Lotus Notes: Create Excel files with POI

admin — Mon, 24 Jan 2011 14:19:51 +0000

My colleague (Martin Meijer) asked me some time ago how to easy export data to Excel without installing Excel on the server. As a Java developer I know Apache POI project. There is some great progress on that project.

So I made a simple Java Agent that creates a simple Excel file and embed it as an attachment. First of all you need to download Apache POI.

Create a new Java Agent. Import the poi.jar as archive. Also import the dependencies commons-logging.jar and log4j.jar

Edit your JavaAgent.java

Take a look at this code and implement your own agent (our copy it if you’re too lazy to understand).

Past it where the comment is (Your code goes here).

// (Your code goes here)
Workbook wb = new HSSFWorkbook();
Sheet sheet = wb.createSheet("Sheet 1");
Row row = sheet.createRow(0);
row.createCell(0).setCellValue("Hello Lotus");
Document doc = agentContext.getCurrentDatabase().createDocument();

RichTextItem item = doc.createRichTextItem("item");
File tempFile = new File(doc.getNoteID());
FileOutputStream out = new FileOutputStream(tempFile);

wb.write(out);
out.close();

item.embedObject(EmbeddedObject.EMBED_ATTACHMENT, null, tempFile.getAbsolutePath(), "Excel.xls");
doc.save();

tempFile.delete();
getAgentOutput().println("Done!");

Make sure that you import the classes after you pasted the code. Press Ctrl+1 on the errors.

Get User-Agent string in XPages

There is an easy way to get in server-side javascript in a XPage the User-Agent string from the request header. You can use this also to get other headers in the request.

facesContext.getRequest().getRequestHeaderMap().get("User-Agent");

This returns:

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/533.4 (KHTML, like Gecko) Chrome/5.0.375.125 Safari/533.4

Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0)

Installing IBM Lotus Notes 8.5 on Ubuntu 64bits

Here is a small how-to install IBM Lotus Notes 8.5 on Ubuntu Jaunty 64 bits

Sometimes I need to bite my tongue and this is on of those occasions. The icon text on the workspace is still an issue even with the final code drop 12. To make sure I was not at fault I did a few things today to work around the issue. I deleted, moved, copies, restored every desktop*.dsk file to no avail. The last test was to install Notes 8.5 on a clean system. The only one I had available was a new 64Bit Ubuntu system I have installed. For those in the know, Ubuntu sever does not come with a GUI. The options are to install the server version and then install the desktop. I use a different approach. I installed the 64Bit Ultimate Edition 2.0 version and then simply installed the Server Kernel. Works brilliantly. Here are the hurdles you will have to overcome to run on a 64bit system.

Download Notes 8.5 for debian platforms and extract the files.

sudo dpkg -i –force-architecture ibm_lotus_notes-8.5.i586.deb

sudo dpkg -i –force-architecture ibm_lotus_activities-8.5.i586.deb

sudo dpkg -i –force-architecture ibm_lotus_cae-8.5.i586.deb

sudo dpkg -i –force-architecture ibm_lotus_sametime-8.5.i586.deb

sudo dpkg -i –force-architecture ibm_lotus_symphony-8.5.i586.deb

However, you will find that you would not be able to start Notes.

Install the requisite 32 bit libraries.

apt-get install ia32-libs

You need to download the extra 32 bit libraries first. Use Getlibs

http://ubuntuforums.org/showthread.php?t=474790

Once installed then issue this command.

getlibs -p libavahi-client3 libavahi-common3 libavahi-glib1 libbonoboui2-0 libcroco3 libdbus-1-3 libdbus-glib-1-2 libeel2-2 libgnome2-0 libgnomecanvas2-0 libgnome-keyring0 libgnome-menu2 libgnomeprint2.2-0 libgnomeprintui2.2-0 libgnomeui-0 libgnomevfs2-0 libgsf-1-114 libgsf-1-dev librsvg2-2 librsvg2-common libselinux1 libsepol1 libstartup-notification0 libxkbfile1 gtk2-engines-ubuntulooks gtk2-engines-murrine

Depending on how you did the install the icon would not have been created but all is not lost. Start a Terminal session and change to:

/opt/ibm/lotus/notes/framework/

Now enter

../notes

If you are lucky then a separate console will startup and ask you to accept the license agreement.

Because you are starting Notes from a Terminal session you will see how the process starts up and this will help with diagnostics. In any event I had to issue the command three times before Notes would start but I am pleased to say the blog entry is being typed from an Ubuntu 64 bit server so It does work. Time to bite my tongue again.

After you’ve done this there are some steps to make it almost perfect.

Fonts fix. Install ttf-xfree86-nonfree package (Thanks Bram!)

yum install ttf-xfree86-nonfree

Fix Open attachment option. You cannot open attachments from the browser (this has also been seen on 32 bits systems). To fix this remove openwith in the notes directory and make a symlink to gnome-open

rm /opt/ibm/lotus/notes/openwith
ln -s /usr/bin/gnome-open /opt/ibm/lotus/notes/openwith

And for the last, start notes with linux32. This fixes that last library issues. Browser works and Sametime.

cd /opt/ibm/lotus/notes
linux32 ./notes

This is tested on Jaunty 64bits
