I need to create a webpage quite similar to Google's great Docs spreadsheet, but in my case I cannot use their's.
Also there is no need to have the full feature set of the Google Docs spreadsheet (which is really big!).
But my minimal feature set is:
- change, add, delete cells and content
- change of formats like color, size, font
- the functions sum(), avg(), count()
My preferred tools are JSP, tomcat, JQuery. The server representation does not matter and could be any of xml, text, database tables or s.th. else.
I am quite sure, that there are perfect open solutions out there - which I can use to start - to fit my requirements but my problem is to find them.
Searching for "Google spreadsheet alternative" did not work very well.
Any hint or link is appreciated.
Thank you.
Alex
Take a look at primefaces sheet. If you like jQuery and use JSP, you should consider learning JSF and use primefaces since primefaces already heavily uses jQuery, meaning if you have to personalize the behavior of its controls, you are already presented with a familiar interface.
Primefaces sheet seems to provide what you're looking for, which is to say, something similar to an excel sheet.

I am an experienced Java programmer, and Im trying to create a website with much of its content based on dynamic data from a database. The scope of the website is quite small with only about 5 webpage designs required ( although the user will see thousands of different pages generated from the data), but each page is quite complex.
I decided to go with plain old Java and Servlets as I understand this well, I also understand html and CSS so have no real difficultly generating the basic html pages from the data.
My problem lies with the addition of Javascript to improve the user interface. Ive tried using Javascript a few times over the years and always make very slow progress, if there is an off the shelf well documented solution such as a Jquery widget then I okay, but if I need to modify it or create custom Javascript I always get stuck.
Im looking for any alternative to writing pure Javascript. Im not looking at learning a new framewotk for the complete site, or for a way to abstract the html because I understand that and I don't really like deploying generated code that I didnt write.
But in the case of Javascript I would consider generated code, is there a tool that I could use to generate Javascript without writing Javascript that I could then reference from my webpages, or it impossible to consider Javascript and Html in isolation from each other.
Jeremy Ashkenas's public List of languages that compile to JS lists pretty many (~hundred) options.
The section for Java/JVM to JavaScript alone lists 15 choices.
Coffeescript is a language that generate Javascript. I haven`t used it, but friends that develop in Javascript have told me that Coffeescript is a nice tool.

Within my organization, we have maintained a sharepoint site to store a large amount of files related to previous/ongoing projects. These files can be word, pdf and ppt files. We are interesting to build a solution that have following functionalities
1) Advanced search, return a set of files that matches the keyword input by users. It is better to mark the returned files with some label (like using color) on the contents that are directly related to the search keyword.
2) Enable users to perform some types of analysis on the sharepoint site. Such as social network analysis of the person who are authors of some sharepoint files.
Are there any commercial software or open source library to fulfill these types of tasks?
This response is assuming you are using SharePoint 2010 or 2013.
Consider using faceted search. If you have an Enterprise cal you can easily set this up. The trick is making sure the metadata for the facets is available. This would obtain the search behavior your looking for, but not the interaction and tagging.
For this it would be best to create a custom solution, and leverage term sets in managed metadata. In SharePoint 2010 there is conditional formatting that you could use for color coding, however this is deprecated in 2013.
Hope those directions are helpful, but ultimately you are likely going to need to do a combination with custom code and event handlers.

I've been searching high and low for an up to date solution to this age old problem.
Long story short I want to take css + html -> pdf and do it in java.
I don't want to use an API as the data is sensitive. Googling provides me with countless sites/services that offer to do this but I'm looking for a stand alone tool and looking for one that will work nicely from my java server. I've found this awesome looking command line tool but it's a command line tool and spawning processes off a web server starts to get sketchy IMO (but I'm always willing to hear otherwise). Additionally flying saucer seems to be a standard choice, but I've heard mixed reviews.
Here is a 5 year old question on the subject, but I figure things have changed! Especially with all the work being done in the area of front end unit testing with dom manipulation I figure there might be some less than conventional solutions and I'm willing to hear them all!
Any help would be greatly appreciated.
You might try a combination CSSBox that converts HTML+CSS to SVG and then use for example Batik for creating your PDF as proposed for example here. FlyingSaucer could also do the job.
The choice depends on your further requirements. E.g. are you processing "street HTML" or well-formed documents? What about the pages in the resulting PDF? What about interactive elements in the HTML pages?
I mean the only way is to try at least some options practically and then you may ask more specific questions about some particular problems.

How to convert to PDF from my JSP/HTML file?.
I want to convert a particular part of my webpage to a PDF file. Is it possible?
Yes. Take a good look at booth Apache FOP and iText. No matter what you use, you'll probably have to do a little fiddling.
I used HTMLDoc a couple of years ago and had pretty good luck with it.
try wkhtmltopdf. It is a command line utility that can be provided an html file or web address and a save location for the pdf. Very easy to use and utilizes the same rendering engine as safari. Works MUCH better than many of the other parsers that I have used (that don't always support CSS and other advanced layout features.
Take a look at html2ps (Perl) or html2ps (PHP). However, none of the two is implemented in Java.
You might also want to read this article.
flying saucer library is the best one to use. It works on top of itext and makes the task of conversion very easy.

I'm not committed to any particular GUI tookit or anything - just needs to be Java based. I want to do simple syntax highlighting ( XML and XQuery ) inside editable text areas.
My only candidate so far is Swing's JTextPane, as it supports seems to support the styling of text, but I have no idea how to implement it in this context.
If a particular toolkit has something like this out of the box, that would be awesome, but I'm open to doing this by hand if need be.
JSyntaxPane handles XML and can be extended
http://code.google.com/p/jsyntaxpane/wiki/Using
Or, it should be possible to extract the NetBeans editor, but that would probably be more work...
[edit] btw, I got the XML info from here... it doesn't seem to mention it on the google code pages...
Jide software has a Syntax Highligher component. It is still in beta, but I think it supposed XML. I haven't used it myself, so I don't know how well it will do what you want.
Why not check out Ostermiller's Syntax Highlighter.
Here's a simple code editor demo
It still uses JTextPane though.
