Portable Postgre on Linux

I will show below a simple and easy way to create a postgre database on linux, I used portable database. In the bottom there are some instructions which differ for windows.

Download 

Download portable postgre for linux from link: Postgre Binaries
Untar the file using:

 $ tar -xvf postgresql-9.2.1-1-linux-binaries.tar.gz  

It will create the folder ./pgsql

Generating database files Then create the folder where you want your database to be created:

 $ mkdir -p pgsql/data  

Run initDB to create the database files into the recently created folder: $ pgsql/bin/initdb -D pgsql/data -U postgres -A trust

Startup and shutdown 

To startup or shut down the database use: "-l logfile" is to setup the log file for the startup command. "-m fast" will stop the database and will not wait for other threads to stop before shut down the database For other commands, check

 $ pgsql/bin/pg_ctl --help  

Configuring port 

The initdb command will create several files within data folder.
To setup the port where the database will listen to, do the following:

1. Edit the generated file: pgsql/data/postgresql.conf 
2. Search for the line #port = 5432
3. Uncomment to your preferred port number: port = 5439

This way every time the database from that folder "pgsql/data" is started, it will run in the choosen port. No need for further configuration. Alternatively you can set a different port on every startup by setting up the environment param PGPORT, like below, just before the start command.

 $ export PGPORT=5439  

Create database and tables 

To create the database/tables etc, you can use pgsql/bin/psql and then simply run the sql commands, see example below:

 $ pgsql/bin/pg_ctl -D pgsql/data -l logfile start &  
 [1] 29063  
 $ server starting  
 $ pgsql/bin/psql -p 5439 -U postgres  
 postgres=# help  
 You are using psql, the command-line interface to PostgreSQL.  
 Type: \copyright for distribution terms  
     \h for help with SQL commands  
     \? for help with psql commands  
     \g or terminate with semicolon to execute query  
     \q to quit  
 postgres=# create database myportal;  
 CREATE DATABASE  
 postgres=# \c myportal;  
 You are now connected to database "myportal" as user "postgres".  
 myportal=# create table myexample (key integer default 0);  
 CREATE TABLE  
 myportal=# \dt  
       List of relations  
  Schema |  Name  | Type | Owner  
 --------+-----------+-------+----------  
  public | myexample | table | postgres  
 (1 row)  
 myportal=# select * from myexample;  
  key  
 -----  
 (0 rows)  
 myportal=# \q  
 $  

To change password for the user postgre, run psql and then:

 postgres=# \password postgres;  

Windows Experience 

You can do basically the same thing, the difference is that instead of using pgsql/bin/psql, you can use pgsql/bin/pgAdmin3.exe to connect to the database and create the database and tables

JAVA wsimport

Using wsimport to create client port to access a web service

There are 2 simple ways: download the wsdl xml file, or connect directly to wsdl url.

Needless to say you should go with the easiest way for you, e.g., if the WSDL is behind SSL connection you will find 1st option easier otherwise you would need aditional configuration to connect to the URL.

Option 1: you have the WSDL XML file

 /bin/wsimport.exe c:\wsdl.xml -verbose -s generatedSrc -wsdllocation  wsdl.xml

• c:\wsdl.xml the WSDL file you downloaded
• is the path to your JDK_HOME, I used 1.6.0_33
• -verbose is to turn on verbose mode, so you can see details if a step fails 
• -s is the option to set the destiny of the generated code 
• generatedSrc is the path where you want your generated code to be created 
• As you downloaded the WSDL file, you MUST use "-wsdllocation" option. Because if you don't use, wsimport will not create the javax.xml.ws.Service implementation class. 

If you get below error:

 [WARNING] Ignoring SOAP port "CadConsultaCadastro2Soap12":   
 it uses non-standard SOAP 1.2 binding.  
 You must specify the "-extension" option to use this binding.  
  line 59 of file:/C:/wsdl/cadconsultacadastro2.asmx.xml  
 [WARNING] Service "CadConsultaCadastro2" does not contain any usable ports.   
 try running wsimport with -extension switch.  
  line 58 of file:/C:/wsdl/cadconsultacadastro2.asmx.xml  

You will have to ignore SOAP12 by using "-extension" option:

 /bin/wsimport.exe c:\wsdl.xml -verbose -extension 

If the WS you are trying to connect uses headers, you should use "-XadditionalHeaders" option.

 /bin/wsimport.exe c:\wsdl.xml -verbose -extension -XadditionalHeaders

Option 2: you DO NOT have the WSDL XML file

 /bin/wsimport.exe  -verbose




•  is the actual Web Service's URL
