There is a bug cause the error you get at 6.4.0 https://issues.apache.org/jira/plugins/servlet/mobile#issue/WW-5419
You can set init param at web.xml or change where you store tiles.xml to fix issue if you want to use 6.4.0 But Im not sure what cause you get error at 6.6.0 You might need turn struts.xml devMode to true and open log to trace for more detail Maybe other people can help you Best regards Heikki Hyyrö <heikki.hy...@tuni.fi> 於 2024年10月1日 週二 下午6:38 寫道： > Our web application based on Struts 2 + Tiles framework starts to give > errors on some jsp pages if I try to use a newer Struts version than > 6.3.0.2. > > Exactly the same codebase works fine on previous Struts versions (the > only changes are in the pom file and concern the versions of > struts2-core, struts2-tiles-plugin, struts2-config-browser-plugin and > strutrs2-json-plugin). > > On 6.6.0 the stacktrace has snippets like: > > > Caused by: org.apache.tiles.request.render.CannotRenderException: > > java.io.IOException: JSPException including path 'xyz.jsp'. > > at > > > org.apache.tiles.core.impl.BasicTilesContainer.render(BasicTilesContainer.java:395) > > ... > > Caused by: java.io.IOException: java.io.IOException: JSPException > > including path 'xyz.jsp'. > > at > > > org.apache.tiles.request.servlet.ServletUtil.wrapServletException(ServletUtil.java:56) > > at > > org.apache.tiles.request.jsp.JspRequest.doInclude(JspRequest.java:118) > > ... > > Caused by: java.lang.NullPointerException > > at > > > org.apache.struts2.components.IteratorComponent.start(IteratorComponent.java:309) > > at > > > org.apache.struts2.views.jsp.ComponentTagSupport.doStartTag(ComponentTagSupport.java:51) > where xyz is a path to a jsp file of ours. > > Curiously, Struts 6.4.0 stacktrace for the very same page gives a > different error: > > > HTTP ERROR 500 Cannot find definition named 'nodeGradesView.page' > > Caused by: org.apache.tiles.core.definition.NoSuchDefinitionException: > > Cannot find definition named 'xyz.page' > > at > > > org.apache.tiles.core.impl.mgmt.CachingTilesContainer.render(CachingTilesContainer.java:108) > > ... > > where xyz.page is a tiles definition of the view that xyz.jsp would > belong to. > > These errors are a bit cumbersome and have left as stuck at Struts > version 6.3.0.2. > > Best regards > > Heikki > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: user-unsubscr...@struts.apache.org > For additional commands, e-mail: user-h...@struts.apache.org > >
