问题 Is there a full documentaion of the deployment descriptor that describes each element and each sub-element? I realy can't find it. P.S. I ask because I found the way to set maxAge of session cookies by adding <session-config> <session-timeout>525600</session-timeout> <cookie-config> <max-age>31536000</max-age> </cookie-config> </session-config> into DD. But I cannot find any official documentation that describes <cookie-config> element. 回答1: For the standard Java EE deployment descriptor

Question is: Is this a known bug?

I have a simple ear with only one jar that contains an EJB, and to that ear META-INF folder I have added a jboss-app.xml with the following content: <?xml version="1.0" encoding="UTF-8"?> <jboss-app> <security

问题 I had a web filter to redirect from the login and index page if the user was already authenticated. Originally I had an invalid URL pattern. I fixed the invalid pattern and attempted to redeploy only to receive this: java.lang.IllegalArgumentException: Invalid URL Pattern: [{0}] at org.glassfish.web.deployment.node.WebResourceCollectionNode.setElementValue(WebResourceCollectionNode.java:136) I checked around in my application to see if I was missing something or had typed something else wrong
