10.2.7 Accumulate commURIs from an Enterprise Directory for a User DN

The following code shows how to accumulate commURIs from an LDAP server for a User DN provided by a user. This is executed in Step 6 of Figure .

public static String collectCommURIs(String vName,

    DirContext vDirCtx, String bDN )

{

    String strCommURIs = new String("");

    try

    {

        String fltrEnterprise = "(&("+vName+") )";

        SearchControls ctlEnterprise = new SearchControls();

        ctlEnterprise.setSearchScope(SearchControls.SUBTREE_SCOPE);

        /* Set the returning attributes to commURI and CN */

        String[] entAttrs = {"commURI","cn"};

        ctlEnterprise.setReturningAttributes(entAttrs);

        String s1[] = ctlEnterprise.getReturningAttributes();

        /* Fetch the results containing commURI and CN specified

            in filter based on DN */

        NamingEnumeration commURIResult = vDirCtx.search(

            bDN,fltrEnterprise,ctlEnterprise);

        /* Iterate the results to count the number of commURIs

            and form a string that has commURIs for a UserDN */

        while(commURIResult.hasMore())

        {

            SearchResult srchCommRslt = (SearchResult)

                commURIResult.next();

            Attributes allAttrs = srchCommRslt.getAttributes();

            Attribute commURI = allAttrs.get("commURI");

            cntCommURIs = commURI.size();

            strCommURIs = commURI.toString();

        }

    }

    catch (NamingException e)

    {

        System.err.println("Error in collectCommURIs - " +

            e.getMessage());

    }

    return strCommURIs;

}
