Production Experience:
1. Use of JAVA DOC
If you want to learn English, do not think of a Chinese document for you. In this way, you are always following most people.

2. Use of online forums and search engines
Beginners are always fond of asking questions. I suggest you search for them online. You can find answers to most questions on the Internet, because they have asked similar questions.

3. Skills in common classes
If you really want to enter the line, you must be familiar with some common classes, do not go to the interview, for a common method and require to check java doc, leading to missed job opportunities. I had this experience a year ago.

4. Thoughts on creating common Website Functions
For example, how the article system implements image-text mixing. Let's take a look at the ideas for creating large websites.

5. SUN website tutorials and Examples
There are many good tutorials, including examples of using some methods of classes in JAVA class libraries.

Difficulties:
1. Chinese problems
If development is not performed on the English version of the operating system, it will not become a major event. Up to now, some problems have not been solved. For example, a DOS window is generated between TOMCAT started in the service under the control panel and after running. The two startup modes have different support for Chinese characters.

2. Bad website image problems
I do not know whether it is a problem with the network server or a problem with TOMCAT. There may be bad diagrams.


Finally:
Celebrate your first time using JSP/JAVABEAN technology to develop dynamic websites! For nearly two years, often patronize DEV-CLUB (CHINAASP), and CHINAJAVAWORLD, JAVAUNION, benefit from non-profit. Thank you!
