Any way is fine - console, web interface, programmatically...
I was unable to find the DB version in the web interface yet and even the jars in the {$JBOSS_HOME}/common/lib don't have the version in the filename.
The JBoss version is 5.1 EAP
Thank you
If you go to where the HSQLDB database is stored:
{$JBOSS_HOME}/Server/XXX/data/hypersonic
and open the localDB.properties file, at the top it will have the version, like this:
#HSQL Database Engine 1.8.0.8
If there is no database properties file handy, try unzipping hsqldb.jar, and looking in the META-INF/MANIFEST.MF file for something like this:
Specification-Version: 1.8.0.10
You can also detect the HSQLDB version using SQL
select character_value
from information_schema.sql_implementation_info
where implementation_info_name = 'DBMS VERSION'

I am pretty new to java DB and I'm trying to set up Java DB in NetBeans IDE using this tutorial: https://netbeans.org/kb/docs/ide/java-db.html
During the step, where it tells to create database, I get such an error:
An error occurred while creating the database: java.lang.ClassNotFoundException: org.apache.derby.jdbc.Clientdriver
How do I fix this issue?
Which version of Derby / JavaDB are you using?
If it is 10.15.1.3, see this response: Where is org.apache.derby.jdbc.ClientDriver for version 10.15.1.3?
Within Netbeans there seems to be the same issue with ClientDriver. As a workaround, download and use Derby 10.14.2.0 instead. A Netbeans bug report Apache JIRA Netbeans-3424 (https://issues.apache.org/jira/browse/NETBEANS-3424) has been submitted.
I found it in lib\derbytools.jar\org\apache\derby\jdbc
copied the entire jdbc folder and pasted in lib\derbyclient.jar\org\apache\derby
then it works.
Goodbye.
I've installed Talend ESB 6.5.1 and am trying to connect to a SQL Server database.
I tried using the JTDS driver, but that didn't work, and it appeared that I needed a DLL that wasn't included in the , and do I installed the pure java MS driver instead.
Talend has put the MS driver into Studio\workspace\xxx\temp\dbWizard having renamed it, but when I try to use it I get
Database connection is failed.
java.lang.RuntimeException: java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver
at org.talend.core.model.metadata.builder.database.JDBCDriverLoader.getConnection(JDBCDriverLoader.java:195)
...
It looks like Talend has put the jdbc driver somewhere, but it not referencing it correctly.
Any ideas what I need to do to get Talend to find it? (I've looked inside the .jar file and the class is definitely there.)
(Taking the generated JDBC URL and using this directly in a tJDBCInput with the driver jar selected works fine... bizarre)
The location where your jar was put does not look familiar. Try deleting all the jtds jar versions in the following locations :
<Talend root folder>\configuration\.m2\repository\org\talend\libraries
<Talend root folder>\lib\java
And restart your studio. When you go back to your component, you'll see an install button. You should be able to download and install the jar.
I just upgraded AEM from version 6.2 to Version 6.3. I see a folder called archived-versions created under crx-quickstart. Is it safe to delete the contents inside that folder?
I found a reference to archived-versions in an older upgrade documentation.
Note that your existing crx-quickstart/bin/ will be archived below crx-quickstart/archived-versions/. The precise path is given in the output of the above java -jar command. If you have customized any of the scripts in this directory, you can find those changed files in the archive.
https://docs.adobe.com/content/docs/en/cq/5-6-1/deploying/upgrading.html
From what I can tell it's safe to delete unless you've made modifications to start up scripts you may wish to keep.
Maybe moving all the content to a new AEM 6.3 instance instead of upgrading it is a better solution. This is usually what Adobe does with its AMS service.
Can I make jboss load system properties from a file without writing any explicit code for it?
Yes you can.
In JbossAS versions prior to 7.x there is PropertiesService. It's dead simple to use. I am using it with JBoss 5.1.0.GA, and it works like a charm.
Unfortunatelly PropertiesService mbean is absent in JBossAS 7.x, but there are other ways as described in official admin guide.
Here is another solution. Post author claims it's possible to list your properties files in command line while starting server instance:
./standalone.sh --properties=1.properties --properties=2.properties
and their contents should be added to System Properties.
I have started with data nucleus a couple of days ago.
I have downloaded the jdo tutorial and am trying to run it.
I have collected all the jar files related to the tutorial here .
I am using ant for building. "compile" and "enhance" tasks work fine. The "createschema" task is spitting the following error out!
C:\datanucleus\datanucleus-samples-jdo-tutorial-3.0\build.xml:123:
taskdef clas
org.datanucleus.store.rdbms.SchemaToolTask
cannot be found
I have checked datanucleus-rdbms.jar for the SchemaToolTask and I didn't find that class in the jar file.
I downloaded it from here .
Why is that class not there?? Am I using the wrong jar file?
Why would you download 3.0 and use it with a tutorial for v 1.0?
In version 3.x the location of the SchemaToolTask changed from:
org.datanucleus.store.rdbms
to:
org.datanucleus.store.schema
reflecting the fact that the Schema tool is datastore agnostic.
Found that I was using source jar files instead of the binaries.
