Hello,
I have developed an app that exposes rest methods.
One of them is to return an image:
@GET
@Path("/image")
@Produces({ "image/png", "image/jpg" })
public Response getImage(@QueryParam("pProperty") String pProperty,
@QueryParam("pWorkstationky") Integer pWorkstationky,
@QueryParam("pSourceId") String pSourceId,
@QueryParam("pMemoTyp") Integer pMemoTyp,
@QueryParam("pImageRECCDate") String pImageRECCDate) {
AppModuleImpl am = null;
am = AMConfiguration.getAppModuleImpl(METHOD\_NAME, /\*pSessionId\*/"PreSession");
(...)
byte\[\] imageByte =
am.getImageByteArray(sessionId, pSourceId, pMemoTyp);
/\* DEFINIR RESULTADO COM\*/
if (imageByte != null && imageByte != new byte\[0\]) {
result = Response.ok(new ByteArrayInputStream(imageByte)).build();
} else {
result = null;
}
(...)
} finally {
if (null != am) {
AMConfiguration.releaseAMContext();
} else {
AMConfiguration.resetADFContext();
}
}
return result;
}
The am functions (release, reset, getAppMod) are in a class:
public class AMConfiguration {
private static final String filesAMParametersDef = "model.am.AppModuleImpl";
private static final String filesAMconfig = "AppModuleLocal";
private static ADFContext currentADFContext = null;
private static ApplicationModule am = null;
public AMConfiguration() {
super();
}
public static AppModuleImpl getAppModuleImpl(String pContext, String pSessionId) {
currentADFContext = ADFContext.initADFContext(pContext, pSessionId, null, null);
am = Configuration.createRootApplicationModule(filesAMParametersDef, filesAMconfig);
return (AppModuleImpl) am;
}
public static void releaseAMContext() {
Configuration.releaseRootApplicationModule(am, false);
ADFContext.resetADFContext(currentADFContext);
}
public static void resetADFContext() {
ADFContext.resetADFContext(currentADFContext);
}
}
The above is needed because of context leaks errors that appeared in console log.
My bc4j is :
<?xml version="1.0" encoding="UTF-8" ?>
<!---->
<BC4JConfig xmlns="http://xmlns.oracle.com/bc4j/configuration" version="11.1">

\</AppModuleConfig>
</AppModuleConfigBag>
</BC4JConfig>
In jsff page i have 'n' images calling this ws directly in source :
\<af:image source="#{viewScope.reportParametersBean.reportImageUrl}"
id="imagePreview" inlineStyle="width: 500px; height: 750px;"/>
the bean is returning (each image has different inputParameters) e.g.: https://nextgen-wlui12c.conceptsoftware.eu:9075/NGFilesWS/resources/files/image?pWorkstationky=553&pProperty=ractest3&pMemoTyp=110&pSourceId=44062-074-0000000032
When i test with postman or paste the above in browser i get the image correctly.
Problem is in jsff most of times (e.g. 98%) i get no images at all.
checking the console log i have errors in release AM:

because this is about the am, i found a link (https://tompeez.wordpress.com/2011/07/08/jdev-always-test-your-app-with-applicationmodule-pooling-turned-off/ ) from @"Timo Hahn" to test disabling the pooling.

and both leave the datasource of weblogic with active connections:
The only way i found to make images work correct is to decrease the maximum capacity of connection pool configurations in weblogic console for the datasource to 1.
But that is not the fix i need.
Can someone suggest please?
Thanks and regards,
Carlos
