Injecting Service Error
Hi
I am trying to inject a service so that I preview images stored in a blob in
the database. I have the following code but it gives me an error that the
service can't be found when I view that particular page.
hivemodule.xml
--
contribution configuration-id=tapestry.url.ServiceEncoders
page-service-encoder id=page extension=html
service=page/
direct-service-encoder id=direct
stateless-extension=direct stateful-extension=sdirect/
/contribution
contribution configuration-id=tapestry.services.FactoryServices
service name=ImageService object=service:ImageService/
/contribution
service-point id=ImageService
interface=org.apache.tapestry.engine.IEngineService
invoke-factory
construct class=mypackagename.ImageService
set-object property=linkFactory
value=infrastructure:linkFactory/
/construct
/invoke-factory
/service-point
ImageService.java
-
public class ImageService
implements IEngineService
{
private LinkFactory linkFactory;
public ILink getLink(boolean isPost, Object parameters)
{
Object[] parameterArray = (Object[]) parameters;
Object reportId = parameterArray[0];
Map serviceParameters = new HashMap();
serviceParameters.put(ServiceConstants.SERVICE, getName());
serviceParameters.put(ServiceConstants.PARAMETER, new
Object[] {reportId});
return linkFactory.constructLink(this, isPost,
serviceParameters, true);
}
public String getName()
{
return ImageService;
}
public void service(IRequestCycle cycle)
throws IOException
{
// ...
}
/**
* @return Returns the linkFactory.
*/
public LinkFactory getLinkFactory()
{
return linkFactory;
}
/**
* @param linkFactory The linkFactory to set.
*/
public void setLinkFactory(LinkFactory linkFactory)
{
this.linkFactory = linkFactory;
}
}
And my java class for the page
--
@InjectObject(service:ImageService)
public abstract IEngineService getImageService();
The @InjectObject line throws the following error: Service point
tapestry.ImageService does not exist
What am I missing? I know my hivemodule.xml file is being read as the
friendly urls work fine.
I am including my stack trace:
-

RE: Injecting Service Error
For those who are curious, the fix is...
When calling the service I needed to prefix the applicationId as specified
in the hivemind.xml file e.g: @InjectObject(service: applicationId
.ImageService)
I was tearing my hair out with this one!!!
Thanks to those who tried to help.

Hi
I already had the following at the top of my hivemodule.xml file
module id=SAC version=1.0.0 package=org.apache.tapestry.workbench
And even if I change it to:
module id=SAC version=1.0.0
package=mypackagename.tapestry.ImageService
It still doesn't work - same error.
Btw, in my code below, my ImageService package actually is something like
mypackagename.tapestry.ImageService and not mypackagename.ImageService
so I thought that tapestry.ImageService was still then referring to my own
class.

Well, IMO HiveMind isn't able to find your ImageService service point
and defaults to tapestry.ImageService where it can't be found, too.
Try to put something like this in your hivemodule.xml
module id=your_application_id version=1.0.0
package=path.to.the.package.with.ImageService

OGNL in javascript
Hi All
I want to put an ognl expression in my onclick event of a link
e.g: onclick=ognl:'javascript: document.getElementById('userId').value=' +
user.Id
but the above doesn't work. I have tried various variations with no success.
I know onclick=ognl: user.Id would print out the id but I need to append
it to a string.
Can it be done?
Thanks,
Deon

You have to escape the ('userId'), like this probably: (\'userId\')

Error trying to implement Custom Exception Page
Hi All I have implemented a custom engine class extending BaseEngine so that I could override activateExceptionPage in order to have different error pages for development and production purposes. Inside my custom activateExceptionPage function I have the following code: cycle.activate(CustomException); renderResponse(cycle); to supposedly render my error page. However I am getting a blank html page when an exception does occur. I have set my application to use my engine class and it works fine if in activateExceptionPage() I just call super.activateExceptionPage(cycle, cause). I get the following error in my application log file: 2006-05-24 09:44:06,734 [http-8080-Processor24] WARN tapestry.error.RequestExceptionReporter - activateExceptionPage() Have I missed something?? Does anyone have any suggestions where I am going wrong here. Thanks, Deon - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
