[jira] Created: (TUSCANY-1198) ClassCastException when getting back
a type extended from anything besides a string
ClassCastException when getting back a type extended from anything besides a string
-----------------------------------------------------------------------------------
Key: TUSCANY-1198
URL: https://issues.apache.org/jira/browse/TUSCANY-1198
Project: Tuscany
Issue Type: Bug
Components: Java SDO Implementation
Affects Versions: Java-M2
Environment: Apache Tomcat 5.5.17
Reporter: Sunny Ip
In my client code (calling from a JSP), whenever I am expecting a return type that extends anything but a string (tried so far with boolean, int, double, decimal, long), I get the following:
java.lang.ClassCastException: java.lang.String
$Proxy34.getAccountBalance(Unknown Source)
com.bns.references.account.client.AccountClientImpl.getAccountBalance(AccountClientImpl.java:14)
org.apache.jsp.AccountClientTest_jsp._jspService(AccountClientTest_jsp.java:81)
org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:332)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
org.apache.tuscany.runtime.webapp.TuscanyFilter.doFilter(TuscanyFilter.java:58)
Here is a snippet from a WSDL file that is being used:
<xs:schema xmlns:sample="http://sample" targetNamespace="http://sample">
<xsd:element name="getAccountBalance">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="accountNumber" type="sample:AccountNumber" />
</xs:sequence>
</xsd:complexType>
</xsd:element>
<xsd:element name="getAccountBalanceResponse">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="return" type="sample:Dollars" />
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:simpleType name="Dollars">
<xsd:restriction base="xsd:double">
<xsd:minInclusive value="0" />
</xsd:restriction>
</xsd:simpleType>
</xsd:schema>
with everything else exactly the same, changing the return type for getAccountBalanceResponse from "sample:Dollars" to "xsd:double" makes everything work fine. However, I need to be able to handle these kinds of extensions.

[jira] Commented: (TUSCANY-1198) ClassCastException when getting

Frank Budinsky commented on TUSCANY-1198:
-----------------------------------------
Another thought ... getting String values is often an indication that the metadata isn't available at runtime, so it could be that the SDO metadata hasn't been registered in the application's context.

[jira] Resolved: (TUSCANY-1198) ClassCastException when getting
back a type extended from anything besides a string
Posted by "Frank Budinsky (JIRA)" <tu...@ws.apache.org>.

Frank Budinsky resolved TUSCANY-1198.
-------------------------------------
Resolution: Cannot Reproduce
I generated the SDO interfaces using the attached wsdl file, and the getAccountBalanceResponse interface contains:
double getReturn();
void setReturn(double value);
Exactly the same as if xs:double was used as the type, instead of sample:Dollars.
Since the SDO part is working as expected, perhaps this is some kind of SCA proxy problem?
