ClassNotResolvedException: Class "org.hsqldb.jdbcDriver"
After struggling for several days, I arrived here...desperately

org.datanucleus.exceptions.ClassNotResolvedException: Class "org.hsqldb.jdbcDriver" was not found in the CLASSPATH

I tried datanucleus 1.1.2, 1.1.3, 1.1.4, all the same.

the code snippet is pretty much the same to what has suggested in the forum.

ClassLoader clrDriver=null;
clrDriver = Platform.getBundle("x").loadClass("org.hsqldb.jdbcDriver").getClassLoader();

props.put("datanucleus.primaryClassLoader", clrDriver);

ClassLoader clrDN=null;

clrDN = Platform.getBundle("org.datanucleus").loadClass("org.datanucleus.jdo.JDOPersistenceManagerFactory").getClassLoader();

pmf = JDOHelper.getPersistenceManagerFactory(props, clrDN);


The exception is very familiar:

Caused by: org.datanucleus.exceptions.ClassNotResolvedException: Class "org.hsqldb.jdbcDriver" was not found in the CLASSPATH. Please check your specification and your CLASSPATH.
at org.datanucleus.JDOClassLoaderResolver.classForName(JDOClassLoaderResolver.java:250)
at org.datanucleus.JDOClassLoaderResolver.classForName(JDOClassLoaderResolver.java:415)
at org.datanucleus.store.rdbms.datasource.DriverManagerDataSource.<init>(DriverManagerDataSource.java:87)
... 53 more


Can anybody please cast me some light?

Many thanks in advance!

Hi, Guido

thanks! but the class was there...

Another thread has the same problem, but the solution is not so clear.

Any other suggestions? Many thanks!

This is what you say and what you can see.
As you can imagine, we have no access to your desktop to check by ourselves, so the only thing we can say is the above.

Re: ClassNotResolvedException: Class "org.hsqldb.jdbcDriver"
Hi,

I followed this article.
http://www.jpox.org/servlet/wiki/pages/viewpage.action?pageId=1179712

it solved the same problem by adding 2 classloaders for jdbc driver and persistencemanagementfactory respectively.

but this didn't work for me...

Bundle-ClassPath:
...
lib\hsqldb.jar,

which is in the right path.

and deployed other datanucleus bundles in plugins

Require-Bundle: org.eclipse.osgi.services;bundle-version="3.1.200",
org.eclipse.core.runtime;bundle-version="3.4.0",
org.datanucleus;bundle-version="1.1.4",
org.datanucleus.enhancer;bundle-version="1.1.4",
org.datanucleus.store.rdbms;bundle-version="1.1.4"

Thanks again!

best,
fey
