　　AbstractThis article studies how to use the original heterogeneous database to establish a Department Management System in the campus network environment, and introduces the design and implementation process of the comprehensive management system for teaching materials based on WebLogic application server. 　　KeywordsDatabase; J2EE; EJB; WebLogic　　Introduction With the continuous improvement of science and

Feedback from the implementer yesterday: After Weblogic is started, you cannot enter the console. IE displays a blank page and does not even have a logon interface! I personally remotely log on to the server to access the server. In this case, all the Weblogic-related files are displayed. It is depressing that the problem of no error is the most difficult to solve. The service cannot be restarted because th

Because operating systems, browsers, databases, and JVM use different character sets, applications developed based on WebLogic Server often encounter Chinese display garbled characters, in fact, the Web applications running on WebLogic Server have many settings related to character sets. The following is a summary. In order to correctly process Chinese characters, it is best to set these settings. 1. Add t

Recently, the company's Sichuan Division project had frequent alarms for two consecutive days, and the time points were just a few minutes later than. The too Division file open log is as follows:(Too program open files) At java. Io. fileinputstream. Open (native method) At java. Io. fileinputstream. At weblogic. utils. classloaders. filesource. getinputstream (filesource. Java: 31) At weblogic. servlet. In

Docker is a popular technical topic at present, WebLogic Server supports Docker from version 12.1.3, but for operating system and kernel requirements, the following tableI tried on ubuntu,oracle Enterprise Linux 6 UL7 and failed to install Docker, so you need to pay close attention to the version.The Weblogic Docker image is divided into three layers, the underlying image is primarily for the operating syst

In the integration of Web server and application server, the integration of Apache and WebLogic is the most common and the most basic integration is configured today: Apache 2.0weblogic 8.11. Copy mod_wl_22.so from WebLogic to Apache Modules Directory (* Note: weblogic8.1 is not for apache2.2 version of mod_wl_22.so, only for apache2.0 version of Mod_wl_20.so, Need to be from somewhere else such as down one

RangeApplies to the Weblogic server used. This specification proposes a Weblogic server security configurationrequirements, applicable to all safety levels, can be used as the preparation of equipment network testing, safety acceptance, security inspection norms, etc.A reference to the document.Due to different versions, configuration operation differs, this specification takes weblogic9.x on UNIX platform

This article describes the various JDBC-related features in the BEA WebLogic 8.1 server configuration. Although we use Oracle 8.1.7 as our sample database management system (DBMS), it is easy to transfer generic concepts to these databases as long as other relational databases provide connectivity through JDBC. JDBC is a standard Java API, and almost all of the EE applications that need access to the database use it directly or indirectly. In Bea

These days to do transaction recover test, found a difficult to understand the problem. The specific problem scenario is as follows: 1: A standby client program that calls Usertransaction.begin () and then operates in sequence two XA resource, two resource for the same Oracle database, However, the operation uses connection from different data source. Connection1 inserts a piece of data into the table test, Connection2 inserts a piece of data into the table test1. The final execution of Usertr

At the company's request, recently in the learning WebLogic cluster this piece of knowledge, I have learned these days, and the process encountered problems and how to solve, share to everyone. First of all, WebLogic is a product of Orcale company, as for its role, I think I don't have to say. But I think it is necessary to say a few words about the professional nouns in

Today encountered a wonderful problem, project switching environment, resulting in the foreground query time format programming a string of numbers. The above illustration shows (the old Environment), (the new environment), the system is ported as is. This problem plagued for a long time, online search methods, but not fruit. Analysis of the problem: The project is a transplant, so it is not a project problem, certainly environmental issues. Environmental analysis: 1, the old system: weblogic9.2

A project that was developed using Jbuilder+weblogic (named Tsterp) was not familiar with the WebLogic and JBuilder, and the working principles of both were not well understood, Only know that the application of WebLogic can be developed very conveniently under JBuilder, until later, when I want to migrate the project to Tomcat, I find it always 404. At that time

The first step is to make it clear that to get a weblogic connection you have to rely on the weblogic associated jar, Not weblogic.jar on the Internet, if you put Weblogic.jar in your classpath is not enough, because the Java class file can not find errors such as [caused by: Weblogic.security.subject.AbstractSubject Java.lang.noclassdeffounderror:weblogic/security/subject/abstractsubject] exception. So wha

Create a Tomcat/Weblogic cluster using Docker Install Tomcat Image Prepare required software such as jdk and tomcat in the home directory and start a container.Docker run-t-I-v/home:/opt/data -- name mk_tomcat Ubuntu/bin/bash This command mounts the local home directory to the/opt/data directory of the container. If the directory in the container does not exist, it is automatically created. The next step is the basic configuration of tomcat. After the

Article Title:: Summary of installing Weblogic in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Installing weblogic in Linux is quite simple. There are two major steps in total: 1. Install the weblogic main program 2.

Note: Part 1: how to configure the Microsoft sqlserverdriver 2000 driver in weblogic7.0 without using the built-in sqlserver2000. I used RS in the program. before () appears: Java. SQL. sqlexception: This JDBC 2.0 method is not implemented, so the MS driver is used. But I don't know why the MS driver occupies a lot of database connections on weblogic7.0. Part 2: sybase1x and sqlserver2000 use the configuration parameters of the Weblogic built-in drive

EJB knowledge frequently used in interviewsWhat is the difference between EJB and Java Bean?A: Java Bean is a reusable component and there is no strict specification for Java Bean. Theoretically, any Java class can be a bean. However, since Java Beans are created by containers (such as Tomcat), Java Beans should have a constructor without parameters. In addition, generally, Java Bean must implement the serializable interface to realize bean persistence. Java Beans cannot be accessed across proce
