[jira] Resolved: (TUSCANY-1198) ClassCastException when getting
back a type extended from anything besides a string
[ https://issues.apache.org/jira/browse/TUSCANY-1198?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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?

> 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.
