INTRODUCTION:

This project provides a wrapper on the TigerLogic provided MVSP Java connectors
to allow for connection pooling.  The wrapper comes with a Connection class that
has methods custom built for the unofficial '|' seperated Items or records and the
'Attribute Symbol' seperated attributes or columns 


--------------------------------------------------------------------------------

DEPENDENCIES:

The mvapi.jar is the underlying MVSP provided by TigerLogic.  It is a dependency
for this project and can be dowloaded from their ftp site
ftp://ftp.tigerlogic.com/pub/MVSP/Java/

(it's packaged in the MVSPJavaAPI.zip)

--------------------------------------------------------------------------------

HOW TO BUILD:

1.  Need maven

2.  Uses the assembly plugin to maven to create single jar
http://maven.apache.org/plugins/maven-assembly-plugin/

3.  To build: mvn package


HOW TO USE:

1.  Add from step2 to class path
2.  Call the session manager like described in sample class below:


package com.foo;

import java.sql.ResultSet;
import java.sql.SQLException;
import javax.management.InstanceAlreadyExistsException;
import javax.management.MBeanRegistrationException;
import javax.management.MalformedObjectNameException;
import javax.management.NotCompliantMBeanException;
import org.orphanware.mv.sessionmgr.MVConnection;
import org.orphanware.mv.sessionmgr.MVSessionMgr;


/**

public class MVJDBCProxy {

    
    private MVConnection conn;
    private MVSessionMgr mvSessionMgr;
    
    public MVJDBCProxy() throws InstanceAlreadyExistsException, MBeanRegistrationException,
            NotCompliantMBeanException, MalformedObjectNameException, SQLException{
            


        mvSessionMgr = MVSessionMgr.getInstance();
        mvSessionMgr.setUser("${mv.login}")); //default is MVSP
        mvSessionMgr.setPassword("${mv.loginpass}"); //default is *blank*
        mvSessionMgr.setAccount("${mv.account}"); //whatever account u want to login to
        mvSessionMgr.setAccountPassword("${mv.accountpass}"); //the account password
        mvSessionMgr.setUrl("${mv.addr}")); //jdbc:mv:mvbase:*.*.*.*:9010
        mvSessionMgr.setPoolsize(5); //any num as long as u have licenses 
        conn = (MVConnection) mvSessionMgr.getConnection();

    }

    
    public ResultSet callMVSub(String subName, String params) throws SQLException,
            Exception {
        
        ResultSet rs = null;
        try {
            
            rs = conn.callMVSub(subName, params);
        
        } catch( Exception e) {
            
        } finally {
        
            conn.close();
        }
        
        return rs;
    }
    
    public ResultSet callMVSubLongWait(String subName, String params, int longWaitTime) throws SQLException,
            Exception {
        
        ResultSet rs = null;
        try {
        
            rs = conn.callMVSub(subName, params, longWaitTime);
        
        } catch( Exception e) {
            
        } finally {
        
            conn.close();
        }
        
        return rs;
    }
}


-------------------------------------------


3.  access data like so:


MVJDBCProxy mvproxy = new MVJDBCProxy();

MVResultSet rs = (MVResultSet) mvproxy.callMVSub("HELLO.WORLD", "param1|param2"); //HELLO.WORLD is just example.  it would have to exist in account and be cataloged



if (rs.getNumRows() == 0) {
renderText("");
return;
}

String[][] rows = new String[rs.getNumRows()][rs.getNumAttributes()];


int i = 0;

do {
logger.debug("row " + i + " has " + rs.getNumAttributes() + " columns: " + rs.getRow(i));
String[] attrbs = new String[rs.getNumAttributes()];
for (int j = 0; j < rows[i].length; j++) {


    attrbs[j] = rs.getAttrString(j);

}

rows[i] = attrbs;
i++;

} while (rs.next());
