Hi all,
after successfully working with jetspeed 1.5 and implementing some static
portlets, I want to go a step further and create dynamic portlets with forms.
Unfortunately I have a problem, I cannot understand and solve, because I think
I already elimitated the mistakes. Still it does not work.
My understanding regarding parameters/forms is:
- they are primarily used to pass data/information from a portlet to another
portlet or to the portlet itself. I can achieve this by registering parameters
in the portlet registry entry or do it dynamically in the code(? I am not sure
on this one). I get and set parameters using the "rundata".
- Processing forms' data/information is done with the action.class for the
specific portlet, which is declared under the portlet registry
entry "<parameter action="XYZaction.class"/>". The action specific method in
this class is invoked by declaring it in the form's INPUT(submit-button), e.g.
<FORM>
<INPUT TYPE="SUBMIT" NAME="eventSubmit_dorefresh" VALUE="Refresh" >
</FORM>
The problem is:
I cannot get
a) the parameter value of the portlet
b) the submitted form values of the portlet.
Why am I wrong? I mean, which important point am I missing?
I can get to see all attributes of the portlet, like JSPID, SSL Session, and
so on, but not the one I defined!!
The do refresh code looks like this:
public void doRefresh(RunData rundata, Portlet portlet)
{
String temp = "";
temp = rundata.getParameters().getString("sql");
PortletSessionState.setAttribute(portlet, rundata, "sql", temp);
}
"sql" is a parameter I defined in the portlet:
<parameter name="sql" value="select * from test" hidden="false"
cachedOnName="true" cachedOnValue="true">
<security-ref parent="admin-only"/>
<meta-info>
<title>SQL Query</title>
<description>A descr.</description>
</meta-info>
</parameter>
I want to access it in the template.jsp:
if(rundata == null)
out.write("No Data to run!");
else
{
for (Enumeration e = request.getAttributeNames(); e.hasMoreElements();)
{
out.write(e.nextElement().toString() + " <br>");
}
out.write("---------------- <br>");
out.write("SSL Session: " + (String)
request.getAttribute "javax.servlet.request.ssl_session") + "<br>");
out.write("PEID: " + (String) request.getAttribute("js_peid") + "<br>");
out.write("TEMPLATE: " + (String) request.getAttribute("template") + "<br>");
out.write("SQL: " + (String) request.getAttribute("sql") + "<br>");
}
The last out.write results in "Null" and I don't have any idea.
Any help appreciated and more than welcome :o)
Ciao,
Tommaso
