Although JRuby's performance is close to Cruby, sometimes it's still not fast enough. Cruby users can use Ryan Davis's Rubyinline Library, which provides built-in support for C + + to make it easier to generate Ruby's C extensions. Charles Nutter from the JRuby camp has now implemented a Rubyinline builder for JRuby, which can instantly compile embedded Java code

letters to be generated. If the sequence ZZ is required to be generated, the upper bound is 2.
3. A method that combines letters in the alphabet with previously generated letters into a cartesian product.
Let's take a look at the Code:
1. generate an alphabet
We can write the alphabet like this, for example:
1
List"A", "B", ..., "Z");
But this is poor. We use jOO λ instead:

Not long ago, I made a small project to generate PDF reports through JSP, opening my eyes. Some enterprise information forms Html reports through the network. Although IE can directly print the content displayed in the reports, from the perspective of the interface, if the Html display result is printed directly, not very nice. If you convert it into a PDF file and then print it, the printing effect will be much better.

simplicity, let's take the defined method as an example to see how to automatically generate the Web Service Server Based on the WSDL file.
We have a new Web service, such:
Remember to select "Top down Java Bean Web Service" in Web service type, for example:
Then, find the manager. WSDL file you just wrote in service definition.
Return to the Web Service dialog box and adjust the service type
The main is to: 1. Assemble your own model name to generate the code with a number2. Dynamically get path according to model name3. Generate code according to model judgment, only generate the code of the current model object
