This code works fine for xml files < 6MB, but its giving outOfMemory for 6MB and above file.

When to use CLASSPATH for .jar files

I find I must put newly added .jar files in my classpath in order to avoid "does not exist" errors when I compile. Where should .jar files be placed in order to avoid hardcoding this in my classpath?

Actually. With this .jar file (ksoap-midp.jar) which I downloaded, I can't resolve the imports even when I put the .jar in my classpath. What are the steps to take to add new classes to your system?

"Cannot interpret data in file" error while using GUI_UPLOAD for .xls file

Hi,
 I have made a program using FM GUI_UPLOAD to upload an .xls file to an internal table. But upon executing ,it gives error "Cannot Interpret data in file". I have seen in other posts people talking about GUI_UPLOAD FM to upload data from excel directly into internal table. Kindly help.
Here is my code. I had tried using different combination for HAS_FIELD_SEPARATOR but still its not working.
In my emp1.xls file , the data in each column is present in the same order as in the internal table. Although the first column in my internal table is NUMC. I dont know if that is causing the problem.

How to use 3rd party jar files for xml transform

Hi all,
Am using OAS9.0.4 and I deployed my .ear successfully.
In my application am using 4 jar files for xml transformation. (xerces.jar, xalan.jar, xml-apis.jar,xercesImpl.jar)
OAS has its own xmlparserv2.jar file. Its using this jar file for transforming xml data and not even looking for above mentioned 4 jar files.
In opmn.xml, I provided these 4 jar files in to class path. Then also it didn't effect my output.
I also tried as put these 4 jar files into j2ee\home\applib directory, but o result.
Can anybody tell me where should I keep these 4 jar files in OAS and OAS should use these 4 jar files instead of its own xmlparserv2.jar for transforming data.
Thanks in Anticipation,
Regards,
RK

Add the Xbootclasspath variable in the java-options field. It will somewhat look like the following in your opmn.xml file
<process-type id="<OC4J Instance Name>" module-id="OC4J">
<module-data>
<category id="start-parameters">
<data id="java-options value="........... -Xbootclasspath^/a:<location of your jar files>" />
Ensure to use th ^/a (append) signature

IO Error while deploying application client jar file ???????

Hi,
In my .ear file, one application-client jar(which contains all helper classes which are used in whole application) file is there. While deploying .ear file, all ejb are getting deployed well, while deploying application client jar file(Global.jar file here) it is giving the following message:
IO Error deploying Global.jar: D:\oracle9ias\oc4j_extended\j2ee\home\applications\trainiumear\Global.jar
Here is application-client.xml of Global.jar file:
<?xml version="1.0" encoding="UTF-8"?>

<description>Application description</description>
</application-client>
My Environment: Oracle9iAS (9.0.3.0.0), Windows-NT
Please let me know Why i am getting 'IO Error' , where i may done wrong ?
Thanks in Advance
Srinivas

Srinivas,
Before we continue, PLEASE tell me if you've looked through the available
documentation, code samples, "how-to" documents, etc., for OC4J. It
seems to me that you're mixing things up a bit. I use the "deploy"
command to deploy my EARs, example (partial):
java -jar admin.jar ormi://<host> admin <password> -deploy ...
And my EAR file is not in the "application-deployments" directory
when I issue that command.
Perhaps you could also show me the contents of your "application.xml"
file for this application you are having trouble with.
But I repeat, please tell me if you have already looked at the
available documents regarding OC4J!
Thanks,
Avi.

Blank spaces while using GUI_DOWNLOAD for Chinese characters

Hi,
While using GUI_DOWNLOAD for chinese characters I have used a code page option of 8300 for Chinese.
The file which is getting downloaded in a notepad has some Chinese characters coming under some headings.
After that columns other columns are getting shifted towards the right.
This is working correctly for English characters.
Can someone please help me.
Now I am using CL_GUI_FRONT_END_SERVICES=>GUI_DOWNLOAD.
What special options should I pass now.
Regards,

Hi,
I only solved my problem by using different code pages 8400 and 8300 for Chinese and Taiwanese characters.
I fixed the lengths of the fields by converting them to hexadecimal string and back to string using these function modules as below.

 lv_temp TYPE string.
DATA: lv_conv TYPE REF TO cl_abap_conv_in_ce.

Framemaker uses $filename for short file name, can we edit this to change appearance? We do not want the short file name of long filename to include the .fm extension can this be removed or modified to make this happen?

Framemaker uses <$filename> for short file name, can we edit this to change appearance? We do not want the short file name of long filename to include the .fm extension can this be removed or modified to make this happen? In compiling our books it would be helpful to not have this extension appear as it then requires us to create extra files without them.

Sender file adapter - Can I use *.xml for the file name

Hi Gurus,
I have some interfaces where I need to pick the file from a directory. The name of the file will have Datatime stamp as the naming convention. Can I use *.xml to pick up my files from this directory?
The help.sap.com documentation says that we can use this naming convention.

● File Name
Specify the name of the file that you want to process. The name can contain placeholders (*, ? (placeholders for exactly one character)) so that you can select a list of files for processing.

I tried using *.xml for my file name in the communication channel, XI is not picking up this file.
Please let me know if you have the solution.
Thanks
Kalyan

Murthy,
Thanks for the reply.
I am using GuildFTP tool as my FTP server. In this tool, all the permissions were given for the file to pick up.
The status of the file is good.
Where in the file adapter configuration I have to select 'Read-only'?
The file adapter is working perfect with the exact name of the file.
Thanks
Kalyan
