我的mysql的怎么ctrl+c用不了,我也看了,设置里的快捷键没问题呀我的mysql的怎么ctrl+c用不了,我也看了,设置里的快捷键没问题呀

jsp能用连接池,为什么 java的就不能用呢 ================================================================================

测试的java类就得不连接而用jsp就可以同一个项目下的呀

1234123412341234这是怎么回事

jsp可以得到连接 ,而java的类就得不到哟, tomcat数据源

jsp可以得到连接 ,而java的类就得不到哟,,,,,陪有高清图片

谁能帮我看看这是什么回事, 测试的java类就得不连接而用jsp就可以同一个项目下的呀

mysql数据源的问题,求助用myeclipse运行在测试的一个类里就得到连接对像,项目的lib里上加了mysql的驱动的了可是用jsp用手工运行的话就是个错误,mysql的驱动弄到环境变量里了, 还是是500这个一个错误 (不过我用oracle的时候就不问题,就是在用mysql就完了) mysql的驱动已经放在tomcat的conf/lib里了大家能帮忙看哪个方面还会有错吗,我去找找去

我的路径中怎么会出现了webroot这个

localhost:80/demo能访问,怎么把这个demo也去,也能访问, 我的意思是,输入IP:80端口就访问网站了,能不

好像是连接池错误请指教一下 message javax.servlet.ServletException: org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (调用中无效的参数)

有人见过这错误吗Cannot create PoolableConnectionFactory (调… Cannot create PoolableConnectionFactory (调用中无效的参数)

Cannot create PoolableConnectionFactory 这是怎么回事连接池建不了,

看看有没有见过这个错误呀, HTTP Status 500 - javax.servlet.ServletException: org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (调用中无效的参数) 我正学tomcat数据源呢,怎么出个servlet错误呀

tomcat的数据怎么会出了个servlet的错呀,

tomcat数据源,出错了, 错误信息,呵呵,这是不是出的是servlet的错误呆, 这数据源还和servlet有著不解之源吗,呵呵 org.apache.jasper.JasperException: An exception occurred processing JSP page /JNDI.jsp at line 8 5: String JNDINAME = "java:comp/env/jdbc/oracle" ; 6: Context ctx = new InitialContext() ; 7: DataSource ds = (DataSource)ctx.lookup(JNDINAME) ; 8: Connection conn = ds.getConnection() ; 9: %> 10: <%=conn%> 11: <% Stacktrace: org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:568) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:455) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:390) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:334) javax.servlet.http.HttpServlet.service(HttpServlet.java:728)

tomcat数据源的错误,应该是哪配置错了吧 HTTP Status 500 - An exception occurred processing JSP page /JNDI.jsp at line 8 type Exception report message An exception occurred processing JSP page /JNDI.jsp at line 8 description The server encountered an internal error that prevented it from fulfilling this request. exception org.apache.jasper.JasperException: An exception occurred processing JSP page /JNDI.jsp at line 8 5: String JNDINAME = "java:comp/env/jdbc/oracle" ; 6: Context ctx = new InitialContext() ; 7: DataSource ds = (DataSource)ctx.lookup(JNDINAME) ; 8: Connection conn = ds.getConnection() ; 9: %> 10: <%=conn%> 11: <% Stacktrace: org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:568) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:455) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:390) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:334) javax.servlet.http.HttpServlet.service(HttpServlet.java:728) root cause javax.servlet.ServletException: org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (调用中无效的参数) org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:912) org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:841) org.apache.jsp.JNDI_jsp._jspService(JNDI_jsp.java:87) org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70) javax.servlet.http.HttpServlet.service(HttpServlet.java:728) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:432) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:390) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:334) javax.servlet.http.HttpServlet.service(HttpServlet.java:728) root cause org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (调用中无效的参数) org.apache.tomcat.dbcp.dbcp.BasicDataSource.createPoolableConnectionFactory(BasicDataSource.java:1549) org.apache.tomcat.dbcp.dbcp.BasicDataSource.createDataSource(BasicDataSource.java:1388) org.apache.tomcat.dbcp.dbcp.BasicDataSource.getConnection(BasicDataSource.java:1044) org.apache.jsp.JNDI_jsp._jspService(JNDI_jsp.java:72) org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70) javax.servlet.http.HttpServlet.service(HttpServlet.java:728) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:432) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:390) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:334) javax.servlet.http.HttpServlet.service(HttpServlet.java:728) root cause java.sql.SQLException: 调用中无效的参数 oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:124) oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:161) oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:226) oracle.jdbc.driver.T4CConnection.logon(T4CConnection.java:196) oracle.jdbc.driver.PhysicalConnection.<init>(PhysicalConnection.java:343) oracle.jdbc.driver.T4CConnection.<init>(T4CConnection.java:147) oracle.jdbc.driver.T4CDriverExtension.getConnection(T4CDriverExtension.java:31) oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:545) org.apache.tomcat.dbcp.dbcp.DriverConnectionFactory.createConnection(DriverConnectionFactory.java:38) org.apache.tomcat.dbcp.dbcp.PoolableConnectionFactory.makeObject(PoolableConnectionFactory.java:582) org.apache.tomcat.dbcp.dbcp.BasicDataSource.validateConnectionFactory(BasicDataSource.java:1556) org.apache.tomcat.dbcp.dbcp.BasicDataSource.createPoolableConnectionFactory(BasicDataSource.java:1545) org.apache.tomcat.dbcp.dbcp.BasicDataSource.createDataSource(BasicDataSource.java:1388) org.apache.tomcat.dbcp.dbcp.BasicDataSource.getConnection(BasicDataSource.java:1044) org.apache.jsp.JNDI_jsp._jspService(JNDI_jsp.java:72) org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70) javax.servlet.http.HttpServlet.service(HttpServlet.java:728) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:432) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:390) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:334) javax.servlet.http.HttpServlet.service(HttpServlet.java:728) note The full stack trace of the root cause is available in the Apache Tomcat/7.0.35 logs.

有没有知道把win7的本改成无线的那个功能,我这怎么出错了

昨天看了一个可以让win7笔记本当无线的回家试试不行呀,以下错误看看有没有见过呀就在设置设置Internet连接共享：在“网络连接”窗口中，右键单击已连接到Internet的网络连接（这里是CMCC-EDU），选择“属性”→“共享”，勾上“允许其他······连接(N)”并选择“虚拟WIFI”。就出错了

再次发一个沉了贴关于servlet的404,上次问题形容不详细请大家给我点参考这个servlet的404都还有哪些方面是可能出错的地方,我现在找半天了,把老师提到的容易出错的地方都看了,应该问题不大,还有没有别的地方会出现404错误的这个servlet之前是可能通过,不知道怎么回事,这几天又不行: 看了web的路径好像没什么问题: 用我myeclipse做的: 文件都在D:\WEBDEMO\EmpProject\ demo是工作区,EmpProject是项目名称,IE访问路径:http://tieba.baidu.com/mo/q/checkurl?url=http%3A%2F%2Flocalhost%2FEmpProject%2Fjsp%2Fadmin%2Femp%2FEmpServlet&urlrefer=a35867d7729f4157fe81b324159b26e9 下面是代码: <servlet> <servlet-name>EmpServlet</servlet-name> <servlet-class>org.rn.oracle.servlet.EmpServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>EmpServlet</servlet-name> <url-pattern>/jsp/admin/emp/EmpServlet</url-pattern> </servlet-mapping> =============== package org.rn.oracle.servlet; import javax.servlet.*; import javax.servlet.http.*; public class EmpServlet extends HttpServlet { public void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException { this.doPost(request, response); } public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException { ........................................................... } } ========== 我用eclipse已经发布项目了 IE路径好像和web.xml里的是一样的吧 servlet有包,包.类名称和web.xml一样吧 servlet用的是public ,继承了HttpServlet,这个包也导入了请大家看看还有哪可能出错,

有人见过个错误吗 --->"'(<进行语法解析时已到达文件结尾>)'" cmd: E:\java>javac Noname1.javaNoname1.java:14: 进行语法解析时已到达文件结尾} ^1 错误 ============ java: import java.util.*; public class Noname1{ public static void main(String [] args){ String str[]={"zhangsan","lisi","wanger","zhaowu"}; System.out.println("比较前:"); for(int i=0; i<str.length; i++){ System.out.println(str[i]); } System.out.println("比较后:"); Arrays.sort(str); for(String s : str){ System.out.println(s); } } ================ 用myeclipse运行没错,

myeclipse能不能不用运行,把java的文件弄成class的呀在a类修改完一个方法 ,在b类调动的时候就找不到a类中的这个方法,有时候等一会就能用a类的方法了,是不是机子太慢

登录的servlet怎么有时候就404,有时候就能通过呀我昨天下午改了半天终于可以正常登录了, 可是今天一开机就出404了,代码没动,tomcat也启动了,myeclipse也发布了发现好几次,还以为是代码哪错了呢发现地址有时候这是样的http://tieba.baidu.com/mo/q/checkurl?url=http%3A%2F%2Flocalhost%2Fdemo%2FEmpProject%2FWebRoot%2Fjsp%2FTuserServlet&urlrefer=e61b6c14494880369ad7a7acea85aa4d 有时候是这样的http://tieba.baidu.com/mo/q/checkurl?url=http%3A%2F%2Flocalhost%2Fdemo%2FEmpProject%2Fjsp%2FTuserServlet&urlrefer=a4e86a273be6823854ad631822636a8d demo是myeclipse的工作区 EmpProject是建的工程吧

要是游戏加一个被击倒了,蹬腿的功能就无敌了,呵呵像cod让狗弄倒还可以近战呢

为什么破手枪都可以一枪爆头,,冲锋枪得两枪,威力有点太小了, 工程好鸡肋呀,
