Install the JDK to the computer! Follow the prompts to the next step can be successfully installed. 4. Extract Resin compression package to just install the Java

. Otherwise, there may be some inexplicable problems.(3) MySQL driver jar package also does not need to be added, because the jar package is also already available in the JBPM project. It is recommended to use the MySQL driver jar package provided in the JBPM project. Native is more reliable, but pro-test using the MySQL official website provided by the drive Jar package is also no problem.(4) Add spring related jar package.　　　　　　(6) Add the relevant jar package for STRUTS2.　　　　　　(

field is null, then the hashcode value is 0.(7) In the case of arrays, each element needs to be treated as a separate domain. The Java.util.Arrays.hashCode method contains 8 basic types of arrays and hashcode computations of reference arrays, as in the previous algorithm.C, finally, the hash code of each domain is merged into the object's hashing code.This is illustrated by an example below. In this example, the person class overrides the Equals () m

same time, it obtains the request form from the HttpServletRequest and calls the corresponding doget (), DoPost (), DoPut () and so on.Take DoPost () as an example, the implementation is as follows; As you can see, the access level is protected and the default implementation is to return the error directly, so this is a method that is open to subclasses to inherit and implement.If the subclass does not implement the corresponding method, the request results are as shown.Conversely, to implement
