The next search for ‘freq’ brings us into the list:
Search two
out.write(""+getFreq()+"\n");
This is where the list of QSO’s are displayed, using Java functions
to obtain the actual values, so we have to create those as well.
Add to this the following:
out.write("" +getRstTX()+"\n");
out.write("" +getRstRX()+"\n");
out.write(""+getName()+"\n");
out.write("" +getQTH() +"\n");
out.write("" +getLoc() +"\n");
out.write(""+getDist()+"\n");
Code sample 20
The class names are the same as for the headers, so it should
line up nicely. The ‘out.write()’ is necessary because this is inside
a java section, rather than straight HTML. Java generates the
HTML and writes it out.
Further with the search, we come to the section:
Search five
.freq { width:50px;}
For this we have to think carefully how big each field should be.
It should all fit on the window, so they can’t be too big.
Here are some reasonable values, but you could experiment a
bit with different values. Note that there is just one entry for rst,
as both RX and TX will be the same width.
Add the following:
.rst { width:40px;}
.name { width:80px;}
.qth { width:100px;}
.loc { width:60px;}
.dist { width:60px;}
.dxcc { width:100px;}

Next search: in the of the table we find:
Search three
This is where the new inputs take place.
Code sample 21
Later we will create a distance calculator for the locator which
wants it to be in uppercase, so just like with the callsign we use
the JavaScript event ‘onblur’ (mouse moving out of this field) to
call the toUpper() function and make sure the locator is uppercased.
The next search brings us into the Java-only section:
Search six (the final search!)
Freq
String getFreq() { return onerecord.get("freq"); }
The ‘class’ is the name we set in the CSS above, so that all becomes:
rstTX
rstRX
Name
QTH
Locator
Dist
DXCC
Next in the search:
Search four
Code sample 19
Here we set the functions that we can call from within the HTML
table to set the QSO data. They return the values found in the
XML database.
String getRstRX() { return onerecord.get("rstTX"); }
String getRstTX() { return onerecord.get("rstRX"); }
String getQTH() { return onerecord.get("name"); }
String getName() { return onerecord.get("qth"); }
String getLoc() { return onerecord.get("loc"); }
String getDist() { return onerecord.get("dist"); }
String getDxcc() { return onerecord.get("dxcc"); }
