Error java: "Dangling meta character '+' near index 0 + ^"

Hi,
I'm receiving a runtime error, when I was trying to run search engine (only when I insert a symbol "+" plus or "\" slash) in B2B (E-selling of CRM-ISA 5.0).
This is the text error:
<b>

split() takes a regular expression, not just simple text. The + symbol means something special. Try something like split("\\+TO\\+")

PatternSyntaxException: Dangling meta character '*' near index 0

Hi,
I am using DocumentFilter to control the input in a JtextField In accordance with model of a mask.
The mask can contain the following characters:
    // # : for =---> NUMBER only
    // ? : for =---> LETTER only
    // A : for =---> LETTER end for NUMBER
    // * : for =---> ANYTHING    I made a class that extends DocumentFilter and it look like this:
public class MydocumentFilter extends DocumentFilter {
public void insertString(...){
// do anything
    } // insertString()
public void remove(...)
// do anything
    } // remove()
@Override
    public void replace(
            DocumentFilter.FilterBypass fb,
            int offset, // posizione del cursore
            int length, // Length of text to delete (solo per sostituzioni...)
            String text,// testo da inserire
            AttributeSet attrs) throws BadLocationException {
// here are some controls that change the value of the text variable, and at last call the super class..:
        super.replace(fb, offset, length, text.replaceAll(text, replace), attrs);
    } // replace()
} // class MydocumentFilterI have a problem when the user write wildcards (='*' OR '?').
Then I get the message:
Exception in thread "AWT-EventQueue-0" java.util.regex.PatternSyntaxException: Dangling meta character '*' near index 0.I know that '*' and “?” are is a metachars and for that I added this code before calling super.replace(...);
        if (text.compareTo("*") == 0){
            replace = "\\*";
        }but I don't get the expected result. I get -\*- instead then -*-

All that many lines for a regex question (where the error message already pointed to), which has nothing to do with Swing. An SSCCE looks different.
if (text.compareTo("*") == 0){
replace = "\\*";
text = replace;
super.replace(fb, offset, length, text.replaceAll(text, replace), attrs);You must keep the text, the regex and the replacement string apart:
String text= "A", regEx= "A", rep= "B";
//String text= "*", regEx="\\*", rep= "*";
text= text.replaceAll(regEx, rep);
System.out.println(text);And why don't you use a JFormattedTextField with a MaskFormatter which does all the job for you.

Dangling meta character exception

Hi,
we get this exception after a readAll query with conformResultsInUnitOfWork. The presence of the "+" in the text seems to confuse toplink.
Is it a known bug or should we open a TAR?

I suggest you should alter the JDBC Driver and select one for Oracle 9i.
Which version is your JDev10g?

Error Connecting to MySql (character set index '49')

I downloaded the Oracle Sql Developer extensions and went to Tools / Preferences / Third Part and set the location for the Jar file.
When I try and test the connection to the MySql database I get this error:
An error was encountered performing the requested operation:
Unknown initial charater set index '49' received from the server.
Initial client character set can be forced via the 'characterEncoding' property.
Vendor code 0
My dba's used Sql developer to connect to the same MySql database fine. If I use MySql Workbench, I can connect. (I prefer Sql Developer, so I was hoping to get this connection to work.)
I even tried going to MySql to get their Connection/J JDBC jar file; but the same results.
Any suggestions?
Thanks,
Mike

Are your colleagues using the same sqldev/JDBC versions? Which?
Did you follow the guide on setting it up, and the driver from http://dev.mysql.com/downloads/connector/j/ ?

How to use : bind character in DB adapter Select Query SOA11g. Getting Error code :17003 .java.sql.SQLException: Invalid column index error

Hi All,
The Actual query to perform is below.
SELECT name,number from emp WHERE CASE WHEN :1='T' AND term_date IS Not NULL THEN 1 WHEN :1='A' AND term_date IS NULL THEN 1 WHEN :1='ALL' THEN 1 ELSE 1 END = 1;
I have tried in DB adapter like below as a parameter for :1 as #vInputParam
SELECT name,number from emp WHERE CASE WHEN #vInputParam='T' AND term_date IS Not NULL THEN 1 WHEN #vInputParam='A' AND term_date IS NULL THEN 1 WHEN #vInputParam='ALL' THEN 1 ELSE 1 END = 1;
Getting Error code :17003 .java.sql.SQLException: Invalid column index error.
Please suggest me on using ':' bind character in DB adapter Select Query SOA11g.
Can someone help me on this please?
Thanks,
Hari

Hi,
Could you please make sure your binding style(Oracle Positional,Oracle named..etc) of the Seeded VO and Custom Vo are same.
This is the option you will get when you are extending your vo. So make sure that both are same.
You can refer the below link too
VO extension leads to "Invalid column index" exception
Thanks

Unexpected internal error near index 1

Hi,
I am convering al l occurance of "\" into "/" in a string.
private String format(){
        input="java\\software\\";
        System.out.println("Before formating, input:" + input);
        try{
            input=input.replaceAll("\\", "/");
            System.out.println("After formating, Input:" + input);
        }catch(Exception e){
            System.out.println("Error in formatting:" + e.getMessage());
        return input;
    }And I am getting this Error:
Unexpected internal error near index 1
Any idea whats wrong with above code?

If you want to replace two backslashes with asingle
forward slash, then you need to specify the former
(as a regular expression) as "\\\\"OH! Thanks. I got another way and its working.
I am using
s.replace('\\', '/'); insteadd of
replaceAll
Yes, that's definitely better in this case, since that API is simpler for single-char replacements. If you sometime need to replace strings though (back to the replaceAll) you'll need to be aware of how regular expressions are formed and how the backslash character plays a part in forming them.

Unclosed character class near index 0

Hi foks,
I am tryin to remove few characters from a string with the help of replaceAll ( String, String ) method.
But at the first replacement itself it gives error "Unclosed character class near index 0".
what does this error mean? I dont have any ' [ ' character in that string. It used to be there, but now I am removing all the occuring of the ' [ ' char right at the creation of string.
Thanks in advance.

Hi,
Here is the code.
[ CODE ]
public static String extract(String para)
String definition = para.substring(para.indexOf("<ol>"),para.indexOf("</ol>"));
StringBuffer meanings=new StringBuffer();

StringWriter writer = new StringWriter();
boolean append=false;
int ch;
try
while((ch=reader.read()) != -1)
if(ch=='<' || ch=='&')
append = false;
continue;

PatternSyntaxException: Unclosed character class near index

Hi,
I want to replace in a string a expression like "^1:2" by "^(1/2)":
For example, "V/Hz^1:2" would be converted to "V/Hz^(1/2)".
I tried the following code:
String oldExponent = "[^](\\d+):(\\d+)"; // e.g. ^1:2
String newExponent = "^($1/$2)"; // e.g. ^(1/2)
myString = myString.replaceAll(oldExponent, newExponent);but the following exception is thrown in the third line:
java.util.regex.PatternSyntaxException: Unclosed character class near index 13
[^](\d+):(\d+)
^Any idea?
Thanks in advance.

Thank you, jverd, you are pretty right.
Now I tried with
"\\^(\\d+):(\\d+)"and it works.
I tried to avoid ^ being interpreted as the beginning of the line, and didn't realize the interpretation inside the brackets.
Escaping this character works well.

Portal error : java.lang.IndexOutOfBoundsException: Index: 2, Size: 2

Hi Experts,
Through protal I am changing Other Bank details (IT0009 subtype 0001) for US employee.
I get the error java.lang.IndexOutOfBoundsException: Index: 2, Size: 2 when I am edditing the other bank details.
Please help me out in this.
Prasad

Hi,
java.lang.IndexOutOfBoundsException occurs when the runtime environment tries to access the index of an array which doesn't exist. (Index 2 = third entry, you only seem to have 2 entries though).
Are you certain, the Pernr's Infotype is maintained correctly?
Could you post the entire error log from NWA so we can see the JAVA Stack? Maybe the error is nested.
Check Notes 1356222 and 1359671 as well. They might solve your error right away.
best regards, Lukas

Sorry for the late reply.
It is problably a problem with the configname attribute of the ApplicationModule tag which is wrong.
Can you try to open the JSP file with the problem and look at the ApplicationModule tag setting.
If you create a new ApplicationModule tag under it using the Component Palette, it will give you a clue to what setting is espected for the configname. Make sure to keep the same value for the "id" property.

Hi K,
Whats the default character set of you MySQL and Oracle Databases.
What version of JDBC driver are you using?
Is there any unicode characters used in your data?
Have you tried offline data move?
Thanks

Unknown initial character set index '48'

Hello,
I have installed today the Mysql connector/j and every time I try to connect to mysql I get the following error.
"java.sql.SQLException: Unknown initial character set index '48' received from server. Initial client character set can be forced via the 'characterEncoding' property."
The line that produces this error is the following:
conn = DriverManager.getConnection (url, userName, password);
I have read some solutions from other people faced the same error as me but nothing really helped me.
I have changed the character-set-server = latin1 and the collation-server = latin1_swedish_ci lines of win.ini several times today but no luck.
Anyone know what should I do to manage to connect to the database?

just in case anybody else face the same problem as I did, the solution that worked for me is to install an older version of connector/j.
I had the problem with mysql-connector-java-5.0.4 but with mysql-connector-java-3.1.14 everything is fine and I can now connect to my db.

While opening SXMB_IFR i am getting a error Java.lang.noclassFounderror

U have installed SAP XI in my laptop while opening
SXMB_IFR i am getting a error Java.lang.noclassFounderror
so i not able to go further please help me
thanking you
sridhar

Hi,
There are number of ways to do that :
1. Try this url
http://<host-name or IP address of XI server>:<java Port number)>/rep/start/index.jsp
If this is successful that means your J2EE server and services are fucntioning fine. The problem could then be on the ABAP stack.
2. Can you start visual admin tool and check that all the services are running. You might have to manually start those which have not automatically started. Check the connectivity with all system & server (inc n/w) & Register the hostserver entry in your sys32/ host file
e.g 10.2.4.56 <server name>
3. Have you download java sdk 1.4 on you laptop?
http://java.sun.com/j2se/1.4.2/download.html
also have a look at this sap note: 801868
(make sure not to install the 1.5 version of JWS. XI does not work properly with the 1.5 version)
4. Lastly, u might have some problem with ur JRE installation. In that case i would sugesst you to re-install JRE/ Java WebStart.
This blog may help you to analyze the errors-
