| |
| <P>Basically, openejb.base is the source for 100% of all configuration information and third party config files (log4j, castor, instantdb, whatever). This includes finding where the, possibly many, <Deployment> entries in the openejb.conf point. The openejb.home is where the code loading OpenEJB will look for all the OpenEJB libraries. Usually openejb.base is not explicitly set and defaults to the value of openejb.home, so many people are used to only dealing with openejb.home.</P> |
| |
| <P>The point of having and openejb.base and openejb.home was basically to allow several independently configured instances of OpenEJB running on a system (perhaps embedded in Swing apps, in Tomcat, running as a standalone Server, or even in Groovy as Mr. Strachan did!) but without the need to copy all the OpenEJB system libraries everywhere.</P> |
| |

| <P>To include a single jar by name, just declare a 'Deployments' element with a 'jar' attribute pointing to the jar file on the file system.</P> |

| <P>The last element in the example uses a relative path to point to the ejb jar. This path will be resolved relative to the openejb.base property. So, for example, of the value of openejb.base was 'c:\timeapp\' then OpenEJB would look for the jar 'c:\timeapp\timeTrack.jar'. See the <A href="configuration.html" title="Configuration">Configuration</A> guide for more details.</P> |
| |
| <H3><A name="ManualdelUsario-Adirectoryofjars"></A>A directory of jars</H3> |
| |
| <P>To point to a directory that contains several jar files that OpenEJB should load, simply declare a 'Deployments' element with a 'dir' attribute pointing to the directory containing the jar files.</P> |

| </DIV></DIV> |
| |
| <P>The directories listed will be searched for jars containing 'META-INF/ejb-jar.xml' files and will be added to the list of jars to load if they do. Better said, it's completely save to point to a directory containing a mix of ejbs and regular jar files. OpenEJB will simply skip over jars that do contain the required 'META-INF/ejb-jar.xml' file.</P> |
| |
| <P>The last Deployments element declares a 'beans' directory relative to openejb.base for holding ejb jars. This declaration is simply convention and not required.</P> |

| <H3><A name="ManualdelUsario-Anunpackedjar"></A>An unpacked jar</H3> |
| |
| <P>As of 1.0 beta1, OpenEJB supports unpacked ejb jars. Simply meaning that you don't need to pack your ejb's into a jar file in order to use them in OpenEJB. You still need to follow the ejb jar layout and include an "META-INF/ejb-jar.xml" in the directory that contains your ejbs.</P> |
| |
| <P>For example, if you have a directory structure like this:</P> |
| |
| <BLOCKQUOTE> |
| <P>C:\myapp\<BR> |
| C:\myapp\acmeEjbs\<BR> |
| C:\myapp\acmeEjbs\META-INF\ejb-jar.xml<BR> |
| C:\myapp\acmeEjbs\org\acme\Foo.class<BR> |
| C:\myapp\acmeEjbs\org\acme\FooBean.class<BR> |
| C:\myapp\acmeEjbs\org\acme\FooHome.class<BR> |
| C:\myapp\acmeEjbs\org\acme\Bar.class<BR> |
| C:\myapp\acmeEjbs\org\acme\BarBean.class<BR> |
| C:\myapp\acmeEjbs\org\acme\BarHome.class</P></BLOCKQUOTE> |
| |
| <P>Then you would delcare a 'Deployments' element with the 'dir' attribute set to 'C:\myapp\acmeEjbs' as shown below.</P> |
| |
| <DIV class="code"><DIV class="codeHeader"><B>openejb.conf</B></DIV><DIV class="codeContent"> |
| <PRE class="code-xml"><SPAN class="code-tag"><openejb></SPAN> |
| ... |
| |
| <SPAN class="code-tag"><Deployments dir=<SPAN class="code-quote">"c:\myapp\acmeEjbs"</SPAN> /></SPAN> |
| <SPAN class="code-tag"></openejb></SPAN></PRE> |
| </DIV></DIV> |
| |
| <P>Note that this syntax is the same as the directory syntax above. If OpenEJB finds a META-INF directory with an 'ejb-jar.xml' fine inside, then OpenEJB will treat the directory as an unpacked ejb jar. Otherwise OpenEJB will look for ejb jar files to load as detailed in the above section.</P> |
| |
| <H1><A name="ManualdelUsario-Logfile"></A>Log file </H1> |
| |
| <P>When trying to figure out if your ejbs were loaded, the openejb.log file is an incredible asset.</P> |
| |
| <P>If your ejbs were loaded successfully you should see entries like the following (1.x and higher only):</P> |
| |
| <DIV class="panel"><DIV class="panelHeader"><B>openejb.log</B></DIV><DIV class="panelContent"> |
| <P>INFO : Loaded EJBs from /usr/local/openejb-1.0-beta1/beans/openejb-itests-beans.jar<BR> |
| INFO : Loaded EJBs from /usr/local/openejb-1.0-beta1/beans/openejb-webadmin-clienttools.jar</P> |
| </DIV></DIV> |
| |
| <P>If your ejbs failed to load, you will see an entry similar to the following.</P> |
| |
| <DIV class="panel"><DIV class="panelHeader"><B>openejb.log</B></DIV><DIV class="panelContent"> |
| <P>WARN : Jar not loaded. /usr/local/openejb-1.0-beta1/beans/helloworld.jar. Jar failed validation. Use the validation tool for more details</P> |
| </DIV></DIV> |
| |
| <P>Additionally, all the successfully loaded ejbs are individually listed in the log file at startup. The Deployment ID listed is the JNDI name used to lookup the ejb from a client of the Local or Remote Servers. The beans listed below are from our test suite.</P> |

| <H2><A name="ManualdelUsario-ConfiguringyourContainer"></A>Configuring your Container</H2> |
| |
| <P>Of course, if you did have a configuration like the one above, it would be a bit pointless as all three of your CMP containers would be using the default CMP container configuration. To acually configure a container differently, you simply need to specifiy new values for the properties that the container has. These will override the defaults for that particular container declaration. So it's possible to declare multiple containers of the same type, but configure each one differently. Let's use our CMP_ENTITY containers above as an example.</P> |

| <P>The format of the configuration parameters is actually just regular old java.util.Properties file format. It keeps things simple and doesn't require you to type endless amounts of tags that are just name/value pairs anyway. The java.util.Properties file format allows for spaces, tabs, colons, or equals signs to separate the name value pairs, so this would also be acceptable..</P> |
