How to get the fully qualified name of the type of a variable [message #30621]

Hi,

I have a piece of code which is similar to this

class A {
public String one;
}

when i try to use JDOM and get the contents of this java file what i get
the type of the variable one is "String", but what I expect is that it
should give me the fully qualified name of String (i.e.,)
"java.lang.String", coz i do some validation based on the fully qualified
name. Plz provide me the details how can i get the corresponding qualified
name.

This is the same case with the SuperClasses, for eg.,
package org;
public class A {
public String one;
}

package org;
public class B
extends A {
public String two;
}

when i try to get the SuperClass Name it gives me A and not org.A

When i try to get an IType it states that the IType object is not open.
When i try to perform any action on that it states that the corresponding
element does not exist.

I get the IType through ICompilationUnit.getType(TypeName)

The compilation unit is obtained from

JavaCore.createCompilationUnitFrom(IFile) method.

When i try the open method on ICompilationUnit it states that the element
does not exist.

does the IFile exist? call exists() on it
is it on the classpath of a Java project?

String fileName = \"c:\\A.java\";
Path path = new Path(fileName);
IFile file = FrontierSuitePlugin.getWorkspace().getRoot().getFile(path);
System.out.println(\"The existence of file is \" + file.exists());
ICompilationUnit compUnit = JavaCore.createCompilationUnitFrom(file);

This is how i got the handle to the file and the ICompilationUnit.

i think this cannot work (by looking at IContainer javadoc)
path should be relative to the container

Sorry

I had given a wrong code snippet, i made the path as relative using
path.makeRelative() method and passed on the same to the IFile even then i
get false for the existence

i don't know a lot about Paths
but i looked at the javadoc and i think
it still cannot work

put the file under a java project in the workspace
it must be one the classpath anyway fo you to be able to resolve anything in it

Hi Adam,

Thanx a lot for ur suggesstions. It worked out fine for me when i got the
IFile through the
ResourcesPlugin.getWorkspace().getRoot().getFileForLocation( path). When i
checked this IFile instance's existence it gave me true and proceded with
other operations. Then tried to resolve the type using IType's
resolveType() method and got the corresponding qualified name of the
respective types.

Once again I thank for ur valuable suggestions.
