The following was originally posted by mswanson as FYI: great debugging solution in Sun's Java Web Start and JNLP forum, for JDK 1.4: I would like to let the JWS community know of a great way to debug your JWS app. Solutions have been posted before but I haven't seen anything as easy as this: JDK}/bin/java -Xdebug -Xnoagent -Djava.

There is a full set of APIs and tools that enable you to debug your Java application. Both local and remote debugging is supported. There are also APIs, tools and resources for observability, management and performance profiling. A good starting point for all these activities is the Java SE 5.0 Troubleshooting and Diagnostic Guide. See similar questions...

Java Web Start is an application launcher for Java applications that are written to be web-deployed. Java Web Start caches resources locally on the disk, but also provides a secure execution environment and a virtually transparent updating facility for applications. The end user does not need to manually initiate a software update because the application is updated each time it is used. See similar questions...

application must be delivered in a set of JAR files and all application resources, such as images, configuration files, and native libraries must be included in the JAR files. The resources must be looked up using the method ClassLoader.getResource() or an equivalent method. Java Web Start only transfers JAR files from the web server to the client.

You can start the example application in debug mode to debug your java class with your favorite IDE (like eclipse). java -Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n -jar start.jar More Actions: Show Raw Text Show Print View Delete Cache -------- Attachments Check Spelling Show Like Pages Show Local Site Map -------- Rename Page Delete Page See similar questions...

Here is a simple solution to debug your app under Web Start: C:\Program Files\JavaSoft\JRE\1.3.0_02\bin\javaw.exe -Xdebug -Dnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,address=8118 "-Djnlpx.home=C:\Program Files\Java Web Start" "-Djnlpx.heapsize=NULL,NULL" "-Djnlpx.jvm=C:\Program Files\JavaSoft\JRE\1.3.0_02\bin\javaw.exe" "-Djava.security.policy=file:C:\Program Files\Java Web Start/javaws.policy" "-DtrustProxy=true" -classpath "C:\Program Files\Java Web Start\javaws.

Java™ Web Start is a technology of Sun Microsystems to deploy Java™ Desktop applications via the internet, without installing (platform dependent) binaries. See also the getting started section. See similar questions...

The forrest.jvmargs property in the forrest.properties file can be used to start forrest in debug mode on a specific port. forrest.jvmargs=-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n See similar questions...

Really with any .NET debugger, but there are a few things you might want to know about proxy objects to help you interpret what you're looking at. See similar questions...

Sometimes you just don't know why a Java function is returning the value it is returning. This page tells you how you can debug into the Java parts of the application. See similar questions...

If your application is written to the Java 2 platform, and is delivered as a set of JAR files, there should be no need to revise your application. Make sure that your application retrieves all its resources (such as images and resource bundles) from a JAR file, since Java Web Start launches an application by invoking the public static void main(String[] args) method. See similar questions...

You can use Java Web Start to deploy Java Technology-based applications that depend on native code such as DLLs and SOs. Use the <nativelib ...> element to specify required native libraries. See the Developer's Guide for details. Java Web Start uses a user-level classloader to load all the application resources specified in the JNLP file. This classloader implements the security model and the downloading model defined by the JNLP specification. See similar questions...

Java Web Start provides a platform-independent, secure, and robust deployment technology. It enables developers to deploy full-featured applications to end-users by making the applications available on a standard web server. With any web browser, end-users can launch the applications and be confident they always have the most-recent version. See similar questions...

Any client system that supports the Java version 1.2.2 or higher can use Java Web Start. Java Web Start works with virtually all browsers. See similar questions...

The underlying technology for Java Web Start, the Java Network Launching Protocol and API is being developed through the Java Community Process, so you can implement this protocol in any product. However additional licensing and terms must be met to implement any JCP technology including the JNLP technology. See similar questions...

Security is a key consideration of the Java Web Start design. In Java Web Start all applications are launched by default in a secure "sandbox." See similar questions...
