I'm following the sample and I got the exception as follow when i try to invoke ./wso2cep-samples.sh -sn 0504 command in terminal. What can i do to get mu app up and run?
ERROR
{org.wso2.carbon.event.processor.core.internal.storm.StormTopologyManager}
- TopologySubmitterJob:116, Runtime Exception connecting to storm when trying to check whether topology 'StatExecutionPlan[-1234]' exist
I found the answer by my self. I set false in the <parameter name="AvoidInitiation">false</parameter> tag. in conf/axiss/axis2.xml. Then app is work fine.

I am running a gremlin-server, and using restful api to query it. But I'm confused with this error below :
{"message":"Error encountered evaluating script: g.V().next()"}
but it is such a simple script.
for other script like "100-1" and "g", the query result is just OK. I have checked lots times for spelling and character. And I also have checked the gremlin-server logs, but there was no related records. So I ask for your help, Thanks!
You would run into that error if you don't have any data in the graph because it is an unchecked traversal. You should try a query like:
if (g.V().hasNext()) { g.V().next() }
If you're using Apache TinkerPop 3.1.2 or later, you would have seen a more informative stack trace in the Gremlin Server logs:
[WARN] HttpGremlinEndpointHandler - Invalid request - responding with 500 Internal Server Error and Error encountered evaluating script: g.V().next()
org.apache.tinkerpop.gremlin.process.traversal.util.FastNoSuchElementException
I've been using my SQL database initialization script for a while, but it seems that recently the database crashes in the middle of the execution and I don't know why, but here's some details:
I am running OrientDB on Ubuntu 14 Trusty x64 (via Vagrant)
It always seems to crash while the script attempts to create a UNIQUE_HASH_INDEX, but doesn't always crash at the same UNIQUE_HASH_INDEX instruction
The script creates a lot of vertices and edges, but for example, it will crash here (see line with UNIQUE_HASH_INDEX):
CREATE CLASS Channel EXTENDS V;
CREATE PROPERTY Channel.version LONG;
CREATE PROPERTY Channel.channelId STRING;
CREATE INDEX Channel.uq_channelId ON Channel(channelId) UNIQUE_HASH_INDEX;
The database crashes entirely with the following error:
Creating index... Error:
com.orientechnologies.orient.core.exception.OStorageException: Error
on executing command: sql.create INDEX Channel.uq_channelId ON
Channel(channelId) UNIQUE_HASH_INDEX
Error: java.io.EOFException
Looking at the log files, the only hint I get are the last two lines:
2016-01-14 17:17:05:437 INFO Received signal: SIGTERM [OSignalHandler]
2016-01-14 17:17:05:454 INFO Received signal: SIGTERM [OSignalHandler]
How can I resolve this issue, or at least get better hints as to what is making the database crash?
I also test with OrientDB 2.1.6, as I was running the older version initially. Same problem.
Sorry, false alarm -- this is a Vagrant issue, not an OrientDB issue. Running the exact same script on a 32bit instance instead of 64bit solved my problem, and installing the same script on a real 64bit server also works.
Was trying to implement the triggers in Cassandra.
Have been trying to use the available Cassandra help: https://github.com/hmsonline/cassandra-triggers
Porting it on the latest version 1.2.3, and following the GettingStarted instruction.
when i tried to set the value for the trigger, inserting the data to fire the log, and checked the logs, following is the error which i received
java.lang.AssertionError

But we test it works fine at older version(ex: 1.1.2)
So is this a configuration problem, or the Thrift API implementation has been changed?
thanks
I'm trying to learn to work with bpel. I choose Eclipse Bpel Designer and apache ode (on a tomcat server) in order to experiment. The process I tried to model was a loan process. It has 3 services: a creditRate service (written in eclipse bpel designer and deployed befo-hand an tested that it works), a currency converter service, and the main orchestration process. While I had no errors on deployment when testing the web service from eclipse following errors occur:
ERROR [ExternalService] Error sending message to Axis2 for ODE mex

Can someone help me out with a solution? I have searched for some solution but have not found one that works. It may be that due to my poor knowledge I am not searching right or not doing something right. Because this description may be confusing I have attached my solution because I believe they will tell more of what I'm trying to do and how wrong I am doing it. http://www.mediafire.com/?9bjgt44spln1zwr
Thank-you in advance
EDIT: after doing an iterative approach (as sugested in the first answer) it seems that the external conversion service was not responding from ode. This is strange because the service worked from the browser and no error was reported when deplying. Again because of my poor knowledge I believe code speaks better than my phrasing. I have made an eclipse project just with the external currency convertor. Any help / guidance is heartly appreciated. Thank you in advance. http://www.mediafire.com/?56csca1qgt5ka9a
Your CreditRating process works fine, the error lies in the CreditBuletin process. When I test this one with soapUI, I get a selectionFailure. This error in BPEL tells you that something is wrong with a from or to in your process.
To outline the problem here is a very simplified version of the activities of your CreditBuletin process, reduced to just the initial receive, the final reply and one of your assign activities inbetween. You can paste this into the main sequence of your process to reproduce the problem.
<bpel:receive name="receiveInput" partnerLink="clientInput" operation="getLoan" portType="tns:CreditBuletinPT" variable="receiveInput" createInstance="yes"></bpel:receive>
<bpel:assign validate="no" name="AssignFinal">
<bpel:copy>
<bpel:from>
<bpel:literal>
<tns:SumaRON xmlns:tns="CreditBuletinNamespace" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<output>0</output>
</tns:SumaRON>
</bpel:literal>
</bpel:from>
<bpel:to variable="outputResult" part="parameters"></bpel:to>
</bpel:copy>
<bpel:copy>
<bpel:from>
<![CDATA[$loanWithInterest * bpel:getVariableData('CurrencyRateInputResponse','parameters','ConversionRateResult')]]>
</bpel:from>
<bpel:to part="parameters" variable="outputResult">
<bpel:query queryLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0">
<![CDATA[output]]>
</bpel:query>
</bpel:to>
</bpel:copy>
</bpel:assign>
<bpel:reply name="outputResult" partnerLink="clientInput" operation="getLoan" portType="tns:CreditBuletinPT" variable="outputResult"></bpel:reply>
You are trying to assign the same variable twice, first with a default initialization. This doesn't make much sense, but for some reason the BPEL editor generates these initializations on default. You get a correct reply, if you change the from statement in the second copy to something else, for instance
<![CDATA[bpel:getVariableData('receiveInput','parameters','suma')]]>
So, your problem(s) come(s) from your from statements, most likely the ones that use the getVariableData() function. Now, I don't want to repair all expressions in your process (because there are many and that is your task), but I suggest to have a look at all of them. Start with a minimal working process, such as the one above with the from exchanged and do incremental updates of functionality while testing each increment. That way, you will eventually end up with something that works.
I'm working on an EJB3 MDB that listen to a MQ queue in a distant server.
All is working fine (MDB triggered when a message is put into the listenned queue) except the treatment done by the MDB. For information, i use WMQ resource adapter to map the queue.
Into the method 'onMessage' of the MDB, i try to cast the given message into the class 'com.ibm.jms.JMSBytesMessage', but i get a strange error message.
The code is the following one (simple for the example):
public void onMessage(Message theMessage) {
((JMSBytesMessage) theMessage).readBytes(myBytes);
}
And the exception message:
Exception while reading input request: com.ibm.jms.JMSBytesMessage incompatible with com.ibm.jms.JMSBytesMessage
Ok, the message received should be (and is) type 'com.ibm.jms.JMSBytesMessage', so why the application doesn't work ? Should it be possible that my JBoss server already use another version of the library 'com.ibm.mqjms.jar' (including the JMSBytesMessage class) and cause this kind of error ?
ps: i've deployed the application on a JBoss server version 4.2.3 under linux system.
I've already make the application work on my local machine with same version of JBoss server but under window system (same configuration, same libraries, etc.)
Does someone have an idea about the reason of such error ?
Thanks in advance for any help.
Regards,
EDIT: SOLUTION: cast with javax.jms.BytesMessage instead of com.ibm.jms.JMSBytesMessage
Might as well reproduce my comment as answer:
Don't cast to the MQ-specific com.ibm.jms.JMSBytesMessage, cast to the JMS-standard javax.jms.BytesMessage. Coupling your code to the implementation-specific types is counter to what JMS tries to achieve.
