Re: Multiple Struts2 WAR in a single EAR
Thanks for your advices... Sure, the first configuration I tried was to put struts jars in each .war/WEB-INF/lib. For those interested, a good link on classloaders : https://glassfish.dev.java.net/nonav/javaee5/docs/DG/beade.html But it doesn't work with Glassfish in this configuration because of xwork as I've already pointed out : -- [#|2008-06-12T11:22:06.192+0200|SEVERE|sun-appserver9.1|javax.enterprise.system.container.web|_ThreadID=20;_ThreadName=httpWorkerThread-4848-0;_RequestID=48141413-1d12-4d21-918f-3950921f55ab;|WebModule[/ProjectB]PWC1270: Exception starting filter Struts2 Unable to load bean: type: class:com.opensymphony.xwork2.ObjectFactory - bean - jar:file:/Users/hugo/local/glassfish/domains/dev/applications/j2ee-apps/AgaVision/ProjectB_war/WEB-INF/lib/struts2-core-2.0.11.1.jar!/struts-default.xml:30:72 skipped stackTrace Caused by: Bean type class com.opensymphony.xwork2.ObjectFactory with the name xwork has already been loaded by bean - jar:file:/Users/hugo/local/glassfish/domains/dev/applications/j2ee-apps/AgaVision/ProjectA_war/WEB-INF/lib/struts2-core-2.0.11.1.jar!/struts-default.xml:30:72 - bean - jar:file:/Users/hugo/local/glassfish/domains/dev/applications/j2ee-apps/AgaVision/ProjectB_war/WEB-INF/lib/struts2-core-2.0.11.1.jar!/struts-default.xml:30:72 -- It seems there are problems like this as stated in this interesting forum entry : http://forums.java.net/jive/thread.jspa?messageID=260375 But I tried both class loader configuration in sun-web.xml descriptors with the same result (see stacktrace above). --- Default sun-web.xml : Modified sun-web.xml : This configuration use firstly the childs classloaders before to delegate. --- Tips : - I've searched for other remaining struts jars but have not found any. - I deploy directly from Eclipse, or export the ear from Eclipse and deploy it manually (Only 2 xwork references in the ear : 1 in each .war/WEB-INF/lib) I'm stuck with only one struts project by application for now...

Re: Multiple Struts2 WAR in a single EAR
In general it isn't a good idea to put those custom libs (like struts.jar, spring.jar) etc. in classloaders of the main appserver. They should be in the applications-classloader so you can avoid classloader-issues like leaks. If you've got the first error it sounds to me that you've got the xwork libs on ear level. If it's in web-inf/lib it shouldn't "see" each other. The classloaders _should_ be seperated. I'm not sure if glassfish handles it correctly but I would think so. May be you've got another xwork.jar somewhere else, which is loaded at first (such thing can happen if you build using maven and forgets to run a clean before final build.) If you've got two identically xwork.jars (or struts.jars) in the classpath or in parent classpaths they will be considered as two different types/versions. So I would think that you'll have a xwork.jar somewhere in your parent classpath. The second error occures if the loaded classes from lib/ext didn't find the dependent classes within the current and in one of the parent classloaders (up to the bootclassloader). If the javax.servlet.Filter is loaded by a seperate classloader (which might be a child of the classloader (which loads the classes from lib/ext) it wouldn't be found by the lib/ext classes.

What is the correct installation scheme for struts.jar with this configuration ? Thx...

Re: Multiple Struts2 WAR in a single EAR
In fact, this was my second question, so I ask it now :) I have had problems with deploying *struts*.jar in this special configuration (2 war in an ear). - I tries to put them in each .war WEB-INF/lib => "Error : xwork...ObjectFactory already loaded in bean projectA" at projectB deployment. - I tries to put them in glassfish domain lib/ext => "Error : ClassLoader : Can't find javax.servlet.Filter" So, they are for now in the glassfish "main" lib.. but there are problems too .. at runtime.

Re: Multiple Struts2 WAR in a single EAR
Hello, do you deploy the struts.jar in the ear or in the WEB-INF/lib folders of the war-files? if they're in the WEB-INF/lib folders they should be seperate.
