I am using spring and hibernate. I have mapping locations specified as:
My folder structure is as follows:
src/main/resources
.
...hibernate
.
.....hibernate2
<property name="mappingLocations" value="classpath:hibernate/*.hbm.xml" />
above property is looking into only hibernate folder and is not looking into subfoders. how can i force to find hbm files in sub folders as well?
Insert a wildcard * as below
<property name="mappingLocations" value="classpath*:hibernate/**/*.hbm.xml" />

In my application, I have specified the below configuration for automatically picking up all the HBM files under a specific folder in the classpath.
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="mappingLocations">
<list>
<value>classpath:hbms/**/*.hbm.xml</value>
</list>
</property>
</bean>
Now, for a new requirement, there is a need to create multiple HBM files with named queries specific to database. The HBM file names will be of the pattern test.DB.hbm.xml. For example, test.oracle.hbm.xml and test.db2.hbm.xml. In addition to these, there are the old regular HBM files (for mapping to tables) with name format as table1.hbm.xml, table2.hbm.xml, etc. also present in the same folder.
Using the above pattern, hibernate loading of the files fails, due to duplicate named queries in the new hbm files (since the name would be same in all such files).
The requirement is now to load the regular HBM files and also the DB specific HBM files. Is it possible to achieve this by using a regular expression as below?
classpath:hbms/**/*.(.${dbType}).hbm.xml
In the above example, dbType is available as a Spring environment property. My attempt with these changes resulted in none of the HBM files being loaded (including the old ones).
Am I doing something wrong with the regular expression or is it not possible to do this via XML configuration?
Thank you.
You have two options:
You can have each database specific config files be stored in a separate folder and then your config looks like this:
classpath:hbms/**/${dbType}/*.hbm.xml
You can have them follow he pattern you provided, but change the configuration to
classpath:hbms/**/*${dbType}.hbm.xml
To load common files, you need to rename them to include something you can match, like:
one.hbm.xml
becoming:
common-one.hbm.xml
Then the configuration might look like this:
classpath:hbms/**/common-*.hbm.xml
classpath:hbms/**/*${dbType}.hbm.xml
I want to read an external properties file when launching Jboss 4.2 . I want to add it to the classpath to read it from a WAR file . I have seen different solutions with Jboss 6 using modules, but I haven't seen anything related to JBoss 4.2.
I have included inside 'jboss-service.xml' the following code :
<!-- Bean for reading properties -->
<mbean code="org.jboss.varia.property.SystemPropertiesService"
name="jboss.util:type=Service,name=SystemProperties">
<!-- Load properties from each of the given comma separated URLs -->
<attribute name="URLList">
./conf/path.tmview.properties
</attribute>
</mbean>
In this file I have defined the property :
property-placeholder filepath=/var/tmview_props/tmview/tmview.properties
This property is used in the following bean definition
<bean id="tmviewConfigurerLocation" class="org.springframework.core.io.FileSystemResource">
<constructor-arg value="${property-placeholder-filepath}" />
</bean>
inside an applicationContext.xml . When I launch jboss, the file of properties is read
15:45:29,939 INFO [SystemPropertiesService] Loaded system properties
from: file:/D:/devel/projects/tmview/deployment/jboss-
...ver/tmview/conf/path.tmview.properties
So, the property is read, but I kept obtaining the following exception
2015-03-24 15:45:39,219 ERROR
[org.springframework.web.context.ContextLoader] Context
initialization failed
org.springframework.beans.factory.BeanInitializationException: Could
not load properties; nested exception is
java.io.FileNotFoundException: ${property-placeholder-filepath} (The
system cannot find the file specified)
at
org.springframework.beans.factory.config.PropertyResourceConfigurer.
postProcessBeanFactory(PropertyResourceConfigurer.java:78)
Is there any special way to read the property inside the spring bean ?
In jboss 4 you was able to drop property files in the <jboss_home>/server/<instance>/conf directory and they would be available from the classpath.
Another possibility is add your custom directory to the classpath, to do this see Adding second conf folder to JBoss 5.1.0
Ok . At the end , I solved the problem . It seems the problem was located in reading from application-context.xml .
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location">
<value>file:${tmview.conf.variables}</value>
</property>
</bean>
I had to add a property placeholder reader . Regarding to jboss, you can read the parameter file either from conf/jboss-service.xml or deploy/properties-receive.xml, but it seems more appropiate to do the reading from the second one .
I want to export my jpa/swing project to a runnable jar. But I want the persistence.xml to be outside the jar not packaged inside, so I can change it without the need to export the jar again after each config.
According to JPA specifications, persistence.xml file cannot be detected outside the JAR file where the persistence unit is defined. By convention, it should be placed inside META-INF directory.
Read JSR-317, paragraph 8.2.1 for more details (http://download.oracle.com/otndocs/jcp/persistence-2.0-fr-eval-oth-JSpec/).
Nevertheless, you can try the hint proposed by this guy here and deploy your archives in exploded form.
I had the same problem, but I only needed to change Server, database, user and password. So this did it for me:
In JBoss AS, you can even have the property value as a placeholder, for example:
<property name="javax.persistence.jdbc.url" value="jdbc:sqlserver://${DbServer}:1234;databaseName=${DbName}" />
<property name="javax.persistence.jdbc.user" value="${DbUser}" />
<property name="javax.persistence.jdbc.password" value="${DbPassword}" />
and then pass the "DbServer", "DbName", "DbUser" and "DbPassword" value as a Java system property:
-DDbServer=sql99 -DDbName=db_Name -DDbUser=USER -DDbPassword=pw
In Eclipse:
I am trying to use Hibernate 3.2.5 with Play framework 1.2.5
In Hibernate I am having two files:
1) cfg.xml file (containing the db config details along with some additional properties
2) hbm.xml file (containing the mapping between the java bean and the db table
For getting connected to the oracle 10g db, I am providing the db details in the application.config files like this and the connection is successful also when I start the server:
db.url=jdbc:oracle:thin:#localhost:1521/orcl
db.driver=oracle.jdbc.OracleDriver
db.user=system
db.pass=tiger
I want to know Where will I place the hbm.xml file (for mapping details) and the cfg.xml file for the remaining properties other than db connecion details?
Please let me know about this.
Regards,
Starting from the root directory of your application:
the hibernate.cfg.xml must be placed inside the app directory
the mapping files (the hbm files) where your models classes are defined, usually inside the app/models/ directory
Inside your hibernate.cfg.xml the mapping attributes should be something like:
<mapping class="models.yourHmbFile1"/>
<mapping class="models.yourHmbFile2"/>
Btw, I find easy to use the hibernate annotations instead of the hbm - xml mapping. Easier to write and to mantain.
If you prefer to annotate your model classes, you can delete the hbm files and directly map your annotated classes in your hibernate.cfg.xml.
In the application.conf you've to specify the data you have already added:
db.url=jdbc:oracle:thin:#localhost:1521/orcl
db.driver=oracle.jdbc.OracleDriver
db.user=system
db.pass=tiger
Also in the hibernate.cfg.xml you need to specify the connection data:
<property name="hibernate.dialect">...</property>
<property name="hibernate.connection.driver_class">...</property>
<property name="hibernate.connection.url">...</property>
<property name="hibernate.connection.username">...</property>
<property name="hibernate.connection.password">...</property>
I have one instance of SOLR with three different cores.
I created a solr.xml config file which specifies the schema file for each core, but, it is not recognized. The system still tries to load the default schema.xml (I removed it, so it fails).
For debugging purposes I left only one code in the solr.xml, here are the entries I have:
<solr persistent="false">
<cores adminPath="/admin/cores" defaultCoreName="content" shareSchema="false">
<core name="content" instanceDir=".">
<property name="schema" value="conf/contentSchema.xml" />
</core>
</cores>
</solr>
The file `contentSchema.xml exists under [SOLR_HOME]/conf. Itried both just the file name and conf/filename
Don't even reach that phase, the error is:
SEVERE: java.lang.RuntimeException: Can't find resource 'schema.xml' in classpath or
/usr/local/solr/./conf/', cwd=/usr/local/solr
If you have source downloaded , check the multicore folder which demos the multicore configuration which you can refer and test.
or refer # http://svn.apache.org/repos/asf/lucene/dev/trunk/solr/example/multicore/
More # http://wiki.apache.org/solr/CoreAdmin#Configuration - would be a good starting point.
The multicore need not be under the solr home folder and can be specified with
-Dsolr.solr.home=multicore
The solr.xml is in the same folder as the core folders.
The instance directory points to the core folders
schemaName -- The name of the core's schema file (schema.xml by default)
e.g.
<core name="content" instanceDir="content">
<property name="schemaName" value="contentSchema.xml" />
</core>
Read the document carefully, 'schema' is an ATTRIBUTE of core element, not a PROPERTY. so suppose you put 'myschema.xml' under core's conf folder:
<core ....>
<property name="schema" value="myschema.xml" />
</core>
will cause can't find schema.xml in classpath or ...../conf error
Whereas,
<core .... schema='myschema.xml' />
will succeed.
Note: Lucid Imagination's doc may be out-of-date or maybe it's talking about a feature of a future version of Solr, I guess.
This is what I finaly used and is working
<cores adminPath="/admin/cores" defaultCoreName="content">
<core name="content" instanceDir="./content" />
<core name="users" instanceDir="./users" />
<core name="users_organizations" instanceDir="./users_organizations" />
</cores>
Under each of those directories I have a conf directory with it's own conf files, which they in turn also point to the right data folder (in the solrconfig.xml file)
