How to validate RID

[Former Member]

Hi,

Is it possible to check whether an RID is valid or nor, ie, the corresponding folder actually exists or not?

I am using th following code to get the RID:

String path = "/KM/"+"SAP IMPLEMENTATION PROJECTS/"+project+rs_prop.getString("folder");
RID rid=RID.getRID(path);

In the next line I want to check whether the RID path actually exists before proceeding further. How can this be done? I tried if(rid!=null). But it didnt work.

Please Help.

Thanks,

Das.

Hi Krishna

U can validate like this

ICollection folder = null;
folder =(ICollection) resourceFactory.getResource(
		RID.getRID(properties.getProperty("Folder")),
			resourceContext);
if(folder!=null){

}

Hi Bobu,

I have already tried this. But in our case since there are more than 30 folders which doesnt have a valid path, it is taking a lot of time to execute the line:

folder =(ICollection) resourceFactory.getResource(

RID.getRID(properties.getProperty("Folder")),

resourceContext);

Seems it is time consuming to try to get a resource which does not exist. Is there anything that can be done to validate the RID other than trying to access the resource and then checking its value?

Thanks,

Das.

A RID is valid independantly of whether the resource exists or not (just pointing out terminology).

I think the ResourceFactory also has a checkExistance method, but I doubt it makes a difference performance-wise.

Hi Krishna

Why dont u use resource iterator?

It will give u only valid resources.

and also u can use isCollection() method to validate whether its folder or file

IResourceFactory resourceFactory;
IResourceContext resourceContext;
IUser cmAdminUser = null;
try {
	cmAdminUser =
		WPUMFactory.getServiceUserFactory().getServiceUser(
			"cmadmin_service");
} catch (UserManagementException e) {
	// TODO Auto-generated catch block
		e.printStackTrace();
}
resourceFactory = ResourceFactory.getInstance();
resourceContext = new ResourceContext(cmAdminUser);
ICollection folder = null;
folder = (ICollection) resourceFactory.getResource(
		RID.getRID(properties.getProperty("/documents/Folder/")),
			resourceContext);
IResourceList resList = null;
try {
	resList = folder.getChildren();
} catch (AccessDeniedException e1) {
	// TODO Auto-generated catch block
		response.write(
			"You dont have enough permission!!!<br>"
				+ e1.getLocalizedMessage());
	e1.printStackTrace();
} catch (ResourceException e1) {
	// TODO Auto-generated catch block
		response.write(e1.getLocalizedMessage());
		e1.printStackTrace();
}

IResourceListIterator iter = resourceList.listIterator();
while (iter.hasNext()) {
	IResource tempres = iter.next();
		if (!tempres.isCollection()) {
        }
}

This may help u

Hi,

you have to check by getting the Collection under the RID:

bolean exists = false;
try  {
IResourceContext rContext = new ResourceContext(curUser);
IResource res = ResourceFactory.getInstance().getResource(rid, rContext);
if(res!=null) {
exists = true;
}
} catch (Exception e)  {
//...
}
