creating pages using the API [Our Ref:CPTEE8C7 Your Ref:CPTB3A81]

hi there,

I've created a servlet in the Jahia context, from which I can get the 
sites base service (JahiaSitesBaseService.getInstance()), page base 
service (JahiaPageBaseService.getInstance()), etc -- the getInstance() 
methods work.  I now wish to call this servlet from my portlet.

I'm trying to create a page using the API.  It looks like I should use 
JahiaPageBaseService.createPage.  I'm having trouble constructing the last 
argument - ParamBean.

When running the servlet by typing in the URL in a browser, setting the 
parameter to NULL I get a NullPointerException.

I use the following code to run the servlet from my portlet:
        URL url = new 
URL("http://localhost:8080/jahia/CreatePersonalHomePage");
        HttpURLConnection con = (HttpURLConnection)url.openConnection();
        con.setRequestMethod("POST");
        con.setDoInput(true);
        con.setDoOutput(true);
        con.setUseCaches(false); 
        con.getInputStream();

In my servlet, I construct my parambean as follows -- I construct the 
parambean and call createPage from the "service" method of my servlet:
        ParamBean paramBean =
                new ParamBean(
                        request,
                        response,
                        this.getServletContext(),
                        settingsBean,
                        System.currentTimeMillis(),
                        1);

I construct settingsBean as follows:
        String licenseFilename =
 
"C:\\jahia404_build5822\\tomcat\\webapps\\jahia\\WEB-INF\\etc\\config\\license.xml";
        String propertiesFilename =
 "C:\\jahia404_build5822\\tomcat\\webapps\\jahia\\WEB-INF\\etc\\config";
        SettingsBean settingsBean =
                new SettingsBean(this.config, propertiesFilename, 
licenseFilename, 6131);

create page looks as follows:
        svc.createPage(
                1,
                0,
                JahiaPage.TYPE_DIRECT,
                "my personal page",
                25,
                "http://",
                0,
                "thepage",
                -8,
                paramBean);

Problem: the process appears to hang - the last output on my tomcat 
console is as follows:
 64297 DEBUG 
org.jahia.services.database.ConnectionDispenser.getConnection:195 - 
Retrieving new onnection from pool..
 64328 DEBUG org.jahia.bin.JahiaWebAppListener.sessionCreated:32 - Session 
093E81F94E6D374963AC8558475636FE was just created...
 64328 DEBUG org.jahia.params.ParamBean.getSiteInfos:1598 - Can't find 
site in serverName, trying to reverse from page ID...
 64328 DEBUG org.jahia.params.ParamBean.getSiteInfos:1647 - No site found 
in URL, serverName or via page ID, going to default site...

My browser displays an empty page, and looks like it is still waiting for 
a response (the icon in the top-right corner continues spinning).

Am I on the right track for creating pages? How should I construct 
paramBean?

thanks,
Manoj

Hi,

This is probably the same problem of trying to call the Jahia API from a 
servlet in another context. Please read the Web application developer 
guide.
