If you access an HTTP service, you have to use http. If you are counting on retrieving schemas or DTDs over the internet, you're building a slow, chatty, fragile application. What happens when that remote server hosting the file takes planned or unplanned downtime? Your app breaks. Is that OK? URL's for schemas and the like are best thought of as unique identifiers.
Not as requests to actually access that file remotely. Do some google searching on "XML catalog". An XML catalog allows you to host such resources locally, resolving the slowness, chattiness and fragility.
It's basically a permanently cached copy of the remote content. And that's OK, since the remote content will never change. If there's ever an update, it'd be at a different URL. Making the actual retrieval of the resource over the internet especially silly. This is a minor update, but since Java 7, proxy connections can now be created programmatically rather than through system properties. This may be useful if:. Recently I've discovered the way to allow JVM to use browser proxy settings.
The only problem with this approach is that you need to start JVM with deploy. If somebody knows how to overcome this limitation, let me know. As is pointed out in other answers, if you need to use Authenticated proxies, there's no reliable way to do this purely using command-line variables - which is annoying if you're using someone else's application and don't want to mess with the source code. For example with Proxifier you can set it up to only intercept java commands to be managed and redirected through its authenticated proxy.
You're going to want to set the proxyHost and proxyPort values to blank in this case though, e. You can utilize the http. Additionally, for WebSphere and WebLogic you will likely break your application server in little ways by overriding the startup scripts particularly the server's interop processes as you might be telling them to use your proxy as well Many programs including Windows Updates are having problems behind proxy.

Thanks — Joeblackdev. Sometimes this may be due to some nasty classpath issue, but most often this is due to missing JAR in the classpath. Solution: If it's a case of a missing JAR file then issues will be solved as soon as you deploy the commons-logging You need to first find those JAR files on the internet and then hope that there is no version mismatch error e.
That's why it's best to use Maven to download and manage dependency JAR files. Maven will not only automatically download the JAR file for you but also it will ensure that the correct versions of transitive dependent JARs are downloaded. In order to add commons-logging JAR using Maven, you can add the following dependency in your pom.
How to fix java. ClassNotFoundException: com. Driver in Java? Let's have a look at the pages. Seam drastically reduces the amount of xml coding that needs to be done. One file that is of interest is the pages. The pages. Among other things it can be used in a Seam application to define exception handlers and redirections.
In the case of our sample application we are using it to define a Seam page parameter. This defines a parameter named tid for the edit. When the edit. This completes our walkthrough of the sample Seam application. For further, detailed information on developing applications using the Seam framework, please refer to the The Seam Reference Guide.
This datasource is configured to use the embedded Hypersonic database instance shipped by default with the distribution. Having a database included with JBossAS is very convenient for running the server and examples out-of-the-box. However, this database is not a production quality database and as such should not be used with enterprise-class deployments. As a consequence of this JBoss Support does not provide any official support for Hypersonic. In this chapter we will explain in details how to configure and deploy a datasource to connect JBossAS to the most popular database servers available on the market today.
Datasource configuration file names end with the suffix -ds. Local transaction datasources are configured using the local-tx-datasource element and XA-compliant ones using xa-tx-datasource. The example file generic-ds. If you look at the example files firebird-ds. The syntax is not specific to datasource configuration and is used, for example, in the jms-ds.
This database server is used in millions of installations ranging from large corporations to specialized embedded applications across every continent of the world. In this section, we'll be using the community version of their database server GA 5.
Then create a text file in the deploy directory called mysql-ds. The datasource is pointing at the database called test provided by default with MySQL 5. Using the test client described in Section Oracle is one of the main players in the commercial database field and most readers will probably have come across it at some point. Then create a text file in the deploy directory called oracle-ds.
Before you can verify the datasource configuration, Oracle XE should be reconfigured to avoid port conflict with JBossAS as by default they both start a web server on port The web server started by Oracle XE to provide http-based administration tools is now running on port Start the JBossAS server instance as you would normally do.
You are now ready to use the test client described in Chapter 6. Then create a text file in the deploy directory called mssql-ds.
The persistence manager of JBoss Messaging uses the default datasource to create tables to store messages, transaction data and other indexes. Configuration of "persistence" is grouped in xxx-persistence-service. JBoss Application Server ships with a default hsqldb-persistence-service. You can view the hsqldb-persistence-service. Please note that the Hypersonic database is not recommended for production environments due to its limited support for transaction isolation and its low reliability under high load.
First of all, you should create an exploded WAR archive under the deploy directory which is simply a folder named " jdbcclient. In this folder, create a text document named client. A list of users and password should show up as a result of the jdbc query:. O'Reilly, Norman Richards, Sam Griffith. Manning, Christian Bauer, Gavin King. Prentice Hall, Michael Yuan, Thomas Heute.

This defines the core services that are fixed for the lifetime of the server. It holds persistent data for services intended to survive a server restart. Serveral JBoss services, such as the embedded Hypersonic database instance, store data here. It also contains applications for the current server configuration. The directory is constantly scanned for updates, and any modified components will be re-deployed automatically.
You can add required library files here for JDBC drivers etc. All JARs in this directory are loaded into the shared classpath at startup. JBoss uses the Jakarta log4j package for logging and you can also use it directly in your own applications from within the server. The deployer, for example, expands application archives in this directory. The "default" Server Configuration File Set. Contents of "conf" directory. File Description jboss-minimal.
This is the jboss-service. Contents of "deploy" directory. File Description bsh-deployer. It is disabled by default. It sets up the embedded database and related connection factories. It provides the connection management facilities for integrating resource adaptors into the JBoss server. This is similar to the legacy jmx-rmi-adaptor. The "all" Server Configuration File Set.
