Hi Steve,
What is the version of the Virtuoso JDBC Driver (virtjdbc3.jar) being
used ? This can be determine with commands of the form in my case:
~/binsrc/jena$ java -cp "../../libsrc/JDBCDriverType4/
virtjdbc3.jar:." virtuoso.jdbc3.Driver
OpenLink Virtuoso(TM) Driver for JDBC(TM) Version 3.x [Build 3.26]
The error you report indicates you may be using an older version of
the JDBC Driver thus you need to make sure you are using the latest
version, which works for me as follows:
~/binsrc/jena$ /usr/bin/java -classpath "lib/arq.jar:lib/iri.jar:lib/
jena.jar:lib/icu4j_3_4.jar:lib/xercesImpl.jar:lib/commons-
logging-1.1.1.jar:lib/axis.jar:../../libsrc/JDBCDriverType4/
virtjdbc3.jar:./virt_jena.jar:.:virtuoso_driver" VirtuosoSPARQLExample1

I'm trying to run the Jena Provider samples and I'm getting an
error. Any help figuring out why this is failing is appreciated:
Exception in thread "main" com.hp.hpl.jena.shared.JenaException:
Convert results are FAILED.:virtuoso.jdbc3.VirtuosoException:
Virtuoso Communications Link Failure (timeout) : Connection to the

at virtuoso.jena.driver.VirtuosoQueryExecution.execSelect

at VirtuosoSPARQLExample1.main(VirtuosoSPARQLExample1.java:51)
The server logs say:
"Malformed data received from IP [127.0.0.1]: Box length too large.
Disconnecting the client"
Here is what appears to be configured properly:
* Running 5.0.10 virtuoso-javavm-t
* Including the classpath of all the jars included in the jenajars
package
* VirtuosoSPAQRLExampleX.java samples compiled properly
* I can make a connection directly to iSQL: "sql 1111 dba dba"
* The sample uses the default connection string: "jdbc:virtuoso://
localhost:1111"
* I am able to successfully connect with the JDBC sample app:
{virtuoso-source}/binsrc/samples/JDBC/jdk1.3/JDBCDemo
Example:
java -cp "../jar/iri.jar:../jar/icu4j_3_4.jar:../jar/
virtjdbc3.jar:../jar/axis.jar:../jar/xercesImpl.jar:../jar/
jena.jar:../jar/arq.jar:../jar/commons-logging.jar:../jar/
