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.NoClassDefFoundError:
org/apache/xmlrpc/XmlRpcException
at
org.apache.xindice.client.xmldb.xmlrpc.DatabaseImpl.getCollection(DatabaseImpl.java:354) at org.apache.xindice.client.xmldb.DatabaseImpl.getCollection(DatabaseImpl.java:137) at org.xmldb.api.DatabaseManager.getCollection(Unknown Source) at org.xmldb.api.DatabaseManager.getCollection(Unknown Source) at com.plaengine.repository.util.XmlDbBootstrap.createCollection(XmlDbBootstrap.java:55) at com.plaengine.repository.util.XmlDbBootstrap.main(XmlDbBootstrap.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.xindice.client.xmldb.DatabaseImpl"; Class c = Class.forName(driver); Database database = (Database) c.newInstance;DatabaseManager.registerDatabase(database); String uri = "xmldb:xindice://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.NoClassDefFoundError => The Classloader was not able to find one required class. In detail: he was not able to find org.apache.xmlrpc.XmlRpcException

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
