My ultimate goal is to migrate an application to spring 4.1.4, Hibernate 4.3. But this was resulting to migrate Tiles 1.x to Tiles 2.x. But this intern was creating issues with Struts 1. With the help of Tiles user community, I was able to get the struts-tiles2-1.4.0-SNAPSHOT.jar
library and I'm trying to migrate a small sample application from Strits 1/Tiles 1 to Struts 1/Tiles 2. After making changes according to the suggestions in https://feima2011.wordpress.com/2011/04/27/struts-1-and-tiles-2-integration/ , I'm getting the following error while running the application in the browser. | Error 500--Internal Server Error | | java.lang.NullPointerException at org.apache.tiles.template.DefaultAttributeResolver.computeAttribute(DefaultAttributeResolver.java:42) at org.apache.tiles.template.InsertAttributeModel.resolveAttribute(InsertAttributeModel.java:187) at org.apache.tiles.template.InsertAttributeModel.start(InsertAttributeModel.java:107) at org.apache.tiles.jsp.taglib.InsertAttributeTag.doTag(InsertAttributeTag.java:306) at jsp_servlet.__index._jspService(__index.java:93) at weblogic.servlet.jsp.JspBase.service(JspBase.java:34) at weblogic.servlet.internal.StubSecurityHelper$ServletServiceAction.run(StubSecurityHelper.java:227) at weblogic.servlet.internal.StubSecurityHelper.invokeServlet(StubSecurityHelper.java:125) at weblogic.servlet.internal.ServletStubImpl.execute(ServletStubImpl.java:300) at weblogic.servlet.internal.TailFilter.doFilter(TailFilter.java:26) at weblogic.servlet.internal.FilterChainImpl.doFilter(FilterChainImpl.java:60) at oracle.security.jps.ee.http.JpsAbsFilter$1.run(JpsAbsFilter.java:119) at java.security.AccessController.doPrivileged(Native Method) at oracle.security.jps.util.JpsSubject.doAsPrivileged(JpsSubject.java:324) at oracle.security.jps.ee.util.JpsPlatformUtil.runJaasMode(JpsPlatformUtil.java:460) at oracle.security.jps.ee.http.JpsAbsFilter.runJaasMode(JpsAbsFilter.java:103) at oracle.security.jps.ee.http.JpsAbsFilter.doFilter(JpsAbsFilter.java:171) at oracle.security.jps.ee.http.JpsFilter.doFilter(JpsFilter.java:71) at weblogic.servlet.internal.FilterChainImpl.doFilter(FilterChainImpl.java:60) at oracle.dms.servlet.DMSServletFilter.doFilter(DMSServletFilter.java:163) at weblogic.servlet.internal.FilterChainImpl.doFilter(FilterChainImpl.java:60) at weblogic.servlet.internal.WebAppServletContext$ServletInvocationAction.wrapRun(WebAppServletContext.java:3729) at weblogic.servlet.internal.WebAppServletContext$ServletInvocationAction.run(WebAppServletContext.java:3695) at weblogic.security.acl.internal.AuthenticatedSubject.doAs(AuthenticatedSubject.java:321) at weblogic.security.service.SecurityManager.runAs(SecurityManager.java:120) at weblogic.servlet.internal.WebAppServletContext.securedExecute(WebAppServletContext.java:2285) at weblogic.servlet.internal.WebAppServletContext.execute(WebAppServletContext.java:2184) at weblogic.servlet.internal.ServletRequestImpl.run(ServletRequestImpl.java:1459) at weblogic.work.ExecuteThread.execute(ExecuteThread.java:209) at weblogic.work.ExecuteThread.run(ExecuteThread.java:178)In the tiles-defs.xml, I made the changes as below: (PUT changed to put-attribute) (definition path TO definition template) etc <definition name="baseLayout" template="/baseLayout.jsp"> <put-attribute name="title" value="Tiles Example" /> <put-attribute name="header" value="/header.jsp" /> <put-attribute name="menu" value="/menu.jsp" /> <put-attribute name="body" value="/body.jsp" /> <put-attribute name="footer" value="/footer.jsp" /> </definition> <definition name="friends" extends="baseLayout"> <put-attribute name="title" value="Friends" /> <put-attribute name="body" value="/friends.jsp" /> </definition> <definition name="office" extends="baseLayout"> <put-attribute name="title" value="The Office" /> <put-attribute name="body" value="/office.jsp" /> </definition> In Jsp's I changed the tag <tiles:insert name="header" ignore="true" /> TO <tiles:insertAttribute name="header" ignore="true" /> Also in struts-config file,<controller processorClass="org.apache.struts.tiles2.TilesRequestProcessor"/>AND<plug-in className="org.apache.struts.tiles2.TilesPlugin" > I do have the following jar in my WEB-INF/lib and classpathstruts-core-1.4.0-SNAPSHOT.jar struts-tiles2-1.4.0-SNAPSHOT.jar struts-extras-1.4.0-SNAPSHOT.jar struts-scripting-1.4.0-SNAPSHOT.jar struts-taglib-1.4.0-SNAPSHOT.jar struts-tiles-1.4.0-SNAPSHOT.jar tiles-api-2.2.1.jar tiles-jsp-2.2.1.jar tiles-servlet-2.2.1.jar tiles-template-2.2.0.jar log4j-1.2.16.jar slf4j-api-1.7.7.jar slf4j-log4j12-1.7.7.jar jakarta-oro.jar I have removed the struts.jar earlier, but with and without struts.jar, I'm getting the same error.Can any friends be a help on this issue?
