"XMLCommand.initialize failed: java.lang.NullPointerException" when using dataset-proxy in a workflow databroker - aviarc
I'm creating a workflow databroker, and in the pre-workflow I am using a dataset-proxy to iterate over the populate-dataset. However I get the following error when I compile:
XMLCommand.initialize failed: java.lang.NullPointerException

I get exactly the same error even when I use the code example straight out of the documentation (com.aviarc.dataset:1.1.0):
<workflow xmlns:ds="urn:aviarc:xmlcommand:com.aviarc.dataset">
<ds:dataset-proxy dataset="ds" proxyname="dsproxy">
<set-current-row dataset="dsproxy" position="2" />
<set-field field="dsproxy.email" value="test#test.com" />
</ds:dataset-proxy>
</workflow>
Turns out that the documentation is wrong, as proxyname is not a valid attribute on dataset-proxy. I didn't see it at first (because of the huge stack trace) but I was also getting this warning:
Unknown attribute 'proxyname'
The correct attribute is name, not proxyname. Changing this resolved the error.

file_get_html() not working for the only webpage
I want to call a simple DOM file
I tested with another links and it works, but with this url it's not working.
My code is:
$bnadatos = file_get_html("http://www.rofex.com.ar/cem/FyO.aspx");
foreach($bnadatos->find('[#id="ctl00_ContentPlaceHolder1_gvFyO"]') as $i){
echo "datos:";
echo $i->innertext;
}
Response is a blank page.
What's wrong?
i solved with
$arrContextOptions=array(
"ssl"=>array(
"verify_peer"=>false,
"verify_peer_name"=>false,
),
);
$response = file_get_html("https://www.rofex.com.ar/cem/FyO.aspx", false, stream_context_create($arrContextOptions));
foreach($response->find('[#id="ctl00_gvwDDF"]/tbody/tr[2]/td[2]') as $i){
echo $i->innertext;
}
thank you #maio290 for light my road
This is just a guess, but do you have your error reporting on?
Out of the box, this is not working with the simple-html-dom library:
Warning: file_get_contents(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed in /var/www/html/dom.php on line 83
Warning: file_get_contents(): Failed to enable crypto in /var/www/html/dom.php on line 83
Warning: file_get_contents(http://www.rofex.com.ar/cem/FyO.aspx): failed to open stream: operation failed in /var/www/html/dom.php on line 83
Fatal error: Call to a member function find() on boolean in /var/www/html/test.php on line 11
A fix for this can be found here - with that in place, I still get a blank page, which is due to a wrong answer (301 Moved Permanently) - for this to fix, you need to modify
'follow_location' => false
to
'follow_location' => true
so, now we get the proper site content - you can modify the selector to $html->find('#ctl00_ContentPlaceHolder1_gvFyO'); this will find all element which id=ctl00_ContentPlaceHolder1_gvFyO - see the documentation as reference.

how do i declare a dbms output variable on plsql?
I keep getting this error when trying to compile
[Error] PLS-00201 (159: 25): PLS-00201: identifier 'DMBS_UTILITY.FORMAT_ERROR_BACKTRACE' must be declared
Here's the faulty code:
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE('STUDENT:'||V_STUDENT||
'Error Occured: '||SQLERRM ||CHR(10)||'['||
DMBS_UTILITY.FORMAT_ERROR_BACKTRACE||']');
...
As Gurwinder stated, you just have a typo in your code (DMBS_UTILITY instead of DBMS_UTILITY):
Try this:
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE('STUDENT:'||V_STUDENT||
'Error Occured: '||SQLERRM ||CHR(10)||'['||
DBMS_UTILITY.FORMAT_ERROR_BACKTRACE||']');

How to understand this Riak stacktrace?
Can anyone help me solve this problem, I have the stacktrace of the problem, but can't understand what the trace actually means.
The error occurs when I try to retrieve all data from a bucket, in a Riak Database. And I am using java-riak-client library as the ORM. I can figure out that its a MapReduce problem, but other than that.....
Here below is the actual stacktrace, I actually could not figure out what error is it pointing to,
and I tried to find out the record its displaying in error.
#Update: Yes the record is there, when i CURL

The stack trace is telling us that there was a case clause exception at line 180 of the fie riak_kv_wm_mapred.erl The clause at that line is handling the responses for the pipe processing the map phase, which appears to be returning the error preflist_exhausted, which is not explicitly handled by the case statement. That error usually indicates that one or more vnodes were overloaded or otherwise unavailable, and fallbacks had not yet started to take over their workload. The affected partition was 913438523331814323877303020447676887284957839360, the console.log and error.log may have further details about what happened.
Pointer.new(:uint) not converting to proper type for CoreMIDI (RubyMotion)
I'm trying to use CoreMIDI in a RubyMotion project. Here's a simple example of the code:
clientName = "Client"
clientRef = Pointer.new(:uint)
MIDIClientCreate( clientName, nil, nil, clientRef )
See more detailed code and backtrace in the following gist: https://gist.github.com/4299810
That code results in the following error:
(main)> 2012-12-15 14:43:27.410 core-midi-test[42560:c07]
app_delegate.rb:5:in application:didFinishLaunchingWithOptions:':
expected instance of Pointer of type^{OpaqueMIDIClient}', got I'
(TypeError) 2012-12-15 14:43:27.412 core-midi-test[42560:c07] ***
Terminating app due to uncaught exception 'TypeError', reason:
'app_delegate.rb:5:inapplication:didFinishLaunchingWithOptions:':
expected instance of Pointer of type ^{OpaqueMIDIClient}', gotI'
(TypeError)'
The error is apparently with the fourth argument to MIDIClientCreate. The docs for MIDIClientCreate show:
OSStatus MIDIClientCreate (
CFStringRef name,
MIDINotifyProc notifyProc,
void *notifyRefCon,
MIDIClientRef *outClient
);
MIDIClientRef derives from MIDIObjectRef which is defined as a UInt32, so I'm fairly certain that Pointer.new(:uint) is the correct type to use with RubyMotion.
Here is the pertinent portion of the CoreMIDI.bridgesupport file that RubyMotion is using:
<function name='MIDIClientCreate'>
<arg name='name' type='^{__CFString=}' declared_type='CFStringRef'/>
<arg name='notifyProc' function_pointer='true' type='^?' declared_type='MIDINotifyProc'>
<arg type='^{MIDINotification=iI}' declared_type='MIDINotification*' const='true'/>
<arg type='^v' declared_type='void*'/>
<retval type='v' declared_type='void'/>
</arg>
<arg name='notifyRefCon' type='^v' declared_type='void*'/>
<arg name='outClient' type='^^{OpaqueMIDIClient}' declared_type='MIDIClientRef*'/>
<retval type='l' declared_type='OSStatus'/>
</function>
As far as I can tell, the bridgesupport definition should include the necessary plumbing to make the proper conversion. But it's of course, not working.
Is there something wrong with my code or is there something wrong the CoreMIDI.bridgesupport file included with RubyMotion?
I found out by reading the documentation for MacRuby that one can explicitly pass the desired pointer type to the Pointer constructor like so: clientName = "Client" clientRef = Pointer.new(MIDIClientRef.type) MIDIClientCreate( clientName, nil, nil, clientRef ) portName = "Output" outport = Pointer.new(MIDIPortRef.type) MIDIOutputPortCreate( clientRef[0], portName, outport )
