhere, I shouldn't have to parse the file myself or something like that, but I've been pouring over the javadoc for the last 20 minutes and haven't found what I'm looking for... the next step is to tear into the code and figure it out, but I'm hoping someone can point me in the right direction quickly.
