My Lightstreamer doesn't start

Hi, I'm new with Lightstreamer and Java... I set up the Java Variables and uncompressed the Lightstreamer Moderato. But when the server it's trying to start it fails with this message: The system can not find the specified path. I already check the Ls.bat file and the error is with the class com.lightstreamer.ls witch is in the lightstreamer.jar file. I even check the forums and read that I need to make lightstreamer.jar accessible, but like I said I'm new in java and I don't know how to solve the problem.
I need help

Hi Noah,

Usally the "The system can not find the specified path" message refers to the JAVA_HOME variable set in LS.bat that is not a valid path for your machine.
Please double-check if you can reach the paths set in the JAVA_HOME and LS_HOME variables at the beginning of the script.

If the JAVA_HOME and LS_HOME are ok, please remove from the LS.bat script this line

Code:

---

    @echo off

---

and retry. We should get some further info about the issue.

Giuseppe thx for the reply I double-check the paths and they were OK, I remove

Code:

---

    @echo off

and try to run the server again and this is what appeared on console:

Code:

C:\Lightstreamer\bin\windows>call LS.bat run

C:\Lightstreamer\bin\windows>rem JAVA_OPTS should contain any Java Virtual Machi
ne options. Here are some tips:

C:\Lightstreamer\bin\windows>rem 1) Always use the "-server" option.

C:\Lightstreamer\bin\windows>rem 2) Give more RAM to the server process, especia
lly with heavy traffic, by specifying a min and max "heap"

C:\Lightstreamer\bin\windows>rem    E.g.: If you have 4 GB and the box is dedica
ted to Lightstreamer, you might set 1 GB min heap and 3 GB max

C:\Lightstreamer\bin\windows>rem    heap with these options: "-Xms1G -Xmx3G"

C:\Lightstreamer\bin\windows>rem 3) Choose a better "garbage collector" if you w
ant to reduce latency. An option that often gives good results is:

C:\Lightstreamer\bin\windows>rem    "-XX:+UseConcMarkSweepGC". If you are using
Java 7 (apart from early versions) or later, you might prefer to try:

C:\Lightstreamer\bin\windows>rem    "-XX:+UseG1GC". Many other tuning options ar
e available (please see Oracle docs).

C:\Lightstreamer\bin\windows>set JAVA_OPTS=-server

Hi Noah,

Please note that "C:\Program Files\Java\jdk1.7.0" is the JAVA_HOME assumed in the factory script. But the latest Java downloads installed itself in folders like:

"C:\Program Files\Java\jdk1.7.0_67"
or
"C:\Program Files\Java\jdk1.8.0_11"

Could you check, on your machine, where java.exe is actually present?

Thank you,
Giuseppe

thx Giuseppe, that's was the problem exactly... its running OK right now...
