How to make gif-animations from java-midlets?

I have produced a collection of Java animations as midlets.
I am planning to make gif-animations of some of them.
I suppose I can make a gif-picture of every frame of the applet
through coding that myself in the code. Then I could take
those gif-pictures and make an animation of them
with some animation software. Is this a good approach?
If so, what is the best software for doing this?

What I need to do is to make color wallpapers. Do you know any better approach for doing this?

How to make exe files from java files

Ohhh, so you thought you were going to answer that question? Well I already know the answer, i.e. all the tricks with the jar files or the programs which convert java programs into executable programs.
The reason why I asked this question was to start a discussion concerning question which are frequently asked in the forums. Wouldn�t it be nice to have like statistics over the most faq here, and of course one or several pages with the answers to these questions? This would solve 2 problems:
1) The person who wants to ask the question can find the answer and the solution quickly.
2) The forums would not be packed with the same questions all the time.
I mean, you must admit that the questions regarding �exe files� are asked a lot of times.
Happy coding to ya all!

Yeah thats my point! these questions should be moved
to a special page, where the answer to theam areDid you the whole message? I said there are FAQs.

How to make "Levels" in simple java game

I just wanted to know if anybody knew how to make "Levels" in a java game. In my case, it is to change two polygons that are used in the background. I think you have to use an array of some kind, but i dont really know.
Here is my source, the polygons are by the massive ///////// areas.
I cut out the majority of the program, because it was too long.
public class collision extends Applet implements MouseListener,MouseMotionListener
    private Image rickImage,mazeImage;
   Image Buffer;
   Graphics gBuffer;
   int x, y;
   int[] LeftWallX = {0,204,204,149,149,162,162,243,260,235,259,232,260,230,207,207,0};
   int[] LeftWallY = {500,499,402,402,341,324,227,191,157,141,135,123,116,109,86,1,1};

             playerArea= new Polygon(PlayAreaX,PlayAreaY,31);
             leftWall= new Polygon(LeftWallX,LeftWallY,17);

             drawStuff();
             g.drawImage (Buffer,0,0, this);
*/

I'm not exactly sure in your case what you are trying to accomplish. If all you want to do is make new polygons for your levels then you will simply need a Vector of type level (or polygon). Store multiple levels/polygons in that vector. This can be done many ways, probably the most efficient way would be to create a class Level of sorts and create each level object from there. This way you have all your levels stored into that vector.
I have made programs where the levels/mazes are randomly generated based on certain parameters (this way you would not need to define any specific level). This can be done inside the Level class and added to the vector so that when a level is randomly generated there are literally infinite possibilities. I would suggest posting all your code or at least a breakdown UML diagram of what is going on in your entire program.

Thank you for your answer.
I do use cdn off for publish setting.
The Web site that I am working on is a very complicated site. Edge
animations are in a subdirectory of Apache server.
When server is offline, I get all files from Appcache without problem,
excepted *_EdgePreload.js.
I Google hundreds time, cannot find answer on why this file is always get
online.
Finally, I find out myself, Adobe Edge don’t like relative file path for
*_EdgePreload.js.
Change to root absolute path fixed the problem:

Help! How to convert an instance from java.lang.Object to a particula class

* How to convert an instance from java.lang.Object class to a particular class
witch is known only at the running time?
Roster EJB component is make up of RosterHome, Roster and RosterBean.
RosterHome is the home interface of Roster EJB.
Roster is the remote interface of Roster EJB.
RosterBean is the implement of Roster EJB.
The following code segment is to invoke Roster EJB component.
String jndiName="roster.RosterHome";
javax.naming.Context initial = getInitialContext();//getInitialContext() returns a instance of Context.
Object objref = initial.lookup(jndiName);
RosterHome home =
(RosterHome)javax.rmi.PortableRemoteObject.narrow(objref,
RosterHome.class);
Roster myRoster = home.create();
String team="T1"
String player="Tom"
myRoster.addPlayer(player,team);
But, now, all the home interface, the remote interface and the JNDI Name of
Roster EJB component are not been known at the compiling time. However They are
known at the running time, throught reading from the XML config file.
Questions:
1,How to write code for this case ? or
2,How to convert an instance from Object class to a particular class witch is known
only at the running time?
String jndiName="roster.RosterHome";// in fact, reads from XML file.
String homeClassName="roster.RosterHome";// in fact, reads from XML file.
String remoteClassName="roster.Roster";// in fact, reads from XML file.
javax.naming.Context initial = getInitialContext();//getInitialContext() returns a instance of Context.
Object objref = initial.lookup(jndiName);
Object objHome= javax.rmi.PortableRemoteObject.narrow(objref,
Class.forName(homeClassName));
/* how to do next?
}

I am not sure what you are trying to do. But at some point you should know which methods to call on the remote interfaces. Maybe the method names are stored in the XML file as well or you have a set of standard method names (also consider parameters).
However, this can be solved by reflection. Look at the java.lang.reflect package, especially java.lang.reflect.Method, and also at java.lang.Class.
If you are doing this on the app server:
I've seen posts where people say that reflection is not permitted in EJB, but I don't think so. Check the EJB spec.
If you are doing this in an application: reflection is always permitted. Probably also in applets and JSP.

How to Create adf table from java bean

Hi,
How to Create adf table from java class (Not from ADF BC).
Thanks
Satya

@vlsn -- you have to follow what shay said.
Do the following in Model layer ::
create a table property java class with your columns setters and getters like :
*public class gridProps {*
private int sno;
private String orderNum;
*public void setSno(int sno) {*
this.sno = sno;
*public int getSno() {*
return sno;
*public void setOrderNum(String orderNum) {*
this.orderNum = orderNum;
*public String getOrderNum() {*
return orderNum;
Create another table java class which will populate the values to your column values and return the collection :
*public class gridPopulate {*
private List<gridProps> gridValues ;
*public List<gridProps> setToGrid(ArrayList<ArrayList> valuesToSet) {*
*if (valuesToSet == null) {*
return gridValues;
gridValues = new ArrayList<gridProps>();
if(btnValue.equals("completeBtn"))
return gridValues;
for(ArrayList<String> tempArr:valuesToSet)
gridProps gp = new gridProps();
gp.setSno(Integer.valueOf(tempArr.get(0)));
gp.setOrderNum(tempArr.get(1));
return gridValues;
Right click gridPopulate class and create this as data control.This class will be seen in Data control list.Under this data control,Drag the grid property collection(created earlier) to your page.Then execute your binding(gridPopulate) according to your logic.
Thanks.(My jdev version 11.1.1.5.0)

How to execute Linux command from Java app.

Hi all,
Could anyone show me how to execute Linux command from Java app. For example, I have the need to execute the "ls" command from my Java app (which is running on the Linux machine), how should I write the codes?
Thanks a lot,

You can use "built-in" shell commands, you just need to invoke the shell and tell it to run the command. See the -c switch in the man page for your shell. But, "ls" isn't built-in anyays.
If you use exec, you will want to set the directory with the dir argument to exec, or add it to the command or cmdarray. See the API for the variants of java.lang.Runtime.exec(). (If you're invoking it repeatedly, you can most likely modify a cmdarray more efficiently than having exec() decompose your command).
You will also definitely want to save the returned Process and read the output from it (possibly stderr too and get an exit status). See API for java.lang.Process. Here's an example
java.io.BufferedReader br =
new java.io.BufferedReader(new java.io.InputStreamReader(
Runtime.getRuntime().exec ("/sbin/ifconfig ppp0").
getInputStream()));
while ((s = br.readLine()) != null) {...

How to call gnuplot command from java

Hi there,
In our course, we are required to develop an GUI for gnuplot. In case you don't know about gnuplot, it's a plotting program and has lots of command. We want to use java and swing, but now we don't know how to call gnuplot command from java, or how to execute a shell command(script) from java.
By the way, since we need read in files with several columns of data and allow user to select a column, we want to use JTable. Is that reasonable?
Thanks a lot for any suggestions!
Jack

Hi, there:
Will using JTable add much overhead? I may have to use several JTables and switch among them. I can add scroll bar to or edit JTables, right?
BTW, do you have experience about gnuplot? Can I find the command tree of gnuplot somewhere? Or do you know a better place to post question about gnuplot? unix/linux group, maybe.
Thanks,
Jack
P.S. Would you guys answer my question after I use up my duke dollars? :- )

How do I make a silhouette from a portrait?
Ah, but wouldn’t it be ever so much easier to explain if you actually provided (a lores of) the image in question?
And how do I make the background transparent?
Preferably with a Layer Mask and then saving in the appropriate file format (psd or png24 for example support transparency).

I need to know how to set environment variables from java
I want to set from java for example the environment variable "TestVar" with the value "TestValue"!1) That functionality does not belong in an application. You're trying to set environment variables, which are global across all applications, at either the user level as a whole, or across the entire machine (system level). Or, if you're only trying to set a variable active for the current process, you don't need to do that.
2) Environment variables are not a platform-independent entity, and are thus against the nature of Java.
My gut feel is that you are designing something in a backwards way, so my point is mainly to point that out, not to try to help you solve that particular problem.
