Load variables like deploy xml file

[dannygaviria]

Hi,

I access a database every transaction for consulting product status and others, i want to load in  variable (array, object, ??) this information when the Q2 begin, or create an special xml like deploy files.

<data>

<products>

<item><max>10</max><min>5</min> </item>

<item><max>15</max><min>10</min> </item>

</products>

</data>

1- thats is pposible?

2- Exists some option.

3- How to create the variable, and how to persists into the transaction participants.

My initial idea is create an xml and load into arrray. and when i need the data search in the array.

Thanks.

You can use an ‘xml-config’ element.

The ‘xml-config’ element is handled by org.jpos.q2.qbean.QXmlConfig that basically stores a reference to itself in the NameRegistrar.

Then you get it like this:

        Element cfg = QXmlConfig.getConfiguration (CONFIG_NAME, CONFIG_TIMEOUT);

Element is an org.jdom.Element.

Here is a sample config we use in QI (Q2 UI we are working on):

<xml-config name="QI" logger="Q2">
  <title>jPOS QI</title>
  <theme>jpos</theme>
  <locale>en-US</locale>
  <menubar>
    <menu name="System" icon="COG" style="icon-cog">
      <menu name="About"  action="about" />
      <menu name="Memory 1">
        <menu name="Sub Memory 1"  action="memory" />
        <menu name="Sub Memory 2" perm="system">
          <menu name="Sub Sub Item"  action="memory" icon="COG" perm="sysconfig.read" />
        </menu>
      </menu>
      <separator />
      <menu name="Memory 2"  action="memory" />
      <menu name="Memory 3"  action="memory" />
      <menu name="Memory 4"  action="memory" />
    </menu>
    <menu name="Options">
      <menuitem name="Quit"   action="exit" />
    </menu>
  </menubar>

  <sidebar>
    <section name="System" />
    <option name="About" action="about" />
    <option name="Memory" action="memory" />
    <option name="SysConfig" action="sysconfig" />
    <option name="Users" action="users" />
  </sidebar>

  <view route="/home" class="org.jpos.qi.DefaultView" perm="*" />
  <view route="/about"  class="org.jpos.qi.system.AboutView" perm="system" />
  <view route="/memory" class="org.jpos.qi.system.MemoryUsageView" perm="system" />
  <view route="/sysconfig" class="org.jpos.qi.sysconfig.SysConfigView" perm="system" />
  <view route="/users" class="org.jpos.qi.eeuser.UsersView" perm="system" />
</xml-config>

​

​Hope this helps.

​

​Our web application access a 00_qi.xml deploy element and then goes over the XML config.
