Hi Kolusu,
Thanks for information. I followed the instructions as mentioned to compile the HelloWorld.java program, however it is throwing errors saying that main() and all other java keywords are invalid. I checked java1.7.0_64 is installed in our shop. Is there anything else I need to do to compile java pgm.
Thanks,
Sivakumar Jetty. |

sjetty,
well you need to make sure you have the right path. To find the right path.
1. Issue TSO ISH or simply ISH depending on how your shop is configured
2. Change the path name to etc/profile
3. You will see a text file and there look for PATH environment variable.
4. COPY the PATH name and EXPORT (the last 2 lines)
5. Exit
Now go back to example show in the link and then issue the path and export command before compiling (step 9 in that link)

Hi Kolusu,
After searching path in etc/profile I found below path.
| Code: |
BROWSE /etc/profile CHARS 'path' found
Command ===> Scroll ===> PAGE
# ======================================================================
# Execution path
# ======================================================================
PATH=.:/usr/lpp/java/J7.0_64/bin:/bin:/usr/sbin:/usr/lpp/coz/bin
export PATH
# ======================================================================
|
After entering path ,export command in OMVS I tried to complie my java pgm, but still I am getting same error.
| Code: |
$ PATH=.:/usr/lpp/java/J7.0_64/bin:/bin:/usr/sbin:/usr/lpp/coz/bin
$ export PATH
$ javac test.java
test.java:3: error: illegal character: \168
public static void main(String args[])
¬
test.java:3: error: illegal start of type
public static void main(String args[])
¬

¬
test.java:4: error: ';' expected
{
¬
test.java:5: error: illegal start of type
System.out.println("hello");
¬
test.java:5: error: ';' expected
System.out.println("hello");
¬

System.out.println("hello");
¬
test.java:5: error: illegal start of type
System.out.println("hello");
¬
test.java:7: error: class, interface, or enum expected
}
¬
9 errors

Can you please let me if I am missing anything here.
Thank,
Sivakumar. |

sjetty,
You just need till bin portion and the rest is not needed.
PATH=/usr/lpp/java/J7.0_64/bin
$ export PATH
Also looks like you sent a file from PC side and it resulted in Byte order mark. You can force it to use UTF8 Encoding by the following
| Code: |
javac -encoding UTF8 test.java
|
Try with a simple program first and then you can play around stuff later.
Follow this
1. Type OMVS. (If your userid has been set up to use Unix System Services it should start you in a directory (mine being "/u/userid").
2. Since you already created a directory we can skip the creating of directory and sample program
3. Make sure your HELLO.JAVA has the following
| Code: |
public class Hello{
public static void main(String args[]){
System.out.println("Welcome!");
}
}
|
4. Issue the command the following command and press enter
| Code: |
PATH=/usr/lpp/java/J7.0_64/bin |
5. Issue the command the following command and press enter
6. Compile the resulting java with "javac -encoding UTF8 Hello.java".
7. Run the compiled java bytecode with "java Hello".

Hi Kolusu,
I have used the path till bin and issued PATH and EXPORT command in the directory where i have my java code.After issuing command javac -encoding UTF8 test.java, it throwed aroubd 90 errors.
Below code i have written in ISHELL and not transmitted from PC.
| Code: |
EDIT /u/uid/siva/test.java Columns 00001 00072

I am still facing the same issue. Is it like that my path is not is being properly, if so how can we verify whether the path is set correctly or not.
Thanks,
Siva |

Siva,
Stop using such phrases. You compile and you get errors, that's all and there is NO throwing involved.
Secondly, the issue is with how you are copying and pasting. Looks like your COPY and PASTE is messing up the Square brackets or inserting additional characters at the end.
Make sure that you have X'AD' for [ and X'BD' for ]
Type HX7 on line 1 and see if you have any other junk characters at the end of each line
this is how your program should be when you turn on HEX
| Code: |

When in HEX On I could see X'BA' for [ and X'BB' for ] and not X'AD' for [ and X'BD' for ].

Even I tried to check the values for [] in a flat file. Still I don't see X'AD' for [ and X'BD' for ].

Can you please let me know how can I get the correct values for []. So that my pgm would compile.
Thanks,

Sjetty,
Looks like your mainframe encoding scheme is not 1047 or 0037.

Simply type HX as the line command and over type the value the X'BD' and save it and you should be able to compile.
