Axis2 RPC bug

Prótár Gábor Wed, 20 Sep 2006 07:46:25 -0700

Hello!

I have found a bug int he RPC style webservice handling.

I am using Tomcat v5.5.17, Axis 2 v1.0, MySQL v5.0.24, MySQL Connector/J v5.0.3

If I change the return value of pay web method, then everything works. But I would like to have a String return type. Nothing else changes, but the web method is not working, throws an exception.

Thanks,

Gábor

The details:

1.a.: The web method code:

- - - - - - - - - - - - - - - - - - - - - - - - - - - service code - - - - - - - - - - - - - - - - - - - - - - - - - - -

public String pay(Payment[] transactions) throws Exception

{

String ret = "";

for(int i = 0; i <= transactions.length; i++)

{

//System.err.println("a(z) " + i + "-ik név = " + transactions[i].getName());

Context initContext = new InitialContext();

if ( initContext == null )

ret += "no init context; ";

Context envContext = (Context)initContext.lookup("java:/comp/env");

if ( envContext == null )

ret += "no enc context; ";

DataSource ds = (DataSource)envContext.lookup("jdbc/TestDB");

if ( ds == null )

ret += "no datasource; ";

Connection conn = ds.getConnection();

if (conn == null )

ret += "no conncetion; ";

Statement ins = conn.createStatement();

ins.execute("insert into w(name) values('" + transactions[i].getName() + "')");

conn.commit();

conn.close();

}

return ret;

}

wsdl2java -uri http://localhost:8080/axis2/services/ws?wsdl

Pay tomb = new Pay();

Payment p1 = new Payment();

p1.setName("name1");

p1.setAmount(5);

tomb.addParam0(p1);

Payment p2 = new Payment();

p2.setName("name2");

p2.setAmount(6);

tomb.addParam0(p2);

//ws.pay(tomb);

PayResponse rr = ws.pay(tomb);

System.out.println(rr.get_return());
