[Installation, Configuration & Deployment] - WAR as JBOSS Context root app but using Struts

by marcelo.leite

Hi, I have a simple web app as a WAR file. It was developed using Struts and Tiles. My index JSP is composed by some calls to Tiles tags like this: <tiles:insert attribute="header"/> The app works well. But when i defined it as the Jboss context root app it stops to work. I've just see my config files like struts-config.xml, web.xml, tiles-defs.xml and jboss-web.xml and this is OK. Should i do some special configuration on any of this files? This is the error: org.apache.jasper.JasperException: Exception in JSP: /index.jsp:14 11: 12: 13: 14: <tiles:insert attribute="header"/> 15: 16: 17: Stacktrace: org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:504) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:393) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264) javax.servlet.http.HttpServlet.service(HttpServlet.java:810) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) root cause java.lang.NullPointerException org.apache.struts.taglib.tiles.InsertTag.processAttribute(InsertTag.java:689) org.apache.struts.taglib.tiles.InsertTag.createTagHandler(InsertTag.java:489) org.apache.struts.taglib.tiles.InsertTag.doStartTag(InsertTag.java:451) org.apache.jsp.index_jsp._jspx_meth_tiles_insert_0(index_jsp.java:186) org.apache.jsp.index_jsp._jspx_meth_html_html_0(index_jsp.java:109) org.apache.jsp.index_jsp._jspService(index_jsp.java:69) org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97) javax.servlet.http.HttpServlet.service(HttpServlet.java:810) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:332) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264) javax.servlet.http.HttpServlet.service(HttpServlet.java:810) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) Can you help me?

[JBoss Portal] - Re: Portlet navigation with CMS.

by Antoine_h

Yes... that is a common "UI navigation feature" requierement. you go from a page to another one, and want the menu to show also the new "active" page. you need two things, for which the JSR-168 does not give much help. (but read it anyway... to know what it provide and what to add to it in your own portal). 1) IPC : inter portlet communication. To have the portlet that change it's status (ie: in it's processAction method) warn the others that it has changed. The portlets may share (or send each other) a "fooState" instance that tell them all the properties of the current state. If they share, it is a "message" IPC. if they send an action, it is more a "event" IPC. 2) caching : if you want these portlet to refresh even if an actionURL did not called them, you may suppress the cache for them. but then, you loose the cache advantage. so to keep it, the best is to reset the cache of the target portlet, when necessary. for 1) : see the IPC feature, in JSR-168 draft version 2 and in jboss portal 2.6. These feature of IPC have been developped in these version. With current version, you can also have a look at : http://www.doc.ic.ac.uk/~mo197/portlets/portlet_messaging/ I have done something like that to have a menu "follow" the change in the portal général UI changes. for 2) : i am looking at this right now. coming to the forum to see what's about caching mecanism, and how to adapt it to comply with this need. the need to reset the cache of one portlet with "a command" is not in the JSR-168. I guess this can be done. don't know if it will be easy ... and quite clean programming. about cache : use the 2.4 SP1 where caching has been debugged intensively. hope it helps.

[JBossCache] - Re: How to use JBoss TreeCache outside JBoss Application Ser

by manik.surtani＠jboss.com

Apologies, only just realised that you are using 1.4.1.GA. If this is the case, the 1.4.1.GA docs are on http://labs.jboss.com/jbosscache. Also refer to the examples, etc. in the distribution.

1) Update to the latest JBoss Cache (2.0.0.ALPHA2) 2) Read the snapshot 2.0.0 user guide, especially the basic API.

[JBossCache] - Re: Configuration problems For PojoCache under JBoss AS

by manik.surtani＠jboss.com

This is a simple issue. Make sure you have aspectised the objects you want to cache. See PojoCache tutorials and examples for details.

[JBossCache] - Re: JDBCCacheLoader error: Io exception: The Network Adapter

by manik.surtani＠jboss.com

You could be running out of DB connections or your DB may not be recycling connections quickly enough. That loop of yours will put sufficient strain on any DB's connection manager! Try using an app server's connection pool (by providing a datasource when configuring the cache loader) or wait for JBCACHE-802.

[JBossCache] - Re: how to syn JBossCache with the database

by manik.surtani＠jboss.com

No, I can't. 1) I have no idea what your app is about or how it works 2) I don't want to take all the fun away from you!! Write a thread or something to poll the db and check for updates. You may need a versioning field or a tstamp. Alterlatively, have the app that DOES change the DB somehow inform your app. Perhaps via a messaging system. Then have your app remove appropriate portions from the cache.

Are you using JBossWS 1.0.x (JAX RPC)? If so, make LoanProcessor extend java.rmi.Remote View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4008394#4008394 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4008394
