Java expertise in XI ?

Hi Guys,
I am working in XI and i have ABAP back ground and i am planning to learn java and can some body suggest what are the areas in Java needed for an XI developer.
any links for the java turorials and suggestions to learn and expertise would be appreciated
Thanks,
Raj

hi,
As chirag told u need to check all the points which he as metioned and i need to add some more points...
For creating simple UDF u need to have corejava is ok....to develop the adapter module,PGP module and FTP module u need to have very good knowledge.......for Lookups also u have to write the java code.....
so if u want to come to XI it will be better to have good Java back ground or learn java.
Now a day client requirement has been changing so u need to deveop PGP for Bank interfaces......
check some links iam sending on sample UDF code u will getr a idea.

  • Questions about expected Java expertise

    Hi,
    For last 8 years I have been doing multimedia and web programming using Microsoft technologies. I have seen a job which is asking for a minimum of 6 months of experience in developing applications using Java 2 platform. They expect to have experience with Java Swing, JSP, J2EE, PowerBuilder, RDBMS, UML, HTML, XML and ASP.
    It seems that they have web and non-web applications. Can someone tell me what kind of expertise someone with 6 months of experience will have with Java 2 platform keeping in view the above information?
    I am comfortable with ASP but new to Java world. If you were conducting interviews what level of expertise would you expect?
    Thanks for your time and comments,
    Green

    It seems that they have web and non-web applications.It mostly seems like their HR department has no technical knowledge. Which is expectable.

    I am comfortable with ASP but new to Java world. If
    you were conducting interviews what level of
    expertise would you expect?In your case? Knowledge of UML and general development practices, knowledge of the stuff you did and the ability to learn Java.

  • To all java expertise

    Dear All,
    I hv database issue, first i made my database connection as a application session so can share among all the user in one web application. so, user will share same database connection for SQL query, update or edit.
    Does anyone try this before and what is the impact would be?
    I always receive this error before once a while and do you think it is related to the shared database connection?
    java.sql.SQLException:
    [Microsoft][SQLServer 2000 Driver for JDBC]Connection reset by peer: JVM_recv in Socket input stream read

    >
    well, let me start (again) by saying this is just my
    OPINION (I have been flamed once too many on this
    subject...).
    I would say EJB technology is somewhat overrated, and
    then mostly the container managed ones. There are two
    types, container managed and bean managed enterprise
    beans. The container managed beans tend to slow down
    an application alot once the dataload increases and
    the datamodel gets more complicated. The amount of
    objects involved in database activities is huge. Using
    bean managed beans could remedy this, because you've
    got total control on how the data is being
    loaded/written, but even then, the overhead caused by
    the whole container thing is alot. Now don't get me
    wrong, for the bigger projects it's perfectly OK to
    use the beans and an application server, but for
    smaller projects (like the one you're in right now),
    I'd definitely stick to using your own 'framework'. If
    the design is good, you'll end up with a extensible
    web application (maybe not as easily extendable as an
    J2EE application, but that's hardly a guarantee
    anyways...). For the most part (and this is where
    people start to flame me) I think resorting to EJBs is
    nice if the developers on the project are of the
    'point and click' type, rather than the
    'dos-edit/javac' type. That's not to say that the
    latter type is better, but they would be better able
    to judge whether an application needs to be
    implemented using EJBs or just a good framework.
    Hope it helps ?
    Rishiseems getting to learn some real experience frm Java consultant. But i know there are always a room for improvement for any system.
    At this moment, i just concern about the sharing connection from session application layer. Logically, this could
    1) Saving the open/close connection time. It should be significant better performance if each time user connect across WAN using sharing session connection compare to open/close connection each time of user query to database.
    2) Coding will be much more simpler, especially exception handling for opening JDBC database.
    3) one way of not putting the database ID and password into every JSP or servlet page whenever wanted to connect to database. Somehow i feel sharing connection from application session is much more safer cause database id and password is only initialised once.
    Anyone got better ideas or correct my mistake..is welcome

  • Biochemist in desperate need of Java expertise!

    Hello People
    I'm a Biochemist, with no programming experience at all! I have an assignment where I have to create a programme whereby I store an array of different values for an amino acid (single char); I then paste in an amino acid sequence (a string) and using an equation, take each char and add them together and the result will tell me if it is ordered or disordered; basically I want to convert the string into chars and apply the equation and then add it up; I also have to create a GUI and applet (whatever those are?)
    could any of you help me in any way? some script I can play around with would be fantasic!!
    thankyou in advance

  • Passing XML from Java to PL/SQL using CLOBs?

    Hi. Here at the University at Buffalo, we're trying to develop an architecture where departments can send XML transactions to the business offices over HTTP. Since we don't have much Java expertise on staff, the boss has decided that we should use PL/SQL wherever possible. To that end, I have a Java servlet that calls PL/SQL stored procedures using JDBC.
    My question is this: We anticipate that we will have the need to process documents larger than the limit on VARCHAR2 data. However, unless I am misunderstanding the documentation on working with LOBs, the LOB itself must already exist in the tablespace. How will I take the XML document I receive through the servlet and pass it through to the PL/SQL function which accepts it? This function, FYI, routes documents to various systems based on document type, checks user security, and does a bunch of other things before the XML document is committed to a table.
    Is this possible? If there are already resources available that answer my question, can you point me in the right direction?
    Thanks in advance,

    You has to use temporary CLOB for this purpose.
    If you needs some kind of examples I'll sent to you directly the codes.

  • Handling streaming attachments in Client Proxy

    I'm no java programmer in any shape or form so I'm really struggling with a web service that I've created that utilizes streaming attachments. THe OEM test web page returns the attachment perfectly well in the SOAP response but I'm unable to harness the Java to deal with it in the client proxy code.
    I created a proxy using the wsa command line utility but there is some java expertise required to code the 'main' class. Does anyone have an example of java code that takes the 'oracle.webservices.attachments' and returns it in a useful form to a calling application? In essence, what I'm looking to do is to call the proxy from pl/sql, and return the attachment as a CLOB.
    Does anyone know of any examples of proxy java code handling this type of thing?

    I've managed to create a proxy that saves the streaming attachment to a local directory (thanks to the info at this post: Re: Streaming Attachments
    The problem I have is that I have to hardcode parameters into the HttpSoap11Client code like this:
    public static void main(String[] args) {
    try {
    getxmlweb.proxy.HttpSoap11Client myPort = new getxmlweb.proxy.HttpSoap11Client();
    System.out.println("calling " + myPort.getEndpoint());
    // Add your own code here
    String pResId = null ;
    String pFileName= null;
    String pFilterStr = "sepa_region='North'";
    String fileName = "/tmp/plain1.txt";
    AttachmentFactory factory = AttachmentFactory.newInstance();
    Attachments atts = factory.createAttachments();
    myPort.getClob(pResId,pFileName,pFilterStr, atts);
    The last line here is the call to the method that creates the response, I need to pass parameters to this call DYNAMICALLY. I've tried setting up parameters in the 'public void main' signature but it doesn't compile telling me it must be public static void main(String[] args). This is where my lack of JAVA skills are letting me down.
    Can anyone see a way around this?

    You will need to create a WebDynpro Project for the DC ess/us/w4 and make the necessary changes & deploy it to the Portal.. assuming you have your NWDI & Dev Studio set up already.. evidently, you will need some Java expertise..

  • Technical requirements for SAP E-rectruiment

    Hello,
    We are using 4.7 version.
    We bought ECC 6.0 just a test server without portal facility  for practice. Now we require the portal access. Can anybody says that how we can get that from SAP, Our main purpose is to use E-recrutiment in Portal since we already have ECC 6.0. Now we would like to buy EP tool also, however we  need to give complete  technical requirements for E-recruitment tool implementations for approval.

    Hi Velu -
    E-Sourcing technical consultants will require SQL skills if you are developing custom reports. The E-Sourcing query and reporting tools utilize "annotated" SQL statements the result in a SQL query being executed against the relational database. It is also useful for the report developer to have skills specific to the DBMS being used (for example, Oracle skills) - often times, using DBMS specific SQL constructs can provide improved reporting.
    E-Sourcing has a feature called "scripting" that allows custom business logic to be included in the application and executed at various "call-out" points. The scripting feature provided by E-Sourcing uses a technology called BeanShell (see www.beanshell.org for more details on this technology). Beanshell development really requires strong programming skills using Java, although some components of BeanShell may be more like JavaScript. Regardless, I recommend Java expertise for writing E-Sourcing scripts. Knowledge of HTML is not required.
    The E-Sourcing workflow capabilities also utilize BeanShell, so if you plan to implement any workflows, you will also require such technical skills.
    Many other features of E-Sourcing such as user interface customization can be done with less technical individuals. Programming is not required.
    Hope this is helpful.

    Rob

  • Dynamic check box

    Hi I need help from all java expertise, I need to create dynamic check boxes. table have the customer name, one customer have multiple locations, on selection of customer name, all the locations should be displayed with chek box option, so that the user will allocate some rebate or ajustment to a particular location. How to achive this. any help will be appericiated
    thanks

    Lets assume that you got your customer information and everything is stored in a ResultSet rs
    The value of the radio buttons in this case will be the customer name but you can change it
    to whatever you want that way you can get the parameter accordingly to do your updates.
    <%
    ResultSet rs = ....... ;
    for( int n = 1; n <= rs.size(); n++ )
    while (rs.next()) {
    String custName = rs.getString("CUSTOMER_NAME");
    String custLoc = rs.getString("CUSTOMER_LOCATION");
    %>
    <tr>
    <td BGCOLOR="#FFFFCE" valign="top" align="left"><input type="radio" name="radioButton" value="<%=custName%>"> </td>

  • IView Explorer-Search

    Hi,  we are using EP6 SP15 and there is an iView that we used in EP5, called "com.sapportals.km.explorer-search" and it was very useful.  In EP6, this iView is now located in pcd:portal_content/com.sap.portal.migrated/ep_5.0/templates/com.sapportals.km.explorer-search.   But I got the following JAVA error : <i>System Error
    An exception occurred during the program execution. Below you will find technical information pertaining to this exception that you might want to forward to your system administrator.
    Exception Class = class java.lang.NullPointerException</i>
    Is there another iView in EP6 which does the same thing (as in EP5) or is someone knows what I need to do to correct this error.  (No JAVA expertise)
    thanks

    Hi,  this iView is built in 2 parts; the top one is a search component and the bottom is an explorer component.  So it allows you to have an iView pointing to a KM folder where you can configure a search capability only inside this folder (or also to the entire portal).
    As to create it,  I tried to use from the location SAP copied it,  then I copy-paste with delta and finally I created from PAR file.   In all cases,  I got the error message.  It looks like if the search capability is not working in this SAP iView.  
    It is very unfortunate because it is a very useful iView.

    Hello guyz, some reply pls...
    i personally feel that my problem should be improper replacement/version of library/class files which made the XML connection failed.
    Anyone can provide me web links or tutorial with the info of correct installation of (1)tomcat version, (2)necessary additional class file, (3)classpath setting, and (4)correct procedure to debug the JSP version 1.1 and Servlet version 2.3 running under WIN2K.
    I gonna try out this on a fresh machine coz Apache/SUN setting really very sensitive and this really giving me tough time to settle short timing project.
    Thanx first!
