Eclipse + Seam + TestNG Tricky

TestNG gives "Connection Refused" while running on Eclipse

While running TestNG in Eclipse there will always be 2 VMs involved: the VM of Eclipse and the VM running the tests. In order to update the plugin UI the 2 VMs are communicating over a port using a very simple string based protocol. The exception you are seeing is telling that the 2 VMs are not able to talk to each other. This is a weird exception that would translate into: there was impossible to open a communication port between the 2 VMs involved. Off hand, the cause may be: a bug in Eclipse/plugin or maybe a firewall/antivirus that blocks this.

When running test case in Eclipse, TestNG complains bad version in .class file even Java 5 is used

java.lang.UnsupportedClassVersionError: Bad version number in .class file

Make sure everything is Java 5 compliant, such as:

• Project build path
• JAVA_HOME, JRE_HOME
• Java's in PATH (check by java -version)
• The Application Server (i.e. must be JDK5 compiled JBoss AS 5)

FAQ

When running jBPM (3.2.6.SP1) within Seam (2.1.2), the process does not run in persistent state. For example: all process instances are lost after JBoss AS restarts

In jBPM side, hibernate.cfg.xml takes the main responsibility for jBPM's persistent properties. Make sure all settings are configured properly especially:

<property name="hibernate.connection.datasource">java:JbpmDS</property>

When trying jBPM's websale example, exception occurs when clicking evaluation button

Unabled to enlist resource, see the previous warnings. tx=TransactionImple < ac, BasicAction: -3f57fffd:daa:4a702b15:1fe status: ActionStatus.ABORT_ONLY >

Could not enlist in transaction on entering meta-aware object!;

Unable to persist timer

XA data sources and jBPM

When trying jBPM's websale example (jbpm-3.2.6.SP1), AFTER clicking evaluation button and complete the task successfully, manager's task with timer causes exceptions

java.lang.UnsupportedClassVersionError: Bad version number in .class file
java.lang.ClassLoader.defineClass1(Native Method)
java.lang.ClassLoader.defineClass(ClassLoader.java:620) 

jBPM distribution maybe compiled by Java 6, use JDK6 compiled JBoss AS 5 and set JAVA_HOME and JRE_HOME to JDK6.

Regarding FSB, although theoretically speaking it should be able to operate 1066 without overclocking the FSB, many times it makes it much more stable with a higher FSB speed. This is especially apparent with AMD platforms.

Windows XP Installtion Note on K10 (Domain User)

Here I just record several steps need to go through after installation is done. AMD K10 system ONLY!!

Several things have to be changed since now I am using domain account, SoftCloud Software Platform, Windows XP SP3 etc. System configuration should be done by using administrator account.

Hardware Driver Setup

• Install Windows XP SP3
• Disable System Restore
• Format D: and E: Drives (Or Document and ProgramFiles Drives)
• Set Virtual Memory in D: Drive
• Install CPU Drivers (AMD K8 Driver, XP Fix and DualCore Optimizer
• Install 790FX Chipset Driver
• Install .Net Framework package (ATI Gfx Card ONLY!)
• Install Gfx Card Driver
• Install Audio Driver
• Install LAN Driver
• Install Mouse & Keyboard Driver

Set Up User Profile

• Setup correct IP, Gateway and DNS address that points to DC
• Join to domain NERV.HQ
• Logon as domain account after system reboot so new profile is setup
• Reboot, Logon as local administrator
• Copy domain user folder from C:\Documents and Settings to D: Drive
• Open regedit -> HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList. Change ProfileImagePath to new location from above step
• Copy back up My Documents to that new location
• Add domain user into local administrator group

Partition Size List

• 10400 --> 10GB
• 5154 --> 5GB
• 41002 --> 40GB

ActiveBPEL Exceptions Tricky

Platform: ActiveBPEL 3.1 + Tomcat 5.5.27 + Java2 SDK 1.4.2_18

The message part 'response' produced the following error during validation: cvc-complex-type.2.4.a: Invalid content was found starting with element 'vehicle'. One of '{company}' is expected.) :...

This happens when the given message is different from defined message in WSDL. Note that the order of the elements is very important: it has to be the exact same order as defined in WSDL. In BPEL, the order of Copy/To decides the order of elements appear in the message. Thus make sure the copy order is exactly the same as the element order defined in WSDL.

Error executing SOAP-RPC request. Operation not found for: bookRequest

Check if the process has been triggered and become active. If not, it's possibly caused by SOAP style type mismatch. When generating the BPP file, last step is select Binding style: mostly either Document Literal or RPC Encoding. Must select the one which is the same as defined in WSDL

Reason: WSDLException (at /schema): faultCode=INVALID_WSDL: Expected element '{http://schemas.xmlsoap.org/wsdl/}definitions'.:

The incorrect referencing the location of those XSD, WSDL documents. BPP finds the documents by referring to catalog.xml which is generated when making BPR file. So MUST generate the BPR file by using Designer to ensure consistency.

org.xml.sax.SAXException: Deserializing parameter 'clientRequest': could not find deserializer for type {http://www.travelAgent.com/book/schema}requestOrderType

XML parser could not deserialize the message. It maybe caused by given message is different from what the parser expects. For example, the client may calls WS_1 by using WS_2's endpoint address. So message types mismatch and thus could not be deserialized.

Completed with fault: missingRequest (No matching receive for reply) :  [/process/flow/reply[@name='ReplyConfirmToCustomer']] [f]

Or

org.activebpel.rt.bpel.impl.AeBpelException: No matching receive for reply

In general however you can only reply to a Receive activity once and then that thread is closed so there is no longer anything to reply to. For example start the process with an onMessage and then in the onMessage container you reply to the receive. Once you have done that then all the replies in the Fault handlers become invalid.

http://localhost/active-bpel/SOAPMonitor --> not running or capturing anything!

Enabled the Soap Monitor in ActiveBPEL by editing $CATALINA_HOME/shared/classes/ae-server-config.wsdd

Oracle OraClient Network Configuration

After Oracle OraClient has been installed, network connection can be added, edited manually from Network Configuration File. This file locates in X:\oracle\product\10.2.0\client_1\network\admin\tnsnames.ora. Its syntax looks like

ServiceName =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = HostName)(PORT = HostPort))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = ServiceName)
    )
  )
  

SVN for Eclipse Installation on Ubuntu

There are two SVN alternatives for Eclipse Subversive and Subclipse. In Windows, both of them seem work out of the box. But in Ubuntu, they require lot more steps to make it works.

Subclipse

For ubuntu and all other linux OS, a library called libsvn is required to install prior installation of Subclipse:

sudo apt-get install libsvn-java

In Eclipse, using Software Updates to obtain Subclipse, make sure include JavaHL adapter and SVNKit adapter. After installation, Eclipse may says that "JavaHL (JNI) Not Available". This is caused by JVM fails to find the libsvn library location (in /usr/lib/jni) which support JavaHL interface. Now, open eclipse.ini in eclipse installation folder and add follow line just after "-vmargs"

-Djava.library.path=/usr/lib/jni

Re-open eclipse the problem should be solved!

Update 16/12/2008 - I could not find a way to save SSH password.. which mean even time accessing the repository you are asked for password.. very annoying..

Subversive

So far, I still could not make Subversive works (the JavaHL part). Subversive contains two components that are required:

• Subversive SVN Team Provider Plugin (Incubation)
• Subversive SVN Connectors JavaHL and/or SVNKit

They can be grabbed from two different update URL check here. For some reasons, it may need to select/enable the correct update URL in Software Updates -> Manage Sites. Fail to do so may results to have old version of SVN Team Provider Plugin installed.

It seems that Subversive requires libsvn library as well, and JVM also fail to find libsvn location, but even apply above method, JavaHL still could not be loaded due to either "Could not find library" or "library has been loaded by another class loader"

Update 20/12/2008 - Forget about JavaHL!!! Use SVNKit which is purely bases on Java!!!
