java - Accessing oracle database via SID through JDBC without host:port -


when i'm looking information on how connect oracle database via jdbc, find same solutions show how connect known host:port. have pass connect string 

 jdbc:oracle:thin:[user/password]@[host][:port]:sid

to jdbc , works.

protected connection connect() {     connection conn;      try     {         class.forname(oracle.jdbc.oracledriver.class.getcanonicalname());     }     catch (classnotfoundexception e)     {         return null;     }      try     {         conn = drivermanager.getconnection("jdbc:oracle:thin:@1.1.1.1:1536:sid", "user", "passwd");     }     catch (sqlexception e)     {         return null;     }      return conn; }

the problem approach though is, have find out on host:port database is. when use database tools pl/sql developer or others, don't need this. user prompted database name , the tool can somehow connect nevertheless. know how done. achieve requiring tnsping in path, , in helper class (not shown in above example code), provides connect url, call tnsping , parse output. not method, , wondering if there proper way connect.

you not able using normal jdbc (thin driver). may try using oci, apparently understand tns entries.

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
