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...

What are the basic difference in the putting a variable in Query

what are the basic difference in the putting a variable in
1. Characteristic Restrictions Vs 2. Default Values

Example - Cost Center Analysis Report - If I have Controlling Area in
Char Restricitons Only - I have restricted it to say ABC Controlling Area or a Variable- Report will be hardcoded to ABC Controlling Area or the Input Value entered during Runtime - After Execution, The Same cannot be changed in the report.
Assuming I will not have Controlling Area in the report means not in Rows n Columns.
You might have seen no change - > Did you place material in Rows or Columns ?

Using iPhone/iPad Recovery Mode

Saw this solution on another post about an iPad in a school enviroment. Might work on your iPad so you won't lose everything.

‘iPad is disabled’ fix without resetting using iTunes
Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
2. Open iTunes with the iPad disconnected.
3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
5. Click ‘Setup as new iPad’ and then click restore.
6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
8. The first stage in the restore process unlocks the iPad, you are basically just cancelling out the restore process as soon as it reactivates the iPad.
If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.

Try it and good luck. You have nothing more to lose if it doesn't work for you.

I was processing pictures and the Basic function on the right has disappeared, the one that contains Exposure, Contrast etc. I now have only the Histogram, Paint Brush etc, then it goes to Tone Curve, HSL/Color/B&W and all others down to Camera Calibration. How can I recuperate Basic ?? Thanks for your help

i have now found where the OS permission is located but cannot find a way to change it. Here is what I have done:
- Selected the Local Disk Folder
- Chose File>Get Info
- Click on Sharing and Permissions (It shows Read Only)
Now this is where I am stuck, the instruction in Apple Support says "Select a user or Group from the Name Column then choose the following Pop-Up menu in the Priviliges column(this is where the Read &Write option should be. I can't choose a user or group under the name column, all I have in the Name column is "Local Disk"
Can someone help me from here to convert to Read & Write, thanks

If you are the only user on your computer you probably don't have multiple user accounts set up and can disregard that. If you are using iTunes 11 go to View>Show Sidebar. Now see if your iPad appears under Devices on the left side when you connect it. If it does, click on the name of your iPad on the left side and your iTunes sync settings options will appear in folders with tabbed headings to the right.
If it doesn't appear on the left side, follow the troubleshooting steps shown in this article: http://support.apple.com/kb/TS1538.

I was trying to do a favor for my gf, and I uninstalled bonjour. What are my next steps with the cloud and ios5

I was trying to do a favor for my gf, and I accidentily on purpose uninstalled bonjour. It has seemed to really screw up iTunes for me. What are my next steps to get this back to normal? I have downloaded and using the icloud and ios5. I have two iPhones 3gs and our iPad2. And our computer is windows xp(yes it is time for an upgrade)

Try the troubleshooting help here. http://www.apple.com/support/iphone/assistant/phone/
You may need to restore your iPhone.
If it won't restore, try here. http://support.apple.com/kb/ht1808
If nothing helps, you need to contact Verizon for information for an exchange or refund. This is a user to user forum, not Apple.
Apple's policy for a refund or exchange is within 14 days of purchase. Verizon's policy may be different.
Definitely try restoring .. hopefully you won't have to go through the hassle of an exchange.

What does "it will not let me purchase it" mean exactly? Are you getting an error message?

Since the 12/9/14 update of Adobe Acrobat XI Standard to 11.0.10 I have lost the basic colors of the highlighting tool. How do I fix this?

Adobe Acrobat XI Standard to 11.0.10 I have lost the basic colors of the highlighting tool. How do I fix this?

Hi,
It appears that this was a bug that was introduced in the latest update. Others have been able to resolve this issue by using the Acrobat Cleaner tool to uninstall and then reinstall Acrobat. You might try this if you have a few spare moments.
And can you please share the problem PDF which was working correctly in the earlier version.
Thank you

If you use extensions like Adblock Plus or NoScript or Flashblock that can block content then make sure that such extensions aren't blocking content. 
You can see the installed Firefox extensions in "Tools > Add-ons > Extensions".
Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

My ipad says it is loading info but never connecs to the site, what is the likely problem?

My Ipad says it is loading but never connects to the site, what is the likely problem.?

Loading what? Applications? iOS?
If you're trying to load many simultaneous applications, and they all say "waiting", try clicking all of them which will put them into the "paused" state. Then click one at a time, let that one finish installing, then click the next.

Depends on what model it is...?
The Storage temperature spec's for the late 2009, 2010 and 2011 models was -4° to 116° F (-20° to 47° C), but that might not be true for the newer models with a sealed monitor.
see > iMac (21.5-inch, Mid 2011) - Technical Specifications
The Storage tempterature for the early 2009 and older models was -40° to 185° F (-40° to 85° C)

You have to change the photo to Process Version 2012.
Under the histogram in the develop module is a Lightning Bolt icon. Click on it.

I have tried the above fix and iTunes crashes giving error 27 after trying to load the iPhone firmware.
I have booted my phone in DFU mode and this has made no difference.
My mac is up to date.
My iTunes is up to date.
All i tried to do was update my ios as i have been unable to make calls or send text's all day.
Do you have any other suggestions as my phone is no good to me now.
Many thanks,
