  1. In the Enterprise Designer, right-click on the project, select Import. From the submenu, select File. The Import File dialog box appears.

  2. From


     <Client_eDesigner>\usrdir\modules\ext\oracleadapter, create a copy of the
 ojdbc14.jar
 in the directory and rename it
 classes12.jar
.

  3. Navigate to the classes12.jar file,


     <Client_eDesigner>\usrdir\modules\ext\oracleadapter\
classes12.jar
 using the Enterprise Designer’s Project File Import feature (see

    Using CLOBs

    Select class12 JAR file

  4. Click Select.

  5. Click Import. The classes12.jar file appears, as shown in Using CLOBs.

  6. To load the classes12.jar file into your Java Collaboration, select the Import JAR File button. Click Add in the Add/Remove Jar Files window to add the Jar files (see Using CLOBs).

    Add/Remove JAR files

  7. In the Select Jar File window, select the classes12.jar file and click Import (see Using CLOBs).

    Select JAR file

  8. In the Add/Remove Jar Files window, click Close.

  9. In the Business Rules Designer, call the CLOB method by clicking the Class Browser button. The Class Browser dialog box appears (see Using CLOBs).

    Call CLOB Method

  10. Select empty_lob from the list of CLOB variables and click Select.

  11. Create a local variable by clicking the Local Variable button on the Business Rules toolbar. The Create Variable dialog box is displayed. (see Using CLOBs).

    Create Local Variable

  12. Name the variable myCLOB, select the Class type, and choose CLOB as the Class type.

  13. Click OK to create the variable.

  14. In the Business Rules Designer, drag the CLOB to the Local Variable using the Cast method. Click Yes when the incompatible Data Type warning appaers (see Using CLOBs).

    Drag CLOB Assign

  15. Use the CLOB putString method to assign 1 to Arg().

  16. In the Java Collaboration Editor, the Java code resembles the following:


    public void receive( com.stc.connector.appconn.file.FileTextMessage input,cLOB.
CLOBOTD CLOB_1 ) throws Throwable
{
    //@map:CLOB_1.getCLOB_TEST.insert
        CLOB_1.getCLOB_TEST().insert();

        //@map:Copy java.math.BigDecimal.valueOf(100) to CUSTOMER_ID
        CLOB_1.getCLOB_TEST().setCUSTOMER_ID( java.math.BigDecimal.
valueOf( 100 ) );

        //@map:Copy oracle.sql.CLOB.empty_lob to PROCESSED_TEXT
        CLOB_1.getCLOB_TEST().setPROCESSED_TEXT( oracle.sql.CLOB.empty_lob() );

        //@map:CLOB_TEST.insertRow
        CLOB_1.getCLOB_TEST().insertRow();

//@map:CLOB_1.getCLOB_TEST.select("customer_id = 100 for update")
        CLOB_1.getCLOB_TEST().select( "customer_id = 100 for update" );
//If
        if (CLOB_1.getCLOB_TEST().next()) {
            //@map:oracle.sql.CLOB myClob;
            oracle.sql.CLOB myClob;

            //@map:Copy cast PROCESSED_TEXT to oracle.sql.CLOB to myClob
            myClob = (oracle.sql.CLOB) CLOB_1.getCLOB_TEST().getPROCESSED_TEXT();

           //@map:myClob.putString(1,Text)
            myClob.putString( 1,input.getText() );

            //@map:CLOB_TEST.updateRow
            CLOB_1.getCLOB_TEST().updateRow();
}
    }
