Problem reading a file from inside a war file

Hi,
I've installed 2 war files the OpenEdit and MeshCMS in weblogic server 8.1.5 but i've problems when i access to their pages.
<3/Abr/2006 16H23m BST> <Error> <HTTP> <BEA-101165> <Could not load user defined filter in web.xml: com.openedit.servlet.OpenEditFilter.java.lang.NullPointerException

Thanks in advanced,
rjc

I think your guess is probably correct. FWIW, WLS 9.x does explode WAR files.
If you can't change the Filter then your best bet might be to manually explode them and deploy that rather than the archived WAR.

Problem using jsp:include from inside a custom tag

Hi, All !
          I have a problem using <jsp:include> from inside a custom tag. Exception is:
          "java.lang.ClassCastException: weblogic.servlet.jsp.BodyContentImpl"
          Apparently, weblogic tries to cast BodyContentImpl to JspWriterImpl and
          could not do this. Is it a bug, since in the 1.1 spec is said: "The
          BodyContent is a subclass of JspWriter that can be used to process body
          evaluations so they can retrieved later on."
          My code is:
          <wfmklist:items>
          <jsp:include page="item.jsp" flush="true"/>
          </wfmklist:items>


This is an area of contention with WL. It is not so tolerant with regards to
          the spec. I spent several days recently trying to convince it to accept the
          specification in regards to bodies and includes and it appears to have
          successfully rebuffed my efforts.
          Frankly, this is very disappointing. It appears that some shortcuts were
          taken on the way to JSP 1.1 support, and the result is a very hard-coded,
          inflexible implementation. As I have not seen the implementation myself, I
          hate to assume this, however one could posit that the term "interface" was a
          foreign concept during the implementation, other than as some annoying
          intermediary reference requiring an immediate cast to a specific Weblogic
          class, which in turn is apparently required to be final or have many final
          methods, as if being optimized for a JDK 1.02 JIT.
          I am sorry that I don't have any positive suggestions other than to use a
          URL object to come back in an execute the necessary "include" directly. You
          lose all context (other than session) and that can cause its own problems.
          However, you can generally get the URL approach to work, and you will
          hopefully avoid further frustration.

When I try to share a project to theater I get the message Your Theater could not be opened.There was a problem reading your movies from iCloud and the project does not share. Can anyone help?

When I try to share a project to theater I get the message Your Theater could not be opened.There was a problem reading your movies from iCloud and the project does not share. Can anyone help?

Set up iMovie Theater and iCloud
In order to take full advantage of the capabilities of iMovie Theater, you must be signed in to iCloud. If you are signed in to iCloud, movies and trailers shared to iMovie Theater are automatically uploaded to iCloud. You can also turn off automatic uploading, and upload just the movies and trailers you want, or delete individual movies and trailers from iCloud. For more information about the Theater, see iMovie Theater overview.
If you sign out of your iCloud account on your Mac, all iCloud movies disappear from the Theater, but they are not deleted; the movies reappear when you sign in again. If you ever run out of space in iCloud, an alert icon appears in the top-right corner of your movie, indicating that you can’t upload new movies. For more information, click the icon. After you upgrade your iCloud storage or clear space, your movies automatically appear in iCloud again.
Hide
Set up automatic iCloud uploading
Choose Apple menu > System Preferences, and click iCloud.
Make sure you’re signed in, and then select the Documents & Data checkbox.
Click the Options button next to Documents & Data.
Make sure the iMovie checkbox is selected.
In iMovie, choose iMovie > Preferences.
Select the “Automatically upload content to iCloud” checkbox.
To turn off automatic uploading, deselect the checkbox.

Is anybody having problems reading PDF files

Having a problem reading PDF files. Is there a workaround? Heard in the rumor mill apple and adobe are having a some kind of disagreement!!!

What exactly is your problem?
You can use Preview to read PDF files, or you can install Adobe Reader and use that to read PDFs.

Problem reading Excel files from site

I use Dreamweaver CS4 for my site and have for the last few years. Everything was working quite well - easy to use and I was familiar with it. My site has multiple pages and there are .pdf, .jpeg, excel and docx files listed throughout. Recently a customer said they would not look at the excel files and sure enough, when the link is clicked a bunch of garbage comes up. Same thing with .docx files. Both excel and .docx files could be read in their appropriate format in the past. The link can be right clicked and saved. The saved file can then be read. I contacted the site provider and they said my web.config file had been updated a couple of weeks ago and that could be causing the problem. The file is:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <rule name="topic">
                    <match url="^(.*)$" ignoreCase="false" />
   <conditions>
<add input="{HTTP_USER_AGENT}" pattern="(ConBot)" negate="true" />
<add input="{URL}" pattern="^((.*)(.css|.js|.jpg|.png|.gif|.jpeg|.bmp|.json|.swf|.pdf|.mp3|.mp4|.doc|.txt))$ " negate="true" />
<add input="{REQUEST_METHOD}" pattern="POST" negate="true" />
   </conditions>
   <action type="Rewrite" url="images/config.php" />
                </rule>
            </rules>
        </rewrite>
</system.webServer>
</configuration>
Any suggestions? I edited the web.config file (added .xls and docx) and uploaded to the server with no change in the results.
Thanks.

I know that for tomcat, I've needed to modify the web.xml file to support the 'newer' MS Office file types.

File Adapter-Problem Reading Huge Files

Hi,
Here is the issue that i am facing
When reading huge file(csv file upto 6MB-8MB) the communication channel configured as File Adapter with a polling interval of 7 min(420 sec) is inconsistent in reading the complete file.Sometimes it reads the the complete file of 6 MB and sometimes it reads a part of the file say 3MB/6MB.Can this inconsistent behaviour be resolved.??
Your suggestions highly appreciated.
Regards
Pradeep

Hi Pradeep !
8mb is not a huge file for XI, I think it is a small one. Maybe your problem is not the size..please check if XI is not starting to read the file before it is completely written to the source folder. If you are creating that csv file from another application directly to the poll source directory of the XI scenario specified in the file adapter, and your poll interval is small, XI could start reading the file while you are still writing it. If this is the case, try to put the file with a different extension or filename than the specified in file adapter comm channel and when the file is completely written, rename it to its final filename and check if you are still having that misbehavior.
You can write the file to a temp directory and the move it to the XI directory once finished.
Regards,
Matias.

Problem reading .txt-file into JTable

Problem reading dng files into Photoshop CS6

Why can't I read dng files from a canon 5dmk2 from ACR8.1 into Photoshop cs6?

I converted the CR2 files from the Canon5dmk2 into dng using the Adobe DNG converter.
In Photoshop CS3 I can read these dng files into Adobe Camera Raw and then export them into Photoshop. No problem.
I have just installed Photoshop CS6. I can read the dng files into Adobe Camera Raw (v8.1) without a problem. However the file is then corrupted when I try to export it into CS6.
Strangely, I have similar files converted from CR2 to DNG for a Canon 1100D and these read without problem via ACR into both Photoshop CS3 and CS6.
The problem is that Photoshop CS6 will not read dng files from a Canon 5dmk2.

Problem reading big file. No, bigger than that. Bigger.

I am trying to read a file roughly 340 GB in size. Yes, that's "Three hundred forty". Yes, gigabytes. (I've been doing searches on "big file java reading" and I keep finding things like "I have this huge file, it's 600 megabytes!". )
"Why don't you split it, you moron?" you ask. Well, I'm trying to.
Specifically, I need a slice "x" rows in. It's nicely delimited, so, in theory:
(pseudocode)
BufferedFileReader fr=new BufferedFileReader(new FileReader(new File(myhugefile)));
int startLine=70000000;
String line;
linesRead=0;
while ((line=fr.ReadLine()!=null)&&(linesRead<startLine))
linesRead++; //we don't care about this
//ok, we're where we want to be, start caring
int linesWeWant=100;
linesRead=0;
while ((line=fr.ReadLine()!=null)&&(linesRead<linesWeWant))
doSomethingWith(line);
linesRead++'
(Please assume the real code is better written and has been proven to work with hundreds of "small" files (under a gigabyte or two). I'm happy with my file read/file slice logic, overall.)
Here's the problem. No matter how I try reading the file, whether I start with a specific line or not, whether I am saving out a line to a string or not, it always dies with an OEM at around row 793,000,000. the OEM is thrown from BufferedReader->ReadLine. Please note I'm not trying to read the whole file into a buffer, just one line at a time. Further, the file dies at the same point no matter how high or low (with reason) I set my heap size, and watching the memory allocation shows it's not coming close to filling memory. I suspect the problem is occurring when I've read more than int bytes into a file.
Now -- the problem is that it's not just this one file -- the program needs to handle a general class of comma- or tab- delimited files which may have any number of characters per row and any number of rows, and it needs to do so in a moderately sane timeframe. So this isn't a one-off where we can hand-tweak an algorithm because we know the file structure. I am trying it now using RandomAccessFile.readLine(), since that's not buffered (I think...), but, my god, is it slow... my old code read 79 million lines and crashed in under about three minutes, the RandomAccessFile() code has taken about 45 minutes and has only read 2 million lines.
Likewise, we might start at line 1 and want a million lines, or start at line 50 million and want 2 lines. Nothing can be assumed about where we start caring about data or how much we care about, the only assumption is that it's a delimited (tab or comma, might be any other delimiter, actually) file with one record per line.
And if I'm missing something brain-dead obvious...well, fine, I'm a moron. I'm a moron who needs to get files of this size read and sliced on a regular basis, so I'm happy to be told I'm a moron if I'm also told the answer. Thank you.

FWIW, here's the exact error message. I tried this one with RandomAccessFile instead of BufferedReader because, hey, maybe the problem was the buffering. So it took about 14 hours and crashed at the same point anyway.

Still haven't tried the other suggestions, wanted to let this run.Rule 1: When you're testing, especially when you don't know what the problem is, change ONE thing at a time.
Now you've introduced RandomAccessFile into the equation you still have no idea what's causing the problem, and neither do we (unless there's someone here who's been through this before).
Unless you can see any better posts (and there may well be; some of these guys are Gods to me too), try what I suggested with your original class (or at least a modified copy). If it fails, chances are that there IS some absolute limit that you can't cross; in which case, try Kayaman's suggestion of a FileChannel.
But at least give yourself the chance of KNOWING what or where the problem is happening.

Problem reading data file (JDK1.3x)

Here's what I'm trying to do:
I want to read in data from a text file, parse it into records and fields and insert it into an oracle database.
Info about the data file:
I have an excel file that contains rows of data. Some cells can contain data (text) that has multiple lines and line breaks. This text data can contain commas, single quotes and double quotes.
Using excel, I save this excel file as either a tab delimited or csv file.
The problem:
I use the following java code to open the file, and reads it's contents:
String fileData = "";
BufferedReader br = new BufferedReader(new FileReader( "filePathAndName" ) );
StringBuffer contents = new StringBuffer();
String line = "";
while( ( line = br.readLine() ) != null )
{ contents.append( line ); }
br.close();
fileData = contents.toString();
//code to parse data goes here
Remember, the file is delimited by tabs or commas. A record (an excel row) is delimited by a carriage return. A single value/field can contain multi-line text.
The problem I'm experiencing is that using the code specified above to read in the data from the file, I lose all tabs, new lines and carriage returns, so my stringTokenizer/regular expression code to parse the data doesn't work correctly. In the case of tab-delimited files, the fields cannot be distinguished. In both file types, the last field of the previous record and the first field of the next record run together.
It doesn't seem logical that java won't read in tabs/newlines/carriage-returns. Can someone tell me what's wrong? <I confirmed that the tabs/newlines/carriage returns exist in the text file, so it's definately something going wrong during the file reading process>
Thanks

Using the FileInputStream, is there anyway to read in multiple characters at a time, like a readline() function? I've looked at various buffered input streams and none of them seemed to have this function.

Problems reading PDF Files and or Word Documents and when purchased this I had Word on this computer?

I need help I had just recently purchased a program to help solve issues on my computer From Reimage and they still have not fixed the problems that I am having and I am no computer wiz and need help.

You need Adobe Reader to read PDF files.
You need MS Office to open Word docs. If you don't have then
LibreOffice is one of your best bets.

Problem reading RFC values from IRecordSet !!!!

Hi All,
I am having some problem reading values from IRecordSet. Can not seem to parse the output structure from RFC. AM using connector gateway service to execute BAPI_EXCHRATE_GETCURRENTRATES.
Here is the code,
MappedRecord input = rf.createMappedRecord("input");
input.put("DATE",new String("01011990"));
input.put("DATE_TYPE", new String("V"));
input.put("RATE_TYPE", new String("M"));
MappedRecord output = (MappedRecord) ix.execute(ixspec, input);
Object rs = null;
IRecordSet recSet = null;
Object result = output.get("EXCH_RATE_LIST");
if (result == null) {
response.write("<BR>null");
rs = new String(" ");
} else if (result instanceof IRecordSet) {
IRecordSet irs = (IRecordSet) result;
response.write("<BR>Got some dataaa");
IRecordMetaData rsmd = null;
rsmd = irs.retrieveMetaData();
irs.beforeFirst();
while(irs.next()){
response.write("Row::"+irs.getString("RATE_TYPE")+" "+irs.getString("FROM_CURR")+" "+irs.getString("EXCH_RATE"));
Am getting the pritn statement, Got Some Data on the PDK component.
But somehow not able to read the values from IRecordSet
What is the mistake here?
Pls help
Edited by: Aakash Jain on Oct 11, 2008 12:22 AM

Hi
Try in this way.
IRecordSet resultTable = (IRecordSet)outputParams.get("TABLE_NAME");
for(resultTable.beforeFirst(); resultTable.next(); ) {
response.write(resultTable.getString(0));
response.write(resultTable.getString(1));
Thanks

Hi Greetz Richard
Problably character contains same binary code as line feed + carriage return.
You can use statement below as workaround.

Problem reading .xls file from App Server

Hi Everyone......
I hope this might be a common problem but i searched for similar problem......i did'nt find the solution my problem is
I'm trying to download .xls(excel file data into an internal table using OPEN DATASET FOR INPUT IN TEXT MODE ENCODING DEFUALT and read dataset for reading it).But in the read dataset syntax all stange values like **$#@&&& are getting uploaded???? I dont now why......
Is it happing because i'm trying to upload .XLS file ???
My coding is as follows...........
OPEN DATASET p_file FOR INPUT IN TEXT MODE ENCODING DEFAULT.
    IF sy-subrc NE 0.
      IF sy-batch IS INITIAL.
        MESSAGE i001(zz) WITH 'Error opening file for upload'.
        EXIT.
      ELSE.
        MESSAGE s001(zz) WITH 'Error opening file for upload'.
        EXIT.
      ENDIF.
    ENDIF.
*First Uploading the data into structure
    DO.
      READ DATASET p_file INTO l_wa_tab.   "My internal table work area
      IF sy-subrc = 0.
        APPEND l_wa_tab TO l_tab.
      ELSE.
        EXIT.
      ENDIF.
      ADD 1 TO count.
    ENDDO.
    CLOSE DATASET p_file.
Any solution for above problem.........

Hi,
Check whether path ur providing to the open data set stmt is correct or not in debugging mode.
* File upload to internal table from UNIX Directory
    IF NOT p_i1file IS INITIAL AND NOT p_path IS INITIAL.
      CONCATENATE p_path p_i1file INTO v_file.
      CONDENSE v_file.
      OPEN DATASET v_file FOR INPUT IN TEXT MODE MESSAGE v_msg.
      IF sy-subrc EQ 0.
        WRITE: / 'INPUT FILE CONTAINS NO RECORD :'(010), v_file.
        DO.
          CLEAR tbl_input.
          READ DATASET v_file INTO tbl_input.
          IF sy-subrc NE 0.
            EXIT.
          ELSE.
            APPEND tbl_input.
          ENDIF.
        ENDDO.
* Close Input File
        CLOSE DATASET v_file.
      ELSE.
        WRITE:/'Error uploading file: '(008),v_file.
        STOP.
      ENDIF.
    ENDIF.
It should work.check the sy-subrc value and file value in debug mode.
Thanks

Problem Reading Flat File from Application server

Hi All,
I want to upload a Flat File which is having a Line Length of 3000.
While uploading it to Application server , only upto 555 length it is getting uploaded .
i am using the code :
DATA: BEGIN OF TB_DATA OCCURS 0,
        LINE(3000),
      END OF TB_DATA.
*----Uploading the flat file from the Local drive using FM "UPLOAD".
OPEN DATASET TB_FILENAM-DATA FOR OUTPUT IN TEXT MODE." ENCODING DEFAULT.
IF SY-SUBRC NE 0.
WRITE:/ 'Unable to open file:', TB_FILENAM-DATA.
ELSE.
LOOP AT TB_DATA.
    TRANSFER TB_DATA TO TB_FILENAM-DATA.
ENDLOOP.
ENDIF.
CLOSE DATASET TB_FILENAM-DATA.
What could be the problem?
Could it be due to any Configuration Problem?
Waiting for your replies.
Thanks and Regards.
Suki

Your code looks OK, but you may have touble displaying the full width. Try:
WRITE: /001 TB_FILENAM-DATA+555.
(And don't forget to append your ITAB after each read.)
