I'm rather new to velocity, but find it would save me a
ton of work. I've tryied it using some templates to generate stored
procedures and found it quite easy. Now I would like to try and us it in
an
application with rather small, in-memory templates. The problem is, I can
not
seem to get this to work. Here is a simple example:
What I'm trying to do, is pass the template as the name, then create a new
resource loader to just return the name as a byte stream.
Obviously, this is not correct.
String c ="create table $schemaName.$tablename ( "
+ " #foreach ($dbColumn in $columnList) "
+ " $dbColumn.columnName $dbColumn.SQLDef, "
+ " #end "
+ " purge_date datestamp )";
Velocity.init(); // don't hurt
Template temp =new Template();
StringResourceLoader sl = new StringResourceLoader();
StringWriter sw = new StringWriter();
VelocityContext context = new VelocityContext();
context.put("schemaName",schemaName);
context.put("tablename",getTbName());
context.put("columnList",v);
temp.setResourceLoader(sl);
temp.setName(c);
temp.process();
temp.merge(context,sw);
// try this
System.out.println(sw.toString());
My String Resource Loader looks
public InputStream getResourceStream(String arg0)
throws ResourceNotFoundException
{
ByteArrayInputStream is = new ByteArrayInputStream(arg0.getBytes());
return is;
}
thanks
