[JBoss AOP] - Re: NullPointerException at advised._getInstanceAdvisor();
by robotics80
I rewrite the jboss-aop.xml file because I failed to insert its code:
<!-- Declaring pointcuts -->
| <pointcut name="allPublicMethod"
| expr="execution(public * it.pitagora.sqtp.server.aicagw.fastdeferred.FileFinder->*(..))"/>
| <pointcut name="mainMethod"
| expr="execution(void it.pitagora.sqtp.server.aicagw.fastdeferred.FileFinder->main(..))"/>
| <pointcut name="constructorPointcut"
| expr="execution(it.pitagora.sqtp.server.aicagw.fastdeferred.FileFinder->new(..))"/>
| <pointcut name="logObject" expr="set(it.pitagora.util.log.Log it.pitagora.sqtp.server.aicagw.fastdeferred.FileFinder->*)"/>
|
|
| <!-- Declaring Aspects -->
| <aspect name="logAspect" class="aop.batch.interceptor.LogAspect" scope="PER_INSTANCE">
| <attribute name="PropertyFile">aicagw.properties</attribute>
| </aspect>
|
|
| <!-- Binding pointcuts to Interceptors
| <bind pointcut="(allPublicMethod OR constructorPointcut) AND !mainMethod">
| <interceptor-ref name="logInterceptor"/>
| </bind>
| -->
|
| <!-- Binding pointcuts to Aspects -->
| <bind pointcut="logObject">
| <advice name="getLogger" aspect="logAspect"/>
| </bind>
|
| <bind pointcut="(allPublicMethod OR constructorPointcut) AND !mainMethod">
| <advice name="trace" aspect="logAspect"/>
| </bind>
The error happens when I declare a pointcut expression like this:
| <pointcut name="prova" expr="call(public it.pitagora.util.log.Log->new(..)) AND within(it.pitagora.sqtp.server.aicagw.fastdeferred.FileFinder)"/>

[JBoss Seam] - Facelets error
by thejavafreak
I get this error when Initializing a seam-gen generated application. I deployed the application on JBoss AS 5.0.0Beta1. Are there any workaround for this? It seems the error is harmful.

[JBoss AOP] - Re: NullPointerException at advised._getInstanceAdvisor();
by robotics80
I have the main application in a file FileFinder.java that use a logger object to log its operations into a file. The FileFinder build this log object in a method init() and I want to create an aspect for logging interception that is able to intercept the log object build in method init() of FileFinder class and use this object to log operations.
A part of FileFinder.java code is:
public class FileFinder {
private SqlMapClient sqlMapClient;
private Log log;
private IniReader ini;
private InstanceManager instanceManager;
private SessionTask sessionTask;
private int errorReq = 0;
private int discardedReq = 0;
private static final String className = "FileFinder";
/**
* @throws DeferredException
*
*/
public FileFinder() throws DeferredException {
init();
}
/**
* @throws DeferredException
*
*/
private void init() throws DeferredException {
String proc = className + ".init()";
try {
ini = new IniReader(Env.getSqtpHome() + "etc/aicagw.properties");
log = new Log(ini);
log.logInit("AICAGW.FILEFINDER","BATCH");
log.setPid();
logInfo(proc,"START");
long startTime = System.currentTimeMillis();
//creazione file gestione esecuzione singola istanza del batch
String workingFolder = ini.getPrivateProfileString("AICAGW.COMMON","WORKINGFOLDER","/");
String instancefileName = "fileFinder";
logInfo(proc,"file per gestione esecuzione singola istanza del batch: " + workingFolder + "/" + instancefileName);
instanceManager = new InstanceManager(workingFolder,instancefileName);
//creazione sessione
sessionTask = new SessionTask(log);
sessionTask.setSessionName(""+startTime);
//accesso a db tramite iBatis
sqlMapClient = SqlMapClientConfig.getClient("AICAGW", "BATCH");
logInfo(proc,"END");
} catch (Exception e) {
DeferredException de = CommonDeferred.wrapException(e);
logErr(proc, de.toString());
throw de;
}
}
//... and some other methods
}
A part of LogAspect.java code is:
public class LogAspect {
private static final String className = "LogAspect";
private static final String DBG_ERROR = "ERROR";
private static final String DBG_WARNING = "WARNING";
private static final String DBG_INFO = "INFO";
private static final String DBG_TRACE = "TRACE";
private String propertyFile;
private Log log;
private IniReader ini;
/*
private void init() throws Exception {
String proc = className + ".init()";
try {
ini = new IniReader(Env.getSqtpHome() + "etc/" + propertyFile);
log = new Log(ini);
log.logInit("AICAGW.FILEFINDER","BATCH");
log.setPid();
} catch (IOException e) {
logErr(proc, e.getMessage());
throw e;
}
}
*/
public void setPropertyFile(String propertyFile) {
this.propertyFile = propertyFile;
}
public void setLog(Log log) {
this.log = log;
}
public String getName() {
return "LogAspect";
}
public Object getLogger(Invocation invocation) throws Throwable{
try{
System.out.println("INGRESSO nel getLogger()");
if (invocation instanceof FieldWriteInvocation) {
FieldWriteInvocation fieldInvocation = (FieldWriteInvocation)invocation;
setLog((Log)fieldInvocation.getValue());
} else
System.out.println("Unknown Invocation!!");
return invocation.invokeNext();
} finally {
System.out.println("USCITA dal getLogger()");
}
}
public Object trace(Invocation invocation) throws Throwable{
String proc = className + ".trace()";
long startTime = System.currentTimeMillis();
logInfo(proc, "START");
logTrace(proc, invocationTypeValue(invocation));
Object response = null;
try {
response = invocation.invokeNext();
return response;
}catch(Throwable t) {
long endTime = System.currentTimeMillis();
long elapsedTime = endTime - startTime;
logErr(proc, t.getMessage() + " - Tempo di esecuzione (ms): " + elapsedTime);
throw t;
}
finally {
long endTime = System.currentTimeMillis();
long elapsedTime = endTime - startTime;
logTrace(proc,dumpInvocationResponse(invocation, response) + " - Tempo di esecuzione (ms): " + elapsedTime);
logInfo(proc, "END");
}
}
public String dumpInvocationResponse(Invocation invocation, Object response) {
// some code
}
private String invocationTypeValue (Invocation invocation) {
// some code
}
private void logErr(String proc, String message) {
System.out.println(DBG_ERROR + ": " + message);
if (log != null) {
log.logWrite(log.DBG_ERROR, proc, message);
}
}
private void logWarning(String proc, String message) {
System.out.println(DBG_WARNING + ": " + message);
if (log != null) {
log.logWrite(log.DBG_WARNING, proc, message);
}
}
private void logInfo(String proc, String message) {
System.out.println(DBG_INFO + ": " + message);
if (log != null) {
log.logWrite(log.DBG_INFO, proc, message);
}
}
private void logTrace(String proc, String message) {
System.out.println(DBG_TRACE + ": " + message);
if (log != null) {
log.logWrite(log.DBG_TRACE, proc, message);
}
}
}
The jboss-aop.xml file is:
<!-- Declaring pointcuts -->
<!-- Declaring Aspects -->
<!-- Binding pointcuts to Aspects -->
In this way It works fine because I use the pointcut expression set(..) and a FieldWriteInvocation to intercept the log object when it is assigned in a log variable into FileFinder class.
But if I use the pointcut expression call(..) to intercept the construction of the Log object in the FileFinder.init() method, I got the NullPointerException like this:
N.B. Remember tha I run this file with load time weaving activated with option -javagent:..... JDK 1.5 and the latest version JBoss AOP 1.5.2.GA
Is there anyone that is able to solve this problem?

Sure, ofcourse!

Right, its just a WAR.

You can't use EJB3.
Have you looked at the examples yet? the "jpa" and "hibernate2" examples both deploy on WL.

It was working fine just before, so it's probably something small.

[JBoss jBPM] - Jbpm on Tomcat 5.5
by srsuarez
I am trying to run Jbpm on Tomcat 5.5. I have done these steps, but I have some questions:
Steps
(1) Download jbpm-starters-kit-3.1.1 from Jboss site
(2) Deploy jbpm-starters-kit-3.1.1\jbpm-server\server\jbpm\deploy\jbpm.war into tomcat webapps.
(3) Copy hibernate.cfg.xml from jbpm-starters-kit-3.1.1\jbpm\src\config.files to ur <jbpm-home>/WEB-INF/classes/
(4) Run ant task for creating database tables and data from jbpm-starters-kit-3.1.1\jbpm\build.deploy.xml
( ant create.db ?buildfile build.deploy.xml)
(5) Add few jars to lib folder of your application.
(6) Start tomcat.
(7) Start jbpm application.
Questions
* On the step (2), I have copied the "jbpm-starters-kit-3.1.1\jbpm-server\server\jbpm\deploy\jbpm.war" on tomcat webapps. Is it correct?
* When I run the jbpm application I obtain this error on the tomcat logs. I don't know why success...:

[JBoss Seam] - Seam 1.1 on WebLogic 9
by schneider_id
Hello Seam/JBoss-Team,
I'm interested in the deployment and integration details of running Seam applications within WebLogic 9.
How far is the integration between the application's Seam runtime and the WebLogic server?
Can a WL-deployed Seam application use any WL-Resources such as DataSource/ConnectionPool/JNDI/JMS-Queue/etc. from the WL server? Or (for example) do I have to configure the DB connection settings within the application's Seam configuration, separate from the WL configuration?
I assume that I don't have to change/adjust any (global) configuration of the WL server when deploying a Seam-based application (aside from the regular application deployment process), since it is just a "plain-vanilla" J2EE app from the deployment point of view. Is that correct?
Also are there any points where the application development with Seam is constrained when targeting the WL 9 platform for a deployment?
Best Regards,
Christian
