Wicket 1.4.5 + Websphere Portal Express 6.1: query string parameters are not
forwarded through WicketPortlet
------------------------------------------------------------------------------------------------------------
Key: WICKET-2711
URL: https://issues.apache.org/jira/browse/WICKET-2711
Project: Wicket
Issue Type: Bug
Components: wicket-portlet
Affects Versions: 1.4.5
Environment: Windows XP SP3
jdk1.5.0_15
Wicket 1.4.5
Spring 2.5.2
Websphere Portal Express 6.1
Reporter: Uttam Phalnikar
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.
