The basic loading is in scrambled and all the pages are in total CSS mess which we need to clean up unfortunately.For this I require a tool which works similar to firebug for Mozilla.Also to check headers, cookies, caching and POST data ,compression, redirection & chunked encoding a similar tool to HTTP watch is also desired. Any suggestions.Thanks

• HTML muliple select should look like HTML select

  - by GustlyWind

  Hi I am trying to use a HTML select box with 'multiple' select options and size to 1 as below ` <SELECT NAME="toppings" MULTIPLE SIZE=5> <OPTION VALUE="mushrooms">mushrooms <OPTION VALUE="greenpeppers">green peppers </SELECT> When the size is set to 1 small scrollbar appears which makes the page clumsy.If I increase the size its eating up my page since there are around 20 such multiple boxes in and around the page. I am looking for a solution which looks like <SELECT> but should function as multiple Is this possible. I remember seen something similar but don't remember exactly. Any ideas

• Quartz job fires multiple times

  - by GustlyWind

  Hi, I have a building block which sets up a Quartz job to send out emails every morning. The job is fired three times every morning instead of once. We have a hosted instance of Blackboard, which I am told runs on three virtual servers. I am guessing this is what is causing the problem, as the building block was previously working fine on a single server installation. Does anyone have Quartz experience, or could suggest how one might prevent the job from firing multiple times? Thanks,

• Velocity framework servlet

  - by GustlyWind

  I have a module written in servlets and needs to be recently moved to velocity framework So in the process I am rewriting the web.xml to create velocity servlet object whcih calls our original servlet . Now if this has to be moved to <servlet> <servlet-name>VeloServlet</servlet-name> <servlet-class>org.apache.velocity.tools.view.servlet.VelocityViewServlet</servlet-class> </servlet> How can we acheive this and what are all changes need to use the existing servlet as it is. My Existing servlet looks like <servlet-name>DataBridgeServlet</servlet-name> <servlet-class>com.jda.pwm.databridge.framework.common.DataBridgeServlet</servlet-class> <init-param> <param-name>jda.databridge.config.path</param-name> <param-value>d:/usr/databridge/conf</param-value> </init-param> This is loaded using the url http://localhost:8080/databridge/databridgeservlet So in the newer case how velocity servlet calls this servlet

• Curious to Know what Eclipse 'Show Heap Status' does

  - by GustlyWind

  Hi All In Eclipse (I am using 3.4 Ganymede) there is an option under Preferences>General>Show Heap Status which when checked shows near bottom of IDE like 46M of 98M and if we move the mouse over 'Recycle Bin' it says 'Run Garbage Collector'. I am curoius to know how this works.What will happen when 'Run Garbage Collector' is clicked. My enivroment set up is something like jdk6 is insatlled and IDE used for development and run in Tomcat server. So my understanding is all the objects which are run through Tomcat should be garbage collected. Is this correct. Is there a way to see what objects Eclipse identified as Garbage Cheers

• Blob object not working properly even though the class is seralized

  - by GustlyWind

  I have class which is seralized and does convert a very large amount of data object to blob to save it to database.In the same class there is decode method to convert blob to the actual object.Following is the code for encode and decode of the object. private byte[] encode(ScheduledReport schedSTDReport) { byte[] bytes = null; try { ByteArrayOutputStream bos = new ByteArrayOutputStream(); ObjectOutputStream oos = new ObjectOutputStream(bos); oos.writeObject(schedSTDReport); oos.flush(); oos.close(); bos.close(); //byte [] data = bos.toByteArray(); //ByteArrayOutputStream baos = new ByteArrayOutputStream(); //GZIPOutputStream out = new GZIPOutputStream(baos); //XMLEncoder encoder = new XMLEncoder(out); //encoder.writeObject(schedSTDReport); //encoder.close(); bytes = bos.toByteArray(); //GZIPOutputStream out = new GZIPOutputStream(bos); //out.write(bytes); //bytes = bos.toByteArray(); } catch (Exception e) { _log.error("Exception caught while encoding/zipping Scheduled STDReport", e); } decode(bytes); return bytes; } /* * Decode the report definition blob back to the * ScheduledReport object. */ private ScheduledReport decode(byte[] bytes) { ByteArrayInputStream bais = new ByteArrayInputStream(bytes); ScheduledReport sSTDR = null; try { ObjectInputStream ois = new ObjectInputStream(bais); //GZIPInputStream in = new GZIPInputStream(bais); //XMLDecoder decoder = new XMLDecoder(in); sSTDR = (ScheduledReport)ois.readObject();//decoder.readObject(); //decoder.close(); } catch (Exception e) { _log.error("IOException caught while decoding/unzipping Scheduled STDReport", e); } return sSTDR; } The problem here is whenver I change something else in this class means any other method,a new class version is created and so the new version the class is unable to decode the originally encoded blob object. The object which I am passing for encode is also seralized object but this problem exists. Any ideas thanks

• How to MakeTable ReadOnly including contents like images

  - by GustlyWind

  I have a table which has two text boxes and a image beside it to click and open a popup. In read-only mode based on condition I am able to make text boxes read-only but images are not becoming read-only.One solution I had is the anchor tag associated with image calls for JavaScript where I can check for a dummy click when it is in read-only mode. The problem here is the function is common and effects everywhere. So is there a way to make the entire table read-only so that no extra workaround needs to done. Edited for code <table> <tr> <td class="lightbg" colspan='4'>&nbsp; Expires:<input type="TEXT" value="" id="element1" name="expireDate" size="10" maxlength="20" class="" onChange="javascript:validateDateEntry('element1',true);;"> Period:<input type="TEXT" value="" id="element2" name="refershDate" size="10" maxlength="20" class="" onChange="javascript:validateDateEntry('element2',true);;"> &nbsp; <a href="javascript:doCalendar('element1');"> <img src="/PWM/images/images_2006/calendarbtn.gif" border="0" alt="Click to select date from calendar" align="absmiddle"> </a> </td> </tr> <tr> <td colspan='4'><b>*</b>Times are in the WFM Server's Time Zone.</td></tr> </table> Thanks

• How to increase the performance of a loop which runs for every 'n' minutes.

  - by GustlyWind

  Hi Giving small background to my requirement and what i had accomplished so far: There are 18 Scheduler tasks run at regular intervals (least being 30 mins) takes input of nearly 5000 eligible employees run into a static method for iteration and generates a mail content for that employee and mails. An average task takes about 9 min multiplied by 18 will be roughly 162 mins meanwhile there would be next tasks which will be in queue (I assume). So my plan is something like the below loop try { // Handle Arraylist of alerts eligible employees Iterator employee = empIDs.iterator(); while (employee.hasNext()) { ScheduledImplementation.getInstance().sendAlertInfoToEmpForGivenAlertType((Long)employee.next(), configType,schedType); } } catch (Exception vEx) { _log.error("Exception Caught During sending " + configType + " messages:" + configType, vEx); } Since I know how many employees would come to my method I will divide the while loop into two and perform simultaneous operations on two or three employees at a time. Is this possible. Or is there any other ways I can improve the performance. Some of the things I had implemented so far 1.Wherever possible made methods static and variables too Didn't bother to catch exceptions and send back because these are background tasks. (And I assume this improves performance) Get the DB values in one query instead of multiple hits. If am successful in optimizing the while loop I think i can save couple of mins. Thanks

• slowness in IE 8 IE9 while drawing tables in a html page

  - by GustlyWind

  My HTML page contains many tables,with numerous tr and td. While rendering in IE8/IE9 the its very slow but in Firefox its fast. I had read somewhere while drawing tables if the tables are not of fixed width, IE calculates the width every time and renders so usually slow. Right now i am adding Table style="table-layout:fixed" which made me feel its faster. Are there any similar styles that can be added to tr and td as well.Also suggest if there any other attribtes that can be added to a table
