How to create command line java client

I have a java servlet FileClient.java and am invoking it thru POST method from the html file. How can I create command line java client so that I can execute this class file from windows command prompt.
e.g. java FileClient <argument>
TIA

> .. there's also a "won't work".
I could post a sample...I know that you can instantiate and call aservlet,
or even write your own servlet container - butit's
still a local instance. He can't invoke his remote
servlet by calling its class on the client like he
suggested.HttpURLConnection in main.Only if his Servlet has a main method. Which wouldn't really make it a servlet anymore.
OP said he wants to invoke it from command-line using
java -cp . TheServletClass
He said he has a servlet called FileClient. And he can't invoke a servlet directly that way, without building a wrapper that starts it, making it more than a servlet, and it definitely won't execute on the server. That's my whole point. I never wanted to say you can't write a command-line program that invokes a servlet on a remote server. I do it myself after all.
I guess I should have expressed myself more clearly.

How to create a custom java client Security Policy File?

I have a stand-alone java client which invokes a .NET WSE 3.0 enabled web service. The web service SOAP header requires username token to be passed from my java client.
Could some one kindly provide a sample of a client-side Security Policy File?
Your help is very much appreciated.
Mike

This is still a workaround...
But if you put checks on all your forms to see if the user has accepted the terms (assumes there is an attribute tracking this) then you can redirect the user to the terms/conditions forms. Still not spoof-proof, but it would be bookmark proof. (and a pain if you have too many forms)

How to run ADF command-line test-client on standalone weblogic host

I have followed the steps to create a test client for the ADF application. In used the following link:
http://download.oracle.com/docs/cd/B31017_01/web.1013/b25947/bcquerying007.htm
The above link does not talk about how to setup the environment where the standalone weblogic is installed to be able to run the test client.
I can run it in the jdeveloper environment.
I can also run from the command line on the development host, by cut-paste the command from the jdeveloper output log tab.
I am trying to run this client on the machine where we have a weblogic installed (standalone) for testing. We can run our ADF application from the browser with no issues. We want to automate and run some testing related to the ADF model (non-viewcontroller part) from the command line on this test stage.
Which/Where are the ADF libraries?
How can I add our application jar deployed on the weblogic (ear file) to the CLASSPATH?
What other libraries ADF/Weblogic do I need for the command line test client?
What am I missing?
Thanks for any help.

How to give command line arguments

does anyone help me out in how to give command line arguments after run my program
m using netbeans6.0.1

If you want your program to take console input while it's running (as opposed to command line arguments, which are passed once, when you start your program), you can wrap a BufferdInputStream or a Scanner around System.in.

Creating a simple java client for a session EJB local interface

Hi all
Is it possible to create a simple java client for a session ejb local interface with JDeveloper.
The problem is that it creates a test client for a remote interface only...
i.e.
MySessionEJB sessionEJB = context.lookup("MySessionEJB")
and once i try to adjust it manually for the local interface...
MySessionEJBLocal sessionEJB = (MySessionEJBLocal) context.lookup("MySessionEJBLocal") (MySessionEJBLocal - is the name of my local interface)
it generates the exception:
javax.naming.NotFoundException: SessionEJBLocal not found
at...........................(RMIClientContext.java:52)
There is still no problem with accessing the local interface object from the jsf project where i've added <ejb-local-ref> tag into the web.xml file.
but i need the possibility of testing the simple java client for the local interface to test business methods wich should return objects without indirect properties
Thanks in advance.
Alex.

Pedja thanks for reply.
I still dont understand what is wrong with my example.
The first peace of the code i wrote (getting the reference to the remote interface object) works pretty well, and even more it is produced automatically by JDeveloper, so why we cant get a reference to the local interface object the same way?
Certanly we should use the local interface for getting access to the resource functioning under the same local jvm and i think it doesnt metter wich app server we really use wls or oas or others
Thanks. Alex.

How to Pass Command line arguments to an exe created in LV8.0

Hi Friends,
I have Created an exe in LV8.0, which accepts the Folder path as input and executes.
I want to call this exe passing the parameter (i.e folder path in my case) from the command line argument. How to pass arguments to the exe ?
Generally we may be having different types of input parameters to a vi like numeric control, string, boolean etc..If we create an exe that needs three input parameters among which one is boolean, other is string and third is a numeric value.
How to pass these different types of input controls to the exe as parameters in command line at the same time?
Thanks and Regards,
SODLB

I don't have any experience with the 8.x application builder, but the 7.x one has a checkbox for passing the arguments to the executable.
As for reading them, there should be an example in the example finder (Help>>Find Examples) which shows how to do this. If you want to pass multiple parameters, I suggest you use a structure similar to NAME=VALUE, so that you can parse each element to find the = and then use a case structure to decide what to do with the parameters. This allows your users to enter or not enter any of the switches.
Try to take over the world!

How to execute command line by Java

Hi all,
I have the following DOS command line that I need to execute it through Java:
C:\Documents and Settings\Mxmler\Desktop\bin>vr1tovr2 Box.wrl -o Box2.wrl
I know that I have to use Runtime.getRuntime().exec, But can anyone show me how to use it for the above?
Thanks

Mxmler wrote:
I need your help please
Forget about the first thread
vr1tovr2 located inside a sub directory called converted (not in the main directory of the project constructed by eclipse)You have to tell the system where to find the program you're trying to run. You can specify the full path to the executable. Alternatively, you can specify the PATH environment variable when you call exec() (and I presume there's something similar for java.lang.ProcessBuilder). Read the docs.
Box.wrl & Box2.wrl (will be generated) both of them are located in another directory called usrYou can either specify full paths to those files, or you can set the current working directory when you call exec(). So you'd tell exec() that you're in the directory where those files are. Read the docs.
I have tried to do the following and I got the following error message: CreateProcess error=2, The system cannot find the file specifiedYou need to do what I said above, in particular, the first one (where you tell the system where to find the program you're trying to run).
String path = System.getProperty("user.dir");
String userFolder = "usr";
String fileName = "mxmler";
String extension = ".wrl";
Runtime.getRuntime().exec("vr1tovr2 "
            + Key.QUOTE
            + path

            + Key.FORWARD_SLASH
            + fileName + "v2" + extension
            + Key.QUOTE);If you're going to break it down like that, then don't use the version of exec() that takes a single String for the whole command line. Use the version of exec() that takes an array of Strings (the first String in the array is the program to run, and the remaining strings in the array are arguments to that program).

How to pass command line arguments to Web Start appclient?

Hi,
I would like to pass arguments to appclient, but "javaws" unable to do that.
Do I have to overwrite the JNLP? I use Sun Appserver 9.0, it creates JNLP on the fly!!!
Please help, thanx!
MB

Hi, MB.
If you are talking about the automatic Java Web Start support for launching app clients in GlassFish, you can pass the equivalent of command line arguments using the query string of the URL you use to launch the app client.
Briefly, use
http://host:port/client-path?arg=first-arg&arg=second-arg& ...
specifying the argument values in the order that you want them passed to the client.
The GlassFish server will do the right thing and generates the correct JNLP so your arguments are passed to the app client.
The GlassFish developer's guide http://glassfish.dev.java.net/nonav/javaee5/docs/AS91DG.pdf discusses this and all aspects of the Java Web Start support. You can also take a look at this blog entry http://blogs.sun.com/quinn/entry/command_line_arguments_and_properties that focuses on how to pass arguments.
Since this technique deals with argument passing in the URL, it works no matter how you launch the app client: a URL in a browser, the javaws command, etc.

Executeing Command Line Java

Greetings, I need to execute the following command line in
java (and get the results via CF):
java -cp
/Volumes/htdocs/encrypt/me/;../bcprov-jdk14-133.jar;.;
com.me.crypt.Do test
I have tried to do this with cfexecute but I cant seem to use
the arguments attribute correctly. I have even tried this but all I
ever get back is a blank string:
<cfexecute name="java" arguments="-version" timeout="100"
variable="MyObj" />
Im also not sure how to create a object with
the"../bcprov-jdk14-133.jar" in there. Normally I would just put
the classes in the classpath and create a object but the jar is
throwing things off. Its not my java class and Im not really at
liberty to change it.

When you provide the name of the class, it has to include its full package name (your's doesn't have a package) and the parent directory of the root of the package has to be on the claspath. In your case: java -cp Java Simple It works in the first case because if there's no classpath specified and no env var set, then the classpath is assumed to be the current directory.
