jBpm3.0 out for 10 days, really just two days before the use of free time, simply turned over the document introduction, but there is no time to go over the source code. The 3.0 model definition has been changed a little, but it has expanded a lot: super-state, expanded the definition of event, added timer and Exception-handler. One of the biggest extensions, of course, is the GPD (jbpm graphical process definition) based on the Eclipse plug-in, unlik

I. Review of the first day's core content 1, JBPM is what. What to bring to my project. Workflow is to automate the business process, not manually, control the execution of the task--------all business Process execution information can be stored in the database JBPM is currently very popular an open source workflow framework When project business processes are numerous and complex, using workflows to manage projects and reduce business operations errors, all business references 2, JBPM Workflo

own (see the attachment test. c) to display lines of any color on the display screen.Problem AnalysisDuring the LCD Driver porting process, problems mainly occur due to incorrect register settings.After replacing the driver with functions and rewriting some functions, compile the driver into the kernel. The kernel can correctly compile the connection and generate an image file, download the image file to the development board. You can see a device file registered by the system under the drivers

Defining gpio ports mainly involves the following macros: # Define make_gpio_num (p, O) (P The value of gpio_ofs_shift is 0, which indicates the displacement of the Offset number in the gpio group i

in damage to the device. Therefore, it is not recommended that local grounding be used as a reliable path for current backflow (see Figure 8a ). We do not recommend that you directly use a ground wire to connect to a remote location (see Figure 8b) because this may lead to a large amount of local loop current, coupled to the data line to become a common mode noise. As recommended by the RS-485, the circuit current is reduced by inserting resistance on the grounding path by only half of the prob

Jbpm Learning (1) ---- Environment Building My first contact with jbpm is something I have summarized below. I hope it will be useful to you. Some of the content can be found on the Internet.1. Build the environment 1. download the jboss-4.0.3sp1.zip and jbpm-starters-kit-3.1.4.zip files from the official website of jboss, decompress the two files respectively. After decompression, we get two folders: jboss-4.0.3SP1 and jbpm-starters-kit-3.1.4. Here, I will store these two folders in the root di

I. Definition of General I/O Gpio (general-purpose Io ports), a general IO port. Generally, micro-control chips provide universal programmable interfaces. Based on their functions: ● General Io control registers● Io data register Many of the gpio interfaces of MCU go out of the standard registers and provide up-pull registers. You can set the output mode of Io to high impedance. II. General Io registers of S3C2410A S3C2410A has a total of 117 reusable input/output ports, respectively port ~ H, a

The custom file of the Unidrv micro driver is a. gpd file, and the. ppd file is a PostScript micro driver. Windows Server 2003 comes with drivers for 3,800 printing devices. Although these drivers are provided by Microsoft to Windows Server 2003, most of them are provided

Overview: In recent years, due to the upgrade of China's consumption industry, the consumption level and consumption capacity of Chinese people have been increasing. Among the three driving drivers of investment, consumption, and export, the demand for consumption has been increasing and the demand for consumption has been increasing, this will boost GPD in China in the future. As consumption in China grows, new things like coupon printers emerge.

Because the graphical process designer (GPD) functionality provided by JBPM is not particularly comprehensive, many designs cannot be completed entirely in the graphical interface. So, in many cases, we need to directly edit JPDL's XML source code, so,It is a good idea to specify schema for JPDL XML. Benefits:1. Quick call out syntax hints via shortcut key "alt+/" in Eclipse2.Schema Association can help verify syntax errors for JPDLThe process of conf

First, Introduction (a) What is jbpm　　　　JBPM, the full name is the Java business process Management(Orchestration Management), which covers business process management, workflow , An open-source, flexible, and extensible executable process language framework in the areas of service collaboration. (ii) Why use jbpm　　　　Business analysts and developers use the same language to talk, greatly reducing the risk of development, if you want to develop a project, the speed is also faster, because devel

To enable MP3 playback, we recently completed the I2S driver on sep4020. The main experience is summarized as follows: 1. First, perform a series of initialization in the probe function.Is very important, and many ● Configure the gpio port Line for operating codec l3; Compared with a mixer control interface, the L3 interface corresponds to the mixer structure in the driver. here we need to use three gpio port lines to control the L3. The following is the initialization code: * (Volatile unsigne
