<P>MyEclipse默认的应用服务器为JBoss3�Q�这里我们��用WebLogic8.1。启动Eclipse�Q�选择“窗口\首选项”菜单，打开首选项对话框。展开MyEclipse下的Application Servers�l�点�Q�点击JBoss 3�Q�选中右面的Disable单选按钮，停用JBoss 3。然后点击WebLogic 8�Q�选中双���的Enable单选按钮，启用WebLogic服务器。同时下面的配置如下�Q?<BR>(1)BEA home directory�Q�C:\BEA。假定WebLogic安装在D:\BEA文�g夹中�?<BR>(2)WebLogic installation directory�Q�C:\BEA\weblogic81�?<BR>(3)Admin username�Q�用户名�?<BR>(4)Admin password�Q�密码�?<BR>(5)Execution domain root�Q�安装后�Q�启动服务的路径�?<BR>(6)Execution domain name�Q�mydomain�?<BR>(7)Execution server name�Q�myserver�?<BR>(8)Hostname:PortNumber�Q�localhost:7001�?<BR>(9)Security policy file�Q�D:\BEA\weblogic81\server\lib\weblogic.policy�?<BR>(10)JAAS login configuration file�Q�省略�?<BR>以上配置�Ҏ��安装情况不同而不同�?BR>如图�Q?BR><IMG height=529 alt=myeclipse_weblogic.JPG src="http://www.aygfsteel.com/images/blogjava_net/shmily432685/subject/myeclipse_weblogic.JPG" width=759 border=0><BR>接着展开WebLogic 8�l�点�Q�点击JDK�Q�在双���的WLS JDK name处选择WebLogic 8的默认JDK。这里组合框中缺省�ؓj2re1.4.2_03�Q�即之前单独安装的jre。单击Add按钮�Q�弹出WebLogic &gt; Add JVM对话框，在JRE名称处随便输入一个名字，如jre1.4.1_02。然后在JRE�ȝ��录处选择WebLogic安装文�g夹中的JDK文�g夹，如D:\BEA\jdk141_02�Q�程序会自动填充Javadoc URL文本框和JRE�pȝ��库列表框。单�ȝ��定按钮关闭对话框。这时候就可以在WLS JDK name�l�合框中选择jre1.4.1_02了。之后还要在下面的Optional Java VM arguments�Q�如-ms64m -mx64m -Djava.library.path="D:/BEA/weblogic81/server/bin" -Dweblogic.management.discover=false -Dweblogic.ProductionModeEnabled=false <BR>最后点击Paths�Q�在双���的Prepend to classpath列表框中�Q�通过Add JAR/ZIP按钮�Q�加入D:\BEA\weblogic81\server\lib\weblogic.jar、D:\BEA\weblogic81\server\lib\webservices.jar。如果用到数据库�Q�还需把数据库的驱动类库加�q�来�Q�这里我们用WebLogic自带的SQL Server数据库驱动库D:\BEA\weblogic81\server\lib\mssqlserver4v65.jar�?<BR>��x���Q�MyEclipse中WebLogic8的配�|�工作就���完成了。下面可以看看在Eclipse中能否启动WebLogic了？自从安装了MyEclipse之后�Q�Eclipse工具栏中��׃��有一个Run/Stop Servers下拉按钮。点击该按钮的下拉部分，选择“WebLogic 8\Start”菜单，卛_��始启动WebLogic了。通过查看下面的控制台消息�Q�就可以知道启动是否成功�Q�或有什么异常发生。停止WebLogic可选择“WebLogic\Stop”菜�?/P><img src ="http://www.aygfsteel.com/shmily432685/aggbug/21511.html" width = "1" height = "1" /><br><br><div align=right><a style="text-decoration:none;" href="http://www.aygfsteel.com/shmily432685/" target="_blank">闉|��</a> 2005-11-26 16:11 <a href="http://www.aygfsteel.com/shmily432685/archive/2005/11/26/21511.html#Feedback" target="_blank" style="text-decoration:none;">发表评论</a></div>]]></description></item><item><title>web.xml规则�l�过整理�ȝ��如下�Q?/title><link>http://www.aygfsteel.com/shmily432685/archive/2005/11/11/19258.html</link><dc:creator>闉|��</dc:creator><author>闉|��</author><pubDate>Fri, 11 Nov 2005 02:29:00 GMT</pubDate><guid>http://www.aygfsteel.com/shmily432685/archive/2005/11/11/19258.html</guid><wfw:comment>http://www.aygfsteel.com/shmily432685/comments/19258.html</wfw:comment><comments>http://www.aygfsteel.com/shmily432685/archive/2005/11/11/19258.html#Feedback</comments><slash:comments>0</slash:comments><wfw:commentRss>http://www.aygfsteel.com/shmily432685/comments/commentRss/19258.html</wfw:commentRss><trackback:ping>http://www.aygfsteel.com/shmily432685/services/trackbacks/19258.html</trackback:ping><description><![CDATA[<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt"><SPAN style="FONT-SIZE: 11pt;
