Couldn't Create Managed Connection

Question

Hi,
I have developed a webdynpro application using webservice.and it works fine in portal...
But whenever the connection exceeds its limit,It throws the following Exception
Couldn't create ManagedConnection with . {jco.client.passwd=**, jco.client.lang=EN, jco.client.sysnr=00, jco.client.client=800, jco.client.ashost=server, jco.client.user=user1, jco.client.type=A, jco.client.jra_conn=true}
Then we have to increase the maximum number of connection in Visual administrator..
Although we have already close the connection in Webservice,
The connection remains in the same state(open),and throws the above Error.
Is There any way to solve this?
Regards
Nandha.

Hi Nandhadevi
Ok. The first thing I would do is to move the following two lines of code outside the while loop:
interaction.close();
connection.close();
then I would also as a precaution put both the interaction and connection object to null.
interaction = null;
connection = null;
In reality I would put the code like this (see below) so that we always close the connection even if an exception is thrown.
InitialContext initialcontext = new InitialContext();
ConnectionFactory connectionfactory=(ConnectionFactory) initialcontext.lookup("java:comp/env/eis/SAPJRAFactory");
Connection connection = null;
Interaction interaction= null;
try
connection = connectionfactory.getConnection();
RecordFactory recordFactory=connectionfactory.getRecordFactory();
MappedRecord input = recordFactory.createMappedRecord("ZVP_BAPI_GETPLANT_DETAIL");
input.put("CO_CODE",cocode);
Interaction interaction=connection.createInteraction();
output=(MappedRecord)interaction.execute(null,input);
ResultSet rs=(ResultSet)output.get("OUTPUT");
while(rs.next())
plant = rs.getString("PLANT");
plantname = rs.getString("NAME");
ZVP_Bapi_Getplant_WSgandS gs= new ZVP_Bapi_Getplant_WSgandS();
gs.setPlant(plant);
gs.setPlantname(plantname);
results.add(gs);
catch( Exception e )
// Some logging
finally
  if( interaction != null )
    interaction.close();
    interaction = null;
  if( connection != null )
    connection.close();
    connection = null;
