how to run solr in windows & Tomcat5

I input all the source code in winxp sp2 & tomcat 5 in
jBuilder . when I
debug the application always throw Exception like :
org.apache.solr.core.SolrException: Error loading class
'solr.StandardFilterFactory'...
Caused by: java.lang.ClassNotFoundException: ...
such as ort.apache.solr.schema.* all throw this Exception ;I
think those
codes :
public static Class findClass(String cname, String...
subpackages) {
    ClassLoader loader =
Thread.currentThread().getContextClassLoader();
    if (subpackages.length==0) subpackages = packages;

    // first try cname == full name
    try {
      return Class.forName(cname, true, loader);
    } catch (ClassNotFoundException e) {
      String newName=cname;
      if (newName.startsWith(project)) {
        newName = cname.substring(project.length()+1);
      }
      for (String subpackage : subpackages) {
        try {
          String name = base + '.' + subpackage + newName;
          log.finest("Trying class name " +
name);
          return Class.forName(name, true, loader);
        } catch (ClassNotFoundException e1) {
          // ignore... assume first exception is best.
        }
      }

      throw new SolrException(500, "Error loading
class '" + cname + "'", e,
false);
    }
in org.apache.solr.core.Config class cause the exception;
who can tell me why;Reason is A:cofig file not load?B:tomcat
classloader
cause the exception?C:maybe some liberary not
import?D:OTHERS?... 
Thanks!

solr.StandardFilterFactory and any solr.* class names you
might see in a
config file are just short alias names for full classnames
in the
org.apache.solr.*.* packages.  the method you mention that
throws this
exception is responsible for resolving those names in a set
of packages
passed in by the caller based on what it's expecting to
find.  It's
default behavior is to assume the package name in the config
is the full
real class name, if it can't find that then check the known
packages, and
if it still can't find it then throw an exception refering
to the
*orriginal* name.

the fact that you are seeing this exception means that it
can't load any
version of the class, including the fully qualified name
org.apache.solr.analysis.StandardFilterFactory.

YOu said you are running tomcat/solr inside of jBuilder? ..
are there
perhaps some jBuilder settings related to classpath context
you could try
twiddling? ... i don't personally have a lot of experience
running
applications inside of IDEs (particularaly applications like
tomcat, which
themselves manage classpaths for other code.

As i said: i don't relaly know a lot about running
applications from
within an IDE --  and for that matter, i don't really know
a lot about
classloaders in general -- but the error you are getting
indicates that
when jBuilder tries to run tomcat, which tries to load Solr
it's not
finding those classes.

Have you tried running tomcat with the precompiled solr.war
*not* in
jBUilder ... just as a standalone java application?  if that
works, then
there is probably something wrong with your classpath
configuration in
jBuilder.

...did you look at the tomcat logs directory to see if there
were any
errors when the server tried to start itself?

I'm guessing the problem is that on startup it couldn't
find your
solrconfig.xml file (or your schema.xml) so the core classes
couldn't be
initialized, so when you tried to load the page those
classes can't be
found.  Where do you have your config files?  is there a
"solr/" directory
in the current working directory when you start the server,
or are you
setting the solr.solr.home system property, or using the
recently added
(but not yet well documented) jndi options for specifying
solr.home?


using the following steps, i was able to start up solr
server using the
example configs (copied into my current working directory)
and access it
at http://localhost:80
80/solr/admin/ ...

laptop:~/tmp> mkdir solr-tomcat
laptop:~/tmp> cd solr-tomcat/

...if it can't find your configs, you'll see some really
obvious

like this...
