Java 1.5 required for Web Start?

I just got our application to download and run through JWS, but it appears that WebStart is forcing all my clients to upgrade their JRE to 1.5. My JNLP clearly specifies 1.4.2+ as the required JRE, however. Is there somewhere other than the JNLP that the JRE version might be specified, or is there some kind of 1.5 requirement? Maybe it's just downloading the most recent version by default?
Thanks,
Dave

can u post your JNLP file

How can I enable java applet plug-in and Web Start applications via terminal?

Since the last Java update to Snow Leopard, I have found that the system periodically disables the Java applet plug-in after a period of disuse. I know I can go to /Applications/Utilities/Java Preferences and just click to re-enable Java. But I want to write a script which will do this periodically for a couple hundred Mac users where I work.
My question is - how can I reenable the Java applet plug-in and web start applications via Terminal command? Is this possible? Is there a plist file that can be modified, etc.?
Bob Reed

It is my understanding that Apple's most recent Java update automatically disables Java after a certain period of time that it hasn't been used. We don't want users to have to keep re-enabling it. So we wanted to find a way to do this via script either run by a Casper JSS server or stored locally on each workstation.   With the guidance provided by Mark Jalbert above and some text from a script written by Rich Trouton, I was able to make a script (with some minor changes) and a launch agent to re-run the script upon login. So the preference is always enabled.
For your reference, the script content is:
#!/bin/sh
# DYNAMICALLY SET THE UUID FOR THE BYHOST FILE NAMING
if [[ `ioreg -rd1 -c IOPlatformExpertDevice | grep -i "UUID" | cut -c27-50` == "00000000-0000-1000-8000-" ]]; then
MAC_UUID=`ioreg -rd1 -c IOPlatformExpertDevice | grep -i "UUID" | cut -c51-62 | awk {'print tolower()'}`
elif [[ `ioreg -rd1 -c IOPlatformExpertDevice | grep -i "UUID" | cut -c27-50` != "00000000-0000-1000-8000-" ]]; then
MAC_UUID=`ioreg -rd1 -c IOPlatformExpertDevice | grep -i "UUID" | cut -c27-62`
fi
# Set the the "Enable applet plug-in and Web Start Applications" setting in the Java Preferences for the current user.

I hope this is helpful to anyone wishing to keep the Java web plugin enabled.

No option to Enable the Java applet plug-in and Web Start applications

How do I Enable the Java applet plug-in and Web Start applications
Their is no option under java preferences General Tab
The options i get their are
     Run appelts
          in their own proccess
          Within the browser process
          (Defaut most compatible)
Under the network tab im told
By default java applets and web start applications use network settings in the system network preferences. Only advanced users should modify these settings
Any ideas on why it is like this?

Mac OS 10.6.8
This happend once before when I was running 10.5.8 I fixed it but for the life of me i can't remember how i did it.

What is the Java runtime version required for SAP GUI 6.20 for Windows?

Hi All,

Hardware requirement for Web Dynpro for JAVA

Hi Friends,
I am a starter in Web Dynpro for JAVA and about to develop web dynpro application in JAVA.Can anyone please guide me on the hardware requirement for this application of SAP?
Presently I have ECC 5.0 installed in 1 GB RAM using 160 GB harddisk.
Regards
Ashish.

Hi Ashish,
If you want to install NWDS only then as said 1g.b is sufficient.
But if it's Personal System then you have to install Portal also( WAS).
You will require minimum of 2g.b of RAM and 120g.b of hard disk.

Inconsistent cache location for web start

I have a requirement whereby we are going to use a CD to let the client pre-deploy some of our application jars in the web start cache so that when they access our application online, there is 0 wait time for them.
Fortunately we are supporting only JRE 1.4.2_x and above. After much experimentation with install/un-installing the JRE versions and acessing Sun's web start demos I realized that the java web start
application cache location is different for diferent versions of JRE and Operating systems.
After digging up the JRE 1.4.2_x code found that Sun uses $USER_HOME/Sun/Java/Deployment
/javaws/cache. This seems to be the case on Windows 2000. I tried JRE 1.5 on XP and it stores
it in $USER_HOME/Sun/Java/Deployment/cache/javaws. ( by default) Also the property in deployment.properties file is different
for 1.4.2 it is deployment.javaws.cache.dir
and for JRE 1.5 on xp it is deployment.user.cachedir.
This is making it impossible to write a generic install script for the CD.
Is there a definitive way to know what the cache location is for a given install of the JRE.

first :
version 1.5 also uses the property $deployment.javaws.cache.dir as an override for the property $deployment.user.cachedir/javaws
second, version 1.5 implements a cd install feature, using the "-import" and "-codebase" args.

Widget Foundation: URL for Web Start installation seems to be invalid

Hi,
the URL from the Widget Foundation installation document for the JAVA Web Start installation (http://nvpal168.pal.sap.corp:1080/wfws/foundationWS.jnlp)
can not be resolved. Is the server actually running ? Maybe it is a wrong URL ?
Any help is appreciated
Marcus

Hi Marcus,
Though I have no idea of the internal site, I'll help you install the SAP Widget Foundation on your system.
1) Pls download the Widget Foundation from the downloads section on SDN : https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/webcontent/uuid/d026c9ae-ab33-2a10-70be-dafcd3fc9a82 [original link is broken] [original link is broken].
2) Make sure you have Java 1.6 and above installed on your machine.
3) Extract the Zip file that you downloaded in Step 1. You will find a <b>SAPWidgetFoundation.jar</b> file in it.
4) On the command prompt type <b>java -jar SAPWidgetFoundation.jar</b> and the installer will launch.
Have fun !

Java Signing issues when loading web start app

Hey, not sure if this is the correct place for this - but couldn't think where else to put it...
I'm a bit stuck at the moment and i wondered if anyone could shed some light on my problem, and where I might go from here.
We've developed a EJB3 application that has a web start UI for users to start... The application is developed in Eclipse and compiled and deployed with ant build scripts... When we deploy the application from within Eclipse everything runs smoothly and users are able to start the web start app without any problems... However I've recently tried setting up a Continuous Integration server (Hudson) for us to test new deploys on and for this our build scripts need to be run outside of Eclipse...
This appears to run without a problem, however each time the system is deployed from here the web start application fails to start because web start cannot verify the signing in the client jar
Could not verify signing in resource: http://10.39.216.5:8080/mist2/lib/mist2-client.jarAs far as I can tell from the output of the build everything goes according to plan and there is little difference between the output if the build had been started in eclipse... The only big difference is that when building in Eclipse the build only packs up the compiled code, because Eclipse auto build the application, whereas in Hudson the code is clean built using the ant scripts (which are created by Eclipse)... and if I turn autobuild off eclipse and build the project from scratch using only the build scripts then the same problem arises...
I'm not really an expert on jar signing so I can't really guess at what might cause the verification to fail... any hints would be much appreciated. It feels like there is something that the Eclipse compiler does that is missing from the scripts but I can't think what this might be as the scripts are created in Eclipse
Thanks
Alex

Alex,
I believe your problem might be similar to one I had. According to one forum response (of course I can't find it now), if you have third-party JARs in your application (which in your case would be any eclipse jars), they might already be signed by their originators (as are eclipse jars), which may cause some really strange errors.
The solution for me was to package my third-party (that is, eclipse) jars into their own feature, separate from my application's feature. So, my main jnlp file has an extension to my application's feature jnlp, and that feature's jnlp file has an extension to yet another jnlp file containing the list of third-party (eclipse) jars. Of course, your jar list will probably be different than mine.
Here's all three files. Hope this helps!!

A few questions about signing JARs for Web start

I'm still a bit new to all this, so just want to clear a few things up.
I'm currently trying to publish an application using Web start, so i know I have to sign all the JARs, as it needs to do some writing to the hard drive.
1. I have my main JAR file, and then two "third party" JAR files in the /lib subfolder, I take it I need to sign those two as well, does it matter that I don't have the .class file for those two, as I didn't write them?
2. I'm running the JARSIGNER program with exactly the same command line apart from the filename of the .jar file, is that correct? or do I need a different certificate for each .jar file?
Just can't seem to get all three signed, Web start says one different one isn't signed each time I try it out.
3. When signing, does it add something to the end of the JAR file itself? as I can't see any extra files created.

Signing adds entries in the mainifest, not in the main file list in the jar file.
You can sign third party jar files, but it is not advisable. An alternative is to put third party jars in a seperate extension jnlp file, if they need all-permissions, you can get the third party jars already signed by whoever supplied them. If not, you do not need to request all-permissions in the extension jnlp file, and that part of the code will be run in the secure sandbox.

What are the System Requirements for Web Server hosting Adobe Air application

Working on a project that is using Adobe Air . The Adobe support site has system requirements for the client side application, but for the server side, what are the system requirements?
Using a Windows server, would expect to have approx. 100 concurrent connections at any given time.

Adobe AIR applications are installed on the end user's computer. They are not hosted on a web server. You can deploy an AIR file, which is the installer file for an AIR application, via your web server.

Hardware requirements for web application

I am developing a web application with JSP's and servlets, it also has a database (MySQL) with about 26 tables a few of them with over 40 columns, pictures will also be stored in the Database (uploaded by users), for now the application will not have so many clients but it's intended to grow.
I want to know how to estimate the hardware requirements for both the clients and the server to run the application.
Tanx in advance.

Java 7 Update 21 and Web Start Install Java Extension problem

Hi,
We've been running WebStart with Java 7 update 17 for several months. Late last month we updated to Java 7 update 21. Since this update, we're seeing 14 additional dialogs when the application is launched. Dialogs are Install Java Exception, do you want to install the following software? and then lists a jar file. I've verified that all JAR and JNLP files are signed with a trusted CA.
Has anyone else seen this? Is there away to suppress these additional dialogs?
Thanks,
Terry

I have just found that the use of uppercase/lowercase has changed in 7U21.
We have been running with the codebase notation like this: codebase="http://SERVER:port/folder/file.jnlp" since Java 1.4.2
In 7U21 I get a dialog pr. jar.
If I change to: codebase="http://server:port/folder/file.jnlp " the dialogs are not shown.
