Struts data-source problem


Web tier: servlets, JSP, Web frameworks: Struts data-source problem

  1. Struts data-source problem (5 messages)

    I can not solve this problem form more then one week:
    I am trying to create simple web application using Struts
    in JBuilder X.
    Here are the steps I am doing:
    1. Create new project
    2. Create new Web-App
    3. Create new JSP with simple submit form
    Now the application can be runned and everything is ok.
    4. Add new dataSource to struts-config.xml so it looks like this:

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "">
        <data-source key="dataSource" type="org.apache.struts.util.GenericDataSource">
          <set-property property="driverClassName" value="com.borland.datastore.jdbc.DataStoreDriver" />
          <set-property property="url" value="jdbc:borland:dslocal:C:\xjozo\test.jds" />
          <set-property property="username" value="jozo" />
          <set-property property="password" value="jozo" />

    And when I try to run the app noe it throws this an exception (see log below).
    These libraries I have in my WEB-INF\lib\:


    The file test.jds exists.

    Can anybody help me, I am realy out of any ideas.
    Here is the tomcat log:

    IS your JDBC connect string correct? I'd expect it to have unix style slashes:
  3. Struts data-source problem[ Go to top ]

    Thanx but I have the same exception with unix style slashes.
    IS your JDBC connect string correct? I'd expect it to have unix style slashes:jdbc:borland:dslocal:C:/xjozo/test.jds
  4. Struts data-source problem[ Go to top ]

    Actually looking at the stack it seems that the Struts Jar cannot be found. is it present in /WEB-INF/lib?
    Or Struts basically work fine, until you add this datasource instruction. If that's the case then check that the JDBC driver JAR is also available.
  5. Struts data-source problem[ Go to top ]

    struts.jar is present in WEB-INF/lib.
    Everything works fine until the data-source ia added.
    JDBC driver(com.borland.datastore.jdbc.DataStoreDriver)
    is in the WEB-INF/lib/jds.jar .

    Could it be some kind of versioning problem?

    If there is somebody here who owns JBuilder X,
    could he, please, try the same steps as me and write here the result?

    thank you

    Hi Daniela-

    I've had a lot of trouble getting the struts datasource feature to work. There is an easier way to make the data avilable to your application, since you are using Tomcat. You can add a JNDI entry in Tomcat for the JDBC datasource. This can be easily done using the Tomcat web-based admin tool. Then, you can use JNDI lookups and the Service Locator pattern to hide the lookup operations.
