Yes, the four characters.

null.

Thanks, I am going over the XPath Expressions.
The expressions were not correct.

Able to retrieve the values from the same.

Thanks, I tried both "\\" and "\". When I print on the console, I get to see only null.
But the iterations exactly match the <jar> under <test> only. But, how do I retrieve the value say 3, 4 or 8, 9.

Thanks,
Ananth

I am newbie to XPath. I have the below file, to parse and retrieve the <jar> under <test> only and ignore <jar> under <subcomponent>. I am using XPath for the same.

<xml> <test name="1"> <jar>3</jar> <jar>4</jar> <subcomponent name="1"> <jar>5</jar> </subcomponent> </test> <test name="2"> <jar>8</jar> <jar>9</jar> <subcomponent name="2"> <jar>11</jar> </subcomponent> </test> </xml>

The code,
DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance(); domFactory.setNamespaceAware(true); DocumentBuilder builder = domFactory.newDocumentBuilder(); Document doc = builder.parse("test.xml"); XPathFactory factory = XPathFactory.newInstance(); XPath xpath = factory.newXPath(); XPathExpression expr = xpath.compile("//test//jar"); Object result = expr.evaluate(doc, XPathConstants.NODESET); NodeList nodes = (NodeList) result; for (int i = 0; i < nodes.getLength(); i++) { System.out.println(nodes.item(i).getNodeValue()); } } catch (Exception e) { e.printStackTrace(); }

When I retrieve, I am not getting the value. Please someone help me.

Thanks, used the console to debug the message, included system property webstart/true. All worked fine.

Thanks, when I relaunch clearing the cache, I am able to access the jars. But when I move the same jar to sub folder, /myapp/jars/apps. Then I get to see the message on the console when I launch JNLP file,

# /myapps/jars/main.jar # /myapps/jars/jcalendar.jar # \myapps\jars\apps\jdi.jar(The system cannot find the path specified) # /myapps/jars/jGo.jar

Any pointers on where to look and possible cause of not recognizing the folder.

Thanks,

Hi,

I have the below JNLP file. I have created the appropriate folders, when the jnlp file downloads, message the system cannot find the specified path is seen at the console.

<?xml version="1.0" encoding="UTF-8"?> <jnlp spec="1.5" codebase="http://localhost:8080/myapp/jars"> <information> <title>MyApp</title> <vendor>MyApp</vendor> </information> <resources> <jar href="main.jar"/> <jar href="jcalendar.jar"/> <jar href="apps/jdi.jar"/> <jar href="JGo.jar"/> </resources> <security> <all-permissions/> </security> <application-desc main-class="com.myapp.jars.Main"> </application-desc> </jnlp> Java Web Start 1.6.0_22 Using JRE version 1.6.0_22-b04 Java HotSpot(TM) Client VM User home directory = C:\Documents and Settings\ <---------------------------------------------------- c: clear console window f: finalize objects on finalization queue g: garbage collect h: display this help message m: print memory usage o: trigger logging p: reload proxy configuration q: hide console r: reload policy configuration s: dump system and deployment properties t: dump thread list v: dump thread stack 0-5: set trace level to /myapps/jars/main.jar /myapps/jars/jcalendar.jar \myapps\jars\apps\jdi.jar(The system cannot find the path specified) /myapps/jars/jGo.jar

I have the jars signed, and placed them under the folder jars/apps/jdo.jar

Could some one help me.

Also, tried launching from the url, it prompts me to open/save the jar file. When I include along with other jars within jars folder, the console throws Unable to load the resource file (jdi.jar)
com.sun.deploy.net.FailedDownloadException: Unable to load resource: http://localhost:8080/myapp/jars/jdi.jar at com.sun.deploy.net.DownloadEngine.actionDownload(Unknown Source) at com.sun.deploy.net.DownloadEngine.getCacheEntry(Unknown Source) at com.sun.deploy.net.DownloadEngine.getCacheEntry(Unknown Source) at com.sun.deploy.net.DownloadEngine.getResourceCacheEntry(Unknown Source) at com.sun.deploy.net.DownloadEngine.getResourceCacheEntry(Unknown Source) at com.sun.deploy.net.DownloadEngine.getResource(Unknown Source) at com.sun.javaws.LaunchDownload$DownloadTask.call(Unknown Source) at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)

I have a fixed table layout with width being 425px. It is a table with 200 rows. When the user un-select the checkbox specifying the column, the column is hidden. When the column is hidden, the table is left with the space on the hidden column and the other column width is resized.
Could some one point me on the fix?

.sortable {width: 425px;border: 2px solid #900;border-collapse:collapse;table-layout: fixed} .sortable th {text-align:left;border: 1px solid #fff} .sortable thead th.sub0 {text-align: center;color:#fff;font-size:115%;background: #88b8db repeat-x 0 -1400px;padding: 2px} .sortable tbody th.sub0 {text-align: center;font-size:90%;color:#000;background: #efefef repeat-x 0 -100px;padding: 5px} .sortable tbody th.sub1 {word-wrap:break-word;text-align: left;font-size: 90%;color: #000;background: #efefef repeat-x 0 -100px;padding: 6px}


<table class="sortable" id="table_id"> <col width="45"> <col width="180"> <col width="200"> <thead> <tr> <th class="sub0" id="tcol1">ID</th> <th class="sub0" id="tcol2">File Name</th> <th class="sub0" id="tcol3">Path</th> </tr> </thead> <tbody></tbody> </table> <br/> <form name="tcol" onsubmit="return false"> Show Columns   <input type=checkbox name="col1" onclick="toggleVis(this.name)" checked> Id  <input type=checkbox name="col2" onclick="toggleVis(this.name)" checked> File Name  <input type=checkbox name="col3" onclick="toggleVis(this.name)" checked> Path  </form>

And the java script,

<script type="text/javascript"> var showMode = 'table-cell'; if (document.all) showMode='block'; function toggleVis(btn) { btn = document.forms['tcol'].elements[btn]; cells = document.getElementsByName('t'+btn.name); mode = btn.checked ? showMode : 'none'; for(j = 0; j < cells.length; j++) cells[j].style.display = mode; } </script>

Hi All,

I need some pointers to start on fixing the box model issue. The layout is nice in FireFox browser and in IE it is ugly. I am using to specify the width, height in px and start to debug in both IE and FF using Development Tools and Firebug for FF.

Typically,
.sortable {border: 2px solid #900;border-collapse:collapse} .sortable th {text-align:left;border: 1px solid #fff} .sortable thead th.col1 {height: 20px;width: 45px;text-align: center;color: #fff;font-size: 115%;background: #88b8db url("images/sprites.gif") repeat-x 0 -1400px} .sortable thead th.col2 {height: 20px;width: 150px;text-align: center;color: #fff;font-size: 115%;background: #88b8db url("images/sprites.gif") repeat-x 0 -1400px}

<html> <table class="sortable"> <thead> <tr> <th class="col1" id="tcol1">ID</th> <th class="col2" id="tcol2">File Name</th> </tr> </thead> </table> </html>


When I debug in IE 8 using development tools, the width is 266 X 24 and I have specified 150px on col2.

Could some one point me on the same.

Thanks,

I will have the properties file copied to the WEB-INF/classes folder using ANT script like other cfg files.

Ananth Ram

I meant the web project.

Root--> test.properties, file included.
Root --> src is the folder where my struts action package and other java code resides.
Root --> web is the folder where the jsp, css/images,etc resides.

I want to place the file under the root folder and read the same. Please let me know if I am not clear.

Thanks,
Ananth Ram

Hi All,

I have created a properties file under the root of my project. I would like to read the file to retrieve some config values. Could some one point out the path to determine the file.

I am able to read the file when I place the file under WEB-INF/classes/test.properties with the below code.

Properties prop = new Properties(); prop.load(this.getClass().getResourceAsStream("/test.properties"));

Thanks in advance for your help. It is a JSP / Struts application.

The "text/plain" works fine.


protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { try { response.setContentType("text/plain"); String file = request.getParameter("file"); String fileName = getServletContext().getRealPath(file); String source = ""; FileInputStream fstream = new FileInputStream(fileName); DataInputStream in = new DataInputStream(fstream); BufferedReader br = new BufferedReader(new InputStreamReader(in)); String sLine; PrintWriter out = response.getWriter(); while ((sLine = br.readLine()) != null) { out.println(sLine); } in.close(); out.close(); } catch (Exception e) { e.printStackTrace(); } }

Thanks for pointers.

Ananth Ram

Also the file does not have an extension like txt/doc. It is plain. I tried setting to "text/plain", did not work.

Thanks,
Ananth Ram

Thanks Bear,

So, do you mean I need to specify just text instead of "text/html", or any other options. Please let me know.

Thanks,

Hi All,

I am trying to open a license file using Servlet in a new browser window. The file opens, but the format is not correct.

Example , input file is as below.

GNU GENERAL PUBLIC LICENSE Version 3, 29 June 2007 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
In the browser, the output is as below.
GNU GENERAL PUBLIC LICENSE Version 3, 29 June 2007 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Typically my code in the servlet is below.

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { try { String file = request.getParameter("file"); String fileName = getServletContext().getRealPath(file); String source = ""; FileReader fr = new FileReader(fileName); for(int c = fr.read(); c != -1; c = fr.read()){ source += (char)c; } response.getWriter().write(source); } catch (Exception e) { e.printStackTrace(); } response.setContentType("text/html;charset=UTF-8"); }

Am I missing something on formatting/contentType. Could someone help me out.

Thanks in advance for your help.
