Java and safety standards.

I'm posting this question here because real-time systems often require safety standards and no other forum seems to fit.
I'm writing an application that must be CENELEC compliant (SIL 2). Does anyone have any information on whether or not Java can be used for a SIL 2 application?
The application isn't real time but it must be 'safetied' because it is used to verify safety data.
Any help on this subject would be greatly appreciated.

Hi, not my field, but have you checked if bouncycastle supports RSA? That's a free cryptography API.
Cheers, HJK

Focus issue with CardLayout (Java 2 SDK, Standard Edition 1.4.0_01)

I am having an issue with focus and CardLayout with Java 2 SDK, Standard Edition 1.4.0_01. I have created a small sample application to illustrate my problem. In general, I am trying to create a "Wizard" that the user will enter information and then press a "Next" button to proceed to the next step.
When the first card is displayed, the focus is on the first text field as expected.
When I go to the next card by clicking "Next", the focus is not on the text field that has requested it (through the requestFocusInWindow method). The focus is on the "Cancel" button, which is the next component to receive focus after the "Next" button on that panel. I do notice that if I use my mouse to bring focus to the window the text field will gain focus.
Similarly, when I proceed to the last card, the focus is not on the "Finish" button until the mouse moves over the window.
Is there something I am doing wrong or is there a bug with focus and CardLayout?
One other problem I have noticed is that the buttons no longer respond to the "Enter" key press and instead respond to the space bar. Any suggestions as to why this is the case?
Thanks,
S.L.

Manfred,
Thanks for your reply. I tried requestFocus() and it gives the same results. Also Sun's 1.4.0 API (http://java.sun.com/j2se/1.4/docs/api/) mentions the following with respect to the requestFocus() method in the JComponent class:
Because the focus behavior of this method is platform-dependent, developers are strongly encouraged to use requestFocusInWindow when possible.
That is why I used requestFocusInWindow.

[Java and all else] How do you document DB design?

Hello,
Although most of the technical choices are explicit in SQL (UniqueKey & ForeignKey constraints, indexes,...), the semantics of the data columns and their constraints seem better served as plain human-readable comments ("ID column: identifies the plane copy; 6 figures are enough as we don't expect to sell more than 1 million planes in a foreseeable future...").
In my current system, (EJB-based, but the DB schema is not created by the JPA-compliant ORM, but via SQL scripts), I see the following ways to write and maintain this documentation:
- SQL comments in the schema creation and patch scripts
- Javadoc comments in the Java source of the Entity classes.
- UML notes in UML diagrams(1)
- external "Architecture and design" document.
All 4 of them are used, sometimes inconsistently, for various parts of the design choices; I mean, the docs do not contradict themselves (not yet, but it's a mere question of time), but some tables are commented in SQL scripts, others are in design docs, and the details for some columns are in entity javadocs. Although each developer may find it handier to "write" the doc via his preferred medium, it becomes increasingly difficult to "maintain" theoverall documentation.
Our current situation is that most of the project team members are Java developers, so it would probably be better accepted and served if we standardized that we document DB tables and columns in Java source, but I am worried that:
- someone else pouring over our DB (ex: DBA helping us to optimize things, or other team developping a data-mining tool to leverage the historical data in DB) may not be as comfortable with Java
- this may not cover all design choices of the DB schema:
- - - - first, although that is the case currently, in the future there might not be a 100% 1-1 mapping between e.g. each entity class and a DB table. Maybe some columns will not need to be mapped anymore,...
- - - - second, I fear some DB constructs are not amenable to Java counterparts; no accurate idea there, I'm not an SQL nor JPA expert, but I presume Indexes, table partitioning, tablespaces, for example (yes, the DBMS is Oracle :o) are not taken into account in JPA mapping.
And if we document those choices at the SQL level (my preferred idea so far), this will gradually make the javadocs in the entities obsolete, or removed altogether, and that will make future maintenance of the Java source risky.
How do you document your DB design in general?
Do you have specific advices for my case?
Thanks in advance,
J.

Thank you again.
A couple more questions:
2. Table, and proc dictionary maintained as one or more text files. Those files and schema are all in source control.Do you mean, a proprietary text format (a la tabledesign.txt), or +.sql+ source files? Again, you seem to suggest the scehma info is present in two locations.I didn't say two locations unless you meant files. Then yes.Yes I meant two files. I trust the team to get the doc file lagging a few revisions behind the SQL file, and to correct that I would have to include one more step in the review process (e.g. "review CM actions to check that the doc file is updated consistently with the SQL source").
The tool I wrote would throw errors if the comment file didn't match the schema. And if comments were not provided. That of course doesn't stop someone from documenting a table with "a table".
You can of course keep the addtional info as special comments in the SQL, but when I did this, and even in retrospect, it seems better and perhaps easier to keep them seperate. I have done special comments in SQL before and it seems a bit of a kluge but you do have the single source. But in that case I was the only one maintaining it too.What do you mean by "special"?For code generation I have a schema file with the following (pseudo sql.)
    create mytable
       mytable_id int,
       column_foo varchar(10);
       column_fum varchar(20)
        -- Query: for_a_query (column_foo, column_fum)
    )The generator consumes the schema and generates the standard CRUD which would include a query based on the primary key.
The above comment is used to provide an additional query where the proc is named 'for_a_query' (munged with table name) and takes two parameters (column_foo, column_fum) whose type/name matches those of the table.
If we don't try to generate a browseable HTML out of the schema (although the idea is appealing, I don't have the resource to make such a tool), do you see anything kludgy in maintaining SQL comments interpersed within DDL code?
Of course that is doable.

Java and MS-Access: Login Authentication trough SQL

We have an MS-Access database setup which we want to use as an login-database.
We can select from the tables in the database using a standard SQL query, and print out the output, but we do not know how to combine the java-string "UserID" and "Corrpass" field to compare them with the database to check if the entered login is correct.
I know this question is a little bit on the SQL side, but could you please help me? The code for printing out Usernames was founfdon the bottom of this webpage:

How do I search the downloaded Java? Platform, Standard Edition 6 API?

I am a newbie to Java (I had done some limited programming in C ++ years ago). I have downloaded the Java? Platform, Standard Edition 6 API Specification, and can view this in my Firefox browser. How can I search to certain classes in this documentation easily? For instance, if I want to ding out all of the operations available for String or System.out, etc, , is there a way that I can type in System.out, or String somewhere, and get a list of what is available?
Thanks

Brian_Rohan wrote:
Here is the code that I compiled and it worked:Yeah, "args" there isn't part of the API. It's the name of the variable that is the first parameter to the main method defined there.
The stuff between the parentheses is a list of declarations of local variables that form the parameter list to that method, to put it technically.
The thing that's part of the API is the class String. In "String[] args", the bit on the left is the type of the variable, and the bit on the right is name of the variable. A name of something you define like that wouldn't be in the API. However, the name of the class String is.
If you look at the import statements, you'll see if the name "String" is actually shorthand for a class defined elsewhere. There's this:
import java.util.*;So you can know that "String" is either defined in the java.util package, in the "helloworld" package (which also wouldn't be in the API because you're defining in there using the package keyword), or in java.lang. (The "java.lang" package is automatically imported.)
You could look in the API docs for java.util.String or java.lang.String to find the class definition. But I'll save you the time by letting you know that it's actually java.lang.String.
Again I am new at this, what would args.length be?You'll see that the type of the "args" variable is "String[]". That means that it's an array of String objects. (The [] means arrays.) Arrays all have a field called "length". This also is part of the language, not the API, so it would be in a language guide, not the API.
The value of args.length would depend on how you ran your program. When you run a program on the command line like this:
java HelloWorldor this:
java HelloWorld foo bar bazThe java virtual machine takes all the things after the class name and sticks them in an array of String. Then it looks for a static method named "main" in the HelloWorld class, and passes it that array. So in the first case above, args.length would be zero, and in the second case it would be three.
By the way, when you post code, please wrap it in code tags. Highlight it, then click the "CODE" button above the text input box.

Unable to install Java 2 Platform Standard Edition Development Kit 1.4.2_11

I am unable to install Java 2 Platform Standard Edition Development Kit 1.4.2_11 and NetBeans IDE 5.0 on Windows 98. I get the following message:
Java 2 Platform Standard Edition Development Kit 1.4.2_11 cannot be installed on your computer because current account does not have sufficient privileges.
I am trying to install at home, no network, and as far as I can tell, there is no way to give yourself "administrative privileges". Is Windows 98 not supported anymore?

98SE is supported. See configuration requirements for the various versions.
Try downloading Java and installing it, then go to the NetBeans site and downloading it and installing separately.

Java and SOAP

I am trying to use Java and SOAP to call a Coldfusion CFC file. The problem is that I can not figure out how to call the coldfusion function by using a url to direct the SOAP request, within java. The cfc file does sql queries on a separate network so I need to send a string parameter to the function and be able to return one back to the java program.
I have done a lot of internet research and I can not get it to work out right. My coldfusion is working correctly.

But the Coldfusion server would still have to present a "service". This could be using web services or it could be something as simple as a small HTTP based page to take the parameters and pass back results. Somehow the Coldfusion server must present a service for this to work.
Think of a standard HTML page with a form on it. What you're describing is similar to that - you take in parameters (the HTML form) and return results (the result from an HTTP POST). Coldfusion is acting as the web server and your Java client is acting as the browser. Until the Coldfusion server is ready to accept requests (in your case SOAP formatted requests) there is not point worrying about the client side (the Java client in your case).
Is the Coldfusion server presenting something that can run the CFC file and return the results? Again, it could be a web service or even a REST-like service (like I described above) that your client could talk to.

[Java and all else] Requirements tracking, testing, and versioning

Hello,
as a semi-experimental subject, I am considering managing requirements and test documents in the same version control system as the code.
For some reasons, this versioning policy doesn't seem mainstream, so I'd like to have your opinion on that.
+N.B.: the prefix "java and all else" refers to the fact that I'm using this area to post a message that is related not only to Java but also to other topics (people, processes, tools,...) that help program in Java - so this post is not really off-topic either. For the record, I filed a suggestion to open a dedicated forums to discuss topics like that, although it hasn't received enthusiastic support so far :o(...+
Here is how I had imagined to proceed:
- requirements document gets edited and stored as text in the VCS
- test plan (basically a matrix of which tests cover which requirements) goes into the VCS as well, text or binary
- test instructions (detailed steps, actions, expected results) are stored as text in the VCS
- test results - I do'nt know yet, but I planned to store them as text (lists of testId=result) in the VCS (I'm not sure indeed, that those would go into the VCS)
The advantage of versioning those as text is that all VCS clients support easy-as-a-click history browsing and diff capabilities.
Diffs and logs are useful to trace when and why a requirement has appeared, evolved, obsolated,... Especially in long-lived systems whose maintenance crew rarely embeds "historical" pioneers who developed the original systems.
My questions:
1) Is it good practice to version such docs in the same repository as the code?
I've never seen this done.
- In half of the shops I've been these docs are not really versioned (the PM considered it enough that the latest applicable version of the docs was available)
- The other half has used versioning systems ranging from ad-hoc (shared folder acting as repository of all versions) to "document management systems". I found such tools to be developer-unfriendly (poor diff capability, poor text searching), and developers to be office-document-reluctant (mostly because of the shortcomings of the doc format and doc management systems).
- The third half <wink to aficionados of French cinema> used dedicated softwares (Test Director, RQM,...) to manage requiremetns, test plans, test cases, test results,... The drawback is that the developers were hardly involved in using such tools, and even when they were, were not trained to use the administrative and metadata capabilities (who modified the test steps, when and why?).
On the contrary, developers would easily and gladly browse histiry, check diffs, etc... on text documents versioned using their daily-used source control system.
2) Are there "standard", preferrably text-based, formats, for the documents listed above?
Each and every organization I've seen had its own format, but most items have equivalents in all organizations, even if disguised under different terminologies. I have no formal education or training in quality assurance, but I guess some ISO or CMM norms define those recurring items, and I expect some abstract XML format might exist
3) Are there tools already that cover edition and exploitation of such formats, or why not, of the versioning of such formats (naive example, graphing the pass rate of tests over time)?
A pet project of mine is to develop and open-source some Swing UI to do this, but existing tools would save me the trouble.
I'm looking forward to reading about your own experience.
Best regards,
Jerome.

Fixed link.

I don't have data on comparative bug rates because we did not do studies focused on that. This stuff was mostly driven by convenience #) considerations.
Subjectively, yes it seemed to have lower bug rate compared to maintaining documents in, say, pdf format (like our doc writers did with User/Dev guides). BTW doc writers are another kind of guys who dislike plain text.
As for using test results history the way you describe - agree, that makes some sense. Now that you mention it I recall using it myself that way, in one of the projects where testers managed to establish really convenient way to assess test execution history. After I figured how easy it was, I began using it. Quite helpful indeed.
Regarding "tool or format that mapped tests to specific requirements" in your original post - did you consider Polarion? IIRC it supports mapping requirements to test descriptions. Telelogic DOORS are maybe also capable of that but I am not completely certain.
#) convenience -- BTW we maintained test descriptions not in plain text but in simple HTML (you know few tags one can use in javadocs). With limited line length, it is almost as VCS friendly as plain text, even with tables:
<!DOCTYPE "stuff to make HTML validator happy">
<html><title>test description</title>

Basic question about storage and safety in iMovie '11

A very basic question about storage and safety:
I want to keep a backup of my raw footage on my external hard drive prior to begin working on the movie in iMovie. I want to do this:
1. Upload the digital files from my camcorder to my Desktop *(as opposed to iMovie)*
2. Duplicate that footage/clips.
3. Put the duplicate clips/footage into a folder labeled with the name of that footage (like "Fun At the Dentist" or "Jimmy Learns How to Yodel").
4. Drag the folder with the footage/clips into my external hard drive into a pre-existing folder titled "Backups/duplicates of all of my raw footage/clips." This big granddaddy folder will house all of the child folders of different movies.
5 Then, open up iMovie '11 and import the raw footage/clips from my Desktop rather than from my camcorder.
6. Then I want to make a duplicate of my finished movie and put it in my external hard drive in a "Finished Movies" folder.
I know that the original raw unedited footage will always be in iMovies '11 but I want the original to also exist immediately accessible in my external hard drive.
QUESTION:
Is this viable? Is it wise? (I know it goes an extra unnecessary step, but aside from that.)
*Do you have any precautionary advice?* Should I do something in my iMovies '11 preferences? What?
In earlier years with iMovie '04 or '06 (cannot recall) I made many novice errors and ended up losing audio to my finished movie. I also lost footage.
This time around with iMovie '11 I don't to make such novice, ignorant errors.
Thanks so much for any comments to this question.

Yes I'm sure it will work great for you.
The iFrame format is something Apple has come up with. The reason for its existence is unknown to me so I can only speculate. But it seems to me that Apple "invented" this format in order to have devices such as Ipod/Ipad/Iphone/Ixxx create clips that are editable on consumer hardware such as already mentioned devices but also standard Mac computers, without the need for format conversion.
iMovie converts most input formats during import, which takes a lot of time, and this need for conversion often comes as a surprise to most people new to home video editing.
iFrame has a resolution of 960x540 which is long way from the common standards of 1920x1080 and 1280x720. If your end target is YouTube however, this may not be too bad though. However if you intend to go with YouTube HD, you may find iFrame footage to look wrong since they are effectively upscaled to a higher resolution.
Technically iFrame uses the H.264 algorithm, a smaller frame size (960x540) and a rather low compression scheme. This will result in large files, but the plus side is that the files are ready for editing without the need for any conversion and iMovie will natively edit the files.

UI Design and ISO standards

I am looking (without success) for an ISO standard, issued papers, or similar standard that spells out HMI design issues, especially with regards screen formats, best backgrounds to use, etc.
Any suggestions?

A good starting place is BS EN 60073:2002 - Basic and safety principles for man-machine interface, marking and identification. It makes reference to a few other standards but I've not been through any of those myself.
If you've got access to a good library, have a gander at the Encyclopedia of Human-Computer Interaction. It's pretty hefty, but it's an excellent reference for anything UI related.

Difference and advantages of java and c++

whats the best advantage of java over c++
also the basic difference between java and c++
what the difference between multithreading, multitasking and multiprocessing
what if there r 2 main methods in 1 java program with different signature
difference between method overloading and method overriding

whats the best advantage of java over c++Java is simpler.
also the basic difference between java and c++Java is easyly portable. It has a GUI (Swing), multi-tasking and garbage collection as standard.
what the difference between multithreading,
multitasking and multiprocessingMultithreading is mostly used at the language level to mean many threads of execution. Multitasking is mostly used at the OS level to mean many processes (program units) runing at the same time. That should cover multiprocessing too but here processing can also be used in a broader sense at the application level to mean any "process" you can think of.
what if there r 2 main methods in 1 java program with
different signatureYou'll have to specify which one you want executed I guess. Try it out!
difference between method overloading and method
overridingOverloading is a convinience facility. It allows you to let methods in a class have the same name as long as their signatures differ.
Overriding is when a method defined in a superclass is replaced with a new one with the exact same signature in a subclass.

Personal Java and Jeode??

Once there is no Personal Profile available for Windows platforms, one solution I've heard about is using Personal Java and Jeode VM.
As I can see, Jeode is a very good VM and supports some versions of standards Java versions..and Personal Java is no longer supported by Sun, but it's functional.
Is there anybody who knows wich versions are usable? Looks like jdk 1.1.8..is there one newer?
Any help appreciated.
Thanks
Ricardo

There is a certified Win32 (and PocketPC) version of Personal Profile available with IBM's WSDD 5.6 Tech Preview. See:
