nullpointer by invoking web service and RPCMessageReceiver problem
-------------------------------------------------------------------
Key: AXIS2-2775
URL: https://issues.apache.org/jira/browse/AXIS2-2775
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Environment: window xp
jdk5
axis2
eclipse3.2
Reporter: haha
I have the Problem by invoking the Web Service with axis2,
------------------------Client:
public void MyConnection(String user, String passwd)throws RemoteException{
Options options = new Options();
options.setManageSession(true);
RPCServiceClient serviceClient = new RPCServiceClient();
options.setTo(targetEPR);
options.setAction("urn:MyConnection");
options.setExceptionToBeThrownOnSOAPFault(false);
serviceClient.setOptions(options);
QName opSet = new QName("http://services.solver.nx.wp.com/xsd", "MyConncetion");
Object response = serviceClient.invokeBlocking(opSet,new Object[] {user,passwd});
if(response instanceof AxisFault)
{
throw (RemoteException)response;}
}
-----------------------------------------------------------------------------
-------------------------Service
public void MyConnection(String user, String passwd) throws AxisFault
{
String connString = Const.getCONNECTIONSTRING();
if(connString == null)
{
throw new AxisFault("Unknown server defined in web.xml.");
}
MessageContext mctx =MessageContext.getCurrentMessageContext();
TransportListener listener = mctx.getTransportIn().getReceiver();
SessionContext session = listener.getSessionContext(mctx);
MessageContext.getCurrentMessageContext().setSessionContext(session);
System.out.println("the session is:" + session +" ;and the sessionpropertiers is: "+session.getProperties().size());
session.getProperties().remove(Const.SESSIONUSER);
session.getProperties().remove(Const.SESSIONCUSTOMER);
Connection conn;
try
{
Class.forName(Const.DBDRIVERCLASS);
}
catch(ClassNotFoundException cnfe)
{
terminate();
throw new AxisFault("Database Driver-class not found.");
}
try
{
conn = DriverManager.getConnection(connString, user, passwd);
}
catch(SQLException sqle)
{
terminate();
throw new AxisFault("Connection as admin could not be established.\n" + connString + " User: " + user);
}
DBHandler dbHandler = new DBHandler();
try
{
ResultSet result = dbHandler.performSelect(Const.getDBSQLUSERCUST(user), conn);
if(!result.next())
{
conn.close();
terminate();
throw new AxisFault("The user is not linked with a customer.");
}
session.setProperty(Const.SESSIONUSER, result.getString(Const.DBCOLUSERNAME));
session.setProperty(Const.SESSIONCUSTOMER, new Integer(result.getInt(Const.DBCOLCUSTID)));
}
catch(SQLException sqle)
{
try
{
conn.close();
}
catch(SQLException sqle2)
{
terminate();
throw new AxisFault("Error while closing the connection.");
}
terminate();
throw new AxisFault("Error while getting user and customer from database.");
}
try
{
conn.close();
}
catch(SQLException sqle)
{
terminate();
throw new AxisFault("Error while closing the connection.");
}
}
----------------------------------------------------------
------------------------------------------the Problem:
sessionContext.getproperties() is always null

Posted by "haha (JIRA)" <ji...@apache.org>.

haha reopened AXIS2-2775:
-------------------------
Thanks for your helps very much.
I have no more those failures, but i don't know why, i guess, that the "RPCMessageReceiver" caused this, it needs always a returnvalue, so i did the follows:
I changed the "public void MyConnction()" on the Server side to "public Boolean MyConnection()" with "return true", and on the client side i changed the code to:
public void MyConnection(String user, String passwd)throws RemoteException{
Options options = new Options();
RPCServiceClient serviceClient = new RPCServiceClient();
options.setTo(targetEPR);
options.setAction("urn:MyConnection");
serviceClient.setOptions(options);
options.setExceptionToBeThrownOnSOAPFault(false);
QName opSet = new QName("http://services.solver.nx.wp.com/xsd", "MyConnection");
Object[] response = serviceClient.invokeBlocking(opSet,new Object[] {user,passwd},new Class[]{Boolean.class});
Boolean result =(Boolean)response[0];
if (result == false)System.out.println("no results!");
else
System.out.println("Result "+ result);
if(response[0] instanceof AxisFault)
{
throw (RemoteException)response[0];
}
}
---------------------------------------------------------------
so this time it works fine, but only local and only inside the Eclipse. If i put the Service and the client Programm onto differente Computers, it doesn't work any more, there occurt a Exception "AxisFault: Connection refused: connect". How can i set the structure of the Client and the Server side? must be a Tomcat Server on cleint side Computer installed? can you tell me please?

haha edited comment on AXIS2-2775 at 6/12/07 2:26 AM:
------------------------------------------------------
Thanks for your helps very much.
I have no more those failures, but i don't know why, i guess, that the "RPCMessageReceiver" caused this, it needs always a returnvalue, so i did the follows:
I changed the "public void MyConnction()" on the Server side to "public Boolean MyConnection()" with "return true", and on the client side i changed the code to:
public void MyConnection(String user, String passwd)throws RemoteException{
Options options = new Options();
RPCServiceClient serviceClient = new RPCServiceClient();
options.setTo(targetEPR);
options.setAction("urn:MyConnection");
serviceClient.setOptions(options);
options.setExceptionToBeThrownOnSOAPFault(false);
QName opSet = new QName("http://services.solver.nx.wp.com/xsd", "MyConnection");
Object[] response = serviceClient.invokeBlocking(opSet,new Object[] {user,passwd},new Class[]{Boolean.class});
Boolean result =(Boolean)response[0];
if (result == false)System.out.println("no results!");
else
System.out.println("Result "+ result);
if(response[0] instanceof AxisFault)
{
throw (RemoteException)response[0];
}
}
---------------------------------------------------------------
so this time it works fine, but only local and only inside the Eclipse. If i put the Service and the client Programm onto two different Computers(i want to run it remote), it doesn't work any more, there occurt a Exception "AxisFault: Connection refused: connect", even though i had started the server. (I used the command "axis2.bat" under axis2\bin on client side). How can i set the structure of the Client and the Server side? must be a Tomcat Server on cleint side Computer installed? can you tell me please?

[jira] Issue Comment Edited: (AXIS2-2775) nullpointer by invoking
web service and RPCMessageReceiver problem
Posted by "haha (JIRA)" <ji...@apache.org>.

haha edited comment on AXIS2-2775 at 6/12/07 2:23 AM:
------------------------------------------------------
Thanks for your helps very much.
I have no more those failures, but i don't know why, i guess, that the "RPCMessageReceiver" caused this, it needs always a returnvalue, so i did the follows:
I changed the "public void MyConnction()" on the Server side to "public Boolean MyConnection()" with "return true", and on the client side i changed the code to:
public void MyConnection(String user, String passwd)throws RemoteException{
Options options = new Options();
RPCServiceClient serviceClient = new RPCServiceClient();
options.setTo(targetEPR);
options.setAction("urn:MyConnection");
serviceClient.setOptions(options);
options.setExceptionToBeThrownOnSOAPFault(false);
QName opSet = new QName("http://services.solver.nx.wp.com/xsd", "MyConnection");
Object[] response = serviceClient.invokeBlocking(opSet,new Object[] {user,passwd},new Class[]{Boolean.class});
Boolean result =(Boolean)response[0];
if (result == false)System.out.println("no results!");
else
System.out.println("Result "+ result);
if(response[0] instanceof AxisFault)
{
throw (RemoteException)response[0];
}
}
---------------------------------------------------------------
so this time it works fine, but only local and only inside the Eclipse. If i put the Service and the client Programm onto differente Computers, it doesn't work any more, there occurt a Exception "AxisFault: Connection refused: connect". (I used the command "axis2.bat" under axis2\bin). How can i set the structure of the Client and the Server side? must be a Tomcat Server on cleint side Computer installed? can you tell me please?

[jira] Resolved: (AXIS2-2775) nullpointer by invoking web service
and RPCMessageReceiver problem
Posted by "Deepal Jayasinghe (JIRA)" <ji...@apache.org>.

Deepal Jayasinghe resolved AXIS2-2775.
--------------------------------------
Resolution: Fixed
First you do not need to get the session context as you have done , you can just get the session context from the MessageContext.
MessageContext mctx =MessageContext.getCurrentMessageContext();
TransportListener listener = mctx.getTransportIn().getReceiver();
SessionContext session = listener.getSessionContext(mctx);
MessageContext.getCurrentMessageContext().setSessionContext(session);
And other thing is you have only valid session context only if you have deploy your service in transport session. So please try to do the following,
First deploy your service in transport session
Get the session context from the messagecontext.
MessageContext.getCurrentMessageContext().getSessionContext();
I will resolve the issues , since the error is due to user code. Please try to follow the steps that I mentioned and please re-open the issue if the issue is still there.
