How to load JVM without specifying jvm.dll

How can I load JVM from native C++ code withoutknowing the path of jvm.dll?

If on Windows, use the registry to find the place where the JRE has been installed. Take a look at the file java_md.c in the launcher subdirectory of the src.zip file supplied along with the JDK. Specifically, you will probably be most interested in the GetStringFromRegistry and GetPublicJREHome functions there.
In the registry, look for the key HKEY_LOCAL_MACHINE\Software\JavaSoft\Java Runtime Environment. That has a number of values you will probably want.
If not on Windows, I really don't know how to find the location of the JRE installation without it being configured in an environment variable, or being hardcoded.
Hope it helps.
Cheers.

TEXT_IO.FOPEN how to pick file without specifying the full directory path

Hi,
I am using Oracle application server 10gR2 on Linux with forms 10g application. I am building the DEV/TEST/UAT environment on same Linux machine with one OAS.
I am using TEXT_IO.FOPEN ('/home/oracle/check.txt','r') to read a server side file and it is working fine.
Now I want to pick this file dynamically i.e. without specifying the full path. I am using TEXT_IO.FOPEN ('check.txt','r') and I copied file in forms_path directory in linux and even in $path directory in linux but none of them are working.
Pls help me sort out this problem.
Thanks in advance

How to load jsp without menubar using shortcut?

I know, everything is possible,... so:
I have a webapp with jsp's which I start using javascript's 'window.open' command on our website. All pages are without menubar, toolbar, fixed size, etc...
However, I noticed that the users can make a 'shortcut' using 'drag 'n drop' to their desktop. When the user loads the application using this shortcut, the windows have toolbars, menubars available... which I don't like...
How can I avoid this?

you might be able to use javascript to detect if the browser window that the page is currently loaded has those bars loaded. If it does, then re-invoke your "open page in new window" logic to remove them and the original window.
Granted, I cannot be sure that you can verify that with javascript, but you could probably check out the comp.lang.javascript user group over on google for more info in that domain.

Bulk Load data without specifying column names in control file

I am totally new to the world of Oracle databases and am having some trouble doing some basic data imports from a csv file. I have a large amount of data in an excel spreadsheet (a couple hundred columns by varying numbers of rows from 2- several thousand) which I want to import into my Oracle 11g Database. Currently I am trying to use sql loader and specify the import syntax in the control file. From the examples I've seen so far, it seems you must specify the columns individually for what you are importing. This is simply not reasonable for several hundred columns of data.
Is there sql loader syntax (or a better method all together) to import a comma delimited csv or excel spreadsheet into an oracle database where it automatically generates a table and columns based on the data in the target import file? Even if I must first create the table in the database, my key issue is being able to generate the column names during import to match the column headers in the import file. I appreciate any help you could provide.
FYI here is my first meager attempt at importing a comma delimited csv, here is my ctl file:
load data
infile 'C:\filepath\mock_data.csv'
into table allData
fields terminated by "," optionally enclosed by '"'
It says Syntax error at line 4. Expecting "(", found end of file.
I suspect there is more at issue here than a missing "("

You have to create the control file to map to the table.
Since you would already have created the tables, you could generate the controlfiles based on the table structures.
See the "unloader.zip" file under the Files link at http://asktom.oracle.com
-- it has scripts to create unload a table to a flat file and to create the SQLLoader controlfile to reload that data to another target database. It would be the second set of scripts that you can use.

How to load text without a variable

As far as i know in AS2 to load a text i need to define a
variable in text like:
text=this is the text displayed.
right now i have to display a text verision of a website
which i cant put a variable like "text=" into it, im wondering is
there anyway to load text in AS2 without using a variable? because
in AS3 you can use the URLLoader.
Andrei1 pointed out that getURL might work, does anyone know?
thanks a lot

How to load jvm.dll (in C++) ?

Hi friends,
I've started using JVM for one of my software. I've understood how it works.
But now i want to create my own application which can take any .class or .jar file and then start executing the same through my program (C++).
I don't know from where to start. Can anybody help me? (May be with some sample code of C++ for the same?)
Thanks in advance

Thanks for responding my query,
But i'm aware of how to load any dll in C++, but i want to know which functions are avaible with jvm.dll and help on those functions.
For example JNIenv or some thing is used in C++ which is related to java environment. So what do that mean?
If i want to know how many classes exist in given jar file then which method out of jvm.dll should i go for?
If some I get some program, that will be beneficial.
Thanks again.

How to load and use JVM form other types of applications ?

Hello
I have a site that runs with ASP and I would like to execute some java applications to output some of the pages.
I there a way to execute java programs in the JVM without having to create a new process running java.exe ?
Like using and ActiveX component or a special .dll from Sun. How does a web browser run applets ?
I can not use .jsp directly for my pages because my client also uses some custom language (MediaBase)
they bought that works only with ASP.
Thank you,
Timothy Madden,

Yes, or something like IPC with a service process, as Michael said.
First I wanted to know if JNI has an option the create a shared VM, since my client's web server has some other processes running that also run the JVM. Now it looks like JNI will load the JVM in-process, although the documentation says little about this, but the InitArgs structure has no 'is_shared' member.
But all these are complicated for some web page, difficult to invoke from a scripting language, and there is too much effort just to use some library that happens to be written in Java, which I use to export search results into an Excel workbook (the library is Apache POI). I mean I would do it, but my client will not understand the need for this effort. Than I also want some data transferred between my web script and the java application.
So I am going to stick to java.exe and create a new process on every hit, with the standard input, output and error files redirected to some vars in my script. At least until I find out more.
Thank you,

How to unload a class or a dll from jvm?

We can load a class or a dll into jvm,but how can we unload a class or a dll from jvm?
I'm look forward to your reply.
Regard!
Sun.Huang

i don't believe you can unload a class.A class can only be unloaded if its classloader
becomes unreachable, so classes loaded by the
bootstrap loader will never be unloaded.Are they definately unloaded in that case? as soonas
the classloader that loaded them is unreachable?or
is it still an optional decision for the jvm?A class may be unloaded if and only if its defining
classloader may be reclaimed by the garbage
collector. There are no guarantees that a class will
be unloaded.Okay, that's what I thought. Thanks for confirming.

You have oracle 10g and python 2.6. Are you sure you installed the cx_Oracle version that is compatible with those particular Python and Oracle's versions? (It comes in several flavours so you need to be sure you installed the right one).

How to Format DataTable Column after load Datatable without extra loop ??

How to Format Column after load Datatable without extra loop ??
I dont want to do extra logic which can cause performance thing.
I have datatable which get fill from Dataset after database query, now i need to format column as decimal but without extra logic.
I was thinking to create clone and than Import row loop but it ll kill performance, its WPF application.
Thanks
Jumpingboy

You cannot do any custom things at all without doing some "extra logic". Formatting a number as decimal is certainly not a performance killer in any way whatsoever though.
If you are displaying the contents of the DataTable in a DataGrid you could specify a StringFormat in the XAML:
<DataGrid x:Name="dg1" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Header="Number" Binding="{Binding num, StringFormat=N2}"/>
</DataGrid.Columns>
</DataGrid>
Or if you are using auto-generated columns you could handle the AutoGeneratingColumn event:
public MainWindow() {
InitializeComponent();
DataTable table1 = new DataTable();
table1.Columns.Add(new DataColumn("num")
DataType = typeof(decimal)
table1.Rows.Add(1.444444444444);
table1.Rows.Add(7.444444444444);
dg1.ItemsSource = table1.DefaultView;
dg1.AutoGeneratingColumn += dg1_AutoGeneratingColumn;
void dg1_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e) {
if (e.PropertyName == "num") {
DataGridTextColumn column = e.Column as DataGridTextColumn;
column.Binding.StringFormat = "N2";
<DataGrid x:Name="dg1" />

How to load an image without a gui? big problems...

Hey guys, I usually try my best to not ask for help and figure stuff out myself. But this last week i've been having big problems with this work project.
My goal is to load images from disk, and append them to each other to create one big image.
The images are 0-9.jpg each file containing a number in it. then i create one big file with 4 numbers in it. called final.jpg.
so far i can do all this, but whenever the program is finished, the application just keeps running. the program has literally gone through all the steps... i have a system.out.println printed on the last line after the main, after the class instantiation... and still it stays running.
how do you guys load images without a gui? This program will probably be running under unix, so i can't create a (for component example)
Panel() and media track the file load... so i'm pretty much stumped
any help you guys can provide would be really incredibly helpfull at this point. I have searched these threads for a few hours without luck. I found only 1 real post related to my problem, but eventually they said use MediaTracker = new Mediatracker( new Panel() ); which i can't use. :(
Thanks a lot guys.
:D

yeah tried doing that, didn't work either.
UPDATE
I FINALLY found a way...
and here it is for others to find!
public BufferedImage getImage(String filename) throws Exception {
FileInputStream input = new FileInputStream( filename );
JPEGImageDecoder decoder = JPEGCodec.createJPEGDecoder( input );
BufferedImage image = decoder.decodeAsBufferedImage();
return image;
it returns an image buffer, but it's better than nothing! :)
atleast this functions under unix.
