Why do you want to configure Tomcat as the in-process part of Apache? 1. Tomcat processing static page without Apache fast 2. Tomcat is easier to configure than Apache 3. Tomcat does not have Apache stability and robustness 4. Apache supports CGI scripts and api,perl,php, etc. Now let me try to configure 1. Review me Apache and Tomcat installation first My machine is the Chinese version of Windows jdk1.3 and has been installed in the d:jdk1.3 Apache I install in D:program filesapache Groupapache

and discard broadcast traffic that exceeds the set value. Abundant Gigabit scalability To meet the needs of more users, the Alpha Gigabit Switch series not only provides 24 fixed 10/100/1000TX ports, but also has 2 SPF fiber expansion slots (optional ), with rich Gigabit scalability, all SPF modules support hot swapping, making the construction of Internet cafes, small and medium-sized enterprises and

Metering Standard. RIP is widely used in the routing selection of global interconnection networks. It is an internal gateway protocol provided by the UNIX Berkeley standard distribution system. Ip rip is defined in RFC 1058 and RFC 1723. RIP2-is the latest enhanced version of RIP. It allows RIP packets to contain more information and provides a simple authentication mechanism. It is described in RFC 1723. Open Shortest Path First version 2nd (OSPFv2)-it is the second version of OSPF. OSPF is a

topology. Calculate the shortest path to each network by using the drawn topology and shortest path priority algorithm. Advantages of OSPF route selection Protocol: fast convergence speed; service type selection; load balancing and identity authentication. Disadvantages: High router processing capability and bandwidth requirements. Applicable environment: large-scale and complex environments the principles of the Internet are different: Vector-distance routing selection algorithm: No need for a

OSPF is the link state protocol, mainly interface status (such as IP address, mask, hello time ...). During the process of establishing adjency between routers, the routers will be exchanged through LSAs until the same area converges. All routers have the same link state database, and then create an SPF tree based on their own root, finally, the route table is calculated based on SPF. any interface changes

uses relative paths to read XML files:I. xml files are generally stored in three locations:1. Put it under the WEB-INF;2. Put the XML file in the/WEB-INF/classes directory or the jar package of classpath;3. Put it in the same package as the Java class to parse it, not necessarily classpath;2. Two corresponding reading methods using relative paths:Method 1: (not verified)Put the XML file under the WEB-INF directory, and thenProgram code:Inputstream is = getservletcontext (). getresourceasstream

OSPF (Open Shortest Path First) is affiliated with IGP (Internal Gateway Protocol)Used for decision routing in a single autonomous system. It is an implementation of the link status routing protocol. OSPF is an open version of SPF routing protocol. Use algorithm: Dijkstra (decomposition video: http://v.youku.com/v_show/id_XMjQyOTY1NDQw.html) Note that OSPF is used in the same routing domain, or an autonomous system. All intra-domain routes maintain

When the Aspell program is used primarily by other programs that require spell-checking capabilities, it can be very effective on the command line as a standalone tool.Q: 7 How do I view the domain
