[JBoss Seam] - Re: iText (PDF) support in Seam
by norman.richards＠jboss.com
You want the CLIENT to sign the PDF? That doesn't really make sense to me - you'll have to explain a bit more. Why wouldn't the user just download the PDF and sign it with his tools? (we could support leaving a blank signature field for that) If the users signature is to have any validity, the user should not be sending his private key across to the server to remotely sign something. I definitely need some convincing here.
On the keystore location, the normal practice in JBoss for any key usage is to have the keystore in the conf directory. It seems to have worked well for all uses of keys in JBoss so far. I need to move the keystore configuration out of view file and into a separate component, but other than that I'm very comfortable with the keystore choices. (well, I would also like to give the option of using a JBoss security domain to completely externalize the configuration)

[JBoss jBPM] - Timer Problem
by colsona
I deployed the attached process definition an ran it usin the attached JobQueueBean. The process executes to the wait state and appears to create the timer. I found that the timer never fired. In step tracing the timer creation I found the following methid in the Jboss source:
public void createTimer(Timer timer) {
// this wont work cause the process instance is not yet saved
schedulerSession.saveTimer(timer);
}
I also found the timer service wasn't deployed by default. I changed our app startup bean to create the timer service and confirmed it was running. It was unable to find any timers in the database which is needed for proper timer operation. We checked the DB tables ourselves and found that it was empty. We need to know if this is a defect which we need to get resolved immediately or if we have configured wrong and need to reconfigure.
The process definition:
| <?xml version="1.0" encoding="UTF-8"?>
| <process-definition
| xmlns="urn:jbpm.org:jpdl-3.1" name="FileEvent">
| <start-state name="start">
| <transition name="" to="Is file complete"></transition>
| </start-state>
| <decision name="Is file complete">
| <handler class="com.spss.batch.queue.handlers.CheckFileComplete"/>
| <transition name="true" to="Start job process"/>
| <transition name="false" to="false"></transition>
| </decision>
| <state name="false">
| <timer duedate="10 seconds" name="Wait For File" repeat="false" transition="Is file complete">
| <action class="com.spss.batch.queue.actions.FileEventTimerAction"/>
| </timer>
| <transition name="File isn't complete" to="Is file complete"></transition>
| </state>
| <node name="Start job process">
| <event type="node-enter">
| <action class="com.spss.batch.queue.actions.StartJobProcess"></action>

[JBoss jBPM] - Process variable class cast exception after signal()
by jglan
I have a process running fine until it reaches wait-state.
Each action node gets and sets some process variable without any problem.
The next action node (after the wait-state) throws class cast exception when attempting to get the same process variable (which was no problem in the nodes before the wait-state)
Is there any problem known in this area ?
I use a lot JMS i.e. the signal is send from some JMS thread via calling some SLSB.
I use jbpm 3.1.2

After sending the signal the same steps (getting the variable) gives the following:
the class returned from context.getContextInstance().getVariable has changed and obviously cannot be cast to the type expected (which was working before).
Also getContextInstance().getId() now has a value > 0 for some reason...

[JBossWS] - enumerations in jboss ws...
by mwiles
I have an xsd which has an enumeration type:
<xsd:simpleType name="IncomeTypeEnum">
<xsd:restriction base="xsd:string">
<xsd:enumeration value="pension" id="pension"/>
<xsd:enumeration value="salary" />
</xsd:restriction>
</xsd:simpleType>
The mapping snippet for that enum looks like this:
<java-xml-type-mapping>
<java-type>za.co.sanlam.employeebenefits.IncomeTypeEnum</java-type>
<root-type-qname xmlns:rtq="http://sanlam.co.za/employeebenefits/dto/1">rtq:IncomeTypeEnum</root-type-qname>
<qname-scope>simpleType</qname-scope>
<variable-mapping>
<java-variable-name>pension</java-variable-name>
<xml-element-name>pension</xml-element-name>
</variable-mapping>
<variable-mapping>
<java-variable-name>salary</java-variable-name>
<xml-element-name>salary</xml-element-name>
</variable-mapping>
</java-xml-type-mapping>
But when I deploy the web service I get the following error:
19:10:45,359 ERROR [MainDeployer] Could not start deployment: file:/C:/usr/jboss-4.0.5.GA/server/default/tmp/deploy/tmp50100EAR.ear-contents/EJB.jar

Has anyone done enumerations with jboss and could shed some light on what is going on? I
The java code for the enumration is as follows...
It does not seem as this is the problem as if I remove the java class, the error persists.
public class IncomeTypeEnum {
private java.lang.String _value_;
private static java.util.HashMap _table_ = new java.util.HashMap();
// Constructor
protected IncomeTypeEnum(java.lang.String value) {
_value_ = value;
_table_.put(_value_,this);
};
public static final java.lang.String _pension = "pension";
public static final java.lang.String _salary = "salary";
public static final IncomeTypeEnum pension = new IncomeTypeEnum(_pension);
public static final IncomeTypeEnum salary = new IncomeTypeEnum(_salary);
public java.lang.String getValue() { return _value_;}
public static IncomeTypeEnum fromValue(java.lang.String value)
throws java.lang.IllegalArgumentException {
IncomeTypeEnum enum = (IncomeTypeEnum)
_table_.get(value);
if (enum==null) throw new java.lang.IllegalArgumentException();
return enum;
}
public static IncomeTypeEnum fromString(java.lang.String value)
throws java.lang.IllegalArgumentException {
return fromValue(value);
}
public boolean equals(java.lang.Object obj) {return (obj == this);}
public int hashCode() { return toString().hashCode();}
public java.lang.String toString() { return _value_;}
}
I've tried everything to find the answer to my problem but just can't get anything. Hopefully it's quite a simple solution.
