How can we pass argument to static block of code????

hi ,
My question is we can use static initialization block for having functionality like constructors for initializing static variable ,but we cannot pass arguments to static initialization block then how can I create functionality like parametrized constructors.Whats the alternative shall I use a static method to perform this functionality,since all methods in given class are static and
there is no need of creating instance of class.

Hello Jussi,Salut Jérôme
That's probably a more maintenable design.
However what do you base your remark on - I'm struck by the word obviously?
Is there some design principle from which this advice so naturally ensues that it is obvious ?Yes I read my posting later on and thought about changing it, since it's not necessarily an obvious solution. I was making assumptions that I didn't clarify from the OP.
In the OP's case, the "state" on which those methods operate is apparently fixed, presumably at the beginning of the program, so what's wrong with all this staticness?
I can list:
- threading issues (a non-issue after some initialization phase), that you wouldn't have with immutable instances
- harder unit-testing (that's not an OO design problem, more a methodology problem)
- mix and confusion between static and non-static state if the class ever happens to have both, in future maintenance. All good points, I see all-static classes as a "code smell" and especially in this case when there's parametrization involved.
Now we just need to have the OP explain his situation a bit better.

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.

How can I pass arguments from one MIDlet to another MIDlet

Hi everybody !
Can anybody help me in knowing that how can I pass the parameters from one
MIDlets to another one in same application.
I am devloping a application in which I am using more than two MIDlet and I
want to transfer Parameter from one MIDlet to another one.
I just explain what I have done....
I made a MIDlet "A" and "B" in the same project using NetBeans IDE.
In MIDlet "A" I create the Object of MIDlet "B" so that the constructor of
MIDlet "B" is called and parameter can be transferred.
But when I run the program it shows me two MIDlet on the screen, that I
doesn't need.
Suggestion are most welcome....
Thanks in advance
Regards
Bhagwat

If you create two MIDlet in a midlet suite, it will display as you mentioned means you can't change the display style.

How shall i send user data to servlet by an Applet in way Form does

it is clear that URL class provides way to connect to remote web resource. and furthermore i am trying to make an applet perform like a Form in html to send user data to a servlet. i may adhere a long name-value string to url sent by applet but this is not a good way to hide information like hidden variables. Is there any class in J2SE package that i can wrap those Form data and send them in the way Form does...?
cheers!

It's not a matter of form vs. not-form, it's a matter of HTTP types.
Basically HTTP allows a connection to be of various types: GET, POST, HEAD, and some lesser used ones like DELETE which many servers won't support anyway. GET is usually used for link clicks, and puts its arguments as name/value pairs as part of the resource name. POST sends it as body data, also as name/value pairs.
In Java, the way you do this is, starting with your URL object, get an HttpURLConnection object. Then call setRequestMethod on that HttpURLConnection object. If I recall correctly the rest is basically the same.
Check the docs for details and stuff I may have forgotten or got wrong. Also check RFC 2616, which is the HTTP specification.

How do I pass arguments to a TestStand sequence from an operator interface written in LabWindows?

I intend to use TS_EngineNewExecution() which takes a VARIANT parameter for the arguments.
I have only found example code for C++ where a propertyObject containing the arguments is converted to a VARIANT using the constructor of the _variant_t class.
How do I accomplish this in LabWindows?

Hi webprofile,
I did not extensively test this code, but based on the previous posts, this is what the function might look like (I bolded the changes from what ships by default):
TERetval Eng_BeginSeqExecution(tSeqFileRec *seqFileRec, // must NOT be NULL

How can we pass the control from servlet to portlet ?

Hi,
we use PortletRequestDispatcher.include method to call the servlet.
In my servlet, I have the following form information.
out.println("<form method=\"post\" action=\"http://abc 40acce5.3a.com/portal/dt?display=Command\">");
out.println("Enter value: ");
out.println("<input type=\"text\" name=\"UserName\" value=\"\">");
out.println("<center> "); out.println("<input type=\"submit\" value=\"Go Back Portlet\"> ");
out.println("</center> ");
out.println("</form>");
When user click the submit button, the servlet will go to portlet first, then go to another page.
is the url (action="http://abc40acce5.3a.com/portal/dt?display=Command) correct ?
if not, what url we should use ?
Can you help ?
Thanks!

Oh I thought that you have selection-screen and again you are working on dialog programming.
if you want to use select-option directly in module pool then it is not possible.
but you can do other way.
create two varaiables
data : v_kun_low like kna1-kunnr,
v_kun_high like kna1-kunnr.
use these two variables in layout ,let user knows that he can not give options like gt,lt,eq ,it will be always BT.
and also when you see normal report program,you can use multiple values in either low or high,but here it is not possibel.
use can enter only low value and high value.
when you come to program point of view
declare one range
ranges r_kunnr for kna1-kunnr.
do the coding like
r_kunnr-low = v_kun_low.
r_kunnr-high = v_kun_high.
r_kunnr-options = 'BT'.
r_kunnr-sign = 'I'.
append r_kunnr.
now you can use r_kunnr in select query ,it will work like select-option.
other than this there is no option.
Thanks

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

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,

Passing arguments with spaces through to asc.jar

According to the docs, we can pass arguments through to llc using -fllvm-llc-opt. Additionally, with llc we can pass arguments through to asc.jar using -ascopt. Let's say I want to define an AS3 variable in my flascc swf/swc. asc.jar says that I can do this using "-config <ns::name=value>".
So it seems like I should be able to do this:
gcc ... -fllvm-llc-opt=-ascopt=-config CONFIG::RELEASE=true
But this doesn't work, as the "-config" parameter takes its next argument via a space and not an equals, which throws the whole thing off. gcc thinks its another argument. Trying it with spaces like this:
gcc ... "-fllvm-llc-opt=-ascopt=-config CONFIG::RELEASE=true"
also doesn't work. The toolchain outputs:
Error:
LLVM ERROR: Failed to run /usr/bin/java with args:
-Xmx1500M -jar /Users/asimmons/FlasCC_1.0/sdk/usr/bin/../../usr/lib/asc2.jar -merge -md -abcfuture -AS3

As you can see, the "-config" command made it to asc.jar. What I think is happening is that its being passed to asc.jar as one argument (not two). For example, I can copy-paste this command into bash and it will work-- just not when done from gcc.
So: how do I pass arguments with spaces through to asc.jar?

I believe you should be able to do this by splitting it across two fllvm-llc-opt flags:
gcc ... -fllvm-llc-opt=-ascopt=-config -fllvm-llc-opt=-ascopt=CONFIG::release=true
The Makefile in the 12_Stage3D sample that ships with the FlasCC SDK demonstrates this.

Passing arguments to the jsx file from command line

Thanks for taking my question.
I am using the following to be able to run my script from the command line.In case you were wondering on why i would be doing this- i would need to invoke the javascript from a server side code(like java,php etc. in my case it is java)
"c:\Program Files\Adobe\Adobe Utilities\ExtendScript Toolkit\ExtendScript Toolkit.exe" "c:\path to script\myscript.jsx"
Anyways, i have been successful in running the myscript.jsx from the command line but i am not able to figure out how i could pass arguments to "myscript.jsx" from the command line, and be able to refer to these arguments within the script.
I have tried the following
"c:\Program Files\Adobe\Adobe Utilities\ExtendScript Toolkit\ExtendScript Toolkit.exe" "c:\path to script\myscript.jsx" "argument1" "argument2"
and tried to refer these arguments within the script using arguments[0] and arguments[1] . But looks like this does not work.
Any thoughts?????

To run JavaScript from the prompt using ExtendScript Toolkit 1.0.3 or 2.0.2 you need to do the following:
Add the line #target indesign to the top of your script otherwise ESTK will open without executing the script. Example:
#target indesign
//MakeDocumentWithParameters.jsx
//An InDesign CS2 JavaScript
//Shows how to use the parameters of the document.open method.
//The first parameter (showingWindow) controls the visibility of the
//document. Hidden documents are not minimized, and will not appear until
//you add a new window to the document. The second parameter (documentPreset)
//specifies the document preset to use. The following line assumes that
//you have a document preset named "Flyer" on your system.
var myDocument = app.documents.add(true, app.documentPresets.item("Flyer"));
//SaveDocumentAs.jsx
//An InDesign CS2 JavaScript
//If the active document has not been saved (ever), save it.
if(app.activeDocument.saved == false){
//If you do not provide a file name, InDesign will display the Save dialog box.
app.activeDocument.save(new File("/c/temp/myTestDocument.indd"));
Ensure Indesign is open. Execute the following command:
"C:\Program Files\Adobe\Adobe Utilities\ExtendScript Toolkit\ExtendScript Toolkit.exe" -run "[path to script]\script.jsx"
For example:
"C:\Program Files\Adobe\Adobe Utilities\ExtendScript Toolkit\ExtendScript Toolkit.exe" -run "C:\Program Files\Adobe\Adobe InDesign CS2\Presets\Scripts\test.jsx"
This command can be easily called from Java or any other third party application of your choice.
It took me a while to find this information, so I thought I'd share it with everyone.
Good luck!

How can i pass more than 1 param to servlet to show blob image

Hi
my servlet expects 2 param to SELECt an image from a blob column
public class ImageBlobServlet extends HttpServlet {
private static final String CONTENT_TYPE = "text/html; charset=windows-1252";
public void init(ServletConfig config) throws ServletException {
super.init(config);
public void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
response.setContentType(CONTENT_TYPE);
String ImageId = request.getParameter("id");
String TipImg = request.getParameter("tip");
OutputStream os = response.getOutputStream();
Connection conn = null;
try {
Context ctx;
ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("java:/comp/env/jdbc/rhDS");
conn = ds.getConnection();
PreparedStatement statement = conn.prepareStatement("select FIT from " +
"RHH_FOTOS IMG " +
"where IMG.IDASSO = ? and IMG.TIM_COA = ?");
statement.setInt(1, new Integer(ImageId));
statement.setString(2, TipImg);
To display the image i tried to use:
<af:image id="ot1"
*source="/imageblobservlet?id=#{bindings.Con.inputValue}?tip=#{"EMP"}"*
shortDesc="Foto"/>
but i receive all content in the get of first param.
String ImageId = request.getParameter("id");
How can i pass one more then 1 param in EL.
Thanks in advance

Hello,
seems to me you're using wrong separator for the second param into your URL:
<af:image id="ot1" source="/imageblobservlet?id=#{bindings.Con.inputValue}
tip=#{"EMP"}" shortDesc="Foto"/>
I think it should be:
<af:image id="ot1" source="/imageblobservlet?id=#{bindings.Con.inputValue}
tip=#{"EMP"}" shortDesc="Foto"/>

How to pass arguments to a batch file from java code

Hi
I have a batch file (marcxml.bat) which has the following excerpt :
@echo off
if x==%1x goto howto

I'm calling this batch file from a java code with the following line of code:
Process p = Runtime.getRuntime().exec("cmd /c start C:/Downloads/Marcxml/marcxml.bat");
so ,that invokes the batch file.Till that point its ok.
since the batch file accpets arguments(%1 %2 %3) how do i pass those arguments to the batch file from my code ...???
%1 is a classname : for ex: gov.loc.marcxml.MARC21slim2MARC
%2 is the name of the input file for ex : C:/Downloads/Marcxml/source.xml
%3 is the name of the output file for ex: C:/Downloads/Marcxml/target.mrc
could someone help me...
if i include these parameters too along with the above line of code i.e
Process p = Runtime.getRuntime().exec("cmd /c start C:/Downloads/Marcxml/marcxml.bat gov.loc.marcxml.MARC21slim2MARC C:\\Downloads\\Marcxml\\source.xml C:\\Downloads\\Marcxml\\target.mrc") ;
I get the following error :

1 - create a java class (Executer.java) for example:
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
public class Executer {
     public static void main(String[] args) {
          try {
               for (int i = 0; i < args.length; i++) {
                    System.out.println(args);
               Class<?> c = Class.forName(args[0]);
               Class[] argTypes = new Class[] { String[].class };
               Method main = c.getDeclaredMethod("main", argTypes);
               // String[] mainArgs = Arrays.copyOfRange(args, 1, args.length); //JDK 6
               //jdk <6
               String[] mainArgs = new String[args.length - 1];
               for (int i = 0; i < mainArgs.length; i++) {
                    mainArgs[i] = args[i + 1];
               main.invoke(null, (Object) mainArgs);
               // production code should handle these exceptions more gracefully
          } catch (ClassNotFoundException x) {
               x.printStackTrace();

               x.printStackTrace();
          } catch (Exception e) {
               e.printStackTrace();
2 - create a .bat file:
@echo off
java -cp C:\Downloads\Marcxml\marc4j.jar; C:\Downloads\Marcxml\marcxml.jar; Executer %TARGET_CLASS% %IN_FILE% %OUT_FILE%3 - use set command to pass variable:
Open MS-DOS, and type the following:
set TARGET_CLASS=MyTargetClass
set IN_FILE=in.txt
set OUT_FILE=out.txt
Then run your .bat file (in the same ms dos window)

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 many variables to servlet using a URL? Ajax related.

I have 100 text boxes in my JSP and want to pass the values stored in these text boxes to a servlet with out the need for submitting the entire page using AJAX frame work.
I know how to peform the above in ajax if I have only 1 textbox. But how can I do that with 100 text boxes. I don't want to build a huge URL with 100 parameters.
I am thinking may be create an array and send it to the servlet, but don't have an idea if we can do it.
Please help me .

You can make a POST request using an XMLHttpRequest, but you won't be "passing many variables using a URL", which seems to be one of your requirements, and which makes your question confounding(after all how do you pass many variables using a URL without putting many variables in the URL):
req.open("POST", url, true)
req.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
req.send("first=Eric&last=Kaiser");
