weblogic

I have created a MDB in java using JAXB to parse the xml content. This MDB is working from a long time now (about 3 years) on a 10.3.4 weblogic server. Now I've to migrate it on a weblogic 12.1.3 server, and for a reason I'm not knowing yet, the implemention choose by weblogic isn't the same as I want. But I can't figure out how to set it. Right now my code init code is this : private JAXBContext getJAXBContext() throws JAXBException { if (v1JaxbContext == null) { v1JaxbContext = JAXBContext.newInstance(MyClass.class); } System.out.println("jaxbContext : "+v1JaxbContext.getClass().getName());

When I try to throw an Array of strings to oracle stored procedure as: String arrStr[] ={"val1","val2","val3"}; ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor("STR_ARRAY", connection ); oracle.sql.ARRAY oracleArray = new oracle.sql.ARRAY(descriptor, connection, arrStr); oracleArray holds null data , oracleArray.datumArray = {???,???,???} In my case (see my comment above), it was caused by encoding problem, however - without any exception or debug information. Including orai18n.jar to the project libraries solved this... it is really sad, there is no exception or something that

最近看到经常有人提问weblogic相关问题，所以闲暇之际写几篇博文（基于weblogic11），仅供大家参考。 具体weblogic的介绍以及安装，这里就不赘述了。 以域的创建开篇，虽然简单，但是细节很多。步骤如下： 1、创建域（Domain）的方式： Domain简单定义为：是一个逻辑管理单元，Domain下面包含着weblogic应用服务器中的所有东西，weblogic应用服务器的启动，停止都是以domain为单位进行管理的 windows下面可以直接在开始菜单安装程序中创建domain，如图所示： linux下面可以直接进入weblogic安装目录中创建domain，具体位置： weblogic11/ wlserver_10.3/common/bin/config.sh 当然config.cmd即是windows的创建domain的方式了。 2、创建domain： 上图所示，默认选中“创建新的Weblogic域”，点击“下一步” “扩展现有的Weblogic域”是指对已经存在的域进行额外配置 3、选择域源： 上图所示，默认选中“Basic Weblogic Server Domain……”，即创建基本的域。点击“下一步” 其它几种domain类型是针对特定应用的，如sip、webservice。 4、指定域名和位置： 上图所示，输入域的名称“example”，域的位置默认是

I have a Java application that runs on Weblogic. The application needs to access a stored procedure in a DB2 data base, therefore a JDBC data source is configured and accessed by its JNDI name. Data source: ClassDriver: com.ibm.db2.jcc.DB2Driver Properties: user=MYUSER DatabaseName=MYDB The following example works as expected. Context env = null; DataSource pool = null; Hashtable ht = new Hashtable(); ht.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory"); ht.put(Context.PROVIDER_URL,"t3://myserver:7777"); env = new InitialContext(ht); pool = (DataSource) env.lookup(

How do I increase the memory used by my Weblogic (Java). While starting the server from eclipse it shows a message that JAVA Memory arguments: -Xms256m -Xmx512m -XX:MaxPermSize=256m . I couldn't understand from where is it taking that value from. After sometime the Weblogic server fails because of low permgen space. I added startup arguments from console but that doesn't have any effect. Can you help me from where is it taking the memory values from? When you configure a "Server" in Eclipse for WebLogic, you select a domain directory (for local). That domain directory contains the startup

I have a .war file for an application that normally runs fine in Jetty. I'm trying to port the application to run in WebLogic, but at startup I'm getting these exceptions: ERROR:Foo - Error in named query: findBar org.hibernate.QueryException: ClassNotFoundException: org.hibernate.hql.ast.HqlToken [from Bar] at org.hibernate.hql.ast.HqlLexer.panic(HqlLexer.java:80) at antlr.CharScanner.setTokenObjectClass(CharScanner.java:340) at org.hibernate.hql.ast.HqlLexer.setTokenObjectClass(HqlLexer.java:54) at antlr.CharScanner.<init>(CharScanner.java:51) at antlr.CharScanner.<init>(CharScanner.java:60)

We have many Spring web applications to make on a WebLogic server and are curious about when WARs should go in an EAR and when they should just exist as WARs. Occassionally, the WARs will need to access common logic JARs, but I don't see why these would need to go into an EAR when they could just be packaged into the WARs. From what I understand, if several WARs are in an EAR and you need to modify one of those WARs, you need to redeploy the entire EAR to update the server. This will cause all of the WARs to bounce. If they weren't in an EAR, however, I could just update the one WAR and it
