We are using the struts with spring in a project.
Consider a simple action with **stream** result
@Action(value = "sample-export",
results = { @Result(name = "success", type = "stream", params = {
"inputName", "exportInputStream", "contentType",
"${exportContentType}; charset=UTF-8", "Content-Disposition",
"attachment; filename=\"${filename}\"", "contentDisposition",
"attachment; filename=\"${filename}\"", "bufferSize", "2048" }) })
public String export() throws ClientException {
//buildExportInputStream() creates and returns new
ByteArrayOutputStream by using jasper
exportInputStream = buildExportInputStream();
LOG.debug("Exporting to {} file ", getFilename());
return SUCCESS;
}
This works fine.
Some thing strange happens when I add below line in
`spring-applicaiton-context.xml` !!
<bean id="sampleStream" class="java.io.FileInputStream" >
<constructor-arg value="c:/sample.jks"/>
</bean>
After adding above line the inputStream of action will be a zero size file!
When I set a break point in **StreamResult**, **doExecute** method the
`inputStream.read(oBuff)` is always **-1**.
--------
The created bean (**sampleStream**) will be referenced by other beans by using
ref for example `<ref bean="sampleStream"/>`. When I change this structure and
use **sampleStream** as an inline parameter it works fine:
<bean id="anotherBean" class="foo.bar">
<bean class="org.xml.sax.InputSource">
<constructor-arg index="0" >
<bean class="java.io.FileInputStream">
<constructor-arg index="0" type="java.lang.String"
value="c:/sample.jks"/>
</bean>
</constructor-arg>
</bean>
</property>
</bean>
------------
Well can you help me to find what is going wrong ?! Why defining a bean of
`FileInputStream` will cause this happens ?!
