[jira] Created: (AXIS2-1489) wsdl2java fires NullpointerException
when using anonymous complex type
wsdl2java fires NullpointerException when using anonymous complex type
----------------------------------------------------------------------
Key: AXIS2-1489
URL: http://issues.apache.org/jira/browse/AXIS2-1489
Project: Apache Axis 2.0 (Axis2)
Issue Type: Bug
Components: wsdl
Affects Versions: 1.0
Environment: Windows XP, jdk1.5.0_06-b05
Reporter: Herman
When I compile a WSDL that contains the following piece of xml:
<complexType name="transactionRecord">
<sequence>
<element name="documentRefnr" type="types:documentRefnr"/>
<element name="formType" type="types:formType"/>
<element name="accountDb" type="types:account"/>
<element name="accountCr" type="types:account"/>
<element name="amount" type="types:amount"/>
<element name="status" type="types:status"/>
<element name="error" type="types:error"/>
<element name="dateCreated" type="dateTime"/>
<element name="dateLastChange" type="dateTime"/>
</sequence>
</complexType>
[...]
<element name="TransactionData">
<complexType>
<sequence>
<element name="TransactionRecord" maxOccurs="unbounded" minOccurs="0" type="types:transactionRecord"/>
</sequence>
</complexType>
</element>
If I leave out the [name="TransactionRecord"] in the last element (so it becomes anonimous), I get the following NullPointerException:
org.apache.axis2.wsdl.codegen.CodeGenerationException: java.lang.RuntimeException: org.apache.axis2.schema.SchemaCompilationException: java.lang.NullPointerException

Exception in thread "main"
------------------------------------
It seems a general bug - if you use anonymous elements, you'll get a NullPointerException in the SchemaCompiler.
My advice: NEVER EVER allow NullPointerExceptions! You can't even see at what line of the WSDL the compiler failed.
It took me quite some time to find the cause of this problem...

[jira] Commented: (AXIS2-1489) wsdl2java fires NullpointerException

Herman commented on AXIS2-1489:
-------------------------------
PS. I opened this issue as major because I encountered NullpointerExceptions many times while trying axis2 (I'm a beginner on axis2).
To be honest, the wsdl2java tool seems not very stable/mature. Many times the compiler fails leaving the developer with no clue about why it failed. Please improve the output messages in case of failure.

[jira] Updated: (AXIS2-1489) wsdl2java fires NullpointerException
when using anonymous complex type
Posted by "Herman (JIRA)" <ji...@apache.org>.
[ http://issues.apache.org/jira/browse/AXIS2-1489?page=all ]
Herman updated AXIS2-1489:
--------------------------
Attachment: DocumentQueryService.wsdl
Compile the attached file (I use options "-d adb -uri wsdl\DocumentQueryService.wsdl -ss -g -sd -o wsdl\output -p giroflow.docquery").
It will work.
Now edit the file and remove the [name="LEAVE_OUT_TO_GET_BUG"] part.
Compile again.
You'll get a NullpointerException
