Description

In my application, I am using portlet init parameter "viewPage" to define view page URL with query string parameter. For e.g.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
<portlet>
<description>My Test</description>
<portlet-name>Test</portlet-name>
<display-name>Test</display-name>
<portlet-class>org.apache.wicket.protocol.http.portlet.WicketPortlet</portlet-class>
<init-param>
<name>wicketFilterPath</name>
<value>/test</value>
</init-param>
<init-param>
<name>viewPage</name>
<value>/test?portletid=portlet1</value>
</init-param>
<supports>
<mime-type>/</mime-type>
<portlet-mode>VIEW</portlet-mode>
</supports>
<portlet-info>
<title>Test Portlet</title>
<keywords>Wicket</keywords>
</portlet-info>
</portlet>
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
In my web.xml, I have filter mapping that maps "/test/*" to WicketFilter. The home page of my application displays appropriate contents on the basis of "portletid".

This setup works fine with JBoss Portal 2.7.2, but with Websphere Portal Express 6.1, my home page never gets the "portletid" parameters.

After investigation, it was realized that org.apache.wicket.protocol.http.portlet.PortletServletRequestWrapper has logic to obtain the querystring from wrapped request, but doesnt override methods getParameterMap / getParameters & getParameter to convert query string into parameters. I am not very sure whether Websphere Portal Server has any setting to do this conversion.

Here is the workaround that I have used
1. Created MyServletWebRequest that extends ServletWebRequest
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
public class MyServletWebRequest extends ServletWebRequest {
private Map<String, String[]> paramMap;

public MyServletWebRequest(HttpServletRequest httpServletRequest) {
super(httpServletRequest);
if (httpServletRequest instanceof PortletServletRequestWrapper) {
String qs = this.getQueryString();
if (StringUtil.hasLength(qs)) {
paramMap = new HashMap<String, String[]>();
StringTokenizer tokens = new StringTokenizer(qs, "&");
while (tokens.hasMoreTokens()) {
String tuple = tokens.nextToken();
int index = tuple.indexOf("=");
if (index != -1) {
String key = tuple.substring(0, index);
String value = tuple.substring(index + 1);
paramMap.put(key, new String[]

{ value }

);
}
}
} else

{ paramMap = Collections.EMPTY_MAP; }

}

}

@Override
public Map getParameterMap()

{ Map<String, String[]> combinedMap = new HashMap<String, String[]>(super.getParameterMap()); combinedMap.putAll(paramMap); return combinedMap; }

@Override
public String getParameter(String key)

{ if (paramMap.containsKey(key)) return paramMap.get(key)[0]; return super.getParameter(key); }

@Override
public String[] getParameters(String key)

{ if (paramMap.containsKey(key)) return paramMap.get(key); return super.getParameters(key); }

}
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

2. Then updated the MyWebApplication class (extends WebApplication) to override newWebRequest method
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
@Override
protected WebRequest newWebRequest(HttpServletRequest servletRequest)

{ return new MyServletWebRequest(servletRequest); }

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
That has solved the issue.

I think PortletServletRequestWrapper should override getParameterMap / getParameters & getParameter methods.
