Start using Java 7 in JDeveloper

Hi,
I'm using the lastest JDeveloper and this might be a silly question, but how can i set it up to start compiling using Java 7 sdk? I tried preference but it doesn't have it there.
Also, i'm guessing i need to do the same for my weblogic.
-Marvin

After installing Java 1.7.0 I got "Unsupported JDK version" message during JDeveloper 11g startup. No choice to select any other version of Java with this screen at all. So you have to say "Yes" to "Continue anyway?"question to get started IDE.
That's the story: I had uninstalled Java 1.6.0_26 after installing 1.7.0, so I installed it again. Then I've added Java 1.6.0_26 by using JDeveloper "Tools-Manage Libraries" feature to "Java Definitions - Libraries - User" successfully. Still I got the same message while starting up..
Well, should I re-install JDeveloper to fix this or any other idea?
p.s. I have many screenshots related to above story, but I cannot share through this forum unfortunately.

Application started using Java Web Start doesn't launch the first time

The first time the application is installed using a link on the browser it's downloaded then the certificate dialog is shown, after that I check the checkbox to accept the certificate permanently. The application doesn't load, it only loads the second time although I see it in the task manager. If I don't accept the certificate permanently it does load. This happens on both Firefox 2 and IE 7. I enabled the console and logging but nothing shows up there.That's really a weird problem, I wonder if Java Web Start is a viable deployment option, it does have great capabilities such as autoupdate but still seems to have important bugs.
Does anyone have any clue about what is going on.
The problem doesn't occur on Ubuntu 7.10.

You were right my XML file was not correct. I still couldn't find a valid JNLP validator. Sun has to provide that.>No they don't (have to supply a validator for their own document type, though it makes sense to do so), but yes they do (provide a tool that validates XML against schemas). Java can validate XML against a DTD or XSD.
Check these two threads (and chase the links) for more details.
JNLP xsd schema
<http://groups.google.com.au/group/comp.lang.java.programmer/browse_thread/thread/c6f65bf1df5f105d/30c6b7e2dc342dc4>

Look especially for the posts by Piotr Kobzda.
I had a tool on my site based largely on Piotr's codes, that linked to a valid JNLP DTD and XSD, but unfortunately my site is offline at the moment. Andy assures me that the JNLP 6.0 DTD has been corrected for the developer ..download tutorials of web start, though the online (web site) version may still be invalid.

Deployment Issues using Java Web Start

I am attempting to deploy a Java application that works in JDeveloper. The app has a Database connection to a MSSQL 2000 Server which is loaded into the active Project Libraries as Other JBDC. When I deploy the app using Java Web Start I receive the following error: com.microsoft.jdbc.sqlserver.SqlServerDriver.
How to I need to configure my deployment so the JDBC works properly? Thanks in advance

I got it to work with the following settings:
1. edit ur ctbuild.xml file to have these settings:
<include name="BC4J/lib/msbase.jar"/>
<include name="BC4J/lib/mssqlserver.jar"/>
<include name="BC4J/lib/msutil.jar"/>
Then have the same jar files in localmt.jsp as

<jar href="adfjars/BC4J/lib/mssqlserver.jar" />
<jar href="adfjars/BC4J/lib/msutil.jar" />
2. edit data-sources.xml file, if ur using external oc4j as
<data-source

Unable to run my application using java web start

i have created one application and use java web start to download the application. all the files are succesfully downloaded but when i try to run the application an expected error occur. this only happen in my machine but not in other machine i'm currently using
-jsdk1.4.2
-windows 2000 professional 5.00.2195 service pack 3
-pentium III 870 Mhz
-x86-based PC
-RAM 256 Mhz
Anyone knows why, plz help me with this puzzle

Please post the information from the Web Start "Exception" and "Wrapped Exception" tabs when the error occurs (I assume the error was in fact unexpected ;-)
A blind stab in the dark would be that you don't have write permission to the cache directory on the second machine. Also worth checking that the proxy settings on the second machine are the same as the first (if they are on the same network).

Cannot acess file on server from client machine using java web start

Hi everyone,
I am creating an appication using JWS and Apache Web Server version 2.0.54 on Linux. I am trying to access a file on the server that IS NOT inside the jar file. I have given full access (r, w, x) to all users on my server. We also created a FilePermission object and gave the file read and write access as well. But when we deploy the program and try to get this file, a SecurityException is thrown with the following mesage:
acess denied (java.io.FilePermission filename read) where filename is the file in our local filesystem. Any suggestions on what I can do?
Any help would be greatly appreciated.
Thanks,
Raj

It sounds like you are trying to access the file as if your JNLP application were running on the server. The JNLP app is running on the client machine, so you will need to use a URL to open the file. Take a look at the JavaDocs for the following:
     java.net.URL
     java.net.URI
     java.net.File
You also need to be sure your server is configured to serve the file. For example, you ought to be able to access the file through your browser using something like http://www.myco.com/myapp/myfile.txt. (How you configure your server is a topic for a different forum.)
You probably also want to look into JavaWS security, and even Java security in general to determine if you need to sign your app or not. Here are some links to get you started:

JVM - Microsoft JScript.dll Memory Leak when using Java Web Start

I have posted before a topic related to this matter, although now I have a lot more information about what is going on (although still no fix for it). This is the link to the earlier post, containing JVM HOTSPOT EXCEPTION_ACCESS_VIOLATION
http://forum.java.sun.com/thread.jspa?threadID=5116970&messageID=9402346#9402346
The issue is that after deploying on Windows XP a multi threaded, memory consuming (40 Mb) Java Swing application using Java Web Start, and the standard web page (IE6) reference to the jnlp file to launch the installation from Tomcat, each time this application gets executed by double clicking on the desktop icon (with no IE6 interaction at all), calls start being made between jvm.dll (sun) and jscript.dll (Microsoft IE), these interactions never release the memory they consume, so after a period of using the application it crashes unavoidably. If I execute exactly the same application launching it from command line (no Web Start nor IE6 browser involved), the application works nicely all the time, no problem at all.
My question is: does anyone know why these calls to jscript.dll are even being made during web start application execution? As said, it's a desktop Swing app, it does not need the browser at all, and jscript.dll is a IE dll. Anyone can advice on how these interactions can be eliminated?
I've worked with Microsoft support for two weeks on this issue and all they have said is that it is a Sun problem and they can not help further.
Thanks
Jes�s

Microsoft suggested (among others) two test.
1- Install IE7 and run the application
2-Install Firefox and run the application
Results were:
For 1: The application does not crash, apparently IE7 has a newer version of Jscript.dll that, in Microsoft words, handles better 'bad software', refering to 'bad software' to the java virtual machine I guess. Looking at the performance manager you can see memory goes down as with IE6, but at some point memory is released and the app. does not crash. Anyway is still is uncertain to me why Jscript.dll is getting involved at all. Although this solves the problem is not a viable solution for us, because I work in a corporation where changes such as upgrading the IE version on a large number of desktop can not be justified just because one app. is crashing, and it would take a long validation time anyway before the upgrade can proceed.
For 2: I did install Firefox in a machine and the application still crashed, but it is true I did not uninstall IE6, so the conflictive Jscript.dll was still sitting at system32. Quite possibly the crash would not happen if that dll wasn't there at all.
Thanks

Custom classloader fails when using Java Web Start

Hope you can help me with a problem that is driving me nuts. I have implemented my own classloader to support plugins. This classloader works as follows:
1. The classloader is configured to access a plugin components jar file downloaded by jws.
2. The plugin components jar file contains other jar files which contains the actual plugin code to be loaded using my own classloader.
3. Upon initialization - my classloader extracts all jar files contained in the plugin components jar file into temporary files.
4. These temporary files are used by my classloader when defining plugin classes.
The classloader works fine when not using java web start. Then I launch the application using java web start with security policy in .jnlp file set to:
<security>
<all-permissions/>
</security>
After a while (it was able to load some of the classes) it fails with the following stack-trace:
Regards,
Terje

Does anyone have source code for implementing a simple class loader that can be used with Java Web Start (preferrably with all jar files to be used by the classloader wrapped into a jar file)

If you implement your own classloader, and then still run with a SecurityManager installed, then your ClossLoader is responsible for asigning the permissions to the code it loads.
You need your ClassLoader to extend SecureClassLoader, and implement the method :
SecureClassLoader.getPermissions(CodeSource cs) to return the PermissionCollection you want.

Dynamic JNLP - displaying using java web start

Hi,
I am creating a dynamic JNLP in a servlet at the server side. Please see below.
String someJnlpString = "<?xml version=\"1.0\" encoding=\"UTF-8\"?> \n" +
                                            "<jnlp .....    >    </jnlp>";
        String attachment = "inline; filename=\"launch.jnlp";
        String ct = "application/x-java-jnlp-file";
        OutputStreamWriter out = new OutputStreamWriter(response.getOutputStream());
        response.setContentType(ct);
        response.setHeader("Cache-Control", "max-age=30");
        response.setHeader("Content-disposition", attachment);
        out.write(someJnlpString);{code}
Then in my JSP, I am trying to open this JNLP by using the following code
{code}        window.open('servlet/DisplayImage?arg=first-arg");The exception that I am getting is JNLParseException could not parse launch file. Error at line 0. If I open the downloaded file then its working.
Can somebody please advise me how can I directly open that JNLP from the servlet by using java web start?
Thanks a ton,

I am able to run it now after clearing the java cache

Problem with CORBA application deployed using Java Web Start 1_6_0.

Java Web Start fans and experts:
We have been using Java Web Start to deploy the client side of a CORBA-based application since the inception of Java Web Start ... including Java Web Start 1.0 right up through the present.
With Java Web Start 1_6_0, we see evidence that Web Start is "tinkering with" the IOR that CORBA uses to communicate. In all previous versions of Java Web Start, independent of the JRE which the application uses, the stringified IOR have been the same size regardless of whether the application is deployed locally or via Java Web Start. With Java Web Start 1_6_0, the stringified IOR is much longer than the "real" IOR (again, regardless of the JRE used by the application itself). To me this smells like a bug in Java Web Start 1_6_0. Has anyone else observed this behavior?
Here are some specifics .... I've run the same client application with various JREs both with and without Java Web Start as the deployment mechanism. The application was compiled and runs against servers that are running JDK 1_5_0_09.
Here is the summary of my results from a Linux box running various JREs, various versions of Java Web Start, and also running as a non-JWS deployed application. I've listed the length of the stringified IOR in each case.
JRE 1.5.0 non-JWS client: stringified IOR length = 344
JRE 1.6.0 non-JWS client: stringified IOR length = 344 ... this, I think, excludes the JRE as the cause of these problems.
Java WS 1.5.0, JRE 1.5.0 JWS client: stringified IOR length = 344
Java WS 1.5.0, JRE 1.6.0 JWS client: stringified IOR length = 344
Java WS 1.6.0, JRE 1.6.0 JWS client: stringified IOR length = 1568
Java WS 1.6.0, JRE 1.5.0 JWS cleint: stringified IOR length = 1568
In all cases, the stringified IOR length is determined by the service receiving the message and is always running JRE 1_5_9_09 and is
always the same 344 characters in length UNLESS it was deployed
using Java Web Start 1_6_0, in which case it in nearly 5 times as big!
To me, it sure looks as if there is a problem with Java Web Start 1_6_0 to be adding so much to the stringified IOR. Note: it's hard to tell how different the underlying IOR is in the JWS 1_6_0 case because, unlike most other ORBs, the Sun ORB doesn't have a tool to extract the IOR into a human readable structure. However, I can think of no good reason why the identical application deployed using Java Web Start 1_6_0 should have a stringified IOR length that is different than that of the same application deployed in non-JWS form or should differ from the behavior seen in all previous releases of Java Web Start.
Any clues or suggestions? Has anyone else observed this behavior?
Thanks,
John

lol. That's one way to start.
But really, why would you want to start an ftp server from java?? You should use the right tool for whatever job you need to accomplish and you can set up windows to automatically start the server when it boots.

But if you insist, you'll probably need JNI.
