Hi,
When building ui components, it generates code from given wsdl using
WSDL2Java. However, it fails with following error
[java] java.io.IOException: Cannot run program "C:\Program
Files\Java\jdk1.6.0_13\jre\bin\java.exe": CreateProcess error=87, The

The reason is, the classpath is too long, and windows can have only limited
classpath. The corresponding ant task in pom.xml is as follows: (Note that,
I took components\gadgets\org.wso2.carbon.gadget.editor.ui as an example,
but most of the other *.ui components are also failing. )
<tasks>
<java
classname="org.apache.axis2.wsdl.WSDL2Java" fork="true">
<arg line="-uri
src/main/resources/GadgetEditorService/GadgetEditorService.wsdl -u -uw -o
target/generated-code
-p org.wso2.carbon.gadget.editor.ui
-ns2p
http://services.editor.gadget.carbon.wso2.org
=org.wso2.carbon.gadget.editor.ui.services,http://utils.extensi
ons.registry.carbon.wso2.org/xsd=org.wso2.carbon.gadget.editor.ui.beans.xsd,http://exceptions.core.registry.carbon.wso2.org/xsd=org.wso2.carbon.gadget
.editor.ui.exceptions.xsd"/>
<classpath
refid="maven.dependency.classpath"/>
<classpath
refid="maven.compile.classpath"/>
<classpath
refid="maven.runtime.classpath"/>
</java>
</tasks>
When we change the "fork" parameter to "false", it works correctly. However,
the WSDL and output directory are given relative to the component directory
and will work only if the fork="true". So, we can't build it from some other
location (e.g if the component is
"components\gadgets\org.wso2.carbon.gadget.editor.ui", we can build inside
this location, but the build will fail if we try to build from "components"
or "components\gadgets"). One possibility is giving absolute path for WSDL
and output directory.
Modifying it as follows works without any issue:
<tasks>
<java
classname="org.apache.axis2.wsdl.WSDL2Java">
<arg line="-uri
${project.basedir}/src/main/resources/GadgetEditorService/GadgetEditorService.wsdl
-u -uw -o ${pro
ject.basedir}/target/generated-code
-p org.wso2.carbon.gadget.editor.ui
-ns2p
http://services.editor.gadget.carbon.wso2.org
=org.wso2.carbon.gadget.editor.ui.services,http://utils.extensi
ons.registry.carbon.wso2.org/xsd=org.wso2.carbon.gadget.editor.ui.beans.xsd,http://exceptions.core.registry.carbon.wso2.org/xsd=org.wso2.carbon.gadget
.editor.ui.exceptions.xsd"/>
<classpath
refid="maven.dependency.classpath"/>
<classpath
refid="maven.compile.classpath"/>
<classpath
refid="maven.runtime.classpath"/>
</java>
</tasks>
Is it ok to change as above? Any problem in above approach? Please give your
comments.
Regards,
Shankar
