Building java applications using UML

Hi all
I want to get experience for building java applications using UML.
Pls advice what is the best text book should I purchase??
thanks
madura

I do not use UML to auto-generate codes either. Take a look at Martin Fowler's bliki on some quite good views about UML: http://www.martinfowler.com/bliki/uml.html
What I do use UML for:
1. To visualise the system being built during the analysis and design phases - both to help improve understanding and to keep the stakeholders happy.
2. To reverse-engineer existing code that's weak on both design documents and code design. Makes understanding the code easier.
3. To highlight areas in existing code that might benefit from the application of design patterns.
As for how UML converts to Java code, the main diagrams are the Class Diagram and the Interaction Diagrams - Collaboration and Sequence. These diagrams translate to code very well.

Problem Web Dynpro Java applications using JasperReports

Hello all,
We have followed the footsteps of these blogs but we can not make it work.
Part I --> Part-I: Print Web Dynpro Java applications using JasperReports
Part II --> Part-II: Print Web Dynpro Java applications using JasperReports
Part III --> Part-III: Print Web Dynpro Java applications using JasperReports
Details system: 7.02 SP3
We believe that the problem is in the library, because it finds them.
1) We created project as a DC external library with *.jars
2) Public part DC external library.
3) Add public part of DC Library into new project DC WebDynpro Java.
4) Development Component -> Build is OK
5) Development Component -> Deploy is OK
6) Test app ERROR.
When we run the application shows the error:
The initial exception that caused the request to fail, was:

Hello John,
Thanks for the link. We have performed the steps in this blog:
1) Create DC Project "External Library" with name js/jars:
- Add *.jars in folder Libraries.[Screenshot Libraries|http://img846.imageshack.us/img846/8395/jsjars.jpg]
- Add archives (*.jar) to public part with name ExternalLib. Which option to choose?
a- Provides an API for developing/compiling other DCs (Option chosen)
b- Can be packaged into other build results (eg SDAs)
- Development Component -> Build
Step 1 is OK.
2) Create "J2EE Server Component / Library" DC with name js/lib:
- Add Used DC -> public part project ExternalLibrary -> "ExternalLib"
- Specify both build time and run-time dependency here and strong.
- Generated SDA file in <var>gen/default/deploy</var> How do we check that it contains <var>js.jar</var>?
- folder gen/default/plublic/defLib/lib/java then you meet *.jars files again. is OK.
- Development Component -> Deploy.
- Go to Visual Administrator. We found the library js/lib, but has no associated *. jar. It is the problem.[Screenshot Visual Administrator|http://img542.imageshack.us/img542/5537/visualadminlib.jpg]
3) Create "WebDynpro" DC with name pdf_jasper
- Add used DC (defLib) to WebDynpro DC with option "Build time".
- WebDynpro References -> Library references --> add <var>jslib
- Deploy
- Run error: java.lang.NoClassDefFoundError: net/sf/jasperreports/engine/JRDataSource

@OP. You could have clarified your original post and the relationship of your question to java. You did not need a new thread.

Building ADF application Using Maven

I have a requirement to build the Adf application using Maven.
My JDeveloper version is 11.1.1.3 and I imported the Maven plugins.
When I create the new Fusion application , pom.xml is getting created in model project but not in viewcontroller project. Any reason for that?
Please help me to point to the right article and example to build Adf application using Maven?

User,
While you can build an ADF app using Maven, it's nowhere near easy or automated in terms of getting started. There are a few people who are doing it, but they have invested a lot of effort including:
* loading the ADF libraries into their corporate repositories
* re-structuring their ADF projects to match the Maven directory standard (or customizing their POMs)
* Hand-building POMs for their ADF apps
Most or all of the people that I know who are doing this are doing all of these things without the benefit of the Maven integration provided in JDeveloper. If you have a search of this forum and the [url https://groups.google.com/forum/?fromgroups#!forum/adf-methodology]ADF EMG, you can find plenty of discussions about this. There's no "step-by-step" guide that I know of, and it will definitely take you quite a bit of effort to get started. The Maven integration in JDeveloper is still in developer preview mode, and in my opinion, isn't ready for prime time - at least not with respect to ADF projects.

Can we run a java application using Runtime.exec()?

Can we run a java application using Runtime.exec()?
If yes what should i use "java" or "javaw", and which way?
r.exec("java","xyz.class");

The best way to run the java application would be to dynamiically load it within the same JVM. Look thru the class "ClassLoader" and the "Class", "Method" etc...clases.
The problem with exec is that it starts another JVM and moreover you dont have the interface where you can throw the Output directly.(indirectly it can be done by openong InputStreams bala blah............). I found this convenient. I am attaching part of my code for easy refernce.

Deploying no java applications using Java Web Start

Hi,
I am new to java web start. Is it possible to distribute non java applications using java web start. I have an APP which can run on a desktop in standalone mode. The app has jusy HTML and Java script files. Is it possible to package this app and deploying using java web start? I am assuming If it is possible, I can make updates to the packaged app in the web servers and the updates will be downloaded next time the app is used provided configurations are correct?
thx

The app has jusy HTML and Java script files. Is it possible
to package this app and deploying using java web start? Not really. Resources for JWS need to be zipped,
while this HTML/JS app. will (I guess) not work from
inside the depths of a Jar (or Zip) archive.
Note that you can organise for those files to be
downloaded and expanded onto a known place
on the user's disk, by using an 'installer' element,
but..
...I am assuming If it is possible, I can make updates to the
packaged app in the web servers and the updates ..installers are only called once, and do not 'update'.

Load java applications using PXE or bootp

hi... i was trying to test the option of booting up a java application using PXE or bootp.. is it possible to do so?? what are the rcommended ways to do it??
Thanks

Normal CORBA (as in Java IDL) is probably way too complicated for what you're trying to do, unless you're thinking of someday having the programs talk with non-Java programs.
I'd start with Java RMI rather than RMI-IIOP since you can probably find more tutorials and docs on it (though the RMI-IIOP 1.4 docs here are really quite good). That way, you're writing everything in Java, at least.
For remote object systems, all the advantaged of object oriented programming come into play, especially extensibility. What if you need to change the wire format to add more information in your socket system but need to maintain compatibility with older clients? What if you need to add security or handle multiple clients at once? What if you'd rather rely on existing serialization methods rather than code your own wire format for everything you want to send (making you write more code)? You can serialize any Java Serializable over Java RMI. That lets you send things without violating encapsulation. What if you want to talk to programs that aren't written in Java? What about automatic failure recovery if the server crashes? etc etc.

Error while running Java application using Crystal Reports 2011

Hello,
I would like to ask for your help.
Environment details:
Java based standalone application in Development environment.
Crystal Reports 2011 (no SP applied)
Oracle 11g ( 32 bit client installed)
Win7 64 bit OS.
Workflow:
While running the java application, which will display the reports I am getting the below mentioned error. I guess that is because I am missing the Crystal runtimes (Correct me if I am wrong).
I know that CR2011 do not have any sdks/ jar available for deployment. In this case, which runtimes should I be using? Does installing CR2011 be enough in the development box?
Please provide me the link from which I can download the same.
Let me know if I need to provide more details on this. Any suggestions are most welcome.
Thank You.

Can i develope a java application using C API

hai,
i have C api, the project was developed in C before, now i am having that api. I have to do that in java by using that C api.
can any one suggest me how to do this?

Your question is not that very clear!! You want to convert the C api to a Java api? or you want to develop a Java application that uses the C api?
For the first question I believe that you should check the functionality of the C api and re-code it in Java! do not believe you should find anything imposible in that! (unless that api is trying to do something crzy directly with memory)
For the second question then I believe you will have to use native calling or something like that. I have never used it, but read about it, and it seems one way how Java can interect with C.
Over here there is a forum.

As java API support the MethodEntryEvent, using which I can get the automatic logging statements when the method is entered or exited as HelloExample.main(with argument type).
Where HelloExample is the class name.
Main is the method entered with its argument types.
In some cases I have the o/p as
-- VM Started --
====== main ======
main -- HelloExample
callerMethod -- HelloExample
====== main end ======
-- The application exited --
By using Log4J is there any possibility of getting these sort of o/p along with the loggers supported by Log4J. i mean to say can i built an java application which supports the MethodEntryEvent and MethodExitEvent from java API and also uses the Log4J debugging. I took an e.g. trace example, which (in J2SE 1.4.x or 5.x) will be found in $JAVA_HOME/demo/jpda/examples.jar and unpacking it by
jar -xvf $JAVA_HOME/demo/jpda/examples.jar i found the com/sun/tools/example/trace/Trace.java and passed the class constructed with logger taken from Log4J. In this case the logging message is displayed on the console. As per the requirement i need to transfer the whole o/p to an output file along with Log4J logger statements. in this case i should not give any command in the cosule except compiling and executing the programme. the programm also should able to run without the main() as i need to integrate Log4J with an application and the code must me application server independent. i need the output as i got using MethodEnteryEvent (shown as above) in case of java application built using Log4J.
Can any one help me in this regard. can any one give me some suggestion or any programme of this sort. All suggestions are welcomed.
Thanks & Regards,

hi,
can someone help me how to implement logging for method entry parameters and
method exit return value.
can someone help me how to use log4j and integrate it to the method entry
logging and method exit logging.
Here what i need is without writing the log statements for the method entry and
method exit i need to log it to the file
along with other log4j debug statements i provide in the file.I should be able
to configure whether to enable/disable the logging
for method entry and method exit. In method entry i should be able to log the
parameters the method take and in method exit
i should be able to log te return value to the log file, before the method is
returned to the callee.
i hope i am clear
Thanks in advance.

Issues while configuring java application using JDO with MS JDBC Driver 1.0

We are in the process of configuring our java application with the production version of SQL Server 2005 Java Database Connectivity (JDBC) Driver 1.0. We are facing issues getting it to work with Sun App Server using JDO concept.
After creating the data store, adding the JDBC driver to the application server classpath through console and also copying the driver into the lib directory, we are still getting the below error.
Following is the stack trace encountered while running the application

Can anyone help me on this issue?

I have already tried this before and this not work too, but strange that even if I use JDBC:ODBC bridge driver, the return value for output parameters are not correct, that is, only return the value that I input but not the value after executed in the procedure....
The code that I used with JDBC:ODBC bridge is as follow:
public static void main(String[] args) {
String url = "jdbc:odbc:;DRIVER=SQL Server;Persist Security Info=False;database=db;Server=sql;uid=sa;pwd=pwd";
          Connection con;
          ResultSet rs = null;
CallableStatement callS = null;
          try {
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
          } catch(java.lang.ClassNotFoundException e) {
               System.err.print("ClassNotFoundException: ");
               System.err.println(e.getMessage());
          try {
               con=DriverManager.getConnection(url);
callS = con.prepareCall("{ call dbo.CpJavaTest (?)}");
callS.registerOutParameter(1, Types.INTEGER);
callS.execute();
rs=callS.getResultSet();
int ret = callS.getInt(1);
System.out.println("return value : " + ret);
               while (rs.next()) {
                    String f1 = rs.getString(4);
                    String f2 = rs.getString(5);
                    System.out.println(f1 + " " + f2);
          } catch(SQLException ex) {
               System.out.println("SQLException: " + ex.getMessage());
The value of the output parameter is same as what I inputed! Hope any one can teach me how to correct it...
Thank you very much!
