How to specify a JRE range in jnlp file?

We have a java app which uses Java Web Start. The jnlp file is configured with [j2se version="1.5+"]. So if JRE 1.5 and 1.6 are installed, the app is run on 1.6.
Now, we have requirement where the app should be restricted to run only within the range - JRE 1.5.0_07 through JRE 1.5.0_17
[j2se version="1.5*"] will not work - it will always launch the app with the latest jre from 1.5 family.
I can request an exact product version by including the href attribute. [j2se version="1.5.0_14" href="http://java.sun.com/products/autodl/j2se"/]
But how do I specify a specific range of JREs in the jnlp file so that JWS picks up a JRE from that range only? So if 1.5.0_07, 1.5.0_17 and JRE 6 are installed, it should run the app on 1.5.0_17.
Can JNLP really allow you to select specific range of JREs? Is there a good way to accomplish this? Please help.

Several JREs can be specified, which indicates a prioritized list of the supported JREs, with the most preferred version first. For example,
    <java version="1.3" initial-heap-size="64m"/>
    <java version="1.2">
      <resources> ... </resources>
    </java>So your app. would need more along the lines of..
    <java version="1.5.0_07 1.5.0_08 1.5.0_09 1.5.0_10 1.5.0_11 1.5.0_12 1.5.0_07 1.5.0_13 1.5.0_14 1.5.0_15 1.5.0_16 1.5.0_17 " />
    <java version="1.6+" />Actually you'd need the list of 1.5 versions reversed. Well, you get the idea hopefully. For more on versioning, see my [JWS versioning page|http://pscode.org/jws/version.html].

  • t:inputCalendar How To Specify a Date Range?

    <-- Sorry for my english. -->
    Can anybody help me?
    I want to know how to specify a date range in the <t:inputCalendar/> component. I'm using Tomahawk/Apche implementation. So that the user cannot specify a date outside that range.
    Thanks.

    I don't think that the inputCalendar tag supports that directly. However, you could add a validator to the component.

  • Using DRS to specify Java version when executing JNLP file.

    We have an application that executes from a JNLP file that we are told is version sensitive.  We have a rule set created for a number of apps that work just fine to meet this goal.  However, when creating a rule to execute this JNLP application we are having issues getting it to work.  To simplify the process we created a certificate hash rule for this application and when reviewing console\trace we can see it correctly identifying and executing under the Java 6U29 environment.  The issue is that even though 6u29 is being invoked it does not work (merely displays a "application error" message).  However, if I instead launch the JNLP file using the Javaws.exe in the 1.6.0_29 folder the app loads fine.  When comparing behavior with the rule set environment and a 6u29 only environment I saw some peculiar entries.

    So it appears that the 6u29 version of Javaws.exe is getting called however some of the configured paths are being set to the 8u25 path.  Not sure if its a cause but does seem to be relevant since on the exact same system if I run the JNLP specifically with the 6u29 exe it works as expected.  Any assistance would be appreciated.

  • How to specify minimum JRE but never download if not there

    Our clients want to control what version of the JRE is installed. We want the JNLP to specify a minimum JRE version. We never want to download and install the JRE via our app -- instead, our clients are supposed to have some minimum version installed as a prerequisite.
    Is there a way to specify this in the JNLP with the <j2se> tag? I can't seem to find a way to bypass the Web Start behavior where it wants to download the JRE if it can't find it.
    If the minimum JRE does not exist, the clients would like to see a message (probably a web page) indicating this, with further instructions.
    Is this possible (or does it even make sense) with Web Start? Or should we be looking elsewhere? (Our other option is to create our own installer -- the app runs on Windows).

    >
    In all our testing, our experience is that the JRE is downloaded whether or not an href is specified. It'll just go to the default Sun location if it's not specified. >Test this.
    It requests version 1.9.0_02, and from here, reports,
    Unable to launch the application.If I click the details button of that error dialog, hidden at the bottom of the Console tab is the message ..
    #### Java Web Start Error:
    #### The application has requested a version of the JRE (version 1.9.0_02) that
      currently is not locally installed. Java Web Start is unable to automatically
      download and install the requested version. This JRE must be installed manually.Edit 1:
    As an aside, if you really want to resolve this, I recommend ..
    - Validate your JNLP files against the DTD or XSD.
    - If it still does not work as you expect, post the JNLP content to the forum.
    - Add 10 Duke stars, to indicate you are very interested in a solution.

    And note that Luca-Sanna was referring (I expect) to the href attribute of the J2SE element, as opposed to any other href, such as the one in the JNLP element. The JNLP I linked to has two href attributes, neither of which are associated with the J2SE element in the resources section.

  • How to specify fonts in text in SVG file?

    I've got an Edge Animate composition that includes a bunch of SVG files which specify (inside the svg files themselves) that a particular font should be used. So for instance, there's text in the SVG that's set to render in Arial. If I view that SVG by itself in the browser, the text is rendered in Arial. But when that SVG is part of an Edge composition, the text in that SVG reverts to some other default font.
    The same problem happens when I try to specify a custom web font inside the SVG. The web font shows up fine when viewing the SVG independently, but when it's part of an Edge composition, it reverts to a default (Some serif font: Times, I think.)
    Let me stress this is NOT about specifying the fonts in Edge itself (by adding the web font to the edge composition, and then styling text from within the Edge Animate interface): this is about text that has been specified in the SVG file in Illustrator. That font specification is ignored when the SVG is brought into Edge.
    This text in the SVG shows as Arial when I'm in the Edge Animate interface, but when I view the whole composition in the browser, that's when it reverts to a different font.
    Any ideas what's going on here?

    Thanks for the reply. Yes, I've given up on fonts embedded in SVGs for now. I tried using SVGs with all text converted to outlines. That solved the type problem. But it of course made all the SVGs very large. I'm now having a problem with the Edge composition not fully loading.
    It throws some javascript errors that indicate that al the libraries haven't loaded. Or, sometimes it just pulls up a blank page and nothing ever shows up, even when there are no javascript errors. The errors are mostly this:
    Uncaught ReferenceError: jQuery is not defined byod_edgeActions.js:191(anonymous function)byod_edgeActions.js:191
    Uncaught TypeError: Object #<Object> has no method 'okToLaunchComposition' byod_edgePreload.js:27
    edgeCallbackbyod_edgePreload.js:27
    (anonymous function)byod_edgePreload.js:15
    tbyod_edgePreload.js:11
    dbyod_edgePreload.js:10
    I.b.onreadystatechange.b.onloadbyod_edgePreload.js:10
    So I'm thinking the loader is trying to move on to execute code when it hasn't loaded what it needs. This was happening on Firefox and Chrome. So now I've converted some of the larger SVGs to PNGs, which brought their file size down considerably. This eliminated the error on Firefox, but I'm still getting it in Chrome. I think it's just taking too long to load all my animations. It's a pretty big composition: an infographic that's 548 px wide by 3100 px tall. It has 8 animations in it, each as a symbol. There are perhaps 80 individual graphic elements in total that are involved in the animations.
    Even when those graphic files are as small as I can make them, Chrome still errors out before displaying anything.
    If it just turns out that this is too big a composition to be done in Edge Animate, I'm in big trouble, as a client has already paid for this.
    I'm hoping I can find a way to slow down the loader and make it wait until everything is loaded before moving on. But it's tough, as the edgePreload.js file wasn't meant to be tampered with, and is minified. I don't mind having a preload image appear for a while with a "loading..." message. But if it never loads...
    Not sure how to proceed, really.

  • How to read a certain range from binary file

    Dear all LabView experts!
    I've attempted to acquire data as fast as I can from TDS 2024 via GPIB interface. The data will be saved into one binary file and be used for later analysis.
    The program that is included here will perform continuous acquiring and save all the points into 1 file.
    I used WHILE loop to do this job and each loop will take 2500 points from the scope.
    After that, I would like to read the file such that every 2500 points will be read out and analyzed.
    can you please show me how to do this?
    I've acknowleged that 2 inputs: pos. mod and pos.offset should be able to provide random access to the binary at any point. However, I cannot have this done
    THank you very much

  • How to specify  inclusion and exclusion rules for File data sources

    This is the seed URL for a file data source: file://localhost/c:/myDir/
    I want to exclude indexing and searching of files under: file://localhost/c:/myDir/obsolete/
    What is the exact format for the exclusion URL?
    I have tried both file://localhost/c:/myDir/obsolete/ and /myDir/obsolete/
    but neither of it seems to work; it still indexes everything under /myDir/
    Should I just put: /obsolete/ as the exclusion URL?
    Also after initial crawling, if I change the inclusion and or exclusion rules and then run the crawler again, it should update the indexes accordingly. Is that right?
    The version of UltraSearch I am using is 1.0.3.
    Thanks for any help on this.

    Try "/c:/myDir/obsolete/"
    Changing inclusion/exclusion rule does not affect files already crawled. It onyl
    affects next crawling behavior.
    To do any DML to existing data set, use SQL directly on wk$url table under the instance owner.

  • Specific version of jre in .jnlp file and downloading from local server

    Hi,
    I have couple of questions regarding the specific version of jre in Java WebStart.
    1) I have specified the jre version in .jnlp file as below.
    <resources>
    <j2se version="1.3.1_02"/>
    </resources>
    When I saw the File/Preferences/Java of Java WebStart installation, there is an entry with the "Product Version" value as 1.3.1_02 as I installed jre also before launching my application. Still it complains as,
    The application has requested a version of the Java 2 platform (JRE) that is currently not locally installed. Java Web Start was unable to automatically download and install the requested version. The JRE version must be installed manually.
    Error Code 11 (11 Could not locate requested version) returned from server when accessing resource: (http://java.sun.com/products/autodl/j2se, 1.3.1_02)
    When it is there already, why it is trying to get from the Sun's site.
    2) I want Java WebStart to download the specified version of jre from my local server, I specified this in the following way,
    <resources os="Windows">
    <j2se version="1.3.1_02" href="http://host:9095/j2re-1_3_1_02-win.exe"/>
    </resource>
    I got the error saying,
    Bad MIME type returned from server when accessing resource: (http://host/j2re-1_3_1_02-win.exe, 1.3.1_02) - application/octet-stream. where host is my server name. What I need to do here.
    Can I have multiple resource tags one for each os.
    Help is highly appreciated.
    Thanks,
    Sreedhar.

    Hi Sreedhar,
    There are some other useful threads in this forum on this topic:
    the "Automatically Installing the IBM JRE 1.2.2" thread has tips from somebody who's put together auto-download of JREs from his own web site:
    http://forum.java.sun.com/thread.jsp?forum=38&thread=71061
    Also, the behavior of the j2se tag is discussed a little in the "Using a specific JRE" thread: http://forum.java.sun.com/thread.jsp?forum=38&thread=158075
    The first step is to add an href attribute to your j2se tag. I was just experimenting with this this afternoon,
    and it appears that unless that href is specified (even if it's the java.sun.com default autodl URL!) JWS will not properly check locally-installed 1.3.1 JREs. Once you include Sun's autodl URL as an href, JWS will at least properly enforce the product version among locally-installed JREs. Of course, Sun doesn't actually include 1.3.1 in its autodl section, so it won't download it for you, but it will enable checking of the JREs already installed.
    The second step is downloading JREs from your own web site, which is more complicated and explained better by other messages in the forum. But basically, JWS is not simply looking for a .exe installer for a particular JRE. It hits the webserver with a query and expects the webserver to give it back an installer's JNLP file. Look at the referenced threads for more details.

  • Problem changing JNLP file association

    I installed SUN JRE 1.5 Update 7 in a fresh Windows XP machine and found the registry recongizes the JNLP file extension is associatied with it. Then I installed an application that downloads IBM WebSphere Application Client 6 which actually uses IBM JRE 1.4.2 . After this installation IBM JRE changes the .jnlp file association from Sun JRE 1.5.0_07 to its own 1.4.2 version.
    Now I needed to change the JNLP file association back to previous one. I used Windows Explorer->Tool->Folder Options->File Types->Advanced->Edit and did that. However, I see my registry didn't change the association from IBM JRE to Sun JRE. But when I look at Java Control Panel, it says its associated with Sun JRE. Here is a windows shell script that I run to see the current JNLP file assocaition - which alwasy tells me its OBM JRE which is associated with the JNLP file extension. I tried restarting the machine, removing the cached copy from Java Control Panel without any difference.
    Can you tell me when this file type association may not work and why? Is there any Windows Security Patch issue here? Also what are the registry keys that I should look for (a few are mentioned in the script below)?
    code:
    // To run it:
    // CScript //Nologo JWS.js
    var fso = new ActiveXObject("Scripting.FileSystemObject")

    var ver = gShell.RegRead(regKey + "\\CurrentVersion")
    var path = gShell.RegRead(regKey + "\\" + ver + "\\Home")
    var javaws = path + "\\javaws.exe"
    print("Sun JWS")
    print("\tversion: " + ver)

  • Passing arguments from jnlp file to application

    Hi,
    I am using a jnlp file to launch an application. This is working perfectly. Now I want my application to get some custom properties for making an rmi connection . The only place where I must specify this is in the jnlp file which is dynamically generated. The dynamically generated JNLP file contains:
    <property name="abc.rmi.adapter.host" value="localhost"/>
    <property name="abc.rmi.adapter.port" value="5050"/>
    <property name="abc.rmi.adapter.servicename" value="abc/RMIClientAdapter/"/>
    This does not work.
    However, according to sun only certain types of properties are supported by jnlp for security reason. Is there any way to get over this and have my custom properties. Any help will be appreciated.
    Thanks,
    dasappan

    If you are trying to use RMI, you probably need all-permissions allready.
    for applications requesting all-permissions, all of the properties set in the jnlp file will be set as system properties before the applications "main" is called.
    If you are not using <security><all-permissions/></security>, then only specific trusted properties, plus any begining with "javaws." or "jnlp." will be allowed.
    For properties you just need to pass to yourself, just append "jnlp." to the front of them.

  • JNLP file caching

    I have a JNLP file that does not include <offline-allowed/>. How long does JWS cache such a JNLP file?
    The reason I ask is that I had a bug (my fault) with which the JNLP file didn't correctly reference itself---it referenced a non-existent JNLP file. JWS gave me an error, but the JNLP file it listed in the error report was a different JNLP file altogether---one that I was working on earlier, and that didn't even exist anymore!
    How can I make sure the JNLP file is never cached? Do I have to send all sorts of headers to turn of the cache, such as Pragma: no-cache and the like?
    Garret

    Ooh, this is really bad.
    JWS apparently caches the JNLP uses it for any remote JNLP accessed at the same remote URL ignoring any URL query parameters!.
    I have a JNLP that is dynamically generated at example.com/jnlp?param=value
    Once I've downloaded the application, JWS tucks it away and uses it forever and ever!
    If later I try to access a different JNLP at example.com/jnlp?param=anothervalue, JWS completely ignores the contents of the actual JNLP it gets from the web and uses its locally cached version, which of course has a different href than the one that was generated from example.com/jnlp?param=anothervalue. JWS then tries to go get the JNLP from the wrong href, either retrieving a different JNLP or giving an error.
    What can I put in my JNLP to tell JWS not to cache it? Why doesn't JWS look at the whole URL, or look at times and dates, or something rather than just blindly caching my JNLP?

  • Jnlp file downloads then opens in TextEdit

    Have multiple Macs running 10.5.7 w/latest software update. Each trying to use the same web application. Web app downloads a .jnlp file. For most Macs, it launches Java and life is good. On a lone Mac (so far), the .jnlp file downloads, but is opened by TextEdit. Check File Info, and it's associated with TextEdit, so there's the culprit. On the working Macs, the file is associated with Java Web Start.app. So, I figured I'd change the association on the Mac that's broken, but I can't find Java Web Start.app. It doesn't show up in Spotlight, so I use the locate command in Terminal and find it listed as being found in /Applications/Java. This folder does not exist on any of the Macs in this scenario. Where is it?! How do I fix the association for .jnlp files to be Java Web Start.app?
    Thanks!

    I have the same problem. After running the latest Java update, Java Web Start is gone. I have Xcode installed on my machine, but still don't have Java Web Start anywhere on my drive.
    I attempted to restore it to /Applications/Utilities/Java using Time Machine, but when I launched it, it merely crashed.
    I understand that part of the Java update was to patch a vulnerability that could be exploited through Java applications launched from the web, but I was under the impression that there was a fix that didn't simply involve disabling Java Web Start. Is there a new version of Java Web Start out there that doesn't crash with the new Java update? Alternately, is there a way to run a jnlp file without a working version of Java Web Start?
    I have a program that I absolutely need to have running in the next 30 minutes -- which doesn't give me enough time to roll back the whole update. Is it too much to expect Apple to fix what they broke with this update?

  • How do I specify the JRE i wish to use to Run an Application.

    Hi Everyone;
    Please bear with me if you read this before.
    I have installed java 1.3.1 and java 1.4.1 in that order.
    The JRE used by default is java 1.4.1
    How do I specify the JRE I wish to use to Run an Application from a command prompt.
    Example:
    Java -something org.jboss.Main
    help ??
    Stephen

    I was a lil embarrassed. I told my supervisor that the installation of java overwrites the JRE and that's that.
    My supervisor took 10 minutes and went through it and found java.exe in the System32 file.
    The java.exe file is found in guess where "C:/WINNT/System32/" folder how nice. C:/WINNT/System32/ is in the path. Not only that it's the first entry in the path. So when I execute java it is not using java.exe any one of the java files that I got from the java website.
    So I don't have any control over the version.
    Oh well;
    That's life. That's 1 for my supervisor.
