HotSpot source code explanation

Hi!!
I am new in this, so I will try to be as clear as I am able :)
I need to modify the source code of the hotspot, and I do not find any information about the meaning of each file in the directory tree. I have tried to do it by myself, but it is a bit complicated for me ;P
Any suggestion, WP, idea or anything about the meaning or the content of each file (as many as you can) will be of a huge help :D:D:D
Thx!! :D:D:D:D

Hi!!!
I am doing a project about improving certains features in the JVM ;) so I need to modify the source code of the hotspot :)
Thx!! :D

Hotspot source code

Hi,
We want to make a comparison between the source code of the Hotspot JVM v1.4.2 and the source code of Hotspot v1.6 (to analyze the system calls which are made by Hotspot under Linux when using the threading API).
However, the former seems not to be available since the JVM became Open Source after the release of the 1.4.2 version...
Is it possible to download the sources of Hotspot v1.4.2 somewhere? Is it possible/necessary to ask Sun to obtain these sources?
Thank you in advance,
Fred

Java.lang.RuntimeException: Uncompilable source code - missing method body

Hi,
I am getting the following error at runtime
java.lang.RuntimeException: Uncompilable source code - missing method body, or declare abstractwhen I try to instantiate a class using reflexion as following:
MyInstance = MyClass.newInstance(); I have tried to find some explanation using Google, but could not find any that fit my case. MyClass's implementation has a public constructor with no parameter. There is no error at compile time when cleaning and building all code.
Anyone has tips about what could cause this error?
Thanks.

Problem with registering Parser - Recompiled source code, don't see any changes

I had created a parser. I had register this parser with Ifs Manager. I had execute this following statement to see if been registered carefully:
On user ifssys/ifssys
sql)select name,stringvalue,bundle from odmv_property where name= 'p01';
I see my parser....
select name from odmv_propertybundle where id=1139;
ParserLookupByFileExtension
All it's ok. I upload a file with a 'p01' extension with option 'parser' on my Internet Explorer. All work fine.. My parser work. But I need to do some changes in my code. I update my code, recompile my code. My class file have been updated. After my parser (.class) file have been updated I upload a new file with parse option. I don't see any change I do in my code. Why??? How I can update my parser to view change. I have only recompile my code an place my new class files on the same directory. I have try again (change on code, recompile, test) and I don't see any changes.
But I have test by change my classname. My classname before is Test1 and I have rename my classe by Test2. I have compiled this code and a file Test2.class have been generate. I have update my register parser with Ifs Manager to use the new classname Test2. I have chack with sql statement to see if my parser have been updated. I have been updated correctly. I have upload a new file with parse option and I see my change on my code..
Do you have some explanations about that??
How I can update my source code of a parser already registered to the parser take the change I do.

Ok, but they have another manner to resolve this problem. If I upload a file with parser option on Windows Nt explorer (Using SmbServer or WcpServer). How I can update the class file into the JVM? I need the restart this those server or just one? If just one which server I need to restart?
Thanks Francois

After displaying result of report, my report goes back to source code edito

Hello experts,
I am currently having a big problem with my report. Here is the problem, after displaying the
result(write), when I press BACK button it is not going back to my selection-screen which is the
usual for reports. Now, what happens is that it goes back to the source code or worse, to the main menu of SAP.
What I want to do is that when I press BACK button it should go to either selection-screen 500 or
selection-screen 1500.
Here's a rough flow of what is happening in my report:
start report -> fetch records based on user input -> display results(not in ALV) ->
after displaying report, click 'BACK' button -> it goes back to source code
Now, here's what I want to do:
start report -> fetch records based on user input -> display results(not in ALV) ->
after displaying report, click 'BACK' button -> go back to either selection-screen 500 or 1500
or call again the transaction of my report.
Help would be greatly appreciated here.

Viewing the source code

hi,
I'm interested in doing some programming in Java but I'm having some real trouble just viewing the source code. First of all, I have a program I would like to look at and I have downloaded the binary files. However, after downloading the Java Development Kit, I still can't find a way to look at the actual source code. I have tried clicking everything in the C:\Program Files\Java\jdk1.6.0_12\bin file but with no avail. Is there a way to look at the actual source code? I've tried writing java but I really need examples in order to learn anything useful. Reading a HOWTO will only get me so far...
In case you are wondering, the program I have downloaded is called iFreeBudget. Like I said earlier, it's programmed in Java and I have downloaded the binary files but I can't find a way to view the actual code the programmer used to make the program.
Thanks for your time!
Mike

I've tried writing java but I really need examples in order to learn anything useful. Reading a HOWTO will only get me so far...I'm not exactly sure what you mean by a HOWTO but in addition to looking at examples you really should go through the tutorials here .
From your message I inferred that you are a complete java beginner. I think you will save yourself much confusion and trouble if you take the time to go through the tutorials.
There are code examples, instructions on how to setup and compile things, and all kinds of explanations of things that you will need to know.

Help me in finding the entry points in the source code of java.....

hi...
I want to design a compilation server and apply some of the optimization technique's like inlining, SSA and others.
So i require to find the entry points in source code from where i can include my code and check the performance of the program at level it is performing .
Please help in this problem....
and i also like to know what are hot methods in java context?

BigDaddyLoveHandles wrote:
Do you even know Java? Why not just let the HotSpot optimization do its thing?Good point, I would try either of two things.
If you have a good understanding of Java internals and are confident you could optimise code better, I suggest you contribute to the OpenJDK and we can all benefit.
Otherwise I suggest you try using the optimisation built into the compiler and the JVM.
Note: the JVM optimises the code dramatically in ways most normal people won't have thought possible.
The compiler doesn't optimise the code so much as it leaves this job to the JVM.
Two examples;
- say you call a small method often. The JVM can inline this method for you. (the same way a compiler would) However say this method can be over-ridden and later your program calls a different implementation, it can inline both methods even if the new method in a new class didn't exist when the first method was inlined.
- In a 32-bit JVM, 32-bit registers and references are used. In a 64-bit JVM 64-bit registers and references are used without needing to recompile the code. However there is a third option of using 32-bit references in a 64-bit JVM. In this case, it assumes the bottom 3 bits are always 000 so it shifts the reference down 3 bits allowing you to access 32 GB using 32-bit references. Again, you can use this with libraries which were compiled before 64-bit JVMs were available.

How to avoid "Cannot display source code at this location"?

This debugger message really annoys me. It seems to me that
sometimes when my program fails the debugger returns nice friendly
messages telling me exactly what line numebr an object is
undefined. This is great. But half the time I get message of this
nature.
at main_fla::MainTimeline/ot()
at main_fla::MainTimeline/buttMouseEvent()
Cannot display source code at this location.
Why does the debugger refuse to show the line number of the
code sometimes?
Is there acoding practice that one should use to avoid these
unhelpful debug messages?
It is very annoying when you have a 200 line function that
tells you that somehting is undefined SOMEWHERE in the function
without giving you a line number. Granted at least AS3 does
actually warn you....(unlike AS2) but I am constantly plagues by
these "Cannot display source code at this location" messages.
An anyone offer any explanation to why these messages dont
display line numebrs or how to code in a way that avoids them?
thanks

JLundan,
I want to thank you for responding to the thread I started on the forum at java.sun.com. Your solution to my problem of needing to print the code of the html pages that the file I included generates was just what I was looking for. However, I have some further questions to ask, if you don't mind. To clarify my task I should say that your rephrasing of the problem is accurate: "You wan't to display the contents of the HTML file that the web server produces in response of client's request?"
Yes, this is what I need to do, but also it needs to display the source code of that html file that the server produces in response to the client's request. Also, in this case, I am the client requesting that the server return some html file, and I'm not sure where the server is. But the webserver.java file that I shared on the forum is on my local machine. I was wondering if I could modify this webserver.java file at my home so that any html file the server returns to me would automatically display the source code. This is a school project of mine and I am stuck on this one thing here.
Further, where would I put the "foo.html" file so it can be written to?
FileOuputStream fos = new FileOutputStream("foo.html");
fos.write(bytes);
fos.close();
Thanks so much for your help. I look forward to your response, at your convenience.
Regards

Needed: A bit more info on the source code structure

Hi,
I've downloaded the source code zip file and would like to link to BlazeDS's source code from a Flex Builder project, so that I can step through it in the debugger.
As far as I can see the source code is split up in multiple sub-directories under the modules directory. It would be nice if there was a single folder that included all BlazeDS source, so that I wouldn't have to link to multiple folders in my project.
Or, at least, some explanation in a read-me file explaining what I need to link to.
Am I missing something? If so, where?
Also, an explanation of the difference between 'java' and 'java15' folders would be helpful.
Thanks,
Douglas

> Could you explain to me why flex.messaging.MessageBroker only exists in
> /core/src/java/ and not in /core/src/java15/?
Hi Douglas,
The classes are merged together in to a single jar file. The java15 code is
mainly code that needs to be compiled with the compiler in 1.5 mode. This
is left over from before we released BlazeDS and supported Java 1.4. We
expect to 'fix' all this moving forward and require Java 5 SDK and JVM as a
minimum. We just haven't done that yet.
In an IDE you can just ignore this and set the JVM level to be 1.5 and
include both the java and java15 directories as source. The Eclipse
projects (and IntelliJ IDEA projects) we provide should already take care of
this for you. It shouldn't be too hard to do in any other Java IDE either.

Performance checking inside the source code

performance checking inside the source code who to check it.
thanks and regards
chandra sekhar

I guess you are asking how to check it, then here is the answer
SQL Trace transaction ST05
The trace list has many lines that are not related to the SELECT statement in the ABAP program. This is because the execution of any ABAP program requires additional administrative SQL calls. To restrict the list output, use the filter introducing the trace list.
The trace list contains different SQL statements simultaneously related to the one SELECT statement in the ABAP program. This is because the R/3 Database Interface - a sophisticated component of the R/3 Application Server - maps every Open SQL statement to one or a series of physical database calls and brings it to execution. This mapping, crucial to R/3s performance, depends on the particular call and database system. For example, the SELECT-ENDSELECT loop on the SPFLI table in our test program is mapped to a sequence PREPARE-OPEN-FETCH of physical calls in an Oracle environment.
The WHERE clause in the trace list's SQL statement is different from the WHERE clause in the ABAP statement. This is because in an R/3 system, a client is a self-contained unit with separate master records and its own set of table data (in commercial, organizational, and technical terms). With ABAP, every Open SQL statement automatically executes within the correct client environment. For this reason, a condition with the actual client code is added to every WHERE clause if a client field is a component of the searched table.
To see a statement's execution plan, just position the cursor on the PREPARE statement and choose Explain SQL. A detailed explanation of the execution plan depends on the database system in use

Display protected source code

Hi All,
We are facing the problem of source code protection because our ABAPer deceived us and left the company.
Now we can not modify / display any program developed by him. We are logging with his id also giving same message as displayed below.
The source is protected. See explanation in long text
Message no. ED800
Diagnosis
The desired source text is protected by SAP because changing it could cause system errors.
I hope we can view this code in any diffrent way as I forgot password which I used to protect it.
Please suggest your expoert solutions.
Regards,
Ramesh.

You'll have to get your basis team involved to see the transport files. Which won't be a problem if the suggestions that it's actually you who've committed the crime are false, will it?

Where to download JVM source code? Thanks.

AhJin

Hi,
The JVM consists of the ClassLoader,ByteCode Verifier,and JIT.Now for the developing of the JVM you require to develop all three parts.But Classloader again have BootStrap Classloader,Extension ClassLoader and Application ClassLoader.Out of these you have the BootStrapClassLoader Developed in C++/C(You can check the code).
BootStrap Class Loader is basically developed for all platforms as it will load the rt.jar the basic java classes.So all the OS have different implementaion of this class loader.Rest all is developed in the Java.
Now comming to your query I would like you to check the JAVA_HOME/include directory where you can find win32 and some *.h files which are basically should be the implementation of your JVM.I am talking about the hotspot JVM.
So with the download of hotspot for windows you have source code also embeded in that.
Hope this helps you

I am running 10.6.8 and using iweb for my web site. After several SEO analysis they all indicate I need H1-6 header tags. After looking at the source code I see there are none in iweb. Is it necessary to add? If so, how do I add H Tags to iweb.

I am running 10.6.8 and using iweb for my web site. After several SEO analysis they all indicate I need H1-6 header tags. After looking at the source code I see there are none in iweb. Are they necessary to add? Why would one add these tags and how do I add H Tags to iweb? And are there examples to look at? I am slowly learning about simple web design and assumed that iweb was stand alone without having to write code. Is this one of the reasons iweb is no longer supported? Thanks for looking at this!

A simple text page like this:
Heading
    sub heading
          text paragraph ....
Is traditionally represented by html tags like:
<h1>Heading</h1>
     <h2>sub heading</h2>
          <p>text paragraph ... </p>
I would guess that the use of h1-h6 tags helps search engines to understand the structure of a page as the tags imply a certain structure.
This can be compared to more generic tags like <div> that could represent any kind of content - and may be what iWeb uses (you'll have to check yourself).
I would generally recommend that you use some kind of up to date blog/site building tool, perhaps Wordpress or Squarespace (I haven't used either one myself) that support current web technologies - this should reduce your SEO issues and make it easier to properly support mobile/tablet users.

Source code not generated in mapping

Hi,
I tried mapping an Idoc to an XSD in my mnessage mapping.When I try to check my message mapping I get an error msg : "<Mappingname> has no Source Code"...My scenario is only some fields of Idoc map to the XSD and the rest are constants..I am in XI3.
Any help is appreciated...
-Teresa

Hi Teresa,
Have you tried deleting the map and re-doing it ? Or is this unfeasible ?
Cheers
Colin
