[jira] Created: (TUSCANY-1199) 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-1199
URL: https://issues.apache.org/jira/browse/TUSCANY-1199
Project: Tuscany
Issue Type: Bug
Components: Java SCA Web App Runtime
Affects Versions: Java-M2
Environment: Apache Tomcat 5.5.17
Reporter: Sunny Ip
Originally posted under SDO Implementation, but it was suggested it may be an SCA proxy problem:
In my client code (originating 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 when I call my service:
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. I have attached the wsdl and scdl (client side) files for reference. To reproduce:
1) create/generate classes to implement and consume the service described by the wsdl
2) expose the service in your scdl
3) call the getAccountBalance operation
The crash will occur after the method on the service side is complete, but before the client gets a response.

[jira] Closed: (TUSCANY-1199) ClassCastException when getting back
a type extended from anything besides a string
Posted by "Sunny Ip (JIRA)" <tu...@ws.apache.org>.

Sunny Ip closed TUSCANY-1199.
-----------------------------
Resolution: Invalid
Didn't realize this was still open. We found that the generated factory was not referenced in the composite file using dbsdo:import.sdo. I believe this should no longer be an issue.
