There is no XSLT 2.0 support in the JDK as of 7.0. According to Stackoverflow , there are three Java packages that support XSLT 2.0: Saxon IBM WebSphere XML Feature Pack Oracle XDK There are no known support for XSLT in browsers. According to Wikipedia : XSLT is developed by the World Wide Web Consortium (W3C). The most recent version is XSLT 2.0, which reached W3C recommendation status on 23 January 2007. As of 2010, however, XSLT 1.0 is still widely used, as there are no products that support XSLT 2.0 running in the browser, nor on some important server environments such as LAMP. Expressions like this: format-date(xs:date('1999-12-31'), '[D01] [MNn] ... where format-date is a XSLT 2.0 function and date is a XPath 2.0 constructor...

Step 1: Repackage a web app as EAR A Java EE application is a multimodule Maven project. At the very least you'll need to package a WAR and an EAR. To get started, I'll simply re-package the simple webapp as an EAR. Create a directory named javaee-app Copy the webapp from here to javaee-app . Rename struts1app to webapp . Create pom.xml under javaee-app : <project> <modelVersion>4.0.0</modelVersion>... Create a directory named ear under javaee-app . Create pom.xml under ear : <project> <modelVersion>4.0.0</modelVersion>... Modify pom.xml in the webapp directory so that it looks like this: <project> <modelVersion>4.0.0</modelVersion> ... Build with " mvn package " in the javaee-app directory. You can see that ear-1.0.ear is successfully generated in javaee-app/ear/target . Maven successfully resolves dependencies between the sub-projects....

I get this error using PL/SQL to enqueue a JMS message in Oracle XE: Oracle: PLS-00302: component 'CONSTRUCT' must be declared . Following an advice I found on the web , I ran the script "$ORACLE_HOME/rdbms/admin/prvtaqal.plb" as SYS in sqlplus. That worked even though I got a bunch of errors running the script: Warning: Package created with compilation errors. ...

This is the stack trace from a SOAP stub generated by Oracle OC4J 10.1.3: C:\tmp>java -Xmx128M TestWs Exception in thread... Turned out that this was a server side error (out of memory on server, as can be guessed from the exception), which in my case was running Oracle OC4J. Restarting the server with switch -Xmx128M fixed the problem. The weird thing was that it was running fine when requesting the same web service from Firefox or IE (instead of the standalone Java client).

This procedure works for Oracle application server 10.1.3.1, SOA suite. But should be applicable for standalone OC4J or JDeveloper installations with minor modifications. $ORACLE_HOME is the home directory for Oracle app server. $JDEV_HOME is the home directory for JDeveloper. 1. Change directory to $ORACLE_HOME/j2ee , mkdir lib 2. Copy xmlparserv2.jar from $JDEV_HOME to $ORACLE_HOME/j2ee/lib . 3. Copy ocj.jar and jdev_remote.jar from $JDEV_HOME/jdev/lib to $ORACLE_HOME/j2ee/home/lib . 4. Edit global-web-application.xml under your OC4J instance's config directory. Change the development attribute to true . <orion-web-app xmlns:xsi="http://www.w3.org/... 5. Add the following to the servlet section of global-web-application.xml : <servlet> <servlet-name>jsp</servlet-na... 6.

When I ran the genInterface task, I got a weird message saying that it "Failed to find wsa.jar", although the interfaces were correctly generated. <target name="gen-interface" depends="init" de... After some digging, I found that setting the environment variable ORACLE_HOME to where JDeveloper is installed makes it disappear. On Windows XP, I have to set ORACLE_HOME in all caps, set oracle_home doesn't work, even though Windows is case insensitive.

I had this problem when deploying a J2EE application into Oracle app server. It worked fine with an OC4J container configured in the default group. But it failed to start with an OC4J container I created. Here's a sample stack trace of the initialization exception: 07/08/14 13:32:46.34 10.1.3.3.0 Started 07/08/1... The problem was, the struts ActionServlet loads commons logging LogFactory, the log factory somehow knows that it needs log4j, but it can't load log4j since it's loaded by a different class loader. The solution for Oracle is to omit commons logging from the list of inherited libraries. Add this to META-INF/orion-application.xml solves the problem: <imported-shared-libraries> <remove-inhe... Actually, this is a quite common problem with commons-logging. If you search the web, you'll find that people have...

If you use quartz or the plain old java.util.Timer class to schedule jobs in an OC4J container, you need to enable the -userThreads switch with the OC4J container. This is the relevant section in $ORACLE_HOME/opmn/conf/opmn.xml : <process-type id="INST1" module-id="OC4J" status="... Or, you can add it through the Oracle em console. Go to the OC4J container, click "Administration" tab, then "Server Properties". Add "-userThreads" to "Start-parameters: OC4J Options". Debu Panda has written a good article on using quartz in the Oracle environment: Using Quartz Enterprise Scheduler in J2EE
