I am working on a small team of web application developers. We edit JSPs in Eclipse on our own machines and then move them over to a shared application server to test the changes. I have an Ant script that will take ALL the JSPs on my machine and move them over to the application server, but will only overwrite JSPs if the ones on my m...
Hello,
I have done this on Websphere (re: title of this topic) using wsdl2java for generating wsdl to java mapping xml file.

Can anyone help?

Hello.
I'm writing an HTTP Cache library for Java, and I'm trying to use that library in the same application which is started twice. I want to be able to share the cache between those instances.
What is the best solution for this? I also want to be able to write to that same storage, and it should be available for both instances.

Hi,
I've been trying to build a simple prototype application in Django, and am reaching the point of giving up, sadly, as it's just too complicated (I know it would be worth it in the long-run, but I really just don't have enough time available -- I need something up and running in a few days). So, I'm now thinking of going with PHP ins...

Here's the deal. I have a hash map containing data I call "program codes", it lives in an object, like so:
Class Metadata
{
private HashMap validProgramCodes;
public HashMap getValidProgramCodes() { return validProgramCodes; }
public void setValidProgramCodes(HashMap h) { validProgramCodes = h; }
}
I have lots and lots of...
I have a third-party library in my SVN repository and I'd like to associate source/javadoc with it locally in Eclipse. I.e., there should be some local setting (for example, an entry in the local.properties file) that associates the source/javadoc with the JAR file, but which doesn't introduce local dependencies into the repository via ....
I have a process that runs on a UNIX (Solaris) server that runs nightly and needs to be able to send out encrypted emails.
I only need the "encryption" portion, NOT the digital signature / self-repudiation part of PKI.
I use MS Outlook in a corporate setting and I am assuming that when a user clicks "Publish to GAL..." under Tools -> O...
Hi,
I have some Jasper reports which are displayed in HTML format. I would like the width of the columns in the HTML tables to automatically resize to fit the content of the widest cell (in that column), such that all the data is displayed.
Currently this does not happen because the HTML generated by Jasper specifies fixed widths for t...
I'm trying to implement paging using row-based limiting (for example: setFirstResult(5) and setMaxResults(10)) on a Hibernate Criteria query that has joins to other tables.
Understandably, data is getting cut off randomly; and the reason for that is explained here.
As a solution, the page suggests using a "second sql select" instead of...
From a Java program, I need to launch the default browser on a local HTML file, pointed to an anchor inside the file. In Java SE 6, the java.awt.Desktop.browse method will open the file, but will not honor the anchor, so something like the following opens the file at the top, but does not page the browser to the anchor:
Desktop.getDesk...

I have seen many apps that take instrument classes and take -javaagent as a param when loading also put a '-noverify' to the commad line.
The java doc says that noverify turns off the class verification.
However why would anyone want to turn off verification even if they are instrumenting classes?

We've used both JWebUnit and HttpUnit in the past to do functional tests of web applications. Both of them seem to have issues in handling javascript. We are not particularly interested in testing the javascript at this point, but JWebUnit and HttpUnit tests have broken since we added some small Ajax components (Dojo Date / Time pickers ...
