Using div and dynamically creating it with for loop would be the way i will do it. If you have any better idea with displaying it i would be thankful. Reading and adding buttons is not problems. I was just looking for display.
How to put id in session via javascript or using jsp code block?
function for getting div id:
function getParent(el, parentTagName){
var obj = el;
while(obj.tagName !== parentTagName){
obj = obj.parentNode;
}
alert(obj.id);
}
html code looks like this:
<div id="0">
<form>
<input type="submit" target="pr" value="Go" onclick="getParent(this, 'DIV')">
</form>
</div>
Thanks

I would go about this differently with your javascript. Since you know the iterations you've done (using your for loop), there would be no reason to loop through the page elements testing for equality. You should change the onclick function summary to include the ID you created for your div, e.g.:
<div id="0">
<form>
<input type="submit" target="pr" value="Go" onclick="getParent(this, 0)">
</form>
</div>
(although I have to admit, I don't understand the purpose of your getParent function. It would make more sense to have the onclick of that button post a form up for processing, or kick off an AJAX request to add/remove a news item).
Hope this helps, feel free to ask some targeted follow-up questions!
Cheers!

How i make a audio and video media player .

By doing some research into the appropriate classes, like this[^].

You can see the jlGui Music Player which has been built under the Java platform. Its documentation would help you understand the packages and classes required. Also please clarify whether you are looking to build an applet or a swing application.
here is the link - http://www.javazoom.net/jlgui/jlgui.html[^]

i used ArrayList and create jni headder file.Generate JNI stub generates jobject for ArrayList in jni header file.but i dont know how do i handle this jobject.
i may use object array instead of ArrayList but i have problem for dynamic arrays.Beside i cant use List<>.please help me!!!

See here[^] for a description of handling Java types in JNI.

i saw this page but only create string array.For example i have a class that is called ObjectClass and i declare ArrayList<objectclass>.
how do i use jni side.Maybe your link explain that but i dont understand how to do or i cant see..

I am not certain, but I don't that you can access Java objects on the C/C++ side.

|

|
|
You can certainly access Java objects in C/C++.
|
|
|
|
|
Maybe you could explain how for the benefit of the OP, and me.

Still waiting for the solution as to how; I have not been able to discover it.

Your question is not clear.
Start by writing a Java method that demonstrates in an approximate fashion what you want to do in C/C++.
Each line in the java method will map into C/C++ code (one or more lines).

hmmmm...
public void Update( Coordinate3D pCoord, float pRange, float pTargetElevation,float pLeftHeading, float pRightHeading,
float pRayResolution, int pMaxNumberOfSamplePerRay, ArrayList<CoverageRay> pCoverageRay){
jUpdate(refClass, pCoord, pRange, pTargetElevation, pLeftHeading, pRightHeading, pRayResolution, pMaxNumberOfSamplePerRay, pCoverageRay);
}
private native void jUpdate(long pRefClass, Coordinate3D pCoord, float pRange, float pTargetElevation,float pLeftHeading, float pRightHeading,
float pRayResolution, int pMaxNumberOfSamplePerRay, ArrayList<CoverageRay> pCoverageRay);
JNIEXPORT void JNICALL Java_MapLayers_VectorMapLayers_CoverageMap_jUpdate
(JNIEnv *, jobject, jlong, jobject, jfloat, jfloat, jfloat, jfloat, jfloat, jint, jobject );
firstly sorry my bad english...
i have this method in java and Generate JNI Stub produced upper code.and i dont know how to use pCoverageRay and reach entities of pCoverageRay in JNI.
i hope i can explain what i want.

That isn't what I said.
Again write java code (NOT C/C++) code that represents in general what you want to do in your C/C++ code.
You then use that code as a model to create your C/C++ code.

Simple scenario: User goes to a web page, click a button, download the selected files.
Problem: the problem is the files are all separate, I would like to zip them all up and let the user just press one button to save. the zip it self is simple, yet my files are excel generated by the jsp with html code
response.setHeader("Content-Disposition", "attachment; filename=\"blah blah.xls\"");
out.println(<html>blah blah blah</html>);
So since it is generated all dynamically. Is there even a way to zip them up before they are downloaded.
Or even generate excel on the server using these html way?

Change your point of view - zip the stuff and extract single files when needed. That's much simpler.

I'm sorry if i didn't explain it well enough.
The point of the whole thing is to zip multiple dynamic generated files out, allowing the users to download the zip file in one click instead of the need to press multiple times to download multiple files.
|

To get your proposed solution to work, you're on the right track by assuming you need to do all creation/zipping on the server side. Instead of having the jsp generate the excel files, have it done in a Servlet on your server side instead, based on parameters from the JSP page.
You can then create the Excel files (likely by creating CSV files and renaming them, or using a third party library, such as JExcel (http://jexcelapi.sourceforge.net/[^]) and return the resulting .zip to the browser for download.
Cheers!

Hi,
I have an ant build script as shown below.
<target name="runscript" depends="compile">
<echo file="run.sh" append="false">java -cp ${mclib}/mundocore.jar:bin Chat</echo>
<chmod file="run.sh" perm="+x"/>
<echo file="run.bat" append="false">java -cp ${mclib}/mundocore.jar;bin Chat</echo>
</target>
The build script portion produces a batch file named run.bat, which simply executes a java compiler command.
java -cp C:\mundocore-1.0.0-RC1\lib\se/mundocore.jar;bin Chat
I want to send some commandline arguments with the run.bat script.e.g in command prompt
run.bat hello
How can i change the the ant build script to generate a batch file that can accept arbitrary number of command line arguments.
Thanks in advance...
