Java Editor bug ??

Is anyone aware that you can do the following in the code
editor
int myInt = 10;
myint.toString();
it won't compile but the code insight appears when typing
myInt. and it's treated as an object.

While developing a java program the editor is not able to ascertain the type of myint, thus, it is given the default type Object. Compilation produces an error, because a variable of type int does not have the toString() method.

Problem when using Ctr-Z in Java editor

If I create a component in the Desgin view, the switch to Java Editor and uze Cancel (or Ctrl+Z), it cancle the op�ration, ie remove the code added when the component was created. The component is also removed in Design view. However, it is stil present in the JSP code. Under deployment, it produces an error. The stacktrace says the error is about a component which is not present in the design view, wich is a bit confusing.

Looks like a bug.
To fix just remove the jsp tag for the component

Java Embedding bug in SOA Suite 11g BPEL??

I am beginning to wonder if there is a 'bug' in the SOA Suite 11g, BPEL, Java Embedding activity? Need some help as soon as possible – does the Java Embedding activity work in SOA Suite 11g?
Have tried the following on Jdev 11.1.1.1 and Jdev 11.1.1.3 – get the same error message (see below for error message).
Thanks for any help - Casey
I created a simple composite app by:
1.     Created a Composite with BPEL Process
2.     Created a BPEL variable by the name of Variable and a Simple Type of string      ({http://www.w3.org/2001/XMLSchema}string)
3.     Added an Assign activity (Assign_1) and assigned the value of “Test Var” to the variable Variable using a Copy operation.
4.     Then, after the assign activity, added a Java Embedding activity (Java_Embedding_1) with Java Version set to 1.5 and the following code:
+try{+*
String var;*
var=(String)getVariableData(Variable);*
System.out.println(var);*
+} // end try+
+catch(Exception ex){+*
System.out.println(ex.getMessage());*
+}// end catch+
Compiled and got the following error message:
Error(23,34): Failed to compile bpel generated classes.*
failure to compile the generated BPEL classes for BPEL process "BPELProcess1" of composite "default/Project1!1.0"*
The class path setting is incorrect.*
Ensure that the class path is set correctly. If this happens on the server side, verify that the custom classes or jars which this BPEL process is depending on are deployed correctly. Also verify that the run time is using the same release/version.*

Invisible caret in Sun ONE Studio 5 SE - Java Editor with black background

How to change caret color in Sun ONE Studio 5 SE - Java Editor?
The caret blinks changing its color between black and the background color.
I have changed the background color of the editor to black (the first thing I do whenever presented to a new editor...) But the caret changes its color between black and the background color, that is black - result: the caret becomes invisible.
Is it possible to change the behaviour of the caret? It could blink changing its color between the background color and a color that is visible (for dark backgrounds, white; for clear backgrounds, black).

I've found the solution myself.

Score Editor bug: syncopating a note disturbs line layout

In the example below, the instrumental part with max 2 bars per line has been created with the Layout Tool, and then the selection saved as a Score Set ( which i hope locks all the page details in place).
[img] http://i364.photobucket.com/albums/oo82/dogliege/Picture3.png [/img]
I then noticed that the red circled note is not displayed correctly - it should be a dotted eighth note and duly click on it with my Syncopate note command.
This then produces the following effect: it crunches up the bars and disturbs the line layout which was already set, cramming 3 bars onto the line above as in the example below.
[img]http://i364.photobucket.com/albums/oo82/dogliege/Picture4.png[/img]
Any solutions appreciated/workflow suggestions.. or is this just "..another L8 Score Editor bug.. wasting more of 2009"
PS Any suggestions as how to get the images to display in the post - as opposed to appear a link? cheers

i should be enjoying my holiday but i couldn't help myself...
there are a couple of fixes for this.
first, try cutting the regions somewhere to force a redraw.
second, if no form of cutting or reformatting works, try copy and pasting the midi into a fresh autoload on the intel.
particularly if the file was created pre 7.2. there can be compatibility issues between ppc and intel.

Java Editor with the HelloWorldServlet does not open

I am following the Getting Started guide lines. When choosing Finish in step 6 of "Create a HelloWorld Servlet" (https://help.hana.ondemand.com/help/frameset.htm?e5a8b1d3bb571014a0f89bb4706d4e0b.html) then the Java Editor should open.
Unfortunately this does not happen at my installation.
The only displays at the footing of the Overview picture are "Writable", "Smart Insert" und "1 : 1" for some time.
This is also interfering with a message "'Periodic workspace save.' has encountered a problem.

Did I skip something in the guide? How please should I continue editing my first HelloWorld servlet?

JDeveloper 11.1.1.2.0 Java Editor Performance

I'm having trouble using the Java editor in 11.1.1.2.0. Its been working fine for the past couple of days then just recently it starts hanging after every 10 or so characters I type. The file I'm seeing this in is about 4,000 lines. I have no other applications open, I've tried restarting the IDE and even the machine. It seems that when this happens JDeveloper CPU utilization hits 50-100%. Any suggestions? I have J2D_D3D set to false. Also, is there a log file I can look in for more details?

I have 3GB machine and I face the same issue. If the file size is too big it affects editor performance.
You can code in linux environment. That's what I used to do sometimes.
Check these blogs too.

Java Editor and Unicode Characters

I'm trying to use unicode characters in strings with the Java Editor.
String myOption = "\u2666 " + myDirName;
This works nicely, displaying a diamond in my web application. Source HTML contains a &9830;
However, if I make changes in the Visual Designer (e.g., add a button), the \u2666 in my Java code changes to a diamond symbol. When that happens, I get a "?" in my web application.
How do I prevent Java Editor from switching to the display character?

Thanks for your response.
After more research, I found that the .java file is corrupted. These means the problem is not related to the browser.
When I have "\u2666" in the Java Editor window, I see "\u2666" in the .java file in Word Pad. This is properly compiled and the entity ♦ appears in the HTML.
When the diamond symbol is in the Java Editor window, I see and ascii ? (character #3F). I get a ? in the browser. It is really a question mark (#3F) not an unknown character.
So, it appears that when the JSP is changed by adding a button, the .java code is rewritten to disk but unicode characters are not translated properly. Or - something like that. If I could keep the ascii string "\u2666" from converting to the diamond, I would be all set.
I can edit the Java Code, close, save and reopen all I want and the unicode character doesn't translate to the symbol. This ONLY happens when the JSP is modified.
Any ideas?

Java Editor - auto complete

i'm looking for a FREE lightweight java editor that supports auto-complete and possibly code generation.
auto-complete is when you type the object and a dot, the editor pop-up a window listing all methods available for you to use.
code generation (or whatever it is called) is like a template that i can use....like i type in tryc and a space and it will create a try{ } catch{} block for me
by lightwieght, i mean th eeditor is small and does not requires a lot of memory to run. don't want a full blown editor like Eclipse, JBuilder, NetBean (they're too resource hungry). something like JCreator and TextPad. My computer is old (PIII 733 mhz, 384MB RAM)..yes, my computer motherboard only allows up to 384 MB of RAM ..this sucks when RAM is soooo cheap.
i check with most free editor, but to get auto-complete and code generation...you have to pay for it...so i'm wondering if anyone knows of a FREE one?

Use the Plug-In Manager (Plugins menu item) to review the available plugins. Click the Install tab and highlight the name, it'll display a description.
There's a couple of auto completes - I use Dot Complete (it has a minor glitch starting, I have to click Complete to get it to start)
There's a number of template facilities, both built in and as plugins.

Java editor for Linux

Which is the best java editor for Linux ??
in the Win plataform I'm using the JCreator ... and now I'm migrating to the linux plataform...
please tell me the name of the editor you are using if you use Linux... (Red Hat 7.1 here...)

you can try SciTE from http://www.scintilla.org - it's simple, fast and good enough. you can work with java, c and many other programming languages. There are some features that don't present in any other editor.
Btw SciTE is only editor, not complete IDE. If you wish a full IDE with projects.. etc you can use Borland's JBuilder

Java Editor in Linux

hi all,
can someone suggest a good Java Editor for Linux? I'm currently using the BlueFish Editor and i press the DOT nothing is come out, i hope that to get an editor where the members can come out after the dot is presses. By doing this, it will minimise a lot of typing error. I had try to install the JCreator on my system, but the setup cannot run on Linux.

u mean just copy the installation to the
/usr/local??
Because i dun have the root permission and the
installation file has been downloaded at the desktopIf you don't have root permissions (and can't get them) then you probably will not be able to copy the JDK to /usr/local . You don't need the JDK to be anywhere in particular so if it is installed in your home directory then leave it there. Just make sure your 'path' is set correctly!
To check you have it configured right, use
java -version
and it should report
java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode, sharing)

A Simple Java Editor

Hello,
I am looking for a very simple(barebone)Java editor which can provide syntax highlighting facility. I need to plug it into my application.
Can anybody suggest me something?
Looking forward 2 ur replies.

Hi,
one of the most powerful editor in Java is jEdit.
But it is not only a powerful editor you can also get its editor bean with
syntax highlighting separately from http://syntax.jedit.org/.
So you can have both: An editor to use and a component to integrate into your apps.
Bye

Disable Immediate syntax checker in Java editor

Could anyone suggest how to disable the syntax checker in Creator's java editor? Would be helpful if I could run it on demand, just immediately before bulding the project. Or even not run at all, as syntax errors are shown during the build.
The idea is to increase the performance and prevent occasional but still unwanted popups from the bottom of the screen.
Thanks,
-Ivan

Does anybody know how to do that? After I've made the change Creator stalls for a sec trying to parse the code and detect the errors. But quite often I want to leave the code as it is and get back to it later. Creator starts to complain about syntax errors, etc. Quite an annoying thing, could anyone suggest anything?

Using Emacs as Java editor

Hello
I suppose that most of you use Eclipse development platform. But I recently installed Emacs as Java editor.
I don't find one thing : How to activate the code completion ?
For example : I begin to type JF and by pressing TAB, it fills JFrame
thanks
bye

Ctrl-Meta-/
(Alt instead of Meta on keyboards without Meta).
Ctrl-H a compl will list all commands to do with completion
Last time I saw any stats, emacs was still ahead of Eclipse in popularity, but it wasn't important enough to me to remember what the article was.
(normally I use ArmedBear J <http://armedbear.org>, then emacs if it's not available, and JBuilder about once a month for step-wise debugging)
