Re: Deploying Struts 2 Portlet Into Pluto 1.1.6 Portlet Container
Well - after hours of trouble-shooting I finally figured out what my problem was. The error was in my web.xml: servlet servlet-nameStrutsExample/servlet-name servlet-classorg.apache.pluto.core.PortletServlet/servlet-class init-param param-nameportlet-class/param-name param-valueorg.apache.struts2.portlet.dispatcher.Jsr168Dispatcher/param-value /init-param init-param param-nameportlet-guid/param-name param-value StrutsExample.StrutsExamplePortlet /param-value /init-param /servlet servlet-mapping servlet-nameStrutsExample/servlet-name url-pattern/PlutoInvoker/StrutsExamplePortlet/url-pattern /servlet-mapping I was missing the portlet-name init-param.

It's possible. from http://java.sun.com/developer/technicalArticles/Servlets/servletapi2.3/ I found this: Class Loaders Here's a small change with a big impact: In API 2.3, a servlet container (a.k.a. the server) will ensure that classes in a Web application not be allowed to see the server's implementation classes. In other words, the class loaders should be kept separate. That doesn't sound like much, but it eliminates the possibility of a collision between Web application classes and server classes. That had become a serious problem because of XML parser conflicts. Each server needs an XML parser to parse web.xml files, and many Web applications these days also use an XML parser to handle reading, manipulation, and writing of XML data. If the parsers supported different DOM or SAX versions, that could cause an irreparable conflict. The separation of class scope solves this issue nicely. Which would indirectly support Jboss not being client, It's Serlvet 2.3 though... so maybe not. My understanding is that all web apps should have different class loaders. - Original Message - From: Jim Barrows [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Friday, August 20, 2004 12:54 PM Subject: RE: Deploying Struts ??? -Original Message- From: Lykins Don H Contr AFSAC/ITS [mailto:[EMAIL PROTECTED] Sent: Friday, August 20, 2004 8:47 AM To: 'Struts Users Mailing List' Subject: RE: Deploying Struts ???

Re: Deploying Struts ???
I thought so, but try renaming a .war file, and redeploying it, we had Smith.war and John.war, and whenever Smith deployed his war, all his classes would replace the ones that John had deployed before... The only solution we found was to split tomcat and jboss, and smith and john now have each one a local tomcat that connects to the JBOSS server using jndi.. it´s not the best.. but at least we don´t keep getting collision with the jsps Lucas - Original Message - From: Jim Barrows [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Friday, August 20, 2004 2:19 PM Subject: RE: Deploying Struts ??? -Original Message- From: Lucas Gonzalez Pearson [mailto:[EMAIL PROTECTED] Sent: Friday, August 20, 2004 10:15 AM To: Struts Users Mailing List Subject: Re: Deploying Struts ??? If you deploy two different war to a jboss server, the one that is deployed the latest will be used. I am experiencing this problem. Maybe Jboss classloader is does not support hierarchies? It's possible. from http://java.sun.com/developer/technicalArticles/Servlets/servletapi2.3/ I found this: Class Loaders Here's a small change with a big impact: In API 2.3, a servlet container (a.k.a. the server) will ensure that classes in a Web application not be allowed to see the server's implementation classes. In other words, the class loaders should be kept separate. That doesn't sound like much, but it eliminates the possibility of a collision between Web application classes and server classes. That had become a serious problem because of XML parser conflicts. Each server needs an XML parser to parse web.xml files, and many Web applications these days also use an XML parser to handle reading, manipulation, and writing of XML data. If the parsers supported different DOM or SAX versions, that could cause an irreparable conflict. The separation of class scope solves this issue nicely. Which would indirectly support Jboss not being client, It's Serlvet 2.3 though... so maybe not. My understanding is that all web apps should have different class loaders. - Original Message - From: Jim Barrows [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Friday, August 20, 2004 12:54 PM Subject: RE: Deploying Struts ??? -Original Message- From: Lykins Don H Contr AFSAC/ITS [mailto:[EMAIL PROTECTED] Sent: Friday, August 20, 2004 8:47 AM To: 'Struts Users Mailing List' Subject: RE: Deploying Struts ???

You can, but with any jar file that has to read or write to anything in the webapp, you cannot do it if the class is loaded from anyplace but the war. -Original Message- From: Jim Barrows [mailto:[EMAIL PROTECTED] Sent: Friday, August 20, 2004 11:43 AM To: Struts Users Mailing List Subject: RE: Deploying Struts ??? -Original Message- From: Lykins Don H Contr AFSAC/ITS [mailto:[EMAIL PROTECTED] Sent: Friday, August 20, 2004 8:25 AM To: 'Struts Users Mailing List' Subject: RE: Deploying Struts ??? so how do you suggest we deploy struts? each developer bundle struts in their own WAR files?

I thought so, but try renaming a .war file, and redeploying it, we had Smith.war and John.war, and whenever Smith deployed his war, all his classes would replace the ones that John had deployed before... The only solution we found was to split tomcat and jboss, and smith and john now have each one a local tomcat that connects to the JBOSS server using jndi.. it´s not the best.. but at least we don´t keep getting collision with the jsps Lucas - Original Message - From: Jim Barrows [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Friday, August 20, 2004 2:19 PM Subject: RE: Deploying Struts ??? -Original Message- From: Lucas Gonzalez Pearson [mailto:[EMAIL PROTECTED] Sent: Friday, August 20, 2004 10:15 AM To: Struts Users Mailing List Subject: Re: Deploying Struts ???

I am experiencing this problem. Maybe Jboss classloader is does not support hierarchies? I am not a JBoss user so this is hearsay, but my understanding is that the *default* JBoss configuration (the unified class loader) does not support hierarchies, but that there is a configuration option that turns this off -- and restores Tomcat's hierarchical class loader scheme. FYI, the way Tomcat does class loaders is not identical to all the other servers, but it's a useful example in understanding what servlet containers do for individual web apps: http://jakarta.apache.org/tomcat/tomcat-5.0-doc/class-loader-howto.html Craig - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
