Using Eclipse instead of XCode/Visual C++ ?
Hello everybody,
I am pretty sure this question has already been asked, but I can't get any answer.
Why does Adobe recommend (and distribute samples) based on XCode and Visual C++? Why is there no documentation/projects based on Eclipse ? I can't see any problems using Eclipse, excepted Xcode/Visual C++ based sample projects and docs.
I have been working for monthes on Eclipse and I can only see advantages using it :
Cross-platform : no need to have Windows and OSX projects.
More functionalities : What about functionality such as call hierarchy, classes navigator, automatic suggestions... ?
Better integration : CPPUnit, Maven... What a wonderful world out of reach !
Has anyone among you ever tried to use Eclipse for InDesign plugin development ? What were the problems ? Why Adobe does not event mention the possibility to develop with Eclipse ? Is it really difficult to migrate to Eclipse projects ?
I'd like to read your feedbacks
Thanks in advance.
Regards
Hello,
Yes, you can use still use the plugin.
Refer "http://www.oracle.com/technology/products/enterprise-pack-for-eclipse/index.html".
thanks

Hi,
For developing portals in Webcenter can i use Eclipse instead of JDeveloper?
Is there any plugins needed for Eclipse to use Webcenter?
Regards,
Venu--Hi,
WebCenter is dependent on ADF and there is no Eclipse plugin for this. However, best to ask on the WebCenter forum

Exception access violation using jlong instead of jint
Hi,
I hope you can help me.
I'm using Java5 under Windows XP and I'm developing under Eclipse.
I try to use an "old" c-Application accesed via JNI.
Status Quo is that, I have access to the c-side, over my JNI-conform DLL. My current task is to translate the c-side structs to java-objects. This also works, but only with limitation.
Calling methods bidirectional is working, manipulation a java-object is like a walk on an warm and sunny Saturday afternoon.
But I'm not able to use all possible parameters (for now I have tried to use jobject, jstring, jint, jboolean, jlong).
The first problem I had, were using Strings as parameters, but this now I deal with the loopway over java/lang/object (using java/lang/String results in an access_violation).
The next problem, and the harder one, is, that I cannot use the type long or jlong.
int (jint) is no problem, with int all works fine, but if I change the environment, creating and using long, I allways get an the access_violation shown below.
Is there anything, I need to know?
working c-side-code:
jobject someObject;
jint anIntegerValue;
anIntegerValue =5;
jmethodID mid3 = (*env)->GetMethodID(env, cl, "initReturnSomeObject", "(ILjava/lang/Object;)Ljava/lang/Object;");
if(mid3 == (jmethodID)0) printf("\ndooofes MethodName4!\n");
else {
const char* myParams;
myParams = "ooooohwow!!!";
someObject = (*env)->CallObjectMethod(env, jobj, mid3,
anIntegerValue, (*env)->NewStringUTF(env, myParams));
}wokring java-side-code
public Object initReturnSomeObject(int i, Object obj) {
String s = (String)obj;
System.out.println("String: "+s+"\nInteger: "+i);
some = new SomeObject(s,i);
if(some==null) System.out.println("Some is not yet initialized, FEAR!!!!\n");
else System.out.println("Yoh, I'm soooo many good!! \nSome:\nString: "+some.getS1()+"\nInt: "+some.getI1()+"\n");
return (Object)some;
so, und this code, doesn't work. you can see, the changes are dramatically!! ;)
sorry for my sarcasm. I do not know, why it doesn't work.
jlong aLongValue;
aLongValue = 2;
jmethodID mid3 = (*env)->GetMethodID(env, cl, "initReturnSomeObject", "(JLjava/lang/Object;)Ljava/lang/Object;");
if(mid3 == (jmethodID)0) printf("\ndooofes MethodName4!\n");
else {
const char* myParams;
myParams = "ooooohwow!!!";
someObject = (*env)->CallObjectMethod(env, jobj, mid3,
aLongValue, (*env)->NewStringUTF(env, myParams));
public Object initReturnSomeObject(long i, Object obj) {
String s = (String)obj;
System.out.println("String: "+s+"\nInteger: "+i+"\nLong: ");
some = new SomeObject(s,(int)i);
if(some==null) System.out.println("Some is not yet initialized, FEAR!!!!\n");
else System.out.println("Yoh, I'm soooo many good!! \nSome:\nString: "+some.getS1()+"\nInt: "+some.getI1()+"\n");
return (Object)some;

till later.Hi,
I'm quite sure, the signature is correct. For failure check, yesterday I ran javap to check the signature, but I do also mean, that I changed the signature afterwards for several time. And, it works ;) at least the way, using Integer.
Trying to use java/lang/String everytime I got the Error, that the method could not be found - this is the part, I was wrong in my description. So the error-Message is a different one.
Belonging to the question for assumptions I made... it's difficult. I'm quite new to JNI, so, I don't know, what I can assume to do. The Method call seems to be a kind of reflection-mechanism. So I assume that the behaviour is similar. But reflection I'm not very firm, either ^^.
What I do assume is, that the parameter-value J fits to the java-type jlong. But a work around on this, I will try today. getting the jlong into an char* or using long instead of jlong or using Ljava/lang/Long; or a casted Long as Ljava/lang/Object; ...
I'm anxious to the ideas, I will have, bypassing this point. if there is no way, I will write a file, send a email or something like this ;)
Thx for thinking about my problem jschel!! It's great not to be alone.

Errors when deploying application to a remote WebLogic server using Eclipse
I'm using Eclipse with OEPE for WebLogic 10.3.5 on linux and running a weblogic server versioned the same.
I've created a new EAR which combined several EARs that I had, and deployed it on my local server using the 'servers' tab in Eclipse. It went well.
When I tried to deploy the EAR into my remote server, I got the exception:
Application archive not found : myworkspace/.metadata/.plugins/org.eclipse.core.resources/.projects/MyEAR/beadep/remote_weblogic/MyEAR/split_src.ear
This also happens when trying to deploy the EAR to a server that runs on my computer but configured as 'remote' in Eclipse. This does not happen for any other application of mine.
Next thing I tried is to update my Eclipse OEPE and server to 12.1.1, so I've downloaded the two, installed them both as new, and now when I'm looking for remote servers in the Eclipse, instead of writing the server status (republish/synchronized) it writes:
User: myuser, failed to be authenticated
I'm lost. How can I deploy my application with Eclipse OEPE to a remote weblogic server?

How to do "java Program 50 7" when using Eclipse?
If you use the command-line environment to compile and run a java program called Sample.java instead of using Eclipse, you could compile by writing "java Sample 30 5" or replace the 30 and 5 with other numbers (lets suppose the Sample.java needs 2 int inputs). How would you do the equivalent of that when using Eclipse?
Thanks!In the Run , there is an arguments tab ..

DTP plugin can't connect to 10g DB that uses SERVICE_NAME instead of SID
Hi,
I am trying to set up a connection to a database that uses a service name instead of a SID (see below for the TNSNAMES entry. It gets an ORA-12505 error because the listener does not know of SID given in connect descriptor. The Connection descriptor used by the client was:
tdc-sun-77-vip.unix.tdc.xxxyyy.com:1521:SRV_TMS_TNV.
My understanding is that the url for JDBC for service name should use a "/" instead of a ":" to separate the port from the service name. The dialog for creating the connection in SQL Developer has radio buttons to choose between SID and Service Name, so it can generate the url appropriately. The wizard for the Eclipse plugin does not have this option and the plugin always uses a ":" as the separator.
If anyone else has encountered this and gotten around it I would appreciate knowing how.
I am using the Oracle Database Tools 1.2.0.200907171332 for Eclipse Galileo.
Thanks... Bob

(5) Click on the icon to the right of Drivers: Oracle Thin Driver. This allows one to edit the driver definition.
(6) Change ConnectionURL to 'jdbc:oracle:thin:@server:1521/servicename. This will prove that the plug-in is not using the driver definition as a template.
(7) Use SQL Developer to probe your database. Ensure that the database is one that requires a service name and cannot connect using a SID.
(8) In the "New Connection Profile" dialog....
SID: (try a service name for a database that requires it)
Fill in Host, Port number, User name, and Password.
Note that the ConnectionURL contains a colon instead of a slash in front of the service name. The plug-in seems to be using the colon.

Dbxml 2.3.10 build using Eclipse
Can the dbxml 2.3.10 be built using the Eclipse IDE on Windows XP? I do not have Visual Studio as the README suggests using.
Right now I do not have a jar directory under my dbxml install directory and do not have the required libraries: db.jar, dbxml.jar and dbxmlexamples.jar
Is there a binary download of dbxml so I do not have to build?The Java libraries for dbxml require you to build C++ libraries, so Eclipse for Java developers cannot be used to build it.
However, you can use the free version of Visual Studios, Visual Studios Express Edition, to build dbxml. The jar directory and files will be created during the build, and once built you can use Eclipse to develop in Java.
Eclipse does have issues with the directory structure of the Java example programs, but it works very well with the Java API source. Plus, if you are feeling adventurous you can set up Eclipse and Visual Studio to work together so you can debug both the Java and the C++ at once.

Developing JSP pages using Eclipse 3.6
i want to build a web application using JSP pages and oracle 11i databse, so i install and configure eclipse 3.2.2 and i installed the plugin to support creating a dynamic web project and i have installed jboss 6 to be the server.
so on the eclipse i clikc new "dynamic web project" , then inside this new project i create a new JSP pages , then i write a simple code inside the jsp and i run the project using jboss and every thing went smootly.
but let say now that i want to develop a more complicated pages to add buttons , to have tabs on my page.
1. so my question is does eclipse provide a visual develpment tools ot plug-in for developing JSP?
2. where i can find some good tutorilas regarding developing JSP using eclipse 3.2.2
Thanks
Edited by: 812643 on 20-Nov-2010 17:42Confusing isn't it? You can post questions here for specific problems you need to solve and usually get an answer (eventually). However, asking for which technologies are better will probably only provide you with biased opinions. There are many alternatives, each providing its own trade offs. I suggest searching google for articles from respected sources such as 'theserverside' rather than depend on individuals. Also, limit your search to articles that are no older than about 1 year. Lastly, try to stick with technologies that are used by the bulk of the developers and are considered almost an industry standard. No point learning some good yet obscure technology.
As far as not considering a career as a developer, I suggest you stick to it no matter what. Anything you want to be good at takes years of practice and study
(http://365pwords.wordpress.com/2009/01/25/practice-practice-practice-the-theory-of-10000-hours).
No one has a 'knack' or is born good at it (even if they claim to be), and everyone experiences frustration (20 years later, I'm still frustrated!). You advance by making countless mistakes, and refactoring over and over again. Ignore anyone who discourages you no matter what.
I think your quest should be limited to what you should learn when just starting out and not what is the best technologies for experienced users. Personally, I think learning JSP/Servlets is foundation that you should know well before considering alternatives. Also, many alternatives are based on extending JSPs and therefore you should know them well. I've always used JSP and not alternatives, so I can't comment further on that topic.
If your just starting out in web design, here are my recommendations (in roughly this order):
java -book (search amazon.com for books and reviews of what others have said in them).
practice compiling java classes from the book on the dos command line and using a text editor before moving on to
an IDE.
Eclipse IDE - just an on-line tutorial may be ok. Learn to compile code, run it, debug it.
JSP - book
Servlets - book
JUnit - just an on-line tutorial may be ok
JSTL - just an on-line tutorial may be ok (use JSTL with JSP, not scriptlets)
XHTML - just an on-line tutorial may be ok
Javascript - book
CSS - on line tutorial may be ok
Tomcat - just an on-line tutorial may be ok. You can move onto JBoss, etc later.
JDBC - book
A free database such as Oracle Lite or MySql installed. Learn how to create tables.
MVC design - read up on separation of concerns on a design (presentation,control,business, and database layer).
SQL - book
JQuery - book
Hibernate -book
Spring framework - book (only after creating an MVC web application with a single servlet as the control layer)

Problem Exporting .Jar Using Eclipse
I have a small problem of exporting using Eclipse 3.2
First , i could , debug , run as application with no problem.
however after i compiled into jar , and i tried opening the jar file
theres no responses. what could possibly be the problem ?
my manifest file includes the main class of program and all external .jar files.
below is my main class
-automatic batch printing
-able to select target folder for batch printing
-able to select interval for printing
-able to stop printing
-includes log of activity of threads and printing services
-free for all to use =D

How do I use Qt and OpenGL with Visual Studio
Hi! I mainly want to program in C++ and I want to use Qt and OpenGL with Visual Studio.
I am currently revising C++ and later on i am going to start reading Qt and OpenGL. I have a background of

Im familiar with running an application i create thru command prompt or eclipse, how do i create a file to run on any computer with java so i can double click the file and my application runs. C# automatically does this, do i need to do an extra step to the jar file?
Hi,
You need to make an executable JAR file. There are a few ways you can do this but since you are using Eclipse you can follow this tutorial.
[http://www.fsl.cs.sunysb.edu/~dquigley/cse219/index.php?it=eclipse&tt=jar&pf=y]
The most important part is the manifest file, if you have dependencies on other JAR files they will need to be specified along with the
main method to call to start you program. You can do this via the Eclipse Wizard.
It will be in your interests to read this tutorial also

I just found my old ipod touch (i think 1st generation) and would like to let my toddler use it instead of my phone. I am trying to download apps but it say I need to update to 4.3 but it won't let me update. I have the most recent itunes. any idea why? I saw a thread saying to purchase the newest software (that was posted a few years ago) I paid 4.95 for the software and it's still saying it can't be updated. Am I just SOL??
The 1G iPod can only go as high as 3.1.3. The 1G does not have an internal speaker or volume buttons on the upper left edge.
Identifying iPod models
To more easily find compatible apps:
iOSSearch - search the iTunes store for compatible apps.
Apple Club - filter apps by iOS version. -
How to modify a lookup field-type to use checkbox instead of radiobutton?
How to modify a lookup field-type to use checkbox instead of radiobutton?
I would like to modify the behavior for the lookup field.
Normally you get a screen where it is possible to search through a lookup. The items resulted from the search are listed as radiobutton items. Therefore you can select only one at the time to be added.
Is it possible to have the items to be listed as checkbox instead? So that you can check multiple items and therefore be able to add multiple items at the time?
For example:
To add the user to 10 different groups on MS-AD.
It is desired to have the ability to check multiple groups to be added instead only one at the time.
My client would like to use this feature in many other situations.Displaying will not be a big deal but with that you have to customize the action class and its working as well.

Using eclipse to generate a class skeleton
Hi,
I'm using Eclipse to write some Java classes. I've already got the API for these classes, I just need to implement them.
Is there some quick way to make Eclipse generate a skeleton of the classes? i.e. I just want to give the signatures of the methods as input, and get a skeleton in return.
Thanks in advance.
Edited by: n_creep on Dec 31, 2007 4:50 PMYes, Go into the Window - Preferences menu and then work your way to the
Java - Editor - Templates section. You can create some templates that can easily and quickly produce class skeletons. For instance, this is my Template named SwingMain for displaying with a JFrame a class that subclasses JPanel:
private static void createAndShowUI()
JFrame${cursor} frame = new JFrame("${primary_type_name}");
frame.getContentPane().add(new ${primary_type_name}());
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
public static void main(String[] args)
java.awt.EventQueue.invokeLater(new Runnable()
public void run()
createAndShowUI();
}
