问题 Hi I'm using Struts 1.2 and I installed TinyMCE. The problem is that struts is converting all HTML tags into entities. How do I disable or configure this to allow only selected tags? 回答1: Use the filter parameter (taglib). <bean:write name="someField" filter="false"/> 回答2: Thanks, I was looking for this but in Struts 2, and this helped, it's similar: <s:property value="variable" escape="false" /> 来源： https://stackoverflow.com/questions/716922/disable-struts-converting-html-tags-into-entities

问题 Package structure should be same as directory structure in Java it seems in Eclipse. I tried to browse through the formal documentation on Oracle Java docs but nowhere I could find this rule Does this rule extend to other IDEs such as Netbeans or is this a rule of Java language itself? How strict is this rule, can it be deviated from and why was it made? 回答1: It's specified in the JLS as a rule that compilers may require: Packages that are stored in a file system may have certain constraints

问题 Is there any way to get access to the ServletContext from a method without passing the ServletContext as an argument? I need to have a generic Configuration class that can work on several environments and load the config in a way depending on the environment. For example, when in a web app, i need to get the configuration from either web.xml or a config file stored in WEB-INF. But in order to know if the app is running in a web app i need to gain access to the ServletContext somehow. Any

问题 I need to set some context before every database operation (I have tried using Oracle's package-level variables, but due to some issues with package recompilation, I will experiment with DBMS_SESSION and/or DBMS_APPLICATION_INFO), so that we can get specific user info anywhere we need it (procedures, triggers, etc.), instead of having dozens of database connections identified as "JBoss". I have written a Java EE interceptor that intercepts calls to a @Stateless bean. It calls an Oracle

问题 is there a way to lookup an EJB in weblogic if it implements only local interface? If I use this @Remote public interface TestSessionRemote { public void businessMethod(); } @Stateless(mappedName = "A") public class TestSessionBean implements TestSessionRemote { public void businessMethod() { } } the EJB can be looked up using this name: "A#" + TestSessionRemote.class.getName() If I change the annotation for TestSessionRemote from @Remote to @Local the EJB disappears from JNDI. Is there a way
