i write this build.xml but dont work ,
it cannot find the jdbc driver
maybe i have defined the class path wrongly
what is the problem ?



build.xml file :

check to see if the classpath is actually correct, e.g contains the relevant jar and that the driver class you are referring to is in it.

you should be able to see the resulting classpath by running ant with -verbose or -debug flag.

hello to everybody and special thanks for max

i use java code to run ant tasks
i write a code that use hibernate tools in it and i must use the ant api to run hibernate tools task

i write a sample code to generate hbmxml files , this code works correctly when i give classpath in my module settings like this : "java.exe -classpath ... "
but i must configure this path in ant not in my module setting

this is my sample code :
HibernateToolTask t = new HibernateToolTask();
Project project = new Project();
project.setBaseDir(new File("D:/DevDesk/hibernateToolsTest/src"));
Path p = new Path(project);

p.add(new Path(project, "C:/Program Files/Microsoft SQL Server 2000 Driver for JDBC/lib/msbase.jar"));
p.add(new Path(project, "C:/Program Files/Microsoft SQL Server 2000 Driver for JDBC/lib/mssqlserver.jar"));
p.add(new Path(project, "C:/Program Files/Microsoft SQL Server 2000 Driver for JDBC/lib/msutil.jar"));

t.setClasspath(p);

JDBCConfigurationTask ct = t.createJDBCConfiguration();
ct.setProject(project);
ct.setConfigurationFile(new File("D:/DevDesk/hibernateToolsTest/src/hibernate.cfg.xml"));
ct.setPackageName("aria.roohi");

Configuration cfg = ct.getConfiguration();
t.setDestDir(new File("D:/DevDesk/hibernateToolsTest/src/generated"));
t.createHbm2HbmXml();
AntRunner ar = new AntRunner();
ar.runTask(t, "D:/DevDesk/hibernateToolsTest/src");



when i run it , this exception occure :

the driver has to be in the classpath of the <taskdef>; you will have to mimick that in your programmatic api access.

hello
when i specify classpath by java.exe -classpath and create a new instance of HibernateToolTask , the hibernateToolTask that loaded by java class loader wants to load jdbcDriver by his classloader and and this class loader hasnt the path of jdbcDriver ,,,
i use reflection to resolve this problem ,,


try {
