Using Ant the project doesn't compile

PROBLEM


When using ant and deploying using OjDeploy the project doesn't compile and generates an empty JAR. Even when parameter nocompile=false.

SOLUTION


In this case, setting the flag nocompile to false is not enought. It is necessary to be sure that the parameter is not on this ojdeploy target.

Error in getting XML input stream: file after adding Business Rule

PROBLEM

After adding a Business Rule with service interface I got:

Error: Error in getting XML input stream: file:/D:/PATH/ing/xsd/this.xsd:  D:/PATH/ing/xsd/this.xsd (The system cannot find the path specified) among a great quantity of exceptions on the project when compiled.


SOLUTION

Check the WSDL for the service interface. It is pointing to a wrong location /ing/

Could not find registry for the application _JBOServiceRegistry

PROBLEM

When using  ADF-BCon your composites you have to specify the registry service used to registry the bc. So for that you have to provide on the reference the <app-name>__JBOServiceRegistry.

The application name can be found on the application deployment profile of the sdo project.

When running the composite, if you get "Could not find registry for the <aap-name>_JBOServiceRegistry"

SOLUTION

In your weblogic-application.xml of the SDO application, make sure you added the JBO listener:

<listener>
<listener-class>oracle.jbo.client.svc.ADFApplicationLifecycleListener</listener-class>
</listener>


Now you are able to register the application on JBO listener

SOLUTION

1.       Log to soainfra schema
2.       Check in BPM_CUBE_PROCESS for record with the PROCESSNAME equals to the process and STATUS = 1
3.       Change the status to -1 for all these records
4.       Redeploy

Events and sdo losing transactions

PROBLEM


When triggering composites using events and on this composite there are transation management over SDO's some transactions are not commited

SOLUTION


Be sure that the events have Consistency set to one and only one and no set on Run as Publisher.

Attaching policies using the configuration plan

It is possible to attach policies to composites or components on deployment time using configuration plans.

To do that:

<service name="bpelprocess1_client_ep">
<binding type="ws">
<attribute name="port">
<replace>http://xmlns.oracle.com/Application1/TEST_XDN_CONGIFPLAN/BPELProcess1#wsdl.endpoint(bpelprocess1_client_ep/BPELProcess1_pt)</replace>
</attribute>
<wsp:PolicyReference URI="oracle/wss_username_token_service_policy"
orawsp:category="security"
orawsp:status="enabled"/>
<wsp:PolicyReference URI="oracle/log_policy"
orawsp:category="management"
orawsp:status="enabled"/>
</binding>
</service>

General Configuration Plan mixing endpoints

PROBLEM:

While using global config plan, the deployer is mixing endpoints

SOLUTION

What makes the cfg_plan act like this was this entry on the file:

<!--Template repository path references-->
<reference name="*">
<property name="........
</reference>
<!-- // -->

With this entry I was trying to attribute to all references the same configuration.

To avoid the unexpected behaviour described put all referencing of this kind after all references included on the configuration file.

Why sometimes we needed to add dehydration point after reply

Reply handling

We normally think of reply as causing the response to be sent back to the client, and if the transaction was initiated by the BPEL service engine, then it would be committed as part of the reply. In most cases, this is an accurate description of the end result, but this is not actually what happens. When a reply is reached, the response message is marked as available for returning to the requestor, but it is not returned to the requestor. Instead the BPEL engine will continue to process activities until it reaches a dehydration point. On reaching the dehydration point, the current thread (which was also the requesting thread) will return the reply message to the requestor. Note that this results in a delay in the returning of the result to the requestor, and it also causes the transaction scope to extend past the reply activity.

XSL code erase empty nodes, trim spces and normalize strings

XSLT code snippet to trim all spaces, normalize strings and erase all empty nodes.

<xsl:template match="node()">
<xsl:if test="count(descendant::text()[string-length(normalize-space(.))>0]|@*)">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:if>
</xsl:template>

<xsl:template match="@*">
<xsl:copy/>
</xsl:template>

<xsl:template match="text()">
<xsl:value-of select="normalize-space(.)"/>
</xsl:template>

Deployment over different environments

Use ORAMDS for all XSD / WSDL files on the project (oramds:...) in all composite.xml and wrappers on location tag. Doing that you will garantee that you can deploy anywhere even when you don't have remote access to a environment. And in this way it is not necessary to change endpoints on composite.xml on compilation time (by script for instance)

then use configuration plans.

Deploying EJB using Worklist API




When deploying fro Jdev 11.1.1.4 I got the error:


[EJB:011023]An error occurred while reading the deployment descriptor. The error was:
oracle/bpel/services/workflow/task/model/Task.
[11:57:04 AM] Caused by: java.lang.NoClassDefFoundError: oracle/bpel/services/workflow/task/model/Task

Solution:

Be sure that you have a EJB JAR project deployment profile and a EAR Application Deployment Profile.

Add these library entry on weblogic-application.xml file accessible go on Application Resources view on Jdeveloper / descriptors / META-INF
