Hello,
My name is Brian and I'm the founder of http://dreamer.me. We're a non-profit search engine - money from our search results go to various charities and causes as chosen by our users. In 2009 Google made a profit of over $4Billion mostly because they were the market for internet advertising. Our goal is to create a *open source* and non-profit alternative to google and instead of spending our money trying to build a better iphone, we will be using it to solve the real problems of the world (the environment,health, hunger, and education)
Since we use jboss as our webserver I thought this would be a good place to start looking for some help
I have a few questions
1. How does one start a open source project?
2. More importantly, is there anyone you know who would like to be involved?
3. Is there anyone you know who would like to LEAD the project (and would be capable of doing so)?
(http://dreamer.me is already up and running, we use Yahoo BOSS to generate our search results, it was developed with JAVA servlets/jsp, MySQL, JBOSS, and jQuery)
If you'd like to email me directly I can be reached at http://community.jboss.org/mailto:brian@dreamer.me

Thanks to the replies from Denis and Max, I tried a few more things and got it to work now.
The issue was with the hibernate.reveng.xml file.
Based on what the wizard created, I had just this in in the reveng.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering PUBLIC "-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >
<hibernate-reverse-engineering>
<table-filter match-schema="maintenance" match-name=".*"/>
<table-filter match-schema="consultant_db" match-name=".*"/>
</hibernate-reverse-engineering>
I also changed the 'match-schema' attribute to 'match-catalog', but that didn't help.
However, when I changed it to the following, it worked fine:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering PUBLIC "-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >
<hibernate-reverse-engineering>
<schema-selection match-catalog="maintenance" />
<schema-selection match-catalog="consultant_db" />
</hibernate-reverse-engineering>
In other words, just using 'table-filter' doesn't make it look at different catalogs/ databases in MySQL, but the 'schema-selection' element does.
I think this is quite acceptable for how it works.
However, the Hibernate reverse engineering editor can perhaps be improved:
- How can we get multiple schemas to show up in the wizard? It looks like the wizard looks at the hibernate.connection.url property in the hibernate-console.properties file. However, when I leave out the name of the database (e.g. jdbc:mysql://localhost:3306) without the database, the wizard does not return any tables.
- The wizard could have an extra tab at the bottom where you can select the schemas/ catalogs you want, effectively creating the <schema-selection ...> tags
Thank you!

[JBoss Web Services] New message: "Re: Error doing multiple calls to web service"

My operation are synchronous.
I wait the result from call1 before submitting call2 (I use data from call1 in call2 and call3).
To test I use a command line java application with only one class with a main (no other threads).
The network traffic is encrypted (https) so it is not possibile to watch inside packet, but the flow is visible using wireshark (I attached a dump of the packets summary; you can see that call2 send the request, but receive a disconnect form the server after 80 seconds).
I enabled log4j at TRACE level to provide you more infomation, but I faced a new strange behaviour: the error doesn't appear always as before, but only very few times and not on call2, but on call3 (I attached a log with an error on call3).

I was having the same issue. I believe that the reason was that I was calling a listener on the wrong state event:
<state g="137,123,150,52" name="Generate Visibilities">
<on event="start">
<event-listener class="com.boeing.ids.sogs.gmpwf.listeners.VisibilityListener" />
</on>
<transition g="-143,-10" name="to Check Out Time Segment" to="Check Out Time Segment"/>
<transition name="to cancel" to="cancel" g="-48,-18"/>
<transition name="to error" to="error" g="-42,-18"/>
</state>
Within the listener, I was doing some external work then calling the executionService.signalExecutionById()method. I think the reason it was failing was because I was calling this method within the state's start event. In jBPM, you can't trigger a transition to another state until the (current) state execution stops. When I changed the jpdl code to call the listener on the state's end event, the exception went away:
<state g="137,123,150,52" name="Generate Visibilities">
<on event="end">
<event-listener class="com.boeing.ids.sogs.gmpwf.listeners.VisibilityListener" />
</on>
<transition g="-143,-10" name="to Check Out Time Segment" to="Check Out Time Segment"/>
<transition name="to cancel" to="cancel" g="-48,-18"/>
<transition name="to error" to="error" g="-42,-18"/>
</state>
Hope this helps.
