Java Development for PDA

Hi all,
I intend to develop a multiplatform application that enables communication between devices using i.e. 802.11b. This application can be installed in a Laptop or a PDA. The application will use basic stuff like sockets and will perform most of all data management. There is no need for a GUI.
The test environment i have right now is a Laptop running Windows XP and a HP iPAQ Pocket PC H5500 Series (Windows Mobile 2003).
Since this kind of technology is totally new for me, The last couple of days i searched the internet in order to see which tools i would need in order to develop this application. The idea is to write the code once and the same code can run in these two devices. After all these days i still didnt find a concrete development platform for my application.
My question is:
Which VM (IBM J9, crEme, Jeode, etc..), Specification (CDC, CLDC, MIDP) and Profile ( i.e. Personal Profile) will be best to use?
thank u for your time,
CrisBento

there's no CDC profile for the Palm OS (not that i heard of) and since you are not using any GUI..i would stick with CLDC and Foundation Profile.
As for VM...IBM supports for the Palm OS and Pocket PC and cost about $5-$6 per VM (but you have to buy in bundle). Other VM iis a bit more expensive..Jeode is rather fast, but again expensive.
Newer BlackBerry comes with a Java VM (CDC + Personal Java Profile, i believe)

Basically you have a 99.9 percent Window's install so any Windows software issues are Microsoft problems.
The only thing I can think of is the Microsoft servers were down briefly for maintenance or problems or maybe had a heavy load. If you were using the Auto update try going to the web site directly as they should be on another server.
You might also try the Microsoft Window XP forums and see what you can find. Maybe search for: "Security Update stalls"?
From what I've read just turning virus protection off doesn't work sometimes, you may have to UN-install it to get it to work.
"Permissions" pertains to MAC SOFTWARE only. 3rd party software or Windows files are NOT affected at all by running permissions. Besides, it will only work on a HD with a Mac operating system anyway. You can't even select the Window partition in permissions to try it anyway.
Good luck....

Java application for PDA

Hi,
Can you recommend which is the best PDA (or graphic tablet) for Java development.
I need to develop a simple application : a data entry form to be filled in. The form does not really require keyboard input, just options to be ticked.
I thought this could be developed as a Java Interface.
I was also considering a graphic tablet for this application because the screen space is bigger.
Id be very grateful for any suggestions or tips of what my best options would be.
Is there a more specialized forum for this subject (I havent been able to find one)?
Thanks very much

a better question is: which PDA has a decent JVM installed. There are not many. I would consider .NET mobile if I were you, combined with a Windows Mobile 5+ PDA. You'll have far less head aches.

Good Resource for Finding Java Developer for Startup?

Not sure if this is the appropriate to place to post but we are looking for an interested Java developer to come onboard our very small (2 man) startup to help us with our networked Java application.
I have looked around a little online and not found much so does anybody know where is a good place to scout out such persons? Admittedly we are not flush with $ but we do have some and we would be providing equity along with ongoing cash payment. Of course we also understand we won't be getting the best Java guru out there but then we don't really need that either, just someone capable of simple socket programming, swing and basic SQL stuff. Not rocket science, and we would even consider less experienced developers with a keen interest to learn and use this as an opportunity to develop some new real-world skill so their own. We are very laid back.
Any help appreciated.

I'd try one of:
Your local Entrepreneurs meetup
- there's bound to be one, and people who go along to this sort of thing will either be able to recommend someone or you might even meet the right sort of Java dev there.
The Joel On Software jobs board
- because the right sort of people read Joel On Software
Personal recommendations
- because that's always best; if you're not asking around like crazy, you should be.

DBA or Java developer for relatively new in this field.

I`m good PC user with 10-15years of experience in : (did make some website from scratch ) html c++ know adoby tool set and can use it, also I know pc`s as a technician can truck and solve most of the problem in PC`s.
So I`m saying I have some skills mostly like user with knowledge and passion to learning something new. Newer worked for any IT company.
Now back to my question now I do better then anyone in our group (may be cause I know English better and can study at home or I have more experience in MySQL that providing me with some push that helping me).
We soon have to chose direction of study one DBA another one Java and Weblogic but im 32 already and rest of the group relatively young.
1) First what shall I pick with my previous experience to have any chances get job.
2) Dose I have any chances at all get job in IT cause i believe im too old to start new career in IT , all this study at least will be 1,5 year long may be this is just wast of time and money ?
Thanks for any reply and your opinions.

Discussion: Why no centralize development for Java (like the one in ABAP)

I am reading the NetWeaver Development Infrastructure, and noticed that due to the distributed development nature of Java, SAP recommend The Four-System Landscape for the development lifecycle.
Each developers has their own local development environment, that's why it is necessary to 'reconcile' the environment using one more layer of system. Although they checked out the particular Development Object, the necessary library from the central is being copied by DTR to the local environment. However, there are still possibilities that someone changes the library, or other classes that being refered. And we are not talking only about the business logic, but other object in the persistance level too. Let's say your program refered to a certain field in a certain table, but someone else had changed the field name. Or even worse, you want to get the setting value from a certain setting table, but someone else had deleted the value of that record (for whatever reason).
In short, I believe there are many 'reconcilliation' process that need to be done when the development environment is not centralized. These problems won't happen in the ABAP world, because you will notice the problem straight away when you activate your component, or test run it. In distributed environment, you will only notice it when you check-in your development object back, but it might be after some time lags, and you might not remember which part need to be taken care of.
Not only this, the setting of 'correct' IDE environment in each local PC must be done properly. Again, in ABAP you just need to install SAP GUI and it will be your development environment.
So, I had discussion with a friend of mine, and he asked, why there is no central development environment, like the one in ABAP? Hmm, to be frank, I also don't know. Performance problem? I notice that most IDE in the market based on the assumption that development will be done locally. Or is it for the convenient purpose, so that people can keep the development eventhough there is no connection to central server? But what is the cost for this convenient?
What other people think?
rgs,
Hiroshi
ps: As you might notice, this thread is not marked as question. I am just curious of what other people think about this issue. There will be no points rewarded for the replies.

Hello Satya,
So if it's a 'mere' technical limitation, then there should be a way to create centralized development for Java
It might be an old mainframe environment, but from the development process point of view, centralized environment offers benefit where lots of versioning problem (library or data dictionary) can be solved.
I used to work in a distributed development environment to create a web based FI/SD/MM related application. We have tons of classic problem of '<i>it is working in my environment, but not in yours</i>' type of thing. With centralized (read: ABAP), version integrity problem can be reduced to minimum.
For the NWDI itself, I think SAP now moves toward embracing the open source platform to support the development environment. From what I've understood, Ant, for example will be used as the build tool. My personal opinion is, better if SAP creates it's 'proprietary' environment to centralized the java development process. Then it will save lot's of hidden cost during the implementation of new application/enhancement/maintenance in the whole supply chain.
rgs,
hiroshi

Flex for Java Developer?

I am working on flex 1.5 from last 7 months.Ealier i hv
worked on Java (1.5 Yr)
I hv created an application in flex sucessfully.
My Qtn is:
Whether i have to continue with flex or move to another
technologies like Struts etc.
Because i have nil knowlwge of FLASH.
or
I hv to start learning FLASH MX. Is it necessary for
Flex/Java Developer.
I am comfortable with action script if uses for Business
Application but
unable to produce better designs using it.
Please Suggest.
with Regards
Vinay

well vinay if u r thinking about -- Flex Front End to Your
Struts Applications
then ,,
Struts is an open source framework that facilitates the
development of web applications based on Java servlets and other
related technologies. Because it provides a solution to many of the
common problems developers face when building these applications,
Struts has been widely adopted in a large variety of development
efforts, from small projects to large-scale enterprise
applications.
Although Struts greatly facilitates the task of developers,
it doesn't do much to improve the end-user experience: the
end-result is still an application delivered in HTML and using the
traditional HTTP request/response mechanism.
Developers—and organizations in general—are
increasingly looking for solutions to provide their applications
with a more engaging user experience that overcomes the limitations
of HTML.
Macromedia Flex is a presentation server that addresses this
requirement and allows developers to build a new generation of Rich
Internet Applications (RIAs) that combine the usability of desktop
applications with the reach of traditional web applications.

Oracle database 11g certification for Java developer

Hello,
I'm Java developer, OCPJP 6 ( Oracle Certified Professional, Java Programmer +6+ ) and
I decided to pass exams: 1Z0-051 and 1Z0-052 to get OCA ( Oracle Database +11g+ Administrator Certified Associate ) certificate,
but I need some advice, maybe i should seek other certificate, that would be more valuable for Java developer, than OCA.
Thanks for advice.

The answer of whether a particular certification is valuable depends on you, not the tests themselves. The Oracle Certified Master for example is an extremely prestigious certification, and I have considered seeking it at some point in the future to improve my professional credentials. However, the same certification would have absolutely no value to my wife, because she's a homemaker with no interest or intent of ever working with Oracle.
Using an example a little closer to yours, only reversed --- I work as a DBA and PL/SQL developer. On several occasions I have dabbled with Java, and took a couple of classes when I worked for Oracle. I could code in Java if I had to, but wouldn't really be good without a lot of practice. However, I've never really had a sufficient need in my work to dig in and really practice enough to use it. I considered going for the Oracle Java certifications as a means of kick-starting that and getting to the point where it was really a viable option in my development. Ultimately I decided not to because I've been working with Oracle for better than fifteen years and there has never been an occasion where I really felt a need to know Java. If I were to spend a bunch of time improving my Java skills just for the certification, there's no guarantee I would ever use them after that.
Coming back to you -- if you already need SQL and DBA skills in your work, then those certifications should be of value to you immediately. If you think that you might work (or want to work) more with SQL and DBA-level skills in the future, then they should be of value to you in the future. If you won't use the skills now or ever, then the exams do nothing but add a line to your resume (which still has value, but you must determine how much).

Java extension for SQL Developer 2.1 (SqlEditor)

Hello,
we are developing a java extension for SQL Developer. It was working fine in version 1.5.5 but it seems that some of the java classes were changed in version 2.1 so it does not any more. In the SQL editor, we want to have a context menu action that gets the selected SQL statement and calls a database function with it as an argument. Our code looks like
@RegisteredByExtension("our.developer.extension")
public final class OurCommand extends Command {
public int doit() {
SqlEditor sqlEditor = (SqlEditor)getContext().getView();
String query = sqlEditor.getView().getSqlStatement();
sqlEditor.executeSql(query, "");
//or
//sqlEditor.getView().scriptRunner(query);
Unforunately, in SQL Developer 2.1 the class oracle.dbtools.sqlworksheet.sqlview.SqlEditor does not exist. Does anybody know how to write this example for version 2.1? Is there an API documentation (alas, [http://wiki.oracle.com/page/SDK+2.0] is an empty article)?
BTW, does anybody know how to open the dialog for connecting to a database when sqlEditor.getConnection() is null?

I got it to work using a BASIC call instead of my normal TNS call.
We use MS SMS to package the Oracle client and SQL Developer and push it out to users so we don't have people visiting desktops. Also, we use OID to store the entries instead of a tnsnames file so that we don't have to maintain a TNSNAMES file.
I am testing 2.1 as we would eventually upgrade when it goes GA.
2.1 seems to be built on Oracle 11g. Issue will be that since 99% of our databases are 10gr2 as well as 100% of our client population will be be forced to upgrade the Oracle client to use 2.1 as we do today without lots of changes for the end user?
We don't broadcast the information the average user requires for a BASIC connection so that is out for non technical users..
We have SQL Developer 1.5.5 right now and this is not and issue.
Hopefully, this will be resolved during EAI for 2.1.

Database access tool for Java Development

Hi,
A couple of days back, our SAP's database (MSSQL) was corrupted and downed the Java Stack.
During the Java development, normally after a newly created table was deployed via Java Dictionary, Java developer will access the database via the MSSQL Enterprise Manager to view/delete/update data. Unlike the ABAP development, all database access was done via SE16 in SAPGUI. It was believed that the Java Development kind of direct access to the database via the MSSQL Enterprise Manager was causing some MSSQL tables to be corrupted, and thus downed the Java Stack.
1. Is there any tool like SE16 to access database during the Java Development?
2. If no, what kind of recommendation/tool to access database for Java Development?
Any help would be much appreciated. Thanks.
julius

Julius,
There are no industry recommended open source DB tools.
Normally it depends upon the developer preferences that how he/she wants to see the tool usability.
I can suggest you to go through the below link:
http://sourceforge.net/search/?type_of_search=soft&words=SQL+Tools
You can find many open source SQL tools, which you have to test and select one among them.
I can suggest you to use:
1) TOra
2) Easy SQL
3) SQuirrel
"Choose a Tool which is easy to use and efficient, Dont worry about Look n Feel"
Best of Luck
