Launcher won't load

nhs16 · June 29, 2012

Launcher Version: (1.0.1.3)

Operating System: Windows 7 - 64 bit

Java Version: 7-64bit

Antivirus Program: Trend Micro Titanium

Description of Problem:

When using the .exe, the loader only creates the .techniclauncher folder with the .jar files but nothing else happens.

When using the .jar download I get the following error message from java:

MissingFieldException[ The following required field is missing from the launch file: <jnlp>]

at com.sun.javaws.jnl.XMLFormat.parse(Unknown Source)

at com.sun.javaws.jnl.LaunchDescFactory.buildDescriptor(Unknown Source)

at com.sun.javaws.Main.continueInSecureThread(Unknown Source)

at com.sun.javaws.Main$1.run(Unknown Source)

at java.lang.Thread.run(Unknown Source)

Having looked at other similar posts, I have tried to uninstall java (from Control Panel/Install/Uninstall programs etc) and re-install it with no luck.

How are you trying to run the .jar file? Just a right-click and Run with Java or a batch file? If one doesn't work, try the other.

I have been trying to just right-click and and run with Java. I have tried to find out on google how to do it with a batch file but it doesn't really explain it clear enough for my limited techy skills.

Grab the server files for Tekkit, pull the launch.bat out of it, rename the .jar in that batch file, and change the amount of memory it uses if you want. You can rename the launch.bat too if you like.

nhs16 · June 29, 2012

Got the files, took the launch.bat out of the folder, renamed the .jar file to technic-launcher-latest, didn't change the amount of memory.

I then tried to right click open the new .jar file (with the Java Web Start launcher) and got this error message:

CouldNotLoadArgumentException[ Could not load file/URL specified: C:\\Users\\n\\AppData\\Local\\Temp\\javaws7]

at com.sun.javaws.Main.launchApp(Unknown Source)

at com.sun.javaws.Main.continueInSecureThread(Unknown Source)

at com.sun.javaws.Main$1.run(Unknown Source)

If I try to open it with the Java Platform SE binary (javaw.exe) nothing happens.

Torezu · June 29, 2012

So you tried to run that batch file? Have you tried adding the Java bin directory to your system path variable?

nhs16 · June 29, 2012

I guess so, not really sure. I had already added the Java bin directory to my system path variable.

Torezu · June 29, 2012

You want to open/run the batch file, not right-click > Open with Java. That clearly didn't work.

Right sorry, I extracted the zip on a folder in my desktop, I then ran the launch.bat file and it is stuck on Creating Railcraft Save File.

If I close the cmd and try to run the java tekkit.jar, with the Web start launcher, this message comes up:

Error: could not load javaws10 (the first time I tried), javaws11(the second time I tried).

Exception:

CouldNotLoadArgumentException[ Could not load file/URL specified: C:\\Users\\NACHOH~1\\AppData\\Local\\Temp\\javaws13]

Okay, I'd reinstall Java then (remove with control panel first of course). It seems like your Java install might be borked.

nhs16 · June 30, 2012

I uninstalled Java and re-installed Java 7 update 5 (64-bit). I then downloaded the .exe and .jar files again.

When I ran the .exe file it says that the launcher is downloading, gets to 100% and nothing happens.

When I ran the .jar file with Java plaform se binary nothing happens.

When I opened the .jar file with Java web start launcher I get this error message again:

MissingFieldException[ The following required field is missing from the launch file: <jnlp>]

Has anyone been able to find a solution to this problem?

Not a clue. The thread's a month old, why don't you try re-downloading the launcher again? It's been updated a time or two, even if the number's the same.

I have downloaded the Technic Launcher version 3.1.2.

I re-checked that I had the latest version of Java 64-bit working.

When I run the .exe file it says that the launcher is downloading, gets to 100% and nothing happens.

When I run the .jar file with Java web start launcher I get this error message:

MissingFieldException[ The following required field is missing from the launch file: <jnlp>]

at com.sun.javaws.jnl.XMLFormat.parse(Unknown Source)

at com.sun.javaws.jnl.LaunchDescFactory.buildDescriptor(Unknown Source)

at com.sun.javaws.Main.continueInSecureThread(Unknown Source)

at com.sun.javaws.Main$1.run(Unknown Source)

at java.lang.Thread.run(Unknown Source)

Should I open the .jar file and place those files somewhere instead?

Torezu · August 5, 2012

You shouldn't be running the .jar with the Web Start launcher...you should be running it with JRE7. Have you tried using a batch file to run it?
