I am trying to deploy a Wicket application as a portlet in Liferay 5.2.3
bundled with Tomcat 6.0.  I found this which has been very helpful:

r
<http://mail-archives.apache.org/mod_mbox/wicket-users/201001.mbox/brows
er> 

 

When I tried to add the application to my portal, this error was thrown:

 

Sep 28, 2010 4:42:18 PM org.apache.catalina.core.ApplicationDispatcher
invoke

SEVERE: Servlet.service() for servlet MyApp threw exception

java.lang.StringIndexOutOfBoundsException: String index out of range: -1

      at java.lang.String.substring(String.java:1937)

      at
org.apache.wicket.protocol.http.portlet.PortletServletRequestWrapper.mak
eServletPath(PortletServletRequestWrapper.java:71)

...

 

I thought this may have something to do with the url-pattern on my
filter-mapping.  Initially I set my web.xml to have this:

 

    <filter-mapping>

        <filter-name>MyApp</filter-name>

        <url-pattern>/myApp</url-pattern>

        <dispatcher>REQUEST</dispatcher>

        <dispatcher>INCLUDE</dispatcher>

        <dispatcher>FORWARD</dispatcher>    

    </filter-mapping>

 

and my portlet.xml to have:

 

    <portlet>

        <description>My App</description>

        <portlet-name>MyApp</portlet-name>

        <display-name>MyApp</display-name>

 
<portlet-class>org.apache.wicket.protocol.http.portlet.WicketPortlet</po
rtlet-class>

        <init-param>

            <name>wicketFilterPath</name>

            <value>/myApp</value>

        </init-param>

        ...

    </portlet>

 

 

So, I changed my web.xml to:

 

    <filter-mapping>

        <filter-name>MyApp</filter-name>

        <url-pattern>/myApp</url-pattern>

        <dispatcher>REQUEST</dispatcher>

        <dispatcher>INCLUDE</dispatcher>

        <dispatcher>FORWARD</dispatcher>    

    </filter-mapping>

 

and my portlet.xml to:

 

    <portlet>

        <description>My App</description>

        <portlet-name>MyApp</portlet-name>

        <display-name>MyApp</display-name>

 
<portlet-class>org.apache.wicket.protocol.http.portlet.WicketPortlet</po
rtlet-class>

        <init-param>

            <name>wicketFilterPath</name>

            <value>/myApp</value>

        </init-param>

        ...

    </portlet>

 

 

Unfortunately, that resulted in this error when trying to deploy the
application (and then it gets undeployed):

Does anyone know what could have caused the initial error assuming it
wasn't caused by the url-pattern/wicketFilterPath?

 

Any insight is great appreciated,
