tomcat7

问题 How do I check the version of tomcat 7 that is installed on RHEL? I looked in the bin directory and cannot find version.sh. 回答1: You can publish a jsp with the following scriptlet: <%= application.getServerInfo() %> Or grep catalina.out for a line like: INFO: Starting Servlet Engine: Apache Tomcat/7.0.37 Or take a look at the file org/apache/catalina/util/ServerInfo.properties inside lib/catalina.jar . Just to give you 3 options ;). 回答2: Try this to see the names and versions of any Tomcat

问题 I'm running Tomcat 7 on Eclipse Indigo. Every now and then, Tomcat times out on start-up. A hit-and-miss solution I've found is to run Tomcat with the same server name and host name. I do this repeatedly and sometimes it works, sometimes it doesn't. I've also tried rotating HTTP ports between 8080, 9080, and 8081 but, as far as I'm concerned, this problem does not depend on the port. I'm also sure that the only Tomcat running is Eclipse's; I check my Task Manager. I'm wondering if anyone here

问题 I'm trying to have a simple Jersey based jaxrs listener, running on my existing tomcat 7.0.57. Tomcat has a global config in its context.xml for a jdbc datasource, which I want to use. My problem is that I can't get the resource to resolve via the @Resource annotation. Heres a simple test example @Path("/") public class TestJersey { @Resource(name = "jdbc/default") private DataSource dsA; @Resource(name = "java:comp/env/jdbc/default") private DataSource dsB; @Resource(lookup = "java:comp/env

问题 The default behaviour of tomcat sessions is to persist them on shutdown and restore them after startup. This works on my simple test application as expected. But when I add form based authentication the user login (User principal) won't get restored on tomcat restart. Even the example application located under /examples/jsp/security/protected/index.jsp does not restore the login. Is there any way to achieve session/authentication restoration without clustering/replication as suggested

问题 I will preface this with I am not using any maven dependencies, yet I know that I am missing a jar file wls-api.jar (at least that is what I have read). To remedy this I downloaded the oracle-weblogic-7.9.jar but the problem persists. The exception is thrown at this line WebSocketContainer container = ContainerProvider.getWebSocketContainer(); Can anyone tell me why this line continuously fails? UPDATE: upon further reading the examples I see use this dependency <dependency> <groupId>javax
