Trying to convert VBScript to Java

I want to change this VB Script into Java for use in
Dreamweaver
<% If rsCalendarDetails("images") <> "" Then
%>
<img
src="images/calendarphotos<%=(rsCalendarDetails.Fields
.Item("images").Value)%>">
<% Else %>
<images src="images/calendarphotos/nopix.gif">
<% End If %>Thanks for anyone who can convert this to a Java
script for me. I am a designer first, programming
novice....Okay first of all Java and JavaScript are not the same things. But as that code does database access I would say that you do in fact mean Java.
Probably JSP or servlets. But what you have posted isn't nearly enough information because you will have to convert everything including the bits where you connect to the datasource and execute your query.
You should probably go somewhere where you can pay someone to write this for you. It probably won't cost you much for a straight conversion (which may not be ideal but apparently is what you want).

Trying to convert String to java.sql.Date

I need to convert a String (in the format "yyyy-mm-dd") to java.sql.Date
It was suggested I use the following,
SimpleDateFormat formater = new SimpleDateFormat("yyyy-mm-dd");
Date result = formater.parse(dbirth.getText());
However, It seem to produce a java.util.Date
Error: found java.util.Date
Required : java.sql.Date
Can anyone help?
Thanks, Marika

Converting XML to Java in STB

I am trying to convert xml to java. Looking for simple and light way to covert xml to java in STB.

Heh - all the tags in your question got stripped out by the forum-to-email bridge :-)
Anyway, basically you just parse the XML data. You can use some
kind of library if you like, but it turns out that parsing an XML response
that's consistently formatted the same way isn't all that hard to do directly.
In the HD cookbook project, we have a sample xlet that does just this, reading
weather data from some public web service out there (I forget which - maybe
Yahoo's?) The xlet could be converted to work on MHP or OCAP without
much work. This demo is in xlets/demos/weatherWidget, and the project
is at http://hdcookbook.com, click on the sumo wrestler. It's in the source-code repository,
but over on the right one of the links will let you browse individual files, which should
get you pretty quickly to the XML parser in this demo.
By the way, if you have a choice between JSON and XML in this environment, I'd
personally go with JSON. It's simpler to parse and faster - indeed, see
com.hdcookbook.grin.util.JsonIO in the cookbook repository. Of course, if you're
interacting with a server under your control and you want maximum performance, you
can use a more efficient binary format, too.
Cheers,

Converting this VBScript into Java???

HI
I hava found this VBSCript. But I like to work on java.Is it possible to convert this into java code. Basically the script runs something in the remote machine. If its possible ,would u pls tell me what special package I need ??
call execprog ("217.138.120.34","c:\acad_deploy\AdminImage\install.bat")
sub ExecProg(ServerName, ProgramName)
'     dim process as object, processid as long, result as long
     set process=getobject("WinMgmts:{impersonationLevel=Impersonate, authenticationLevel=pktPrivacy}\\" & servername & "\root\cimv2:Win32_Process")
     result=process.create(programname, null, null, processid)
     if result=0 then
         msgbox "Command executed successfully on remote machine"
     else
         msgbox "Some error, could not execute command"
     end if
end sub Thanks in advance

I hava found this VBSCript. But I like to work on
java.Is it possible to convert this into java code.Yes, it is possible to convert the VBScript program in to Java code. You need to identify what the program (script) does and what the other programs are doing as well. (You said the VBscript calls other programs on remote machines). After this, design a way to implement same functionality with Java.
Basically the script runs something in the remote
machine.What "something"?
If its possible ,would u pls tell me what
special package I need ??It is possible, in order to convert the VBScript program to Java, you will have to create a Java package to contain the class hiearchy, i.e. com.admin.install.*
And of course you will need packages from J2SE and possibly J2EE. The Runtime and Process classes from J2SE are examples what is available. These objects can be used to used to call the other programs. Your design will depend on details of the other programs.
Do you plan on converting the "install.ba" program to Java as well?

Problem converting a (working) Java program into an applet

When I'm trying to access an Image through a call to :
mediaTracker = new MediaTracker(this);
backGroundImage = getImage(getDocumentBase(), "background.gif");
mediaTracker.addImage(backGroundImage, 0);
I'm getting a nullPointerException as a result of the call to getDocumentBase() :
C:\Chantier\Java\BallsApplet
AppletViewer testBallsApplet.htmljava.lang.NullPointerException

It seems very weird to me... :-/
(all the .gif files are in the same directory than the .class files)
The problem appears with AppletViewer trying to open an HTML file
containing :
<HTML>
<APPLET CODE="Balls.class" WIDTH=300 HEIGHT=211>
</APPLET>
</HTML>
(I tried unsuccessfully the CODEBASE and ARCHIVE attributes, with and without putting the .gif and .class into a .jar file)
I can't find the solution by myself, so, I'd be very glad if someone could help
me with this... Thank you very much in advance ! :-)

Thanks for your help...

Sorry,
Can you tell me how do you solve it because I have got the same problem.
Can you indicate me the topic where did you find solution.
Thank in advance.

Error: could not be converted to [class java.lang.Class].

I am newbie to JDeveloper (10.1.2) on winxp and i was trying to setup the example from the following url http://radio.weblogs.com/0129487/2003/09/19.html
It is a how to on "Executing Toplink Queries using JavaBean DataControl "
Any help would be greatly appreciated.
Near the bottom on step "In StrutsPageFlow diagram, select allEmpsDA Data Action, right mouse and chooe Run" i get a the following runtime errors:

This error is happening on a read.

<field>SUPP_ITEM.REQ_NUM</field>

<type>oracle.toplink.mappings.OneToManyMapping</type>
</database-mapping>
Object model has a Supp class that has a collection of SuppItem(s). I was allowing the Mapping Workbench to create the Java Source. I'm not to fond of that, but I thought it would be easiest to get things going.
The datamodel is similiar to the class model.

Convert String to java UTC date then to sql date

Hi,
I am trying to convert string (MM/dd/yyyy format) to UTC date time and store in the database.
This is what I did:
String dateAsString = "10/01/2007";
SimpleDateFormat formatter = new SimpleDateFormat("MM/dd/yyyy");
formatter.setTimeZone(TimeZone.getTimeZone("GMT"));
formatter.setLenient(false);
java.util.date dateValue = formatter.parse(dateAsString, new ParsePosition(0));
dateValue will be Sun Sep 30 20:00:00 EDT 2007 in UTC.
Now I need to store this date and time to MS SQL database.
I used the following code:
java.sql.Date sqlDateValue = new java.sql.Date(parsedToDate.getTime());
But this code give only the date, not time 2007-09-30
Can anybody tell me how I can change this java date to sql date (or datetime?) so that I can get both date and time.
Thanks,
semaj

How to execute vbscript through java

hi i m trying to run vbscript (that accept some command line arguments) through java .
my vbs file is stored in c: drive
purpose of vbs file : to map network drives.
i normally run it from command prompt using following syntax
c:\cscript map.vbs l: \\10.22.122.35\d$ <username> <password>
code in map.vbs
map.vbs
Dim objNetwork
Set objNetwork = WScript.CreateObject("WScript.Network")
strLocalDrive = WScript.Arguments.Item(0)
strRemoteShare = WScript.Arguments.Item(1)
strPer = "FALSE"
strUsr = WScript.Arguments.Item(2)
strPas = WScript.Arguments.Item(3)
objNetwork.MapNetworkDrive strLocalDrive, strRemoteShare, strPer, strUsr, strPas
my problem is i can easily accomplish this by using .batch file but i dont want to reveal my username and password
i just want to know is there any way thru which i can somehow link java program with dos command and execute vbs file
from my java program.
the code that i have got is not working properly or has to be modified to work.
          String os = System.getProperty("os.name").toLowerCase();
     if (os.indexOf("windows") != -1)
          String[] command = new String[]{"cmd.exe", "/c","cscript","c:\\map.vbs", '"'+strDrive+'"','"'+strPath+'"',"<username>" ,"<password>"};
          Runtime.getRuntime().exec(command);
Kindly help me as this is very urgent.

prompt for the login, the password, and the new share name, and store them in variables, then, you can do something like:
Runtime.getRuntime().exec("net use " + sharenameVar + " \\\\HOST\\share /user:HOST\\" + userVar + " \"" + passwordVar + "\"");with the following values:
HOST: PC10
user : toto
pass : a password
sharename: I:
it will result in :
net use I: \\PC10\share /user:PC10\toto "a password"
this will map the new share with the given credentials ; there is no need to add some complexity by using a vbscript to do that

Exception thrown trying to convert string to int

Hey Guys,
i imported a csv file into my app which i divide using the split() method and put into an array then I divided the array into variables;
fruit = piece[0];
price = piece[1];
unit = piece[2];Now since price has to be a double i converted it into a double;
price2 = Double.parseDouble(price);which worked grand
but when i try to convert unit to an integer
unit2 = Integer.parseInt(unit);i got error
Exception in thread "main" java.lang.NumberFormatException: For input string: "3
at java.lang.NumberFormatException.forInputString(Unknown Source)
at java.lang.Integer.parseInt(Unknown Source)
so i tried removing white spaces as follows
target = unit.replace(" ", "");which worked and displayed grand, then i tried converting to int again but the same exception was thrown, can anyone help me with this problem, thanks
mark

sorry for the messed up format previously.
Like you said the unit.replaceAll(" ", ""); did not do the trick, when displayed as a string it looked like 3 was on its own but still did not convert to int. I assume line break or something existed in the csv file like you mentioned earlier as unit was the last word in the csv file.
when i used unit.trim(); and tried to convert to integer it worked perfectly.
thanks all for your help,
Mark

Problem when trying to convert using PDFG

Hi,
I'm trying to convert come files using PDFG. I tried the user console, the email account and the WebService API. None of this options worked.
I can see in the log file that JBOSS is launched successfully, with every BMC being started without any error. The only problem that i have is taht QuartzService error but the Adobe support already told me that this was not a problem.
When trying to submit a document for conversion, the log files registered the errors below. does anyone has some clue on this problem ?

Strange problem when tried to convert HelloWorld.class..

Hi friends..
i've downloaded the Java Card SDK 2.2.1, and i tried to compile HelloWorld application that shipped with its distribution..
i found strange problem when i tried to convert HelloWorld.class into .CAP, etc.. :(
I use Windows XP, assume that i've set the Environment Variables needed
i've compiled the HelloWorld.java into HelloWorld.class..
the package of of HelloWorld is : com.sun.javacard.samples.HelloWorld;
and i use this config file :
-out EXP JCA CAP
-exportpath .
-applet 0xa0:0x0:0x0:0x0:0x62:0x3:0x1:0xc:0x1:0x1 com.sun.javacard.samples.HelloWorld.HelloWorld
com.sun.javacard.samples.HelloWorld
0xa0:0x0:0x0:0x0:0x62:0x3:0x1:0xc:0x1 1.0and then i tried to run converter script in the Console :

Trying to Convert CHAR(1) to Boolean

I have this indicator into my database which is of type CHAR(1) and I am trying to map it as object of type Boolean. But while I run it, it gives me exception:
Exception Description: The object [true], of class [class java.lang.Boolean], could not be converted to [class java.lang.Character].Local Exception Stack:

I have mapped the database values Y-->true and N-->false.
any help would be appreciated. Thanks in advance

I am using Object Type Converter. And I got that working. Thanks for the reply.
I just selected Type Character in Database field and type Boolean into Object Field.
Thanks for the reply.

Cant convert boolean to java.lang.Boolean - HUH?

I'm fairly new to Java, but I'm pretty sure this should work.
Can someone tell me why I'm getting these compiler errors:
wehServlet.java:72: Incompatible type for if. Can't convert java.lang.Boolean to boolean.
if (checkoutSpecificFile(req,res,busId,tempDir)) {
^
wehServlet.java:123: Incompatible type for return. Can't convert boolean to java.lang.Boolean.
return true;
Here's the basic code:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.*;
public class wehServlet extends HttpServlet {
private void someThing (HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
if(tryThis()) {
<do something>
} else {
<do something else>
private Boolean tryThis() {
return false;
Why can't I do this?
How do I fix it?
I tried
if(tryThis().booleanValue())....
and I get this compile error:
Incompatible type for return. Can't convert boolean to java.lang.Boolean
Now what do I do?

There's a lot of confusion caused by these "Wrapper" objects, not just Boolean but Integer, Long etc.
The basic ("primitive") types are lower case names, boolean, int, long etc..
The related items with capital letters are "wrapper" objects. The are used in a context where you basically want to store a single value but must do so as an Object, for example in aggregate objects like Map or List.
You should avoid these unless there's a specific reason to use them.
You can convert between boolean and Boolean, int and Integer etc. but it has to be done explicitly. As far as Java is concerned they're entirely different kind of thing. To java the Boolean class is just another kind of Object, it has no special syntactic significance.
boolean b;
Boolean bo;
b = bo.booleanValue(); // covert from Boolean object to boolean primitive
bo = new Boolean(b); // convert primitive to Object
if(bo.booleanValue()) { // test Boolean objed

"Property value is not valid" when PropertyGridView tries to convert a string to a custom object type.

Hi,
I have a problem with an PropertyGrid enum property that uses a type converter.
In general it works, but when I double clicking or using the scoll wheel, an error message appears:
"Property value is not valid"
Details: "Object of type 'System.String' cannot be converted to type 'myCompany.myProject.CC_myCustomProperty."
I noticed that the CommitValue method (in PropertyGridView.cs) tries to convert a string value to a CC_myCustomProperty object.
Here is the code that causes the error (see line 33):
(Using the .net symbols from the PropertyGridView.cs file)
1
        internal bool CommitValue(GridEntry ipeCur, object value) {
2
3
            Debug.WriteLineIf(CompModSwitches.DebugGridView.TraceVerbose,  "PropertyGridView:CommitValue(" + (value==null ? "null" :value.ToString()) + ")");
4
5
            int propCount = ipeCur.ChildCount;
6
            bool capture = Edit.HookMouseDown;
7
            object originalValue = null;
8
9
            try {
10
                originalValue = ipeCur.PropertyValue;
11
12
            catch {
13
                // if the getter is failing, we still want to let
14
                // the set happen.
15
16
17
            try {
18
                try {
19
                    SetFlag(FlagInPropertySet, true);
20
21
                    //if this propentry is enumerable, then once a value is selected from the editor,
22
                    //we'll want to close the drop down (like true/false).  Otherwise, if we're
23
                    //working with Anchor for ex., then we should be able to select different values
24
                    //from the editor, without having it close every time.
25
                    if (ipeCur != null &&
26
                        ipeCur.Enumerable) {
27
                           CloseDropDown();
28
29
30
                    try {
31
                        Edit.DisableMouseHook = true;
32
/*** This Step fails because the commit method is trying to convert a string to myCustom objet ***/
33
                        ipeCur.PropertyValue = value;
34
35
                    finally {
36
                        Edit.DisableMouseHook = false;
37
                        Edit.HookMouseDown = capture;
38
39
40
                catch (Exception ex) {
41
                    SetCommitError(ERROR_THROWN);
42
                    ShowInvalidMessage(ipeCur.PropertyLabel, value, ex);
43
                    return false;
44
I'm stuck.
I was wondering is there a way to work around this? Maybe extend the string converter class to accept this?
Thanks in advance,
Eric
