The next Java step

Hi, I am at the level of Java programmer and I really do want to go as far into Java technology as it would take me. What I am having trouble with now is identifying the next step. If anyoun can tell me what steps they took after becoming a Java certified programmer.
I got the O'Reilly book Java and XML by McLaughlin and it seem to be pretty good on explaining web services. I am not sure whether I should focuss on web services rather than doing the Java Developer certification.
Any help would be appreciated.

There are pros and cons with going to get the certifications first.
On the one hand, it forces you to learn all about Java. On the other, you have no practical experience (I just decided to hire someone with experience versus a guy who had all the certs, but no experience.)
I went along the "get as much experience as possible first" route. Even in this ecomony, when I got laid off, I was hired somewhere else within a week.
Just my opinion - and you know what opinions are worth. ;)

  • How to terminate the next job step in Background job?

    Hi,
    I have the requirement from the user that want to terminate the next job step in the background job that currently running (Status Active).
    For example, Background Job A, contains 5 job step, once the background is running, we would like Job A not run thru job step 4 and 5, just run up to job step 3. 
    Anyone have any idea how can I do that?
    Thanks
    Nattawat S.

    Hi,
              Try to delete instead of cancel in SM37.
    To cancel and active job, select the job from SM37 and Click on STOP button in application toolbar. You can refer to your other thread for more info.

  • GP-The next process step still continue when current step has terminated

    Hi,
    I'm using CE7.1 SP3.  I have created a business process flow using the Guided Procedure.  Each step in the process is done by different role.
    I have an approval step in the process.  When the user clicks approve, the next step will get executed.  When the user clicks reject, the whole process should be terminated.  However during testing, it is found that the next step can still be executed even though a rejection is specified.  The process is not ended.
    I have specified in GP that if reject is selected, it should go to terminal state.
    Can anyone help?
    Thanks.

    Hi James, Hi Maarten,
    I also tested this step property in TestStand 2.0.1. and as result of my tests I can say the followings:
    - If you set the CancelCurrentExecution property from a defined PreSubstep for a step type, than the step is not further executed (e.g. behaves normal)
    - If you set the CancelCurrentExecution property from any other place (e.g. engine callbacks, sequencefile callbacks, post substep aso), then the step is executed normally (e.g. behaves abnormal)
    The attached sequence file contains a modified MessagePopup step which has an additional PreSubstep that will set the Step.CancelCurrentExecution to the value of the Step.CancelExecution step sub-property.
    When this sub-property is set to TRUE then
    the message window is not shown anymore.
    James, you're right, and Maarten, if you need this functionality for a limited set of steps then you can use this feature as a PreSubstep too.

  • Cloud App Action Service - how let contacts continue through to the next step?

    I have created an eloqua cloud app with an action service.
    To test it, I am creating a multi-step campaign which is really simple:
    A segment with a couple of members flows into my action cloud service, which then flows into something else like an email or something.
    However, I am having trouble getting the contacts to flow through the cloud service action step: they all seem to be stuck there and are not continuing.
    According to both the Bulk 2.0 api documentation and the sites on making an action service (Develop an AppCloud Action Service),
    when contacts flow into the action service step, eloqua will request out to my notification url (I am getting this successfully),
    after that, I am to respond with some status code, and the example is a 204 status code followed by an asynchronous bulk data import/export.
    My action doesn't require any import or export, and my goal is to either do my work and respond back that I am finished, or if it will take some time: respond back to have eloqua wait, then send a request later that I am finished.
    After this, the contacts can flow on to the next step in the campaign canvas.
    So, I realize that after I get the notification I can respond with a 204 status to let eloqua know that I will use the bulk api's async calls to import/export data.
    But what other statuses can I use if I don't want to or don't need to use the async api calls?
    Can I just return a 200 status if I am done and want eloqua to proceed to the next campaign step?
    Can I return some status to make eloqua wait for me to do some processing on my side, followed by some status to let eloqua proceed?
    I have tried several different 200 level statuses and none of them seem to let my contacts move on to the next step.
    Please help.
    thanks,
    Chris

    No you will need to update their status using an Import. You can not just use your Response.
    What you are talking about requires you to respond back by performing a BULK Import action of "SetStatus" with a status of "Complete"

    I am actually doing this for the first time myself just this moment. Its not hard but I am struggling with the ML to provide it a Destination that is likes.

  • Apple loop index is empty folder!!! Can not find loop in logic browser because they just no longer exist on my hard drive, what would be the new appropriate step to take?

    Apple loop index folder is empty from the hard drive, which may explain why i can not find loop in my logic pro browser, just sort of grey in disaabled format. what would be the next appropriate steps to take??? I do have an external back up disk.

    The IDE interface that the iBook and your desktop use are the same, just a different plug size. So with the rite adapter you could put the iBooks drive in your desktop, you could even boot off it too.
    If you want to install the laptops HD in your desktop this will do it for you. Or you can use the iBooks HD as an external hard drive with this

  • The 'Third Party Connections' drop down box on the 'Source Database' step in the Migration Wizard is empty.

    Here are the environmental details:  
    SQLDeveloper 32-bit Version 3.2.20.09 (Build MAIN-09.87)
    Oracle Database:  12C single instance (no RAC)
    Oracle client:  12C 32 bit
    Windows 64 bit desktop
    I am attempting to migrate an MS Access application to Oracle.  I pick the ‘Migrate’ selection from the ‘Tools’ Menu SQL Developer.  This puts me into the Migration Wizard.  When I get to the ‘Source Database’ step of the migration wizard, the ‘Choose the Third Party database from which you are migrating’  drop-down box is not being populated with the current available connections. It is empty.  If I type a valid connection name into the box, SQL Developer takes it on this screen but does not keep it for the next screen/step.  It has no persistence.  I even tried to make sure that each connection was open/connected before beginning the migration process.
    Due to the fact that I am attempting to migrate an MSAccess application, I am mixing 32-bit and 64 bit software.  This may be the issue as to why the drop down is losing addressability.  I have not applied any patches to this version of SQL Developer.

    Hi,
    If you need easy way to migrate Microsoft Access to Oracle probably it is more reasonable to review some tools specially designed to this purpose. For example:
    Access to Oracle converter by Intelligent Converters
    Access to Oracle converter by SpectralCore
    Access to Oracle converter by Interface Computers
    Hope, this will help.
    Sincerely,

  • I've learned the basics, what's the next step?

    Hi guys! I've just finished a book (Java - A Beginner's Guide) and some of the tutorials on sun.com and I'm wondering what's the next step?
    The reason I'm learning Java is to get a programming job somewhere in the future. I'm in the medical field and I want to change careers. I always loved computers and technology!
    I've browsed the job market in our country and a lot of them are looking for J2EE capable people. How do I make the transition to J2EE? Is there a good book available for learning it? How should I prepare next?
    Thanks!

    Sounds to me that you want to learn J2EE to get a job in Java. The problem with J2EE is that knowing it alone wont get you a job doing it. Also, programming J2EE requires that you know J2SE, so make sure you are extremely comfortable with J2SE before moving on.I agree. You should focus on understanding the compiler, runtime, and core API well before moving on. You should write several applications (even a couple advanced level apps) before moving out of core. But you don't need to do a lot with stuff like Swing or whatever. I would touch JDBC and I'd also get some understanding of threads.
    If you want to code J2EE you typically have to specialize on something. There are many roles in a J2EE project; for example, do you want to do presentation logic using JSP, code EJBs in the business layer, or administer and deploy J2EE applications? In addition, employers typically use a particular application server (i.e. Websphere, Weblogic, JBoss, Geronimo) so you will have to get familiar with them.I disagree for the most part. For the past 7 years of doing J2EE contracts (probably a dozen projects or so) it's rare that the roles are divided. Occasionally you have a web developer that will do the graphics and layout and design of web pages, but the Java/J2EE developer usually does everything else. It's not uncommon to have someone who primarily does server configurations and deployments, but you will need to learn that soon enough. Most of the time that responsibility is shared.
    I would recommend reading Mastering EJB. You can download a free copy at http://www.theserverside.com/tt/books/wiley/masteringEJB. You should be able to use it as a guide to develop some test applications on a free application server such as JBoss, Geronimo, Glassfish, or WebSphere Community Edition.
    I haven't worked on EJB's since 2003. Nobody seems to use them. Some people are getting back into it now that it's EJB3 but nobody I know. Save EJB for last. Focus on JSP/Servlets, XML, JNDI, Web Services, maybe JMS...

  • I am trying to restore a phone on iTunes, but the setup page doesn't go on to the next step. What do I do?

    My iPhone 4S was stolen, so until I could get or buy another, I am using my husband's old 3GS.  When I connect to iTunes, the left column recognizes the phone. Then I see the Setup page.  It asks whether you have a new phone to add, or restore from a previous backup of my original 4S.  I click restore from back up and click continue.  It restores the 3GS, but the page doesnt move on to the next step.  I have restored multiple times.  The page/screen stays the same.  What should I do? Am I doing something wrong?

    You could follow the instructions in the support document that you linked from. There is a section regarding the passcode and the inability to use it or enter it. However, you may encounter more issues since you cannot use the screen.

  • What is the next step after editing or triming a video ? What type of file format to save and what to do after that ?

    what is the next step after editing or triming a video?
    what type of file format should be save and what to do after that?

    In the early days of digital video editing, an export render could take hours!  Not many applications are as hard on system resources as video editing, and rendering the final edit is probably the most system intense action of all.  
    Head on over to the Premiere Pro Hardware forum to see what sort of computer hardware the pros use for NLE (non linear editing), or to the PPBM5 site for a better look.

    It sounds to me like you either got defective parts or otherwise did not make the repair correctly. We cannot help  with self-repairs here, the iPhone officially not user servicable, but you can ask for advice in the forums on ifixit.com, a site which is dedicated to those attempting their own repairs.

  • Java options: "Enable the next-generation Java Plug-in"

    On windows, this option is sometimes "grayed out" and you cannot disable it.
    This option is available since java 6 u 10, and is accessible via windows control panel, or alternatively via javacpl.exe.
    Which are the cases where the option is grayed out?
    I've made the assumption that it is grayed out on windows 7, or on windows 7 64, but there are cases of windows 7 64 where the option isn't grayed out.
    It seem neither connected with Internet Explorer version, since it works or not with either IE 8 or IE 9.

  • Does Firefox support java applets if the "Next generation plugin" is disabled via the Java plugin control panel.

    I'm still trying to get a definitive answer to this question.
    My applet is not "Next Generation compliant". When we run our applet in Internet Explorer it runs fine as long as we disable the "Next Generation Plugin" via the Java plugin control panel. However our applet does not run in Firefox if the "next generation applet" is disabled.
    Is it a requirement that if I want to run an applet in Firefox 3.6.x or higher that the "next generation plugin" be enabled via the Java plugin control panel.

    Current Firefox versions (3.6 and later) can only run Java applets via the Next Generation plugin.
