Running out of pooled connections

Question

i have web application developed with jsp/servlets and mysql. i use JNDI datasource connection pooling. i have the following element defined in my server.xml file:
<Resource name="jdbc/JSNDB" auth="Container" type="javax.sql.DataSource"
          maxActive="100" maxIdle="30" maxWait="10000"
               removeAbandoned="true" removeAbandonedTimeout="60"
logAbandoned="false"
          username="root" password="pn2072"
driverClassName="com.mysql.jdbc.Driver"
     url="jdbc:mysql://localhost:3306/globe?autoReconnect=true"/>
my site is highly dependent on the databse for content and makes extensive use of db conections. only after a few clicks, my application cannot get any more connections from the pool. when i check the mysql server, i see that after 100 connections are created, they are never released even though i close every resultset, statement and connection immediately after i use them.
can any one please help.
many thanks

hi
this is the method from which I get connections from the pool:
public static Connection getConnection() {
     DataSource ds=null;
     try {
     Context ctx = new InitialContext();
     if(ctx == null ) throw new Exception("Boom - No Context");
     ds = (DataSource)ctx.lookup("java:comp/env/jdbc/JSNDB");
               return ds.getConnection();
     } catch(Exception e) {
     e.printStackTrace();
     return null;
and this is how i close my connections (in every method that gets a connection):
finally
               try{
rst.xlose();
                    stmt.close();
                    conn.close();
               catch(SQLException e){}
          }
