How to handle big java source files in JDEV 10.1.3

Hi,
I have some .java files that are like over 10,000 lines long. I know this is crazy but I didn't write it but I have to maintain it. I really dont feel like refactoring all these big source files right now.
JDeveloper has lots of while-editing features that are probably grinding to a halt on this really big file. My CPU usage shows ~97% whenever I do anything in this file.
Is there some preferences I could set or something I can disable just while editing this big file.
Thanks,
Simon.

The delays between edits and the IDE stalls seemed
about the same with this change in place.Ah... that's sad. It seems like there's another (un-configurable) timer mechanism for background parsing used by the structure pane.
I didn't
really understand what the numbers were controlling
so I didn't try any other values. They control the frequency of a timer that is reset each time you press a key in the code editor. After the number of ms specified in these parameters has elapsed after the last keypress, the code in the editor is parsed. There are two settings, one for short files and one for long files (I forget what the threshold is between short and long).
Maybe it isn't the parser since it still goes to 100%
CPU (just less often) but I can still move the mouse
around the file - no stalling. Here's something I'd find useful to investigate this problem: Run jdeveloper with jdev.exe so that you have a console. When the CPU hits 100%, switch to the console and press Ctrl+Break. Copy the stack dump (maybe take a couple of them) and email them to me (brian dot duff at oracle dot com).
Dropping the structure window is a fairly simple work
around for me. I can live without the structure
window for this file although it is actually most
useful as the file's size, and structure, increases.Yes, I can imagine the structure pane would be quite useful with a mammoth java file like the one you're working with :) Incremental find might be your friend in its absence (Ctrl+E, I think).
If your considering an ER for the structure window
(:-) then how about this too:
"Cursur location within the file should be shown in
the structure window"
This already happens for Ant (build.xml) files but
not for Java files - or at least not for me. The
problem is that it is easy to get lost in a large
file and the navigation assistance should be the same
across all structured file types. Funnily enough, I was talking to one of the developers on the team that builds the infrastructure for the xml based parts of the product (including ant) about these kind of inconsistencies between the XML and Java structure panes just a couple of days ago... :) I'll file a bug for this (rather than an ER), since it's a UI inconsistency.
Thanks,
Brian

How to handle the java.policy file ?

Can somebody tell me how to handle the java.policy file?
I always get java.net.SocketExceptions and java.security.AccessControlExceptions while connecting to an appserver from an applet.
What do I have to write in the java.policy file, where do I have to place it and do I have to call it in some way form my applet?
Thanks in advance.
don call

The java.policy file goes in your jre installation directory in .../jre/lib/security (there should be one there already).
I used it to allow otherwise restricted permissions for an applet using javax.comm. Add something like the following to the file:
grant codeBase "URL:http://yourDomainName/rootDirectoryOfYourApp/*" {
permission java.security.AllPermission;
This will give the applet downloaded from your site all permissions. You might want to give only certain permissions, I don't know.

How can I share a *.java source file across multiple projects in NetBeans?

I'm sure this simple and a pretty common operation but how can I share a *.java source file across multiple projects in NetBeans? Right now I keep cut, coping and pasting the same source file between multiple projects to re-use the same code. But I could I make this source file a library file or something like that so that I could access it from any project. I assume this would be a generic operation but I mentioned NetBeans for clarity. Thanks.

If anyone wants to be specific about NetBeans I welcome that too.

Create a class library.
Write your code, compile it to .class files, put those class files in a .jar file and include the jar file in the classpath whenever you want to compile a project against it.

How to debug byteCode? Can cap file convert to java source file?

Are there tools can debug byteCode?
Are there tools can convert cap file to java source file?
Are there tools can convert jca file to java soure file?

I think it's little bit difficult to give you a correct answer. Frankly speaking, cap file debugging is possible if you have sufficient devices and knowledge to do that. Converting cap file to java source code is also possible only if the cap file has descriptor component in it. Names of variables, functions will not be completely restored because cap file doesn't have the names in it. But I am not sure that there is a publicly opened tool to do that. JCVM chapter 6 may show you the way even it's not the direct one.

More than one class in single java source file?

Is there a way to define more than one class in single java source file?
I get a duplicate class definition error for each extra class, but I am sure there is a way to handle this in JDeveloper.
Anyone knows how ?

Please post the question in jdeveloper forum at

Getting all the members (variables, methods AND method bodies) of a java source file

For a project I want to programmatically get access to the members of java source file (member variables, methods etc) as well as to the source code of those members. My question is what is the best method for this? So far I have found the following methods:
Use AST's provided by the Java Source API and Java Tree API, as discussed in the following posts:
http://today.java.net/pub/a/today/2008/04/10/source-code-analysis-using-java-6-compiler-apis.html
http://weblogs.java.net/blog/timboudreau/archive/2008/02/see_java_code_t.html
http://netbeans.dzone.com/announcements/new-class-visualization-module
This has the disadvantage that the classes actually have to be compilable. When I look at the Netbeans Navigator view however, it provides me with a nicely formatted UI list, regardless of the "compilable" state of the class.
Thus I started looking at how to do this... The answer appears to be through the use of tools such as JavaCC: https://javacc.dev.java.net/
ANTLR: http://www.antlr.org/
which are lexers and parsers of source code. However, since the Navigator panel already does this, couldn't I use part of this code to get me the list of variables and methods in a source file? Does the Navigator API help in this regard?
Another route seems to be through tools such as
BeautyJ: http://beautyj.berlios.de/
which run on top of JavaCC if I am correct, and which has the ability to provide a clean view on your java code (or an XML view). However, BeautyJ does not seem to be too actively developed, and is only j2se1.4 compatible.
I hope someone can shed a light on the best way to go about what I want to achieve. Somebody already doing this?
(I crossposted on the Netbeans forums too, hope this is OK...)

I'm currently developing a LaTeX editor(MDI) and I do the same thing, but I don't know what exactly do you need.

Translate java source file

Dear Friends,
Does anybody know how to translate java sources file and get all the info from it.
Like i want to write a parser and want to extract its details and store in datastructures.
Any similar examples present or any suggessions please inform.
Thanks in advance.

there is a tool called javacc which generates parsing code. You can also google for "javacc grammar repository" to find a java grammer you can pick up and start using

How do i create one source file that feeds two users on the same pro book?

how do i create one source file/folder of photos that feeds two users on the same pro book?

Well you can do exactly the same with a folder of photos, just put in the Users/Shared folder.
Iphoto is a mite more complex than this. It's a database and so there's a bit more involved.
For iPhoto 09 (version 8.0.2) and later:
What you mean by 'share'.
If you want the other user to be able to see the pics, but not add to, change or alter your library, then enable Sharing in your iPhoto (Preferences -> Sharing), leave iPhoto running and use Fast User Switching to open the other account. In that account, enable 'Look For Shared Libraries'. Your Library will appear in the other source pane.
Any user can drag a pic from the Shared Library to their own in the iPhoto Window.
Remember iPhoto must be running in both accounts for this to work.
If you want the other user to have the same access to the library as you: to be able to add, edit, organise, keyword etc.
Quit iPhoto in both accounts. Move the Library to the Users / Shared Folder
(You can also use an external HD set to ignore permissions, a Disk Image or even partition your Hard Disk.)
In each account in turn: Double click on the Library to open it. (You may be asked to repair the Library Permissions.) From that point on, this will be the default library location. Both accounts will have full access to the library, in fact, both accounts will 'own' it.
However, there is a catch with this system and it is a significant one. iPhoto is not a multi-user app., it does not have the code to negotiate two users simultaneously writing to the database, and trying will cause db corruption. So only one user at a time, and back up, back up back up.

How to handle errors in a file at sender side?

Hi
I have done a file to proxy scenario.
I know how to handle errors on proxy.
But on sender side when picking the file if one the record have worng fomat its throwing mapping error and its not processing any record..
I wanted to process the records which have right format and data and all remaining recrods which have wromg format should be send back to the sender as file.
How to do this.
How to handle error in sender file.
Regards
Sowmya

Hello Sowmya,
In your scenario Three ways you can validate the data.
1) Before the data reaches into SAP system ie in XI system during Mapping or before mapping i,e in Adapter Module in the Sender side
2) this option, is in the receiver applications side. ie. Validations will be taken care in the SAP system i.e in ABAP server proxy code.
3)Through BPM, If Mapping Exception Occures then through exception Branch you can send bad formate file to sender again.
Generally, it is prefer to more business critical validations in the Application System ie Receiver Application System (ABAP Server Proxy)
In this, you can have more flexibility of the validations as you are validating some of the SAP payroll informations as Personal ID etc.
Based on the complexity and flexibility of the requirement, you can either do this in the XI (if XI, ie Sender Adapter Module or Mapping) or in the ABAP proxy

[JS][CS3]how to get refrence for source file

Hi All
I am new and learning javascript Gradually Could any one help on this as i do have a code for load style but don't know how to get refrence for "source file" and "targetDoc"
targetDoc.importStyles(charImport, sourceFile, clashPolicy);
targetDoc.importStyles(paraImport, sourceFile, clashPolicy);
Can any one figure it out
Many Thanks

I'm not sure what you are trying to achieve, could you please elaborate?
Do you want to load all the styles from one document into all 100 documents, or do you want all the styles from the 100 documents into 1 document or what is the goal?
The following will let you choose a folder of files, open each of the files in it and import the styles from source document. It is not a complete script, make sure to test and modify before running on anything else than test files :-)
var MyFolderWithFiles = Folder.selectDialog ("Choose a folder");
var sourceFile = File.openDialog("Choose the styles source");
var myFiles = MyFolderWithFiles.getFiles("*.indd");
for(i = 0; i < myFiles.length; i++) {
    theFile = myFiles[i];
    app.scriptPreferences.userInteractionLevel = UserInteractionLevels.NEVER_INTERACT;
    var targetDoc = app.open(theFile, true);
    app.scriptPreferences.userInteractionLevel = UserInteractionLevels.INTERACT_WITH_ALL;
    targetDoc.importStyles(ImportFormat.CHARACTER_STYLES_FORMAT, sourceFile, GlobalClashResolutionStrategy.LOAD_ALL_WITH_OVERWRITE);
    targetDoc.importStyles(ImportFormat.PARAGRAPH_STYLES_FORMAT, sourceFile, GlobalClashResolutionStrategy.LOAD_ALL_WITH_OVERWRITE);
    targetDoc.close(SaveOptions.YES);

Error running batch files from java source file???

Dear Friends,
hi,
this is with response to a doubt i had earlier ,
i want to run batch files from the java source file ,i tried using this code (here batrun is the batch file name that contains commands to run other java files)
try
String [] command = {"c:\\vishal\\finalmain\\batrun"};
Runtime.getRuntime().exec(command);
catch(Exception e)
but i got the following error.
java.io.IOException: CreateProcess: gnagarrun error= 2
plz. help me, i tried all combination w/o success,
in anticipation(if possible give the code after testing)
Vishal.

hello there,
i solved the prob. by using
cmd /c start filename ,but i need to pass parameters ie
cmd /c start java "c:/vishal/runfile a b" where a and b are the parameters. but it is not accepting this in Runtime.getRuntime.exec(),
any solutions ?????????

Parser converting java source file

I want to build a parser, which reads a java source and adds stubs at the start and end of a method, which might be for a public/protected/private method.
This public/protected/private keyowrd , and source file will be passed as command line arguments to the parser.
The generated output java source file should be similar to input source file with stubs.
For example , we have a java source file( A.java) file as specified below
class A{
     public m1(int m1_a, int m1_b){ }
     protected m2(int m2_x, int m2_y){ }
     private m3(int m3_p, int m3_q) { }
parser public A.java;
after parsing it should generate output source file as A.JAVA as specified below
class A{
     public m1(int m1_a, int m1_b)
{ System.out.println(" start of "A:m1"" + time: +"parameters:" +" a="+a ," b="+b)
     System.out.println(" End of "A:m1"" + time: +"parameters:" +" a="+a ," b="+b)
     protected m2(int m2_x, int m2_y){ }
     private m3(int m3_p, int m3_q) { }
Are there any tools , example programs , tips on the above problem .
Anticipating help at the earliest

HI dcminter,
I am not talking about performance tuning,
I need to build a program ( tool) which add System.out.println() statements as specified above for specific methods ( which might be public/private/protected ) which will be passed to the parser along with the java source text file.
This program(tool)should only convert from one java source text file (A.java) to another java source text (A.JAVA) file , by adding the extra System.out.println() statements.
Please help in this regard about any sample or tool or tips in solving.
Awaiting for ur reply
