When I was doing JSP/Servlet programming, whenever I dropped 3rd party libraries into the WEB-INF/lib folder, they were automatically included in the project classpath. In GWT, this is not the case. Anyone know why? I loved how easy this was in JSP and I'd like these jars to be included automatically the same way. ...
My applet runs file when I call it from a static applet.html file, like this: <applet archive="applet.jar" code="com.xxx.yyy.PApplet" width="100" height="20"></applet> But how do I put the same line in a django template? And where should I put the .jar and .java files? I also noticed that it appends .class to the PApplet while lo...
In eclipse, when using an external jar (SuperCSV in particular) I get an error which reads: "variable references non-existent resource". The build path has the Jar added to it and does not display any errors until run. Also the error seems to only occur when java RMI is used (commenting out the RMI code allows the code to run, just witho...
Is it possible to create a JAR file that requires external dependencies without including those dependencies in the JAR file? My google-fu has failed to give me an answer; everything that I have found shows how to include them in the JAR file, but not what to put in the manifest file to say "I haven't got them, look in the user's class...
Is there a way I can include pre-generated JavaDoc in a JAR file and have Eclipse 3.5+ automatically associate this with the contained classes? I know it's possible to manually set-up an association after the JAR has been added using the Eclipse GUI, but I'm wondering if there is, for example, something I can put in a manifest file so t...

Hi everybody, i am trying to use a container managed datasource (via context.xml) in tomcat. The corresponding jar file needs to go in $catalina_home/lib, otherwise tomcat can't find it. (not in webapp/WEB-INF/lib, because it is managed by the webserver, not by the application itself) the problem is: I am using maven with the maven-to...
Is there a way to add a dynamic library folder to a plain Java project similar to WEB-INF/lib in a Dynamic Web Project? I mean, can I specify a simple folder, let's just call it lib, and have Eclipse monitor it for any library jars I might want to add or remove. Currently I only know this behaviour from the Web App Libraries where any ...
If the lib/ directory contains only .jar files, what's the difference between java -cp "lib/*" ... and java -cp "lib/*.jar" ... If I use the latter I ran into errors regarding main class and I don't understand why. lib/* also contains lib/., but is this the crucial difference? ...

I have a core JAR that provides some functionality and hence used in lots of other apps as well - desktop apps, web apps etc. Now this core JAR maintains an object pool containing objects that are computationally expensive to create. The object pool is of fixed size and hence I create all of the objects at once and populate the pool. Wha...

Now the problem I am facing is that when I selected export in eclipse to export...

I have a .jar file which is 1MB. Without debug info, it should be about 100KB. Now, how do I strip the debug info? Oldtimers from the borland world might remember of a tool called tdstrip which would remove the symbol info from an .exe. What is the equivalent in the Java world? I'm trying to do mobile development where a 1MB file is wa...
I would like to have a Java application which can be easily started. So far I have managed to create a jar file but I do not see any advantages yet.

I have several J2EE projects using servlets, each of which extends from a base class that handles the main doGet and doPost methods and calls more specific methods on the subclasses. Rather than have that base class as a class in each WAR file, I want to move it to its own JAR that each of the other projects can reference. I'm using Ec...
