WebStart and Metrics

My group supports a Java application which we'd like to add "auto-update" functionality to. We have a rough implementation now where we place a version text file on our web server and the software compares this with its own version to determine if an update is available. Then, if the user downloads the update, the application sends certain user information which is collected for metrics then provides the updated JAR.
We'd like to do better, and Web Start looks like it might help... but... It's not entirely obvious how we'd still be able to collect metrics if Java Web Start is managing the downloading and installing of the application. Is there a way for an application, installed via Web Start, to send information to a server-side script before running the normal Web Start stuff?
TIA

I think the best way to do this is to use a servlet to handle all the requests for the jnlp file and jar files of the application. You could modify the JnlpDownloadServlet (source found in the sample directory of the JDK) to record the ip address and frequency of Head Requests for the jnlp file . Assuming the jnlp file contains an href parameter, and no <offline-allowed> tag, Java Web Start will make at least one Head request for the jnlp file each time the application is run.
The servlet (w/o modification) would also give you the capability to do JNLP version-based downloading, jardiff updating of jnlp files, and pack-200 based downloading.

WebStart and JavaMail -- unable to relay

Hi
I have an application that I can run from the command line that can successfully send email using JavaMail.
I package the app up for WebStart and run it on the same machine, when I send the mail using JavaMail I get a 550 error:
class com.sun.mail.smtp.SMTPAddressFailedException: 550 5.7.1 Unable to relay for [email protected];Any ideas? My mail.jar and activation.jar are specified in my JNLP file for my app as an extension (as they are signed already)...
Has anyone seen this?
Thx,
Mark

er no
I run my app from a command shell on XP and sendimg mail via our Exchange server works fine on my development machine.
I run the SAME app using a WebStart based installation on the same machine as per the command shell run, with the installation downloaded from a webserver on the same machine and when the piece of code that sends a mail is invoked I get the UNable to relay error..
Why would it work from the command shell and not from WebStart...

Webstart and Javassist Custom Classloader

Hi,
I have an application that makes use of javassist for code modification, which I wish to deploy with javaws. This application works fine under eclipse, but under JNLP my class loader is circumvented and most of the classes are loaded with the JNLP class loader .
The loader is below. My problem is that when I load the class 'Example' I can see from messages printed out in my translator that this class is definitely loaded through the javassist loader, but when I then print out the classloader for the Example class, the result is the JNLP class loader! I believe this is the root of the problem, as all further classes loaded from the main class will then use the JNLP class loader?
So it this a security feature and how do I work around this? Is there anything else I need to do to be able to use javassist with a JNLP appliction?
Any help much appreciated!
Cheers,
Adriaan
public static void main(String[] args) {
     try {
          Translator t = new DelegateTranslator();
          ClassPool pool = ClassPool.getDefault();
          final Loader cl = new Loader(MyLoader.class.getClassLoader(), pool);
          cl.addTranslator(pool, t);
          Thread.currentThread().setContextClassLoader(cl);
          Class<?> c = cl.loadClass("Example");
          System.out.println("Classloader is "+ c.getClassLoader());
          cl.run(args[0], newArgs);
     } catch (Throwable ex) {
          ex.printStackTrace();
}

Well, we gave up on trying to make this work. Instead we wrote a Maven task to statically translate the code after compilation, so that we do not need javassist in webstart anymore. This is based on the maven task from the JBoss Seam project (thanks, JBoss!). I had never written a Maven task before, so it was very helpful to have an example. A link to the code for the maven task is [http://viewvc.jboss.org/cgi-bin/viewvc.cgi/seam/maven-plugins/trunk/seam-instrument-wicket/]. This solved the problem for us.

Multiple network adapters and metric settings

I can't seem to get Windows to use the preferred wired adapter over the wireless. I have set a manual metric value to each adapter and it shows correctly in the route table but that doesn't seem to matter. Its still always defaulting to using
the wireless adapter. I changed the order in the advanced settings on Manage network connections as well but nether seem to work.

My LAN is connected to a router that makes a connection to my office. The wifi is connected to my home wifi.
So if I connected to something in the office and then turn on the wifi i get immediately disconnected and can't get back in until i turn off the wifi. I can also run nslookup and with the wifi turned on it always goes to the wifi router. I use
the wifi to access a shared storage i use with other computers in my house.
At one time this did work with this setup but last week i swapped out my drive for a larger one and re installed windows, hasn't worked since.

Hi,
As this setup did work at one time, so I think all settings you made is right, according to your description, the issue happened after you reinstall Windows, the system might lose some important updates, I suggest you check for updates, and keep all important
updates. Meanwhile, please reinstsall the network adapter driver as a test, it's recommended to look for the driver in the manufacture website.

ICR Reporting and Metrics

We have implemented process 003 for a few months now and it seems to be working quite well (thanks to the help of Ralph of course). I am charged with a new task. Upper management is demanding metrics proving the improvement of our I/C reconciliation process from this tool and want metrics that shows counts and dollar values of matched vs unmatched per document type for every company. I did a quick SE16 for just the last period on table FBICRC003A in order to possibly extract the items and use Group # to identify matched since this table also had document type and the number of entries was over a million. It would not be efficient to pull this for every period and try to analyze the data this way. Is the standard functionality or any suggestions on how to accomplish reporting?

Hello Staci,
You could check whether the required information is contained in the line item report (FBICRC00DDATALIST) or totals report (FBICRC00_TDATA_LIST). Other than that you can use all SL reporting tools like report writer/painter, drilldown reporting and extraction to BW.
If using the line items reporting is not an option (runtime?) you could also add field DOCTY in an append to tables FBICRC003C and FBICRC003T. Then you would need to delete and recalculate the totals data for the periods you are interested in. Afterwards you could run your reporting based on FBICRC00*_TDATA_LIST. Assigned documents will have RTYPE = 2 and unassigned documents are RTYPE = 1.
Hope this helps,
Ralph

WebStart and application parameters

Ok, please forgive me if I'm being stupid.
I saw the question on the JWS Unoffical FAQ but the answer is worded pretty oddly and I'm left a bit confused. ("You can add parameters as follows ... However, WebStart will then bomb badly, " etc) -- I need to pass parameters to my application. They don't really need to by dynamic (or, I can handle it through other means, anyway) -- I just need a way to specify parameters through the JNLP file. Is there an easy way to do this? (It seems like there ought to be ..)
Thanks,

One (easy) way is to use properties, as explained in http://java.sun.com/products/javawebstart/faq.html#41

Help with jars webstart and InputStream

I am currently attempting to fix all the things that break
the minute you attempt to use a jar under webstart.
I have attempted to find an answer by searching the forums.
I cannot determine how to overcome the following.
I have third party jars for "Jasper reports" and the loadReport
function requires a java.io.InputStream as input.
"public static JasperReport loadReport(java.io.InputStream inputStream) throws JRException"
The report templates are in my jar file in a sub directory "\sreports".
I was loading the template with the following code.
JasperReport template = JasperManager.loadReport(new FileInputStream(reportFile));
Where
String reportFile = ".\\sreports\\Std"+tableName+".jasper";
I have tried several things including below.
FileInputStream fs = new FileInputStream(getClass().getResource("sreports/StdEquipmentType.jasper"));
which does not even complile.
Rykk

Get your input stream like:
InputStream in = getClass().getResourceAsStream("path/to/file.txt");
note that you use "/" and not "\" or "\\" no matter what OS you are using.

Different versions of Java webstart and Java Runtime Environment

Hi I am using a thin application client (swings application) which is downloaded as a jar file using Java Web Start. The earlier version of the application was deployed on the server and client using the version 1.5.0_09. Due to some performance measures we are changing the Client version of JRE to 1.6.0_03. Will this really help??
The approach we are following is bit confusing.
First we are launching the application in JRE 1.5.0_09 and creating a shortcut for that (WebStart shortcut). Later we are changing the Java Web Start version from 1.5.0_09 to 1.6.0_03 in the shortcut.
And of course also changing the JNLP j2se version tag to 1.6
The application we are launching using this shortcut but its throwing FailedDownloadException : Unable to Load Resource hxxp://ascdcf.....*.jnlp
The funny thing is when i launched the same shortcut using the 1.5.0_09 version i.e. only the WebStart version as 1.5.0_09 and the JRE on client as 1.6.0_03 the application starts.
I searched about this and came to know that webstart just deploys the application jar on the client in a browser independent form and then it is run on JRE. If thats the case (and if i am right) then Webstart version can be anything only the JRE version should be the latest as specified in the JNLP. Can anyone give me suggestions in this regard???
Also if this approach is correct where will we get more performance???
1. Is it running application on updated JRE Version i.e. 1.6.0_03
2. Or on updating Java Web Start i.e. 1.6.0_03 (curretnly which is not running)
Also the Java Web Start is a part of JRE then where does this lead to....???
I am just an amateur with great doubts.....kindly help......

Mac webstart and java 1.4

hello,
i am having trouble with using an app designed for java 1.4 on the mac with webstart. Basically it works fine when launching from the JNLP, but when the user creates a desktop icon for it, the mac wants to run java 1.3 instead, thereby failing. it basically sits there catatonic for a while and the exception is tossed to the console, so it is very bewildering behavior.
is there a workaround for this (other than making the app work on both 1.3 and 1.4)?
thanks,
james

this happens for an app i wrote, too, only all of the macs worked fine on java 1.3. then they all upgraded to 1.4, then the only way they can run the apps is thru the webstart console. anyone have any recommendations?

Time Config and Metric Refreshes

Post Author: owen
CA Forum: Performance Management and Dashboards
I have a daily calendar setup for the finnacial year 01/04/08 to 31/03/09 set up in Time Config.
When setting up my metrics i selected the option to stop at current period, which only gives values up to yesterday.
Taking off the stop at current period creates values up until 31/03/2009, most of which are blank. When these are displayed in IMT's etc you get all the blanks on the report and a little bit of data for the beginning of the year. A complete purge and refresh needs to be done to get new values each day.
Does anyone know of a way of getting it to run up to and including today?

Post Author: jezbraker
CA Forum: Performance Management and Dashboards
The idea is that until the period actually ends why would you want to refresh the metric - and thats why it defaults to stop at the last completed period rather than "current".To get around this you need to play about with the "stop metric calculation" part and use the rules engine to mess with the CI_PROBE table.You create your daily metric with Stop at Current Period turned off and set a fixed end date to allow the metric to refresh "today". when you refresh, it will back fill and obviously refresh until today. Thats great but of course if you click refresh tomorrow nothing will happen.So what you then do is schedule rule to refresh a metric refresh daily at the desired time, and add an action before the metric refresh action that uses the Execute sql action. in this you connect up to the EPM repository tables (all the CI_* stuff) and update the CI_PROBE table by adding a day to the stop field... think its called end_date - or possible stop_date...I recall doing something similar for a customer that wanted a metric to be refreshed every hour (hence overwriting the last hours value and only sotring the value of the last hour of the day in the metric history) obviously EPM isnt designed to work houry but using freesql rules did the job. The other option is to mess about with the servers clock of course - but thats a bit hacky for most

Java WebStart and JacORB!

Hi All,
When running the application from command line using -Xbootclasspath
works fine, but when started from webstart, I am getting method not found exception. I was able to initialize the ORB properly(used ORBClass, and ORBSingleton options). Basically this is happening because of loading Sun's ORB instead of JacORB. Looked at this forum and applied setContextLoader() tip, but it didn't help.
I am using Java Web Start 1.4.2_02, and 1.4.2 Java.
Any Help is appreciated.
Thanks,
Sanjay.

Hi,
I am using jacorb with NO problems.
I load a signed jacorb.jar as an extension:
<jar href="lib/jacorb.jar" />
Then,
before calling orb.init, y load jacorb.properties as a resource from another .jar, and put it in a Properties object.
Properties prop = new Properties();
InputStream bis= null;
try {
bis = getFileJar(fileNamePropertiesJacorb);
prop.load(bis);
for (Enumeration e = prop.keys(); e.hasMoreElements(); ) {
     Object key = e.nextElement();
     String valor = prop.getProperty(key.toString());
     prop.put(key.toString(), valor);
Then, I initialize the ORB:
orb = org.omg.CORBA.ORB.init(args, prop);
Make sure these properties exists in your jacorb.properties file:
org.omg.CORBA.ORBClass=org.jacorb.orb.ORB and
org.omg.CORBA.ORBSingletonClass=org.jacorb.orb.ORBSingleton
Hope this helps.
Any doubt, ask me.

If someone run into similar problems: include openejb-client.jar and geronimo-ejb_.3.0_spec_1.0.1.jar into the jar file of the web start client (I used FatJar for building) instead of just referencing to them. After this it will work as expected.

Webstart and using different JRE's

Hi,
I have a few questions about Webstart.
1) When will webstart support JRE version 1.4 ? (at the moment if i create jnlp application and specify the required runtime to be j2se=1.4 I get an error because webstart can't find that JRE on the sun website, even though i already have the 1.4 JRE installed and have configured webstart to use it)
2) Is it possible to tell webstart to use a non Sun JRE ( like an IBM JRE ) ?
Keith Bishop

Hi,
I have a few questions about Webstart.
2) Is it possible to tell webstart to use a non Sun
JRE ( like an IBM JRE ) ?
Yes, we are using an IBM JRE with Webstart.
Currently we have a jnlp process that runs before our application jnlp process that basically rewrites the javaws.cfg file to configure jws to use only the ibm jre which our application requires.
I am looking into moving that same process within the installer extension of our application. The challenge will be to see if while running our application via jws, reconfigure jws to use the ibm jre and have everything work ok. I don't yet know if this will work.

Opportunity and metrics calculations used in reports

Hi,
Need to know how various entities are being calculated in the Opportunity and revenue matrices.
Eg:- what's the formula being used to calculate Avg. Sales Cycle and Avg. Days in Stage etc.
Any suggestions will be helpful.
Thanks
Nakul

Hi Nakul,
I know that for the Sales Stage report that each night when the ETL runs it takes a snap shot of the opportunities and what sales stage they are in (etc), and the Avg. Days in Stage is based off all the snapshots for how many days a opportunity was in a sales stage.
I’m sorry though I don’t know what the formula’s are that are actually used to figure out 2 two metrics you asked about.
Hope this helps.

Webstart and ResourceBundle (Do sun engineers test at all?)

http://developer.java.sun.com/developer/bugParade/bugs/4891531.html
Are they ever gonna fix that? It's been almost a year since the bug was reported but nothing has happened!?
It's about the internalization of java applications! I don't know how big a procent of java developers are from outside the US (>75% probably) and sun is basically ignoring them with this &#"�%#� bug. Please, for next version do some actual testing on locale detection code before releasing it. And do it fast.
As if the ResourceBundle isn't buggy enough try to use it together with webstart. Everything about internalization breaks. Webstarts classloader loses all resourcebundles and you stuck with en_US. If the app is run from the commandline you can actually get the bundle with correct locale but with webstart you never know what's going to break next.
Since it's introduction the webstart has been one of the most promising innovations but it has stayed as that. It's a promise, nothing more. Does it actually update the changed jar files for your app? Answer: Most of the time, if you lucky. Well one can always implement a version check between server and client and tell the user that sorry: you need to manually flush the webstart cache since it doesn't want to download the changed version of the jar file.
I don't know to which forum this rant belongs, but I'm sick of spending most of my coding time with creating workaround to java bugs.
-- end of Rant.

not much consolation but in the keynote speech one of the top brass at sun said that java was now fast enough and that attention would turn to stability
