[Geervani BS, modifié il y a 13 années.]

Hello Experts,

I am using SAP JCo in liferay. So need to store some SAP related connection properties. I want to make it configurable. can we store these configuration settings in web.xml. If so How to retrieve(read) data from web.xml in the Portlet. Or what is the best way to do this.

Any help will be highly appreciated.

Thanks in advance
Sandhya

PortletBag portletBag = PortletBagPool.get(portletId);
ServletContext servletContext = portletBag.getServletContext();
String param = servletContext.getInitParameter("paramname");

Thanks for replying. But its not working. Its returning null for portletBag var. I am giving portletId from ThemeDisplay. I tried this in ProcessAction method

Afaik you cannot get a portletId from the themedisplay

what is the code you are using ? the portlet id is the value of the portlet-name element in your portlet.xml for suffixed with _WAR_manglednameofyourwar

if your war is named my-portlet-6.0.1.1 and it has a portlet with name 1 the portlet id will be

1_WAR_myportlet

so remove dashes and version strings from the war name

Hi,

I am using

ThemeDisplay themeDisplay = (ThemeDisplay)request.getAttribute(WebKeys.THEME_DISPLAY);
PortletDisplay portletDisplay= themeDisplay.getPortletDisplay();
String portletId= portletDisplay.getId();

PortletBag portletBag = PortletBagPool.get(portletId);
ServletContext servletContext = portletBag.getServletContext();
String param = servletContext.getInitParameter("myParam");


Based on your last reply I also tried

PortletBag portletBag = PortletBagPool.get("TimeAccount");
ServletContext servletContext = portletBag.getServletContext();
String param = servletContext.getInitParameter("contextClass");

TimeAccount is the value in <portlet-name>. But same null exception

by the way my web.xml is like this

<web-app>
...
...
<context-param>
<param-name>myParam</param-name>
<param-value>myParamValue</param-value>
</context-param>
...
...
</web-app>
