I have a dll namely product.dll created using .net. How can i access that dll's constructor or method using java code.. Is it possible to access without using JNI?
In .NET you can achieve something like this:
Color yellowColor = Color.FromName("yellow");
Is there a way of doing this in Java without having to resort to reflection?
PS: I am not asking for alternative ways of storing/loading colors. I just want to know wherever it is possible to do this or not.
Hello
We are using sqllite056 jar in our code. While inserting into database in batch we are getting exception on line when we going to commit.
Lines of Code
<object of Connection> .commit();
<object of Connection>.setAutoCommit(true);
Exception
java.sql.SQLException: database locked
I need to determine the current state of the Shift key, but at the time I need the state I don't have an InputEvent object around. I need something like java.awt.Toolkit.getLockingKeyState(int) that works for Shift, not just the locking keys like VK_CAPS_LOCK. Is there a way I can do this without listening to input events and storing the for later when I need to check the state?
Thanks!
I would like to program Java servlets using Eclipse and I plan on deploying them using Tomcat. I think I can build the projects using Ant which is bundled with Eclipse. I have the standard Eclipse IDE. What options do I have for doing Servlet development in Eclipse? What changes do I need to make to Eclipse? Do I need to install a plug-in?
Does anyone overload the equals method in java? The overloaded method will be
public boolean equals(final MyClass myClass)
This will have the benefit of having the relevant comparison part (guts of the method) in another method.
Details are in this blog.

Need: Output a Java application's log into a GUI component, such as a JTextArea.

What should I do?
Is it possible to write objects in Java to a binary file? The objects I want to write would be 2 arrays of String objects. The reason I want to do this is to save persistent data. If there is some easier way to do this let me know.
Thanks in advance!
Hi there,
is it possible to start a new thread in a different process in Java?
I mean, I'm running a specific process and main thread, issuing ProcessBuilder for creating a new process. Before start() method is invoked, one must provide the command to be run in another process. Is it possible to start a new thread in newly created process?
Thank you in advance for the reply.
Best regards.
Is there a multipart POST library out there that achieve the same effect of doing a POST from a html form? for example - upload a file programmingly in Java versus upload the file using a html form. And on the server side, it just blindly expect the request from client side to be a multipart POST request and parse out the data as appropriate.
Has anyone tried this?
specifically, I am trying to see if I can simulate the following with Java
The user creates a blob by submitting an HTML form that includes one or more file input fields. Your app sets blobstoreService.createUploadUrl() as the destination (action) of this form, passing the function a URL path of a handler in your app. When the user submits the form, the user's browser uploads the specified files directly to the Blobstore. The Blobstore rewrites the user's request and stores the uploaded file data, replacing the uploaded file data with one or more corresponding blob keys, then passes the rewritten request to the handler at the URL path you provided to blobstoreService.createUploadUrl(). This handler can do additional processing based on the blob key. Finally, the handler must return a headers-only, redirect response (301, 302, or 303), typically a browser redirect to another page indicating the status of the blob upload.
Set blobstoreService.createUploadUrl as the form action, passing the application path to load when the POST of the form is completed.
<body>
<form action="<%= blobstoreService.createUploadUrl("/upload") %>" method="post" enctype="multipart/form-data">
<input type="file" name="myFile">
<input type="submit" value="Submit">
</form>
</body>
Note that this is how the upload form would look if it were created as a JSP.
The form must include a file upload field, and the form's enctype must be set to multipart/form-data. When the user submits the form, the POST is handled by the Blobstore API, which creates the blob. The API also creates an info record for the blob and stores the record in the datastore, and passes the rewritten request to your app on the given path as a blob key.
In C# you can easily read all classes from a given assembly.
I'm looking for equivalent feature in Java. I need this to automatically bind EJB beans to my Guice Module.
I'm a .NET developer learning Java EE. These two concepts seem to serve the same exact purposes in either system.
So which framework gets credit for inventing them?
I want to build a web services client that takes wsdl link as the input and generates java classes. I know we can do this directly using Netbeans IDE where we provide the wsdl location during project setup. But I want the wsdl location to be provided when the client starts running. How do I do this?
Is there a simple way to have your "Service Layer" deployed separately from your web layer, so that I can reduce the number of times per week that I have to, package, build and deploy the entire WAR file?
I'm using Tomcat mostly, but I'm hoping for something more generic to Java web servers

Why is it that in Java, a superclass' protected members are inaccessible by an indirect subclass in a different package? I know that a direct subclass in a different package can access the superclass' protected members. I thought any subclass can access its inherited protected members.
I have seen that there are many books titled:
Build Ecommerce website in php
Build shopping carts in php or asp.net

Desired topics:
Basic forms with logins and registration
Building catalogue system
Building shopping cart
Building newsletters system
