Java Embedding Weird XML Node Error

Question

Ok, I am going crazy. I have a java embedding node that takes a date string in, changes it to a different format and creates another date that contains the current time. if I run this in java to code run ok and there are no issues. At the end of the java I print out the string and they are exactly what I want. The thing that is going on is when I set the 2 string BPEL variables in the java embedding, when I try to reference them the 2nd time,I get a weird node object error. I get through the first pass ok. when I try to reference Test1 or Test2 on the 2nd pass I get the error below. Its like when I set the variable currentDB2UpdateDate and currentDB2CurrTimeDate it does something to them. Instead of setting it to just the string it seems to set it to some kind of object.
I have 3 steps here. Assign -> Java Embedding -> Assign.
Assign 1 => Initialize 2 String variables to X.
<code>
<assign name="Assign_2">
<copy>
<from expression="string('X')"/>
<to variable="currentDB2UpdateDate"/>
</copy>
<copy>
<from expression="string('X')"/>
<to variable="currentDB2CurrTimeDate"/>
</copy>
</assign>
</code>
Java Embedding =>
<code>
String currentFileDate = (String)getVariableData("currentFileDate");
String currentDate = "";
try
SimpleDateFormat sdfSource = new SimpleDateFormat("MM/dd/yyyy");
Date date = sdfSource.parse(currentFileDate);
SimpleDateFormat sdfDestination = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
currentFileDate = sdfDestination.format(date);
catch(ParseException pe)
System.out.println("Parse Exception : " + pe);
try
Calendar cal = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
currentDate = sdf.format(cal.getTime());
catch(Exception pe)
System.out.println("Parse Exception : " + pe);
System.out.println("currentFileDate : " + currentFileDate.toString());
System.out.println("currentDate : " + currentDate.toString());
setVariableData("currentDB2UpdateDate",currentFileDate);
setVariableData("currentDB2CurrTimeDate",currentDate);
</code>
Assign 3 =>
<code>
<assign name="Assign_1">
<copy>
<from variable="currentDB2UpdateDate"/>
<to variable="Test1"/>
</copy>
<copy>
<from variable="currentDB2CurrTimeDate"/>
<to variable="Test2"/>
</copy>
</assign>
</code>
<code>
<bpelFault><faultType>0</faultType><selectionFailure xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/"><part name="summary"><summary>Invalid to part type.
When performing the assign operation, the to node 2010-07-17 12:00:00 is invalid.
The node named in the error message was either null or an empty node set, and it was not an instance of org.w3c.Element.
Verify the node value at line number 819 is not null and is an instance of org.w3c.Element.
</summary></part></selectionFailure></bpelFault>
</code>
The 2nd pass to this throws the following error when trying to set Test1 and Test2 again... Its like it is setting the variable to an object and not just the string. I tried using toString() in the setVariable too and it didn't work. I don't get it.

Answer 1

I am also facing a similar issue.There is selection failure in assignment to local variable of BPEL .
PFB the logs :
parts: {{
summary=&amp;lt;summary&amp;gt;Invalid to part type.
When performing the assign operation, the to node false is invalid.
The node named in the error message was either null or an empty node set, and it was not an instance of org.w3c.Element.
Verify the node value at line number 3577 is not null and is an instance of org.w3c.Element.
&amp;lt;/summary&amp;gt;}
Here is the code:
<copy>
<from expression="xpath20:add-dayTimeDuration-to-dateTime($calculatednpexectime,'P200YT')"/>
<to variable="calculatednpexectime"/>
</copy>
It seems as if Oracle is not accepting the date format .
Is there some issue with local variables of new version of BPEL ??
