Why file.mkdir is returning false? Google indicates that there could be several reasons (e.g. security, permissions, pathname, etc). My questions: How to find the exact reason of returning false? If security/permissions is a reason, then why is SecurityException not thrown? If security/permissions is a reason, then why is SecurityException NOT thrown (which is mentioned in javadoc)? A SecurityException is thrown when you don't have JVM-level permission to do something, not OS-level Is there a way to find the exact reason why of returning false? No, AFAIK. The only way to know would be to check

I've a dynamic web app in Eclipse that is using Tomcat as runtime environment. I cannot add Javadoc path Tomcat Servlet API: as appears, the edit button is always disabled! alt text http://filaty.com/i/1005/80306/tom.JPG In Package Explorer of your project go to Java Resources > Libraries . Rightclick servlet-api.jar , choose Properties and specify the source location there (the apache-tomcat-x.x.x-src.zip file). Another way is to just open any Servlet API class using Ctrl + Shift + T or by Ctrl +Click on any import/declaration in existing code and then click the Attach Source... button and

If I write <xmlElement> in a javadoc, it does not appear, because tags have special functions on formatting texts. How can I show this chars in a javadoc? Pavitar Singh You can use < for < and > for > . Recent versions of JavaDoc support {@literal A<B>C}; this outputs the content correctly (escaping the '<' and '>' in the generated HTML). See http://download.oracle.com/javase/1.5.0/docs/guide/javadoc/whatsnew-1.5.0.html Etienne Delavennat Considering XML is actual code, I believe XML snippets in Javadoc are better suited for the {@code A<B>C} tag rather than the {@literal A<B>C} tag. The {

I dislike the default Javadocs generated for me when I create a Class or methods, especially the @author variable, which is the current system username on my windows box. I would like to change it. Is this possible? VonC Check Preferences / Java / Code Style / Code Template Section Comment / Type You can replace the author tag by whatever value you need and it will have an effect on new generated classes. However, if the template is fine, but the value referenced buy the author tag is not, see this SO question : ${user} uses the value of the user.name environment variable; therefore, you can

When I use quick documentaion lookup (Ctrl+Q) on j2ee classes or annotations in IDEA I only get an empty javadoc. It only contains the basics like class name. How do I add the javadoc to the libs IDEA provides itself? Hugo Palma You can attach javadoc to any library you have configure in your module or project. Just access the project structure windows (File -> Project Structure) , then select "modules" and select the module that has the dependency you want to configure. Then select the "Dependencies" tab, select the dependency that's missing the javadoc and click "Edit". In the window that

Is it correct practice to add Javadoc comments in the interface and add non-Javadoc comments in the implementation? Most IDEs generate non-JavaDoc comments for implementations when you auto generate comments. Shouldn't the concrete method have the description? Uri For methods that are implementation only (not overrides), sure, why not, especially if they are public. If you have an overriding situation and you are going to replicate any text, then definitely not. Replication is a surefire way of causing discrepancies. As a result, users would have a different understanding of your method based

In the Java APIs I can see Javadoc comments for packages. How/where do I place Javadoc comments to document a package? As of 1.5 you can define a package-info.java file and provide a standard javadoc style comment for a package: com/foo/package-info.java: /** * com.foo is a group of bar utils for operating on foo things. */ package com.foo; //rest of the file is empty Language specification for packages sleske Until Java 1.4, you had to provide a HTML file package.html, as described in the other answers. Since Java 1.5 you can also provide a package-info.java , which contains a regular Javadoc
