Question about Java plug in problem

Dear Firefox:
My system is Windows XP, Home Edition.
I've been using Firefox browser about 4 years now
and this is the first time I see the following warning on the plug in.
When I checked plug-ins via Tools tab, it says "Java Deployment Toolkit 7.0.450.18 10.45.2.18 is vulnerable. Use with caution". I don't see any way of correcting this 'vulnerability'.
Would you please guide me what this means and what I need to do??
Also, as I was checking all the plug-ins status and for Updates through Firefox page, the banner came up at the top of the page and said "Firefox prevented Java Deployment Toolkit from loading since it's unstable in Firefox".
This makes me very concerned about browsing.
Please help me understand what all this means and guide me with the remedies.
[Q 1] Is something wrong with this Java Toolkit software installed on my PC?
[Q 2] As for other plug-ins listed on the page as "unknown" --- "Research",
what am I supposed to do??
I see several items listed like that.
Most sincerely,
Brauzaa

The Java Deployment Toolkit is used mainly by Java developers who "deploy" Java presentations, few "normal" users ever need that plugin.
See this Blocklist report for that plugin<br />
https://addons.mozilla.org/en-US/firefox/blocked/p428
That plugin has been on the blocklist for a long time. Oracle hasn't done anything to address the insecurities provided by that plugin, so it remains blocked by Mozilla. On the bright side, at least it is a "soft block" do each user can enable it temporarily as they need it for whatever they are doing, but other that doing Java development or using some business applications few users even need that plugin.

Three questions about Java and Ftp

Hello, i've the following questions about Java and Ftp:
1- .netrc file is in $HOME directory but i can't access to this directory from java code. The following line producesan Exception (directory doesn't exists)
FileWriter file = new FileWriter ("$HOME/.netrc");
2- .netrc file must have the following permissions: -rw- --- --- but when i create the .netrc file the following permissions are on default: -rw- r-- r--, how can i change this permissions? (In java code, i can't use chmod.....)
3- Are there any way to pass parameters to a .netrc file? If i get to do this i needn't change the permissions because i can't modify or create/destroy this file.
Thanks in advanced!!!

1- .netrc file is in $HOME directory but i can't
access to this directory from java code. The
following line producesan Exception (directory
doesn't exists)
FileWriter file = new FileWriter ("$HOME/.netrc");$HOME would have to be replaced by a shell, I don't
think you can use it as part of a legal path.
Instead, use System.getProperty("user.home");
Ok, thanks
2- .netrc file must have the followingpermissions:
-rw- --- --- but when i create the .netrc file the
following permissions are on default: -rw- r--r--,
how can i change this permissions? (In java code,i
can't use chmod.....)Yes, you can: Runtime.exec("chmod ...");
I need to use estrictly the .netrc with -rw- --- --- permissions
Yes, i can use Runtime.exec ("chmod ..."); but i don't like very much this solution because is a slow solution, am i right?
3- Are there any way to pass parameters to a.netrc
file? If i get to do this i needn't change the
permissions because i can't modify orcreate/destroy
this file.I don't think so. Why do you need the .netrc file in
Java at all? Writing a GUI frontend?I want to use automatic ftp in a java program and FTP server, the files and path are not always the same, so i can:
- modify .netrc (for me is the complex option)
- destroy and create a new .netrc (is easier but i have permissions problem)
- use .netrc with parameters but i haven't found any help about it
Thanks for your prompt reply!!!!

Question about Java's HttpServer: Threading? Backlog?

Hello,
I have two questions about Java's HttpServer (com.sun.net.httpserver). From the JavaDoc:
>
Management of threads can be done external to this object by providing a Executor object. If none is provided a default implementation is used.
>
How can I get information about the default implementation in 1.6.0_13? Do you know the behavior? From my observations, the default implementation uses no Threads, meaning every request is handled in the same Thread, this results in handling the requests to the HttpServer one after another.
Is this right?
The second question is about this, also from the JavaDoc:
>
When binding to an address and port number, the application can also specify an integer backlog parameter. This represents the maximum number of incoming TCP connections which the system will queue internally. [...]
>
When setting the backlog to -1, it uses the systems default backlog. How can I determine the systems default backlog? Can some lines of Java code reveal it (there is no getBeacklog() method)? Or is it up to the Operating System (we use Redhat Linux)?
Thanks a lot for your help!
Regards,
Timo

How can I determine the systems default backlog?You can't. There is no API for that even at the C level.
Can some lines of Java code reveal itNo.
Or is it up to the Operating System (we use Redhat Linux)?Yes. Linux provides a large default. It seems to be at least 50 on most platforms. This is not something you should be worrying about.

Authentication issue about java plug-in

Hi all:
Since it is a urgent issue and I really need some help,I post the same problem again .Here is my problem description:
I have a website hosted on a Microsoft IIS web server,the web server name is win2003stdbase1.Because of some custom needs,the website must use Kerberos authentication. Other authentication method such as NTLM will fail.The website contains a jar file.
When a client use IE to visit a html page containning a java applet on that site, the java plug-in launches and a dialog box pop up.Here is the Details of the dialog box:
Title: Password Needed - Networking
Server: win2003stdbase1/192.168.0.43
Scheme: ntlm
Use name:
Password:
Domain:
Even I input the right user name and password,the dialog keeps poping ups.
Suspect that the java plug-in use ntlm and it case the authentiaction failure.Can we conifgure the java plug-in to use Kerberos authentication type?And how to do it?
If I did not explain the problem clearly enough,please let me know.
Also any other suggestion about the issue are welcome.

You should always use the latest Java version. Older versions have security vulnerabilities and should not be used. You do not need Java Console extension and they may also not work anyway.

Question about Java Errors

I have some questions about some java errors
1. what kind of errors are contained in Error class?
2.does this class contain only runtime errors?
3. if the question number 2 is positive, what about InstantiationError which is a compile error and is a subclass of Error.
4.When our program is out of memory, which processes are done for an error to be produced. is the error actually from OS or VM?

I have some questions about some java errors
1. what kind of errors are contained in Error class?An Error is a subclass of Throwable that indicates serious problems that a reasonable application should not try to catch.
2.does this class contain only runtime errors?No
3. if the question number 2 is positive, what about
InstantiationError which is a compile error and is a
subclass of Error.
4.When our program is out of memory, which processes
are done for an error to be produced. is the error
actually from OS or VM?Various - both, depending on where the error occurred.

Question about java-based server app frameworks

Hello, I am working on a Java applet application and would like to choose a Java-based scalable server framework to use within my applcation. I have found a few like xsocket or QuickServer and have a question about other. And, also, which is the one You may advise? Yours sincerely, Slawek

For online gaming server. I first heard of xsocket and started using this, but have the problem with NAT. I now know that I need to initiate connections from client behind NAT (server has a public IP) and send messages from server to client within the same connection. I am doing this the following way (as shown in examples- below), but it appears that server receives messages, but client doesnt. I dont listen on any ports in client application and just need to take advantage of the connection initiated (information go from client to server properly).
Server-
try{ nbc = pool.getNonBlockingConnection(inetAddress, 8090);
try{ nbc.write("|01|______|02|______|03|______|04|______|05|______|06|______|07|______|08|______|09|______|10|______"); }catch(Exception ee){}
}catch(java.io.IOException f){}
Client-
public boolean onData(INonBlockingConnection nbc) throws IOException,ClosedChannelException,BufferUnderflowException,MaxReadSizeExceededException{
String x = nbc.readStringByLength(100);
System.out.println("S >> C = "+x);

Some questions about Java deployment steps and techniques

All my java experience is coding and testing in my local machine (where, of course, a jre is available), but ... when I deploy to other people, they may not have a jre or they may have a different version of it than the one needed to run my application. I've read different stuff online including jars and java web start but still I have many questions.
(1) first one first, Sun contradicts common sense, when it says that i can redistribute my own customized light version of their jre by taking out some files (java.sun.com/j2se/1.5.0/jre/README). there are two ways for me to get a jre: Way one is by downloading one from Sun, the download comes as an *.exe file and I don't see how I can take files out of it, so do you know how?. Way two would be by simply copying the set of files i choose (according to that Readme) from my current jre installation (the one on my \java\jdk\jre directory), does this make sense?, (if you're under windows) doesn't an installed version of a jre need a couple of dlls plus some new registry entries?, this contradicts common sense, if I'm not wrong, that Readme is a nonsense, but since that readme is at each of us jre installation \java\jdk1.x\jre\Readme, it can't be a nonsense, therefore I'm wrong, therefore the answer is either Way 1 or Way 2, HOW? ... or maybe there's a Way 3?
(2) Say I never read that Readme so I download the jre (as an exe) to bundle it along with my application in a jar ... now I'll give my neighbor either a jar with two exes or two exes jars ... is there a way to make a jar so that two files get executed? ... if the answer is No and I have competition from a second neighbor, then I believe I'm asking my first neighbor to choose my application based on our friendship, that's not reasonable if we are doing business, so Java loses.
(3) Say that my application is a single executable file like this,
class X{
public static void main(String[]$$$){
System.out.println("Console, where are you?");
At this point, say that my neighbor accepted the two executables, he executed the jre.exe and has jre6 in his system, now he double clicks on my X.jar ... it's a console application and jar files are not associated with the java.exe launcher since java 5, but with javaw which doesn't open any console ... how do i make it so a console opens and prints "Console, where are you?" ... do I ask my neighbor-customer to add a couple of lines to his path and open his console and (please) enter java -jar jarfile.jar? ... isn't it too much? ... i hope i'm wrong cause this is kind of discouraging
(4) I've read that by installing a more recent version of a jre on a system that has an older jre (there to help other applications work), I might be causing a problem for the other applications to run ... I guess that's the reason why that Readme kind of encourage to redistribute a "private" version of a jre (one that doesn't come with a java.exe launcher ... any feedback on this?
(5) I'm reading a lot of hype about Java Web Start ... it looks better than the traditional jar/jre deployment ... but setting up a MIME type to *.jnlp, it doesn't come with some free hosting I've checked ... somebody can recommend a free hosting service that allows to set a *.jnlp MIME? (I'll appreciate a suggestion here, cause I would like to test Web Start)... and, anyhow, how you people compare it with the paradigm of the single executable file?.
Thanks. Your feedback is highly appreciated.

..(5) I'm reading a lot of hype about Java Web Start ... It's gratifying to think that someone who wants to deploy apps., has the common sense to search first! You would not guess how I often I hear "I wanna' make an EXE" shortly followed by "What's webstart?".
...it looks better than the traditional jar/jre deployment ... but setting up a MIME type to .jnlp, it doesn't come with some free hosting I've checked ... OK. You cannot define new mime types, but perhaps the site already has it defined. An easy way to check is to upload 'any old file' that ends in .jnlp and use the [mime type checker|http://pscode.org/mime/] to see what content type it is served as.
..somebody can recommend a free hosting service that allows to set a .jnlp MIME? (I'll appreciate a suggestion here, cause I would like to test Web Start)... I'm pretty sure the Google based sites offer it.

Java Plug-in problems following installation of Oracle 9i

I have been experiencing repeatable problems with the Sun Java Plug-in following installation of Oracle 9i on our servers. Our installation of the Sun JDK 1.3.1_04 or higher seems to conflict with the Oracle installation. Following the install, navigating to any web page that includes an applet reference results in a plug-in error stating that it cannot locate the registry key HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Plug-in\1.3.1_01. The key does exist however for the installed version of the plug-in. ie [HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Plug-in\1.3.1_07]. My only workaround to fix this is to add a new registry key 1.3.1_01 that contains the contents of the registry key for the installed plug-in (for example 1.3.1_07).

The Oracle installation only inlcludes the JRE, which AFAIK isn't referenced outside the ORACLE_HOME directory. The internal JVM couldn't be causing the conflict either. Might be an installer bug of some sort, but not one I have heard of.

Java plug in problem

hello friends.....
...i m using html converter for java plug in ....and tried to convert a jsp page .but jsp still not showing the applet. and there is not any changed occured in jsp file.
please tell me what may be the reason??

ok lemme be more specific abt the question.
There was this class that was compiled using earlier versions of java. I had to make some change to this class and it was only by chance that I had to compile the same class using j2sdk1.4.0. When I try to access the applet from a html page on the client machine it says that the class is not found. And when I install the latest java plug-in, it works fine. I would like to make this applet independent of the plug-in.
I understand from the above replies that I need to compile my class in a lower version of java and make it independent of the plug-in. I would like to know if there is a better way to this.
Thanx for ur time.

Questions about Java Servlets and JSP

Hi,
I'm a confident Java Programmer (and really enjoy using this language) but am very new to Java servlets and Java Server Pages.
I have previously worked with Perl on my web projects (simple 'league' style voting pages). I read in my 'Core Java' book that I should no longer use perl or even cgi.
I need to know more about Java servlets and Java Server Pages so I can make the switch to a 'real' programming language.
I have a few questions:
How should I start to learn JS and JSP?
How applicable will the java knowlegdge I have already be?
Are JSP common on the world wide web?
What tools do I need to start? (I currently develop in JBuilder and have Java 1.4.1 Standard Edition)
Is it likey my web host (and others) will support JSP?
Thank-you very much for helping a novice get started,
Regards,
Paul

Hi, Steve ...has to be frustrating! But do not despair.
Let's suppose the servlet it's named MyServlet on package org.servlets
WEB-INF should look:
WEB-INF
classes
org
servlets
MyServlet.class
web.xml
web.xml file should have this two declarations:
<web-app>
<servlet>
    <servlet-name>MyServlet</servlet-name>
    <servlet-class>org.servlets.MyServlet</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>MyServlet</servlet-name>
    <url-pattern>/MyServlet</url-pattern>
</servlet-mapping>

</web-app>Now, once the container starts (Tomcat?), you should be able to see that servlet in:
http://localhost:8080/[my-context/]MyServletAnd what my-context is? The web application context. This string should be empty if your're deploying to the root context, otherwise should the context name. In Tomcat, deploying to root context defaults to using webapps/ROOT.
Sorry for my English, but I felt the need to answer your request. I hope it helps despite my writing.

Question about Java apps structure

Hello guys,
I'm a professional C++ programmer and I would like to start learning Java. I'm reading about Java from here and there and would like to ask you about how a java program is structured compared to C++.
So in C++, I have main.cpp (or any other file name, doesn't matter), which contains a the main() function, and I have .h and .cpp class files that I instantiate (basically) in my main function to get my program to work.
In Java, I'm confused and can't really find the "general" rule to how stuff are organised. I noticed that every class has a main function (why?), and there's no global scope. And "somehow", file names must exactly be equal to the class names.
The question is: how are Java files of classes (and other stuff, if available) are arranged to create a program? What's the standard why? And How can I have many classes together in a single main()?
Thank you for any efforts :-)

Thank you guys for the replies. I still have some more doubts :-)
Do I have to have a file for the implementation and a file for the definitons, like cpp and header files? or just everything inside the class?
Why does Netbeans fail to compile when I change the class name? what should I change with the class name in general to have it compile correctly? From what I understand till now, the top level class's name (the class with the main() function that's gonna be executed) has to be equal to the file name (and I got that this is the sufficient condition for the app to compile), while the same file can have more classes if I wish. Did I get that right?
I don't know if I get that right too, we pass only a SINGLE class/file to the compiler, and it automatically resolves ALLLL the included files automatically, unlike C++, where all cpp files have to be passed to the compiler/makefile to create object files, and then the executable is created after linking all those object files with the libraries together. i.e.: Java doesn't really need a makefile because making is really simple with only 1 filename. True?

Java Plug-In Problems !!

Hey you guys...I have the OS X 10.6.7 with the updated Java (update 4) and I cannot open any of my works' hospital website links. I keep getting this message
"The Java plug-in is not installed.
The required version: 1.6.0_07".
I've tried different links within the hospital's site and it's a no-go. I went on Mac's OS X Dev. Library to try to figure this out, found this link
http://developer.apple.com/library/mac/technotes/tn2002/tn2110.html#//apple_ref/ doc/uid/DTS10003202
but I don't understand anything that's its saying on how to identify what Java you have. I need to do continuing education for my job, and don't have time during work therefore I need to be able to do this @ home. Please help!!
P.S. It doesn't matter if I use Firefox or Safari, I still get the same message....
P.P.S. Please explain it in very simple terms I'm not very computer savy. Any help/tips would be much appreciated!!

Java Preferences should show:
Java SE 6 Apple Inc. 64-bit 1.6.0.24-b07-334
Java SE 6 Apple Inc. 32-bit 1.6.0.24-b07-334
Also, I was informed that " Runtime environment 5 and 6 are the more common versions required. " I should therefore contact the IT dept.
Lastly, it seems a number of people are having issues using Firefox 4 and running Java, having to reinstall the application a number of times..
Thanks for all your help guys!! Much appreciated!
