php-java-bridge-users Mailing List for PHP/Java Bridge

Hi,

like other containers (EJB for example), the PHP/Java Bridge container
terminates the current transaction if a java.lang.RuntimeException or
java.lang.Error crosses the container boundary. However, it does not
terminate it immediately, to give you a chance to clear the error condition
before the PHP script terminates.

Please see
http://php-java-bridge.sourceforge.net/pjb/docs/php-api/JavaBridge/_JavaProxy.inc.html#functionjava_last_exception_clear
for details.

Please see our FAQ entry "Why doesn't the bridge throw a
java.lang.RuntimeException or Error as a PHP JavaException by default?"


> [[o:Response$
> UndeclaredThrowableErrorMarker]]->execSelect. Cause:
> java.lang.NoSuchMethodException: execSelect(). Candidates: [] VM:

please take a look at the error message again; your code:

$query = Java("com.hp.hpl.jena.query.QueryFactory")->create($sparqlString);
//---OK.

has thrown a java.lang.Error or java.lang.RuntimeException, which is
reported as a PHP warning. In the next step you ignore the warning, take the
RuntimeException and try to invoke execSelect() on it, which fails, of
course.

If you want java.lang.Error and java.lang.RuntimeException to fail fast,
define("JAVA_PREFER_VALUES", true) before including Java.inc.

Hi,

I have a question.

Can I do something like this:

ResultSet rs = QueryExecutionFactory.create(q, m).execSelect(); 

(where ResultSet rs is a java interface, QueryExecutionFactory.create(q,m) returns a java interface and execSelect() function is declared in this interface).

with PHP/Java Bridge?

In Java I can.

How can I do that?

I have tried this:

$query = Java("com.hp.hpl.jena.query.QueryFactory")->create($sparqlString); //---OK.
$rs = Java("com.hp.hpl.jena.query.QueryExecutionFactory")->create($query, $modelD2RQ)->execSelect(); //---crash here

but it replies:

java stack trace: java.lang.Exception: Invoke failed:
[[o:Response$UndeclaredThrowableErrorMarker]]->execSelect. Cause:
java.lang.NoSuchMethodException: execSelect(). Candidates: [] VM:

Thanks in advance.
