How to call the graphics management interface of the Cloudscape database and related questions You are likely to be knocked into java com.cloudscape.tools.cView in the command line mode. What is the reason? First, you have to see if your JDK version is right, is it 1.3.1_02 or more or 1.4. Second, the key in the key, the original Sun's J2EE in J2EE is working under the Cloudscape4.0.0.6 he came with (I really don't know what SUN is doing something :)) This is a sentence on the IBM website. : The Java 2 SDK, Enterprise Edition v. 1.3.1 Includes Cloudscape 4.0.6 But incrudes a Version of CloudView Which Will NOT Function with the 4.0.6 system. So the comrade door will go to the next one!
Common mistakes: java.lang.ClassNotFoundException: COM.cloudscape.core.JDBCDriver English explanation: To "find" the missing driver, you need to add to the CLASSPATH the cloudscape jar files RmiJdbc.jar, cloudclient.jar and system / cloudscape. jar which are located under the directory% J2EE_HOME% / lib / cloudscape / So, under UNIX you should execute: setenv CLASSPATH:. $ J2EE_HOME / lib / cloudscape / system / cloudscape.jar: $ J2EE_HOME / lib / cloudscape / cloudclient.jar : $ J2EE_HOME / LIB / Cloudscape / Rmijdbc.jar
under Windows, you should add to CLASSPATH the following% J2EE_HOME% / lib / cloudscape / system / cloudscape.jar;% J2EE_HOME% / lib / cloudscape / cloudclient.jar;% J2EE_HOME% / lib / cloudscape / RmiJdbc.jar
If You Will, You Can Also Look at "Cloudscape" Command (Cloudscape.Bat Under Windows) What Jar Files It Adds To ITS ClassPath.
We'd like also to give you a hint regarding missing classes. If some class can not be loaded, even though it should be somewhere, this indicates that the class is not "visible" in classpath for a class loader. To find the class, you should inspect JAR files under lib directory of a Java environment by using "jar -tvf file.jar" or WinZip. For example, to find the driver under UNIX one should execute in the directory $ J2EE_HOME / lib / cloudscape / system / the following jar tvf cloudscape.jar | grep JDBCDriverIn particular, the driver class COM.cloudscape.core.JDBCDriver is packaged in% J2EE_HOME% / lib / cloudscape / system / cloudscape.jar (under UNIX in $ J2EE_HOME / lib / cloudscape / system / Cloudscape.jar)
Chinese explanation: The focus is set to rmijdbc.jar, CloudClient.jar and system / cloudscape.jar
A few attention:
1. Modify resource.properties, you need to restrained J2EE Server2. When using CloudView, the Cloudscape database must be turned off. After setting the database 3.Deploy modify the default SQL, the SQL name on the left side of the screen, SQL text appears on the right After the modification is completed, you must click on the SQL name on the left, which means it is updated. If you go directly to the SQL name, you will be chaotic. When I saw the buddies in front, I will press OK if I change it. Otherwise, I will not be chaotic. 5. I don't know how the Cloudscape database is, anyway, it is not adding in SQL in Oracle. "It will ignore cases. For example: select * from Employee WHERE EMPLOYEEID = '123' and Select * from Employee WHERE EMPLOYEEID = '123' is the same, but DEPLOY is "" ", so SELECT * from" Employee "Where" EmployeeID "= '123' will be different from the select * from" Employee "where" EmployeeID "= '123' is different. The previous friends say that the problem is estimated here. 4. Deploy is required after the end, otherwise enter the ID in JSP, point Submit is a whiteboard.
