Xindice / Java problem

[Christian W. Guenther]

Hallo,

please excuse if I violate any group etiquette etc. but I am not very
experienced both regarding the usenet and your group.

I have installed Xindice, integrated into Tomcat, and can use it via the
command line tools provided without problems. Yet when I try to access
the database within a Java program I get the following error:

trying to register database
Exception in thread "main" java.lang.NoCla ssDefFoundError :
org/apache/xmlrpc/XmlRpcException
at
org.apache.xind ice.client.xmld b.xmlrpc.Databa seImpl.getColle ction(DatabaseI mpl.java:354)
at
org.apache.xind ice.client.xmld b.DatabaseImpl. getCollection(D atabaseImpl.jav a:137)
at org.xmldb.api.D atabaseManager. getCollection(U nknown Source)

com.plaengine.r epository.util. XmlDbBootstrap. createCollectio n(XmlDbBootstra p.java:55)
at
com.plaengine.r epository.util. XmlDbBootstrap. main(XmlDbBoots trap.java:87)

The class XmlDbBootstrap uses code from the Xindice Website programming
tutorial which should create a new collection within the standard root
collection 'db'. The relevant piece of code is:

String driver = "org.apache.xin dice.client.xml db.DatabaseImpl ";
Class c = Class.forName(d river);
Database database = (Database)
c.newInstance() ;DatabaseManage r.registerDatab ase(database);
String uri = "xmldb:xind ice://localhost:8080/db";
col = DatabaseManager .getCollection( uri);

The last line is exactly the point where I get the exception / crash and
I simply cannot figure out where the problem is. When I am using the
exact URI from the command line everything works out flawlessly.
Are there any known bugs or pitfalls regarding Xindice or the xml:db
interface, or can you think of anything I have done wrong?
Any help is more than welcome.

Thanks in advance,
Christian

For software versions, I have installed:
OS: Mac OS 10.3 (Panther)
Tomcat 5.0.27
Xindice 1.1b4

If you reply to me directly, please delete the 'NOSPAM.' from my adress.

Learn to interprete Error Messages ;o) Thats the only importend issue.

java.lang.NoCla ssDefFoundError => The Classloader was not able to find
one required class. In detail: he was not able to find
org.apache.xmlr pc.XmlRpcExcept ion

So just add the required class to the classpath. In most cases such
classes will be stored inside jar files. It is necessary to add such jar
files explicitly.

for example:
-cp ./xmlrpc.jar
