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 -
