[EJB/JBoss] - jboss throws an exception when casting a proxy class
by jborra
Hi all,
A casting exception is thrown when my servlet tries to bind to an EJB. I am running jboss-4.2.2.GA. Java version 1.6.0_05.
I have a servlet that tries to get a reference to a session ejb as in the following code:
1. InitialContext initialContext = new InitialContext();
2. j2eetest.ejb.ConfigurationRemoteHome configurationRemoteHome = (j2eetest.ejb.ConfigurationRemoteHome) initialContext.lookup("ConfigurationBean");
3. ConfigurationRemote configurationRemote = configurationRemoteHome.create();
When line '2.' is executed I get the following exception:
20:42:13,140 ERROR [[/J2EETest-war]] StandardWrapper.Throwable

When inspecting JNDIView in jboss' JMX Console I see the following entry under the Global JNDI Namespace
...
+- ConfigurationBean (proxy: $Proxy71 implements interface j2eetest.ejb.ConfigurationRemoteHome,interface javax.ejb.Handle)
...
which makes me believe that, as $Proxy71 implements the ConfigurationRemoteHome interface, there shouldn't be any problem when casting the reference returned by InitialContext.lookup(...) into the indicated type.
What could be the root of the problem I experience?
Thank you for your help,
Jesus Borra

[Tomcat, HTTPD, Servlets & JSP] - Unable to pre-compile JSP using ANT task with JBoss 4.2.2
by depryf
Hi,
We recently switched from JBoss 4.0.4 to JBoss 4.2.2 (I know, this is a big jump). We used to have an ant task that pre-compiled all our JSP.
That stopped working under 4.2.2 with the following message:
| jspc:
| [echo] Compiling JSPs...
|
| BUILD FAILED
| C:\projects\seerdms\build.xml:649: org.apache.jasper.JasperException: Unable to initialize TldLocationsCache: XML parsing error on file /WEB-INF/tld/struts-html.tld
|
Here is the ant task we are using:
| <target name="jspc">
| <echo message="Compiling JSPs..." />
|
| <taskdef classname="org.apache.jasper.JspC" name="jasper2">
| <classpath>
| <pathelement location="${java.home}/../lib/tools.jar" />
| <pathelement location="${deploy.dir}/jboss-web.deployer/jbossweb.jar" />
| <pathelement location="${deploy.dir}/../../../lib/jboss-common.jar" />
| <pathelement location="${lib.dir}/eclipse/javaee.jar" />
|
| <path refid="cp.jasper2" />
| </classpath>
| </taskdef>
|
| <jasper2 compile="false" validateXml="false" uriroot="${build.war.files.dir}" webXmlFragment="${registry.build.dir}/generated_web.xml" package="${package.web}" outputDir="${registry.build.dir}/jsp-src" />
|
| <javac srcdir="${registry.build.dir}/jsp-src" destdir="${registry.build.dir}/classes" listfiles="${compile.listfiles}" failonerror="${compile.failonerror}" debug="${compile.debug}" debuglevel="${compile.debuglevel}" optimize="${compile.optimize}" deprecation="${compile.deprecation}">
| <classpath>
| <fileset refid="fileset.jasper2" />
| <path refid="cp.lib" />
| </classpath>
| </javac>
|
| </target>
|
I am not totally familiar with the TLD files, but here are the beginning of the struts-html.tld file that is not successfully parsed:
| <?xml version="1.0" encoding="UTF-8"?>
|
| <!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN" "http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd">
| <taglib>
| <tlibversion>1.0</tlibversion>
| <jspversion>1.1</jspversion>
| <shortname>html</shortname>
| <uri>http://jakarta.apache.org/struts/tags-html</uri>
| <tag>
| <name>base</name>
| ...
|
Thank you!
