问题


I am following answer posted here. OGNL and wildcards working in tiles definitions with struts2-tiles-plugin?

If you know the answer, would apprecite if you tell me how to use freemarker with it. If don't even than I accept the answer if you solve my problem to make the code work.

Everything is same but 

Struts2 & Tiles plugin - 2.3.4.1

Conclusion

if you use it with Glassfish as tested with the code is working fine BUT

After alot of testing and checking, the problem is with embedded tomcat7 instance which is not working with the above web.xml configuration and genertating error. Below is the pom.xml plugin that if run tomcat7:run will generate the error. Not sure whats the problem.

 <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <version>2.0</version>
                <configuration>
                    <port>8000</port>
                </configuration>
            </plugin>

回答1:


Note: The following has been tested to work (struts2 with tiles 2.2.2 and freemarker). Due to time constraints this solution works with struts2 2.3.1.2 and the struts2-tiles-plugin-2.3.1.2 but NOT higher versions. Tried 2.3.4.1 and something broke.

Set up the following: OGNL and wildcards working in tiles definitions with struts2-tiles-plugin?

Add freemarker support for tiles:

Artifact: tiles-freemarker, Group: org.apache.tiles, Version: 2.2.2

Extending the test from the previous example to incorporate a freemarker title into the demo: Add /WEB-INF/content/tiles/test.ftl which contains:

<#assign s=JspTaglibs["/struts-tags"] /> 
<@s.textfield name="test"/>

One line has been added to tiles.xml <put-attribute name="body" value="/WEB-INF/content/tiles/test.ftl"/> under the WILDCARD:package/* definition.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE tiles-definitions PUBLIC
       "-//Apache Software Foundation//DTD Tiles Configuration 2.1//EN"
       "http://tiles.apache.org/dtds/tiles-config_2_1.dtd">
<tiles-definitions>
    <definition name="baseLayout" template="/WEB-INF/content/tiles/template.jsp">
        <put-attribute name="title" value="Default Title"/>
        <put-attribute name="header" value="/WEB-INF/content/tiles/header.jsp"/>
        <put-attribute name="body" value="/WEB-INF/content/tiles/body.jsp"/>
        <put-attribute name="footer" value="/WEB-INF/content/tiles/footer.jsp"/>
        <put-attribute name="variable"  expression="OGNL:greeting"/>
    </definition>
    <definition name="test" extends="baseLayout">
        <put-attribute name="title" value="Test Title"/>
    </definition>
    <definition name="WILDCARD:package/*" extends="baseLayout">
        <put-attribute name="title" value="{1}" type="string"/>
        <put-attribute name="body" value="/WEB-INF/content/tiles/test.ftl"/>
    </definition>
    <definition name="" extends="baseLayout">
    </definition>
</tiles-definitions>

Test it:

My applicaton context is http://localhost:8080/Struts2Tiles2_2_2Example/ appending package/bla we have http://localhost:8080/Struts2Tiles2_2_2Example/package/blaand we will see a text field rendered by velocity incorporated into the view, and the title bar will say 'bla'.
