应该是 <html:select property= "lesson ">
<html:option value= "1 "> A </html:option>
<html:option value= "2 "> B </html:option>
<html:option value= "3 "> C </html:option>
</html:select>
然后form中的lesson属性你初始化为某一值就可以了，比如lesson= "3 ";
------解决方案--------------------
先把控件画好，然后用JavaScript动态的给控件赋初值
<html:select property= "lesson ">
<html:option value= "1 "> A </html:option>
<html:option value= "2 "> B </html:option>
<html:option value= "3 "> C </html:option>
</html:select>
<SCRIPT LANGUAGE= "JavaScript ">
document.all.lesson.value= "1 ";
</SCRIPT>
