RMI Codebase Passing Arguments

I'm new to RMI and Java.How do you pass arguments using serialization in RMI? I'll be passing the arguments from a servlet. for example if i want to pass a string object from a servlet to the calling client service. Thanks

Can you please provide me with a better direction in terms of developments (i.e examples)? thank you

Problems with passing arguments to app

Hi.
I have a litle problem with passing arguments. I create a dynamic jnlp file using jsp. This is my code:
<%
response.setContentType("application/x-java-jnlp-file");
String l = request.getParameter("login");
String p = request.getParameter("pass");
out.println("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
out.println("<jnlp spec=\"1.0+\" codebase=\"http://212.244.104.27:8080/PzP_INSTALL/\" href=\"pzp.jsp\">");
out.println("<information>");
out.println("<title>xxx</title>");

Hello again.
Thanks for your replay but unfortunetly it doesnt work too :-(
I've tried to use the out.println statemants in the servlet instead of using a jsp page but the error is the same. Please look at my code and tell me if you can what could be wrong.

How to run a java class from a shell script with passing arguments

hi,
I have a jar with all the required classes. I was using ant to run the classes i needed.
But now i want to use a shell script to run the class, also the class accepts some arguments so when script is run it should accept arguments.
So can any one tell me how to set class paths, jar location and call the required class from shell script or batch file with passing arguments to it.
Thanks in advance.

Let's say that the order of arguments is as below
1. Jar file name
2. Classpath
Your shell script would look like this
java -cp $CLASSPATH:$2 -jar $1 I am assuming that your jar file has the required main-class entry in its manifest. Note that $1...$9 represent the arguments to this shell script.
The same goes for a batch file
java -cp %CLASSPATH%;%2 -jar %1

How to pass argument to the Java Plugin JVM w/o using the Control Panel?

I want to deploy an applet to be loaded by the Java Plug In
and fix some settings of its Java Virtual Machine.
The JPI Control Panel offers two ways to pass arguments to the JVM,
none satisfactory.
1. while interactive via the Control Panel Window.
This cannot be a solution for a deployed applet.
or
2. by editing the system generated file that stores
the settings of the Plugin Control Panel, using a property
named javaplugin.jre.params.
The problem with this method is that if forces to access
and edit this property file which is stored at various locations
depending the client platform. Then, it may collide with other
settings for other applets.
Is there a way to pass the arguments to the JVM
from within the html file?
Has anyone found a solution to this question?
JPS

I am interested in this issue as well.
Did anyone find a reliable way to specify the runtime parameters that should be used by the Java Plug-in in order to execute a given Java applet?
I believe a good place to specify these runtime parameters would be the applet's JAR manifest: only digitally signed applets should be able to set the desired runtime parameters...
Any comments / suggestion would be greatly appreciated.
Regards,
Marco.

How to pass argument in manifest file

Hi,
I want to pass argument to main class in jar. Is there any option in manifest file.

Hmm..
Seems that my sentence above isn't so correct.
It possible to add custom attribute: value pairs into manifest file and
read it later from Java class.
Here is code sample:
public class ManifestTest {
    public static void main(String[] args) {
        try {
            java.util.jar.JarFile jar = new java.util.jar.JarFile(System.getProperty("java.class.path"));
            for (java.util.Iterator it = jar.getManifest().getMainAttributes().keySet().iterator();it.hasNext();) {
                Object curKey = it.next();
                System.out.println("key: " + curKey + ", value: " + jar.getManifest().getMainAttributes().get(curKey));
        } catch (Throwable t) {
            System.out.println("exception occured: " + t);
}

How can I pass arguments to a TestStand sequence with LabWindows 6 ?

Hi
I have created sequences in a TestStand file.
I want to program a sequence with Labwindows 6 which would call all these existing sequences (containing parameters).
I don't have any problems to create the steps "SequenceCall" but i don't know how to pass arguments to the sequences with the TS API.
I have used the look-up strings "TS.SData.SFPath", "TS.SData.SeqName", "TS.SData.ThreadOpt" to program the sequence file / sequence and the multithread option. But now how to program the arguments passing ? I think there is something with the lookup string "ST.SData.ActualArgs"...
Thank u very much for any help

I'm not sure if you want to pass values from TestStand to LabWindows or if you want to pass values in TestStand from a sequence call step to a called sequence.
To get TestStand variables from LabWIndows, use the following function:
tsErrChk (TS_PropertyGetValNumber(testData->seqContextCVI, &errorInfo, "Locals.StartPoint", 0, &dStartPt));
iStartPt = (int)dStartPt;
The TS_PropertyGetValNumber gets the TestStand variable Locals.StartPoint and puts it into the LabWindows variable called dStartPoint. Numbers to and from Test Stand are always a double type. The next line converts it to an integer.
To put a LabWindows value to TestStand, use TS_PropertyPutValNumber.
To pass values from a sequence call step to a called sequence, create variables in the Parameters t
ab on your main sequence. Create same variables on the Parameters tab of the called sequence. In main, specify module to be called in calling step. There is a paramters section on the Edit Sequence Call dialog box which appears. Check the Use Prototype of the Selected Sequence box. You can then list all the parameter variables in the parameters section.
Hope this is what you want.

Creating pocess intance of a different process and passing arguments

Creating Process instance of a different process:
I have two different process: Main_Flow (id: MainFlow) and Second_Flow (id: SecondFlow). In the first process I am reading a csv file. Each line of the file has four columns. After reading each line I have to initiate Second_Flow and pass the read data from the file. (Pls find the code below for the whole process):
     fileReader = FileReader(arg1 : fullFileName);//filename is of file type and have file name and path
     Java.Io.BufferedReader reader = BufferedReader(arg1 : fileReader);
     String str;
     int countLines = 0;
     while ((str = reader.readLine()) != null)
          strColumn = str.split(delim : ",");
               int ColumnCnt = 0;
               while (ColumnCnt < 4)
                    //defining variables
                    String appNo;
                    String custNo;
                    String loanAmm;
                    String loanDate;
                    //logMessage("Value at Column: " + ColumnCnt + " is " + strColumn[ColumnCnt]);
                    if (ColumnCnt == 0)
                         arrLoanData["appNo"] = strColumn[ColumnCnt];
                    else if (ColumnCnt == 1)
                         arrLoanData["custNo"] = strColumn[ColumnCnt];
                    else if (ColumnCnt == 2)
                         arrLoanData["loanAmm"] = strColumn[ColumnCnt];
                    else if (ColumnCnt == 3)
                         arrLoanData["loanDate"] = strColumn[ColumnCnt];
                    arrLoanData["descriptionArg"] = "AutoInstance: " + formatTime('now', timeStyle : Time.SHORT);
                    arrLoanData["genByArg"] = "Automatic";
                    ProcessInstance.create(processId : "/SecondFlow", arguments : arrLoanData, argumentsSetName : "BeginIn");
                    ColumnCnt = ColumnCnt + 1;
          countLines = countLines + 1;
(“The code is in Java and not in PBL”)
I have to pass appNo, custNo, loanAmm and loanDate as the arguments. The Argument will be of Any[String] type. The argument set name of Second_Flow is “BeginIn”. But I am not getting anything in Second_Flow.
What can I do in the argument mapping of begin of Second_Flow to get the passed argument (array)?

the argument 'arguments' for the method ProcessInstance.create receives a map of the arguments that the 'argumentSetName' argument set will receive.
so for example if your second flow has 2 arguments, String name, Decimal value and String[] content your method invocation would be:
ProcessInstance.create(processId : "/SecondFlow", arguments : {"name": strNameFromCsv, "value": valueFromCsv, "content": ["a","b","c","d"]}, argumentsSetName : "BeginIn");

How to pass argument in main function ?

How to pass arguments in main function of one class from another class ?
I don't want to pass argument from command prompt.
I want to try something like this -
class Test{
public static void main(String args[]){
for(int i=0;i<args.length;i++)
     System.out.println(args);
class Fun{
public static void main(String args[]){
     Test t=new Test("Hello","good bye");
when i run Fun class it gives error.
Suggest me how can i do that.

In Fun class main method does not take arguments that is fine. In Test class instead of main method you can have constructor to take input parameters as suggested by BalusC
However, if you want to make your existing code work, you can call (though not appropriate) main() method of Test class from main() method of Fun class (As main() method is static object is not required to invoke this):
Test.main(new String[]{"Hello","good bye"});Here is your code:
class Test{
public static void main(String args[]){
for(int i=0;i<args.length;i++)
System.out.println(args);
public class Fun{
public static void main(String args[]){
//Test t=new Test("Hello","good bye");
Test.main(new String[]{"Hello","good bye"});
} Thanks,

Passing arguments to a custom component in the constructor

I would like to know if it is possible to pass arguments to a
custom component in the constructor when I'm instantiating it
within Actionscript. I've not seen anyone do this, so at the moment
I have a couple of public properties defined on the custom
component and then do the following:
var myComponent:TestComponent = new TestComponent();
myComponent.propertyOne = true;
myComponent.propertyTwo = 12;
etc.
Whereas I'd like to do something like:
var myComponent:TestComponent = new TestComponent( true, 12
Any ideas if this is possible?

Another approach as opposed to creating init function is to link symbol with autogenerated class (just assign it a class but do not create *.as file for it) and use it just as graphical view with no functionality (well only MovieClip's functionality).
ViewClip.as
public class ViewClip extends MovieClip {
    public var view:MovieClip;
    public function ViewClip(){
        this.view = instantiateView();
        this.addChild(view);
    protected function instantiateView():MovieClip {
        return new MovieClip();
Circle.as
public class Circle extends ViewClip {
    public function Circle(scaleX:Number, scaleY:Number) {
        super();
    override protected function instantiateView():MovieClip {
        return new ClassView();

Pass arguments to JSF tag attributes like id oder value

Hi!
I started with JSF some weeks ago and have some questions that i could not find in FAQ or tutorials.
My page structure uses some <jsp:includes>. Each included page uses JSF.
The structure is (example - users):
Users.jsp
|
|(incl)
|
Mainpage.jsp (=Framework)
|
|(incl)
|
Browser.jsp (=Table)
In "Users" all specific data is set. In "Browser" there is a <h:form> tag and a <h:dataTable> tag.
The result should be a simple table with users inside.
So I want to pass arguments to those sub-pages.
1) -> form-ids as parameter:
<h:form id="#{sessionScope.formName}">
... does not work, because ids have to start with a character or "_".
formName is set as followed:
session.setAttribute("formName", "form_users");
2) ->beans as parameter:
<h:dataTable id="browser_table_#{sessionScope.id}" styleClass="browser_table"
var="user" value="#{sessionScope.user_list}">
... does not work. "id" is requested to be a static value and "value" can't find the bean by this string.
user_list is set as followed:
session.setAttribute("user_list", "UserListBean.users");
(UserListBean.users is an ArrayList)
Is there an error in my thinking? Or is there a way to pass arguments as i want?
Thanks!

sorry ... mistake in topic: "oder" = "or" of course :)

Passing arguments to VBScript Program Object - Without WScript.Arguments?

I am trying to create a program object with a VBScript that will change the name of a PDF created by a scheduled report. I need to be able to tack on the string "OH_2010_Qtr_1" (or whatever state - OH is used as an example) before the file extension - the VBScript creates that string based on the date the report is run. I want to be able to pass parameters to this script but when I try to do so I get the error "Variable is undefined 'WScript'" when trying to run the program object. I tried creating a batch file that would pass in the parameters and I get a generic error.
How can I pass arguments to my VBScript? The arguments are necessary because this is for multiple instances of the same report, run for different states.

For VBScript Program Objects, some injected objects:
For Each arg in Script.Args
' Do something interesting with String arg here
Script.Writeln(arg) ' Output to stdout
Next
and
' Get InfoStore
Set infoStore = Session.Service("", "InfoStore")
Sincerely,
Ted Ueda

Problem passing arguments with air.swf

I'm attempting to launch my AIR application using
launchApplication() in air.swf. I'm having problems passing
arguments to my application due to what appears to be some
restriction in allowed characters. To get around this, I've even
tried URL encoding and Base-64 encoding my arguments to make them
more friendly, but it's still failing:
Error: Invalid argument: PG5vIGlkZW50aWZpZXI+
at AIR$/escapeArguments()
at AIR/launchApplication()
at
adlm_launcher/onDownloadClick()[E:\adlm\launcher\src\adlm_launcher.mxml:181]
It seems that any kind of punctuation is not allowed in
arguments. URL encoding them doesn't work either because the % is
rejected. Is there any other way around this?

Yes; it's a security restriction. Browser invocation require
process creation, and many process creation APIs giving special
meanings to certain characters. Letting those characters through
has in the past been a source of security vulnerabilities. While we
also try to avoid using APIs with this behavior, extra layers of
defense are also good.
I think + and / may actually be safe choices; you make a good
point that they're useful for Base64. If you could submit a feature
request at www.adobe.com/go/wish, we'll definitely consider it.
Another option, btw, is to use the LocalConnection API to
pass data between the web page and your application once your app
is launched. LocalConnection has fewer restrictions on the data
passed.
