1. Re: how to load extra lib to jboss
adrian.brock Oct 30, 2003 10:16 AM (in response to julian_hu)Did you reboot server, server/all/lib is not hotdeployed.
Show the full stacktrace and the context under which the
classloading occurs.

adrian.brock Oct 30, 2003 6:14 PM (in response to julian_hu)What is doGetData doing?
I doubt it is throwing a NoClassDefFoundError at line 49

4. Re: how to load extra lib to jboss
julian_hu Oct 31, 2003 3:27 AM (in response to julian_hu)here is the code of doGetData
public RowSet doGetData(String sql){
Connection conn=null;
ResultSet rs;
CachedRowSet crs;
CachedRowSet result;
try{
Hashtable env=new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "jnp://127.0.0.1:1099");
//env.put("java.naming.factory.url.pkgs","org.jboss.naming rg.jnp.interfaces");
InitialContext jndiCntx = new InitialContext(env);
DataSource ds=(DataSource)jndiCntx.lookup("java:/MySqlDS");
conn=ds.getConnection();
Statement st=conn.createStatement();
rs=st.executeQuery("Select * from sm_opuser");
crs=new CachedRowSet();
crs.populate(rs);
crs.setTableName(sql);
rs.close();
st.close();
result=crs;
}catch(Exception e){
e.printStackTrace();
result=null;
}
return result;

5. Re: how to load extra lib to jboss
adrian.brock Oct 31, 2003 6:24 AM (in response to julian_hu)I'd be very suprised if that code works.
The java:/ namespace is inaccessible if you
specify a ProviderUrl
Use new InitialContext()

6. Re: how to load extra lib to jboss
julian_hu Oct 31, 2003 7:17 AM (in response to julian_hu)i found this code in this Forum..
Any way,,can you give a right example,how to use CachedRowSet get data from mysql in Session bean in Jboss,thanks a lot. -
7. Re: how to load extra lib to jboss
adrian.brock Oct 31, 2003 7:21 AM (in response to julian_hu)I've never used it.
Are you sure it doesn't require a jdbc3 compliant driver?
You might have more luck if you asked your question
in the persistence forum.
I was commenting on your use of jndi.

Adrian
