Downloading jars during runtime (Applet).

I was wondering if someone could give me some example codes on having an applet downloading a jar file from a remote system and loading the jar contents into memory.
Do you use JarURLConnection with ClassLoader? or is there something else that I can use it with?
Thanks for the help.

Hello,
U can use jar files as Java Extension purposes, just define ur own manifest file for ur jar file. Then define Main-Class & Class-Path parameter inside manifest file. Finally attach ur jar file as an Applet under HTML page.

Problem in referring the methods of jar during runtime in OSB 10gR3

Hi,
I have to use the methods of a certain Jar File. During Development, I import the jar in my OSB Project and refer the methods. But at runtime, I want to remove this jar, place the jar in domain and refer using classpath. when I do this I get error saying classs not found. is there any way to achieve this?

when it's just some generic jar (utility) which is also used by non-osb project, i could imagine you don't want to include it in your osb project and also store it on your classpath somewhere else since you need to maintain it on different locations
but like Manoj said, osb expects the file to be there. as soon as you import it in your osb project it's an osb resource with generated metadata for it. So as soon as you remove it on runtime i could expect the project will be out of sync and will fail.

Specify jar during runtime

I need to use two jar files. However, these two jar files includes some class which have the same name but in slightly different implementation. How could I specify in my code or in the make file which class in which jar file I should use? In addition, one of the class is in the jre jar file. I don't want to use the class in jre (which is default) but the one in another jar file. How do I not use the class default jar file in JRE but in another jar file (I couldn't change this jar file). Thanks.
Stephen

it is easy, import class what you want use.
or driectly define , com.xxx.xxx obj = new com.xxx.xxx();

Security warning in Plugin 1.4.0 during HTTPS applet download

Hi,
I develop a simple applet, which is unsigned beause doens't do critical operation like read or write on client File Systen. But I download it from an HTTPS web server and the certificate installed in the server is created by GlobalSign.
In Plugin 1.3 and previous release, I could download and run my applet from a HTTP or HTTPS site without problem.
In the Plugin 1.4 BEFORE i download my applet, a security warning popup appears, and it inform me that i try to install a "untrusted" cerfificate for HTTPS comunication.
I known that in Java Plugin 1.3 HTTPS connection are managed by Browser and for example in IE the GlobalSign CA certificate is trust, but in Java Plugin 1.4 itself manage the HTTPS connection, and the GlobalSign CA certificate is not present in the default CA trusted certificates.
My costumer is not very "happy" that his costumer see this security warning when download my applet...
So, the question: is it possible to avoid this message in the default plugin 1.4 configuration?
If this is not possible I must use a CA certificate which is trust for Java Plugin, abandoning the GlobalSign certificate.
Best regards
Michele

Here is perhaps a related problem. In IE6 I go to an https mode along with a basic authentication to view a series of private webpages. When I reach the webpage with my applet, I have to autheticate the applet before proceeding. Is the way the Sun Plugin should work? I know the Sun Plugin uses the IE API for server transactions, but in the case of an applet, it must start a new (basic authentication) instance. After the first authentication of the applet, all other applets down the line do not require a username and password.

Error in downloading jars through jnlp from Oracle 10.1.3 App Server

I am working on migrating an application (containing two WARs) from Resin servlet server to Oracle 10.1.3 App Server. The migration was unit tested successfully. One of the WARs was implemented as a web service that downloaded JARs to the client PC through jnlp. When I tried to combine the two WARs into one (application) WAR, some of the JARs failed to download with an error message stating that they were "corrupted". 5 of the 6 "corrupted" contain native code, although two other native code JARs were able to download successfully.
Most of the time the jnlp failure was accompanied with this error: WARNING: Exception returned by remote server: {0}
javax.naming.NoPermissionException: Not allowed to look up java:comp/ServerAdministrator, check the namespace-access tag setting in orion-application.xml for details

Why is the jnlp failing when the WARs are part of the (main) application, but OK when it is part of a web service WAR? How can I overcome this problem?
Thanks for your help.

Hi Marc ,
Thanks for your reply.....
Did you mentioning the script (upgrade_10131_
10133_oracle.sql) in the orabpel. I had run this script after applying the patch.
Still iam facing the same issue.
what need to be done?
Could you please help me on this, because I need to do the Fault Handling Framework in BPEL and so i need the faultpolicy folder to be present.
Since I got the folder by applying the patch, but what happend is when i try to check out for the activity status in the BPEL Console Activity tab it is showing the error as mentioned earlier. Any problem with patch implementation or any bug is there. So far i done the patch installation successfully without error and i upgraded the orabpel schema using the mentioned script also. Any other things i need to do?
Regards,
Ashok.

Accessing a file in the downloaded jar

Is it possible for an applet to access a file in a downloaded jar file?
In other words, the applet class and say a text file are placed in a jar file on the server. Once the jar file is donwload and the applet is started, can the applet read data from the text file in the jar?

This URL should help you solve your problem.

Location of downloaded .jar files?

When I was using the java in the jre package, downloaded .jar files would go to ~/.java I have switched to the openjdk6 package and I have no idea where downloaded .jar files go now... it seems as though they are cached in memory and not saved to disk at all. Are they saved somewhere?

openjdk and jre don't do the same.
openjdk is a jdk (Java Development Kit) and jre is Java Runtime Environment.
And the files should be downloaded into your download directory which you've either set manually or is maybe $HOME/Download.

I need to download the server runtime for BEA WEBLOGIC server

Hi ^^,
I am trying to create a web project in Eclipse WTP europa. I do not have the bea weblogic server installed on my desktop. My organization has issues running it locally. I need to first create a project and then create a war and then deploy it on server.
I am going through the tutorial at the following website:
http://www.eclipse.org/webtools/community/tutorials/BuildJ2EEWebApp/BuildJ2EEWebApp.html
It says "To do this tutorial you will need a server runtime that is supported by WTP"
Also "During web application development, we will need a server runtime environment to test, debug and run our project".
Hence I need the link where I can download the server runtime for bea weblogic server.
T&R,
Prashant

Changing Changing Database Location During Runtime

I'm using Netbeans 6.0.1. My database location ALWAYS change in place. That's why I'm planning that there would be a "Database Settings..." inside my program. But I don't know how to change the current: user, password, url settings of my program DURING RUNTIME. Here's my persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
<persistence-unit name="LibraryPU" transaction-type="RESOURCE_LOCAL">
    <provider>oracle.toplink.essentials.PersistenceProvider</provider>
    <class>desktopapplication2.Books</class>
    <properties>
      <property name="toplink.jdbc.user" value="root"/>
      <property name="toplink.jdbc.password" value="password"/>
      <property name="toplink.jdbc.url" value="jdbc:mysql://localhost:3306/Library"/>
      <property name="toplink.jdbc.driver" value="com.mysql.jdbc.Driver"/>
    </properties>
</persistence-unit>
</persistence>

To solve the "why the hell would I want that stuff inside a jar file" issue, I googled a bit and found this
style of approach in a Oracle forum. Essentially think of the persistence.xml file as an template
that the program uses.
I use a properties file to set all local DB configuration aspects. Load the properties at application
startup and set then extract the required fields into a Map to create the persistent unit.
All the "examples" I seen always use a static xml which is never what you need in the real
world.
Map properties = new HashMap();
properties.put(TopLinkProperties.JDBC_URL, dbProps.getString("abc.jdbcurl") );
properties.put(TopLinkProperties.JDBC_DRIVER, dbProps.getString("abc.jdbcdriver"));
properties.put(TopLinkProperties.JDBC_USER, dbProps.getString("abc.user"));
properties.put(TopLinkProperties.JDBC_PASSWORD, dbProps.getString("abc.password"));
EntityManagerFactory emf = Persistence.createEntityManagerFactory("abcPU", properties);
entityManager = emf.createEntityManager();

Download jar only when it is used

Hello,
I have an applet that uses some jar files, is it possible download the jar file only when it is called by the applet?
Thanks,
Pati

If you add an index file in the first jar file on the
applet's class path, the Java Plug-in downloads jar
file only when necessary.
You can find more information at:

Set Classpath during runtime

How can we set classpath to a .jar file during runtime. Is it possible to set classpath not other than editing a .bat file or by manually editing the global variables list????

You need to implement you own Class Loader if you want to load a jar at runtime. Why would you like to do that in AS?

Captivate Loads Assets During Runtime?

Does a published Captivate project load all assets to the local client before it begins playing, or does it call in assets (like background screen captures) as needed during runtime?
Any info is appreciated!

Thanks for the response, Shekhar!
Let me clarify, maybe I'm using the wrong terms. At some point, the content assets have to reside on the users machine in temp in order to view them - that is what's happening during a site's or a swf's initial load. My question is: does the main captivate file insist that everything within it be downloaded during initial load, or are the separate assets within the project loaded as they are required - as in a background jpg loading only when a given step in a system simulation is reached.
Does that make more sense?

Splitting JARs for faster applet start time

Hi.
I have a remote web client downloading an applet (packaged in a single JAR) from the server.
Problem: JAR file is 3.5MB and takes quite a time to get server->client over dial-ups.
Need: Some way of reducing initial startup time for the applet so the user doesn't have to wait 10min before seeing anything.
Here are the options I see so far...
Option 1
Split the JAR file into smaller JARs, the 'main JAR' has the applet GUI stuff and the 'extension JARs' have the applications launched from applet.
Option 2
Some way of 'dynamically loading' the classes from server either 'as needed' or automatically in the background, after the main applet GUI is loaded.
Option 1 I have tried but it seems that the applet actually does NOT start until ALL the JARs have been downloaded. Which doesn't really help reduce anything.
Option 2 I need a way of implementing?
Any help would be appreciated.

3.5mb jar?????
What you are packing into the file?
You should look into using Java WebStart -- it will download the applet and keep it locally for the subsequent use (doing away with having to keep downloading it).

Including multiple jar files to applet

In one of my application I am using severla third party apis (JavaHelp, JFreeReport, NanoXml ...) which comes as a seperate jar file each.
Is there is a way that I can include these multiple jar files to be downloaded automaticaly when the applet is starting.
currently I am extracting all the jar files and then re compressing them in to one file and place it in the archive property in the applet tab.
Is there a way I can avoid extraction and recompression and directly use the jar files

<param nama="archive" value="myjar.jar, myOtherjar.jar" />
You could try to create an installer that wil put the 3rd party jars in the users lib/ext directory.

Hi, Thanks for that further bug description In Your Last Message That Describes The Problem I Am Having perfectly and is exactly the same for me.
unfortunately that fix for my camera Powershot G6 does not work or apply as the view pictures switch is different on G6 is not usable during download as once you plug in DC/USB cable it turns off, and makes no diff and problem still exists exactly as you just described.
thanks anyways "Selz Boy"
it has been 17 days since apple promised to get back to me within 3-5 days hopefully with a solution, but I have still not heard from them.
They blew me off, i guess, probably i will have to wait for new Yosemite OS update, which they pre-warned me could take as much as 6 months.
I cannot believe apple released this new update with such major bug issues for camera downloads and that horrible "Photos" pgm which has all sorts of downgrades in features, usefulness and new bugs compared to iPhotos which I just finally got used to and was much better software.
I am starting to lose faith in Apple and I am getting that Microsoft "FEEL" like I used to have when I was a PC user, which was why I originally switched to Apple computers in first place.
Oh well got my fingers crossed here.
Thankfully the memory card reader solution is working well, but cost me $45.
