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.
