I have Eclipse on my desktop at home, and on my netbook.
I have a workplace on a thumb drive.
I'm quite new to Eclipse, so this may be trivial to old hands, but it is currently a blockade to me.
The design and source code windows have disappeared. Previously, I could switch between them.
On my screen, I see MyProject.java in the one and only window pane in Eclipse. The font is too small for me to read. Previously, I was able to choose the font and size of the contents. When I try to do that now, no effect occurs on the source code.
The "Design" window pane has totally disappeared. What did I do to make that happen ? How do I get it back ?
I spent ten minutes trying to search and guess the menu system and got nowhere.
What do I click in order to ?...
- Return the "Design" window pane to my environment so that I can click on it and do the graphical stuff.
- Return the source code window pane to my sight which responds to Window -> Preferences -> General -> Appearance -> Colors And Fonts -> (So that I can do the actual code stuff)
Thank you for helping a clueless guy.

It is a while since I used eclipse, but as I recall there were menu items to show the various windows. There are also a couple of icons at the top right (I think) which allow you to show different layouts for different situations: one for development, and another for run/debug. Take a look at [^] which may give some clues. They do use some odd terminology but it does make more sense as you get used to it.

Login failed for user: usually means that some credential is not valid. Check that your userid and password are both correct. Also check any server logs to see if there is more informarion on exactly what went wrong.

I cannot find any examples that would suggest that the spaces before and after the equals sign should be there.

How can i load a file into the JTextArea

Probably by reading the content, if necessary converting it into text, and copying it to the JTextxxx window. See The Java™ Tutorials[^] for suggestions and samples.

You were given the answer back in October. It hasn't changed in the last two months.

It's a way of trying to get the answer you want.

It is one of those good practices which you're asked to follow while writing your code because it makes a lot cleaner and concise code. This is similar as to why we programmers focus so much on indentation... Because whenever you're working on a big project chances are you may not be the only person working on it, so if someone else has to review your code it'll be a lot easier for him/her to get a reference as to where was each variable declared. Because you might be well aware of the haunting NullPointerException which just pops out of no where and can be really trick to negotiate if your code isn't clear.
Hope this helps. Cheers.

Yep, and very ideal for troubleshooting and finding possible errors.

If you are expecting someone to write the code for you, you are going to be disappointed.

I think no one will do this for you until you offer a payment.

I want to build a web crawler that will take a list of urls and search those urls for events happening. I want the crawler to pick up details such as address, image urls, description of event, title of event. And anything else that would be useful for sombody wanting to know about an event. I would like to write this program in java or nodejs. Doing this project quickly and simply is important.
I have checked out nutch the java framework, but I had a difficult time getting going with it quickly. I want my web crawler to be up and running by the end of the week, so the simplest quickest solution is important.
What frameworks should I use and/or what advice do you have to complete such a project?

Be prepared for years of work; what you are asking for is far beyond a few simple classes. You would need to read each url, break it down into all its different parts and somehow analyse the content to identify each event (whatever you mean by that). You would then need to follow links from the event to extract any other relevant details. Just take a look at a few websites and see how they advertise events, each one is different.

Thanks for the input. But there is a huge difference between a few simple classes and 'years of work'. I think that maybe my problem was not defined well. But mainly I was hoping to get advice for a simple, quick to setup webcrawler with nodejs or java. Like a framework or a tool or somthing. As mentinoed I checked out nutch, but it seems overkill. I am not trying to scrape the whole web and I dont want to have to type like 300 characters into a terminal to start it up. I want to define in the beginning maybe 5 urls to scrape in the beginning and slowly but surely add to that url list. Any helpfuls suggestions are appreciated!
